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.

First claim

What is claimed is:

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, and
an 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.

2. The pump of claim 1 , further comprising a misload sensor configured to detect when the tubing is loaded into channels associated with the pumping mechanism.

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

4. An infusion pump for transferring fluid through tubing of an administration set connected to the pump, the pump consisting of:
a housing including a processor; and
a pumping mechanism mounted to said housing, said pumping mechanism including a plurality of independently movable pumping fingers, a motor for sequentially, reciprocally moving said plurality of pumping fingers, and an occlusion sensor mounted to said housing and associated with said pumping mechanism, said processor being in communication with said motor, one of said plurality of independently movable pumping fingers 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,
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.
