Problems solved by technology

[0008] An additional disadvantage is that when the user tries to remove the cap and sheath from the injection device, he will have to overcome the friction between the cap and the device and the friction between the sheath and the needle at the same time
It may be difficult for users with weak hands or users with poor dexterity to overcome the accumulated force of two frictional interfaces

Abstract

The invention relates to a needle sheath remover comprising a cap (10) removably attached to a housing of a medicament delivery device, a sheath grabber (20) connected to said cap and configured to be engageable to a needle sheath (42) of a medicament container positioned (46) within said medicament delivery device, wherein the cap and the sheath grabber are axially movable in relation to each other and wherein the sheath grabber and the cap are configured to interact with each other such that upon removal of the cap from the housing, the sheath grabber is capable of engaging and removing said needle sheath.

Description

technical field [0001] The present invention relates to an assembly for safe and easy removal of a needle shield of a drug delivery device. Background technique [0002] Many drug delivery devices on the market have been developed for self-administration of drugs, a large number of which are drug injection devices. Many of these injection devices have been provided with a removable needle cover assembly where the cap core is the needle shield. [0003] These sheaths are arranged to protect the injection needle prior to use in order to keep the needle sterile and also prevent the user from being inadvertently needle-sticked. During assembly of the container, needle and sheath, the sheath is pushed onto the neck of the drug container, such as a syringe or cartridge. The sheath may preferably be an elastic material, usually rubber, which ensures a grip and a good seal between the outside environment and the syringe. However, this grip also means that it is relatively difficu...
