Embodiment Construction

[0048] figure 1 and 2 A perspective view of a needle guard is shown, which can be slipped onto the distal end of the injection device. The injection device is preferably an injection device which allows adjustment of the dose of an injectable product, such as insulin, and repeated delivery of the adjusted dose. Preferably, the dose can also be readjusted for each injection. The injection device is preferably of the type such as an injection pen commonly used in the self-administration of medicines, for example in the treatment of diabetes. The injection device is thus designed for multiple injections, preferably for longer periods of use. In contrast, the needle guard comprising the injection needle 1 for the injection device is intended for only one single injection, that is to say only for single use. The needle guard is fastened for use, for example screwed on or, as in the exemplary embodiment, fitted over the distal end of the injection device and is removed after inj...

Abstract

The invention relates to a needle protection device for, or arranged on, an injection appliance, the device comprising a needle protection element (6) which moves into a blocking engagement position as a result of the elastic force, when it (6) moves from the starting position into at least a triggering position, over a small part of the release course (X), and is no longer subjected to the outer force in the triggering position (Y).

Description

technical field [0001] The invention relates to a needle guard fixed or capable of being fixed on an injection device. The needle guard is preferably used in administration operations such as the self-administration of drugs, such as insulin, and can be used in particular in self-administration operations, ie the drug is administered by the patient himself. The injection device may be a simple syringe or a syringe that is disposed of as waste after a single use. In such an application, the needle guard can either be produced separately from the injection device and be connected to it for the given operation, or can be an likewise integrated component of the injection device and be discarded together with the injection device clean up. Preferably, however, the injection device is an injection device for repeated use, and especially preferably an injection device that allows adjustment of the dose of the product to be administered. The injection device may in particular be an...
