STATUS SENSING SYSTEM IN AN INJECTION DEVICE ASSEMBLY

An injection device assembly is described that includes a housing, a syringe, a drive mechanism, and one or more sensing systems. The drive mechanism advances the syringe from the storage position to the injection position and the plunger advances the syringe piston from the initial position to the final position. The status sensing system may include one or more primary PCBs disposed in an end portion of the injection device assembly housing. The system may determine various parameters related to the operational status of the injection device, including the location of components of the device, the amount of drug remaining in the device, the temperature of the drug, and whether the device is properly contacted with the user's skin prior to injection. The system may communicate such determined parameters to an external device via a wireless communication link. 描述了一种注射设备组件，其包括壳体、注射器、驱动机构和一个或多个感测系统。驱动机构将注射器从存储位置推进到注射位置，并且柱塞将注射器活塞从初始位置推进到最终位置。状态感测系统可以包括布置在注射设备组件壳体的端部部分中的一个或多个主PCB。该系统可以确定与注射设备的操作状态有关的各种参数，包括该设备部件
