Title
(EN) MUSCLE WIRE ESCAPEMENT ACTIVATION ASSEMBLY FOR A DRUG DELIVERY DEVICE
(FR) ENSEMBLE D'ACTIVATION D'ÉCHAPPEMENT DE FIL DE MUSCLE POUR UN DISPOSITIF D'ADMINISTRATION DE MÉDICAMENT
Abstract
(EN)
Drug delivery devices are described that include an escapement activation assembly. The escapement activation assembly includes a slide having a plurality of pallet engagement portions and a switch engagement portion and a pallet having a plurality of slide engagement portions. A drive is coupled to the pallet to cause the pallet to move relative to the slide to move the plurality of slide engagement portions into and out of engagement with the plurality of pallet engagement portions to allow the slide to move along a path within the drug delivery device. Movement of the slide can cause the switch engagement portion to move out of engagement with an activation trigger of a mechanism of the drug delivery device.
(FR)
La présente invention concerne des dispositifs d'administration de médicament qui comprennent un ensemble d'activation d'échappement. L'ensemble d'activation d'échappement comprend une glissière ayant une pluralité de parties de mise en prise avec une palette et une partie de mise en prise avec un commutateur, et une palette ayant une pluralité de parties de mise en prise avec une glissière. Un pilote est couplé à la palette pour amener la palette à se déplacer par rapport à la glissière afin de déplacer la pluralité de parties de mise en prise avec une glissière en prise et hors de prise avec la pluralité de parties de mise en prise avec une palette pour permettre à la glissière de se déplacer le long d'un trajet à l'intérieur du dispositif d'administration de médicament. Le déplacement de la glissière peut amener la partie de mise en prise avec un commutateur à se déplacer hors de prise avec un élément de déclenchement d'activation d'un mécanisme du dispositif d'administration de médicament.
