Embodiment Construction

[0043] The cap removal tool includes a pair of opposing jaws connected by a resilient connection about which the pair of opposing jaws are pivotable.

[0044] Each jaw includes a distal portion configured to surround at least a portion of the cap, and a proximal portion configured to cooperate with a component of the medical injection device other than the cap. More precisely, the medical injection device preferably comprises a body from which the needle extends distally. The body may be: a barrel of a syringe; a housing of a safety device surrounding the barrel of a syringe; a housing of an injection device configured to receive the barrel of a syringe; an ergonomic housing, and the like.

[0045]The proximal portion of the jaw preferably includes connection means configured to axially attach the removal tool to the body of the medical injection device. The connection means is configured to axially secure the removal tool to the body. The attachment means may comprise one o...

Abstract

The invention relates to a tool (1) for removing a cap (3) from a medical injection device comprising a body and a needle extending distally from the body, and the cap covers the needle. The tool is characterized by comprising a pair of opposite jaws (10, 11) connected by an elastic interface (12), wherein each jaw comprises a distal portion (10b, 11b) forming a distal clamp configured to surroundat least a part of the cap; a proximal portion (10a,11a) forming a proximal clamp configured to be removably axially fixed to a body of the medical injection device; an elastic interface forming a fulcrum (12) located between the distal and proximal portions such that a pinching force exerted radially inwardly onto the distal portion (10b, 11b) of the jaws causes the proximal portion (10a, 11a) of the jaws to expand radially outwardly. The tool is operable between a rest position wherein the proximal portion (10a, 11a) of the jaws rigidly engages the body of the medical injection device, thedistal portion (10b, 11b) of the jaws being distant from the cap, and an operative position wherein the distal portion (10b, 11b) of the jaws is pinched so that the distal portion (10b, 11b) engages the cap and the proximal portion (10a, 11a) disengages from the body of the medical injection device.

Description

technical field [0001] The present invention relates to a tool for removing caps from medical injection devices. Background technique [0002] Medical injection devices comprising needles are usually closed by a cap which protects the needle from external impact and / or contamination, ensures a fluid-tight closure of the contents of the medical injection device, and also protects the user from needle sticks harm. Depending on the application, the cap can be: a needle shield made of a soft material such as rubber, TPE (thermoplastic elastomer), or another elastomer; a rigid shield made of a substantially rigid material such as plastic; or include an arrangement Rigid needle shield for needle shield in rigid shield. [0003] When the cap is placed on the medical injection device, the needle tip penetrates the distal portion of the needle shield (if present), or in the absence of any needle shield, at a distance from the inner surface of the rigid shield. Furthermore, the pro...
