Method of molding a connector and tubing assembly

Abstract

A connector and tubing assembly including a multi-lumen molded connector having at least three flexible tubes also molded into the connector. The connector may be “Y” shaped and include three flexible tubes. A process of making the connector and tubing assembly involves forming a first part of the connector with two tubes molded therein and then removing an internal mold member prior to molding the final connector portion and third tube in place.

1 - 13 . (canceled) 
   
   
       14 . A method of joining at least three flexible, silicone tubes each having an interior surface and a free end, the method comprising:
 supporting the at least three free tube ends in a cavity defined by a mold;   disposing at least a portion of at least one rod assembly into contact with at least a portion of the interior surface of the free tube ends;   disposing liquid silicone in the cavity into contact with the free tube ends and exposed portions of the rod assembly;   curing the liquid silicone to provide a connection between the tubes; and   removing the rod assembly to provide smooth flow path within the connection between the tubes.   
   
   
       15 . The method of  claim 14 , wherein the rod assembly includes at least first, second and third rod members. 
   
   
       16 . The method of  claim 15 , wherein the rod members are joined together in the form of a “Y”. 
   
   
       17 . The method of  claim 14 , wherein the rod assembly is fabricated from a metal. 
   
   
       18 . The method of  claim 14 , wherein the rod assembly is fabricated from stainless steel. 
   
   
       19 . The method of  claim 14 , wherein the rod assembly is fabricated from low density polyethylene. 
   
   
       20 . The method of  claim 14 , wherein the step of removing the rod includes pressurizing at least one of the tubes with a gas. 
   
   
       21 . The method of  claim 20 , wherein the rod is fabricated from a non-silicone material.
