Embodiment Construction

[0127] figure 1 is a sectional view of the injection device 1 according to the first embodiment of the present invention. exist figure 1 In , the device 1 is shown in the empty state, ie no dose has been set.

[0128] The injection device 1 comprises a housing 2 , a cartridge accommodating portion 3 with a cartridge 4 disposed therein, and an injection button 5 . At the distal end of the cartridge containing part 3 is attached an injection needle 6 . The piston rod 7 is arranged in contact with a piston 8 arranged inside the cartridge 3 in such a way that moving the piston rod 7 in the distal direction causes the piston 8 to move in the distal direction, thereby allowing the liquid drug to pass through the injection needle 6 Discharge from cartridge 4.

[0129] After the user completes an injection, remove the cap ( figure 1 (not shown in ) is installed at the cap receiving portion 9 on the injection device 1 in such a way as to cover the injection needle 6 . When the ca...

Abstract

A mechanical injection device (1) for injecting apportioned doses of liquid drug. The injection device (1) comprises a dose setting means, an injection means, a removable cap (15) and a cap receiving part (9) adapted to abut or engage with the cap (15) when the cap (15) is mounted on the injection device (1). The dose setting means is operatively coupled to the cap receiving part (9) in such a manner that mounting and / or dismounting of the cap (15) on / from the injection device (1) causes the dose setting means to set a dose. Thereby a correct dose of drug is automatically set during a cap on / cap off cycle. Since such a cycle is normally performed between two subsequent injections, the number of steps required to be performed by the user is reduced.

Description

[0001] This application is an application for a patent with an international filing date of January 23, 2009, titled "Equipment for Injecting Dispensed Dose of Liquid Medicine", and national application number 200980103041.0 (international application number is PCT / EP2009 / 050797) Divisional application. technical field [0002] The present invention relates to an injection device for injecting dispensed liquid medicament doses, eg for injecting a single fixed number of medicament doses or for injecting a limited number of different numbers of medicament doses. More specifically, the present invention relates to an injection device in which the number of manipulation steps required to be performed by the user is minimized. The injection device is particularly suitable for self-injection of liquid medicines such as insulin for the treatment of diabetes by a user. Background technique [0003] In some therapeutic areas, a patient's likelihood of adhering to a given therapy dep...
