Technical Examples

A passively guarded, fillable injection syringe includes an adapter for holding the proximal end of a hollow needle. An inverted plunger is slidingly mounted on the adapter to establish a medicament chamber that is in fluid communication with the needle. Also, a substantially cylindrical needle guard is positioned on the needle for reciprocal axial movement under the influence of a spring which biases the guard and adapter in opposite axial directions. A mechanism is provided such that plunger movements that are required in a typical fill and inject procedure also function to control the position of the guard relative to the needle. Initially, the guard is locked covering the needle tip. A plunger movement unlocks the guard and retracts the guard for syringe filling and injection. Depressing the plunger to complete the injection releases the guard for distal movement under the spring force into a needle protecting position.
