Otherwise, this embodiment is identical to embodiment 1, and will not be described herein.
The specific working principle of this embodiment is as follows:
when the device is used, medical staff prepares liquid medicine and loads the liquid medicine into the injector 6, simultaneously rotates the pressing plate 401 to one side, inserts the cylinder 601 of the injector 6 into the needle cylinder installation mechanism 3 along the accommodating cavity, the finger plate 603 blocks the clamping ring 303 to form limiting, then rotates the pressing plate 401 to the original position, adjusts the length of the pushing plate 404 to reach the critical point of liquid medicine extrusion, then installs the inserting plate in the proper bayonet 107, and then wipes and disinfects the position of the arm needing to be injected with alcohol, and the range is a little larger as possible in order to prevent errors. At this time, the fixing mechanism 1 is only required to be fixed at a proper position of the arm of the child, and the positioning and fixing are performed through the strap 102 and the magic tape 105 on the guard plate 101.
After the fixation, starting a switch on the controller; when 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 is fixedly connected with the cylinder 210 into a whole, and the resistance action of the spring a212 enables the positioning clamping block 211 to be accumulated to be punched out of the convex block 215 at the upper end of the stop rod 204 to form impact force; the bottom of the stop rod 204 is provided with a spring c216, and the middle end of the stop rod is provided with a connecting rod 217, so that the stop rod 204 sinks under the action of the connecting rod 217 while the pressing block 214 pushes, and the push rod 203 is ensured to pop out smoothly; the front end of the spring B213 after being pushed out is provided with a baffle B208 which rebounds to the original position under the tension action of the spring B213; the push rod 203 is popped up instantaneously, the front fixing plate 218 drives the syringe mounting mechanism 3 and the injection mechanism 4 to form injection displacement and insert the arm deltoid along the position-avoiding hole 507 on the extrusion tube 502.
At this time, the injection mechanism 4 is started, the motor 402 starts to operate, and the lead screw 403 rotates to drive the push plate 404 to move forwards slowly; the pressing plate 401 starts to press the core pin 602 of the syringe 6 by the movement of the pushing plate 404, thereby forming the injection of the liquid medicine.
After injection is finished, the electromagnetic valve is started, and the push rod 203 is pulled to return to the original position; when the needle head leaves the skin, the electric push rod 503 is pulled upwards to suck the cotton balls in the cotton ball tube 505 which is pre-filled with the cotton balls into the extrusion tube 502, then the telescopic rod is pushed downwards to press the cotton balls at the injection needle holes along the extrusion tube 502, and after the cotton balls are pressed for a certain time, the whole device is directly taken down to complete the injection task.
