ABSTRACT:
A self-contained swab unit comprises a cylindrical plastic tube having a foam rubber swab capping one end. The tube is closed at the opposite end by a heating and crimping process. A cleansing or sterilizing solution is loaded into the tube. The tube is sealed by a plug having a diameter slightly larger than the inside diameter of the cylinder, so that the solution is sealed away from the foam rubber swab when not in use. Squeezing the tube causes the plug to pivot in relation to the wall of the tube so that the seal is broken and liquid may saturate the swab. Releasing the squeeze pressure on the tube causes the plug to pivot back into a partial seal so that the amount of fluid used in swabbing can be controlled.
