A device for the automatic injection of doses of a drug is described. The device has a slide and cam means, a syringe unit with a piston, and guide means. The axial movement of the slide initiated by a user by depressing its front end against an injection site, causes an angular displacement of the cam means that, in cooperation with the guide means, controls movement of the syringe piston and therefore administration of a drug dose. |
