Fluid transporting device of the peristaltic type with a push pin and push plate arrangement

Abstract

A fluid transporting device includes an elastic tube, a tube frame that holds the elastic tube in an arc, a rotary push plate arranged in the arc for facilitating fluid flow inside the elastic tube, and a plurality of push pins disposed between the elastic tube and the center of the arc. Each push pin includes a semispherical end portion that contacts the rotary push plate, a pushing end portion that places a bias on the elastic tube, and adjacent end portions of at least two push pins close the elastic tube when the semispherical end portions are pushed by an outer circumference arc of the rotary push plate.

1 . A fluid transporting device, comprising:
 a tube; and   at least two push pins disposed in the vicinity of the tube;   wherein one end portion of the push pin is bigger than other end of the push pin, and the one end portion of the push pin deforms the tube.   
     
     
         2 . The fluid transporting device as set forth in  claim 2 , wherein the other end portion of the push pin is pushed by a rotary push plate.
