ABSTRACT:
There is disclosed herein an improved needle assembly or fistula set which includes a hollow metal needle, a larger plastic fluid-carrying conduit, and plastic spacers between the needle and the conduit. The conduit and spacers are heat sealed to each other so as to provide a fluid-tight junction with the needle.
A method for heat sealing the fistula set is also disclosed. In that method, the needle is used as one electrode and the other electrode includes jaw-like members which engage and surround the conduit at the junction where the heat seal is to be formed. During the heat sealing operation, the conduit and needle are maintained in substantial coaxial alignment so as to assure coaxial alignment thereafter.
A fixture or tooling apparatus is also disclosed for effecting heat sealing and assuring substantial coaxial alignment.
