Description

Technical Field

[0001] The utility model relates to the technical field of medical detection equipment, in particular to an automatic urine protein analyzer. Background Art

[0002] Urine testing is a routine test item in modern medical engineering and clinical medicine, and is one of the three major routine tests. Urine protein analyzer is a special instrument for clinical urine analysis combined with reagents made using dry chemical principles. The detection reagent changes color according to the content of several specific components in urine. The urine protein analyzer identifies the color change after the urine combines with the reagent, converts it into the component content, and outputs a test report.

[0003] When sampling samples for testing, the sampling personnel will generally place the samples in test tubes and paste an identification code on the test tubes that can identify the identity information of the person being tested. The test tubes will then be placed on test tube racks so that they can be transferred to the urine protein analyzer for testing.

[0004] Currently, the existing urine protein analyzers basically use manual code scanning to enable the device to obtain the identity information of the person being tested corresponding to the current test sample, and then manually place the test sample on the sampling mechanism, and then control the sampling mechanism to extract the test sample and send it to the device for testing; after the sampling mechanism extracts the test sample, the operator takes out the empty test tube from the device. It can be seen that the existing urine protein analyzers lack automated feeding and code scanning mechanisms, and manual operation will inevitably lead to relatively low test efficiency and increase the labor intensity of operators.

[0022] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0023] like Figure 1-20 As shown, an automatic urine protein analyzer includes a machine 1 and a controller 10. The machine 1 is provided with a feeding mechanism 3, a code scanning mechanism 4, a sample extraction mechanism 5, a reagent extraction mechanism 6, a reagent storage mechanism 7, a stirring mechanism 8, a detection mechanism 9 and a detection cleaning mechanism 2, which are electrically connected to the controller 10 respectively. The detection mechanism 9 is provided with a detection box 91. The sample extraction mechanism 5 is connected to the detection mechanism 9 and the feeding mechanism 3 respectively, and is used to extract the detection sample on the feeding mechanism 3 into the detection box 91. The reagent storage mechanism 7 is used to store the detection reagent. The reagent extraction mechanism 6 is connected to the reagent storage mechanism 7 and the detection mechanism 9 respectively, and is used to extract the detection reagent from the reagent storage mechanism 7 into the detection box 91. The stirring mechanism 8 is used to stir the detection sample and the detection reagent in the detection box 91 evenly. The detection mechanism 9 is used to detect the mixed solution in the detection box 91, and the detection cleaning mechanism 2 is used to clean the detection box 91. Before the test, the operator will place the test reagent into the reagent storage mechanism 7 in advance, and place the test tube 100 containing the urine sample on the test tube rack 200, and then place the test tube rack 200 on the feeding mechanism 3. During the test, the feeding mechanism 3 is first controlled to work, and the test tube rack 200 is transferred to the code scanning mechanism 4, and the code scanning mechanism 4 scans the test tube 100, and the acquired information is transmitted to the controller 10, so that the controller 10 can know the identity information of the person being tested corresponding to the urine sample at the current test position; then the sample extraction mechanism 5 is controlled to work to extract the urine sample from the test tube 100 and inject it into the test box 91; then the reagent extraction mechanism 6 is controlled to extract the test reagent from the reagent storage mechanism 7 and inject it into the test box 91; then the stirring mechanism 8 is controlled to work to stir the mixed solution in the test kit to stir it evenly; then the detection mechanism 9 is controlled to detect the mixed solution, and the detection result is transmitted to the controller 10, and the controller 10 outputs the detection result report. After the sample extraction mechanism 5 extracts the urine sample from the test tube 100 , the feeding mechanism 3 will send the empty test tube 100 out of the code scanning mechanism 4 , and transport other test tubes 100 containing urine samples on the test tube rack 200 to the code scanning mechanism 4 .

[0024] The feeding mechanism 3 includes a feeding component 31, a transport component 32 and a discharging component 33. The code scanning mechanism 4 is arranged at a position corresponding to the transport component 32, and is used to scan the QR code or bar code on the sample to be tested on the transport component 32. The transport component 32 is connected to the feeding component 31 and the discharging component 33 respectively, and is used to transfer the test tube rack 200 from the feeding component 31 to the discharging component 33. A discharge table 34 is arranged at a position corresponding to the feeding component 31 on the machine 1, and the feeding component 31 is connected to the discharge table 34, and is used to push the sample to be tested on the discharge table 34 to the feeding component 32. A discharging table 35 is arranged at a position corresponding to the discharging component 33 on the machine 1, and the feeding component 32 can push the test tube rack 200 to the discharging component 33, and the discharging component 33 is connected to the discharging table 35, and is used to push the sample on the feeding component 32 to the discharging table 35.

[0025] During operation, the operator first places the test tube rack 200 containing the test sample on the unloading table 34; then controls the feeding assembly 31 to work and pushes the test tube rack 200 as a whole onto the material transport assembly 32; then controls the material transport assembly 32 to work and transports the test tubes 100 on the test tube rack 200 to the code scanning mechanism 4 in sequence; controls the code scanning mechanism 4 to scan the barcode or QR code on the test tube 100, and transmits the scanning result to the controller 10, so that the controller 10 obtains the identity information of the person being tested corresponding to the sample at the current test position; then controls the sample extraction mechanism 5 to extract liquid from the test tube 100 on the material transport assembly 32. Take the test sample and transport it to the test box 91 for testing; then the material transport component 32 continues to work to transport the test tube 100 with the sample extracted to the corresponding position of the discharging component 33; when the entire test tube rack 200 is transported to the discharging component 33, the discharging component 33 is controlled to push the test tube rack 200 to the discharging platform 35; as the discharging component 33 continues to work, the test tube rack 200 coming out from the back will push the test tube rack 200 in front to slide on the discharging platform 35 until the entire discharging platform 35 is filled with test tube racks 200, and the operator then takes out all the test tube racks 200 to complete the automatic feeding and discharging process.

[0026] like Figure 3 , 4As shown, specifically, the feed assembly 31 includes a feed mounting frame 311, the feed mounting frame 311 is connected to the machine platform 1, a feed motor 312 and a feed driven wheel 313 are provided on the feed mounting frame 311, the feed driven wheel 313 is rotatably connected to the feed mounting frame 311, a feed driving wheel 314 is provided on the output end of the feed motor 312, a feed driving wheel 314 and the feed driven wheel 313 are sleeved with a feed transmission belt 315, a feed transmission belt 315 is provided on the feed transmission belt 315, and the feed pushing block 316 is connected to the unloading table 34. During processing, the test tube rack 200 containing the test sample is placed on the discharge table 34; the feed motor 312 is controlled to work, driving the feed driving wheel 314 to rotate, driving the feed transmission belt 315 to move, and the feed transmission belt 315 drives the feed push block 316 to move together, and the feed push block 316 will push the test tube rack 200 on the discharge table 34 to slide in the direction close to the material transport component 32, thereby transporting the test tube rack 200 to the material transport component 32, completing the feeding process of a test tube rack 200; thereafter, the feed motor 312 can be controlled to reverse and drive the feed push block 316 to reset to the initial position.

[0027] In order to limit and guide the movement direction of the feed push block 316, a feed guide rail 317 is provided on the feed mounting frame 311, and the feed push block 316 is slidably engaged with the feed guide rail 317. The movement direction of the feed push block 316 can be limited and guided by the limit of the feed guide rail 317, thereby improving the stability of the feed.

[0028] A first pusher block 318 is provided on the feed pusher block 316, and the first pusher block 318 passes through the unloading platform 34. The first pusher block 318 is hinged to the feed pusher block 316, and the first pusher block 318 can swing around the hinge point as the axis. A feed limit column 319 is provided on the feed pusher block 316, and the first pusher block 318 can abut against the feed limit column 319. By providing the first pusher block 318 and the feed limit column 319, when the feed motor 312 is reversed, the feed pusher block 316 will not drive the test tube rack 200 back to the initial position. During specific processing, after the operator places the test tube rack 200 on the unloading table 34, as the feeding motor 312 works regularly, the first pushing block 318 passes through one end of the unloading table 34 and abuts against the test tube rack 200 on the unloading table 34; under the thrust of the test tube rack 200, the first pushing block 318 swings along the hinged end until the first pushing block 318 abuts against the feeding limit column 319. Through the limiting of the feeding limit column 319, the first pushing block 318 can push the test tube rack 200 to slide on the unloading table 34 and push it to the corresponding position of the material transport component 32. When the feeding motor 312 rotates in the reverse direction, the end of the first pushing block 318 passing through the unloading platform 34 is pushed by the test tube rack 200 and will swing in the reverse direction along the hinge point, so that the end of the first pushing block 318 passing through the unloading platform 34 is separated from the test tube rack 200; therefore, during the reverse rotation of the feeding motor 312, the first pushing block 318 will not drive the test tube rack 200 to move. By providing the first pushing block 318 and the feeding limit column 319, the first pushing block 318 can realize a continuous feeding process during repeated movement on the unloading platform 34, thereby improving the feeding stability.

[0029] like Figure 5As shown, the material transport component 32 includes a material transport mounting frame 321, which is fixedly connected to the machine platform 1. A material transport motor 322 and a material transport driven wheel 323 are provided on the material transport mounting frame 321. The material transport driven wheel 323 is rotatably connected to the material transport mounting frame 321. A material transport driving wheel 324 is provided on the output end of the material transport motor 322. A material transport transmission belt 325 is sleeved on the material transport driving wheel 324 and the material transport driven wheel 323. A material transport pushing block 326 is provided on the material transport transmission belt 325. The material transport pushing block 326 is slidably connected to the material transport mounting frame 321, and the material transport pushing block 326 is connected to the material unloading table 34. A second pushing block 327 is provided on the material transport pushing block 326, and the second pushing block 327 can pass through the unloading platform 34. The second pushing block 327 is hinged to the material transport pushing block 326, and the second pushing block 327 can swing around the hinge point as the axis. A material transport limiting column 328 is provided on the material transport pushing block 326, and the second pushing block 327 can abut against the material transport limiting column 328. During operation, after the first pushing block 318 pushes the test tube rack 200 to the corresponding position of the transport component 32, the transport motor 322 is controlled to work, driving the transport driving wheel 324 to rotate, the transport driving wheel 324 drives the transport transmission belt 325 to move, the transport transmission belt 325 drives the transport pushing block 326 and the second pushing block 327 to move, and the second pushing block 327 will engage with the test tube rack 200, thereby driving the test tube rack 200 to move in the direction of the code scanning mechanism 4; then the code scanning mechanism 4 and the sample extraction mechanism 5 work, and when the sample extraction mechanism 5 extracts the sample from the test tube 100, the transport motor 322 continues to work to push the test tube rack 200 and the test tube 100 to the corresponding position of the discharge component 33.

[0030] like Figure 6 As shown, in this embodiment, 10 test tubes 100 are placed on the test tube rack 200, and a slot 201 is provided on the bottom surface of the test tube rack 200 at a position corresponding to each test tube 100; during processing, the second pusher block 327 can be inserted into the corresponding slot 201, thereby realizing the function of pushing the test tube rack 200 to move.

[0031] In the initial state, the second pusher block 327 is separated from the corresponding slot 201; the material transport motor 322 is controlled to work, driving the material transport pusher block 326 to drive the second pusher block 327 to move in the direction of the feed assembly 31. The second pusher block 327 will be connected to the test tube rack 200, and the directional thrust of the test tube rack 200 will push the second pusher block 327 to swing along the hinge point until the second pusher block 327 passes over the side wall of the test tube rack 200 and is inserted into the corresponding slot 201. Afterwards, the transport motor 322 is controlled to reverse, driving the second pushing block 327 to move in the direction of the code scanning mechanism 4. The side wall of the test tube rack 200 will push the second pushing block 327 to swing along the hinge point until the second pushing block 327 abuts against the feed limit column 319 and is limited by the feed limit column 319; therefore, as the transport motor 322 continues to reverse, it will drive the test tube rack 200 to move in the direction close to the code scanning mechanism 4, thereby achieving the purpose of moving the test tube rack 200 from the discharge table 34 to the code scanning mechanism 4.

[0032] It can be seen that when the transport motor 322 rotates forward, it will not drive the test tube rack 200 to move; when the transport motor 322 rotates reversely, the second push block 327 will drive the test tube rack 200 to move in the direction close to the code scanning mechanism 4 due to the limitation of the transport limit column 328; by controlling the repeated change of direction of the transport motor 322, the continuous transport processing process is realized.

[0033] In this embodiment, there are two second pusher blocks 327; during processing, the two second pusher blocks 327 can be respectively inserted into different slots 201 on the test tube rack 200. By providing two second pusher blocks 327, the test tube rack 200 can be stressed by two slots 201 at the same time when moving, thereby improving the stability of material transportation.

[0034] like Figure 7 As shown, the code scanning mechanism 4 includes a code scanning mounting frame 41, which is connected to the machine 1. The code scanning mounting frame 41 is provided with a scanning dock 42 connected to the controller 10, and the scanning dock 42 is used to scan the identification code on the test tube 100 on the material transport component 32. The material transport motor 322 can transport the test tubes 100 on the test tube rack 200 to the corresponding positions of the scanning dock 42, and can identify the two-dimensional code or bar code on the test tube 100 by controlling the scanning dock 42 to work; and transmit the corresponding information to the controller 10, so that the controller 10 obtains the corresponding tester identity information on the current test tube 100; and then controls the sample extraction mechanism 5 to extract the test sample from the test tube 100, and transports it to the detection mechanism 9 for detection.

[0035] In actual work, sampling personnel are unable to insert the test tube 100 into the test tube rack 200 in a uniform direction; therefore, the identification code on the test tube rack 200 often does not correspond to the position of the scanning terminal 42. This requires timely adjustment of the direction of the test tube 100 on the test tube rack 200 so that the QR code or bar code on the test tube 100 can be aligned with the scanning terminal 42.

[0036] like Figure 7 , 8 As shown, in this embodiment, the code scanning mechanism 4 also includes a calibration component for driving the test tube 100 to rotate on the test tube rack 200, the calibration component includes a calibration mounting frame 43, the calibration mounting frame 43 is connected to the machine 1, and a calibration drive component is provided on the calibration mounting frame 43, and the calibration drive component includes a calibration motor 44, and a calibration drive wheel 45 is provided on the output end of the calibration motor 44, and the calibration drive wheel 45 is rotatably connected to the calibration mounting frame 43, and the calibration drive wheel 45 can abut against the side wall of the test tube 100 on the material transport component 32. A rotatable calibration driven wheel 46 is provided on the code scanning mounting frame 41, and the calibration driven wheel 46 is arranged at a position corresponding to the calibration drive wheel 45, and the calibration driven wheel 46 can abut against the side of the test tube 100 away from the calibration drive wheel 45. During processing, after the material transport component 32 transports the corresponding test tube 100 to the corresponding position of the scanning dock 42; the calibration motor 44 is controlled to work and drive the calibration drive wheel 45 to rotate; at this time, both sides of the test tube 100 are limited by the calibration drive wheel 45 and the calibration driven wheel 46, so the test tube 100 will rotate with the calibration drive wheel 45, and the calibration driven wheel 46 will also rotate synchronously; in the process of rotation of the test tube 100, the QR code or barcode on the test tube 100 can be rotated to an angle corresponding to the scanning dock 42, so that the scanning dock 42 can recognize the QR code or barcode on the test tube 100, thereby realizing the function of scanning.

[0037] In order to avoid the interference of the calibration component with the movement of the material transport component 32, a driven wheel drive component is provided on the code scanning mounting frame 41, and the calibration driven wheel 46 is connected to the output end of the driven wheel drive component, and the driven wheel drive component can drive the calibration driven wheel 46 to move in the direction close to or away from the calibration drive wheel 45. In the initial state, when the material transport component 32 is working, the calibration driven wheel 46 and the test tube 100 are in a separated state, so the second pusher block 327 can push the test tube rack 200 to move in the direction of the code scanning mechanism 4; when the test tube 100 on the test tube rack 200 is aligned with the scanning dock 42, the material transport motor 322 stops working, and then controls the driven wheel drive component to work, driving the calibration driven wheel 46 to move in the direction close to the calibration drive wheel 45 until the calibration driven wheel 46 abuts against the side wall of the test tube 100; then the calibration motor 44 is controlled to work, so that the test tube 100 can rotate under the limit of the calibration drive wheel 45 and the calibration driven wheel 46, so as to achieve the purpose of adjusting the direction of the test tube 100. When the scanning dock 42 recognizes the QR code or barcode on the test tube 100, it controls the driven wheel driving assembly to drive the calibration driven wheel 46 to move away from the calibration driving wheel 45, so that the calibration driven wheel 46 is separated from the test tube 100, so that the material transport assembly 32 can drive the test tube rack 200 to move the test tube 100.

[0038] In this embodiment, the driven wheel driving assembly is a motor pulley structure; in other embodiments, the driven wheel driving assembly may also adopt a cylinder structure or an electric cylinder structure.

[0039] After the sample extraction mechanism 5 extracts the sample in the test tube 100, the transport motor 322 continues to work, and can push the test tube rack 200 and the test tube 100 onto the unloading platform 35 through the second pushing block 327, and then controls the unloading assembly 33 to push the test tube rack 200 out and arrange them neatly on the unloading platform 35.

[0040] like Fig. 9 , 10 As shown, the discharging assembly 33 includes a discharging mounting frame 331, on which a discharging motor 332 is provided, and on the output end of the discharging motor 332, a third pushing block 333 is provided, and the third pushing block 333 can extend into the discharging platform 35.

During stirring, the stirring drive motor 82 first drives the transmission assembly to move, and then drives the stirring drive wheel 83 to rotate. The stirring drive wheel 83 drives the linkage rod 86 to slide in the U-shaped groove 85. The stirring movable frame 84 and the stirring rod 818 are limited by the U-shaped groove 85, thereby driving the stirring movable frame 84 and the stirring rod 818 to first rise and then move forward, and then drop, so that the stirring rod 818 extends into the detection box 91; then the stirring motor 817 is controlled to work, and the stirring rod 818 is driven to rotate at a high speed to stir the urine sample and the detection reagent in the detection box 91.

[0076] In the initial state, the cleaning needle tube 27 is located directly above the detection box 91. When the detection box 91 needs to be cleaned, the cleaning motor 22 is controlled to work, the cleaning drive wheel 23 is driven to rotate, and the cleaning lifting rod 24 is driven to move downward, so that it is separated from the cleaning head mounting frame 26; then the cleaning head mounting frame 26 will slide downward along the cleaning lifting guide rail 25 under the action of its own gravity; the cleaning needle tube 27 will simultaneously descend until the cleaning needle tube 27 is inserted into the detection box 91, and then the detection box 91 is cleaned by the external cleaning liquid. After the cleaning is completed, the cleaning motor 22 is controlled to reverse, and the cleaning drive wheel 23 is driven to rotate in the opposite direction, driving the cleaning lifting rod 24 to move upward; at this time, the cleaning lifting rod 24 will push the cleaning head mounting frame 26 to move upward on the cleaning lifting guide rail 25; the cleaning needle tube 27 will rise synchronously until the cleaning needle tube 27 extends out of the detection box 91 and resets to the initial position.

[0077] Specifically, a cleaning lifting slider 28 is provided on the cleaning head mounting frame 26, and the cleaning lifting slider 28 is slidably engaged with the cleaning lifting guide rail 25. Through the cooperation of the cleaning lifting slider 28 and the cleaning lifting guide rail 25, the movement direction of the cleaning head mounting frame 26 can be limited and guided, thereby ensuring that the cleaning head mounting frame 26 can drive the cleaning needle tube 27 to be inserted into the detection box 91, thereby improving the transmission accuracy.

[0078] A cleaning push block 29 is provided on the cleaning head mounting frame 26, and a rotating bearing 210 is sleeved on the cleaning lifting rod 24. The rotating bearing 210 is connected to the cleaning push block 29, and the two are slidably matched. When the cleaning motor 22 and the cleaning lifting rod 24 rise, the rotating bearing 210 will slide on the cleaning push block 29, thereby pushing the cleaning head mounting frame 26 to rise; when the cleaning motor 22 rotates forward, the cleaning head mounting frame 26 falls due to its own gravity, which will push the rotating bearing 210 to rotate on the cleaning lifting rod 24. Through the cooperation of the rotating bearing 210 and the cleaning push block 29, the resistance of the cleaning head mounting frame 26 during the lifting and lowering movement can be reduced, thereby improving the stability and accuracy of the transmission.

[0079] A limit block 211 is provided at one end of the cleaning push block 29. When the cleaning lifting rod 24 pushes the cleaning head mounting frame 26 to rise to the initial position, or when the cleaning head mounting frame 26 descends to the limit position, the limit block 211 can abut against the rotating bearing 210. By providing the limit block 211, the movement stroke of the cleaning head mounting frame 26 can be limited, thereby improving the accuracy and stability of the transmission. In specific operation, when the limit block 211 abuts against the rotating bearing 210, the cleaning motor 22 will stop working immediately, thereby ensuring that the cleaning head mounting frame 26 can move to the preset position.

[0080] In order to improve the accuracy of control, a cleaning sensor 212 is provided on the cleaning mounting frame 21, and the cleaning sensor 212 is connected to the controller 10. Two cleaning induction paddles 213 are provided on the cleaning driving wheel 23, and the two cleaning induction paddles 213 can be connected to the cleaning sensor 212. In the initial state, one of the cleaning induction paddles 213 is connected to the cleaning sensor 212. When the cleaning motor 22 works to drive the cleaning driving wheel 23 to rotate, and then drives the cleaning lifting rod 24 to drop to the limit position, the other cleaning induction paddle 213 is connected to the cleaning sensor 212, and the cleaning sensor 212 feedbacks a signal to the controller 10 to control the cleaning motor 22 to stop working. At this time, the cleaning needle tube 27 just drops and inserts into the detection box 91. When the cleaning motor 22 reverses to drive the cleaning driving wheel 23 to rotate in the opposite direction, and then drives the cleaning lifting rod 24 to push the cleaning head mounting frame 26 to rise to the initial position, the cleaning induction paddle 213 at the initial position is just connected to the cleaning sensor 212, so that the feedback signal controls the cleaning motor 22 to stop working. Through the cooperation of the cleaning sensor 212 and the two cleaning sensing paddles 213, the movement stroke of the cleaning head mounting bracket 26 can be accurately controlled, thereby improving the transmission accuracy and processing stability.

[0081] The cleaning mechanism of the detection box 91 also includes an auxiliary descending mechanism, which is used to provide an auxiliary driving force during the free descent of the cleaning head mounting frame 26; thereby driving the cleaning head mounting frame 26 to move downward on the cleaning lifting guide rail 25. Specifically, the auxiliary descending mechanism includes an auxiliary spring 214, and the two ends of the auxiliary spring 214 are respectively connected to the cleaning head mounting frame 26 and the cleaning mounting frame 21. During operation, when the cleaning motor 22 reverses and drives the cleaning driving wheel 23 to rotate, and the cleaning head mounting frame 26 is pushed up by the cleaning lifting rod 24, the cleaning head mounting frame 26 rises and pulls up the auxiliary spring 214, thereby accumulating elastic potential energy. When the cleaning motor 22 rotates forward, the cleaning lifting rod 24 is separated from the limit of the cleaning head mounting frame 26, and the cleaning head mounting frame 26 is lowered by its own gravity. At the same time, the auxiliary spring 214 will also release elastic potential energy, thereby pulling the cleaning head mounting frame 26 to descend on the cleaning lifting guide rail 25. The auxiliary spring 214 can not only provide auxiliary driving force, but also eliminate the assembly gap between the cleaning push block 29 and the rotating bearing 210, thereby improving the compactness of the assembly; thereby reducing the sound generated during transmission and achieving the effect of noise reduction.

[0082] Working principle:

[0083] Before the test, the operator first places the test tube rack 200 containing the test sample on the discharge table 34, and places various test reagents in each reagent containing tank 73. During the test, the feed component 31 is first controlled to work, and the test tube rack 200 is pushed onto the transport component 32 as a whole; the transport component 32 is then controlled to work, and the test tubes 100 on the test tube rack 200 are sequentially transported to the code scanning mechanism 4; the code scanning mechanism 4 is controlled to scan the barcode or QR code on the test tube 100, and the scanning result is transmitted to the controller 10, so that the controller 10 obtains the identity information of the person being tested corresponding to the sample at the current test position; then the first liquid extraction drive component 52 is controlled to work, and the sample sampling needle 53 is driven to extend into the test tube 100 to extract the urine sample, and the urine sample is transported and injected into the test box 91. At the same time, the storage drive assembly is controlled to work, driving the reagent storage tray 72 to rotate, so that each reagent holding groove 73 is aligned with the reagent sampling needle 63; then the second liquid extraction drive assembly 62 is controlled to work, driving the reagent sampling needle 63 to extend into the reagent holding groove 73 to extract the detection reagent, and transport it into the detection box 91.

[0084] Then, the stirring drive motor 82 is controlled to work, and the stirring rod 818 is driven to extend into the detection box 91 to stir the urine sample and the detection reagent evenly; then, the heating plate 96 is controlled to heat the mixed solution in the detection box 91, and the temperature of the mixed solution is heated to the same as the human body temperature. Then, the detection drive motor 98 is controlled to work, and the detection box 91 containing the mixed solution is driven to move to the position corresponding to the optical detection head 93, and then the optical detection head 93 is controlled to detect the mixed solution in the detection box 91, and the detection operation of the sample urine is completed. After the detection is completed, the cleaning motor 22 is controlled to work, and the cleaning needle 27 is driven to be inserted into the detection box 91, and then the detection box 91 is cleaned by an external cleaning liquid. After the cleaning is completed, the cleaning motor 22 is controlled to reverse, and the cleaning needle 27 is driven to extend out of the detection box 91 to reset to the initial position.

[0085] After the urine sample in the test tube 100 is extracted, the transport component 32 continues to work to transport the test tube 100 with the sample extracted to the corresponding position of the discharging component 33; when the entire test tube rack 200 is transported to the discharging component 33, the discharging component 33 is controlled to push the test tube rack 200 to the discharging platform 35; as the discharging component 33 continues to work, the test tube rack 200 coming out from the back will push the test tube rack 200 in front to slide on the discharging platform 35 until the entire discharging platform 35 is filled with test tube racks 200, and the operator then takes out all the test tube racks 200, thereby completing a round of testing process.
