POSITIVE GRIP FINGERS IN A PERISTALTIC PUMP
First Claim
Patent Images
1. A method for positive grip peristaltic pumping in a tube type infusion pump, said method comprising:
- providing an adhesion region on a pumping finger of said infusion pump for creating an adhesion between said pumping finger and a pumping segment of said infusion pump; and
such that when said pumping finger is moved from an occluded position to an initial position said adhesion forcibly restores said pumping segment from an occluded state to a non occluded state.

Abstract
A method for enhancing peristaltic pumping in a tube type infusion pump is provided. The method includes providing an adhesion region on a pumping finger of an infusion pump for creating an adhesion between the pumping finger and a pumping segment of the infusion pump such that when the pumping finger is moved from an occluded position to an initial position the adhesion forcibly restores the pumping segment from an occluded state to a non occluded state.

6. A method for positive grip peristaltic pumping in a tube type infusion pump, said method comprising:
-
moving a pumping finger from an initial position to an extended position to occlude a portion of a pumping segment of said infusion pump; removably coupling said pumping finger of said infusion pump to said pumping segment of said infusion pump at said occluded portion of said pumping segment; and such that when said pumping finger is moved from said extended position to said initial position, said coupling forcibly restores said pumping segment to a non occluded state. - View Dependent Claims (7, 8, 9)

11. A positive grip peristaltic pump comprising:
-
a pump comprising a plurality of pumping fingers for pumping fluid in a linear direction through a pumping segment of a line set; an adhesion region on one of said plurality of pumping fingers for creating an adhesion between said pumping finger and said pumping segment; and such that when said pumping finger is moved from an occluded position to an initial position said adhesion forcibly restores said pumping segment from an occluded state to a non occluded state. - View Dependent Claims (12, 13, 14)

15. A line set for use in a peristaltic pump comprising:
-
one or more lines configured for administering fluids to a patient; one or more pumping segments coupled with said lines configured to adhere to an adhesion region on a pumping finger of an infusion pump such that when said pumping finger is moved from an occluded position to an initial position said adhesion forcibly restores said pumping segment from an occluded state to a non occluded state. - View Dependent Claims (16)
