Description

TECHNICAL FIELD

[0001] The present application relates to the field of immunoblot detection technology, in particular to an unattended full-automatic immunoblot detection system and method. BACKGROUND

[0002] The immunoblot analyzer, also known as Western Blot analyzer, is a high-throughput laboratory analysis equipment that uses immunoblot technology to complete the whole process of sample preparation, immunoreaction, detection and result analysis.

[0003] The principle of the immunoblot analyzer is as follows:

[0004] Sample preparation: extract the protein of the sample to be tested and perform lysis and protein separation.

[0005] Electrophoretic separation: the separated proteins are subjected to electrophoretic separation on a gel according to their molecular weight, forming a protein spectrum in the form of bands.

[0006] Membrane transfer: the proteins on the gel are transferred to a nitrocellulose membrane (NC membrane) or a PVDF membrane, forming protein bands.

[0007] Blocking: blocking the non-specific binding sites on the membrane to prevent the antibody from binding to the non-target protein.

[0008] Antibody incubation: incubating the labeled specific antibody with the target protein on the membrane to allow the antibody to bind to the target protein.

[0009] Washing: washing away the unbound antibody to improve the signal intensity.

[0010] Color development: according to the type of labeled antibody, using the corresponding color developing reagent for color development, so that the site where the antibody binds to the target protein shows color.

[0011] Detection signal: scanning and analyzing the colored membrane by the instrument to obtain the signal intensity of the target protein.

[0012] Result analysis: the system automatically analyzes the signal intensity and compares it with the standard to obtain the content or activity of the target protein.

[0013] However, the existing immunoblot detection methods can be divided into manual detection and instrument detection. The manual detection method requires the replacement of different reagents, frequent operation, which increases the work intensity of the experimenter and wastes time, and the manual operation is complicated and complex, the contact with potentially infectious materials is more, and the detection safety is poor.

[0034] An unattended fully automatic immunoblotting detection method, which is applicable to the above-mentioned unattended fully automatic immunoblotting detection system; the method comprises:

[0035] S1: First, the staff places the sample to be tested into the sample pool, the sample to be tested into the sample well on the sample tray, then places the reagent into the reagent pool, and the reagent solution box into the reagent kit placement slot; finally, the incubation dish is placed into the reaction dish placement slot on the incubation tray;

[0036] S2: Based on the above S1, the automatic immunoblotting detector is then started. After the instrument is started, the No. 1 rotating column drives the No. 1 limiting column and the sample adding plate to rotate, so that the sample adding needle under the sample adding plate is located under its corresponding cleaning tank. During the process, the sample adding needle moves downward into the inside of the cleaning tank, and then the nozzle sprays the cleaning liquid to clean the sample adding needle;

[0037] S3: Based on the above S2, after cleaning, the sample needle moves out of the cleaning tank; then the No. 1 rotating column rotates, and after the sample needle is moved to the top of the sample pool, the sample needle moves downward to extract the sample to be tested inside the sample tube. Then, the No. 1 rotating column rotates to rotate the sample needle to the top of the reaction pool, and then the sample needle injects the sample to be tested into the incubation dish; then the incubation dish inside the reaction pool rotates;

[0038] S4: During the above S3 process, the telescopic rod on the second rotating column retracts downward, sending the reagent needle into the cleaning tank for cleaning. After the reagent needle is cleaned, the second rotating column moves the reagent needle to the top of the reagent pool, and then the reagent needle extracts the reagent solution in the reagent kit; after the reagent needle is extracted, the reagent needle injects the reagent solution into the incubation dish;

[0039] S5: Based on the above S4, the incubation plate is then rotated, and the sample to be tested in the incubation dish is mixed with the reagent solution during the process. When the incubation plate first passes the position of the No. 3 rotating column and the waste liquid recovery needle during the rotation, the incubation plate does not stop; and when the incubation dish containing the reagent solution and the sample to be tested rotates to the lower end of the curved plate, the ultrasonic vibrator vibrates the reagent solution and the sample to be tested inside the incubation dish, so that the reagent solution and the sample to be tested are fully mixed;

[0040] S6: Based on the above S5, the incubation tray continues to rotate until the incubation tray drives the incubation dish to rotate to the position of the third rotating column for the second time. The third rotating column drives the waste liquid recovery needle to move to the top of the incubation dish through the waste liquid recovery plate. Then the waste liquid recovery needle extracts the solution inside the incubation dish. After collection, the waste liquid recovery needle injects the extracted solution into the waste liquid recovery hole, and the solution flows into the interior of the waste liquid recovery box through the waste liquid recovery hole;

[0041] S7: Based on the above S6, the incubation plate continues to rotate until the incubation dish containing the mixed solution of the extracted reagent liquid and the test liquid moves to the bottom of the curved plate for the second time. The interpretation and analysis module at the lower end of the curved plate takes an image of the incubation dish, thereby realizing fully automatic detection, improving detection results, and avoiding waste of manpower.

[0042] The beneficial effects of the present invention are as follows:

[0043] After the sample needle is cleaned, part of the cleaning liquid will remain on the surface of the sample needle. At this time, since the sample needle is cleaned, the sample needle needs to move upward to reset. During the upward movement of the sample needle, the mounting tube and the cleaning plate are in a stationary state, so the sample needle, the mounting tube and the cleaning plate are in a relative motion state, so that the sample needle moves upward in the through hole in the middle of the cleaning plate. During the process, the inner wall of the through hole is in close contact with the outer side of the sample needle, so that the cleaning plate scrapes off the cleaning liquid on the surface of the sample needle, avoiding the problem of cross infection when sampling the sample to be tested, thereby improving the accuracy of the test.

[0070] The specific work flow is as follows;

[0071] When using the test kit, the staff first places the sample to be tested into the sample pool 11, and then places the sample to be tested into the sample well on the sample tray. Then, the reagent is placed into the reagent pool 12, and the reagent liquid box is placed into the reagent kit placement slot 122; finally, the incubation dish is placed into the reaction dish placement slot 132 on the incubation tray 131;

[0072] Then start the automatic immunoblotting detector. After the instrument is started, the No. 1 rotating column 14, the No. 2 rotating column 15 and the No. 3 rotating column 16 on the instrument body 1 can rotate on the instrument body 1. The rotation method is driven by the stepper motor set under the three. When the sample to be tested is tested, the No. 1 rotating column 14 rotates first, and the No. 1 rotating column 14 drives the No. 1 limiting column 141 and the sample adding plate 142 to rotate, so that the sample adding needle 143 under the sample adding plate 142 is located under its corresponding cleaning tank 17. Then the telescopic rod on the No. 1 rotating column 14 is retracted, driving the sample adding plate 14 2 moves downward, and during the process, the sample adding needle 143 moves downward to the inside of the cleaning tank 17, and then the nozzle 172 inside the cleaning tank 17 is started, and the nozzle 172 pumps the cleaning liquid inside the cleaning liquid storage box 171 into the inside of the nozzle 172 through the pump provided on the instrument body 1, and then the nozzle 172 sprays the cleaning liquid to clean the sample adding needle 143. After cleaning, the telescopic rod on the No. 1 rotating column 14 extends, driving the sample adding plate 142 and the sample adding needle 143 to move upward, and the sample adding needle 143 moves out of the cleaning tank 17; then the No. 1 rotating column 14 rotates, driving the No. 1 limiting column 141 and the sample adding needle 143 to move upward, and the sample adding needle 143 moves out of the cleaning tank 17; The sample plate 142 and the sample adding needle 143 rotate synchronously until the sample adding needle 143 is located just above the sample pool. At this time, the sample plate inside the sample pool rotates until the sample tube to be tested rotates to just below the sample adding needle 143. The telescopic rod on the No. 1 rotating column 14 contracts, driving the sample adding plate 142 to move downward on the No. 1 limiting column 141. During this process, the sample adding needle 143 moves downward until the sample adding needle 143 moves into the inside of the sample tube to be tested. Then the sample adding needle 143 extracts the sample to be tested inside the sample tube (the extraction method is the pneumatic extraction in the prior art, which will not be detailed here). (It will be repeated) after the sampling is completed, the telescopic rod on the No. 1 rotating column 14 drives the sample adding needle 143 to move upward; then the No. 1 rotating column 14 rotates to rotate the sample adding needle 143 to the top of the reaction pool 13, and then the telescopic rod on the No. 1 rotating column 14 contracts downward to move the sample adding needle 143 to the incubation dish on the incubation disk 131, and then the sample adding needle 143 injects the sample to be tested into the incubation dish; then the incubation disk 131 inside the reaction pool 13 rotates, and the rotation of the incubation disk 131 is driven by the driving motor provided at the lower end of the incubation disk 131. During the rotation of the incubation disk 131;

[0073] When the second rotating column 15 rotates, the second rotating column 15 drives the second limiting column 151, the reagent disk 121 and the reagent needle 153 to the top of the cleaning groove 17 corresponding to the rotating column, the telescopic rod on the second rotating column 15 contracts downward, and the reagent needle 153 is sent into the cleaning groove 17. Then the nozzle 172 in the cleaning groove 17 corresponding to the reagent needle 153 cleans the reagent needle 153 (the cleaning method and cleaning principle of the reagent needle 153 are the same as the cleaning method of the above-mentioned sample addition needle 143); after the cleaning of the reagent needle 153 is completed, the telescopic rod on the second rotating column 15 extends to drive the reagent needle 153 to reset. After the reagent needle 153 is reset, the second rotating column 15 drives it to rotate until the reagent needle 153 moves to the top of the reagent pool 12, and then the reagent disk 121 inside the reagent pool 12 rotates. During the rotation of the reagent disk 121, the refrigeration device arranged inside the reagent pool 12 cools the reagent liquid. , so that the temperature of the reagent solution is maintained between 0-6°C. After the required reagent liquid box rotates to the bottom of the reagent needle 153, the telescopic rod on the No. 2 rotating column 15 contracts to send the reagent needle 153 into the reagent liquid box, and then the reagent needle 153 extracts the reagent liquid in the reagent kit (the extraction method is the same as the extraction method of the sample injection needle 143); after the reagent needle 153 is extracted, the telescopic rod on the No. 2 rotating column 15 extends and resets, driving the reagent needle 153 to reset, and then the No. 2 rotating column 15 rotates to rotate the reagent needle 153 to the top of the reaction pool 13; in this process, the incubation disk 131 rotates until the incubation dish into which the sample injection needle 143 is injected into the sample to be tested rotates to the bottom of the reagent needle 153, the telescopic rod on the No. 2 rotating column drives the reagent needle 153 to move downward, and sends the reagent needle 153 to the top of the incubation dish, and then the reagent needle 153 injects the reagent liquid into the incubation dish;

[0074] Then the incubation tray 131 rotates, and during the rotation, the heating device provided inside the reaction pool 13 heats the incubation dish (the heating device is a prior art and will not be described in detail here); during the rotation of the incubation tray 131, the sample to be tested in the incubation dish is mixed with the reagent solution, and when the incubation tray 131 rotates and passes the position of the third rotating column 16 and the waste liquid recovery needle 162 for the first time, the incubation tray 131 does not stop; and when the incubation dish containing the reagent solution and the sample to be tested rotates to the lower end of the arc plate 18, the arc plate The telescopic rod at the lower end of 18 drives the arc plate 18 to move downward, and the ultrasonic vibrator 181 at the lower end of the arc plate 18 vibrates the reagent liquid and the sample to be tested inside the incubation dish, so that the reagent liquid and the sample to be tested are fully mixed, and then the incubation plate 131 continues to rotate until the incubation dish 131 drives the incubation dish to rotate to the position of the third rotating column 16 for the second time, and the third rotating column 16 drives the waste liquid recovery needle 162 to move to the top of the incubation dish through the waste liquid recovery plate 161, and then the telescopic rod above the third rotating column 16 is retracted. The waste liquid recovery needle 162 is retracted to the inside of the incubation dish, and then the waste liquid recovery needle 162 extracts the solution inside the incubation dish. After collection, the telescopic rod on the No. 3 rotating column 16 is extended, and then the No. 3 rotating column 16 rotates the waste liquid recovery needle 162 to the top of the waste liquid recovery hole 163, and then the telescopic rod on the No. 3 rotating column 16 sends the waste liquid recovery needle 162 into the waste liquid recovery hole 163, and then the solution extracted by the waste liquid recovery needle 162 is injected into the waste liquid recovery hole 163, and the solution passes through the waste liquid recovery hole 163 flows into the interior of the waste liquid recovery box 164, and then the incubation disk 131 continues to rotate until the incubation dish containing the mixed solution of the reagent liquid and the test liquid moves to the bottom of the curved plate 18 for the second time. The interpretation and analysis module 182 at the lower end of the curved plate 18 takes an image of the incubation dish (the interpretation and analysis module 182 is a camera that analyzes the captured image and outputs the result, and transmits the output result to the display on the instrument body 1); thereby achieving fully automatic detection, improving detection effect, and avoiding waste of manpower;

[0075] In this process, the sample injection needle 143 and the reagent needle 153 are used to extract the sample or reagent solution to be tested; through the arrangement of the mounting tube 21 and the mounting plate 2; the following effects are achieved; since the reagent needle 153 and the mounting tube 21 installed outside the sample injection needle 143 have the same effect and principle, the sample injection needle 143 is taken as an example here;

[0076] The mounting plate 2 is provided at the upper end of the No. 1 limiting post 141, and the mounting plate 2 is located just above the sample adding plate 142, and the mounting plate 2 and the sample adding plate 142 are in a state of synchronous movement; in the process of the sample adding needle 143 sampling the sample to be tested inside the sample pool, when the sample adding needle 143 moves to the top of the sample pool, the telescopic rod on the No. 1 rotating post 14 contracts, and the sample adding moves downward. In the process, the sample adding plate 142 moves downward on the No. 1 limiting post 141, but the mounting plate 2 and the No. 1 limiting post 141 are fixedly connected, so the mounting plate 2 will not move downward, and the mounting tube 21 will not move downward. Since the lower end of the mounting tube 21 passes through the sample adding plate 142 and is slidably connected to the sample adding plate 142, the side wall of the mounting tube 21 is provided with a slide groove 22, so that the partial area between the sample adding needle 143 and the sample adding plate 142 is slidably connected to the sliding groove. The interior of the slot 22 prevents the sample adding needle 143 from being filled in the air, and during the downward movement of the sample adding needle 143 and the sample adding plate 142, the area between the sample adding needle 143 and the sample adding plate 142 moves downward inside the slide slot 22. During the process, the lower end of the sample adding needle 143 will gradually extend out of the mounting tube 21, allowing the sample adding needle 143 to extract the sample to be tested; after the extraction is completed, the sample adding needle 143 rises, and the sample adding plate 142 rises on the No. 1 limit post 141, but the mounting tube 21 does not move, allowing the sample adding needle 143 to enter the interior of the mounting tube 21. Since the sample adding needle 143 is in the non-working state, the sample adding needle 143 is at the temporal part of the mounting tube 21, so that the mounting tube 21 protects the sample adding needle 143 and avoids the problem of people accidentally touching the sample adding needle 143; thereby improving the safety of the sample adding needle 143 and avoiding its damage.

[0077] Example 2:

[0078] like Figures 2 to 11 As shown; a cleaning plate 23 with a disc structure is provided on the inner side of the lower end of the mounting tube 21, and a through hole 231 is provided in the middle of the cleaning plate 23; a chamfer 232 is provided at the opening of the upper end of the through hole 231; a leakage hole 24 is provided in the middle of the cleaning plate 23, one end of the leakage hole 24 is located at the chamfer 232 of the through hole 231, and the other end is located at the lower end of the cleaning plate 23, and the leakage hole 24 is arranged to be inclined downward, and the lower end of the leakage hole 24 is away from the lower end opening of the through hole 231;

[0079] The sample injection needle 143 and the reagent needle 153 both pass through the corresponding through hole 231 in the middle of the cleaning plate 23;

[0080] The specific work flow is as follows;

[0081] A cleaning plate 23 in disc structure is arranged inside the lower end of the mounting pipe 21, and a through hole 231 is formed in the middle part of the cleaning plate 23, so that the sample adding needle 143 and the reagent needle 153 extend from inside the corresponding through hole 231; on the basis of the above embodiment, after the sample adding needle 143 is cleaned, part of the cleaning liquid will remain on the surface of the sample adding needle 143, at this time, after the sample adding needle 143 is cleaned, the sample adding needle 143 needs to move upward to reset, at this time, the mounting pipe 21 and the cleaning plate 23 are in a static state during the upward movement of the sample adding needle 143, so that the sample adding needle 143 is in a relative motion state with the mounting pipe 21 and the cleaning plate 23, and moves upward in the through hole 231 in the middle part of the cleaning plate 23, and the inner wall of the through hole 231 is in close contact with the outer side of the sample adding needle 143 during the process, so as to realize the cleaning of the cleaning liquid on the surface of the sample adding needle 143 by the cleaning plate 23, avoid cross infection of the sample adding needle 143 to the sample to be tested, and further improve the detection accuracy;

[0082] And a chamfer 232 is formed in the upper end of the through hole 231, and a liquid leakage hole 24 is formed in the inside of the cleaning plate 23, and when the sample adding needle 143 contacts the through hole 231, an annular groove is formed between the sample adding needle 143 and the chamfer 232 on the through hole 231, since the sample adding needle 143 is in a frequent working state, if the liquid on the surface of the sample adding needle 143 is not completely cleaned during the upward movement of the sample adding needle 143, the liquid will gather at the chamfer 232 when the sample adding needle 143 moves upward above the cleaning plate 23, and then the liquid can leak out of the cleaning plate 23 through the liquid leakage hole 24, thereby improving the cleaning effect of the sample adding needle 143 and further avoiding cross infection and improving the detection effect.

[0083] Embodiment three:

[0084] As shown in Figures 2 to 10 The upper end of the cleaning plate 23 is provided with a plurality of air cylinders 25, the inside of the air cylinder 25 is connected with a sliding rod 26 in a sliding manner, and the sliding rod 26 is connected with the inner wall of the air cylinder 25 in a sealed sliding manner;

[0085] The inside of the cleaning plate 23 is provided with an annular groove 233, the annular groove 233 is communicated with the air outlet of the air cylinder 25, the inside of the cleaning plate 23 is provided with a plurality of air vent grooves 234, the upper end of the air vent groove 234 is communicated with the annular groove 233, and the lower end of the air vent groove 234 is located at the lower end of the cleaning plate 23; the air vent groove 234 is inclined towards the middle part of the cleaning plate 23;

[0086] The annular groove 233 is not connected to the leakage hole 24. A connecting hole 235 is provided between the vent groove 234 and the leakage hole 24. The connecting hole 235 connects the vent groove 234 and the leakage hole 24. The connecting hole 235 is inclined toward the vent groove 234.

[0087] The specific work flow is as follows;

[0088] A plurality of cylinders 25 are provided at the upper end of the cleaning plate 23. The interior of the cylinder 25 is slidably connected to the connecting rod, and the connecting rod is sealed and slidably connected to the inner wall of the cylinder 25. When the sample needle 143 is cleaned, the sample needle 143 moves upward, and the cleaning plate 23 and the through hole 231 complete the initial cleaning of its surface. When the sample needle 143 takes a sample to be tested, the sample needle 143 moves downward, and the sample plate 142 moves downward during the process. The mounting tube 21 and the cleaning plate 23 remain stationary. The portion of the sample plate 142 located inside the mounting tube 21 pushes the upper end of the slide rod 26, causing the slide rod 26 to move downward in the cylinder 25, squeezing the gas in the cylinder 25. At this time, the gas in the cylinder 25 The gas will enter the annular groove 233 provided in the cleaning plate 23. Since the cleaning plate 23 also has a ventilation groove 234, which is connected to the annular groove 233, the gas in the annular groove 233 will enter the ventilation groove 234 and be ejected from the ventilation groove 234. Since the ventilation groove 234 is inclined toward the middle of the cleaning plate 23, and the sample adding needle 143 passes through the middle of the cleaning plate 23, when the sample adding needle 143 moves downward to take a sample, the gas ejected from the ventilation groove 234 will blow on the surface of the sample adding needle 143, thereby preventing the surface of the sample adding needle 143 from being wet and preventing dust from forming on the surface of the sample adding needle 143, which would affect the detection accuracy.

[0089] The annular groove 233 is not connected to the leakage hole 24, so that the gas inside the annular groove 233 will not enter the leakage hole 24, and the ventilation groove 234 is connected to the leakage hole 24 through the connecting hole 235 provided in the cleaning plate 23, and the connecting hole 235 is arranged to be inclined downward, and the connecting hole 235 is inclined toward the ventilation groove 234. When the gas inside the annular groove 233 is ejected from the ventilation groove 234, the gas moves inside the ventilation groove 234 and passes through the connecting hole 235. Due to the flow of gas, the gas flow rate inside the ventilation groove 234 is large, which will attract the gas inside the leakage hole 24, so that the gas inside the leakage hole 24 enters the ventilation groove 234, thereby driving the gas circulation inside the leakage hole 24, avoiding the leakage hole 24 from being in a humid state for a long time and the air from being stagnant, thereby avoiding the problem of bacteria easily breeding inside the leakage hole 24, further improving the cleaning effect of the sampling needle 143, and thus the detection accuracy.

[0090] Example 4:

[0091] like Figures 1 to 11 As shown; an annular plate 27 is provided at the upper end of the plurality of slide rods 26, the inner wall of the mounting tube 21 is provided with a spiral groove 28, the outer side of the annular plate 27 is provided with a slider, the slider is slidably connected to the interior of the spiral groove 28;

[0092] The upper end of the annular plate 27 is provided with a ball 271;

[0093] A cylinder 29 is provided between the plurality of cylinders 25 , and an ultraviolet light strip is provided on the inner wall of the cylinder 29 , and the ultraviolet light strip wraps the corresponding sample injection needle 143 and reagent needle 153 ;

[0094] The specific work flow is as follows;

[0095] An annular plate 27 is provided at the upper end of the slide bar 26, and a spiral groove 28 is provided on the inner wall of the mounting tube 21, and a slider is provided on the outer side of the annular plate 27, and the slider is slidably connected to the inside of the spiral groove 28; so that during the downward movement of the sample adding needle 143, the end of the sample adding plate 142 located inside the mounting tube 21 presses the annular plate 27, and the annular plate 27 pushes the slide bar 26 to move downward inside the cylinder 25. During the downward movement of the annular plate 27, since the outer side of the annular plate 27 is slidably connected to the inside of the spiral groove 28 through the slider, The slider is guided by the spiral groove 28 to rotate, thereby driving the annular plate 27 to rotate. The annular plate 27 drives the cylinder 25 to rotate through the slide rod 26. The cylinder 25 is fixedly connected to the cleaning plate 23, and the cleaning plate 23 is slidably connected to the inner wall of the mounting tube 21. Therefore, the cleaning plate 23 rotates with the cleaning plate 23. When the cleaning plate 23 rotates, it rotates and wipes the surface of the sample needle 143, thereby improving the cleaning effect of the surface of the sample needle 143, further avoiding the problem of cross infection of the sample needle 143, and further improving the detection accuracy.

[0096] A ball 271 is provided on the annular plate 27 to reduce the friction between the annular plate 27 and the sample adding plate 142 during rotation, thereby reducing the resistance to annular rotation and improving the service life. A cylinder 29 is provided between the multiple cylinders 25, and an ultraviolet light strip is provided on the inner wall of the cylinder 29, so that the ultraviolet light can wrap around the sample adding needle 143 and the reagent needle 153, so that in the process of cleaning the surface of the sample adding needle 143 or the reagent needle 153, the ultraviolet light strip is always irradiating and sterilizing the surface of the sample adding needle 143 or the reagent needle 153, further improving the cleaning effect of the surface of the sample adding needle 143 and the reagent needle 153, thereby avoiding cross contamination and improving the detection accuracy.

[0100] S2: Based on the above S1, the automatic immunoblotting detector is then started. After the instrument is started, the first rotating column 14 drives the first limiting column 141 and the sample loading plate 142 to rotate, so that the sample loading needle 143 below the sample loading plate 142 is located below its corresponding cleaning tank 17. During this process, the sample loading needle 143 moves downward into the inside of the cleaning tank 17, and then the nozzle 172 sprays the cleaning liquid to clean the sample loading needle 143;

[0101] S3: Based on the above S2, after cleaning, the sample needle 143 moves out of the cleaning tank 17; then the No. 1 rotating column 14 rotates, and after the sample needle 143 is moved to just above the sample pool, the sample needle 143 moves downward to extract the sample to be tested from the sample tube. Then, the No. 1 rotating column 14 rotates to rotate the sample needle 143 to above the reaction pool 13, and then the sample needle 143 injects the sample to be tested into the incubation dish; then, the incubation disk 131 inside the reaction pool 13 rotates;

[0102] S4: During the above S3 process, the telescopic rod on the second rotating column 15 is retracted downward, and the reagent needle 153 is sent to the cleaning tank 17 for cleaning. After the reagent needle 153 is cleaned, the second rotating column 15 moves the reagent needle 153 to the top of the reagent pool 12, and then the reagent needle 153 extracts the reagent solution in the reagent kit; after the reagent needle 153 completes the extraction, the reagent needle 153 injects the reagent solution into the incubation dish;

[0103] S5: Based on the above S4, the incubation tray 131 rotates, and the sample to be tested in the incubation dish is mixed with the reagent solution during the process. When the incubation tray 131 first passes the position of the third rotating column 16 and the waste liquid recovery needle 162 during the rotation, the incubation tray 131 does not stop; and when the incubation dish containing the reagent solution and the sample to be tested rotates to the lower end of the curved plate 18, the ultrasonic vibrator 181 vibrates the reagent solution and the sample to be tested inside the incubation dish, so that the reagent solution and the sample to be tested are fully mixed;

[0104] S6: Based on the above S5, the incubation tray 131 continues to rotate until the incubation tray 131 drives the incubation dish to rotate twice to the position of the third rotating column 16. The third rotating column 16 drives the waste liquid recovery needle 162 to move above the incubation dish through the waste liquid recovery plate 161. Then the waste liquid recovery needle 162 extracts the solution inside the incubation dish. After the solution is collected, the waste liquid recovery needle 162 injects the extracted solution into the waste liquid recovery hole 163. The solution flows into the waste liquid recovery box 164 through the waste liquid recovery hole 163.
