Appl. No.:

09/537195

Inventors:

Minh Quang Hoang - Taylorsville UT
Jonathan Karl Burkholz - Salt Lake City UT
Donald Edward Hunt - Provo UT

Assignee:

Becton, Dickinson and Company - Franklin Lakes NJ

International Classification:

B67D 558

US Classification:

222190, 222180, 2223217, 2223219, 2224641

Abstract:

A foam dispensing device is disclosed. The device includes a container for holding a foamable liquid and having at least one planar surface and a foam generating piston pump removably attached to the container to prevent liquid leaking from the container. The device can dispense foam when substantially the entire quantity of the liquid has been dispensed from the container when the container is in positioned in a first, generally horizontal position, or a second, generally vertical position.

Abstract:

An alcohol based hand surgical scrub, which includes cationic anti-microbial agent preservatives, cationic polymer film-forming agents and a skin emollient, and provides a long term residual, anti-microbial “invisible glove” on the skin. The composition provides an immediate reduction in bacterial microbes. The polymer system creates an invisible film on the skin following solvent evaporation. This invisible film provides a lasting anti-microbial barrier on the skin which acts to prevent microbial growth.

Abstract:

An antiseptic cleaning agent, generally, comprising chlorhexidine acetate and a solvent, such as an alcohol and/or water. The chlorhexidine acetate acts as a highly effective biocide. Additionally, the chlorhexidine acetate allows the cleaning agent to dry without leaving a tacky residue. Where the cleaning agent comprises one or more alcohols, the alcohols may comprise any suitable alcohols, including lower alcohols having from 1 to 6 carbon atoms, such as ethanol and isopropanol. In addition to chlorhexidine acetate, the cleaning agent optionally comprises another non-alcohol biocide, such as triclosan. The cleaning agent can be used in any suitable manner. For instance, the cleaning agent may be impregnated in an absorbent material, such as a towelette, swabstick, or gauze. Additionally, the absorbent material may comprise a positively charged or a non-ionic substance, such as polypropylene or polyester.

Additionally, the chlorhexidine acetate allows the cleaning agent to dry without leaving a tacky residue. Where the cleaning agent comprises one or more alcohols, the alcohols may comprise any suitable alcohols, including lower alcohols having from 1 to 6 carbon atoms, such as ethanol and isopropanol. Where the ratio of ethanol to isopropanol may be from between about 1:1000 to about 1000:1. In addition to chlorhexidine acetate, the cleaning agent optionally comprises another non-alcohol biocide, such as triclosan. The cleaning agent can be used in any suitable manner. For instance, the cleaning agent may be impregnated in an absorbent material, such as a towelette, swabstick, or gauze.
