摘要： To detect air in a fluid delivery line of an infusion system, infusion fluid is pumped through a fluid delivery line adjacent to at least one sensor. A signal is transmitted and received using the at least one sensor into and from the fluid delivery line. The at least one sensor is operated, using at least one processor, at a modified frequency which is different than a resonant frequency of the at least one sensor to reduce an amplitude of an output of the signal transmitted from the at least one sensor to a level which is lower than a saturation level of the analog-to-digital converter to avoid over-saturating the analog-to-digital converter. The signal received by the at least one sensor is converted from analog to digital using an analog-to-digital converter. The at least one processor determines whether air is in the fluid delivery line based on the converted digital signal.

摘要： 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.

摘要： In one step of a method for infusing an infusion fluid, the infusion fluid is pumped through a fluid delivery line of an infusion system. In another step, measurements are taken with at least one sensor connected to the infusion system. In an additional step, an air determination is determined with at least one processor. The air determination is related to air in the fluid delivery line. The air determination is based on the measurements taken by the at least one sensor. The air determination is further based on: (1) medication information regarding the infusion fluid or infusion information regarding the infusion of the infusion fluid; or (2) multi-channel filtering of the measurements from the at least one sensor or non-linear mapping of the measurements from the at least one sensor; and statistical process control charts applied to the multi-channel filtered measurements or applied to the non-linear mapped measurements.

摘要： A method and system for monitoring and managing a remote infusion regimen where a prescribed infusion regimen is provided and compared to subsequent infusion event data to determine if the data falls within predetermined parameters. If the data does not fall within predetermined parameters a monitoring technician, supportive caregiver, patient or some combination thereof are immediately notified so that corrective action may be taken.

摘要： Various systems and methods for detecting air in a chamber of an infusion system are disclosed. In one embodiment, a determination is made that air is contained in the chamber on the basis of a change in the average force exerted against the plunger utilizing a derivative spike for event detection and a systematic reduction in the average force to confirm the nature of the change. In another embodiment, a determination is made that the chamber contains air when a difference between the current force profile and a baseline force profile crosses a threshold. In an additional embodiment, a force profile is classified as being an air force profile or a liquid force profile based on extracted features of the force profile.
