摘要：
A therapeutic product delivery device is described which comprises a device body and a cartridge for holding a therapeutic product. An engagement structure is provided for releasably engaging the cartridge with the device body. A fault detector is provided for detecting a fault in the delivery of the therapeutic product from the cartridge. A release trigger is responsive to the detection of a fault to cause the engagement structure to release the cartridge from the device body. In this way, a fault causes the cartridge to be released from the device body, which will prevent any further delivery of the therapeutic product to the patient. This solution is strongly preferable to a solution in which a product delivery mechanism (e.g. a pump) is merely paused or stopped, since when the cartridge separates then no further delivery is possible at all, until the cartridge is reattached (or more probably replaced with a new cartridge in case the fault is with the cartridge).
