Abstract: A reduced pressure treatment appliance is provided for treating a wound on the body of a patient. In some embodiments, the appliance comprises an overlay, which is further comprised of cup members that may be detached or cut away from the overlay so that the overlay can be adjusted in size and shape. Also, in some embodiments, the overlay is further comprised of a pressure venting valve to maintain a predetermined level of reduced pressure at the site of the wound. In other embodiments, the wound treatment appliance also includes a vacuum system to supply reduced pressure to the site of the wound in the volume under the overlay. In yet other embodiments, the treatment appliance also includes wound packing means to prevent overgrowth of the wound or to encourage growth of wound tissue into an absorbable matrix comprising the wound packing means. In still other embodiments, a suction bulb may be used to provide a source of reduced pressure to an overlay that covers the wound.

Abstract: A reduced pressure treatment appliance is provided for enclosing and providing reduced pressure treatment to a portion of a body of a patient. The reduced pressure treatment appliance may be used to treat wounds and other conditions, such as lymphedema, varicose veins, venous insufficiency and stasis, and other infirmities. In some embodiments, the appliance comprises an enclosure that encloses the portion of the body to be treated for purposes of applying a reduced pressure to the enclosed portion of the body. In other embodiments, the wound treatment appliance also includes a vacuum system to supply reduced pressure to the portion of the body to be treated in the volume under the enclosure. In yet other embodiments, the treatment appliance also includes wound packing means to prevent overgrowth of the wound or to encourage growth of wound tissue into an absorbable matrix comprising the wound packing means.

Abstract: A gas sensor and method for manufacturing a gas sensor is provided. In order to increase the selectivity and the sensitivity to a gas to be measured, a gas-sensitive gallium oxide layer of a gas sensor is coated with a filter layer that comprises silicon dioxide. In an alternative embodiment, the gallium oxide layer can be coated with a gas-sensitive metal oxide layer made of titanium oxide, aluminum vanadate, tungsten oxide or tantalum oxide.
