Be not shown) and piston push rod 30, the side of the syringe be provided with the first button 2, is provided on the outside of first button
One knob covers 3, is provided with buckle 6 in the barrel sidewall, can be past by the side side wall of buckle in order to accommodate the components such as buckle
External upset (EU) buckle can be then arranged in the side wall of thickening.The barrel sidewall is provided with multi gear position card slot on buckle
Sliding block 7, for driving buckle tripping, the sliding block connect the first button with the connecting rod 9 of syringe two sides, and sliding block is used to drive
The connecting rod of two sides moves up and down, and the bottom end of each connecting rod is rotatably connected to one end of cross bar 11 by swivel becket 10, described
The other end of cross bar is connected with attachment base 12, and curved rod 13, bottom and the bottom bar 14 of curved rod are provided in the attachment base
One end is hinged, and the other end of bottom bar is fixed on syringe bottom outside, and two sides curved rod is to be bent to relative direction, the syringe
Bottom is communicated with bend pipe 15.
The present invention when in use, sucks stomach-filling liquid by pulling out piston push rod first in syringe, presses first
Knob simultaneously shifts sliding block onto bottom.Bend pipe is then inserted into the stomach of rat, and curved rod is placed in the oral area of rat.And
Sliding block is up pushed afterwards, connecting rod is driven to move up, cross bar and curved rod is driven to turn up, as shown in Fig. 2, to strut mouse mouthful.
Sliding block can be snapped and block, and avoid curved rod return.Stomach-filling is carried out convenient for opening mouse mouthful in this way, while realizing mouse mouthful and syringe
It is relatively fixed, avoid mouse head from shaking so that bend pipe is detached from.Bend pipe head can be designed to round blunt, and the damage of experimental rat is subtracted
It is few；Bend pipe can use corresponding soft material PTFE (polytetrafluoroethylene (PTFE)), have more moderate hardness, along with the ball of front end
Head design, can effectively reduce the damage to rat, and can be marked with graduation mark outside, how long enter esophagus accordingly, have
Corresponding reference.
Further, as shown in figure 3, the other side of the syringe is provided with the second button 4, the outside of second button
It is provided with the second knob set 5.Second button can be fixed and can not press, and the button of such two sides can be used for finger card
