    专利说明:

    [0001] The invention concerns a connector for a liquid circuit, especially for medical use.
    [0002] EP 0 544 581 discloses said secure connector which includes a female Luer type distal entry cone to be connected to a device having a compatible and complementary male Luer type connector. The distal entrance cone is sealed by a septum or membrane that has a level surface that is easily cleaned to eliminate germs or bacteria before making a possible connection. The septum protects a tube that, once made the connection, partly extends into the hole of the male Luer connector that is connected to it. Once connected, the connector of EP 0 544 581 has a straight tubular passage and a reduced dead volume. EP 0 544 581 describes a secure female connector.
    [0003] However, it is necessary to have a male connector that has the same properties in order to obtain the same safety benefits resulting from the use of the female connector of EP 0 544 581. On the other hand, the use of said male secure connector would allow , together with the connector of the document EP 0 544 581, practice a safe universal connection.
    [0004] Therefore, in French patent application No. FR 2 931 363, a connector for a liquid circuit, especially for medical use, was suggested, comprising a proximal coupler, a distal coupler defining a passage, a hollow tube mounted fixedly in the proximal coupler, extending into the passage of the distal coupler and including a distal free end, and an elastically deformable, substantially tubular membrane, closed at a distal end by a membrane thickness and intended to cover the free end of the hollow tube substantially watertight at rest, the distal coupler being slidably mounted to the proximal coupler between a distal resting position and a proximal use position in which the hollow tube can be selectively detached from said membrane thickness.
    [0005] The use of said distal coupler slidably mounted to the proximal coupler allows especially to detach the distal free end of the hollow tube protected by the membrane for cleaning and elimination of all germs or bacteria before connection, the hollow tube performing the function of male part of the connector.
    [0006] However, the Depositor realized that the male and female connectors were difficult to clean, especially their respective distal parts, including the membrane. Now, especially in the field of chemotherapy, where medications are very aggressive both at the time of preparation by the team and at the time of injection in patients, the property of the material used is fundamental, since patients are extremely sensitive to nosocomial diseases.
    [0007] In addition, the connection and disconnection of the connector set are complex and require the operator to perform several steps.
    [0008] Finally, the current locking means do not guarantee the user that the connectors are effectively well connected. In particular, when threads are used on the ends of the male and female connectors that are to be connected, the operator is often unable to know whether the connectors have sufficiently screwed together and whether the pipes have been connected correctly.
    [0009] The purpose of the invention, therefore, is to suggest an improvement for the male and female connection.
    [0010] For this purpose, the invention proposes a safe connection set for a liquid circuit comprising:
    [0011] - a male connector and a female connector, each comprising a proximal coupler and a distal coupler,
    [0012] - the distal coupler of each of the connectors defining a passage and comprising a tubular part, in which a connecting member fixedly mounted on the proximal coupler extends coaxially, and an elastically deformable, substantially tubular, closed membrane at a distal end by a membrane thickness and movable between a position downstream of the seal, in which the membrane watertightly covers a free end of the connection member, and a position upstream of the connection, in which the membrane is crossed by connecting member,
    [0013] in which the tubular part of the distal coupler of the male connector is adapted to be inserted, during a connection, in the tubular part of the distal coupler of the female connector, and which, in the downstream position of the seal, for each of the male connectors and female, the membrane watertight seals the passage of the distal coupler.
    [0014] Certain preferential aspects, however not limiting the connection set according to the invention, are the following:
    [0015] - the external surface of the tubular part of the female connector is devoid of threads,
    [0016] - the outer surface of the tubular part of the male connector comprises a thread in order to constitute a connectable "Luer-Lock" type inlet,
    [0017] - the male connecting member and the female connecting member are hollow tubes, and the hollow tube of the male connector is adapted to be inserted into the hollow tube of the female connector,
    [0018] - the outer surface of the tubular part of the distal coupler of each male and female connector is smooth and of axial section invariable in a substantially continuous part and includes a retention means extended transversely, said surface and said retention means forming a male or female locking means,
    [0019] - the retaining means of the male locking means comprises at least one pin extended transversely from the smooth surface in relation to the longitudinal axis of the coupler,
    [0020] - the male locking means includes two pins extended on both sides of the coupler, in opposite directions,
    [0021] - the retaining means of the female locking means comprises at least one groove formed on the surface of a collar ("collerette") and intended to receive the pin of the male locking means,
    [0022] - the groove is curved,
    [0023] - the collar partially extends over the coupler,
    [0024] - the threads extend over the surface of the tube that is not covered by the collar,
    [0025] - the necklace is drilled at a proximal end,
    [0026] - the membrane includes a gap in the thickness of the membrane arranged to be crossed by the connection member positioned upstream of the connection.
    [0027] In accordance with a second aspect, the invention suggests the use of a set according to any one of claims 1 to 13, comprising the steps of:
    [0028] - clean the membrane;
    [0029] - position the proximal ends of the male and female connectors, so that their respective membranes are in contact and that the two connectors had their longitudinal axes together, in order to create a watertight junction of the two connectors;
    [0030] - insert the male connector into the female connector, so that the connection member of the male connector is connected to the connection member of the female connector; and
    [0031] - lock the set.
    [0032] The connector for a liquid circuit, especially for medical use and featuring a longitudinal axis comprises:
    [0033] - a proximal coupler;
    [0034] - a distal coupler defining an extended passage along the longitudinal axis;
    [0035] - a hollow tube fixedly mounted on the proximal coupler, extended in the passage of the distal coupler and including a distal free end; and
    [0036] - an elastically deformable membrane, substantially tubular, closed at a distal end by a thickness of membrane and intended to cover the free end of the hollow tube in a substantially watertight manner at rest,
    [0037] in which the surface of the distal coupler is smooth and of axial section invariable in a substantially continuous part of the distal coupler and includes a retention means extended transversely, said smooth surface and said retention means forming a male locking means or female.
    [0038] Certain preferred, but not limiting, aspects of the connector are:
    [0039] - the retaining means of the male locking means comprises at least one pin extended transversely from the smooth surface in relation to the longitudinal axis of the distal coupler;
    [0040] - the male locking means includes two pins extended on both sides of the distal coupler, in opposite directions;
    [0041] - the retaining means of the female locking means comprises at least one groove formed on the surface of a collar and intended to receive the pin of the male locking means;
    [0042] - the groove is curved;
    [0043] - the end of the groove serving as a stop for the pin includes a recess forming a retention of the pin in a locked position;
    [0044] - the collar extends only over part of the distal coupler; and
    [0045] - a central part of the distal coupler not covered by the collar comprises threads in order to constitute a pluggable "Luer-Lock" type input.
    [0046] A set of at least two connectors similar to the previous ones, intended to cooperate together to make a fluid circuit, especially in the medical field, is characterized by the fact that the locking means of one of the connectors is male, and the locking means of the other connector is female.
    [0047] Certain preferential aspects, but not limiting a set, are the following:
    [0048] - one of the locking means includes at least one pin extended transversely from the smooth surface in relation to the longitudinal axis of the distal coupler; and
    [0049] - the other locking means includes a smooth surface (260) on which at least one curved groove is formed to receive the pin of the first locking means
    [0050] - the smooth surface from which the pin extends is the external surface of the distal coupler of the male locking means; and
    [0051] - the smooth surface on which the groove is formed is the internal surface of a collar disposed on the distal end of the female locking means;
    [0052] - the width of the groove is approximately equal to the diameter of the pin taken in a direction transversal to a direction of insertion of the pin in the groove, and the length of the groove is approximately equal to the relative distance traveled by the connectors when they are coupled; and
    [0053] - the distal couplers of the two connectors are structurally similar, except their respective locking means, their respective membranes are flush with the distal ends of said distal couplers so that the coupling / uncoupling of the male connector and the female connector is carried out in a single axial movement.
    [0054] A use of said set comprises the following steps of:
    [0055] - clean the membrane and the respective means of locking the connectors;
    [0056] - position the distal ends of the connectors, so that their respective membranes are in contact and that the two connectors have their longitudinal axes together, to create a watertight junction of the two connectors;
    [0057] - position the connectors at an angle, so that at least one pin is arranged in the longitudinal axis of the corresponding groove;
    [0058] - support the two connectors against each other until the pin touches the end of the groove; and
    [0059] - rotate the connectors relatively to each other in order to lock the pin into the groove.

    [0071] Referring to Figures 1 to 2, a female connector 100 according to the invention will be described.
    [0072] The female connector 100 includes a proximal coupler 120, an elastically deformable, substantially tubular membrane 130, and a distal coupler 140.
    [0073] The shape of the proximal coupler 120 is generally tubular and includes a proximal end comprising, in this case, a female "Luer-Lock" type pluggable entry 121. As an alternative, this pluggable input 121 is of the male "Luer-Lock" type. It extends, in the distal direction, through a hollow body 122 that includes, in the vicinity of the proximal end, a projected annular expansion 126 that extends in a radially external circumference of the hollow body 122 of the proximal coupler 120, designed to cooperate with a complementary annular groove 142 provided in the distal coupler 140, in order to block the proximal 120 and distal 140 couplers in translation in relation to each other, as will be seen below. The hollow body 122 of the proximal coupler 120 ends, in the distal direction, in a ring 123 of circular shape, topped coaxially by a hollow tube 124 that extends as a projection of the proximal coupler 120 in the distal direction. The hollow tube 124 ends at a distal free end 125. The hollow tube forms a connecting member. The distal coupler 140 is tubular in shape and defines a passage 141.
    [0074] As an alternative, the proximal coupler 120 includes at least one perforation, preferably two, which cooperate with the same number of holes provided in the distal coupler 140.
    [0075] At this point, membrane 130 of connector 100 will be described in detail.
    [0076] The membrane 130 includes elastic means 131, in this case a spring 131, for example, of the helical compression spring type, forming a membrane body, extending to a distal end 132 closed by a membrane thickness. The elastic means 131 serves to support the proximal coupler 120 and to push the distal end 132 of the membrane so that the latter reaches a stable position downstream of the seal of a distal end of the passage 141.
    [0077] Alternatively, the body of the membrane 130 is wavy, and in the form of a bellows.
    [0078] In the thickness of the membrane, a slit 133 is made which crosses said thickness of the membrane.
    [0079] Optionally, in a radially external circumference, the distal end 132 of the membrane 130 has a groove intended to receive a means of reinforcement / constriction 134, here presenting itself in the form of a cup, which surrounds the gap 133 and which guarantees, in a rest position, that it is closed again in a watertight manner to avoid any pressurized fluid losses that may be present inside the hollow tube 124 during the use of connector 100 mounted on a fluid circuit.
    [0080] In addition, the particular shape of the body 131 of membrane 130 gives the latter the ability to undergo elastic deformation in the longitudinal direction and to act as a return spring, allowing the membrane 130 to resume its initial resting form, as illustrated in Figures 1 and 2, during disconnection of connector 100.
    [0081] In this way, the female connector 100 includes a membrane 130 which is confined to the tubular part of the distal coupler 140. This allows, in addition, in the stable position downstream of the seal, a radial tightening of the membrane 130, and in particular of the distal end 132 of the latter, realized by a wall of the tubular part of the distal coupler 140: a better tightness and constancy in the counter pressure are thus obtained.
    [0082] The membrane 130 is produced in elastomeric material, such as polyisoprene, silicone, or even an elastomeric thermoplastic (TPE).
    [0083] During assembly, the spring 131 that forms the body of the membrane 130 is inserted into the hollow tube 124 of the proximal coupler 120.
    [0084] In its periphery, preferably in the proximal part, the distal coupler 140 includes a locking means 150 male or female. The locking means 150 will be described in more detail below.
    [0085] The distal coupler 140 additionally includes the manipulation means 143 of the connector 100. In this case, there are two and extend radially as a centrifugal projection on both sides of the distal coupler 140. The manipulation means 143 allows to hold firmly connector 100 when connecting to a male connector.
    [0086] During assembly, the distal coupler 140 is mounted on the proximal coupler 120 so that the annular projection 126 is positioned in the corresponding annular groove 142. The distal coupler 140 is then fixed according to the usual processes in the proximal coupler 120, for example, by gluing their respective contact surfaces, in order to obtain a monobloc sump, or by ultrasound welding.
    [0087] A male connector 200 according to the invention will now be described.
    [0088] Referring to Figures 3a, 3b, 4a and 4b, a male connector 200 includes a proximal coupler 210 and a housing 220 mounted on the proximal coupler 210. The installation of the housing 220 on the proximal coupler 210 allows to delimit a substantially tubular compartment 211 that forms a passage. The proximal coupler 210 includes a pluggable input 212, here, of the male "Luer-Lock" type. As an alternative, pluggable input 212 is of the "female Luer-Lock" type. Connected to the proximal coupler 210, the connector 200 includes a connecting member 213, here in the form of a hollow tube 213, extended in the substantially tubular passage 211 in the distal direction.
    [0089] The crankcase 220 is formed by a distal coupler 240 and includes a tubular part.
    [0090] The proximal coupler includes a membrane or septum 230 that comprises a slit 233 in its thickness. Slit 233 is substantially perpendicular to a longitudinal axis of connector 200.
    [0091] The connector 200 finally includes the elastic means 231, in this case a spring 231, for example, of the type of helical compression spring, but which can take any other form also known to the person skilled in the art. The spring 231 rests on the proximal coupler 210 and pushes the septum 230 in such a way that the latter reaches a stable position downstream of the seal of a distal end of the passage 211.
    [0092] A more detailed description of a connector similar to connector 200 is provided in document EP 0 544 581, which can be consulted for this purpose.
    [0093] The septum 230, in this case, is an elastomeric membrane in general in the form of a cylinder of revolution that includes a slit 233 substantially flat and perpendicular to a longitudinal axis of the septum 230. Slit 233 extends from a surface downstream to an upstream opening, substantially in the form of a revolution cylinder, designed to watertightly receive a free end of the hollow tube 214.
    [0094] The septum 230 is mounted on a rigid cup 234 forming the means of reinforcement / constriction. As an alternative, the cup is surmounted by an elastically deformable ring, forming part of reinforcement / constriction means.
    [0095] A more detailed description of reinforcement / constriction means 234 is provided in document FR 2 929 123, which can be consulted for this purpose.
    [0096] In this way, the male connector 200 includes a septum (or membrane) 230 that is confined in the tubular part of the distal coupler 240. This also allows, in the stable position downstream of the seal, a radial tightening of the septum 230, and in particular of the slit 233 of the latter, made by a wall of the tubular part of the distal coupler 240: better tightness and constancy in back pressure are obtained.
    [0097] In its periphery, preferably at a distal end, the distal coupler 240 includes a locking means 250 female or male.
    [0098] Continuing the description, the embodiment according to which the female connector 100 includes a male bayonet locking means will be described in more detail, while the male connector 200 includes a female bayonet locking means. This in no way reflects a limitation, as the consistent embodiment provides for a female locking means on the female connector 100, and a male locking means on the male connector 200 is equivalent and also understood by the invention.
    [0099] The locking means 250 of the male connector 200 is preferably complementary to the locking means 150 of the female connector 100.
    [00100] According to the invention, when the locking means 250 are of the female type, they are formed of a smooth surface 260 which has an invariable axial section in a substantially continuous part of the distal coupler 240, and of a retaining means 252 extended transversely.
    [00101] The male locking means 150, therefore, also consist of a smooth surface 160 and have a retention means 151 extended transversely, with shapes complementary to the shapes of the smooth surface 260 and the retaining means 252 of the female locking means 250 respectively.
    [00102] This embodiment therefore makes it easier to clean the locking means, as they reduce the protruding edges on the surfaces 160, 260 to be cleaned, in contrast to the thread locking means, the use of which is widespread in the prior art. .
    [00103] They respond especially to that definition and, therefore, are understood by the invention, the means of locking to the bayonet, by fitting (that is, by elastic deformation of a retaining element that protrudes from the surface of the distal part of one of the means locking, followed by penetration into a complementary hole provided on the surface of the distal part of the other locking means, see, for example, Figure 9), etc.
    [00104] In the case of bayonet locking means, the retaining means 151 of the male locking means comprises at least one pin extended transversely towards the outside from the smooth outer surface 260. Preferably, the retaining means 151 comprises two pins, extended on both sides of the distal coupler 140 of the male connector 100.
    [00105] Each pin 151 can have a circular, square, elliptical section, or any other section adapted to effectively keep the male connector 100 in relation to the female connector 200.
    [00106] The retaining means of the female locking means 250 consists of at least one groove 252 formed on a surface 160 of a collar 251. The groove 252 can be through, to then form a crack as shown in the attached Figures, or partially blind.
    [00107] The collar 251 is integrally formed with the casing 220. As an alternative of realization, the collar is joined to the casing, for example, by gluing or welding or by any other means that allows the said installation. The collar 251 shown here is presented in the form of a tube connected, at a proximal end, by the ribs 260 to the housing 220. In this way, the passages 261 are placed between the ribs 261. Here, the ribs 260 are four in number and uniformly spaced on a circumference of collar 251. As a consequence, the passages are also four in number and evenly spaced on said circumference of collar 251. Such a structure allows perfect cleaning of the collar and, therefore, of the male connector 200.
    [00108] Preferably, the female locking means 250 comprises at least as many grooves 252 as there are pins 151 in the male locking means 150.
    [00109] Each groove 252 preferably has a free end that ends at a distal end of collar 251, the other end being closed and provided to form a longitudinal stop for pin 151.
    [00110] In addition, the grooves 252 are arranged on the collar 251 so that their respective free end is in front of a pin 151 when the distal ends 140, 240 of the male connectors 200 and female 100 are brought into contact before the connection, as shown in Figure 5.
    [00111] Thus, during the connection of male connectors 200 and female 100, each pin 151 of the male locking means 150 penetrates respectively in a groove 252 of the female locking means 250.
    [00112] As an alternative (illustrated in Figures 3b and 4b), the central part 270 of the distal coupler, surrounded by the collar, is threaded in such a way as to constitute a pluggable female Luer-Lock inlet. For this, the distal part of the collar 251 is shortened so that the face of the central part 270 can be accessed radially. In this way, a female locking means will be obtained which can be connected both to a male locking means 150, as described with reference to Figure 2, and to a complementary male locking means of the "Luer-Lock" type.
    [00113] The value of this embodiment is to allow especially the connection of the connector 200 to a syringe that comprises a locking means of the Luer-Lock type.
    [00114] Another advantage of this embodiment is the ease of cleaning, since the inner surface 260 of the collar 251 and the outer surface 160 comprising the pins 151 are smooth, while the central threaded part 270 can be accessed directly by a manipulator that want to clean it.
    [00115] In another alternative, (not shown in the Figures), the female locking means may include a collar comprising at least one pin projected from its internal surface, complementary to a male locking means comprising a smooth external surface where a groove (not through) is formed.
    [00116] These embodiments are advantageous because they guarantee the operator that the male connectors 200 and female 100 are effectively well connected.
    [00117] In effect, the operator can visually and mechanically check whether pin 151 is exactly at the bottom of groove 252, which implies that tubes 124 and 215 are effectively well connected, unlike conventional connectors that include threaded locking means, which do not allow such checks.
    [00118] The length of a groove 252, preferably, is at least equivalent to the maximum relative distance traveled by connectors 100, 200 when they are connected by an operator. This relative distance will be further detailed below.
    [00119] The width of a groove 252 is roughly equal to the diameter of the corresponding pin 151, obtained in the direction transverse to the direction of insertion of pin 151 in groove 252. Thus, pin 151 can move longitudinally in groove 252 remaining blocked transversely during its insertion in the groove 252.
    [00120] If necessary, groove 252 will still have a curved shape to keep pin 151 fixed longitudinally when it reaches the stop. For example, groove 252 has a longitudinal part 252a, with a length at least equivalent to the relative distance traveled by connectors 100, 200 during their connection, and a transverse part 252b, extended in a direction substantially perpendicular to the direction of insertion of pins 151 .
    [00121] Alternatively, the angle formed between the transverse part 252b and the longitudinal part 252a of the groove 252 is sharp, to strengthen the maintenance of the pin 151, and therefore the locking of the connector set 100, 200.
    [00122] However, whatever the embodiment, the grooves 252 formed in a given collar 251 are identical. In particular, they exhibit the same size, shape and orientation, so that pins 151 can easily penetrate the associated groove 252.
    [00123] Alternatively, the grooves 252 and the associated pins 151 can have different widths two by two, so that a given pin 151 (with a given transverse diameter) cannot penetrate a groove 252 that is too small, to ensure an adjustment function.
    [00124] According to an embodiment, the closed end of each groove 252 is additionally provided with a recess or seat 253 disposed at the end of groove 252 which serves as a stop to pin 151. If applicable, recess 253 is moved in relation to the groove axis 252, to lock transversely to pin 151 in groove 252, and thus further improve the locking of the connector set 100, 200. For example, when groove 252 is curved, as specially illustrated in Figures 4 and 5, the recess 253 is disposed at the closed end of the transverse part 252b of the groove 252 and displaced towards the distal end in relation to the axis of said transverse part 252.
    [00125] Referring to Figures 5 to 7, the interactions of the different elements that have been described will be described.
    [00126] Figures 5 and 6 represent female connectors 100 and male 200 in a stable position downstream of the seal. In that position, the membrane 130, respectively 230, seals the passage 141, respectively 211, so that a surface downstream of the membrane 130, respectively, 230, is flush with the downstream end of said passage.
    [00127] For information, in this position, a manipulator of connector 100, 200 can easily clean said surface downstream of the membrane to reduce the risk of nosocomial infections that could result from poor cleaning or complex cleaning of that surface.
    [00128] Thanks to the locking means 150, 250 and the structure of the male connectors 200 and female 100 according to the invention, the tightness in back pressure increases markedly, without impairing its performance in terms of repeated connections / disconnections. Furthermore, the use of rigid cups 134, 234 prevents any expulsion of the septa 130, 230, except the connectors 100, 200 according to the invention under the effect of strong pressures.
    [00129] During a first use, the operator cleans the distal end of the membranes 130, 230 to completely eliminate the presence of germs or bacteria, as well as the means of locking the bayonet 150, 250 (and, if applicable, the central part 270).
    [00130] It should also be noted that the replacement of conventional threads with bayonet locking means 150, 250 (and, if applicable, the central part 270) according to the invention greatly facilitates cleaning.
    [00131] After cleaning, the operator puts the respective septa of the male connector 200 and the female connector 100 in contact, as shown in Figure 5, then connects the set. This connection between connector 100 and connector 200 is made by locking pins 151 of distal coupler 140 of female connector 100 in the corresponding grooves 252 of distal coupler 240 of male connector 200.
    [00132] It is notable that, as the distal couplers 140 and 240 of the two female connectors 100 and male 200 are structurally similar (except, of course, their respective locking means), their respective membranes 130, 230 are flush with the end level distal from its distal coupler 140, 240. Thus, the coupling / uncoupling of male connector 200 and female connector 100 is performed in a single axial movement. In reality, it is more necessary to fix distal couplers 140, 240 of female connectors 100 and male 200 before starting to push the connectors against each other, these two operations being carried out simultaneously thanks, on the one hand, to the structure of the distal couplers 140, 240, and on the other hand, to the locking means according to the invention.
    [00133] More precisely, the operator positions the pins 151 of the female connector 100 in relation to the corresponding grooves 252, then slides the connectors 100, 200 relative to each other by pushing the female connector 100, resting on the handling means 143 of the distal coupler 140, towards male connector 200.
    [00134] During this manipulation, the distal end of the male connector 200 pushes the distal end of the membrane 130 of the female connector 100, which, on the one hand, forces the membrane body 131 to compress, and on the other hand, forces the distal end 125 of the hollow tube 124 to traverse, through the slit 133, the membrane thickness located at the distal end of the membrane 130.
    [00135] Once the distal end 125 of the tube 124 has passed through the thickness of the membrane of the distal end of the membrane 130, the distal end 125 of the tube 124 establishes a supporting contact with the septum 230 of the connector 200. The distal end 125 the tube 124 then pushes the septum 230, on one side, towards the underlying spring 231 and, on the other side, towards the pipe 214, which then crosses the septum 230 through the gap 233 that exists there.
    [00136] The impulse continues until the distal end 125 of tube 124 of female connector 100 receives the distal end of tube 214 of male connector 200. As a result of the connection, a passage of liquid is carried out between male connectors 200 and female 100.
    [00137] The relative distance traveled by connectors 100, 200 during manipulation is defined by the length of the longitudinal part 252a of the grooves 252. In this final position, in which connectors 100, 200 are connected and are in fluid communication, pins 151 they are on the stop at the bottom of the longitudinal part 252a of the grooves 252.
    [00138] The operator then rotates the connectors 100, 200 in relation to each other to position the pins 151 on the closed end of the transverse part 252b of the grooves 252, until reaching its seat 253, and lock the connector set 100, 200.
    [00139] At disconnection, the operator rotates the connectors 100, 200 in relation to each other in the opposite direction of the locking, to remove the pins 151 of the transversal part 252b from the grooves 252, then separate the connectors 100, 200 with the help of the impulse of the two springs. The pins 151 therefore leave the longitudinal part 252a of the grooves 252, the membranes 130, 230 progressively cover the tube 124, 214 again, respectively, and the membranes 130, 230 tightly seal the respective distal ends of the connectors 100, 200.
    [00140] During a connection or disconnection, tightness is ensured throughout the operation. In effect, the tightness is first assured by the contact of the distal end of the membrane 130 at the septum 230, then by the contact of the distal end 125 of the hollow tube 124 at the septum 230 of the male connector 200 - said contact being maintained by locking the connector set - and finally by inserting tube 214 into hollow tube 125.
    [00141] It is necessary to clarify that the invention admits the accomplishment of numerous modifications without its scope being distorted.
