A base station 240 resets the actuator mechanism in an injection device from its actuated state to its unactuated state so that further actuation of the actuator mechanism can take place. Before further use of the device, the used needle assembly is replaced by a new needle assembly 220. Preferably, the needle assembly is driven by a motor (216, figure 7) powered by a rechargeable battery (218, figure 7), but a drive spring (130, figure 2a) may be used. The base station typically includes a charger (248, figure 7) to replenish the battery. Upon connection to the base station, a controller (217, figure 7) in the injection device operates the motor in reverse to reset the actuator mechanism. A trigger (102, figure 1a) is also reset. |
