INJECTOR SAFETY DEVICE

摘要

A safety member (80) for use with an injection device (12) is disclosed. The safety member includes a blocking ring extending into a housing (14) of the injection device in blocking association with a latch member (55) associated with a trigger mechanism (64) 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 (82,64) 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.
