Abstract: This disclosure describes a drug delivery device with communication functionality for purposes of transferring information to a user device, such as a smartphone, while maintaining power-efficient operation. The drug delivery device comprises a controller configured to, while operating in the active mode, use one or more sensors to detect that the injection mechanism has performed an injection. The controller is also configured to generate in memory a data entry indicative of the injection and/or a state of the drug delivery device, and switch into the low-power mode subsequent to or contemporaneous with detecting that the injection mechanism has performed the injection. The drug delivery device also comprises a wireless communication module powered by the power source and configured to establish a wireless connection with and transfer a message to a user device while the controller is operating in the low-power mode.

Abstract: A medical device with limited computational capability includes medical hardware, a first register to store a static, substantially unique identifier of the medical device, a second register to store a static encryption key, an interface to receive and transmit data over a short-range communication link, and processing hardware. The processing hardware is configured to apply the static encryption key to the identifier of the medical device to generate an encrypted identifier, transmit the encrypted identifier of to another device via the interface, receive an encrypted identifier of the other device, decrypt the encrypted identifier of the other device using the static encryption key to determine an identifier of the other device, generate a dynamic encryption key using the identifier of the medical device and the identifier of the other device, and apply the dynamic encryption key to medical data transmitted between the medical device and the other device.
