A system and method for providing oxygen saturated water or other oxygen saturated solution to a wound or body part is provided wherein the system includes a vessel containing a relatively stable aqueous solution having a dissolved oxygen content of at least 18 mg/L.

A composition for healing or improving skin includes a fabric or material impregnated with an oxygen generating material. The fabric may include a first side in contact with the skin for providing oxygen to the skin and a second side between the oxygen generating material and the air surrounding the skin to form a barrier for retaining heat and inhibiting evaporation.

The wound dressing apparatus facilitates administration of combined negative pressure and positive pressure treatment at a wound site. The wound dressing apparatus includes a wound dome having a substantially hollow dome interior, a manifold that is in fluid communication with the dome interior, a first passage adapted to connect to a negative pressure source to the dome interior, and a second passage adapted to connect to a positive pressure source to the manifold.

A graphene nano-steam generator and a beauty instrument are provided. The graphene nano-steam generator includes a coarse steam channel, a nano-steam channel and a high-voltage power supply device. The coarse steam channel is connected to a coarse steam manufacturing device and the nano-steam channel. The coarse steam channel is provided with a steam sieving device, and an end of the coarse steam channel is provided with a first electrode and a second electrode. The high-voltage power supply device is coupled to the first electrode and the second electrode. The high-voltage power supply device supplies high-voltage electricity to the first electrode and the second electrode, and forms a high-voltage arc discharge between the first electrode and the second electrode, thus the coarse steam molecular group flowing through is ionized by the high-voltage arc to generate a large amount of active nano-scale steam to be flowed out from the nano-steam channel.

A system for negative pressure and hypoxic tissue therapy including a chemical pump assembly, a dressing to cover a tissue site, a plurality of hoses, and a cover layer to cover a portion of the dressing. Each hose is configured to fluidly connect the dressing to the assembly. Oxygen flows from the dressing to a reactor in the assembly where the oxygen is consumed by the reactor. The hoses have different cross-sectional areas and selectable lengths, and these can be selected to provide a desired amount of oxygen around the tissue site. The cover layer has less permeability to air that does the dressing, nd can be used to cover a portion of the dressing to inhibit the permeation of air through the dressing and thus provide the desired amount of oxygen around the tissue site.

Heads for an aerosol container are disclosed. The head comprises a handle body having a base configured to be coupled to the aerosol container, an outlet, a flexible tube housed within the handle body. The flexible tube is configured to provide fluid communication between the container exit of the aerosol container and the outlet. And the head further comprises an elastically deformable actuator comprising a lever arm, and a coupling portion integrally formed with the lever arm and configured to be mounted around the flexible tube, wherein the coupling portion is further configured such that when the lever arm is deformed by a user, the coupling portion actuates on the valve body of the aerosol container. Aerosol containers comprising such heads and kits for treatments skin lesions are also disclosed.

An apparatus for treating a tissue site includes a dressing, an oxygen source, a valve, and a negative-pressure source. The dressing is configured to be sealed around the tissue site. The oxygen source is fluidly coupled to the dressing and configured to provide a low flow of oxygen. A first port of the valve is fluidly coupled to the dressing and the valve moves between a closed position preventing flow through the valve and an open position permitting flow through the valve. The negative-pressure source is fluidly coupled to a second port of the valve and provides negative pressure to the second port of the valve at a non-therapeutic level. The valve separates the negative-pressure source from the dressing and selectively opens when a positive pressure is applied on an upstream side of the valve.

An orthopedic spinal injury therapy device. The device comprises a lying plate, an inflatable bag is provided in the middle of the lying plate, a straight slot is formed in one side of the inflatable bag, supporting plates are vertically connected to both sides of the bottom end of the lying plate, a sliding rod is horizontally arranged between the supporting plates, a nut block and a movable block are connected to both ends of the sliding rod respectively, a threaded rod is vertically connected into the nut block, a fixed rod vertically penetrates through the movable block; the upper ends and the lower ends of the threaded rod and the fixed rod are fixed to side walls of the corresponding supporting plates by mounting blocks, a hollow-square sliding block is slidingly provided on the sliding rod, and a mounting plate is connected to the top of the sliding block.

A wound treatment system includes a housing. A processor is located in the housing. A pressure monitoring system is coupled to the processor. A power delivery system is located in the housing and coupled to the processor. An oxygen concentrator is located in the housing and coupled to the power delivery system. The oxygen concentrator includes a plurality of oxygen outlets. The processor is configured to receive pressure information from the pressure monitoring system that is indicative of a pressure in a restricted airflow enclosure provided by a dressing and located adjacent a wound site; and use the pressure information to control the power provided from the power delivery system to the oxygen concentrator in order to control an oxygen flow created by the oxygen concentrator and provided through one of the plurality of oxygen outlets to the restricted airflow enclosure.
