Abstract: Hemostatic adhesive bandages are disclosed wherein a very thin coating of a high molecular weight polyethylene oxide is applied to the surface of the perforated plastic film wound release cover of an adhesive bandage, in a manner compatible with commonly used high speed production techniques and equipment, which stop the bleeding faster when applied to minor cuts.

Abstract: A method of improving the wet-strength characteristics of a plaster of Paris cast is disclosed. The cast bandage is immersed in dip water which contains 2%-15% by weight of a fluorochemical or the fluorochemical is applied to the finished cast. The fluorochemical is dispersed in the water by a nonionic or cationic surfactant. The resulting cast has improved water-resistant properties.

Abstract: A thermometer including a heat sensitive material which undergoes a reversible visible change from a crystalline solid to a viscous mass at a predetermined temperature, said heat sensitive material comprising an individual or mixture of low molecular weight organic compounds and a polymer, said polymer being present in said mixture in an amount, effective to retard the crystallization of said organic compound between temperatures of from about room temperature to said predetermined temperature. Preferably a plurality of discreet heat sensitive materials each of which undergoes a visible change at a different predetermined temperature are supported on either a flat sheet or round cylinder which may be a dark transparent filter material. The heat sensitive materials are covered by a light transparent filter material which is preferably yellow. In the most preferred embodiment of the instant invention, said heat sensitive materials are contained in the compartments above perforations of a perforated sheet.
