Abstract
A liquid applicator for applying a liquid to a surface. The applicator includes a hollow body comprising a wall defining an internal chamber having a closed end and an open end. The applicator further includes a felted polyurethane foam coupled to the open end of the hollow body and an alcohol-based antiseptic solution dispersed within the polyurethane foam. The polyurethane foam has a flatwise tensile strength of at least 1.0 lbf*in/(in2 of foam).

A liquid applicator for applying a liquid to a surface, the liquid applicator comprising:
- a hollow body comprising a wall defining an internal chamber having a closed end and an open end;
- a felted polyurethane foam coupled to the open end of the hollow body;
- and
- an alcohol-based antiseptic solution dispersed within the polyurethane foam;
- wherein the polyurethane foam has a flatwise tensile strength of at least 1.0 lbf*in/(in2 of foam).
A method of preparing a site on skin of a patient, the method comprising:
- providing a liquid applicator, comprising;
- a hollow body comprising a wall defining an internal chamber having a closed end and an open end;
- a felted polyurethane foam coupled to the open end of the hollow body;
- and
- an alcohol-based antiseptic solution dispersed within the polyurethane foam,
- wherein the polyurethane foam has a flatwise tensile strength of at least 1.0 lbf*in/(in2 of foam);
- and
- scrubbing the site with the felted polyurethane foam for a period of at least one minute.
A method of making a felted polyurethane foam, the method comprising:
- providing a polyurethane foam;
- compressing the foam from one-half (½) to one-twentieth ( 1/20) of its initial thickness;
- subjecting the polyurethane foam to a temperature of no less than 430° F. and no more than 450° F. for at least 5 minutes.
