Abstract

Multi-channel IV therapies are achieved through the use of a single source infusion pump, which incorporates three rotary chambers. Each rotary chamber is composed of a base panel with the appropriate cavity for housing a rotor with three sets of rollers, plus tubing defined pathway going into and out of the rotor cavity. Components such as a knob and a sliding latch are incorporated into the inflow and outflow pathways on the base panel respectively to accommodate the installation and removal of anti-free flow disposable IV pump sets. These features also ensures that a properly installed anti-free flow IV pump set will remain secured in the base panel, even when mechanical impulses are experienced by the pump. The chamber tubing of the anti-free flow disposable IV pump set is composed of thin-walled rubber tubing that connects to an inflow stopcock and terminates through outflow clear connector. Fluid within the installed chamber tubing is pushed forward as the rotor rotates and its rollers roll and compress onto the rubber tubing against the wall of the cavity. A force sensor is incorporated in the inflow pathway on the base panel to detect upstream occlusion in the IV pump set, and an air detection system is incorporated in the outflow pathway on the base panel to detect the presence of air within clear connector.

Claims

1. A single unit infusion pump that incorporates three rotary chambers, and each said rotary chamber is composed of a rectangular shaped panel with the appropriate cavity for housing a rotor with circular shaped body and flexible three arms that are spaced 120 degrees apart, and each said arm holds a roller, which as the said rotor rotates by means of a motor driven source, the said rollers exert sufficient compressive force onto the installed chamber tubing of the anti-free flow disposable IV pump set, resulting in fluid being delivered from the IV source to the patient.

2. The pump of claim 1, in addition that the said rectangular shaped panel includes a tubing pathway that dictates the inflow and outflow into the said rotor cavity, whereby the said inflow pathway incorporates a seating/knob and the said outflow pathway incorporates a sliding latch, which accommodates the ease of installation and removal of said anti-free flow disposable IV pump set of claim 1.

3. The anti-free flow disposable IV pump set of claim 1, which the said chamber tubing is composed of thin-walled translucent rubber sized for optimum fluid transport that connects form an inflow stopcock and terminates through an outflow clear connector.

4. The pump of claim 2, in addition that said inflow tubing pathway of the said panel incorporates a force sensor to detect the upstream occlusion effect experienced on the said anti-free flow disposable IV pump set.

5. The pump of claim 4, in addition that said outflow-tubing pathway of the said panel incorporates an air bubble detector system to detect the presence of air within the said clear connector of claim 3.
