The peristaltic pump, which is primarily used in the medical field in dialysis and heart/lung bypass devices, eliminates the need for aspirated materials to pass through a motorized mechanism or impellor. The aspirator creates a vacuum by compressing flexible tubing, using a series of three rollers which rotate in a housing at a high rate of speed. This allows the isolation of the aspirated material from any moving part of the mechanism, thus eliminating the possibility of contamination or clotting, a common problem with all other electric aspirating devices.
