Piston rod slowly moves, and realizes accurate gavage；
（2）Piston rod is promoted to move by rotating swivel head, compared to the mode that tradition pushes directly on piston rod, operation is more
Add conveniently, it is easier to control the amount and speed of gavage；
（3）Operation for conventional gavage amount, syringe graduation line are ring-type groove at 0.2 and 0.4ml, experimenter
Can be in this, as with reference to gavage amount be controlled, for the accurate operation for controlling gavage amount of needs, all graduation marks are equal on syringe
For ring-type groove, operating personnel can be clearly seen scale in any angle, understand real-time gavage progress；
（4）Pigment filled layer is equipped with pintle wall, the pigment of different colours can be filled in filled layer, easy to difference
Medicine carries out distinguishing different gavage syringe needles during gavage operation, avoids confusion；
（5）Gastric perfusion needle is staight needle, and the shape of pin meets the physiological camber behind small white mouse Baoding, mouse is pierced during gavage
Swash few；
（6）The smooth circular arc in syringe needle end of gastric perfusion needle, prevents that gastric perfusion needle causes to damage to the stomach wall of mouse during gavage；
（7）The side wall of the swivel head or upper surface are equipped with equally distributed rotating scale, and the helical pitch of screw is 1mm,
Spin head one encloses, and piston pad just moves a scale（1mm）, the precision of gavage can further lift 0.001ml.
