Abstract: Articles of protective wear are normally designed to protect a wearer against one or one group of hazardous materials such as chemical warfare agents. Such chemical warfare protective wear is normally made out of a butyl rubber as butyl rubber provides favorable impermeation protection against a wide variety of both chemical and biological warfare agents while having excellent physical properties. However, the protection provided by butyl rubber based protective wear is seriously reduced when exposed to hydrocarbons as the butyl rubber based protective wears' impermeation integrity is severely impaired. This problem is solved by using an article of protective wear which has a multilayer/multipolymer configuration so that enhanced protection against more than one type of material, such as hydrocarbons and chemical warfare agents, is provided.

Abstract: Various methods of forming a chemical barrier against the transmission of disease-causing microbes and other harmful agents through a membrane fashioned of latex or other material. In one method, the latex material is provided with microbe sterilization properties by deforming the latex material from a relaxed condition such that the pores therein are deformed, then washing the deformed latex material with a biocide, which is entrapped in the pores, and then relaxing the latex material. Alternatively, instead of washing the deformed latex material with the biocide, the biocide may be mixed directly with the liquid latex preferably along with a buffer agent and then the liquid latex can be cured. In yet another method, the latex material is treated with a silicone, protein or high molecular polyion to form a water resistant surface.

Abstract: A process for imparting enhanced antimicrobial properties to medical devices, and particularly surgical and examination gloves, and to such gloves produced by the process. The process involves partially forming the gloves by dipping glove molds into a latex composition, for example, and prior to curing or heating to final form, dipping the already coated forms into a second composition containing an antimicrobial agent, and thereafter curing or heat setting the finally produced glove prior to stripping from the form. Alternatively, the antimicrobial composition can be additionally or independently applied to a cured glove before stripping. The result is a glove which prevents, or decreases the potential of, cross-contamination between the glove users and patients because it will kill or reduce the susceptible microorganisms prior to or after penetration of the basic material forming the glove.

Abstract: A kit comprises a tray with a well for a tourniquet, a dressing to use with a medical device inserted into a blood vessel. An antimicrobial treatment in the well disinfects an area of skin through which the medical device punctures the vessel. A pair of juxtaposed gloves with the finger ends, the hand parts and the cuff portions against one another are rolled up along their longitude from their fingers to their cuffs driving out air entrapped within the gloves. The process of rolling from the fingers to the cuffs leaves the cuffs of each glove at the periphery of the rolled generally cylindrical gloves for access to the inside of each when donning. A method for rolling gloves into a relatively cylindrical package, includes setting the gloves side by side with the finger ends, the hand parts, and the wrist or cuff portions juxtaposed. The finger portions are gathered into an axial bundle and rolled from the finger ends toward the palm or back hand parts driving out air within the gloves.
