    [0001] The present invention relates to a device for administering fluid or substances for ENT. It is, in particular, intended for the decluttering, hygiene, irrigation and treatment of nasal passages.
    [0002] European Patent No. 2389918 discloses a device delivering a liquid in a first nostril while taking it in the other through the mobilization of a separation means which can be constituted by the piston of a syringe or by a deformable membrane . To work perfectly, it is necessary, however, to obtain an excellent seal at each nostril. Indeed, the device operates in closed circuit, that is to say it generates a movement of liquid in the ENT sphere allowing, probably by a phenomenon of surface tension at the level of the soft palate, to prevent that the liquid does not enter the throat, when the anatomy of the rhino-pharynx is favorable, in other words when the diameter of passage does not exceed about 7 mm, which is the case of children, but also of a majority of adult depending on the position of the soft palate. On the other hand, if the nasal tips allow an air inlet, the phenomenon is no longer observed and there is a risk of liquid penetration into the throat of the patient, or even false route. Of course, the profile of the nasal entries varies according to the individual. Differentiation parameters are numerous and linked, for example, to age, sex, racial type, etc. Nevertheless, we can retain as main: the diameter of the nostrils, their spacing, as well as the angle of inclination of the inner face of the wings of the nose. It is very difficult to obtain a tight and simultaneous connection with the two nostrils of a patient whose morphological characteristics are unknown. It is also important that this seal can be obtained effortlessly and quickly. The invention aims to overcome these constraints by providing a device adapted to adapt to the largest number of patients. The invention uses the means of the known devices, namely: - a delivery circuit intended to be connected in a sealed manner via a first nosepiece to a nostril and able to contain a fluid or substances, - a sampling circuit intended to be connected sealingly via a second nosepiece to the second nostril and adapted to collect a fluid or substances, a separation means mobilized by the user, able on the one hand to create a leaktight separation between the administration circuit and the sampling circuit, and able on the other hand to generate simultaneously in each circuit a movement of fluid, the device according to the invention further comprises at least one conduit, consisting of a material provided with elastic and / or deformable properties, able to allow the adjustment of the angular difference between the two nasal tips so that it promotes the sealing of each circuit with the nose of u patient. Thus, the connecting means of the device to the patient's nose can be adapted to its profile to promote a good seal.
    [0003] In one embodiment, the outer face of the delivery duct and / or the outer face of the sampling duct has an inclination angle with respect to the vertical of between 00 and 60 °. This configuration provides rapid positioning of nasal tips at an angle corresponding to that of the entrances of the nostrils.
    [0004] In a preferred embodiment of the invention, the external face of the administration or sampling duct has an angle of inclination with respect to the vertical greater than that of the internal face. Thus, the method of manufacturing the device is simplified because the injection mold does not require a drawer, the mold release of the conduits being carried out naturally.
    [0005] In an alternative embodiment, at least one of the ducts is made of a material or a profile able to give it a shape memory. This configuration has the advantage of being able to maintain a position of the nasal tips corresponding to the morphology of the patient. Other features and advantages of the invention will emerge from the description which follows with reference to the accompanying drawing, schematically showing several embodiments, in longitudinal section, and in which Figure 1 illustrates the consequences of poor sealing at the level of the nostrils; Figure 2 illustrates a satisfactory positioning of the tips at the nose; Figure 3 shows a possibility of adjusting the position of the nasal tips by acting on the deformation capacity of the device; FIG. 4 illustrates a preferred embodiment with ducts whose inclination of the external face is greater than that of the internal face; Figure 5 is a partial view of the device showing the possibility of changing the spacing distance between the two nosepieces by acting on the length of their connection; Figures 6a and 6b illustrate another possibility of acting on the spacing distance between the ducts; FIG. 7 shows an embodiment in which the administration duct comprises an indexing means. In the following description, the term user refers to the person who actuates the device while the term patient refers to the care recipient when it comes, for example; a phlegm extractor. The device is primarily intended for the administration of liquid solutions. However all types of fluids or substances compatible with the mode of operation can be used.
    [0006] FIG. 1 illustrates the difficulty of obtaining the tightness around the nostrils of the patient with the device described in patent EP 2389918 if we do not take into account the inclination given by the wings of the nose referenced 1. In fact, in introducing a nosepiece vertically into the nose, the wings are deformed thereby creating an air intake which, on the one hand lets out liquid on the lips and on the other hand, by canceling the operation in a closed circuit, increases the risk of liquid penetration into the throat. Figure 2 shows that when the nasal tips are introduced obliquely in the nes 1, the seal is much easier to achieve. It should be noted, however, that these will preferably be flexible. Indeed, if the seal is obtained easily with a rigid nosepiece by deforming only one nostril, however the introduction of a nosepiece not deformed 11th simultaneously in each nostril is favorable to the creation of leaks, mainly in the central part of the nose which can not absorb this double constraint. FIG. 3 shows the device constituted by a syringe of cylindrical shape comprising a delivery circuit 100, a sampling circuit 200 and a separation means 300. The delivery circuit 100 comprises a delivery chamber 104 forming a the body of the cylinder reserve lOg able to contain a fluid or substances, in this case a liquid. This chamber is sealingly connected, in its upper part, to a first nostril of the patient by a delivery duct 106, inclined relative to the vertical by an angle between 0 ° and 60 °, and by a nosepiece 401 preferably deformable. The cylinder body also comprises a collection chamber 204 forming a collection reservoir 203 capable of collecting the liquid or substances, for example mucus; from the nasal fossae. The collection chamber 204 is sealingly connected to the second nostril via a sampling conduit 206 and a nosepiece. 401, preferably deformable Pile also comprises a gripping means 205, such as lateral wings, intended to allow the positioning of the fingers of the user. The sampling duct 206 has freedom of movement or deformation with respect to the delivery circuit 100; for example because of its constitution viscoelastic material, so that it is possible to vary the angular distance a between the two nosepieces 401. As an indication the angular difference a may vary between 1 'and 60 °: 1, e means of separation. 300 meanwhile comprises a mechanical means, such as a piston 307 adapted to the profile of the cylinder body, adapted to ensure sealing between the delivery circuit 100 and the pre-test circuit 200, Le. piston 307 is secured to a rod 304 provided with a gripping member 306 for allowing the support of the thumb of the user. The rod 304 cooperates with a sealing means 305, such as a bearing positioned in the bottom wall of the collection chamber 204; and thanks to which she can slide there. waterproof. The user introduces the liquid into the delivery chamber 104, for example by pulling on the gripping element 306 so that the piston 307 generates a depression, In order to adapt to the profile of the nostrils of the patient, the user exerts a force on the sampling conduit 206 to bring the two nosepieces 401, which also changes the angular difference ri .; and introducing them into the nostrils: When the sampling conduit 206 is released, and because of its elastic properties, it allows the nasal tips 401 to exert a slight pressure on the inside of the nostrils, which improves both their retention in position and their tightness. Ensuitee. the user places the index and the middle finger on the gripping means 205, the thumb on the gripping element 306 and exerts a thrust on the piston 307 so that it administers the liquid in a first nostril while the aspirant in the other at the same flow, thus removing any mucus present in the ENT sphere. It will be noted that the conduit 206, at least in part, may consist of a material provided with a shape memory able to maintain its position, of course, any element, mechanical or otherwise, capable of allowing the variation of the degree of inclination conduit 206 relative to the rest of the device can be used, such as a sealed connection ball otherwise known. FIG. 4 illustrates a preferred embodiment of the device with the particularity that only the external and terminal face of each conduit, the administration conduit 106 and the sampling conduit 206 is oblique while the internal face is straight, or with an inclination less corresponding for example to the value of the draft of a plastic injection mold, usually between 0.1 ° and 5 °. The external face of the administration duct or the sampling duct therefore comprises an inclination angle f3, between 0 ° and 60 ° with respect to the vertical, greater than the clearance angle y of the internal face, between 0.1 ° and 5 °. With a profile of this kind, it is possible to unmold the two ducts naturally, which greatly reduces the tooling costs, while maintaining the inclination necessary to facilitate the tight positioning of each nosepiece 401 in the nostrils. Each nasal endpiece 401 is connected to the device via a connecting conduit 402, the assembly constituting a nasal connection means 400. When placed on the delivery conduit 106 or on the sampling conduit 206, the connecting ducts 402 conform to their inclination. Thus, because of the difference in inclination between the outer and inner face of each duct 106 or 206, the greater the insertion length of the corresponding connecting duct 402, the lower the angular difference a will be high. The connecting ducts 402 are preferably made of viscoelastic material thus giving them flexibility so as to be able to act, bringing them together or deforming them, also on the angular spacing a and thus benefit from the spring effect due to the material and allow nasal tips 401 to exert pressure within the nostrils. Of course, if the two faces of the ducts 106 or 206 each have an inclination identical to the vertical, the angular deviation a will no longer depend on the insertion length but only the deformation provided on the connecting duct 402. Note that the flexibility of each connecting conduit 402 gives the nosepiece 401 on which it is connected a possibility of inclination between these two elements.
    [0007] It will also be appreciated that the length of the connecting conduit 402 is an important parameter. Indeed, an insufficient length does not provide the necessary flexibility for the adaptation to the profile of the nostrils whereas an excessive length is detrimental to the maintenance in position by lack of rigidity: 5 Figure 5 illustrates the fact that to act on the insertion length of the connecting ducts 402 on the conduits 106 and 206, respectively of administration and sampling, also makes it possible to act on the spacing T) of the nasal nozzles 401 in order to adapt to the dimensional variations of the columella. Indeed, the greater the insertion length, the greater the spacing D between the two nosepieces 401 10 will be high: Figure 6a illustrates a configuration in whichthe spacing between the two nosepieces 401 is effected by the adjusting the distance between the delivery conduit 106 and the withdrawal conduit 206, for this purpose; the delivery conduit 106 includes a cover 106b for sealing the reservoir 108 while providing the possibility of pivoting about the cylinder body corresponding to the. administration chamber 104, the administration duct 106 comprises a delivery nozzle 106a vertically and eccentrically positioned on the upper face of the lid 106b. Note that this configuration allows a filling of the device directly in the. 10g reserve, the connecting conduits 402 are flexible in order to be inclined. It will also be appreciated that the cover 106b could be on the pickup circuit 200 to perform the gap adjustment function in a similar manner. As shown in FIG. 6b, by rotating the cover 106b, it is possible to act on the distance between the ducts 106 and 206 respectively 25 administration and sampling and therefore on that of nasal tips 401. Figure 7 illustrates a variant in which the lid 106b is provided with a corresponding cut 111 the profile of at least one positioning pin 112 integral with the administration chamber 104, the latter two elements constituting an indexing means 110. Of course, there can be several indexing positions: indexing, the establishment of the cover 106b is performed without possibility of error and allows optimal positioning of the nasal tips 401 relative to the rest of the device The delivery conduit 106, the sampling duct 206 and the connecting ducts 402 may consist of a material having a shape memory, a reinforcement, a rigidity or else an otherwise known corrugated profile allowing these ducts to maintain their spatial position and / or Tele length after the effort destined to deform them has ceased. The administration duct 106 and / or the sampling duct 206 may be assembled so as to be movable relative to the rest of the device> for example to facilitate the cleaning operations. It follows from the foregoing that the device according to the invention is intended to facilitate its tight positioning in the nostrils of the patient which, when this characteristic is obtained, makes it particularly interesting for use in young children.
