Patent ID: 7878773

Claim:
A peristaltic pump comprising: a pumphead having a separate suction side and discharge side; a rotor rotatably mounted to the pumphead; a first mounting block adjustably attached to the suction side of the pumphead and a second mounting block attached to the discharge side of the pumphead, each of the first and second mounting blocks having a recess therein for receiving a collar, each of the first and second mounting blocks being free from connection from the other of the first and second mounting blocks, and each of the first and second mounting blocks being moveable independently from the other of the first and second mounting blocks and the pumphead; a flexible tube comprising: a first end having a first collar affixed thereto, the first end secured to the first mounting block attached to the suction side of the pump head with the first collar at least partially located within the recess of the first mounting block; and a first end having a second collar affixed thereto, the second end secured to the second mounting block attached to the discharge side of the pump head with the second collar at least partially located within the recess of the second mounting block; and at least one compliant member positioned between each of the first and second mounting blocks and the suction side and discharge side of the pumphead respectively, thereby enabling the flexible tube and the first and second mounting blocks to move axially independently from one another with respect to the suction side and the discharge side of the pumphead and dynamically transfer tension-induced stress during pumping from the flexible tube to the at least one compliant members positioned between each of the first and second mounting blocks and the suction side of and the discharge side of pumphead respectively.
