[0025] The working principle of the present invention is as follows: 1. Extracting serum: Slide the liquid storage tank 5 loaded with serum into the sleeve 204 (the liquid storage tank 5 is an existing vacuum blood collection bottle with a diaphragm 6. These bottles have a special design to prevent contamination and ensure the accuracy of blood samples). The liquid storage tank 5 will hermetically seal the circular hole, dock the upper tank body 101 with the upper end of the lower tank body 102 and press the upper tank body 101. The upper tank body 101 will squeeze the partition disc 212 to slide in the lower tank body 102. The squeezed partition disc 212 will squeeze the corrugated compression tube 205, so that the air in the corrugated compression tube 205 enters the compression space through the air outlet 209, the air outlet 207 and the air inlet groove 103 in turn, so that the air pressure in the compression space increases, thereby pushing the airbag 301 in the upper tank body. 101 descends (the sum of the air pressure thrust and the gravity is greater than the friction between the airbag 301 and the inner wall of the upper tank body 101, but the airbag 301 will only slide and descend on the inner wall of the upper tank body 101 without deformation), during the descent of the airbag 301, the first solenoid valve 303 is in the open state, and the second solenoid valve 304 is in the closed state (when the external voltage is energized through the coil in the solenoid valve, an electromagnetic field will be generated to drive the movement of the valve core), and at the same time, when the airbag 301 descends, it will drive the needle 308 to descend together. As the corrugated compression tube 205 is continuously compressed, the needle 308 will pierce into the through hole 210 (the inner diameter of the through hole 210 is smaller than the outer diameter of the needle 308), and the through hole 210 will be airtightly slidably connected with the outer wall of the needle 308. After passing through the through hole 210, it passes through the circular hole and pierces the diaphragm 6 to enter the liquid storage tank 5. When the corrugated compression tube 205 is compressed to the limit, the lower end surface of the upper tank body 101 will contact the electromagnetic ring 206, and the airbag 301 will be driven down to drive the annular magnet 306 to contact the electromagnetic ring 206 to generate resistance. The airbag 301 will be compressed and deformed by the air pressure in the compression space due to the resistance generated by the contact between the annular magnet 306 and the electromagnetic ring 206, and the liquid storage bag 302 arranged inside will change from an elliptical shape to a slightly flat shape due to the deformation of the airbag 301 (a first spring 305 is provided in the airbag 301 to form an elastic force), and the electric contact 307 will slide into the power-on hole 211 to contact the conductive block and energize it, and the electric contact 307 will also send electricity to the electromagnetic ring 206 at the same time. The voltage is transmitted to make the electromagnetic ring 206 generate magnetism. When the electromagnetic ring 206 generates magnetism, it will generate magnetic repulsion with the annular magnet 306. The magnetic repulsion will drive the annular magnet 306 to slowly move upward in the upper tank body 101. The rising annular magnet 306 will drive the airbag 301 and the liquid storage capsule 302 to move upward together, and the compressed airbag 301 and the liquid storage capsule 302 will change from a flat shape to an original elliptical state (negative pressure is generated during the deformation process), and then the serum in the liquid storage tank 5 will be sucked into the liquid storage capsule 302 through the needle 308. As the rising annular magnet 306 continuously drives the airbag 301 and the liquid storage capsule 302 to slide and rise on the inner wall of the upper tank body 101, the electric contact 307 will slide and disengage from the power-on hole 211, and the power supply will be disconnected.The relay disconnects the voltage supplied to the first solenoid valve 303, so that the valve core of the first solenoid valve 303 is closed, and supplies voltage to the second solenoid valve 304, so that the valve core of the second solenoid valve 304 is opened; The continuously rising driving airbag 301 and liquid storage bag 302 will further compress the airbag 301 and liquid storage bag 302 in the process of rising to the top of the upper tank body 101, and cooperate with the air pressure annular magnet 306 in the compression space (the magnetic repulsion generated by the electromagnetic ring 206 and the annular magnet 306 and the air pressure in the compression space must be greater than the elastic force of the first spring 305), so that the liquid storage bag 302 is transformed from an elliptical shape to a completely flat shape. The compressed liquid storage bag 302 will cause the serum extracted inside to be transported to the connecting tube 309, the telescopic tube 310 and the L-shaped tube 311 through the second electromagnetic valve 304 opened by the valve core, and finally discharged into the immersion tank 312 to mix with the test paper (after the blood or serum contacts the test paper, the test paper will display the result within a few seconds). After the test time is over according to the provisions of the existing medical serum test paper, the transparent plate 315 is removed, and the test paper is taken out to observe the result; In general, the upper tank body 101 and the lower tank body 102 slide against each other to generate air pressure in the compression space, and the air bag 301 and the liquid storage bag 302 are driven to descend in the upper tank body 101 by the air pressure. During the descent, the needle 308 is inserted into the liquid storage tank 5. As the air bag 301 and the liquid storage bag 302 continue to descend, they are compressed and deformed by resistance. Then, the electric contact 307 and the power-on hole 211 are energized to generate magnetic repulsion between the electromagnetic ring 206 and the annular magnet 306, so as to drive the air bag 301 and the liquid storage bag 302 to rise, further compress the liquid storage bag 302, and cause the air pressure in the liquid storage bag 302 to change. The serum in the liquid storage tank 5 is sucked into the liquid storage capsule 302 for temporary storage, and the electromagnetic ring 206 and the annular magnet 306 generate magnetic repulsion, which continuously drives the airbag 301 and the liquid storage capsule 302 to rise, and the airbag 301 and the liquid storage capsule 302 are compressed again, so that the serum temporarily stored in the liquid storage capsule 302 enters the immersion tank 312 through the connecting tube 309, the telescopic tube 310 and the L-shaped tube 311 to mix with the test paper for detection. The whole process only requires pressing the upper tank body 101, which simplifies the detection steps, reduces the difficulty and improves the detection efficiency, avoids the contact between the serum and the test paper and the outside air during the detection process, reduces the error, and improves the credibility of the detection result; 2. Cleaning: After the sampling and testing is completed, the liquid storage tank 5 is taken out, the lower tank body 102 is placed on a flat table or the round hole of the lower tank body 102 is sealed with tape, and the upper tank body 101 is pressed again to slide on the inner and outer walls of the lower tank body 102 to increase the air pressure in the compression space. The third solenoid valve 408 is opened by the controller, and the air in the compression space will pass through the third solenoid valve 408 and enter between the slide plate 404 and the external box 403, so that the air pressure in the external box 403 is increased, and the slide plate 404 is pushed to drive the arc magnet 406 to approach the armature 410, so that the armature 410 rotates (when the external power supply provides voltage to the armature 410, the armature 410 itself will generate a magnetic field. If there is an external magnet (arc magnet 406) Close to the armature 410, this magnetic field interacts with the voltage in the armature 410. According to Faraday's law of electromagnetic induction, the change of the magnetic field will induce an electromotive force in the armature 410, and this changing magnetic field can cause the armature 410 to rotate). The rotating armature 410 will drive the rotating barrel 411 and the fan blades 413 to rotate, allowing the cleaning water inside the fixed box 402 to enter the rotating barrel 411 through the water inlet hole. As the rotating barrel 411 and the fan blades 413 rotate, the cleaning water generates centrifugal force in the rotating barrel 411 and enters the delivery pipe 414 and the injection pipe 415 through the one-way valve 416 and enters the L-shaped pipe 311. Part of the cleaning water will enter the immersion tank 312 through the L-shaped pipe 311, and the other part of the cleaning water will pass through The inner wall of the telescopic tube 310 and the connecting tube 309 enters the liquid storage bag 302, and because the air pressure in the compression space flows into the three-way pipe 407 through the third solenoid valve 408, the air pressure in the compression space cannot increase to drive the air bag 301 to descend in the upper tank body 101. After descending for a certain period of time, the controller closes the third solenoid valve 408, and then repeatedly presses the upper tank body 101 to slide on the inner and outer walls of the lower tank body 102, so that the air pressure in the compression space increases, driving the air bag 301 to descend, allowing the electrical contact 307 to contact the power-on hole 211 to energize, and the relay will open the second solenoid valve 304 and close the first solenoid valve 303, so that the cleaning water in the telescopic tube 310 and the connecting tube 309 enters the liquid storage bag 302 to rinse the interior, and then release the upper The tank body 101 allows the air pressure in the compression space to gradually decrease as the upper tank body 101 rises, and finally separates the upper tank body 101 from the lower tank body 102. The energized electrical contact 307 and the energized hole 211 are disconnected, which will close the second solenoid valve 304 and open the first solenoid valve 303 through the relay. The cleaning water flushed in the liquid storage capsule 302 will flow into the needle 308 due to the opening of the first solenoid valve 303, thereby completing the flushing of the needle 308, the liquid storage capsule 302, the connecting tube 309, the telescopic tube 310 and the inner wall of the L-shaped tube 311. At the same time, the cleaning water entering the immersion tank 312 will also flush the immersion tank 312. The cleaning water in the immersion tank 312 can be allowed to flow out by pulling out the plug 314, so as to facilitate reuse next time. It should be noted that, in the process of repeatedly pressing the upper tank body 101 to slide on the inner and outer walls of the lower tank body 102, the air pressure in the compression space increases and drives the airbag 301 to descend. Negative pressure will also be generated inside the airbag 301 and the liquid storage bag 302. When the electric contact 307 contacts the power-on hole 211 and energizes to open the valve core of the second solenoid valve 304 and close the valve core of the first solenoid valve 303, the negative pressure generated in the liquid storage bag 302 will suck the cleaning water in the telescopic tube 310 and the connecting tube 309 into the liquid storage bag 302, which can enhance the flushing effect. The above-mentioned flushing method of cleaning the inner wall of the needle 308, the liquid storage bag 302, the connecting tube 309, the telescopic tube 310 and the L-shaped tube 311 can be repeated several times to achieve a better cleaning effect, and the outer wall of the needle 308 is cleaned by soaking in cleaning water.
