A FINGER-TYPE PERISTALTIC PUMP COMPRISING A RIBBED ANVIL

摘要

The present invention discloses a finer-type peristaltic infusion pump comprising a ribbed anvil. More specifically, a finger-type peristaltic pump, comprising a plurality of pressing-fingers, infusion-tube, and a passive interfacing mechanism is disclosed. The passive interfacing mechanism comprises of means for accommodating said flexible infusion tube and mounting the tube in a location suitable for the pressing-fingers to apply an approximated perpendicular force on said tube to squeeze it; a ribbed anvil rigidly supporting the tube on opposite side to the pressing fingers when it is pressed by said finger; said anvil comprising a plurality of ribs selected from one or more ribs of a group including a plurality of ribs oriented to face said fingers' tip, a plurality of ribs located in between said fingers, or any combination thereof.
