Analytical method for controlled and measured internal fluid after surgery

A system and apparatus for the collection of serous or serosanguinous fluid from a percutaneous site after surgery. A pump unit with one or more pumps or powered sources provide continuous negative pressure suction to draw fluid from the percutaneous site and pumps the fluid into disposable reservoirs with one-way valves that are easy to handle while maintaining sterility and a seal to prevent the loss of vacuum. Air is continuously removed from the reservoirs. Measurement and analysis of the output is performed automatically. Additionally, through such a peristaltic pump device, controlled collection of measured surgical and/or bodily fluid from a subject patient may be undertaken allowing for more effective and closer analysis, as well.

SELF-TESTING FOR NEGATIVE PRESSURE WOUND THERAPY DEVICES

A negative pressure wound therapy device can include a negative pressure source configured to be connected, via a fluid flow path, to a wound, a valve positioned in the fluid flow path and configured to, in an open state, permit supply of negative pressure from the negative pressure source upstream of the valve and, in a closed state, block supply of negative pressure from the negative pressure source upstream of the valve, a flow restrictor positioned in the fluid flow path, and a pressure sensor configured to measure a pressure differential across the flow restrictor. The device can include control circuitry configured to, in a normal operational mode, cause the valve to be in the open state and, in a test mode, perform at least one of a leak test, a flow test, or an excessive pressure test.

PORTABLE DEVICE WITH DISPOSABLE RESERVOIR FOR COLLECTION OF INTERNAL FLUID AFTER SURGERY

A system and apparatus for the collection of serous or serosanguinous fluid from a percutaneous site after surgery.

ADAPTABLE WOUND DRAINAGE SYSTEM

Provided are drainage systems that may include a drainage manifold and may be suitable for draining fluid from a tissue site. The drainage manifold may include a plurality of elongate members having a moveable end that may be adapted to configure the drainage manifold to treat a uniquely shaped tissue site. The drainage manifold may be coupled to a drainage tube with a transitional connector to provide a drainage system capable of distributing reduced pressure to the tissue site to enhance the drainage of fluids.

ANALYTICAL METHOD FOR CONTROLLED AND MEASURED COLLECTED INTERNAL FLUID AFTER SURGERY
20230226269 · 2023-07-20 ·

A method of analyzing fluid collected from a wound site, the method comprising the steps of: (a) providing a pump unit comprising: one or more pumps, one or more fluid collectors, and one or more drainage structures each in communication with an exit site of the wound site to draw the fluid through the one or more drainage structures into the pump unit and create a negative pressure at the exit site to remove and transport the fluid from the exit site and into the one or more fluid collectors, wherein the pump unit is configured to create a negative pressure, wherein the fluid removal from the exit site is provided at a controlled and measured rate; b) collecting the fluid within the one or more fluid collectors; c) removing the one or more fluid collectors; e) capping the one or more fluid collectors with a cap; and d) analyzing the collected fluid of step “b” once the fluid connectors are removed in step “c”.

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.

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.

Extensible Conduit For The Communication Of Negative Pressure And Fluids
20220347373 · 2022-11-03 ·

A conduit includes a first end configured to be fluidly coupled to a wound site, and a second end configured to be fluidly coupled to a canister. The conduit additionally includes a central lumen extending between the first end and the second end. The conduit further includes a male interlocking member on a first side of the conduit and a female interlocking member on a second side of the conduit. Both the first side and the second side extend along a length of the conduit between the first end and the second end. The female interlocking member is configured to receive the male interlocking member.
