ABSTRACT:
An injection device useful either for manual injection or mechanical injection, comprises a cross frame having the shape of a revolver. A removable injection syringe having a syringe piston and at least one needle, is mounted on the cross frame, and a syringe cradle secures the syringe to the cross frame. A device is provided for positioning the penetration and to predetermine the degree of penetration of the needle. There is a trigger on the cross frame, and a pawl is actuated by the trigger. The pawl rotates a barrel step by step upon repeated actuation of the trigger. A screw-threaded axle is rotated by the barrel, and a screw-threaded slider is in screw-threaded engagement with the screw-threaded axle and moves forward upon rotation of the axle. The slider and the syringe piston are interconnected to advance the syringe piston stepwise upon repeated actuation of the trigger.
