    description
    [001] The present invention relates to a device that can be used on a user's body to provide vacuum for clinical uses, especially for the vacuum treatment of injuries to the human or animal body, with a vacuum generator set and a disposable container after use, intended to receive bodily fluids, especially from segregations aspirated from a wound, and with a coupling for a suction line that is conducted to the body for this purpose, and the vacuum generator set is provided within or next to a first section of the housing of the device, the container forming a second section of the housing of the device or is disposed within or next to the second section of the housing and said sections of the housing can be fixed against each other in a separable manner, and the The device has fastening means, so that they can be used and transported on the user's body.
    [002] Devices of this kind for the treatment of vacuum injuries have already come to be known in several versions, especially according to the documents US 2004/0073151 A1, WO 2009/047524 A2, WO 2007/030599 A2 and EP 1 905 465 A1.
    [003] In these devices for vacuum treatment of wounds, a set that generates a vacuum communicates, through a suction line with the wound or with the surrounding of the wound, with an air-impermeable covering material for the air-tight closure of the wound and the wound surroundings, so that a vacuum can be produced in the wound compartment, and liquids can be sucked into the wound compartment into the said container.
    [004] The expression of a vacuum designates, in connection with the present invention, a reduced air pressure compared to the ambient air pressure (atmospheric air pressure), especially within a dressing. The dressing material for an air-tight closure of the wound compartment must therefore be shaped in such a way that it can withstand the pressure differentials that arise so that the vacuum in the wound compartment can be applied and sustained. In the context of vacuum therapy in the treatment of injuries, the vacuum will be indicated quantitatively as a pressure differential between the ambient air pressure and the air pressure applied below the cover material. Typically this pressure differential in the context of vacuum therapy is a maximum of 250 mm Hg (mm of mercury column) (1 mm Hg = 1 Torr. = 133.322 Pa). This vacuum range up to a maximum of 250 mm Hg has been shown to be suitable for wound healing. A preferred vacuum range is between 10 and 150 mm Hg.
    [005] The vacuum applied to the wound using the device, in the case of a typical vacuum treatment, can either be temporarily maintained in an essentially constant manner or it can be temporarily modified, especially being able to be changed cyclically, which can be achieved through a corresponding conformation control and programming device in the vacuum generator set, especially depending on other parameters.
    [006] For the application of vacuum and preferably also for the suction of bodily liquids, a suction line is provided, preferably flexible, for example, in the form of a drain that on the one hand communicates through a mouth in the region of the covering material of the wound with the surrounding of the wound, or with the wound compartment and, at the other end, communicates with the container already mentioned to receive bodily fluids, that is, with the vacuum generator set.
    [007] In addition to the vacuum treatment of wounds, other uses of the device mentioned here can also be envisaged to provide vacuum for clinical uses, especially aspiration of wound segregations, possibly with the use of washing fluids, also without the application of vacuum. in important time frames.
    [008] The objective of the present invention is to improve a device of the type described above, in the sense that it can be manipulated and operated in an even more comfortable way for the user.
    [009] In a device of the species mentioned according to the invention, this task is solved by the fact that the first section of the housing in a state in which it is transported on the user's body when the device is designated as being in mobile operation, finding it moves away from the body, whereas the second section of the housing is designed facing the body, and both sections of the housing, essentially have a discoidal shape and reciprocally touch through an essentially vertical projection divider. The discoidal conformation of the two sections of the housing represents in the sense of the present invention that the sections of the housing, when positioned in stationary service, with their vertical side as intended, on a horizontal base, presenting a width and a height which, considered given the possibility of horizontal direction, they are greater. The sections of the housing, therefore, when they are reciprocally fixed in a separable manner, touch each other with their sides facing the discoidal plane. When the dividing plane was mentioned above, this does not necessarily indicate that the housing sections touch reciprocally across an exactly flat surface. On the contrary, advantageously projections can be provided, as means of centralization, or similar units of similar profiling in a preferably complementary form, can be provided in a reciprocal direction in the housing sections. According to the invention, the two sections of the housing, therefore, will not be superimposed or stacked, however they are positioned side by side and against each other in the entire dividing plane, essentially of vertical projection, when the device, according to its destination, is positioned with its positioning side on a horizontal surface or when it is carried on a person's body, standing.
    [0010] Due to the fact that the container that forms the second section of the housing or that is integrated within or next to the second section of the housing, together with the second section of the housing, in the mobile operation of the device is facing towards the body and the first section of the housing that generates the vacuum is oriented away from the body, and it is possible to cover the second section of the housing, so to speak, with the first section of the housing. In this way, the second section of the housing or the container would also have to be made transparent, without direct viewing by a third person. In addition, the arrangement of the second housing section in the body region ensures greater conformation possibilities for suitability to the body than this would be the case in the first housing section, a vacuum generator. In addition, due to the arrangement, in relation to the body, from the first section of the housing, access to the control elements for the vacuum generator set and its control could be provided within the scope of the device's visualization. In this way it is also possible to access the device directly by the user, and the control components and possibly also the indicator components would then be arranged at a distance from the body and preferably visible from the top.
    [0011] In another embodiment of the invention it proved to be especially advantageous that the second section of the housing, on its side facing towards the user's body, towards the user's body, in at least one preferably horizontal plane, has a concave conformation, so that it can be applied to the body in an ergonomic way. Therefore, for example, the device can be used on the body in a comfortable way for the user in the waist region. The aforementioned plane is projected in this case, with the user / patient in a vertical position, that is, standing, essentially in a horizontal direction and the intersection line of this plane with the second section of the housing facing the body, will be projected then in a concave sense. In this way, a radius of curvature of 300 to 500 mm, especially from 300 to 400 mm, proved to be advantageous for at least segments.
    [0012] Furthermore, it may be advantageous that the second section of the housing, on its face facing the user's body, at least in certain regions, is concave in a horizontal plane and in a vertical plane. This can also facilitate, for example, the placement of the device in the user's waist region. For a concave conformation in a vertical plane, a minimum radius of curvature, per segment, from 500 to 900 mm, especially from 600 to 800 mm, especially from 700 to 800 mm, is advantageous.
    [0013] But, for example, it would also be possible to consider a modality in which the second section of the housing, on its side facing the body, is in a horizontal concave plane and in a vertical plane, in convex conformation by segments, so that altogether a saddle shape is realized.
    [0014] Notwithstanding the above, it may be advantageous that the second section of the housing, on its face facing the user, presents in an area remote from the positioning side of the device (that is, above) an inclined plane that away from the user's body, towards the first section of the housing. This mentioned inclined plane can advantageously be ergonomically rounded, but this is by no means a requirement. In this way, the device will support itself with a slightly smaller surface of the second housing section against the user's body, which allows the user to also bend his body over the device. Correspondingly, it can also be advantageous when the second section of the housing, on its side facing the user's body, in the passage of the side walls of the second housing section, or in the direction of the walls of the first housing section is chamfered.
    [0015] In view of a comfortable junction for the user of the first and second sections of the housing, it proves to be advantageous that the first and second sections of the housing, on their sides facing each other, present means of centering and the sections of the housing can essentially be joined in a reciprocal transverse direction, in relation to the dividing plane. The mentioned means of centering may randomly be formed eventually by elements in the form of pins or in a conical shape, or by regions of the housing protruding or recessed that especially can also be formed as blocks or as coffins and preferably cooperate in a complementary manner and with oblique planes encounter, reciprocally in a centralizing sense. Preferably, these centering means, that is, the reciprocally supported sides of the housing sections are so shaped that they can only be joined together in the correct way.
    [0016] To join the housing sections, it is advantageous that one section of the housing can be placed on top, easily and in an oblique way, towards the vertical, on a base of the other section of the housing, so that essentially it can be rotated transversely towards the dividing plane, leaning against the other section of the housing.
    [0017] It also proved to be advantageous that at the junction of the first and second sections of the housing, a vacuum communication between the container and the vacuum generator set is also simultaneously produced, so that the process of joining the whole becomes comfortable for the user and the user does not come into contact with bodily fluids. Correspondingly, this idea, in the release of the housing sections after use, acquires even greater importance.
    [0018] In order to keep the two sections of the housing securely touching, it is advantageous that they can be secured by means of locking or rear locking, quick-fit, normal-fit, or otherwise active, with closure due to the shape, and may be reciprocally separated.
    [0019] According to one embodiment of the invention, it proves to be advantageous that the rear locking or locking means protruding from the dividing plane of one of the housing sections and at the junction of the housing sections can be offset transversely towards the direction of the joints of the housing sections and can be moved to a rear locking position.
    [0020] The rear locking or locking means, in another embodiment of the invention, can be put in the release position by a manual control activation member. The hand-operated activation member can basically be located at a random point on the device. However, it proves to be advantageous that it is arranged on an upper side of the device, being specially shaped like a key that can be depressed. In this way it becomes possible for the device to be positioned on a preferably horizontal base and then the activation member can be successfully activated, without the device sliding to the side.
    [0021] To retain, suspend or manipulate the device as a whole and / or just one section of the housing or the other, it proves to be advantageous when one or the other section of the housing is conformed to a manual actuation, so that the device, or just the section of the corresponding accommodation, can thus be picked up and released from the other section of the accommodation. It proves to be especially advantageous that the second section of the housing for this purpose has an access hollow or a deep access section. This concavity of access or deep access section is preferably provided in the region of a manually operated activation organ for a rear locking or locking means, so that the user or a nurse with only one hand can unlock the second container section, separating it from the first container section. This access concavity or deep access section is preferably provided in an upper region and inclined in the direction of distance from the body and in the region of the second section of the accommodation, on the side facing the body of the second section of the accommodation. In this way, the user can perfectly, starting from the mobile operation, grasp the device with one hand and with the other hand he can loosen the fastening means, especially similar to a belt, as will be explained later.
    [0022] In view of the high positioning resistance of the device in stationary operation, or also in the temporary deposition of the device on a preferably flat surface, it proves to be advantageous when the device's gravity point (in a state not yet used in the container) is located in the lower half of the device, that is, below an imaginary horizontal central plane, at half the height of the device.
    [0023] In this sense, it also shows that it is advantageous that the ratio of a positioning face of the device in relation to its height is 4.0 - 6.0 cm2 / cm, especially 4.5 - 5.5 cm2 / cm. The positioning face of the device can be, for example, about 80 cm2 and its height, about 20 cm.
    [0024] It would be imaginable and advantageous for many uses that the positioning face of the device in the reciprocally united state of its two sections of the housing is precisely formed by these two sections. According to another embodiment of the invention, however, it proved to be sufficient that the positioning face of the device is formed only by the first section of the housing. To this end, it shows that it is advantageous that the first section of the housing has a region that stands out within a profiled recess of the first section of the housing that forms a part of the positioning face. This way, it is possible that the positioning resistance of the vacuum generator set is provided in an almost unchanged form also after the removal of the second section of the housing.
    [0025] According to another idea of the invention, it is proposed to shape the device in such a way that the first section of the housing starts to cover the second section of the housing, in the direction of frontal view on a viewing side away from the body of the first section of the housing. housing, preferably completely or at least 90% of the viewing face in this viewing direction. This again opens up other possibilities for shaping the second section of the housing at an advantageous price, because it can only be seen in a small part in the region of its side faces by the user or third parties, when the device is being used on the user's body. Therefore, the container no longer needs to be "hidden" in transport bags.
    [0026] According to an idea of the invention of special importance, it is proposed that the device be characterized, so to speak, in its entirety, in the form of several second housing sections, with a respective container that can be selectively joined to form the device with the first housing section, with the second housing sections and their containers varying in size, especially in the direction of depth, that is, in the direction of the user. In this way, different volumetric capacities can be offered by the different parts of the housing and its containers. In this case, housing sections can be provided that are adapted for mobile operation and those that are primarily intended for stationary operations, that is, especially of larger volumetric conformation, so that the containers for receiving liquids need to be replaced less frequently. .
    [0027] To avoid contamination and obstructions of the vacuum generator set, it proves to be advantageous that a filter is provided between the container and the vacuum generator set, which, especially with the container after use, is disposable.
    [0028] In addition, it shows that it is advantageous to have a set of level indicator for filling the container. This filling level indicator assembly can, for example, be realized by a sufficiently transparent conformation of a housing wall of the second section of the housing, or it can be formed in another random way, especially through electronic sensors and indicating means. In addition, it is advantageous to have a control set that, depending on the level of filling reached in the container, releases an alarm message. The container of the second section of the housing may contain a superabsorbent means for connecting the aspirated liquid and to prevent oscillation of the liquid.
    [0029] It has already been indicated that the finishing according to the invention of the device advantageously allows that on a viewing side of the first section of the housing, away from the body, control elements and switching elements are provided for the vacuum generator set . Advantageously, the control elements are shaped like a touch screen.
    [0030] According to an independent idea of the invention, it shows that it is advantageous that a tilt sensor is provided in the first section of the housing that, through a control set, in the case of a predetermined inclination of the first section of the housing, in the vertical direction, makes so that the indication is rotated on an indicator element preferably by 180 °, so that it can be read by the user from above. Starting from the normally vertical arrangement of the device, when it is being operated, for example, in a stationary regime, or if it is used by a standing user, in the so-called mobile operation, the user needs to tilt the device only up to a predetermined inclination, especially in 45 °, especially 40 °, especially 30 °, so that the indication of the indicator element (display) rotates and the user can read over the indication.
    [0031] According to another idea of the invention, of essential importance, it proves to be advantageous that essentially the entire viewing side of the first section of the housing, separated from the body, is formed or covered by a covering applied on the surface, so that they are leakage together with impurities collectors in the region of the control elements is avoided.
    [0032] Furthermore, it proved to be advantageous that in the first section of the housing there is an interface for data exchange, especially a USB interface, which is provided especially in the dividing plane, in the second section of the housing and in this way it is covered by second section of the housing, being especially protected against impurities. In this way, technical command information of the program can be transferred to an electronic command set of the device.
    [0033] The fastening means already mentioned for securing the device to the user's body for the so-called mobile operation of the device advantageously include a flexible segment in the form of straps or a belt or several of these segments, which can be attached at sides opposites of the first and / or the second housing section, in a separable way, and can therefore be separated for the stationary operation of the device of the respective housing sections. Regarding the fixing means, it can also be handles or splints that are positioned on the outside of the housing sections, in which other fixing means can be securely attached, for example, belt segments, straps, carriers, or similar units.
    [0034] Advantageously, the fixing means are integrated in a separable way between housing sections, reciprocally touching. They can be specially fitted in a gap between the opposite housing sections or in handles, splints or similar formations provided on the outside of the housing sections.
    [0035] The fixing means, preferably flexible, will preferably be applied around the circumference of the body, preferably in the region of the waist or basically also around the thighs, upper arms or chest, thus securing the device to the body. In a particularly preferred manner, the fastening means can be joined with the first and / or the second section of the device housing, similar to a quick lock, and are also separable. At their free ends, the fastening means can have fast closing means that can be fitted to the housing sections, especially elastic rear locking means, or handles that can be fitted or otherwise secured, in order to fix flexible fixing means. According to a preferred embodiment, the fixing means are disposed between the first and the second section of the housing, that is, on the dividing plane, between the housing sections, in a separable manner. An embodiment in which the fixing means can be reciprocally removed by separating the housing sections would be imaginable and advantageous. Or an advantageous embodiment would be imaginable, in which the separation of the fixing means is possible independently of a separation of the housing parts from one another. An additional shoulder strap or shoulder strap may also be provided, which alternatively or on an additional basis can be used with a waist belt. It can be detachable, for example, by means of a carbine-type clasp or by a fast, basically known and random clasp, in a handle or a splint in the housing sections, being fixed in a separable manner.
    [0036] In addition, it proves to be advantageous that the housing sections, in assembled state of the device, with the exception of the coupling for suction line or a washing or washing meter channel, and a possible access concavity or deep section of access, do not have rear locking components on the outside.
    [0037] The drawings show:
    [0038] figures from 1st to e - different views of a preferred modality of the device, according to the invention, used on the body, to provide flow for clinical uses;
    [0039] figures 2a through e - different views of a vacuum generator set and the first section of the housing that includes the control components, relative to the device according to figure 1;
    [0040] figures 3a to i - different views of a second section of the housing of the device of figure 1 that forms a container for receiving bodily liquids;
    [0041] figures 4a to e - views corresponding to figures 1a to and of another embodiment of the device of the invention, the second section of the housing having larger dimensions than in the device according to figures 1a to e; and
    [0042] figure 5 - sectional view by the device in the region of the vacuum communication between the first and the second section of the housing; and
    [0043] figures 6, 7 - a view of the second section of the housing of the devices of figures 1 and 4 below, to demonstrate the different positioning faces of these second housing sections.
    [0044] Figures 1a to e show a first embodiment of a portable device 2, according to the invention, to provide vacuum for clinical purposes. The device comprises a first housing section 4, in which a vacuum generator set in the form of an air pump is integrated, as well as electrical and electronic control components for the device as a whole, including batteries or preferably rechargeable batteries. A charge coupling for the batteries is designated with the reference number 6. In addition, the device 2 comprises a second housing section 8 which, if preferred, also forms a container 10 for receiving bodily fluids, especially for receiving segregations of injuries. aspirated from an injury. Preferably, the entire second section of the housing 8 is shaped like a disposable product. In its upper region, a coupling sleeve 12 is provided for a suction line not shown, which then, for example, when using device 2 for vacuum wound therapy, leads to a dressing that seals the pressure-tight wound where, for example, through a mouth it communicates with the wound compartment itself, so that in this compartment apply a vacuum and preserve this vacuum and aspirate segregation of the wound into the container 10. For that, container 10 communicates with the vacuum generator set. In addition, it is represented with connection 13 for an optional measuring or washing channel, which, like the suction line, leads to the wound. This coupling transfixes the second section of the housing 8 and empties into the first section of the housing 4, from which the measuring or washing channel, for example, can be subjected with air as a washing medium and / or can be detected and evaluated pressure in this gauge or flush channel.
    [0045] According to the invention, the housing sections 4 and 8 abut reciprocally through a dividing plane 14, essentially vertical, indicated in several figures. When the device 2, as indicated in figure 1a is positioned on a flat and horizontal base 16, then the dividing plane 14 will essentially be oriented in a vertical direction. This means that the two sections of the housing 4, 8 are not reciprocally interlocked or stacked on top of each other, but are now positioned adjacent in the united state of the device 2, depending on their destination. The expression of dividing plane 14 must therefore not be understood in the sense that it is necessary to deal with a plane geometric plane, which is immediately visible from figures 2a to e, which show the first section of housing 4 in different views . It can be immediately recognized that side 18 of the first section of the housing 4, facing the second section of the housing 8, is by no means flat, but it is shaped like a variety of elements that stand out towards the second section of the housing 8. Side 20 of the second section of housing 8, facing the first section of housing 4, is essentially complementary to the conformation of side 18 of the first section of housing 4, so that both sections of housing 4, 8 can only be properly secured to each other. The two housing sections 4, 8 as a whole are formed in a discoidal direction, that is, their width b, in the horizontal direction and their height h, in the vertical direction, are greater than their horizontal and vertical depth T towards the projection of the width. In this way, it becomes possible that the device 2, in the direction of the depth as a whole can be so shaped and dimensioned that it can be used comfortably in the user's body. According to the invention, the device 2 is so shaped that the parts of the container 4, 8, provided side by side, can be positioned in such a way in the body that the second section of the container 8 is now positioned facing the body, that is, between the body and the first section of the housing 4, and the first section of the housing 4 is now positioned away from the body, that is, essentially forming the visible side of the device 2. Therefore, the side 22 of the second section of housing 8, facing the user's body, has a rounded shape. As can be seen from Figures 1c, 1b, 3f, 3e, the side 22 facing the body, in section and considered horizontal, has a concave conformation and covers, in the exemplified part shown, by segments, a radius of curvature R, for example, 368 mm (figures 1c, 3f). In addition, side 22, facing the body, considered in section with the vertical plane, also has a concave shape, where it has a radius of curvature R, for example, 750 mm (figure 1 d). In this way, device 2 can be packaged and used ergonomically around a user's waist.
    [0046] Furthermore, it can be recognized that the second section of the housing 8, on its face 22 facing the body, in an upper and also lateral region, presents the inclined plane 24 that moves away from the user's body, projecting in the direction of the first section of the housing 4, that is, in the direction of the side walls 26 or it covers a frontal side, circumferential of the discoidal shape of the second section of the housing 8. The inclined section 24, in the case shown and shown, is shaped around; from positioning side 28 it extends from the bottom upwards where it projects in an arcuate way to the other side, and then goes down to the positioning side 28, in a return movement.
    [0047] Furthermore, it can be seen from figures 1d and 3, that on the side 22 facing the body of the second section of the housing 8, a deep access section 30 is formed, in the form of an opening that transfixes the second housing section 8 and in a region of the second section of the upper housing 8 and generally inclined towards the body. In this way, the device 2 as a whole or just its second section of the housing 8, can be picked up and handled with one hand.
    [0048] In the preferred mode shown, next to this access concavity 30, on a top side of the device 2, a control unit 32 of manual operation is provided, for example, in the form of a key, which acts on a locking means or rear locking 34 (see figures 2b and 2d). In the joined state of the two sections of the housing 4 and 8 there is a rear locking or locking means 34, in a blocked state that keeps the two sections of the housing 4, 8 closed due to shape, applied reciprocally. Only with activation of the activation member 32 will the lock be released, so that the sections of the housing 4.8 can be separated from each other. Due to the arrangement and conformation of the penetration concavity 30 and the manually operated control member 32, spatially close in a reciprocal direction, and in such a way that a user can both penetrate the access concavity 30 as well as with a finger of the same hand , at the same time, the activating organ 32, being thus the command of only one hand to release the second section of the housing 8, of the first section of the housing 4. This proves to be especially advantageous, because in this case, a the second section of housing 8, filled with bodily fluids, can be separated with just one hand and moved to a disposal container.
    [0049] To join the two sections of housing 4, 8, the second section of housing 8 will be slightly, in an oblique direction, applied from behind and above with its bottom edge on two pins 33 (figure 2), forming a point of rotation and belonging to the first section of the housing 4. In the second section of the housing for these purposes, a cut-out region 35 is provided at the bottom edge (figure 3a) to receive pin 33. When pin 33 and cut out region 35 are mutually meshed , then the second section of the housing 8 can be rotated against the first section of the housing 4. In this way, the faces 18 and 20, facing each other, will be applied against each other and thus reach in one movement of self-centering (reinforced by other means of guidance or centering 37 (figures 2d) and 39 (figure 3a) and by the complementary conformation of the sides 18, 20, facing each other, of the housing sections 4, 8) reach your d position estino. By moving the two sections of the housing 4, 8 in a reciprocal approach, especially in an essential way, in a transverse direction towards the vertical dividing plane, a rear locking or locking means 34 will be automatically deflected and will then snap into position that blocks housing sections 4, 8, reciprocally. For this purpose, a second hook 41 (figure 3i) is provided in the second housing section 8 (figure 3i) which is captured from below by the rear locking or locking means 34. When the housing sections 4, 8 are moved to their locked position then a vacuum communication will automatically be produced between the interior of the container 10 of the second section of the housing 8 and the vacuum generator set, by means of coupling means 36 (described later in connection with figure 5).
    [0050] A viewing side 38, removed from the body, belonging to the first section of housing 4, is slightly tilted in the direction of the vertical plane, so that the discoidal shape narrows in an upward direction. In this way, easier viewing is provided for the viewing side 38. There are control elements 40 and indicator elements 42 there, especially in the form of a touch screen. Essentially, the entire viewing side 38 is covered or formed by a cover 44, applied to the surface, so that in the region of the control elements 40, no impurity collecting cracks are formed.
    [0051] In addition, in the region of the dividing plane 14, the figures show between the housing sections 4, 8 reciprocally supported, a locking slot 46 for fixing by locking, separately, of a fixing means, especially and preferably in the form of a flexible belt or a strap, or a splint where, for example, the belt or a shoulder strap can be attached or otherwise. It shows that it is advantageous that this fixation means can be separated from the housing sections 4, 8 and, therefore, does not create interference when the device 2, in stationary operation, that is, preferably positioned on a flat base 16, is eventually used when a patient to be treated with the equipment is resting on a bed. In figure 2d, on side 18 of the first section of housing 4, means 48 are indicated, in which the fastening means fitted in the slot 47 can be secured or retained.
    [0052] The other embodiment shown in figures 4a to and from the device of the invention differs from the embodiment of figure 3 in that the second section of the housing 8 and the container 10 formed by it, are formed in a larger volume. The inclined section, that is, the chamfer, in the upper region of the side 22 facing the body of the second section of the housing 8, where the access concave 30 is formed, is inclined even more sharply in the direction of the body's distance from the user. In this way, even better access is possible. This second section of the larger housing 8 is more suitable for stationary operation of the device 2; to this end, it could also have a side 22 which is convexly arched to the outside, or it could be shaped even more inclined than shown in figures 4.
    [0053] Figure 5 shows in detail the conformation of the vacuum communication between the interior of the second section of the housing 8 that forms the container 10 and the first section of the housing 4. The suction side of a vacuum generator set, not shown, leads to the conical coupling means 36 which conically narrow in the direction of the second housing section 8. In this way, against the conical coupling means 36 of the first housing section 4, a coupling means could be applied sealingly conversely 50, at least somewhat flexible and belonging to the second section of the housing 8, which, in the exemplified case shown, has a circular opening 52 which is limited by a flexible sealing side 54. This opposite coupling means 50 flows into the second housing section 8. It is simultaneously the filter receiving means 56 for a filter 58 which in the case presented as an example is shaped like a trough-shaped filter and prevents bacteria from being sucked in. of the first housing section 4. It can be perfectly recognized that when moving, in the direction of reciprocal approximation of the two housing sections 4, 8, the coupling half 36 of the first housing section 4 forms with the opposite coupling half 50 of the second section of the housing 8 a pressure communication facing the outside.
    [0054] Similarly, the connection between the coupling 13 for a measuring and washing channel and a coupling half 60, also shaped, for example, conically, is configured in the first section of the housing 4. How can to be verified from figure 3g, in the passage opening 62, in the second section of the housing 8 a coupling or housing section can be integrated which would then form the coupling 13 shown in figure 1d for the measuring or washing channel. This coupling or housing section not shown can then be coupled to a pressure seal with the conical coupling half 60. In this way, through a line, a fluid medium, especially air or washing liquid, can be conducted to the wound, in order to reinforce the suction of segregations from the wound. Typically, a measuring or washing set and the suction line are disposable belongings in relation to the second section of the housing; will be discarded with them after use.
    [0055] Finally, figures 6 and 7 show positioning faces 64 of variable size (about 7 cm2) and 66 (about 55 cm2) in the second housing sections 8 of different size, according to the figures 1 and 4. The housing sections 8 can be positioned with these positioning faces 64, 66 on a base when they are away from the first section of the housing 4. When they are attached to the first section of the housing 4, the positioning face of the device 2 is formed by the first housing section 4. In the positioning faces of the housing sections 4, 8, feet can also be provided, as can be seen in figures 1b, 2b, 4b.
