Apparatus and method for preventing free flow in an infusion line
First Claim
Patent Images
1. A method for controlling free flow in an infusion set mounted in an infusion pump, the method comprising:
- selecting an infusion set having a proximal piece of tubing, a distal piece of tubing and a connector connecting the piece of tubing, the connector having an occluder attached thereto; and
engaging the tubing of the infusion set with a pumping mechanism of the pump so that the connector is disposed downstream from the pumping mechanism; and
pressing against one side of the tubing adjacent the occluder without pressing against an opposing side of the tubing to thereby allow flow past the occluder.

Abstract
An apparatus and method for preventing free flow through an infusion set utilizes an occluder disposed within the infusion set to selectively prevent flow therethrough. The occluder may be responsive to a pressure differential within the infusion set or may respond to compression of the infusion set. When a pair of occluders are used in sequence, an in-line pump may be formed.

4. A method for selectively controlling free flow through an infusion set, the method comprising:
-
forming an infusion set having tubing and an occluding mechanism disposed in the tubing which occludes fluid flow through the tubing in an ambient state; and applying pressure to a single side the tubing to enable flow to pass the occluder and thereby enable fluid flow through the tubing. - View Dependent Claims (5, 6, 7, 8, 9, 10)

11. A method for controlling flow of solution through an tube, the method comprising;
-
selecting flexible a tube; disposing an occluder in the tube; and compressing one side of the tube adjacent the occluder to open a flow channel between the occluder and an opposing side of the tube. - View Dependent Claims (12)

13. A method for selectively controlling free flow in an infusion set, the method comprising:
-
selecting an infusion set having a proximal and a distal end; and disposing a free standing occluder between the proximal end and distal end of the infusion set such that it selectively prevents flow through the infusion set, the occluder being unattached to an anchor. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27)
