An apparatus method, and system for detecting a leaking occluder valve is disclosed. At least one measurement instrument is connected to a fluid within a fluid tubing upstream or downstream of a pump element of an infusion device. The pump element is configured to periodically cause a compression of the fluid tubing and to isolate a downstream portion of the fluid tubing from an upstream portion of the fluid tubing when the pump element is operating under a normal operating condition. A response of the fluid is measured when the pump element is caused to compress the fluid tubing and a determination is made, based on the response whether the compression has fluidically isolated the downstream portion from the upstream portion. One or more shims may be inserted into the occluder valve to move the platen away from the pump element during the test to determine a degree of fault.

An infusion pump for detection of a fluid condition in a flexible tubing is provided. The infusion pump includes a sensor positioned to obtain a value of a tubing force when the tube is received by the infusion pump, a memory storing instructions and a processor. The processor is configured to execute the instructions to generate a force-time curve representative of values of the tubing force obtained by the sensor over time, determine a time-decaying parameter associated with the tubing force characterizing the force-time curve, and determine a fluid pressure value for a fluid in the tube based at least in part on the time-decaying parameter, a material of the tube, a dimension of the tube, and a use history of the tube. A method for using an infusion pump is also provided.

A programmer device includes an interface that communicates with an implantable fluid delivery device and a user interface that allows a user to troubleshoot a catheter connected to the fluid delivery device by measuring a pressure associated with the catheter. A processor may compare the measured pressure waveform to a previously-acquired waveform or the user interface may display the measured pressure waveform for the user to compare the displayed pressure waveform to a previously-acquired baseline waveform. The comparison between the two waveforms may be based on the pressure decay time. A historical log of measured pressure decays associated with the catheter may be maintained by the programmer device or the implantable fluid delivery device and displayed for the user to determine whether the performance of the catheter is deteriorating.
