PATTERN RECOGNITION SYSTEM AND METHOD FOR THE DETECTION OF STUCK FLUID DROPLETS IN A FLUID DELIVERY LINE OF AN INFUSION SYSTEM
First Claim
1. An infusion system comprising:
- a pump;
a fluid delivery line connected to the pump for delivering fluid;
at least one sensor connected to the fluid delivery line for emitting and receiving signals to detect whether there is air in the fluid delivery line;
a processor in electronic communication with the pump and the at least one sensor; and
a memory in electronic communication with the processor, wherein the memory comprises programming code for execution by the processor, and the programming code is configured to analyze the signals to determine if a stuck fluid droplet is stuck within the fluid delivery line at a location of the at least one sensor.

Abstract
An infusion system includes a pump, a fluid delivery line, a sensor, a processor, and a memory. The fluid delivery line is connected to the pump for delivering fluid. The sensor is connected to the fluid delivery line for emitting and receiving signals to detect whether there is air in the fluid delivery line. The processor is in electronic communication with the pump and the sensor. The memory is in electronic communication with the processor. The memory includes programming code for execution by the processor. The programming code is configured to analyze the signals to determine if a stuck fluid droplet is stuck within the fluid delivery line at a location of the sensor.

17. A method for detecting a stuck fluid droplet in a fluid delivery line of an infusion system comprising the steps of:
-
pumping fluid through the fluid delivery line over at least one sensor; emitting and receiving signals from the at least one sensor into and from the fluid delivery line; and processing measurements of the signals, using a processor, to determine whether a stuck fluid droplet is stuck within the fluid delivery line at a location of the at least one sensor. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32)

33. A method for detecting air in a fluid delivery line of an infusion system comprising the steps of:
-
pumping fluid through the fluid delivery line over at least one sensor; emitting and receiving signals from the at least one sensor into and from the fluid delivery line; and processing measurements of the signals, using a processor, to determine whether the air is in the fluid delivery line by determining a pattern relationship over time of the signals while the signals are below an air/liquid threshold ADC value boundary. - View Dependent Claims (34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47)
