CONTACT TRIGGER RELEASE TYPE NEEDLE GUARD HAVING ELASTIC SPRING
Document Type and Number:
Japanese Patent JP2022063869
Kind Code:
A
Abstract:
To provide a contact trigger release type needle guard having a suitable elastic spring.SOLUTION: A needle guard device is mountable to a pre-filled syringe in its instantly fillable state. The device includes a device shield interconnected to a lock collar with a flexible member and energized to move relative to the lock collar. The lock collar interfaces with a syringe neck to attach the device to the syringe. As the device shield moves proximally, rotation arms of the lock collar interact with angled cutouts in the device shield, causing the device shield to rotate relative to the lock collar, disengaging one or more keys on the device shield from one or more keyways in the lock collar, and triggering the device shield to move from a first configuration in which the device shield is retractable to expose a syringe sharp part to a second configuration in which the device shield is fixedly positioned to cover the syringe sharp part.SELECTED DRAWING: None
