Embodiment Construction

[0042] refer to Figure 1 to Figure 5 , the autoinjector device of the present invention comprises: a tubular (especially cylindrical) outer body 1 extending along the axis X and containing most of the device components therein. The front end of the outer body 1 is closed by a removable cover 2, while its rear end, enlarged by the flange 1a, has a protruding collar 3 showing angularly spaced reference marks (specifically the numbers 0, 1 , 2), as explained later, are used to represent the quiescent state (0) and the two operational states (1, 2) of the device. In this specification, the terms "front", "rear" and equivalents refer to parts of the device for needle exit, respectively axially opposite parts. It should also be noted that throughout this specification reference is always made to a device for the automatic injection of two doses of a medicament, but it should be understood that the invention also includes devices capable of delivering at least two doses of a medica...

Abstract

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.
