Abstract: A wound therapy device is disclosed. The wound therapy device may include a housing for covering at least a portion of a wound and for sealing to a body surface of a patient. The housing may also include a liquid collector for retaining liquid therein and a vacuum connection for coupling to a vacuum source. The vacuum connection may be in gaseous communication with the liquid collector. The vacuum connection may be separated from the liquid collector by a liquid barrier.

Abstract: A volatile substance delivery system includes a volatile substance container to contain a volatile substance, a volatile substance delivery structure, and a volatile substance drop delivery system to deliver a drop of the volatile substance to the volatile substance delivery structure for delivery to an ambient environment.

Abstract: 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.

Abstract: A system facilitates creating a controlled hydrogen rich environment around a patient. The system includes an enclosure, at least one opening, and a hydrogen source. The enclosure forms an internal space to at least partially enclose a body part of the patient. The opening is defined within the enclosure to allow a portion of the body part of the patient to extend out of the internal space of the enclosure. The opening is further configured to form a seal around the body part that extends out of the internal space of the enclosure. The hydrogen source delivers hydrogen gas into the internal space of the enclosure.

Abstract: A negative pressure wound therapy (NPWT) system creates and maintains a sub-atmospheric pressure within a sealed wound environment for the purpose of healing wounds. The NPWT system includes a wound interface material, a housing, an osmotic membrane, and an evacuation port. The wound interface material contacts a wound region and absorbs exudate from the wound region. The housing defines a cavity in an interior space of the housing. The osmotic membrane is coupled to the wound interface material to transfer a fluid of the exudate from the wound interface material to the cavity of the housing. The evacuation port is also coupled to the wound interface material to facilitate passage of a gas out of the wound interface material to create a negative pressure at the wound region.

Abstract: A dermal delivery apparatus includes a pad having a surface to interface with an outer layer of skin. The dermal delivery apparatus also includes a micro structure coupled to the pad and configured to penetrate and deliver an agent beneath the outer layer of skin. The dermal delivery device also includes a base at least partially surrounding the micro structure. The base is coupled to the pad and protrudes away from the surface of the pad to apply surface tension to the skin.

Abstract: Apparatus and methods to treat skin defects include a pump with reservoirs for a pressurization gas and a fluid, the fluid loaded at a factory and sealed or filled at point of use through a valve, septum, or the like. 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. Delivery may be periodic, constant, programmatically controlled, or manual. A dressing may maintain intimate contact, a transport fluid, and a controllable concentration of active ingredient against a skin defect. Apparatus and methods to replenish a dressing with a therapeutically effective concentration of a fluid deliver a fluid carrier containing an active ingredient.

Abstract: A cushion adapted to reduce heat and moisture from a wheelchair user's body, including a cushion member having a compressible material that permits air and moisture to flow through the cushion member. The cushion also includes an air and water permeable cover adapted to receive the cushion member. The cover includes an interface member having an outer layer formed of a hydrophobic material, an inner layer formed of a hydrophilic material, and a spacer layer having fibers positioned between, and generally perpendicular to, the outer and inner layers.
