The wound treatment apparatus combines an internal negative pressure (vacuum) pump and an internal positive pressure (compressor) pump connectable to an external oxygen supply for providing both negative pressure wound therapy and hyperbaric oxygen wound therapy to a wound site. The apparatus also includes a user interface operatively connected to an electronic controller that monitors and actuates the vacuum and compressor pumps. The user interface and controller enables the apparatus to provide multiple modes of operation and the ability to selectively change between negative pressure therapy operational modes and hyperbaric oxygen operational modes.

The present invention provides a method for promoting hair growth and improving white hair condition, including supplying hydrogen and oxygen to scalp and hair. The present invention further provides a hear wearable device or a hairdressing apparatus for promoting hair growth and improving white hair condition, including a gas supply device, wherein the gas supply device includes a separation layer, a hydrogen-producing composition wrapped in the separation layer, and an oxygen-producing composition wrapped in the separation layer; the hydrogen-producing composition includes: (1) a metal hydroxide and aluminum powder, or (2) a metal peroxide and aluminum powder, or (3) a hydride, or (4) a combination of the three above; and the oxygen-producing composition includes a metal peroxide.

The invention provides a wound-treating gas composition and a wound-treating apparatus usable with a novel wound-treating method making use of hydrogen sulfide. The wound-treating gas composition contains hydrogen sulfide in a proportion of 20 ppm or lower, and the wound-treating apparatus includes a cover or container to which the wound-treating gas is fed.

A system for delivery of gas to a tissue, comprises: a first container containing the gas, an applicator having a distal end arranged to deliver the gas to the tissue, a second container containing a purging gas, and; and a flow control system for controlling flow of gas. The system also comprises a three-port valve having a first port for receiving the gas from the first container, a second port for receiving the purging gas from the second container, and a third port in fluid communication with the applicator. The valve is switchable between a first state at which the first port fluidly connects to the third port, and a second state at which the second port fluidly connects to the third port.

A method for treating a wound includes the steps of: (1) introducing ambient air into an oxygen concentrator that increases an oxygen concentration of the ambient air and forms a first output gas; (2) introducing the first output gas into a corona discharge generator that transforms the first output gas into a second output gas by converting portions of the concentrated oxygen into reactive oxygen species (ROS), and converting portions of the nitrogen gas into nitrogen reactive species (NRS); and (3) delivering the second output gas into a multi-gas compartment within a treatment device in which the wound is positioned.

Methods, systems, and devices are provided for generating a mist. In one embodiment, a fluid delivery device is provided that includes a housing, a fluid vaporizer disposed within the housing and configured to receive fluid and to produce an aerosol mist of liquid particles from the fluid, and a pump configured to accelerate the aerosol mist produced by the fluid vaporizer. Methods are provided for producing a mist, and the methods can include delivering a fluid to a fluid vaporizer that generates a first mist. The fluid vaporizer delivers the mist to a pump that generates a second mist from the first mist.

A multifunctional central suction system capable of remote monitoring includes a flow measurement device and a controller, wherein a negative pressure port of the flow measurement device is connected to a negative pressure air nozzle of the controller via a gas pipe; the flow measurement device includes a measurement mechanism and a liquid bottle; the negative pressure port is arranged on the liquid bottle; a first Bluetooth communication module is provided on the measurement mechanism; a communication module is provided in the controller; the communication module includes a second Bluetooth communication module and a WiFi communication module; and the first Bluetooth communication module on the measurement mechanism is in communication connection with the second Bluetooth communication module in the controller.

Therapeutic dressings, a process for the preparation of a gasotransmitter, and various methods are disclosed. A therapeutic dressing according to an embodiment includes a composition including an organic electrochemical mediator configured to reduce a gasotransmitter salt, and the gasotransmitter salt converting into a gasotransmitter upon reduction; a carrier adapted to contain the composition; and a bimetallic cell delivering current to the composition.

An apparatus and method for cleansing and applying therapy or prophylaxis to wounds, in which irrigant fluid, which may contain a physiologically active material, and wound exudate from the dressing are moved by a device for moving fluid through a flow path which passes through the dressing. A means for fluid cleansing may also be provided to recirculate fluid back to the dressing. The cleansing means removes materials deleterious to wound healing, and the cleansed fluid, still containing materials that are beneficial in promoting wound healing, is returned to the wound bed. The apparatus may also provide means for distributing such materials in a precise and time-controlled manner over the wound bed. It may also contain a means for providing simultaneous aspiration and irrigation of the wound.

A contactless wound treatment barrier assembly carrying a primed wound treatment composition carrier is secured to a patient's skin at a location encapsulating a wound. A wound treatment composition is emitted from the carrier in a gaseous state. The gaseous emission remains within an interior volume of the wound treatment barrier assembly. The design of the wound treatment barrier assembly can minimize any contact between a body of the wound treatment barrier assembly, the wound treatment composition carrier and the wound. An insole carrying a wound treatment composition (such as elemental Iodine) can be used in any of a variety of forms. The insole would deliver the treatment composition. The insole can be designed to provide contactless or contact delivery of the treatment composition.
