A treatment system for debriding a treatment area of a tissue site and applying negative pressure is disclosed. In some embodiments, the treatment system may include an ultrasonic bubble generator fluidly coupled to a negative-pressure source, fluid source, and a dressing. Fluid may be drawn from the fluid source to the ultrasonic bubble generator, whereby micro-bubbles and ultrasonic waves may be generated in the fluid before the fluid is instilled to the dressing.

This disclosure includes wound dressings and systems with high-flow therapeutic gas sources for topical wound therapy and related methods. Some dressings, which are configured to be coupled to tissue to facilitate delivery of therapeutic gas to the tissue, comprise a manifold that defines a plurality of gas passageways, the manifold configured to allow communication of therapeutic gas to the tissue; and a gas-occlusive layer configured to be disposed over the manifold and coupled to the tissue such that an interior volume containing the manifold is defined between the gas-occlusive layer and the tissue and the gas-occlusive layer limits escape of therapeutic gas from the interior volume; wherein the gas-occlusive layer includes: a first opening configured to allow communication of therapeutic gas into the interior volume; and one or more second openings configured to allow communication of therapeutic gas out of the interior volume.

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.

Apparatus and methods to treat skin defects include a pump with reservoirs for a pressurization gas and a fluid. Upon activation, the pump generates a gas introduced into the gas reservoir, a movable wall of which displaces a movable wall of a fluid source, thus dispensing the fluid into the dressing to spread throughout irrespective of orientation of the dressing, maintaining a transport fluid (e.g. carrier) in the dressing and in contact with a skin defect being treated. The dressing may have a distribution network, and multiple members, dispensing the fluid into the dressing and in contact with a skin defect being treated.

A multi-action wound dressing for accelerated wound healing by means of multi-therapeutic action is disclosed. The dressing comprises a porous sheet (101); two flexible sheets (102) having a first sheet (103) and a second sheet (104) attached to each other; multichannel conduits (105) or a plurality of single channel conduits; multichannel tubes (106), side adhesive tapes (107) and an optional wound contact layer (108). The porous sheet (101) includes a top planar surface (201), thickness (202) and a bottom uneven surface (203). The bottom uneven surface (203) lies on the surface of the wound and may have surface patterns (204). The pattern (204) may be wavy patterns and/or any other regular and/or irregular surface protrusion that allow intermediate gaps between wound surface and the bottom surface (203) of the porous sheet through which fluid can flow over the wound surface.

The present disclosure relates to a bandage wherein the bandage comprise of a first layer of protective covering, wherein the first layer is removable; a second layer of covering, wherein the second layer of covering is made of a cloth material; a third layer of covering, wherein the third layer is the top most layer of the bandage and together with the second layer forms a support pad; an injection, wherein the injection is present on the second layer of covering; a cylinder, wherein the cylinder is present in the support pad, wherein the bandage is used for delivering a medication to a localized area on a patient's body. The bandage is further used for delivering localized, painless ozone gas treatment to a patient suffering from infectious disease. The bandage is easy to carry and comes in various shapes and sizes.

A method of providing moisture therapy to a subject by applying a moist therapy compress against a treated body portion. The moist therapy compress includes a fluid-permeable shell, a flexible backing fastened to the shell to define an enclosure, and a hydrophilic zeolite fill granules loosely contained within the enclosure. The therapy compress is exposed to a source of moisture to cause absorption of water into the hydrophilic zeolite, and the moisture is delivered from the hydrophilic zeolite through the fluid permeable shell to the treated body portion.

A non-invasive tissue oxygenation system for accelerating the healing of damaged tissue and to promote tissue viability is disclosed herein. The system is comprised of a lightweight portable electrochemical oxygen concentrator, a power management system, microprocessors, memory, a pressure sensing system, an optional temperature monitoring system, oxygen flow rate/oxygen partial pressure monitoring and control system, a display screen and key pad navigation controls as a means of providing continuous variably controlled low dosages of oxygen to a wound site and monitoring the healing process. A kink resistant oxygen delivery tubing, whereby the proximal end is removably connected to the device and the distal end with holes or a flexible, flat, oxygen-permeable tape is positioned at or near the wound bed as a means of applying near 100% pure oxygen to the wound site. The distal end of the tube is in communication with the electrochemical oxygen concentrator and wound monitoring system to communicate oxygen partial pressure and, where appropriate, temperature information. A moisture absorbent dressing is positioned over the distal end of the tubing at the wound site and a reduced moisture vapor permeable dressing system is positioned whereby covering the moisture absorbent dressing, distal end of tubing and wound site creating a restricted or occluded airflow enclosure. The restricted airflow enclosure allows the out-of-the-way control and display unit to provide a controlled hyperoxia and hypoxia wound site for accelerated wound healing.

The invention provides a vacuum tube attachment device for vacuum assisted wound dressings. The device is in the form of a patch that can be attached to the primary wound cover. The patch forms a substantially air-tight seal to the primary wound cover, and a vacuum tube is fixed to the patch such that the patch can be oriented on the wound cover to locate the tube near an opening in the cover to allow vacuum pressure to be communicated to the wound. The patch has an adhesive area around its perimeter for attaching the patch in a substantially air-tight seal to the wound cover at any convenient location on the cover. Several embodiments of the patch are described.
