AI Technical Summary
Technical Problem
Existing needle covers for medical injection devices require a high pull-out force for removal, which can be challenging for users with reduced strength and may lead to injury or needle bending during removal.
Method used
A needle cover design featuring an inner needle shield with elastomeric properties and an outer needle shield with a radially movable actuator, including flexible arms with tilted surfaces, that facilitates removal by converting radial force into axial force through a wedge effect.
Benefits of technology
The design significantly reduces the pull-out force required for removing the needle cover, making it easier for users to access the needle while maintaining a secure seal, thereby reducing the risk of injury and needle damage.
