Abstract

The present invention relates to a reusable drug delivery device (1) for selecting and dispensing a plurality of user variable doses of drugs. The device (1) comprises a housing (10, 20), a cartridge holder (80) for holding a cartridge (81) containing a drug, a piston rod displaceable relative to the cartridge holder (80) ( 30), a driver (40) coupled to the piston rod (30), a display member (60) for indicating the set dose and coupled to the housing (10, 20) and the driver (40), and a display member (60) coupled to the display member (60) ) and the button (70) of the driver (40).

Description

technical field [0001] The present invention generally relates to drug delivery devices. More specifically, the present invention relates to reusable drug delivery devices. Background technique [0002] Pen-type drug delivery devices may be used by persons without formal medical training for routine injections. This application may be increasingly common in patients with diabetes, where self-treatment allows such patients to effectively manage their disease. Indeed, such drug delivery devices allow the user to self-select and dispense multiple user-variable doses of drug. The present invention does not relate to so-called fixed dose devices which only allow to dispense a predetermined dose without the possibility to increase or decrease the set dose. [0003] There are basically two types of drug delivery devices: resettable devices (ie, reusable devices) and non-resettable devices (ie, disposable devices). For example, disposable pen delivery devices are supplied as sel...
