Tubing retention device

Abstract

Tubing retention systems are described herein. A tubing retention system includes a spigot, a tubing, and a collar. The spigot includes a spigot body and a spigot extension extending from the spigot body, wherein the spigot extension comprises a flared portion opposite to the spigot body and the spigot body and the spigot extension cooperatively define a spigot lumen. The tubing includes an outer surface and a tubing lumen, wherein a coupling portion of the tubing is disposed around the spigot extension, permitting fluid communication between the tubing lumen and the spigot lumen. The collar is disposed radially around the outer surface of the tubing and axially between the flared portion and the spigot body, wherein the collar radially engages the coupling portion of the tubing disposed around the spigot extension to axially and radially retain the tubing with the spigot.

What is claimed is: 
     
         1 . A method, comprising:
 disposing a collar around an outer surface of a tubing;   advancing a coupling portion of the tubing around a spigot extension of a spigot;   advancing the collar toward the coupling portion of the tubing around the spigot extension;   melting a portion of the collar to radially engage the coupling portion of the tubing around the spigot extension; and   axially and radially retaining the tubing with the spigot via the collar.   
     
     
         2 . The method of  claim 1 , further comprising:
 frictionally engaging the outer surface of the tubing at a friction surface of the collar by melting the portion of the collar.   
     
     
         3 . The method of  claim 1 , further comprising:
 advancing the coupling portion of the tubing past a flared portion of the spigot extension.   
     
     
         4 . The method of  claim 3 , further comprising:
 advancing the collar past the flared portion of the spigot extension.   
     
     
         5 . The method of  claim 4 , further comprising:
 radially expanding the collar over the flared portion of the spigot extension.   
     
     
         6 . The method of  claim 1 , further comprising:
 applying a solvent between the coupling portion of the tubing and the spigot extension of the spigot.   
     
     
         7 . The method of  claim 6 , further comprising:
 curing the solvent to bond the tubing and the spigot.   
     
     
         8 . The method of  claim 1 , further comprising:
 extruding a collar stock; and   cutting the collar stock to form the collar.   
     
     
         9 . The method of  claim 8 , further comprising:
 helically winding the collar stock.   
     
     
         10 . The method of  claim 1 , wherein the coupling portion of the tubing comprises a coupling inner diameter equal to or larger than a spigot extension outer diameter. 
     
     
         11 . The method of  claim 10 , further comprising:
 coupling an expander sleeve to the tubing to define the coupling portion.   
     
     
         12 . The method of  claim 1 , further comprising:
 radially expanding the collar at a hinged portion of the collar.   
     
     
         13 . The method of  claim 12 , further comprising:
 melting the portion of the collar to engage the collar, wherein the portion is disposed opposite to the hinged portion of the collar.   
     
     
         14 . A method, comprising:
 disposing a collar with a helical body around an outer surface of a tubing;   advancing a coupling portion of the tubing around a spigot extension of a spigot;   advancing the collar toward the coupling portion of the tubing around the spigot extension;   radially expanding the helical body over a flared portion of the spigot extension;   melting a portion of the collar to radially engage the coupling portion of the tubing around the spigot extension; and   axially and radially retaining the tubing with the spigot via the collar.   
     
     
         15 . The method of  claim 14 , further comprising:
 frictionally engaging the outer surface of the tubing at a friction surface of the collar by melting the portion of the collar.   
     
     
         16 . The method of  claim 14 , further comprising:
 advancing the coupling portion of the tubing past the flared portion of the spigot extension.   
     
     
         17 . The method of  claim 14 , further comprising:
 applying a solvent between the coupling portion of the tubing and the spigot extension of the spigot.   
     
     
         18 . The method of  claim 17 , further comprising:
 curing the solvent to bond the tubing and the spigot.   
     
     
         19 . A method, comprising:
 disposing a collar around an outer surface of a tubing;   advancing a coupling portion of the tubing around a spigot extension of a spigot;   advancing the collar toward the coupling portion of the tubing around the spigot extension;   radially expanding the collar at a hinged portion of the collar;   melting a portion of the collar to radially engage the coupling portion of the tubing around the spigot extension, wherein the portion is disposed opposite to the hinged portion of the collar; and   axially and radially retaining the tubing with the spigot via the collar.   
     
     
         20 . The method of  claim 19 , further comprising:
 frictionally engaging the outer surface of the tubing at a friction surface of the collar by melting the portion of the collar.
