Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1 to 7, the present invention provides a technical solution: including cylinder 1, be provided with piston head (not shown) 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, in order to accommodate parts such as buckle, can outwards thicken the lateral wall of one side of buckle, then can set up the buckle in the lateral wall of thickening. The utility model discloses a syringe, including needle cylinder, connecting seat, slider 7 that is provided with the multispeed draw-in groove on the buckle, first button are used for driving the buckle and release, the slider is connected with the connecting rod 9 of needle 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 is connected with the one end of horizontal pole 11 through rotation ring 10 rotation, the other end of horizontal pole is connected with connecting seat 12, be provided with arc pole 13 in the connecting seat, the bottom of arc pole is articulated with the one end of sill bar 14, and the other end of sill bar is fixed in the needle cylinder bottom outside, and both sides arc pole is crooked to opposite direction, the bottom intercommunication of needle cylinder has return bend 15.
When the invention is used, firstly, gastric juice is sucked into the needle cylinder by pulling out the piston push rod, the first button is pressed down, and the sliding block is pushed to the lowest. The elbow was then inserted into the rat stomach and the curved rod was placed in the rat's mouth. And then the sliding block is pushed upwards to drive the connecting rod to move upwards to drive the cross rod and the arc-shaped rod to turn outwards, as shown in fig. 2, so that the mouse mouth is opened. The sliding block can be clamped by the buckle, and the return of the arc-shaped rod is avoided. Thus, the mouse mouth is conveniently opened to irrigate the stomach, and meanwhile, the relative fixation of the mouse mouth and the needle cylinder is realized, so that the elbow is prevented from being separated due to shaking of the mouse head. The head of the elbow can be designed to be round and blunt, so that the damage to experimental rats is reduced; the bent pipe can be made of corresponding soft material PTFE (polytetrafluoroethylene), has moderate hardness, can effectively reduce damage to rats due to the design of the ball head at the front end, can be marked with scale marks on the outer surface, and has corresponding references on how long the bent pipe can enter the esophagus.
