摘要 |
A peristaltic pump includes a plurality of rollers for compressing and sealing a collapsible and resilient tube. A housing and a pump arm with a specific arcuate surface and position with respect to the housing enable the succesive contact and gradual compression of the rollers with the tube in a manner for moving a fluid through the tube in one direction without creating substantial fluid back pressure in an opposite direction.
