The specific working principle of this embodiment is as follows:
when the medical care personnel use, medical care personnel prepare the liquid medicine and load the liquid medicine into the injector 6, meanwhile, the pressing plate 401 is screwed to one side, the cylinder 601 of the injector 6 is inserted into the needle cylinder mounting mechanism 3 along the accommodating cavity, the finger plate 603 is blocked on the clamping ring 303 to form a limit, then the pressing plate 401 is screwed to the original position, the length of the push plate 404 is adjusted to reach the critical point of liquid medicine extrusion, the inserting plate is mounted in a proper bayonet 107, and the arm is subjected to alcohol wiping and disinfection at the position where the arm needs to be injected, so that the error is prevented, and the range is slightly wider as much as possible. At this time, the fixing mechanism 1 is only required to be fixed at a proper position of the arms of the child, and the fixing mechanism is positioned and fixed through the binding belt 102 and the magic tape 105 on the guard plate 101.
After the fixing is finished, a switch on the controller is started; the ejection mechanism 2 is started, the push-pull electromagnet 205 is electrified to push the pressing block 214 to move forwards, the pressing block 214 and the cylinder 210 are fixedly connected into a whole, and the positioning clamping block 211 is impacted by the convex block 215 at the upper end of the stop rod 204 due to the resistance action of the spring a212 to form impact force; the bottom of the stop rod 204 is provided with a spring c216, the middle end of the stop rod is provided with a connecting rod 217, and the stop rod 204 sinks under the action of the connecting rod 217 while the pressing block 214 pushes the stop rod, so that the push rod 203 is ensured to be ejected smoothly; the front end of the spring B213 after pushing out is provided with a baffle B208, and the baffle B rebounds to the original position under the action of the tension of the spring B213; the push rod 203 is momentarily ejected, and the front end fixing plate 218 drives the syringe mounting mechanism 3 and the injection mechanism 4 to form injection displacement to prick into the deltoid muscle of the arm along the avoidance hole 507 on the extrusion tube 502.
At this time, the injection mechanism 4 is started, the motor 402 starts to operate, and the screw 403 rotates to drive the push plate 404 to slowly move forwards; the platen 401 begins to squeeze the syringe 6 plunger 602 as the push plate 404 moves, forming the injection of drug solution.
After the injection is finished, the electromagnetic valve is started, and the push rod 203 is pulled to return to the original position; the needle leaves the skin, and at this time, the electric push rod 503 pulls upwards to suck the cotton ball in the cotton ball tube 505 filled with cotton ball into the extrusion tube 502, and pushes down the telescopic rod to press the cotton ball along the extrusion tube 502 at the injection needle hole, and after a certain time of pressing, the whole set of device is directly taken down to complete the injection task.
In addition, a novel acousto-optic control toy can be arranged on the support 103, so that the children can be attracted, and the injection work can be smoothly completed in the playing process.
