OXYGEN CONCENTRATING DEVICE, WOUND CARE APPARATUS, AND TREATMENT METHODS

Abstract

A wound care device for delivering topical oxygen therapy, negative pressure wound therapy, and a low intensity vacuum therapy for treatment of a wound. The wound care device may include an oxygen supply MEA, an oxygen consuming MEA, a vacuum pump and motor, a pressure sensor, and a power supply and electronic controls. A dressing may be connected to the wound care device for administering topical continuous oxygen therapy and simultaneous negative pressure wound therapy to a wound. A canister or exudate trap may be positioned between the dressing and the vacuum supply port of the vacuum pump to collect and store exudates from the wound. The canister may be combined with the dressing.

Description

Claims

1. A wound care device comprising: an oxygen port for supplying oxygen gas for wound care;a vacuum port for providing a vacuum for wound care;an oxygen concentrating device fluidly connected to the oxygen port, the oxygen concentrating device including: a first membrane electrode assembly (MEA) for the production of oxygen gas from air, which comprises: a first electrode fluidly connected to a source of ambient air;a cover disposed between the first electrode and the source of ambient air, the cover including at least one passage which fluidly connects the first electrode to the source of ambient air,a second electrode spaced from the first electrode, the second electrode being fluidly connected to a first basin such that the first basin is fluidly connected to the oxygen port, anda first ion conducting membrane positioned between the first and second electrodes, which comprises:a first conductive wire connected to the first electrode, anda second conductive wire connected to the second electrode, such that the application of a substantially constant flow of electrical current through the first conductive wire and the second conductive wire electrochemically produces oxygen on the second electrode from ambient air adjacent the first electrode; anda mechanical pump comprising: a pump intake fluidly connected to the vacuum port; anda motor for driving the mechanical pump.
