Abstract: A method of pairing a therapeutic product delivery device to a handset is described. The handset is restricted to controlling only delivery devices which it is paired with. The method comprises the steps of: at the delivery device, setting, in response to the delivery device being connected to a charging device, a pairing indicator indicating that the delivery device is available for pairing, and broadcasting the pairing indicator using a radio transceiver; at the handset, discovering the delivery device based on the broadcast pairing indicator; and pairing the discovered delivery device and the handset together. By limiting the handset to pairing with devices which are broadcasting a pairing indicator, and by limiting the setting and/or broadcast of the pairing indicator to when the delivery device is connected to a charging device, the risk of accidentally pairing the wrong delivery device (for example someone else's) to the handset is greatly reduced.

Abstract: 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).
