Publication number: 20020161345Abstract: The present invention is directed to a wound splashguard which includes a wound cover for blocking fluid splatter, and an adjustable fluid source mount for allowing movement of a fluid source from a first position to at least a second position to re-direct a fluid spray relative to the wound while the splash guard is maintained in a substantially stationary position. The invention is further directed to a method of using the adjustable mount which allows the practitioner to move the fluid source so that the fluid spray can irrigate a larger portion of a wound without having to move the splashguard thereby increasing irrigation efficiency and reducing the risks of needle stick injury.Type: ApplicationFiled: April 27, 2001Publication date: October 31, 2002Inventor: Matthew McMillin

Publication number: 20020156436Abstract: The present invention is directed to treatment assemblies and, more specifically, to a treatment assembly having two pockets, one containing a fluid, such as a treatment, and an absorbent material, and the other containing an absorbent material. In one embodiment, the present invention is directed to a treatment assembly, including a first layer and a second layer joined to the first layer to define a first pocket and a second pocket substantially sealed from one another. The assembly further includes a first absorbent material and a fluid in the first pocket and a second absorbent material in the second pocket. The assembly may be used in a method of treatment by removing the first absorbent material from the first pocket and applying the fluid to a treatment area with the first absorbent material. The method may further include removing the second absorbent material from the second pocket and drying the treatment area with the second absorbent material.Type: ApplicationFiled: April 18, 2001Publication date: October 24, 2002Inventor: Jeffrey Kerchner

Patent number: 6464672Abstract: A multilayer composite material and method for evaporative cooling of a person employs an evaporative cooling liquid that changes phase from a liquid to a gaseous state to absorb thermal energy. The evaporative cooling liquid is absorbed into a superabsorbent material enclosed within the multilayer composite material. The multilayer composite material has a high percentage of the evaporative cooling liquid in the matrix. The cooling effect can be sustained for an extended period of time because of the high percentage of phase change liquid that can be absorbed into the superabsorbent. Such a composite can be used for cooling febrile patients by evaporative cooling as the evaporative cooling liquid in the matrix changes from a liquid to a gaseous state to absorb thermal energy. The composite can be made with a perforated barrier material around the outside to regulate the evaporation rate of the phase change liquid.Type: GrantFiled: October 26, 1999Date of Patent: October 15, 2002Inventor: Theresa M.
