Abstract
Plastic, natural or synthetic rubber surgical appliances such as gloves, condoms, drains, catheters and tubing are coated with a nontoxic chemical formulation to inhibit sticking during storage and to ease the installation of the device. The coating disclosed herein is a water soluble nontoxic chemical compound that incorporates Na (sodium) or K (potassium) in varying chemical combinations with carbonates, acetates, bicarbonates, acetate trihydrates and citrate dihydrate.
Claims22
The process of applying to plastic, natural or synthetic rubber surgical devices a nontoxic lubricating coating which does not cause adverse reactions in animals or human patients, which eases installation, and which prevents self-adhesion in storage of said devices, which comprises:
- coating the surfaces of said devices with a dry coating which consists of a chemical compound of one alkali metal selected from the group consisting of sodium (Na) and potassium (K) in chemical combination with a radical selected from the group consisting of carbonate (CO.sub.3), bicarbonate (HCO.sub.3), acetate (C.sub.2 H.sub.3 O.sub.2), acetate trihydrate (C.sub.2 H.sub.3 O.sub.2.3H.sub.2 O), and citrate dihydrate (C.sub.6 H.sub.5 O.sub.7.2H.sub.2 O).
Plastic, natural or synthetic rubber surgical devices whose surfaces are coated with a dry layer of a chemical compound of one alkali metal selected from the group consisting of sodium (Na) and potassium (K) in chemical combination with a radical selected from the group consisting of carbonate (CO.sub.3), bicarbonate (HCO.sub.3), acetate (C.sub.2 H.sub.3 O.sub.2), acetate trihydrate (C.sub.2 H.sub.3 O.sub.2.3H.sub.2 O), and citrate dihydrate (C.sub.6 H.sub.5 O.sub.7.2H.sub.2 O) as a nontoxic lubricating coating to ease installation and to prevent self-adhesion in storage.
