Embodiment Construction

[0130] Such as figure 1 and figure 2 The illustrated injection device 1 is a prefilled disposable injection device comprising a housing 10 to which an injection needle 15 can be secured. The injection needle 15 is protected by an inner needle cap 16 and an outer needle cap 17 or a protective cap 18 configured to surround and protect the distal section of the housing 10 of the injection device 1 . Housing 10 may include and form a main housing portion configured to house, for example, figure 2 The drive mechanism 8 is shown. The injection device 1 may further comprise a distal housing part denoted cartridge holder 14 . The cartridge holder 14 may be permanently or releasably connected to the main housing 10 . The cartridge holder 14 is typically configured to accommodate a cartridge 6 filled with a liquid medicament. The cartridge 6 comprises a cylindrical or tubular barrel 25 which is sealed in the proximal direction 3 by a bung 7 located inside the barrel 25 . The bun...

Abstract

The present disclosure relates to a rotation sensor for an injection device (1), the rotation sensor comprising: a rotatable element (201) configured for a mechanical engagement with a ratchet mechanism (90; 190), the rotatable element (201) comprising an outer rim (208) and a hub (210) is configured for transmission of a torque between the outer rim (208) and the hub (210), at least one sensor (220, 222, 224) attached to the rotatable element (201) and configured to measure at least one of a mechanical force, a mechanical pressure or a mechanical strain at a portion of the rotatable element (201) during a rotation of the rotatable element (201), a processor (112) connected to the at least one sensor (220, 222, 224) and configured to calculate an angle of rotation of the rotatable elementon the basis of a sensor output of the at least one sensor (220, 222, 224).

Description
