  • Publication number: 20110066096
    Abstract: Devices and methods aimed at shortening the time required for healing open wounds are disclosed. The tissues adjacent to wounds are expanded and/or stretched medially by means of an actuator which compressed by vacuum exerts traction on adjacent skin or tissues by means of an adhesively applied circumferent or transverse flange, thus reducing the size of the wound. The degree of vacuum, and traction, may be varied according to demand and applied continuously, cyclically or intermittently. Active treatment of the wound may be accomplished concomitantly by means of a conduit through the said actuator.

  • Patent number: 6855133
    Abstract: A housing is secured to an area of skin to allow suction to be applied to a local area of skin through an aperture. After formation of a suction blister, a blade is actuated to sever a suction cup thereby detaching the means for creating suction at the aperture and at the same time removing the roof of the suction blister to expose an area of dermis from which the skin's epidermis has been removed. A rotatable portion of the apparatus is then moved into a position in which a port communicates with a compartment within the rotatable portion. The compartment may contain a reservoir of fluid substance to be transdermally absorbed or may contain means for taking a sample of exudate produced at the exposed dermis. A modified apparatus has means for applying suction to the exposed dermis to enhance the rate at which exudate is formed and for handling a sample of exudate for analysis. Transdermal delivery and sampling are thereby achieved non-invasively and without the impediment of the skin's epidermis.

  • Patent number: 6254580
    Abstract: There is disclosed an apparatus (1) for use in a suction blister technique of sampling fluid from the human or animal body. The apparatus (1) comprises a cup (2) defining a chamber and having a rim portion (3) defining an aperture (5) communicating with the chamber. An annular flange (6) extends outwardly from the rim portion (3) whereby in use the flange (6) is sealingly attached to the body such that an area of skin closes the aperture (5). A ducted portion (11) is connected to the cup (2) and defines duct (12) which communicates with the chamber. The cup (2) further comprises a roof (4) which merges with the rim portion (3) and is formed of a resiliently deformable material having a shape memory which urges the roof (4) into an expanded configuration in which the roof (4) is held clear of the aperture (5). The roof is however deformable to a collapsed configuration in which it is proximal to the aperture (5).
