摘要： A pharmaceutical injection device may comprise a main body case having a cartridge holder, a piston that pushes out the pharmaceutical of a pharmaceutical cartridge held in the cartridge holder, a light emitting component, a light receiving component, and a controller. The light emitting component may shine light of different colors on the pharmaceutical cartridge disposed in the cartridge holder. The light receiving component receives light that has been shined from the light emitting component onto the pharmaceutical cartridge and reflected by the pharmaceutical cartridge. The controller may shine from the light emitting component and identify the type of pharmaceutical cartridge.

摘要： A pharmaceutical injection device includes a main body case, a cartridge holder, a latching receiver, a driver, and a manipulation component. The cartridge holder has a holding space and a holder latching component. The holding space is capable of holding a pharmaceutical cartridge. The latching receiver is configured to latch or release the holder latching component according to whether the cartridge holder is closed or open. The driver is configured to automatically release a latching of the latching receiver and the holder latching component. The manipulation component is configured to manually release the latching of the latching receiver and the holder latching component by moving the latching receiver upon being subjected to external pressure. The driver or the manipulation component is configured to release the latching between the latching receiver and the holder latching component.
