Abstract
A drug pump testing system and method comprise a pump control module having tube engaging members, with the pump control module coupled to a calibration cassette. The calibration cassette houses a reservoir bag comprising a fluid chamber and a collection area. The fluid chamber contains a known test volume prior to the initiation of the test cycle. The fluid chamber of the reservoir bag is coupled with a tube leading to the collection area, and the tube is positioned along the calibration cassette for occlusion by the tube engaging members of the pump control module. The reservoir bag comprises a fluid chamber and a collection area. The cassette can be a dual purpose cassette which tests sensors on the pump control module and also tests the accuracy of the pump control module.
