Embodiment Construction

[0118] refer to figure 1 , shows a drug delivery device 10 in the form of a pen-type injector. The drug delivery device 10 comprises a dose setting member 12 serving as a dose setting and delivery mechanism, a cartridge holder 14 and a removable cap 16 . The proximal end 15 of the cartridge holder 14 and the distal end 13 of the dose setting member 12 are removably secured together. Pen injectors may include reusable or disposable pen injectors. Where the syringe comprises a reusable device, the cartridge holder 14 and dose setting mechanism are removably coupled together. In disposable devices, they may be permanently coupled together. The removable cap 16 can be releasably retained over the cartridge holder 14 when the drug delivery device is not in use.

[0119] The cartridge holder contains a removable cartridge 20 containing a medicament 25 . refer to figure 1 , the cartridge holder 14 accommodates a removable cartridge 20 . figure 2 shows the available figure 1 ...

Abstract

Disclosed herein are cartridge assemblies (300) that include coding features (318) that help dedicate a medicament reservoir to specific injection devices. An exemplary cartridge assembly (300) comprises a cylindrical inner surface for holding medicament and a cylindrical outer surface comprising at its proximal end one or more stops configured as coding elements (318) protruding from the cylindrical outer surface. Each coding element (318) is configured only to engage a corresponding coding feature (330) on a dose setting and delivery mechanism (302), thereby allowing only the correct cartridge assembly (300) to connect to the dose setting and delivery mechanism (302).

Description

technical field [0001] The present patent application relates generally to medical delivery devices comprising a cartridge assembly and a dose setting member, and in particular to a cartridge assembly having marking features, such as stop features, which engage complementary marking features on the dose setting member , such as a counter stop feature, to ensure that the proper cartridge assembly is connected to the proper dose setting member. Background technique [0002] Medicament reservoirs such as ampoules, cartridges or vials are generally known. Such reservoirs are used in particular for medicaments which can be administered by the patient himself. For example, with regard to insulin, a diabetic patient may need to inject a certain amount of insulin via a pen-type injection syringe or infuse via a pump. With some known reusable pen-type drug delivery devices, the patient loads a cartridge containing insulin into a cartridge holder. The cartridge plus the retainer fo...
