This invention relates to devices and a method promoting the convenient use of hand sterilizing fluids and gels applied to reduce the hand-borne transmission of pathogens. While clean, disinfected hands are widely recognized as a principle means for controlling the spread of infections, disease, and similar health problems to both self and others, the prompt and repeated application of such materials as soap and water or waterless alcohol gels is necessary for maintaining a sanitary hand condition. This is particularly true for nurses, health care providers, veterinarians, elementary teachers, food handlers and others where rapid and continuous movement between patients, clients and tasks provides optimum conditions for cross-contamination. This invention of a convenient, wrist-mounted dispenser of hand sterilizing fluids in a blister package format advances the use of such materials to effectively control the spread of hand-borne pathogens.
