Self contained urethral catheter assembly with lubricating chamber
First Claim
1. A self-contained, self-lubricating catheter assembly comprising:
- a receptacle comprising two opposed flexible, sheet-like walls extending from a closed distal end to a proximal end, a main chamber and a lubrication chamber formed between the flexible, sheet-like walls, a passage separating the main chamber and the lubrication chamber, and an exit from the lubrication chamber formed in the closed distal end of the walls of the receptacle;
a lubricating material disposed in the lubrication chamber; and
a catheter disposed within the receptacle.

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.
