The insides of the two receiving grooves 202 are slidably connected with first slide plates 204, and the sides of the two first slide plates 204 that are away from each other are fixedly connected with protrusions 205, and the sides of the two first slide plates 204 that are close to each other are fixedly connected with second springs 206. The piston plate 201 and the first slide plates 204 are evenly provided with ventilation holes 207, and the top of the piston plate 201 is fixedly connected with a protrusion 205. A telescopic rod 208 is fixedly connected, and the top of the telescopic rod 208 is slidably connected to the inner wall of the cylinder 209. The two sides of the piston plate 201 are respectively slidably connected to the two second slide plates 210. The top of the second slide plate 210 is fixedly connected with a plurality of teeth 211. The top of the second slide plate 210 is meshed with the second gear 212 through the teeth 211. The top of the second gear 212 is meshed with a third tooth plate 213. The third tooth plate 213 and the side of the second slide plate 210 close to the piston plate 201 are fixedly connected with an inclined block 214.

[0035] The slide groove 203 is communicated with the storage groove 202, the first slide plate 204 is elastically connected to the inner wall of the storage groove 202 through the second spring 206, the protrusion 205 penetrates the inner wall of the storage groove 202 and extends to the inside of the slide groove 203, the size of the protrusion 205 is adapted to the size of the slide groove 203, the second slide plate 210 is close to the side of the piston plate 201 and abuts against the protrusion 205, the bottom of the cylinder 209 is fixedly connected to the top of the main body shell 301, the telescopic rod 208 penetrates the top of the main body shell 301 and extends to the inside of the liquid storage tank 303, the piston plate 201 is slidably connected to the inner wall of the liquid storage tank 303, the rotating shaft 311 penetrates the piston plate 201 and extends to the bottom of the piston plate 201, the third tooth plate 213 and the second slide plate 210 are both slidably connected to the inner wall of the fourth slide groove 309, the second gear 212 is rotatably connected to the inner wall of the fourth slide groove 309, and the friction coefficient of the inner wall of the fourth slide groove 309 is relatively large.

[0036] The detection mechanism 4 includes a blood viscometer 401, a sliding frame 402 is fixedly connected to the side of the blood viscometer 401, a limiting groove 403 is provided inside the sliding frame 402, three blood-carrying discs 404 are arranged on the blood viscometer 401, the main shell 301 is slidably connected to the limiting groove 403 through the limiting plate 302, the end of the liquid outlet head 305 away from the main shell 301 is aligned with the blood-carrying disc 404, and the main shell 301 is located above the blood viscometer 401.

[0037] The above scheme is adopted: by setting the cooperation of the second slide plate 210 and the inclined block 214 and other structures, the second slide plate 210 and the inclined block 214 facilitate the conversion of the piston plate 201 between the working state and the ready state. During the upward movement of the piston plate 201, the protrusion 205 will first abut against the fixed inclined block 214 on the third tooth plate 213. Because the friction coefficient of the inner wall of the fourth slide groove 309 is large, the protrusion 205 will be moved to the inside of the storage groove 202 by squeezing the inclined surface of the inclined block 214, and the second spring 206 will be squeezed by the first slide plate 204, so that the first slide plate The vent hole 207 on the third tooth plate 213 is gradually misaligned with the vent hole 207 on the piston plate 201 to prevent the air in the upper and lower areas of the piston plate 201 from communicating with each other. When the protrusion 205 is completely squeezed into the receiving groove 202, the inclined block 214 on the third tooth plate 213 will abut against the top of the piston plate 201, and the inclined block 214 drives the third tooth plate 213 to slide into the fourth slide groove 309 by squeezing the inclined surface, so that the second gear 212 rotates and the second slide plate 210 slides in the direction close to the piston plate 201 through the teeth 211, and finally the second slide plate 210 moves The second slide plate 210 moves to the inside of the chute 203 and abuts against the protrusion 205. Since the friction coefficient of the inner wall of the fourth chute 309 is relatively large, the second slide plate 210 will not be reset under the elastic force of the second spring 206. When the piston plate 201 moves downward to the position abutting against the top of the stirring paddle 312, the bottom of the piston plate 201 will squeeze the inclined block 214 on the second slide plate 210. By squeezing the inclined surface, the inclined block 214 drives the second slide plate 210 to move to the inside of the fourth chute 309, and the abutment with the protrusion 205 is released. At this time, the first slide plate 204 will be elastically released by the second spring 206. Under the action of force, the protrusion 205 is driven to reset, and at this time, the piston plate 201 is realigned with the vent hole 207 on the first slide plate 204. Each link cooperates with each other, so that each batch of injection operations can be carried out under the same conditions, thereby improving the accuracy and stability of injection, and can continuously carry out multiple batches of injection operations to meet the needs of batch blood sample testing, and automatically realize state conversion during the movement process, which can shorten the device preparation time and improve the device's injection efficiency, which can meet the needs of rapid testing of a large number of blood samples in modern medical testing.

[0038] The working principle and use process of the present invention are as follows: first, in the preparation stage, the device needs to use the cylinder 209 to move the telescopic rod 208 upward, driving the piston plate 201 upward until the top of the piston plate 201 abuts against the top of the inner wall of the liquid storage tank 303. At this time, the piston plate 201 is located above the position where the liquid inlet pipe 313 and the liquid storage tank 303 are connected. During this process, the piston plate 201 will balance the air pressure in its upper and lower areas through the vent hole 207 to avoid the generation of an air pressure difference. At the same time, the upward movement of the piston plate 201 will squeeze the baffle 101, causing the baffle 101 to gradually move upward to the inside of the groove 306 and pass through the rack 102 at the first The first gear 103 is driven upward inside the second chute 307 to rotate, so that the first tooth plate 104 drives the second tooth plate 105 to move downward inside the third chute 308, squeezes the first spring 110 and drives the transmission gear 106 meshing with the second tooth plate 105 to rotate, and the two transmission gears 106 drive the rotating disk 107 to rotate inside the main housing 301, so that the scraper 109 rotates inside the liquid outlet hole 304 to clean the inner wall of the liquid outlet hole 304, and at the same time, the motor 310 is started to make the rotating shaft 311 drive the stirring paddle 312 to rotate, so that the stirring paddle 312 cleans the inner wall of the liquid storage tank 303;

[0039] In addition, during the upward movement of the piston plate 201, the protrusion 205 will first abut against the fixed inclined block 214 on the third tooth plate 213. Because the friction coefficient of the inner wall of the fourth slide groove 309 is relatively large, the protrusion 205 will be moved to the inside of the receiving groove 202 by squeezing the inclined surface of the inclined block 214, and the second spring 206 will be squeezed by the first slide plate 204, and the vent hole 207 on the first slide plate 204 and the vent hole 207 on the piston plate 201 will be gradually misaligned to prevent the air in the upper and lower areas of the piston plate 201 from communicating. When the protrusion 205 is completely squeezed into the receiving groove 20 2, the inclined block 214 on the third tooth plate 213 will abut against the top of the piston plate 201, and the inclined block 214 drives the third tooth plate 213 to slide into the fourth slide groove 309 by squeezing the inclined surface, so that the second gear 212 rotates and the second slide plate 210 slides in the direction close to the piston plate 201 through the teeth 211, and finally the second slide plate 210 moves to the inside of the slide groove 203 and abuts against the protrusion 205. Because the friction coefficient of the inner wall of the fourth slide groove 309 is relatively large, the second slide plate 210 will not be reset under the elastic force of the second spring 206;

[0040] Then, a blood collection needle is used to collect an appropriate amount of blood sample from the patient. The blood sample is collected in a specific blood collection tube containing an anticoagulant. Large clots or impurities in the blood sample are removed by filtering or centrifugation. Then, the pretreated blood sample is injected into the liquid storage chamber 303 through the third tooth plate 213, wherein the height of the injected blood cannot exceed the height of the stirring paddle 312. The stirring paddle 312 continuously and slowly rotates to stir the blood sample to prevent the blood from being left to coagulate in the liquid storage chamber 303. Then, the main housing 301 is slid on the sliding frame 402 to align the liquid outlet head 305 with the blood carrier 404. At this time, the telescopic rod 208 is moved downward by the cylinder 209. When the piston plate 20 When the piston plate 201 moves to the position below the position where the liquid inlet pipe 313 and the liquid storage tank 303 are connected, the piston plate 201 will compress the space and air inside the liquid storage tank 303 downwards, and the blood in the liquid storage tank 303 is discharged from the liquid outlet head 305 to the corresponding blood carrying plate 404 through the liquid outlet hole 304 by air pressure. In this process, the piston plate 201 releases the squeezing of the baffle plate 101, and the second tooth plate 105 moves upward under the elastic force of the first spring 110, and drives the rotating disk 107 to rotate in the opposite direction through the transmission, so that the scraper plate 109 performs secondary cleaning on the inside of the liquid outlet hole 304, so as to prevent the blood from being left to solidify at the liquid outlet hole 304 and causing the liquid outlet hole 304 to be blocked, and the baffle plate 101 will also be reset under the action of the transmission;

[0041] The blood sampling can be effectively controlled by injecting blood through the cylinder 209. When the injection of one blood tray 404 is completed, the main housing 301 is slid to align the liquid outlet head 305 with the next blood tray 404 for injection. Finally, the blood sample is tested by the blood viscosity meter 401.

[0042] When the piston plate 201 moves downward to the position where it abuts against the top of the stirring paddle 312, the blood inside the liquid storage chamber 303 is completely discharged. At the same time, the bottom of the piston plate 201 will squeeze the inclined block 214 on the second slide plate 210. By squeezing the inclined surface, the inclined block 214 drives the second slide plate 210 to move to the inside of the fourth slide groove 309, releasing the abutment with the protrusion 205.
