Embodiment Construction

[0103] figure 1 and figure 2 Shown is a drug delivery device 10 designed as a pen-type injector. The elongated and tubular housing 18 comprises two housing parts, a proximal body 12 and a distally located cartridge holder 14 . The body 12 and the cartridge holder 14 are interconnected with each other.

[0104] The cartridge holder 14 includes a viewing window 16 and is adapted to receive a tubular cartridge 28, generally having a vitreous body, filled with a liquid medicament. Such as image 3The illustrated cartridge 28, generally has a bottle necked distal portion sealed with a pierceable septum. The distal outlet of the cartridge 28 is generally positioned near the distal face of the threaded receptacle 20 of the cartridge holder 14 . This socket 20 provides a mounting for a needle hub 26 having an injection needle and adapted to be screwed onto said socket 20 .

[0105] Double-ended (double-tipped) needle assembly 26, such as image 3 As shown, the distal septum of...

Abstract

The present invention relates to a drug delivery device for setting and dispensing of a dose of a medicament comprising: - a housing (18) to accommodate a cartridge (28) filled with the medicament, - an electrically operated drive mechanism (32, 34) to be operably engaged with the cartridge (28) to expel a predefined dose of the medicament from the cartridge (28), - at least one dose element (15, 24) displaceably arranged relative to the housing (18) to set and / or to dispense the dose of the medicament, - wherein the dose element (15, 24) and the drive mechanism (32, 34) are mechanically decoupled from each other.

Description

technical field [0001] The present invention relates to a drug delivery device having an electromechanical drive mechanism to dispense predetermined doses of medicament from a cartridge. The electromechanical drug delivery device is particularly suitable for mimicking or simulating the mechanical properties of fully mechanical or manually operated drug delivery devices. Background technique [0002] User operated drug delivery devices are known in the prior art. They are generally applicable where persons without formal medical training, ie patients, need to administer precise and predetermined doses of pharmaceutical preparations such as heparin or insulin. In particular, such devices have use in the case of short-term or long-term, regular or irregular administration of pharmaceutical products. [0003] To accommodate these requirements, such devices must fulfill a variety of requirements. First, the device must be structurally robust, yet easy to use in terms of the us...
