Patent number: 6488665Abstract: The present invention provides antimicrobial skin-preparation delivery systems useable to disinfect a surgical site for surgery. The delivery systems include an antimicrobial alcohol gel formulation contained within a sealed, flexible container and a gel formulation dispenser connected to the container. The gel formulation dispenser includes a container connector connected to the flexible container and a gel applicator having a sealed piercing member which is slidably engaged with the container connector. An applicator pad is porous and also has enlarged holes for passage of the gel formulation. The gel formulation dispenser pierces a seal in the container and delivers the antimicrobial alcohol gel formulation from the container to the surgical site.

Patent number: 6393843Abstract: The invention relates to extended life thermal packs. In one embodiment, the thermal pack comprises a container having a first thermally reactive chemical solute therein, a rupturable solvent packet containing a solvent, and a rupturable solute packet containing a second thermally reactive chemical solute in the solute packet. The solutes are chemically separated until time of use and are different from one another. The chemical separation of solutes until time of use in combination with the structure of the thermal pack structure afford both extended duration of thermal effect by the pack and afford the user with increased control by permitting optional sequential combination of the reactants. The thermal reaction produced by the combination of solute and solvent can be either endothermic or exothermic and therefore can be used to apply cold or hot therapy, respectively.Type: GrantFiled: January 24, 2001Date of Patent: May 28, 2002Assignee: Allegiance CorporationInventor: Daniel J.
