Filed:

Oct 26, 1983

Appl. No.:

6/545659

Inventors:

Deborah Henderson - Elkton MD
Norman Street - Wilmington DE

Assignee:

W. L. Gore & Associates, Inc. - Newark DE

International Classification:

A61M 1600

US Classification:

12820228

Abstract:

A breathable, laminated, sanitary barrier is provided for use during cardiopulmonary resuscitation (CPR). The laminate comprises a sheet of expanded, porous polytetrafluoroethylene bonded to a substrate material. When placed over a patient's nose and mouth, the barrier enables the CPR practitioner to perform his/her mouth-to-mouth rescue attempt with substantially no reduction in air flow and eliminates direct mouth-to-mouth contact while substantially preventing the transfer of aerosols, bacteria, particles and viruses from practitioner to the patient or mannequin, or vice versa.

Abstract:

The invention comprises a unitized system of garments that prevents particulate matter from passing from the body of the person wearing the garments into the surrounding atmosphere or vice versa. Water vapor or other gases such as air are free to pass through the garment fabric which is a laminate of expanded, porous and gas permeable polytetrafluoroethylene (PTFE) bonded to a porous and gas permeable backing material. Particulate matter is blocked by the very fine pores of the garment. The person is totally enclosed in the garments preferably presenting virtually a 100% external surface of nonlinting PTFE, and passage of water vapor or water vapor and air through the laminate is sufficient to allow breathability. In order to make practical putting the garment on and taking it off, and to eliminate gaps in the garment, separate pieces are required and particulate-proof barriers are required where the separate sections are joined. To ensure the integrity of the total system, high quality jointing is required at every junction between every separate garment piece.
