Tubing systems are described herein. A tubing system can include a tubing assembly, a tubing system component, and a coupling portion. The tubing assembly includes a tubing and a tubing assembly connector coupled to the tubing. The tubing assembly connector defines a connector lumen in fluid communication with the tubing lumen. The tubing assembly connector has a tubing assembly connector elastic modulus greater than the tubing elastic modulus. The tubing system component has a component connector abutted against the tubing assembly connector. The component connector has a component connector elastic modulus greater than the tubing elastic modulus. The coupling portion is overmolded over the tubing assembly connector and the component connector to couple the tubing to the tubing system component.

Medical devices are provided comprising a spike including proximal and distal ends, and a central axis extending from the proximal to the distal end; a valve body; a biasing body which biases the valve body; a distal tube that moves integrally with the valve body to both sides in the axial direction relative to the spike; a proximal tube fixed in the axial direction relative to the spike, the distal tube comprising a guided portion guided toward the proximal tube, and an engagement control unit which moves the guided portion toward one side in the radial direction by connection of the different medical device to the distal tube allowing the guided portion to engage with the proximal tube, and moves the guided portion toward the other side in the radial direction releasing engagement with the proximal tube when the different medical device is detached from the distal tube.

A pair of coupling members for a joint closed fluid transfer system. Each coupling member of the pair of coupling members includes a coupling housing having a longitudinal axis, a fluid connection, and a coupling side. A sealing member receptacle, which is arranged in the coupling housing, includes at least one fluid-tight chamber formed by at least one sealing member arranged in the sealing member receptacle. A spike in the coupling housing in a spike receptacle, in particular a spike arranged eccentrically in the coupling housing, fluidly communicates with the fluid connection. In a first embodiment, the coupling members are each complementary to one another, in particular identical in construction, and are connectable without an adapter by a relative angular offset about their longitudinal axis, preferably by a relative angular offset of 90°.

A catheter enclosure device for locking an intravenous catheter therein with tamper-evident features to deter unauthorized use. The catheter enclosure device may be particularly useful for peripherally inserted central catheters (PICC). The enclosure device comprises an open-top box and a removable lid for covering the box. The open-top box has a compartment for holding the proximal end of an intravenous catheter. The lid comprises a panel for covering the open portion of the open-top box and a folding wing that overhangs the forward end of the box when covering the box. The folding wing further comprises a retaining anchor. When the folding wing is folded down, the retaining anchor inserts into a locking slot on the forward end of the box, thereby preventing the lid from being removed off the box. Also disclosed are methods for using the catheter enclosure device.

A simply lockable quick coupling for releasably connecting a hose to an implantable apparatus, comprises a first attachment piece that can be connected to the hose and a second attachment piece that can be connected to the apparatus, wherein the attachment pieces can be rotated relative to each other in the locked state.

A strain relief adapter (100) for a medicament delivery device (200) includes a flexible body (101) having a first end (102) configured to connect to one of a fluid connector and a pump connector, a second end (104) configured to connect to tubing, a hollow fluid path (108, 110, 112, 114) therethrough fluidly connecting the first and second ends, and a plurality of external strain relief ridges (106) disposed between the first and second ends.

A fluid handling cassette, such as that useable with an automated peritoneal dialysis (APD) cycler device or other infusion apparatus, may include a generally planar body having at least one pump chamber formed as a depression in a first side of the body and a plurality of flowpaths for a fluid that includes a channel. A patient line port may be arranged for connection to a patient line and be in fluid communication with the at least one pump chamber via at least a first one of said flowpaths, and an optional membrane may be attached to the first side of the body over the at least one pump chamber. In one embodiment, the membrane may have a pump chamber portion with an unstressed shape that generally conforms to the depression of the at least one pump chamber in the body and is arranged to be movable for movement of the fluid in a useable space of the at least one pump chamber. One or more spacers may be provided in the at least one pump chamber to prevent the membrane from contacting an inner wall of the at least one pump chamber. The patient line, a drain line, and/or a heater bag line may be positioned to be separately occludable in relation to one or more solution lines that are connectable to the cassette.

A slip luer assembly includes a hub member and a latch member coupled to the hub member. The hub member includes an outer hub surface, an inner hub surface and a window surface. The window surface defines a window extending from the outer hub surface to the inner hub surface. The latch member includes at least one blade. The latch member is configured to be actuated between a first position and a second position. In the first position, the at least one blade is not positioned within the window of the hub member. In the second position, the at least one blade is positioned at least partially within the window of the hub member.

A sealing assembly for a fluid infusion device includes a base plate, a reservoir port receptacle, a flow base component, and a needle sealing element. The receptacle receives the reservoir port, and has proximal and distal ends, and a needle entry in the distal end to receive a hollow needle of a fluid reservoir. The flow base component has an inlet structure defining a fluid chamber, and a needle guide pin protruding therefrom. The end of the guide pin fits within the hollow needle. The needle sealing element has a proximal flange adjacent to the inlet structure, a distal flange opposite the proximal flange, a neck section between the flanges, and a needle opening extending through the neck section. The needle sealing element is positioned within the port receptacle such that the neck section surrounds the end section of the needle guide pin.
