| Abstract: | A swivel connector for infusing liquids into catheterized animals is described. The connector turns so freely that restraints and strain relief for the catheter are unnecessary. A cylindrical acrylic body and nylon cap screw hold a rubber O ring in place, and a length of needle tubing rotates within the O ring. The only friction in the swivel is between the needle tubing and the interior of the O ring. Construction time is about 1 h. Swivels of this design have provided trouble-free service for 3 years. |
