Abstract

An electrically powered machine for actuating a medical injection syringe. The body of the syringe is clamped to the machine which has a motor-rotated screw which displaces a ram to advance the piston of the syringe. The machine can be fitted with syringes having a wide range of volumetric displacement characteristics. Syringe delivery rate is controllable to within 3% at rates between 0.2 and 100 cubic centimetres per hour. The machine can be programmed for the syringe to deliver at different rates in several successive periods. An audible/visual alarm pref. notifies any malfunction.
