Problems solved by technology

The needle tip cap engages the needle shield through a protrusion and recess design, which requires a relatively complex manufacturing process for functionality
This complexity results in a higher price and also requires the syringe assembly to be pre-assembled with the needle tip cap and needle shield and syringe prior to packaging

Embodiment Construction

[0015] Such as figure 1 As shown in the example in , the device (1) according to the invention comprises a wall (2) having an inner surface (21) and an outer surface (22), the inner surface (21) of the wall defining a rigid wall along the syringe (7). A tubular hollow portion (3) of the longitudinal axis of the needle shield (6), said inner wall comprising a recess (4) adapted to accommodate a compressible washer (5) capable of being placed in said recess moving along the longitudinal axis from a recess portion in which the gasket is in a relatively uncompressed state to a recess portion in which the gasket is in a relatively compressed state as compared to a relatively uncompressed state, wherein the recess is arranged such that the gasket is in compression Clamp the rigid needle shield (6) in this state.

[0016] Due to the simple design and ease of use of the device according to the invention, there is no need to pre-assemble the syringe in the packaging provided to the e...

Abstract

A device for safely and easily removing a rigid needle shield from a syringe, the device comprising a wall having an inner surface and an outer surface, the inner surface of the wall defining a tubular shape along the longitudinal axis of the rigid needle shield a hollow portion, the inner wall including a recess adapted to receive a compressible washer movable within the recess along the longitudinal axis from a portion of the recess in which the washer is in a relatively uncompressed state into which and A recess portion of the gasket in a relatively compressed state compared to an uncompressed state, wherein the recess is arranged such that the gasket grips the rigid needle shield in the compressed state.

Description

technical field [0001] The present invention relates to a device and method for safe and easy removal of a needle shield element from a medical syringe. Background technique [0002] It is becoming more and more common for users to inject medical products themselves, for example diabetics etc. Syringes are usually covered with a needle shield to prevent accidental injections. In some cases, the needle shield can be rigid and referred to as a rigid needle shield (RNS). Removing the rigid needle shield may be difficult for certain user groups with reduced hand strength and mobility. This is the case, for example, for rheumatoid arthritis users. Standard rigid needle shields are small and provide a grip that may not be suitable, for example, for users with rheumatoid arthritis. These users may not be able to remove the syringe's shield at all. Accidents have been reported after some users attempted to use unsafe methods such as using their teeth to remove the syringe shiel...
