Problems solved by technology

In this case, one housing part houses the trigger means and the other housing part houses the release mechanism, and when the two housing parts are in a first position relative to each other, the release mechanism is farther from the trigger means than when it is in a second position Larger and has no effect on the operation of the trigger device

Embodiment Construction

[0032] figure 1 A first example of an embodiment of an auto-injector is represented. Auto-injectors are designed in the form of injection pens (or injection pens). It comprises a sleeve-shaped proximal housing part 1 acting as a grip and a sleeve-shaped distal housing part 2 . The sleeve-shaped distal housing part 2 forms a needle guard 2a at its distal end. The housing part 2 is axially guided linearly along a common longitudinal axis L within the housing part 1 .

[0033] The housing part 2 houses a reservoir 3 filled with an injectable product, such as insulin. The reservoir 3 is a container and in this example of embodiment a standard ampoule, in which a driver 4 in the form of a plunger is accommodated. The product is dispensed through the outlet of the reservoir 3 and the injection needle 5 connected to the reservoir 3 by axially moving the drive member 4 in the forward drive direction V. An injection needle 5 is attached to the distal end of the reservoir 3 and its...

Abstract

The invention relates to an injection device comprising an elongate housing wherein a container (3) for an active ingredient is arranged. Said housing comprises two housing parts (1, 2) which can be displaced in relation to each other. A drive element (12) can be prestressed by the force of a spring (107) in the direction of injection and can be secured in said position. The release element (20) is displaced from a locked position into an intermediate position due to the displacement of the housing parts (1, 2) in relation to each other when placed on the skin of a patient, wherein the drive element (12) is still locked in an intermediate position. The drive element (12) can be displaced from the intermediate position thereof into a release position wherein the drive element is unlocked by the release element (18) which can be actuated by a button. Said two-step process reliably prevents accidental release.

Description

technical field [0001] The present invention relates to an injection device for administering an injectable product, preferably a liquid drug such as insulin, growth hormone, heparin or an osteoporosis preparation, the injection device preferably being an injection pen or an autoinjector. Background technique [0002] Injection devices of various designs are known which are dedicated to administering medicaments which are administered by the patient himself. Many of the autoinjectors are known with release locks which are used to prevent the injection process from being inadvertently triggered. An example of an automatic injector is disclosed in patent document DE4037418, which has a housing for containing a container of active substance, and which housing consists of two parts movable relative to each other along an axis from a first and a second position , the autoinjector also has a release mechanism, a dispensing mechanism for dispensing the active substance and a trigg...
