Abstract
An ambulatory infusion system and a method of operating including a disposable infusion cartridge having a collapsible reservoir and a substantially rigid shell disposed over the collapsible reservoir having an interior volume, a pump device, a pressure sensor in communication with the interior volume and a processor. The method includes actuating the pressure sensor to take pressure measurements at regular time intervals; periodically assessing a preselected number of the pressure measurements with statistical analysis to identify statistical measures associated with the pressure measurements; and using the statistical measures to assess the status of the flexible reservoir and the pump device.
