Title
(EN) PREFILLED SYRINGE TRAINING DEVICE WITH RELEASEABLY LOCKING NEEDLE GUARD
(FR) DISPOSITIF D'APPRENTISSAGE POUR SERINGUE PRÉREMPLIE AVEC PROTECTION D'AIGUILLE À VERROUILLAGE DÉVERROUILLABLE
Abstract
(EN)
Embodiments provided herein include a resettable injection training device having a body, a plunger slidable relative thereto, an injection simulation member and retractable and extendable shield, wherein the shield releasably locks in a retracted position prior to use. After use of the training device, the shield extends over the injection simulation member to prevent contact with the injection simulation member. Resetting of the slidable shield occurs by applying a force onto a distal end of the shield to retract the shield until a shield locking surface interacts with a locking surface on the body to maintain the shield in a retracted position. Release of the shield from a retracted position to an extended position may occur by moving the plunger toward a distal end of the body until a contact region at a proximal end of the plunger releases the shield locking surface from the body locking surface to release the shield.

Des modes de réalisation de la présente invention concernent un dispositif d'apprentissage d'injection réinitialisable comprenant un corps, un piston pouvant coulisser par rapport à celui-ci, un élément de simulation d'injection et une protection rétractable et extensible, laquelle protection se verrouille avec capacité de déverrouillage dans une position rétractée avant l'utilisation. Après utilisation du dispositif d'apprentissage, la protection s'étend par-dessus l'élément de simulation d'injection pour empêcher un contact avec l'élément de simulation d'injection. La réinitialisation de la protection coulissante s'effectue par application d'une force sur une extrémité distale de la protection pour rétracter la protection jusqu'à ce qu'une surface de verrouillage de la protection interagisse avec une surface de verrouillage sur le corps de façon à maintenir la protection en position rétractée. Le déverrouillage de la protection d'une position rétractée à une position étendue peut s'effectuer par déplacement du piston vers une extrémité distale du corps jusqu'à ce qu'une région de contact à une extrémité proximale du piston libère la protection de la surface de verrouillage du corps pour libérer la protection.
