ABSTRACT:
A device and method for use in forming an access port, and also in forming a leakproof seal between a conduit (e.g., a catheter tube) and a thermoplastic film (e.g., the wall of an ostomy bag, wound cover pouch, or similar pouch). The device includes internal and external coupling rings adapted to be locked together with a collar of film material clamped therebetween. An elastomeric nipple has an enlarged proximal end portion similarly clamped between the coupling rings and contributes in forming fluid-tight seal between the parts. The method of use of the device is also disclosed, such method including the insertion of a piercing element into the opening of the internal ring to form a two-piece piercing assembly, followed by the step of utilizing that assembly to pierce a flexible plastic film and form a collar of plastic material about the outer surface of the internal ring.
