Right part on the upside of be installed with motor, the motor is electrically connected with by wire and controller, the speed changer it is interior
It is movably installed with chamber on the downside of leading screw and guide rod, first containment vessel and is fixedly connected with needle tubing, the inner chamber of the needle tubing
In be movably installed with piston, the lower end of the needle tubing is installed with syringe needle, and the syringe needle includes installing pipe, the installing pipe
Bottom is installed with extraction tube and ventilation is managed.
It is preferred that, the guide rod is located at the both sides of leading screw, and the middle part of the piston is consolidated with the lower end of leading screw and guide rod
Fixed connection.
It is preferred that, the ventilation pipe is positioned at the right side of extraction tube, and the length of ventilation pipe is less than extraction tube.
Compared with prior art, the beneficial effects of the utility model are：The utility model is simple in construction, and control accuracy is high,
Continuous reliable operation, it is adaptable to which medical department carries out micro extraction or injection to medicine to make up a prescription, especially department of medical administration
Door carries out the work that special medicine continuous micro injects transfusion to patient, improves the precision made up a prescription.By setting control
Device, it is possible to achieve micro extraction or injection is accurately carried out to sample, the automaticity of device is improved, by setting
Extraction tube and pipe of taking a breath, can avoid making producing negative pressure in medicine bottle or increase the pressure in the bottle so that pumping decoction is easily, soon
It is prompt, time saving and energy saving；Liquor residue is not had, liquid waste is avoided that.
