One embodiment is directed to a system for injecting, comprising a syringe body defining an interior medicine chamber; a stopper member configured to be inserted into the interior medicine chamber to contain medicine within the medicine chamber; a plunger member configured to be manually manipulated to insert the stopper member relative to the syringe body; and a needle having proximal and distal ends, the proximal end comprising an anchoring geometry configured to be at least partially inserted into the stopper member such that upon retraction of the stopper member, the needle is pulled proximally along with the stopper to be at least partially contained within the interior medicine chamber.

A valve (20) for the sealing cuff (10) of a tracheal tube has a valve member (40) urged against a valve seal (36, 37) by an MRI-safe resilient member (42) of neoprene or nitrile. The valve includes a two-part actuator (70) by which the valve member is displaced. Before use, during storage, the valve member is in a closed position with the resilient member relatively relaxed. When the valve is opened for the first time by inserting a syringe or the like, the two-part actuator arrangement is moved forwards to unseat the valve member to allow flow. This causes inclined surfaces (88) and (92) on the two parts (72) and (73) of the actuator to rotate the forward part slightly. When the syringe is removed to allow the valve to close, the forward part of the actuator latches on a surface (34) of the housing (21) in an operational position where the valve is closed.

An aseptic coupling system includes a first and second connectors having inboard mating portions, outboard terminal connections, first and second valve seals, and first and second valve elements. When the first and second connectors are joined in a coupled condition, the first and second valve elements are each moved from a shutoff position in sealing engagement with the first and second valve seals to a flow position separated from the first and second valve seals to permit flow therebetween, thereby defining a flow path between the outboard terminal connections. In the coupled condition, non-wetted surfaces of the first valve seal are sealed off from the flow path by sealing engagement with a flow passage defining annular wall of the second connector, and non-wetted surfaces of the second valve seal are sealed off from the flow path by scaling engagement with a flow passage defining annular wall of the first connector.

An outlet (4) for a pouch (1) in a urostomy appliance is provided. The outlet has a valve with a valve housing (5) and a valve stem (6) that is movable in the longitudinal direction with respect to the valve housing. In a position of the valve stem, the stem can freely rotate with respect to the valve housing, so as to prevent kink and obstructions in a tube connecting the valve with a collecting bag. A urostomy appliance with an outlet is also provided.

The invention relates to a releasable blocking system (1) of a catheter (4), comprising a base (2) adapted to receive a catheter (4), and a shell (3), mounted in rotation on the base (2) between an open position, in which the shell (3) is away from the base (2), and a closed position, in which the shell (3)is hooked on the base (2) and blocks the catheter (4) in position, in which: the system comprises an actuator (25) provided with a guide aperture (251), mobile in a housing (20) between a rest position and a blocking position, the actuator (25) comprising a first drive element (255), the shell (3)comprises a second drive element (33), adapted to cooperate with the first drive element (255) when the shell (3) is shifted from its open position to its closed position, and shift the actuator (25) to its blocking position.

The invention relates to a check valve assembly (100) having an inlet (205) and an outlet for medical fluids, comprising a valve body (101), wherein the check valve assembly (100) in an initial state allows a flow of a working fluid and/or a sterilization fluid through the check valve assembly (100) in both directions of flow, that is from the inlet (205) to the outlet and vice versa, and wherein the check valve assembly (100) in an operating state allows only one direction of flow of the working fluid, wherein the check valve assembly (100) comprises a pin-pin-reception connection, which is embodied so that the check valve assembly (100) can be transferred from the initial state into the operating state by applying force on the pin-pin-reception connection and/or by an impression of path on the pin-pin-reception connection.

A medical device system including a first container and a second container, the first container including a first container outer body defining a first interior space connected to a first opening of the first container; and a first container-side valve configured to be activated, upon connection of the second container to the first container, from a normally closed position into the first interior space to an activated position, and the second container including a second container outer body defining a second container interior space and a stem fluidly connected to the second container interior space, wherein, upon connection of the second container to the first container, the first container-side valve is configured to be brought into contact with the stem and the stem is configured to activate the first container-side valve from the normally closed position to the activated position.

A mechanical fluid pressure modification valve, or MFLP-valve, is set forth. The MFLP-valve can be actuated upon movement of a movable pressure system member of a medical pressure system reaching a selected position. Additionally, the MFLP-valve can be actuated based on a pressure condition of the system. When the MFLP-valve unseals, a pressure differential between a pressure chamber and a volume outside of the chamber can be relieved. Disengagement of the movable pressure system member from the MFLP-valve can enable the MFLP-valve to re-seal. The MFLP-valve may include a flag that indicates the position of the movable pressure system member. The MFLP-valve may be provided in a diaphragm-type pressure source.

A medication container adapter that utilizes a push-pull valve for adapting medication containers for use with enteral syringes that are filled on semi-automatic and automatic filling machinery. The enteral syringes are filled when the medication container is in the inverted filling position. The push-pull valve comprises of a stationary portion and a poppet slidably inserted into the stationary portion. The poppet is an annular member having a central channel and a fluted axial outlet from the central channel. The push-pull valve can be configured to be pressed onto an existing medication container adapter or manufactured as an integrated part of the medication container adapter so that it can either be screwed onto or pressed into the medication container neck.

A connector for connecting a container containing a medical fluid to a vascular access device may include an upper housing defining a first internal chamber, and a lower housing coupled to the upper housing and defining a second internal chamber for circulation of the medical fluid into the outlet. The connector may further include a slider disposed at least partially in the first and second internal chambers, and a plug coupled to a distal end of the slider. The slider may be reciprocally movable between (i) an open position, where the plug is spaced apart from a floor of the internal chamber to allow the medical fluid to flow through the outlet, and (ii) a closed position where the plug abuts the floor of the second internal chamber to block the medical fluid from flowing through the outlet.
