Wound irrigation system
11504457 · 2022-11-22 · ·

A wound irrigation system and method of making and using. The system uses a pored, closed-ended delivery conduit to enhance the consistency and speed with which anti-microbial or related irrigation fluids may be delivered in order to promote cleansing, debridement and biofilm reduction in wounds. The ease of use of the system as a moist wound healing cascade makes it applicable to both in-home and in-facility environments that is not offered through traditional instillation negative pressure systems. In one form, the fluid delivery conduit is used as part of a dual-conduit approach in order to also help promote the removal of drainage, waste, irrigation overflow or other fluid from the wound. Utilization of such a pored, closed-ended delivery conduit in conjunction with a separate drainage conduit infusing helps reduce the frequency of dressing changes as well as the likelihood of microorganism formation and colonization.

Infusion tube assembly, infusion device, and infusion method

An infusion device includes an infusion pump and an infusion tube assembly. The infusion tube assembly includes a first tube body connected to the infusion pump, a tube joint structure having first, second and third tube joints, a second tube body, and a clamping device on the second tube body. The clamping device is to clamp the second tube body. An infusion method includes instructing the infusion pump to perform an infusion operation. When bubbles are detected in a liquid in the infusion tube assembly, the infusion pump is instructed to stop the infusion operation and a bubble alarm is generated. After the infusion pump stops the infusion operation, it is determined whether a pressure of the liquid first drops to a first pressure value and then rises to a second pressure value. If yes, a rinsing operation is performed.

Portable enteral feeding apparatus

An enteral feeding apparatus includes a pod having an expansile pouch which defines a reservoir for enteral fluid and a gas impermeable barrier surrounding the pouch. The pod has an inlet port for delivery of enteral fluid into the pouch and an outlet port having a seal which is pierceable to release enteral fluid from the pouch for delivery to a PEG via a feeding line. The expansile pouch provides the sole force by which enteral fluid is delivered from the pouch through a regulator. The system can accommodate a range of enteral fluids with a wide range of viscosities.

Closed system elastomeric pumping mechanism
11491275 · 2022-11-08 ·

A medicinal infusion system includes a safety valve for isolating residual medication by providing a single point of fluidic disconnect to encapsulate a residual fluid volume prone to spillage. The safety valve couples a medicinal repository such as an infusion pump to a medicinal supply, typically from a syringe or tubing. The safety valve includes a resilient, deformable, or hinged surface for isolating and sealing the medicinal flow to eliminate and/or isolate any residual volume in tubing and connectors. The isolating surface accommodates an inserted fitting or coupling for allowing the medicinal flow to fill the infusion pump. Upon disconnection, fluids on either side of the safety valve are therefore isolated on the respective fill or source sides, and residual volume prone to spillage is eliminated.

Wound therapy device pressure monitoring and control system

A new system for negative pressure wound therapy is described. The system includes a patient tube set connecting the wound dressing to the suction container. The patient tube set provides separate channels for applying suction to the wound site and sensing the therapeutic pressure at the wound site. A restrictor valve may also be included in order to introduce a small air leak into the system to prevent occlusions in the patient tube set.
