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

摘要

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:
an elastic tube; a tube frame that holds the elastic tube in an arc; a plurality of push pins disposed on one side of the elastic tube; and a rotary push plate arranged for facilitating fluid flow inside the elastic tube from an inlet to an outlet by pushing the plurality of push pins sequentially, the rotary push plate including; a plurality of protrusions that place a bias on the elastic tube by pushing the plurality of push pins sequentially; and a recess disposed between the plurality of protrusions that releases the bias from the elastic tube, wherein the push pins each include:
a rounded shaped end portion that contacts the rotary push plate; anda pushing end portion that places the bias on the elastic tube; and each of the protrusions includes an arc that merges into a first slope that terminates at an outer circumference arc that contacts the rounded shaped end portion of the push pin, and a second slope that extends away from the outer circumference arc.
