A coupling apparatus includes a first component having a first non-mechanical valve, a second component having a second non-mechanical valve, and a third component having a first end for coupling with the first valve and a second end for coupling with the second valve. The third component has an elongated bore such that when the first end is coupled to the first valve and the second end is coupled to the second valve, a passageway is defined therethrough. The coupling apparatus includes a breakaway portion disposed between the third component and the second component and the first and second valves automatically close when the second and third components are separated from one another.

A coupling for fluid-tight connection of two fluid-guiding portions in medical applications. The coupling is an axially lockable quick-connect coupling and comprises a male coupling portion having a continuous first passage and a female coupling portion adapted to be slipped over the male coupling portion and having a continuous second passage. A preferably circumferential radial sealing is provided on the outer periphery of the male coupling portion and/or on the inner periphery of the female coupling portion.

An adapter for use with a drug delivery device having a reservoir for containing a product, the reservoir having a distally projecting end-piece defining a passageway for the transfer of the product from the reservoir, includes a collar engageable with the end-piece, an adaptor securing member limiting translational movement of the collar with respect to the end-piece once the collar is engaged with the end-piece, at least one adaptor anti-rotation member limiting the rotation of the collar with respect to the end-piece once the collar is engaged with the end-piece, at least one deactivating member neutralizing the adaptor anti-rotation member in response to a turning torque equal or greater than a predetermined value applied to the collar when the collar is engaged with the end-piece, thereby allowing the rotation of the collar with respect to the end-piece.

Luer lock connectors are provided that include an inner core of a hard material, the inner core sized and shaped to mate with an inner portion of an opposing luer lock connector, an outer layer of a soft material disposed on an outer surface of the inner core, and a plurality of grip features disposed on an outer surface of the outer layer, wherein the plurality of grip features are configured to provide a slip resistant grip surface. Infusion sets and infusion set luer lock connectors are also provided.

Disclosed herein are several embodiments of a reduced pressure appliance and methods of using the same in the treatment of wounds. Some embodiments are directed to improved fluidic connectors or suction adapters for connecting to a wound site, for example using softer, kink-free conformable suction adapters. Certain embodiments are directed to connectors used to connect fluid passage tube used in transmitting negative pressure to a fabric channel used in a suction adapter.

A catheter connector device for connecting a syringe or other fluid application and/or removal device, and a catheter is provided comprising a port for receiving a catheter, a port for connecting a syringe or other fluid application and/or removal device, and a push-button for securing the received catheter. The push-button includes internal arms embracing internal cantilevered structures in turn embracing a flexible tubular sleeve into which the catheter is inserted; when the push-button is pushed to an inward position, the arms of the push-button apply a pressure on the cantilevered structures, and thus on the tubular sleeve, gripping the catheter.

A connector assembly for a fluid delivery system includes a conical body defining an interior cavity and a discharge outlet, the discharge outlet defining an internal passage in fluid communication with the interior cavity; and a connector removably attached to the discharge outlet. The connector includes a central body configured to be at least partially positioned within the internal passage of the discharge outlet, and an annular connector portion connected to the central body and configured to releasably engage an exterior of the discharge outlet, the central body defining an internal channel within the central body that is in fluid communication with the interior cavity of the conical body when the connector is attached to the discharge outlet.

A connecting system for connecting a medical tubular line to a medical fluid transfer system, the tubular line including a plug-in component with a first fluid channel and the fluid transfer system including a coupling component with a second fluid channel. The plug-in component can engage in the coupling component to establish a passageway for a medical fluid, which passageway connects the fluid channels to one another. By disposing a first passive transponder in the plug-in component and a second passive transponder in the coupling component at a distance below a predefined threshold value relative to one another, communication of a read/write unit with both transponders via a single antenna is made possible when the plug-in component is engaged in the coupling component so that identification data for the identification of the tubular line and the fluid transfer system stored in the transponders can be read by a read/write unit via a single antenna.

In an embodiment, a connector or connector assembly for attaching a nasal cannula with a gas delivery hose includes a sensor port for a sensor probe positioned near an end of a nasal cannula, which can allow the sensor probe to be placed closer to the patient's nostrils than previous connector parts allowed. The connector can be configured to advantageously allow the nasal cannula to rotate relative to the gas delivery hose, thereby allowing a patient or healthcare provider to untangle or otherwise straighten the hose or the cannula. The connector assembly can be configured to automatically align locking protrusions on a first component with locking recesses on a second component, where insertion of the second component within the first component causes the second component to rotate relative to the first component, thereby aligning the locking protrusions with associated locking recesses.

A manual infusion set comprises a top connector lockable in a plurality of positions. The top connector and tubing is initially loaded from the top and then slid forward in order to puncture the septum. Once the connector is attached, it cannot be rotated. With the connector locked in place, flexible tubing connects the septum hub with a medicine pump, which continually supplies medicine such as insulin to a user.
