Problems solved by technology

[0004] The needle covers of such devices, such as those known from DE 197 55 125 A1 and DE 100 09 816 A1, have the disadvantage that the needle cover is not connected to the injection device until the needle holder has been connected to the injection device
The consequence of this is that the user has to attach the needle cover to the injection device with the needle exposed, so it can be said that the user has to work with the exposed needle when the needle cover is attached

Embodiment Construction

[0036] Fig. 1 shows an exploded view of the distal part of an injection device according to the invention, the individually manufactured parts of which are arranged in a sequence suitable for assembly along the central longitudinal axis L of the injection device in Fig. 1 . figure 2 The same parts are shown assembled.

[0037] The distal part of the injection device comprises a container holder 1 and a casing structure 5, e.g. from figure 2 As can be seen in the figure, the cladding structure 5 forms the distal part of the housing of the injection device when assembled. The distal part of the injection device also comprises a needle cover 15 and a return means 14 formed by a coil spring which, when assembled, compresses axially against the container holder 1 and the needle at each axial position of the needle cover 15. Cover between 15. As shown in Figure 1, especially Figure 2-4 As shown, when assembled, the needle cover 15 is accommodated in the distal part of the contai...

Abstract

An injection device comprising a needle cover (15), comprising: a housing (1, 5) forming a receptacle for receiving a container containing an injectable product or forming the container itself; Delivery device; a needle holder (10) comprising an injection needle (11) via which the needle holder (10) is fluidly connected or fluidically connectable to a container. The needle cover (15) is mounted by the housing (1, 5) in such a way that the needle cover (15) can move in the proximal direction against a restoring force, from the protection position through the injection position, moving to the assembly position. In the protected position, the needle cover (15) extends beyond the distal tip of the injection needle (11), while in the injection position, the needle cover (15) is shorter than the needle tip. In said assembled position, the needle cover (15) allows access to the needle holder (10), so that the needle holder (10) can be grasped and connected to the housing (1, 5) and / or removed from the housing ( 1, 5) on and off.

Description

technical field [0001] The present invention relates to an injection device comprising a needle cover for an injection needle which may be or has been attached to the front distal end of the injection device. The injection device is preferably used in the self-administration of injectable products such as insulin, growth hormone or osteoporosis agents. The injection device can especially be an injection pen. Background technique [0002] On the one hand, the needle of the injection device presents a risk of injury, for example when changing the needle, and on the other hand, the needle of the injection device is a source of fear for many patients who self-administer the product by injection ( needle phobia), which can indeed be a cause of incorrect or at least suboptimal injections. In order to reduce the fear of injection needles, injection devices are usually provided with a needle shield surrounding the needle in a protective position, so that the user of such an inject...
