Embodiment Construction

[0151] figure 1 A drug delivery device in the form of an injection pen is shown. The device has a remote ( figure 1 the left end of the center) and the proximal end ( figure 1 the right end of the middle). exist figure 2 The components of the drug delivery device are shown in . The drug delivery device comprises a body or housing 10, a cartridge holder 20, a lead screw (piston rod) 30, a drive sleeve 40, a nut 50, a dose indicator (number sleeve) 60, a trigger element in the form of a button 70 , dial handle or dose selector 80, torsion spring 90, cartridge 100, metering element 110, clutch plate 120, clutch spring 121 and support 140. The needle combination with hub and shield can be provided as an add-on assembly, which can be replaced as explained above. All components revolve around image 3 The common main axis I of the shown mechanisms is located concentrically. In addition, the monitoring device 130 ( Figure 1 to Figure 3 not shown in) may be attached to butt...

Abstract

The present invention generally relates to a drug delivery device for selecting and dispensing a plurality of user variable doses of medicaments. The device comprises a housing (10) and at least two separate constituent parts (40; 60), wherein, for example, at least one of these constituent parts (60) moves relative to the housing (10) during dose setting, e.g. At least one of the constituent parts (40; 60) moves relative to the housing (10) during dose dispensing, the at least two independent constituent parts (40; 60) differ in relative movement relative to each other during dose setting for relative movement with respect to each other during dose dispensing. The device also includes a monitoring device (130), wherein at least one component (70; 120) of the device is light-transmissive to allow the monitoring device (130) to monitor the dose of at least two separate components (40; 60). Movements during setting and / or during dose dispensing are optically detected relative to the device (10), relative to the monitoring device (130) and / or relative to each other.

Description

technical field [0001] The present invention generally relates to a drug delivery device for selecting and dispensing a plurality of user variable doses of medicaments. The device comprises a housing and at least two separate components, wherein during dose setting, at least one of these components moves relative to the housing or another component (eg, a button), and during dose dispensing, these components At least one of the constituent parts moves relative to the housing, and wherein the relative movement of the at least two independent components relative to each other during dose setting is different from that of the at least two independent constituent parts relative to each other during dose dispensing relative movement. Background technique [0002] Pen-type drug delivery devices are used in situations where regular injections are administered by persons without formal medical training. This may be increasingly common among patients with diabetes, and self-treatme...
