The wound therapy apparatus may include a wound interface sealingly securable to the skin surface around a wound bed to encloses the wound bed within an enclosed space that is fluid-tight. The wound interface may be sufficiently deformation resistant to distend at least a portion of the wound bed into the enclosed space when pressure p.sub.0 within the enclosed space is less than ambient pressure p.sub.amb. Fluid may be communicated with the enclosed space when the wound interface is sealingly secured to the skin surface in order to vary a pressure p.sub.0 within the enclosed space periodically over the pressure range p.sub.min≤p.sub.0≤p.sub.max. The variation of the pressure p.sub.0 may distend the wound bed into communication with a pad received within the enclosed space and decreases the wound bed contact with the pad. Related methods of use of the wound therapy apparatus are also disclosed.

A fill adapter system for an infusion pump assembly. The system includes a reusable fill adapter base, the base including a volume control mechanism to adjust an available fill volume of a reservoir of the infusion pump assembly and a pump mechanism configured to pump air into a fluid vial. The system also includes a vial adapter assembly including a first needle configured to penetrate a septum of the fluid vial for fluidly coupling the pump mechanism to the fluid vial and a second needle having a first end configured to penetrate the septum of the fluid vial and a second end configured to penetrate a septum of the reservoir of the infusion pump assembly to allow transfer of fluid from the fluid vial to the reservoir of the infusion pump assembly in response to air being pumped into the fluid vial and a needle carriage adapted to carry the first needle and the second needle, wherein the needle carriage slidably attached to the interior of the vial adapter assembly, wherein the needle carriage adapted to slide from a vial end of the vial adapter to a receptacle end of the vial adapter.

Intravenous cannula devices configured to prevent blood backflow and needle prick injuries include a catheter assembly and a needle guard assembly. The catheter assembly includes a hub having a coaxial recess and a valve member positioned therein. The valve member is cylindrical and includes a distal surface having slits collectively defining prongs configured to open and close upon passage of a needle therethrough. Cannula devices configured to prevent needle stick injuries include a safety release component at a distal end of the needle guard assembly. The safety release component includes moveable locking elements configured to fit within an annular groove defined by a proximal portion of the hub upon movement of a needle through the safety release component. Proximal retraction of the needle through the safety release component causes the moveable locking elements to be displaced from the annular groove, thereby decoupling the catheter assembly from the needle guard assembly.

System for gas treatment of cellular implants. The system enhances the viability and function of cellular implants, particularly those with high cellular density, for use in human or veterinary medicine. The system utilizes a miniaturized electrochemical gas generator subsystem that continuously supplies oxygen and/or hydrogen to cells within an implantable and immunoisolated cell containment subsystem to facilitate cell viability and function at high cellular density while minimizing overall implant size. The cell containment subsystem is equipped with features to allow gas delivery through porous tubing or gas-only permeable internal gas compartments within the implantable cell containment subsystem. Furthermore, the gas generator subsystem includes components that allow access to water for electrolysis while implanted, thereby promoting long-term implantability of the gas generator subsystem. An application of the system is a pancreatic islet (or pancreatic islet analogue) implant for treatment of Type 1 diabetes (T1D) that would be considered a bio-artificial pancreas.

A fill adapter for filling a reservoir and a related method are disclosed herein. The fill adapter includes a button assembly actuator and a pump chamber plunger actuator hingeably attached to the button assembly actuator, wherein the actuation of the button assembly actuator actuates the pump chamber plunger actuator and wherein the pump chamber plunger actuator actuates a pump chamber membrane before the at least one button assembly is actuated.

The present disclosure generally relates to a negative wound therapy (NPWT) system (100) comprising a mobile negative pressure device (101), a tubing assembly (105) and a non-absorbent or an absorbent dressing (104).

Provided is an applicator for the dispensing of a powder such as a pharmaceutical powder, on a target location. Also, provided are methods of applying a powder on a surface using the applicator.

An intravenous delivery system may operate by gravity feed, and may have a liquid source containing a liquid, a drip unit that receives the liquid from the liquid source, and tubing that receives the liquid from the drip unit for delivery to a patient. A flow rate sensor may be used to measure a flow rate of liquid through the intravenous delivery system, and may generate a flow rate signal indicative of the flow rate. A controller may receive the signal, and may compare the flow rate with a desired flow rate. If the flow rate is more or less than the desired flow rate, the controller may transmit a control signal to a flow rate regulator. The flow rate regulator may receive the control signal and, in response, modify the flow rate to bring the flow rate closer to the desired flow rate.

A dressing includes a drape, a metal coating provided on a skin-facing surface of the drape, a pressure-sensitive adhesive provided on a lower surface of the metal coating, and a gasket having a frame shape. The drape is a thin film. The gasket includes an inner edge defining an opening and an outer edge offset inwardly from an outer periphery of the drape. The gasket is in contact with the metal coating and leaves a margin of pressure-sensitive adhesive around the gasket.
