Embodiment Construction

[0170] For example figure 1 The shown drug delivery device 1 is implemented as a pen injector. The drug delivery device 1 is a handheld drug delivery device. It comprises a housing 4 comprising various components. Such as Figure 5 As shown, the housing 4 actually comprises or comprises the cartridge holder 30 and the body 20 . Both the cartridge holder 30 and the main body 20 are generally tubular. As shown in the various figures, the proximal end of the cartridge holder 30 is connectable to the distal end of the main body 20 . The cartridge holder 30 includes a window 31 in the side wall to allow visual inspection of the cartridge 10 assembled therein.

[0171] Cartridge holder 30 includes a threaded socket 32 ​​at its distal end. The cartridge holder 30 further comprises a through-opening 33 on its distal surface through which the proximally extending tip of the double-pointed injection needle extends to pierce the distal seal 13 of the cartridge 10 . Figure 5 In , ...

Abstract

In one aspect the present invention relates to a sensor for measuring at least one physical or chemical parameter of a cartridge (10) or syringe filled with a liquid substance. In further aspects theinvention relates to a cartridge (10) equipped with such a sensor as well as to a drug delivery device (1, 2, 3) equipped with such a cartridge (10), wherein the sensor comprises: a planar flexible foil (101) arrangeable to an outer circumference of a barrel (11) of the cartridge (10) or syringe, at least a first and a second measuring electrode (102, 104) arranged on said foil (101), and at leasta first and a second contact electrode (106, 108) arranged on said foil (101), a processor (110) connected to the first and to the second measurement electrodes (102, 104), a transceiver (120) arranged on said foil (101) and connected to the processor (110), wherein the first contact electrode (106) and the second contact electrode (108) are connected to the processor (110).

Description

technical field [0001] The invention relates to the field of measuring at least one physical or chemical parameter of a cartridge filled with a liquid substance, usually a drug. Furthermore, the invention relates to a cartridge provided with such a sensor. In another aspect, the invention relates to a drug delivery device, in particular an injection device for setting and dispensing a dose of a liquid drug. Background technique [0002] Drug delivery devices for setting and dispensing one or more doses of liquid drugs are well known in the art. In general, such devices have a substantially similar function to ordinary syringes. [0003] Drug delivery devices like pen injectors must meet some user-specific requirements. For example, a patient with a chronic disease such as diabetes may be debilitated and may have impaired vision. Therefore, a suitable drug delivery device especially intended for home use needs to be structurally robust and should be easy to use. Furtherm...
