Flow stop insert apparatus and methods
First Claim
1. A pressure plate for attachment to an infusion pump, comprising:
- a tubing support surface at least partially surrounded by a raised perimeter support comprising a raised rail and a plurality of raised supporting structures;
a plurality of guide structures extending from the raised perimeter support that define a passageway for an infusion pump tube; and
an attachable flow stop assembly, including;
an attachable occlusion arch including a plurality of tab structures that attachably couple to the raised perimeter support, the occlusion arch further including an aperture configured to surround an infusion pump tube threaded therethrough; and
an attachable flow stop arm operatively coupled to the raised perimeter support adjacent the attachable occlusion arch in a spring-biased fashion such that the aperture in the occlusion arch may be selectively occluded by the flow stop arm.

Abstract
An embodiment is directed to pressure plate for attachment to an infusion pump, where the pressure plate includes a tubing support surface at least partially surrounded by a raised perimeter support. The pressure plate includes a plurality of guide structures extending from the raised perimeter support that define a passageway for an infusion pump tube. Additionally an attachable flow stop assembly is included that includes an attachable occlusion arch and an attachable flow stop arm. The attachable occlusion arch includes a plurality of tab structures that couple to the raised perimeter support. The occlusion arch further includes an aperture configured to surround an infusion pump tube threaded therethrough. The attachable flow stop arm is operatively coupled to the raised perimeter support adjacent the attachable occlusion arch in a spring-biased fashion such that the aperture in the occlusion arch may be selectively occluded by the flow stop arm.

8. A cassette reservoir attachment of an infusion pump, comprising:
-
a reservoir housing for enclosing a quantity of fluid; an infusion tube to supply the fluid from the reservoir housing; a pressure plate including; a tubing support surface for supporting a section of the infusion tube extending from the reservoir housing; a plurality of retention and guide features formed in the tubing support surface; a free flow protection device that prevents free-flow of fluid in the tube, including; an attachable occlusion arch with snaps that attach to retention and guide features; and an attachable flow stop arm operatively coupled to the retention and guide features for movement adjacent the attachable occlusion arch to selectively occlude an infusion tube passing through the occlusion arch. - View Dependent Claims (9)

10. An attachable flow stop assembly for use in occluding a tube of an infusion pump, comprising:
-
an attachable occlusion arch including tab structures to attachably couple to a pressure plate of an infusion pump, the occlusion arch defining a passageway to at least partially surround a length of an infusion pump tube; and an attachable flow stop arm operatively coupled to the pressure plate for movement adjacent the attachable occlusion arch in a spring biased fashion to selectively occlude the passageway defined by the occlusion arch. - View Dependent Claims (11, 12, 13, 14)
