Title: Ball valve
Inventor: DI PALMA GIORGIO
IPC: A61M5/168
Filed: 1990-10-05
Granted: 1993-10-26
Abstract: ABSTRACT    A ball  valve  device  for  controlling  fluid  flow has  a stainless steel ball positioned in the lumen of an I.V. tube.          The outer diameter of the ball is equal to the inner diameter of  the  I.V.  tube,  so  that  the  outer  surface  of  the  ball establishes a fluid seal with the inner surface of the tube.  A latex sheath surrounds the tube in the proximity of the ball to provide  resilience  and  memory  for  the  tube.    Inserts  are positioned in the lumen both upstream and downstream from the ball  to hold  the ball  in position under the sheath.   Each insert is formed with a lumen for fluid flow, and has a tapered surface adjacent  to the  ball,  which prevents the ball from forming a seal with the insert.
