Patent ID: 8418364

Claim:
A method for extending useful life of tubing of a high pressure peristaltic pump without removing the tubing, the method comprising: disconnecting an inlet channel extending outside of the pump from a first connector secured to a first end of the tubing of the peristaltic pump and mounted within a first port formed in a pump housing; disconnecting an outlet channel extending outside of the pump from a second connector secured to a second end of the tubing of the peristaltic pump and mounted within a second port formed in a pump housing; connecting the inlet channel to the second end of the tubing of the peristaltic pump and connecting the outlet channel to the first end of the tubing, wherein the connecting of the inlet channel to the second end of the tubing of the peristaltic pump and the connecting of the outlet channel to the first end of the tubing is performed (1) without disconnecting the first connector from the first end of the tubing of the peristaltic pump, (2) without unmounting the first connector from within the first port of the pump housing, (3) without disconnecting the second connector from the first end of the tubing of the peristaltic pump and (4) without unmounting the first connector from within the first port of the pump housing; reversing rotation of a rotor of the peristaltic pump from a first rotational direction to a second rotational direction, the first rotational direction used while the inlet channel is connected to the first end such that rotation of the rotor of the peristaltic pump compresses the tubing along its length from the first end to the second end, the second rotational direction used when the inlet channel is connected to the second end such that rotation of the rotor of the peristaltic pump compresses the tubing along its length from the second end to the first end.
