An apparatus involving a syringe body, a needle, a pre-filled cartridge, and a guard is described. In some versions, a distal bung or a stopper is also used. The apparatus may also have a passive release mechanism, which releases the guard. In some versions, the distal bung or stopper may be used with the pre-filled cartridge. In some versions, the guard is able to move distally in response to actuating the passive release mechanism. As the guard moves distally, the guard is able to cover a portion of the needle. |
