Abstract

An auto-injection device has separable front and rear housing portions. The rear portion contains a drive assembly 88 which is triggered or unlatched by rearward movement of an actuating sleeve 14 extending from the front portion. A locking dial 16 may be provided which locks the actuating sleeve 14 against rearward movement until the dial is moved to an unlocked position. The dial automatically returns to a locked position upon initial rearward movement of the actuating member 14, so that, when the actuating member 14 moves forwardly after completion of an injection, it locks out to shroud the needle of the auto-injection device.
