Abstract: A drug delivery device includes a housing defining a shell, a drug delivery assembly at least partially disposed within the housing, a cap defining an opening and being adapted to at least partially cover an end of the housing, at least one electronic component, a power source which powers the at least one electronic component, and a switch assembly. The drug delivery assembly comprises a guard which engages an inner surface of the housing and is movable between a first position, a second position, and a third position relative to the housing and is adapted to restrict external contact with a cannula. The switch assembly causes the power source to provide power to the at least one electronic component when the cap is removed from the housing, restrict the power source from providing power when the cap is coupled to the housing and the guard is in the first position, and cause the power source to provide power when the cap is coupled to the housing and the guard is in the third position.

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.

Abstract: A drug delivery device includes a housing, a drug delivery assembly disposed within the housing along a longitudinal axis, and a cap defining a shell. At least one electronic component, a power source, and a switch assembly are at least partially disposed in and coupled to the cap. The switch assembly is movable along a plane orthogonal to the longitudinal axis of the drug delivery assembly to cause the power source to provide power to the electronic component. The device further includes an activation mechanism at least partially disposed in the cap. Upon urging the cap along the longitudinal axis in a direction away from the housing, the activation mechanism engages the switch assembly and causes the switch assembly to move, thereby causing the power source to provide power to the at least one electronic component.
