[0057] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0058] The medical testing sampling device disclosed in this invention is mainly used in situations where, during sample container replacement, urine may come into contact with the inner wall of the first urine sampling container, causing urine to splash and subsequently enter the middle sample container, thus contaminating the urine sample taken from the middle section.

[0060] Sampling base 1, two guide rails 6 are provided on sampling base 1, a sewage frame 7 is also provided on sampling base 1, and a sewage pipe 11 is provided on sewage frame 7.
[0061] Four mounting parts 9 are respectively set on the outer walls of both sides of the sampling base 1, and the same linear screw 8 is set on every two mounting parts 9;
[0062] Two stepper motors 2 are respectively mounted on two mounting parts 9, and the output shafts of the two stepper motors 2 are respectively connected to one end of two linear lead screws 8 through couplings;
[0063] The movable platform 3 is mounted on two guide rails 6 and two linear screws 8, and the movable platform 3 is equipped with an installation frame 10.
[0064] Sampling anti-contamination unit 5 is mounted on the mounting frame 10. Sampling anti-contamination unit 5 includes three collection guides 501 and splash baffles 508. Each of the three collection guides 501 is equipped with a splash-proof mesh plate 505.
[0065] The sampling sealing module 4 is set on the movable platform 3. The sampling sealing module 4 includes a rotating frame 407 and three fixed suction cups 417.
[0066] Reference Figures 1-6 In a preferred embodiment, the sampling and anti-fouling unit 5 further includes:
[0067] Three shaft members 514 are all mounted on the mounting frame 10. One end of each shaft member 514 is provided with a placement frame 502. Three collection guides 501 are respectively mounted on the three placement frames 502. Each of the three collection guides 501 is provided with a connecting pipe port 509.
[0068] Three servo motors 504 are mounted on the mounting frame 10. The output shafts of the three servo motors 504 are connected to the other ends of the three shaft members 514 respectively through couplings.
[0069] Three mounting rods 515 are respectively mounted on three placement frames 502.
[0070] In this invention, the sampling and anti-fouling unit 5 further includes:
[0071] Three fixing plates 512 are respectively set on three mounting rods 515. Each of the three fixing plates 512 is provided with a handle 513. The outer wall of one side of the three fixing plates 512 is in contact with the inner wall of one side of the three collecting guide buckets 501.
[0072] Multiple torsion springs 516 are respectively disposed on the outside of three mounting rods 515. One end of each torsion spring 516 is fixedly connected to the outer walls of the two sides of the three fixing plates 512, and the other end of each torsion spring 516 is fixedly connected to the inner walls of the two sides of the three placement frames 502.
[0073] In this invention, the sampling and anti-fouling unit 5 further includes:
[0074] Two fixed brackets 503 are provided on the mounting frame 10, and the same connecting shaft 517 is provided on the two fixed brackets 503.
[0075] The mounting shaft 519 is mounted on one of the placement frames 502. Both ends of the mounting shaft 519 and the connecting shaft 517 are equipped with a linkage wheel 510, and the two linkage wheels 510 are equipped with the same linkage belt 511.
[0076] In this invention, the sampling and anti-fouling unit 5 further includes:
[0077] Two take-up rollers 518 are mounted on a connecting shaft 517. Each of the two take-up rollers 518 is equipped with a connecting cable 507. A splash baffle 508 is mounted on one end of the two connecting cables 507.
[0078] Two guide wheels 506 are respectively mounted on two fixed brackets 503, and the outer walls of the two connecting cables 507 are in contact with the inner walls of the two guide wheels 506 respectively.
[0079] Specifically, when the collection guide bucket 501 is installed, the handle 513 drives the fixing plate 512 to rotate, causing the torsion spring 516 to deform. Then, the collection guide bucket 501 is placed on the placement frame 502, and the handle 513 is released so that the torsion spring 516 returns to its original state, and the fixing plate 512 clamps and fixes the collection guide bucket 501.
[0080] During sampling, servo motor 504 operates, driving shaft 514 to rotate. This shaft 504, in turn, drives placement frame 502 and collection guide 501 to rotate until collection guide 501 and its splash guard 505 move to the urine collection area to collect the initial urine. During replacement, the initial urine collection guide 501 resets, and another servo motor 504 operates, driving shaft 514 and placement frame 502 to move collection guide 501 responsible for collecting the intermediate urine. During this process, placement frame 502 can also drive the mounting... The shaft 519 rotates with one of the linkage wheels 510, which in turn, in conjunction with the linkage belt 511, causes the two linkage wheels 510 to rotate synchronously. This drives the connecting shaft 517 and the two winding wheels 518 to rotate, thereby winding up the connecting cable 507. This causes the connecting cable 507 to drive the splash baffle 508 to rise until the collection guide 501, which is responsible for sampling the middle section of urine, moves to the urine section. After sampling the middle section, the collection guide 501 and splash baffle 508 of the middle section of urine are reset, and the servo motor 504, which is responsible for sampling the rear section of urine, runs to perform sampling until the sampling of the front, middle and rear sections of urine is completed.
[0081] In specific application scenarios, the sampling anti-contamination unit 5 is suitable for the urine sampling process in medical testing. That is, the sampling anti-contamination unit 5 can reduce the splashing degree of urine when the sample container is replaced by the anti-splash mesh plate 505. At the same time, when replacing, the inner wall of the collection guide 501 will contact the urine at a certain tilt angle to further reduce the splashing degree of urine. Thus, it can work with the splash baffle 508 to completely block the splashed urine during sampling, so as to avoid the urine splashing and contaminating the intermediate sampling container, thereby ensuring the cleanliness of the intermediate sampling container and ensuring the quality of the sampled sample, thereby improving the accuracy and reliability of medical testing.
[0082] It should be noted that the collection guide 501 is a disposable item to avoid contamination. At the same time, the collection guide 501 can be quickly installed and disassembled by the fixing clamp 512 during use, reducing the difficulty of operating the device.
[0083] Reference Figures 1-3 and Figures 7-10 In a preferred embodiment, the sampling sealing module 4 further includes:
[0084] A fixed support frame 404 is set on the movable platform 3. Two rotating shafts 409 are set on the fixed support frame 404, and a rotating frame 407 is set on the two rotating shafts 409.
[0085] A general-purpose motor 401 is mounted on a fixed support frame 404. The output shaft of the general-purpose motor 401 is connected to one end of one of the rotating shafts 409 via a coupling.
[0086] Three elastic clips 405 are provided on the fixed support frame 404, and each of the three elastic clips 405 contains a container bottle 408.
[0087] Three connecting pipe seats 403 are provided on the rotating frame 407.
[0088] In this invention, the sampling sealing module 4 further includes:
[0089] Four guide rods 406 are provided on the rotating frame 407. The same movable plate 402 is provided on the four guide rods 406. A support frame 413 is provided on the movable plate 402.
[0090] Two electric push rods 415 are mounted on the rotating frame 407, and the output ends of the two electric push rods 415 are mounted on the movable plate 402.
[0091] Three fixed shafts 411 are mounted on the movable plate 402. Each of the three fixed shafts 411 is equipped with a transmission wheel 410, and every two adjacent transmission wheels 410 are equipped with the same transmission belt 414.
[0092] In this invention, the sampling sealing module 4 further includes:
[0093] The active motor 412 is mounted on the bracket frame 413, and the output shaft of the active motor 412 is connected to one end of one of the fixed shafts 411 via a coupling.
[0094] Three connecting frame compartments 419 are respectively set at the other end of three fixed shafts 411. Each of the three connecting frame compartments 419 is equipped with a negative pressure pump 420. Three fixed suction cups 417 are respectively set at the input end of the three negative pressure pumps 420.
[0095] Three sealing caps 416 are respectively set on three fixed suction cups 417. Multiple placement support rods 418 are provided on the movable plate 402, and the outer walls of the multiple placement support rods 418 are respectively in contact with the outer walls of the three sealing caps 416.
[0096] Specifically, during sampling and sealing, the sealing cap 416 is placed on the support rod 418 and brought into contact with the fixed suction cup 417. Then, the negative pressure pump 420 operates, working in conjunction with the fixed suction cup 417 to adsorb and fix the sealing cap 416. When the urine sample enters the container bottle 408, the general-purpose motor 401 operates, driving the rotating shaft to rotate, which in turn causes the rotating frame 407 to rotate, further ensuring that the guide rod 406, the movable plate 402, and the electric push rod 415 are in a vertical position. In this state, the electric push rod 415 runs and drives the movable plate 402 to move towards the container bottle 408. At the same time, the active motor 412 runs, driving the fixed shaft 411 and the transmission wheel 410 to rotate. In conjunction with the transmission belt 414, the three fixed shafts 411 run synchronously, thereby driving the connecting frame 419 to rotate, so as to further rotate the sealing cover 416 until the sealing cover 416 and the container bottle 408 are sealed together, thus completing the sealing of the urine sampling containers for the front, middle and rear sections.
[0097] In specific application scenarios, the sampling and sealing module 4 is suitable for the sampling and sealing process. That is, after the sample is taken, the sampling and sealing module 4 can perform in-situ synchronous sealing of multiple sample container bottles 408 to increase the ease of operation of the device. At the same time, the in-situ automatic sealing can avoid the misoperation that may occur during manual sealing, so as to avoid urine spillage or urine contamination caused by misoperation, ensure the safety of the operating environment and the quality of urine samples, and further enhance the effectiveness of the device.
[0098] It should be noted that when setting the sealing cover 416, the position of the sealing cover 416 can be assisted and limited by placing the support rod 418 to prevent the sealing cover 416 from shifting and to ensure the sealing is performed.
[0099] Reference Figure 3 , Figure 4 , Figure 7 and Figure 8 In a preferred embodiment, each of the three connecting ports 509 is provided with a sampling tube 12, and one end of each of the three sampling tubes 12 is respectively located inside the three connecting ports 403.
[0100] Device: The sampling connector 12 is detachable and for single use to avoid contamination.
[0101] A medical laboratory sampling method, using a medical laboratory sampling device as described above, includes the following steps:
[0102] Step 1: When setting up the collection guide 501 and container bottle 408, the handle 513 drives the fixing clamp 512 to rotate, causing the torsion spring 516 to deform. Then, the collection guide 501 is placed on the placement frame 502, and the handle 513 is released so that the torsion spring 516 returns to its original state, and the fixing clamp 512 clamps and fixes the collection guide 501. Then, the container bottle 408 is inserted into the elastic clamp 405 to complete the setting of the collection guide 501 and container bottle 408. Then, the sampling tube 12 is inserted into the connecting tube port 509 and the connecting tube seat 403 to complete the urine flow connection.
[0103] Step 2: During sampling, servo motor 504 operates, driving shaft 514 to rotate. This shaft 504, in turn, drives placement frame 502 and collection guide 501 to rotate until collection guide 501 and its splash guard 505 move to the urine collection area to collect the initial urine. Upon replacement, the initial urine collection guide 501 resets, and another servo motor 504 operates, driving shaft 514 and placement frame 502 to move collection guide 501 responsible for collecting the intermediate urine. During this process, placement frame 502 drives mounting shaft 502... 19 rotates with one of the linkage wheels 510, which in turn cooperates with the linkage belt 511 to make the two linkage wheels 510 rotate synchronously, thereby driving the connecting shaft 517 and the two winding wheels 518 to rotate, so as to wind up the connecting cable 507, thereby causing the connecting cable 507 to drive the splash baffle 508 to rise until the collection guide 501 responsible for sampling the middle section of urine moves to the urine part. After sampling in the middle section, the collection guide 501 and splash baffle 508 of the middle section of urine are reset, and the servo motor 504 responsible for sampling the rear section of urine runs to sample, until the sampling of the front, middle and rear sections of urine is completed, and the urine enters the container bottle 408;
[0104] Step 3: During the sampling process, the stepper motor 2 runs, driving the linear lead screw 8 to rotate, which in turn causes the linear lead screw 8 to move the movable platform 3 to move along with the discharge of urine.
[0105] Step 4: During sampling and sealing, the sealing cap 416 is placed on the support rod 418 and brought into contact with the fixed suction cup 417. Then, the negative pressure pump 420 operates, working in conjunction with the fixed suction cup 417 to adsorb and fix the sealing cap 416. When the urine sample enters the container bottle 408, the universal motor 401 operates, driving the rotating shaft to rotate, which in turn causes the rotating frame 407 to rotate, further ensuring that the guide rod 406, movable plate 402, and electric push rod 415 are in a vertical position. The electric push rod 415 operates, driving the movable plate 402 to move towards the container bottle 408. At the same time, the active motor 412 operates, driving the fixed shaft 411 and the transmission wheel 410 to rotate. In conjunction with the transmission belt 414, the three fixed shafts 411 operate synchronously, thereby driving the connecting frame 419 to rotate, which in turn causes the sealing cap 416 to rotate until the sealing cap 416 and the container bottle 408 are sealed together. This completes the sealing of the urine sampling containers for the front, middle and rear sections, thus completing the test sampling.
