ABSTRACT:
A process and system is provided for making a connection between two fluid-filled plastic tubes that ensures total containment of potentially dangerous fluids and maintaining sterility of the connection. The tubes are folded to remove all fluid from the weld site and positioned to cause the connection to take place in this fluid free zone. Each folded section is first cauterized to create a bacteria free zone, the tubes are slit in the zone, and cauterized a second time to insure sterility and melt the tube ends. The tubes are urged together and as the thermoplastic resin cools, a totally contained, sterile weld is formed.
