A method for determining a volume of fluid dispensed into a test housing includes creating an electrical potential across at least one input electrode of a plurality of input electrodes and at least one output electrode of a plurality of output electrodes. The input electrodes and the output electrodes are each coupled to the test housing. The method includes receiving at least one signal from the at least one output electrode based on the fluid dispensed into the test housing. The method includes calculating the volume of fluid dispensed into the test housing based on the at least one signal received from the at least one output electrode, a dimension associated with an internal channel defined within the test housing, and a distance between two input electrodes of the plurality of input electrodes.

Measurement of fluid delivery

A test system for measuring a volume of fluid dispensed by a fluid infusion device includes a test housing. The test housing includes an inlet and an internal channel. The inlet is to be coupled to the fluid infusion device to receive the volume of fluid, and the internal channel is in fluid communication with the inlet. The test system includes an input electrode coupled to the internal channel to be in fluid communication with the volume of fluid, and an output electrode coupled to the internal channel to be in fluid communication with the volume of fluid. The test system includes a power source configured to create a voltage potential between the input electrode and the output electrode. The volume of fluid in the internal channel conducts current between the input electrode and the output electrode to facilitate measurement of the volume of fluid dispensed.

Systems and methods for measurement of fluid delivery

A medication pump test device and method of use including a test device for use with a medication pump and a depth indicator, the test device including: an external body portion defining a depth indicator recess operable to receive the fixed portion of the depth indicator; an internal body portion attached to the external body portion, the internal body portion defining a slide spindle passage operable to allow free axial movement of the slide spindle of the depth indicator. The test device maintains the fixed portion of the depth indicator at a fixed axial position along the central axis relative to the medication pump when the fixed portion of the depth indicator is seated in the depth indicator recess, the external contact portion contacts the medication pump, and the internal body portion is seated in the open end of the reservoir compartment.
