Abstract

An infusion pump for transferring fluid through tubing of an administration set connected to the pump, where the pump includes a housing and a pumping mechanism mounted to the housing. The pumping mechanism includes a plurality of pumping fingers, a motor for sequentially, reciprocally moving the plurality of pumping fingers, and an occlusion sensor configured to detect reverse loading of the tubing to the pumping mechanism. In operation, the occlusion sensor causes at least one of a triggering of an alarm and prevention of the operation of the pumping mechanism when the sensor detects that the administration set tubing is reverse loaded to the pumping mechanism.

Claims

1. An infusion pump for transferring fluid through tubing of an administration set connected to the pump, the pump comprising:

a housing; and

a pumping mechanism mounted to said housing, said pumping mechanism including a plurality of pumping fingers, a motor for sequentially, reciprocally moving said plurality of pumping fingers, and an occlusion sensor configured to detect reverse loading of the tubing to the pumping mechanism,

wherein said occlusion sensor causes at least one of a triggering of an alarm and prevention of the operation of said pumping mechanism when said sensor does not detect the tubing mounted on the pumping mechanism.

2. The pump of claim 1, further comprising a misload sensor configured to detect the tubing when the tubing is properly loaded on the pumping mechanism.

3. The pump of claim 2, further comprising a valve associated with one of said pumping fingers and configured to occlude the tubing.

4. The pump of claim 1, further comprising a valve associated with said pumping finger positioned at an end of said pumping mechanism and configured to occlude the tubing.

5. The pump of claim 1, wherein said alarm includes one of an audio indicator, a visual indicator or a tactile indicator.

6. The pump of claim 1, further comprising an input, wherein operation of the pumping mechanism is initiated when said occlusion sensor detects normal loading of the tubing on the pumping mechanism.
