Peristaltic pump

A peristaltic pump which utilizes a length of elastic tubing in effecting pumping action comprising:

• a frame;
• a pumping chamber on said frame including peristaltic pumping means for progressively squeezing and releasing consecutive portions of an intermediate section of said tubing to pump fluid in said tubing in a predetermined direction;
• and
• tubing feeding means on said frame comprising powered frictional gripping means to engage the outer periphery of said tubing, on sections adjacent to either side of said tubing intermediate section, and feed said tubing through said feeding means and said pumping chamber in said predetermined direction at a controlled rate during pumping of said fluid.

• and
• tubing feeding means on said frame comprising gripping means to engage the outer periphery of said tubing, on at least one section adjacent to said tubing intermediate section, and feed said tubing through said pumping chamber in said predetermined direction at a controlled rate during pumping of said fluid, said tubing feeding means being drivingly connected to said peristaltic pumping means to provide power to said tubing feeding means.
