Abstract

In an embodiment, an injection actuation assist device is provided, including a top side, a bottom side, an opening in the bottom side for receiving an autoinjector, and an elongated shaft extending between the top side and the bottom side. The device further includes an elongated chamber having a first end and a second end and extending the length of the shaft and terminating at the opening, the chamber being configured to receive a portion of the autoinjector device and comprising a plurality of ribs extending into the chamber for gripping the autoinjector device. The device may further include a notch at the opening for receiving a protrusion of the autoinjector device, when the autoinjector device is received within the chamber, wherein receipt of the autoinjector device within the chamber and movement of the actuation assist device toward the distal end of the autoinjector device, actuates the autoinjector device to deliver an injection.
