Embodiment Construction

[0070] refer to Figure 1 to Figure 5 , the autoinjector device of the present invention comprises: a tubular outer body 1 (in particular a cylinder), which extends along the axis X and contains most of the device components. The outer body is formed by two coaxially aligned body parts 1a, 1b having different diameters and separated by a step 1c. The end of the removable end cap 2 abuts against the step 1c, said cap 2 covering the front end 3 of the device. As explained later, the vicinity of the other end (rear end) of the device is formed or marked with angularly spaced reference marks, such as the numerals 0, 1, 2, to denote the resting or storage state (0) of the device and the two operating state (1, 2). 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 injecti...

Abstract

A device for automatic injection of doses of pharmaceutical compounds comprising a sliding cannula (30). When its front end (3) is pressed against the injection site, said sliding sleeve (30) interacts with cam means (26, 27, 28) to activate the actuation of the piston (8), controlling the delivery of the drug dose. Piston guide means (44) are provided for controlling the starting sequence and device preparation means (4) in the dose delivery state. Provides automatic recapping of the needle and resetting of the locked state after each dose is delivered. The reduction in the number of device components leads to a simpler construction and lower costs.

Description

technical field [0001] The present invention relates generally to a device for the injection of medicines, more precisely to an automatic injection of medicines, in particular for allergic emergencies, such as epinephrine, according to the required chronological sequence device of. In particular, the invention relates to a device for two consecutive automatic injections of two doses of a medicament. Background technique [0002] A number of devices of the above-mentioned type are known which allow a patient to self-administer one or more (typically two) doses of a drug. US patent 6575939 discloses an autoinjector device comprising a syringe housed within a housing formed by an inner part and an outer part which can slide relative to each other. By pressing the end of the inner part (needle exit end) against the patient's skin at the injection site, the outer part slides forward along the inner part, thereby unlocking the button. By pressing a button, the syringe and assoc...
