Injecting apparatus comprises means to hold the apparatus against a living body, and a medical liquid in a reservoir of the apparatus is pumped by a pump means which is driven by movement of some portion of the living body, so as to be injected into the living body. The medical liquid may be injected little by little, in which case each cycle of the pump means is effected by a plurality of movements of the living body. The reservoir is made of resilient material, for example, silicone rubber. A modified reservoir comprises an inner bag and an outer bag, with an intermediate space therebetween, which may be filled with a physiological solution of sodium chloride.
