MULTI-SENSOR INFUSION SYSTEM FOR DETECTING AIR OR AN OCCLUSION IN THE INFUSION SYSTEM
First Claim
1. An infusion system for being operatively connected to a fluid delivery line and to an infusion container containing an infusion fluid, the infusion system comprising:
- a pump;
a plurality of different types of sensors connected to the pump or the fluid delivery line, the plurality of different types of sensors configured to indicate whether air is in the fluid delivery line;
at least one processor in electronic communication with the pump and the plurality of different types of sensors; and
a memory in electronic communication with the at least one processor, wherein the memory comprises programming code for execution by the at least one processor, and the programming code is configured to, based on measurements taken by the plurality of different types of sensors, determine the following;
(1) whether there is air in the fluid delivery line;
(2) whether there is a partial occlusion or a total occlusion in the fluid delivery line;
or (3) a percentage of the air present in the fluid delivery line or the probability of the air being in the fluid delivery line.

Abstract
An infusion system for being operatively connected to a fluid delivery line and to an infusion container includes a pump, a plurality of different types of sensors connected to the pump or the fluid delivery line, at least one processor, and a memory. The plurality of different types of sensors are configured to indicate whether air is in the fluid delivery line. The memory includes programming code for execution by the at least one processor. The programming code is configured to, based on measurements taken by the plurality of different types of sensors, determine: whether there is air in the fluid delivery line; whether there is a partial occlusion or a total occlusion in the fluid delivery line; or a percentage of the air present in the fluid delivery line or the probability of the air being in the fluid delivery line.
