Medication pump test device and method of use
First Claim
1. A test device for use with a medication pump and a depth indicator, the medication pump defining a reservoir compartment having an open end with an open end diameter, the depth indicator having a fixed portion and a slide spindle slideably connected to the fixed portion, the test device comprising:
- an external body portion having an external diameter greater than the open end diameter, the 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 having an external diameter less than the open end diameter and defining a slide spindle passage operable to allow free axial movement of the slide spindle of the depth indicator, a junction of the internal body portion and the external body portion defining an external contact portion;
wherein the depth indicator recess and the slide spindle passage are in communication along a central axis of the test device, andthe 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.

16. A method of testing a medication pump, the medication pump defining a reservoir compartment having an open end and including a pump motor slide disposed in the reservoir compartment, the method comprising:
-
providing a medication pump test system including a depth indicator and a test device affixed to the depth indicator, the depth indicator having a fixed portion and a slide spindle slideably connected to the fixed portion, the depth indicator providing a depth measurement in response to position of the slide spindle, the test device having an external body portion and an internal body portion attached to the external body portion, a junction of the internal body portion and the external body portion defining an external contact portion, the external body portion being attached to the fixed portion of the depth indicator and the internal body portion defining a slide spindle passage operable to allow free axial movement of the slide spindle of the depth indicator; seating the internal body portion of the test device in the open end of the reservoir compartment with the external contact portion of the test device in contact with the medication pump; contacting a face of the pump motor slide with a tip of the slide spindle; recording a first depth measurement from the depth indicator; and subjecting the medication pump to test conditions.
