摘要：
An apparatus includes a medicament container assembly, a movable assembly, and a spring. The medicament container assembly includes a first plunger defining a first volume, and a second plunger defining a second volume. The movable assembly includes a first movable member and a second movable member. The second movable member can move the second plunger within the medicament container assembly. The first movable member can move the first plunger in a first direction within the medicament container assembly to expel contents of at least the first volume via a needle. The spring is configured to urge the needle in a second direction. The release portion of the first movable member is configured to contact the second movable member after the first movable member moves the first plunger to enable the spring to move the needle in the second direction.
