Abstract
The delivery of a fluid cutaneously is effected by generating a suction force on a surface of a housing. A surface of a cutaneous layer is received under the suction force about which the proximal end of a needle thereby to pierce the cutaneous surface and to effect an injection of fluid. There is generated a suction force to operate the movement of a needle in the housing. The needle is moved under the suction force from the housing thereby to permit piercing a cutaneous layer. The bladder for containing fluid is emptied under the suction into the distal end of the needle and thereby permit the expulsion of fluid through the proximal end of the needle for injection below the cutaneous layer.
