Abstract
An apparatus as disclosed for the venting of gases contained in fluids passing through a primary conduit in connection with medical treatments comprising throttling means interposed in the primary conduit, pump means downstream of the throttling means for drawing the fluid through said primary conduit, means for enhanced bubble formation in the fluid positioned between the throttling means and pump means in the primary conduit, and venting means disposed in the primary conduit downstream of the pump means, the venting means for removing gaseous bubbles from the fluid when the fluid is passed therethrough.
Claims15
An apparatus for the venting of gases contained in the fluid passing through a primary conduit in connection with medical treatments comprising:
- throttling means interposed in said primary conduit;
- pump means downstream of said throttling means for drawing said fluid through said primary conduit;
- means for enhanced bubble formation in said fluid positioned between said throttling means and pump means in said primary conduit;
- a shunt conduit in fluid communication with said means for enhanced bubble formation and said primary conduit;
- and
- venting means disposed in said primary conduit downstream of said pump means, said venting means for removing gaseous bubbles from said fluid when said fluid is passed therethrough.
An apparatus for the venting of gases contained in a fluid passing through a primary conduit in connection with medical treatments comprising:
- throttling means interposed in said primary conduit;
- pump means downstream of said throttling means for drawing said fluid through said primary conduit;
- an expansion chamber having an inlet port and an outlet port, said expansion chamber positioned between said throttling means and pump means in said primary conduit;
- a shunt conduit in fluid communication with said expansion chamber, said shunt conduit connected at a point in said expansion chamber capable of emptying said expansion chamber of said liquid in said primary conduit in cooperation with said pump means;
- and
- venting means disposed in said primary conduit downstream of said pump means, said venting means for removing gaseous bubbles from said fluid when said fluid is passed therethrough.
