Abstract
A safety member for use with an injection device is disclosed. The safety member includes a blocking ring extending into a housing of the injection device in blocking association with a latch member associated with a trigger mechanism of the injector, in which the blocking ring blocks movement of a portion of the trigger mechanism into a firing position. The safety member further includes a manipulable portion disposed outside the housing and configured for hand-manipulation by a user to remove the safety member from the housing to unblock the firing mechanism to enable firing of the injector.
