Abstract
A self-contained, self-lubricating catheter assembly is provided. A receptacle formed of two opposed flexible walls includes a main chamber and a lubrication chamber separated by a passage. A lubricant is provided in the lubrication chamber. A catheter is advanced from the main chamber through the lubrication chamber and picks up lubricant as it is passes through the lubrication chamber. A catheter grasping mechanism, located proximate the exit from the lubrication chamber, permits advancement of the catheter out of the receptacle and resists movement of the catheter back into the receptacle. The receptacle also includes one or more finger holes therethrough to allow the user to retain the receptacle on one or more fingers, thereby allowing the hand to more readily position the receptacle during use while advancing the catheter.
