摘要：
Disclosed is an auto-injector for administering a medicament, comprising: a housing； a cartridge receiver configured to receive a cartridge comprising a first stopper； a drive module coupled to move a plunger rod configured to move the first stopper； a resistance sensor configured to provide a resistance signal indicative of resistance against movement of the plunger rod； and a processing unit coupled to the drive module and to the resistance sensor. The processing unit being configured to: control the drive module to move the plunger rod towards the extended plunger rod position； determine present plunger rod position； receive the resistance signal； determine a cartridge parameter based on the resistance signal and the present plunger rod position； and control the drive module to adjust the movement of the plunger rod based on the cartridge parameter.
