Infusion pump including reverse loading protection
First Claim
1. An infusion pump for transferring fluid through tubing of an administration set connected to the pump, the pump comprising:
- a housing including a processor;
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;
a valve mounted to said housing and associated with one of said plurality of pumping fingers, said valve being in communication with said processor and configured to occlude the tubing at a point adjacent to said one of said plurality of pumping fingers, andan occlusion sensor mounted to said housing and associated with one of said plurality of pumping fingers, said processor being in communication with said motor, said valve, and said occlusion sensor and being configured to detect a blockage in an upstream portion of the tubing, which is upstream of the plurality of pumping fingers on a first side of the pumping mechanism wherein the tubing extends from a fluid container to the pumping mechanism, or a downstream portion of the tubing, which is downstream of the plurality of pumping fingers on a second side of the pumping mechanism wherein the tubing extends from the pumping mechanism to a patient, wherein reverse loading of the tubing to the pumping mechanism causes a blockage in the upstream portion of the tubing; and
wherein said processor causes at least one of a triggering of an alarm and prevention of the operation of said pumping mechanism when said occlusion sensor detects a blockage in the upstream portion of the tubing mounted on the pumping mechanism.

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.
