Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 to 7, the present invention provides a technical solution: including cylinder 1, be provided with piston head (not shown in the figure) and piston push rod 30 in the cylinder, one side of cylinder is provided with first button 2, the outside of first button is provided with first button cover 3, be provided with buckle 6 in the cylinder lateral wall, for parts such as holding buckle, can outwards thicken one side lateral wall of buckle, then can set up the buckle in the lateral wall of thickening. The utility model discloses a syringe, including cylinder lateral wall, connecting seat, swivel becket, connecting seat, connecting rod, curved bar 13, bottom and sill bar 14, the cylinder lateral wall is provided with slider 7 of many gears draw-in groove on the buckle, and first button is used for driving the buckle dropout, the slider is connected with the connecting rod 9 of cylinder both sides, and the slider is used for driving the connecting rod up-and-down motion of both sides, and the bottom of every connecting rod rotates the one end that is connected with horizontal pole 11 through swivel becket 10, the other end of horizontal pole is connected with connecting seat 12, be provided with curved bar 13 in the connecting seat, the bottom of curved bar is articulated with the one end of sill.

When the utility model is used, firstly, the piston push rod is pulled out in the needle cylinder to suck the gastric perfusion liquid, and the first button is pressed down and the slide block is pushed to the bottom. The elbow was then inserted into the rat's stomach and the curved rod was placed in the rat's mouth. Then the slide block is pushed upwards to drive the connecting rod to move upwards and drive the cross rod and the arc rod to turn outwards as shown in figure 2, thereby opening the mouse mouth. The slider can be blocked by the buckle, avoids the curved bar return. Thus, the mouse mouth can be conveniently opened for gastric perfusion, the relative fixation of the mouse mouth and the needle cylinder can be realized, and the bent pipe can be prevented from being separated by shaking the mouse head. The corner head can be designed to be round and blunt, so that the damage to the experimental rat is reduced; the bent pipe can be made of corresponding soft material PTFE (polytetrafluoroethylene) and has moderate hardness, and due to the design of the ball head at the front end, the damage to the rat can be effectively reduced, and scale marks can be marked on the outer surface of the bent pipe, so that the length of the bent pipe entering the esophagus correspondingly is correspondingly large, and the bent pipe has corresponding reference.

Further, as shown in fig. 3, a second button 4 is disposed on the other side of the syringe, and a second button sleeve 5 is disposed outside the second button.
