An outer housing includes a user contact surface with protrusions for penetrating biofilms of the wound and delivering oxygen produced by an onboard oxygen generating subsystem which electrochemically generates oxygen using an onboard power supply. The user contact surface and the protrusions are gas permeable to absorb and transmit generated oxygen into the wound to improve healing or treat the condition.

A wound therapy device and method includes a skin contacting element, a reactor, and a reactor housing element. The skin contacting element is configured for covering an associated tissue site, the reactor for creating a pressure condition at the associated tissue site upon actuation thereof, and the reactor housing element for accommodating the reactor. The skin contacting element has a skin contacting side and an interface side, which is opposite the skin contacting side. The reactor housing element has a lower affixing side and an upper side, which is opposite the lower affixing side.

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.

An interactive skin treatment and management device having a housing and a fluid basin coupled to the housing. The device can further include a fluid atomizer coupled to the housing, configured to atomize fluid from the fluid basin, and a computing display coupled to the housing. Here, the computing display is configured to receive input from a user. In addition, the housing can also include a lighting unit disposed around the computing display, and a heating or cooling element disposed within the housing. The housing of the device may also include a receptacle for receiving a capsule or container and a tube for releasing and dispensing the contents of the capsule or container, among other features.

A shape compliant wearable Photo-Dynamic Therapy (PDT) pad comprises an outer layer having an outer surface adapted to be exposed to the ambient, an inner layer having an inner surface adapted to be in contact with a body of a user, a metallic sheet provided between the outer layer and the inner layer, the metallic sheet being shape compliant, and a plurality of Light Emitting Diodes (LEDs) provided between the inner layer and the outer layer.
