Definitions
- the invention relates to a connector for establishing a fluid communication under the control of a valve, particularly for use in the medical field.
- a connector comprising a rigid casing and an elastically deformable valve, the casing determining an elongated chamber along an axis, this chamber having a distal end and a proximal end, and being accessible on the one hand by a fixed endpiece projecting axially.
- valve in the distal end of the chamber and secondly by an axial duct formed at the proximal end of the chamber and in which can be introduced a movable nozzle
- the valve being a tubular one-piece body of elastomeric material with a leaktight wall housed in the chamber, this valve having a distal end constituting a tubular space into which said fixed tip and having an opposite end shaped in particular to form a plug in said axial duct, this plug being split to communicate with said tubular space, the valve and the housing being shaped and dimensioned so that the cap is elastic.
- nt movable between a closed position where it is in sealing contact with the duct wall and is laterally constrained by this wall to close the slot and an open position where the plug is no longer constrained laterally by the wall of the duct. so that her slit can open.
- the connectors of this type it concerns those whose valve is elastically deformable in said chamber when it is pushed by the movable tip introduced into said conduit by creating a spring effect that allows it to resume its original shape when the tip mobile is removed from said conduit.
- the invention aims to provide a connector whose valve is integrally sealed laterally, is elastically deformable spring effect, surrounds the fixed end like a thermowell, and meets several requirements:
- valve must not create a dead volume inside the connector, which is synonymous with aspiration to disconnect;
- valve spring deformation capacity essentially concerns the stopper and a portion of the intermediate valve between the stopper and said tubular space, the valve and the fixed nozzle being shaped so that the valve is permanently tightened on the valve; fixed tip without forming a significant dead volume in said space regardless of the deformation of the valve,
- the fixed tip and the valve are shaped so that the valve is held on the fixed tip without bending under the thrust of the movable tip
- the slot of the valve is constituted by a proximal slot molded so that the slot is open when the cap is out of said conduit and is closed when the cap is constrained laterally by the wall of the conduit, this proximal slot being followed by a pierced distal slot adapted to make the molded slot communicate with said space when the slot is open, the pierced slot being closed when the cap is constrained in the conduit, the pierced slot and a portion of the molded slot being traversed by the end piece; fixed when the plug is out of said conduit without the movable tip enters the slot.
- the connector still has one or more of the following features:
- the fixed tip has an outer shoulder on which the valve is in abutment
- Said shoulder is frustoconical in shape
- Said intermediate portion of the valve has a flange which cooperates with the wall of the chamber to prevent an outlet of the valve from the connector at the rise of the valve under the effect of a back pressure;
- valve has at said pierced slot protruding heels which enter said conduit when the valve back into the conduit under the effect of a back pressure and act to compress the slot there.
- FIG. 1 is a diagrammatic axial section of the connector at rest
- FIG. 2 is a schematic axial section of the connector in the connection state
- Figure 3 is a perspective view of the valve before mounting in the housing of the connector
- Figure 4 is an axial section of the valve before mounting in the housing of the connector
- Figure 5 is a schematic perspective cut axially of the valve in place and at rest in the housing; • Figure 6 is a schematic perspective cut axially of the valve in place in the housing after introduction of the movable tip.
- the connector shown in the figures comprises: • a housing (1) consisting of a female housing part (IA) and a male housing part (IB) fixed (screwed or clipped or glued or welded) into the female part , these two parts cooperating to constitute a chamber (2) elongate along an axis, accessible at a distal end by a fixed axial end piece (3) integral with the female housing part and accessible at its proximal opposite end by an axial duct (4). ) formed in the male crankcase portion; An elastically deformable one-piece valve (5) for example made of silicone and with a laterally sealed wall disposed in said chamber, this valve constituting at a distal end (5b) a space (6) in thimble that receives the fixed end (3). ) and at its opposite proximal end a plug (5a) located with lateral sealing in the axial duct (4) and which is flush with the opening end (8) of this duct.
- a housing (1) consisting of a female housing part (IA)
- the valve has a slot (9) of which a part is molded (9A) and is closed in the axial duct when the valve is at rest in the housing and a following part (9B) is slotted, for example with a scalpel, for make the molded part communicate with the space
- the valve (5) has between the tubular space (6) and the plug (7) an intermediate valve portion (10).
- the valve is shaped to tightly tighten the fixed tip (3) irrespective of the state of the valve and this nozzle has near the proximal end of the space (6) a frustoconical shoulder (11) on which s 'presses the valve and prevent it from sliding on the fixed tip under the thrust of the movable tip.
- the valve At its distal end, the valve has a side flange (12) applied against the base face (13) of the chamber and held by the male housing portion screwed into the female housing portion.
- the intermediate portion (5c) of the valve is thicker than the portion (5b) of the valve which determines the gap (6) and has a shoulder (14) and, above this shoulder, two beads (17). on each side of the cut slit.
- the plug (5a) has an approximately ellipsoidal cross-section and the molded slot (9A) has an approximately ellipsoidal shape, the major axes of the two ellipses being perpendicular.
- the ellipsoidal section of the plug is constrained by its contact with the conduit wall to take a circular shape and the molded slot (9A) is forced to close.
- the movable tip (15) When the movable tip (15) is introduced and pushed into the conduit, it pushes the plug into the chamber, out of the conduit, so that the molded slot which is no longer compressed opens itself and that the cut slot is penetrated by the fixed tip, while the intermediate portion (5c) of the valve expands laterally into the chamber by coming into contact with the upper wall (16) of the chamber.
- the sheath By bearing against the wall of the housing, the sheath stores elastic energy to ensure the spring function, and can not close on itself thanks to the presence of the fixed tip.
- the casing has at the transition between said duct and said chamber a frustoconical cross section intended to ensure progressive deformation of the plug during the introduction of the mobile nozzle into the duct or removal of this nozzle.
- the two protruding heels enter the proximal duct of the casing and are compressed towards each other, which compresses the slot at this point and allows good resistance of the connector against pressure.
- the collar on the valve is "shoulder". Under the effect of a back pressure, the valve is pushed upwards (piston), the shoulder prevents it from being extruded in the previous conduit and partly leaves the connector which would make any reconnection difficult.
- the valve can only deform in its intermediate part and the space in the housing allows it. Under the thrust of the male mobile end, it blossoms while being crushed on the shoulder of the fixed tubular endpiece. The seal is obtained by the imprint of the male end in the valve.
- the stroke of the male end is variable according to its geometry (tolerances mini / maxi), if the male luer is mini, it sinks a lot and comes flush with the tubular end of the lock, otherwise there is a space between the male end and the fixed end, preferably a space at most equal to 1, 7 mm.
