ABSTRACT:
A tubing occluder pump is provided that includes a structure for occluding flexible tubing that distributes a relatively low amount of force at the transverse center portion of the tubing during occlusion and a relatively large force at the distal transverse ends of the occluded tubing, utilizing a mechanical advantage. The occluding structure includes a recessed first occluding surface and a projecting occluding surface. The tubing occluding surface is configured so that one-half of a transverse section of occluded tubing generally conforms to its original shape and so that most of the strain energy stored within the occluded tubing is utilized to return the other half of the tubing to an open position. The occluding structure may form part of either a peristaltic pump or a linear pump.
