FINGER-TYPE PERISTALTIC PUMP COMPRISING A RIBBED ANVIL
First Claim
1. A finger-type peristaltic pump (DDS), comprising a plurality of pressing-fingers, infusion-tube, and a passive interfacing mechanism;
- wherein said passive interfacing mechanism comprising (a) a means for accommodating said flexible infusion tube and mounting said tube in a location suitable for said pressing-fingers to apply an approximated perpendicular force on said tube to squeeze it;
(b) a ribbed anvil rigidly supporting said tube on opposite side to said 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 (i) a plurality of ribs oriented to face said fingers'"'"' tip, (ii) a plurality of ribs located in between said fingers, or (iii) any combination thereof.

Abstract
The present invention includes a finger-type peristaltic pump with a ribbed anvil. According to some embodiments, a finger type peristaltic pump may comprise a plurality of pressing fingers, an infusion tube and a passive interfacing mechanism. The passive interfacing mechanism may comprise a channel, groove or other suitable mount for placing and mounting an infusion tube such that the pressing fingers are positioned on one side of the tube and the ribbed anvil on the opposite side. The pressing fingers may be positioned to apply an approximately perpendicular force on the tube, pressing it against the ribbed anvil, thus causing a pumping action.
