Abstract

The invention relates to an injection device (1) for the simultaneous administration of several medications. The injection device (1) comprises a carrying housing (5), an activation sleeve (8) surrounding the carrying housing (5), at least two carpules (9, 11), a first drive module (13) for the administration of the medications, a securing device (14), a needle arrangement (17), a needle protection element (20), and a second triggerable drive module (21) for the needle arrangement (17). The carpules (9, 11) are arranged next to another. The first drive module (13) comprises a drive element (22) with a number of piston rods (23, 24) equal to the number of carpules (9, 11), which form a composite structural unit. At least one of the piston rods (23, 24) is configured in the form of a hollowcylinder and is formed as closed on the piston side, wherein arranged inside this is a first drive means (26) of the first drive module (13).

Description

technical field [0001] The present invention relates to an injection device, in particular an autoinjector, for the simultaneous administration of at least two medicaments. Background technique [0002] An injection device of general construction is known from WO 2009 / 152542 A1, which has a distal part and a proximal part. The injection device can be automatically moved from the stored setting to the injection position. The device comprises a bearing housing configured as a sleeve, designed to be subdivided into a front bearing housing part and a rear bearing housing part, and comprising a distal end and a proximal end. The carrier housing is surrounded over most of its length by the actuation sleeve, wherein the distal end of the carrier housing protrudes beyond the actuation sleeve. In order to trigger the injection device, the actuation sleeve is movable in axial direction relative to the carrier housing. Mounted in the carrier housing are the ampoule and needle set. ...
