Title:	Disinfectant delivery system and method of providing alcohol-free disinfection
Abstract:	A disinfectant delivery system and method of providing alcohol-free disinfection to a body to be disinfected, as well as a method of infection reduction by preparation of a patient before an invasive procedure. A blended cloth comprising first fibers and second fibers is provided with the first fibers generally being greater in quantity by weight than the second fibers. A disinfectant solution impregnates the blended cloth, with the disinfectant solution having chlorhexidine gluconate as an active ingredient and having no alcohol. In the method according to the invention, at least one impregnated blended cloth is used to disinfect at least a portion of a body. A plurality of blended cloths can be provided for disinfecting discrete portions of the body. When an invasive procedure is to be performed on a patient, a further method according to the invention of infection reduction comprises using a CHG-impregnated cloth to disinfect at least a portion of the patient at least one day prior to the invasive procedure proximate the location of the invasive procedure.

A method of infection reduction by preparation of a patient before an invasive procedure, comprising a. providing a first blended cloth comprising a fibrous mat impregnated with a first disinfecting solution having chlorohexidine gluconate (CHG) as an active ingredient and having no alcohol, and b. using the first impregnated cloth to disinfect at least a portion of the patient at least one day prior to, and up to several days prior to, the invasive procedure proximate the invasive procedure, c. providing a second blended cloth comprising a fibrous mat impregnated with a second disinfecting solution having chlorohexidine gluconate (CHG) as an active ingredient and having no alcohol, and d. using the second impregnated cloth to disinfect at least a portion of the patient immediately prior to the invasive procedure proximate the invasive procedure, wherein the first blended cloth comprises first fibers and second fibers, with the quantity by weight of said first fibers generally being greater than the quantity by weight of the second fibers, said first blended cloth having an absorbency by weight greater than the weight of said first blended cloth, and wherein the second blended cloth comprises first fibers and second fibers, with the quantity by weight of said first fibers generally being greater than the quantity by weight of the second fibers, said second blended cloth having an absorbency by weight greater than the weight of said second blended cloth. 2. The method according to claim 1, in which the first fibers of the first blended cloth comprise polyester fibers. 3. The method according to claim 1, in which the second fibers of the first blended cloth comprise polyester fibers. 4. The method according to claim 1, in which the first fibers of the second blended cloth comprise polyester fibers. 5. The method according to claim 1, in which the second fibers of the second blended cloth comprise polyester fibers. 6. The method according to claim 1, wherein substantially all of the CHG in the first disinfecting solution is released from the first blended cloth during the method step "b". 7.
