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.

Claims

exact text as granted — not AI-modified
What is claimed is:  
     
         1 . A disinfectant delivery system, comprising 
 a. a blended cloth comprising first fibers and second fibers, with the quantity by weight of said first fibers generally being greater than the quantity by weight of said second fibers, said blended cloth having an absorbency by weight greater than the weight of said blended cloth, and    b. a disinfectant solution impregnating said blended cloth, said disinfectant solution having chlorhexidine gluconate (CHG) as an active ingredient and having no alcohol.    
     
     
         2 . A disinfectant delivery system according to  claim 1  in which said fibers are blended by entanglement, and comprise polyester.  
     
     
         3 . A disinfectant delivery system according to  claim 1  in which said first fibers have one thickness and said second fibers have a thickness different from said one thickness.  
     
     
         4 . A disinfectant delivery system according to  claim 3  in which said one thickness is about 1.2 to 1.5 denier.  
     
     
         5 . A disinfectant delivery system according to  claim 3  in which said different thickness is about 4.75 denier.  
     
     
         6 . A disinfectant delivery system according to  claim 1  in which said fibers have a length of from about 1.5-3 inches.  
     
     
         7 . A disinfectant delivery system according to  claim 1  in which said CHG is about 1.80 -2.20 percent by weight of said disinfecting solution.  
     
     
         8 . A method of providing alcohol-free disinfection to a body to be disinfected, comprising 
 a. providing a blended cloth comprising first fibers and second fibers, with the quantity by weight of said first fibers generally being greater than the quantity by weight of said second fibers, said blended cloth having an absorbency by weight greater than the weight of said blended cloth,    b. providing a disinfecting solution having chlorhexidine gluconate (CHG) as an active ingredient and having no alcohol,    c. impregnating said cloth with said disinfecting solution, and    d. using the impregnated cloth to disinfect at least a portion of the body.    
     
     
         9 . The method according to  claim 8 , in which step “b” comprises providing CHG in about 1.80-2.20 percent by weight of said disinfectant solution.  
     
     
         10 . The method according to  claim 8 , in which step “a” comprises providing a plurality of said blended clothes, step “c” comprises impregnating all of said blended cloths, and step “d” comprises using each impregnated cloth to disinfect a discrete portion of the body.  
     
     
         11 . The method according to  claim 10 , including the step, before step “d”, of packaging the impregnated cloth in a resealable package.
