Description

Technical Field

[0001] The invention relates to the technical field of urine testing sampling, and in particular to a urine testing sampling device. Background Art

[0002] Urine sampling is a common medical testing method, mainly used for disease diagnosis, health monitoring, drug testing, preventive screening and pregnancy confirmation. This non-invasive, simple and fast method provides doctors with important health information and helps to formulate appropriate treatment plans.

[0003] According to clinical guidelines, during the urination process, the back urine (i.e., urine about 1 to 2 seconds after the start of urination) is collected. This part of urine is usually the cleanest and contains more accurate components. The urine in the first 1 to 2 seconds may contain external contaminants (such as bacteria and secretions), while the back urine is relatively cleaner and can better represent the sample composition in the bladder because it can be mixed more evenly during the process of urine excretion, reflecting the true state of the body. If the back urine is not collected for testing, the urine sample may contain external bacteria, secretions and other contaminants, which may interfere with the test results and cause misdiagnosis or false positive / false negative results.

[0004] Moreover, in the process of sampling, the existing device usually uses a disposable paper cup for collection, and then pours it into a collection test tube for collection. In this way, without taking segmentation measures, the front urine is easily mixed with the back urine. In this way, even if the back urine is collected, the back urine will also interfere with the test results, and the disposable paper cup is wasted. After searching, a urine test sampling device disclosed in the publication number CN117232909B does not sample the back urine during the sampling process. The above method has errors in the test results. It can be used for ordinary patients, but for some patients with severe kidney disease in the ICU, it is difficult to accurately collect the back urine. It is very important to test the posterior urine because the posterior urine can more accurately reflect the components in the bladder and reduce the interfering substances in the anterior urine, which plays a significant role in enabling doctors to make targeted adjustments to treatment in a timely manner according to the slightly changed detection parameters; if segmented sampling is adopted, intermittent separate sampling is required, so that when the patient's bladder is filled to a certain extent, the strong urge to urinate will prompt the patient to continue urinating. If the patient needs to stop temporarily at this time, this may cause discomfort and a feeling of holding urine; and the continuous discharge of urine requires manual movement of the collection tube to the position where urine is discharged, so that the outer wall of the collection tube is easily in contact with urine, causing the collection tube to become dirty. Therefore, the present invention proposes a urine test sampling device that can collect the posterior urine, avoid the anterior urine from affecting the test results, and can be reused. Summary of the invention

[0022] Third, cleaning water is injected into the cleaning tank through the external water injection equipment of the joint, and the cleaning water is used to clean the part of the device that carries urine. While the cleaning water is injected, the cleaning water will drive the fan blades and the cam to rotate, and the rotating cam will drive the linkage rod, the lifting rod and the inclined slide block to rise and fall through the slide groove, and the inclined slide block will slide in contact with the inclined groove during the lifting process to allow each discharge port to circulate, so as to clean the discharge port.

[0049] The working principle of the present invention is as follows:

[0050] 1. Collect the first part of the urine

[0051] The device is fixed at the position where urine needs to be collected, and then the patient can urinate into the collection tube 201. When the urine enters the collection tube 201, it flows through the auger shaft 210. The front urine (the urine of the first 1 to 2 seconds) will first flow through the collection tube 201 to the upper end of the partition 204, and then flow into the lifting tube 203 through the liquid inlet 217. During this process, the patient does not need to interrupt urination. When the front urine flows into the lifting tube 203, it will increase the weight of the lifting tube 203 and compress the first spring 208, increasing the pressure. The heavy lifting tube 203 will slide downward in the sealing tube 202 and squeeze the air in the sealing tube 202. The squeezed air in the sealing tube 202 will flow into the bellows telescopic tube 215 through the exhaust groove 209 and the air inlet pipe 214, so that the bellows telescopic tube 215 will expand in the fixing box 213. The expanded bellows telescopic tube 215 will drive the magnetic sealing plate 216 to slide. The two pairs of magnetic sealing plates 216 slide relative to each other to seal the liquid inlet 217, blocking the rear urine from flowing into the lifting tube 203. The front urine will be completely separated from the rear urine.

[0052] 2. Collect posterior urine

[0053] When the patient continuously discharges the posterior urine, the urine will continuously fill the collecting tube 201 until the patient has completely discharged the urine. The urine can then be collected. The rectangular block 306 is pushed to drive the first sliding frame 301 to slide in the collecting tube 201 and compress the second spring 305. The sliding first sliding frame 301 will drive the push rod 303 to move together. After moving a certain distance, the push rod 303 will contact the second sliding frame 411 and squeeze the second sliding frame 411. After being squeezed, the second sliding frame 411 will drive the second sealing block 412 to move. 10 slides in the liquid outlet pipe 401 and compresses the fifth spring 417. The second sealing block 410 drives the screw sleeve 408 and the sliding rod 409 to move during the sliding process, and the sliding rod 409 drives the sliding box 413 and the limiting rod 414 to slide and compress the fourth spring 415. The second sealing block 410 that slides a certain distance slides from the limiting section to the position of the wide diameter section. The diameter of the wide diameter section is larger than that of the second sealing block 410. Therefore, a flow gap is generated between the second sealing block 410 and the wide diameter section, and urine flows to the pipe section of the liquid outlet pipe 401 through the flow gap for collection.

[0054] 3. The position of the second sliding frame 411 is controlled according to the required sample volume so that before the Z-shaped block 308 contacts the triangular stopper 313, the second sliding frame 411 can drive the second sealing block 410 to move to complete the urine collection. Specifically:

[0055] It should be noted that, since the amount of urine discharged by each patient is different, the device will discharge the excess urine in the collection tube 201 after collecting the urine. The type and purpose of the test determine that the number of milliliters of urine collected is different. In order to discharge the excess urine after reaching the collected amount of urine, the torsion bar 416 can be twisted to allow the limit rod 414 to drive the sliding box 413 and the sliding rod 409 to rotate. During the rotation, the sliding rod 409 will drive the screw sleeve 408 to rotate. The rotating screw sleeve 408 will be threadedly connected to the threaded rod 412 and drive the threaded rod 412 to retract. The retractable threaded rod 412 will drive the second sliding frame 411 to move. At this time, the second sliding frame 411 will shorten the distance between it and the top rod 303. In this way, in the process of pushing the first sliding frame 301 to move, the top rod 303 will contact the second sliding frame 411 in advance and push the second sealing block 410 to the position of the wide groove for drainage and collection. Then, in the process of the first sliding frame 301 being continuously driven to move, the Z-shaped block 308 will contact the triangular block 313, and drive the triangular block 313 and the connecting rod 312 to slide in the sliding baffle 311 and the liquid outlet head 309, so that the connecting rod 312 drives the first sealing block 315 to slide over the position of the drainage pipe 310, and at this time, the urine is discharged outward through the drainage pipe 310. In the process of the first sliding frame 301 moving, the tooth plate 302 will mesh with the gear ring 316 and drive the gear ring 316 and the auger shaft 210 to rotate. The rotating auger shaft 210 will stir the urine to a certain extent to prevent the sedimentation of urine and improve the uniformity of urine. When the auger shaft 210 rotates, it will drive the rotating plate 212 to rotate. The rotating rotating plate 212 will form a sealing surface with the baffle 211 to seal the collection pipe 201 to prevent foreign matter from entering the collection pipe 201 and causing pollution.

[0056] The sampling tube is slidably placed between the clamp heads 403, and the upper end of the sampling tube corresponds to the lower end of the liquid outlet tube 401. In the process of sliding the sampling tube between the clamp heads 403, the sampling tube will slide in contact with the rotating disk 406 and drive the rotating disk 406 to rotate. The rotating rotating disk 406 will drive the rotating rod 404 and the first sealing plate 405 to rotate together. When the sampling tube is completely placed between the clamp heads 403 corresponding to the lower end of the liquid outlet tube 401, the first sealing plate 405 will rotate 90° to allow urine to pass through. After the sampling tube has collected urine, the sampling tube will be taken out from between the clamp heads 403. It will also slide in contact with the rotating disk 406 and drive the first sealing plate 405 to rotate 90°. At this time, the first sealing plate 405 will seal the liquid outlet tube 401 to prevent urine from dripping.

[0057] 4. Backwashing instructions

[0058] After collecting urine, the cleaning water is injected into the cleaning tank 509 through the external water injection device connected to the joint 510. The cleaning water will flow into the lifting pipe 203 through the one-way valve 206, and flow into the collection pipe 201 through the liquid inlet 217 and finally spray out to clean the device. When the cleaning water flows into the cleaning tank 509, the cleaning water will drive the fan blade 504 and the cam 503 to rotate. The rotating cam 503 will drive the linkage rod 505 to rise and fall through the slide groove. The linkage rod 505 is in motion. During the lifting process, the second sealing plate 506 will be driven to lift together to prevent the cleaning water from flowing out. The lifting linkage rod 505 will drive the lifting rod 507 and the inclined sliding block 508 to lift together, and the inclined sliding block 508 will slide in contact with the inclined groove during the lifting process, thereby driving the first sliding frame 301 to slide in the collection tube 201, allowing the cleaning water to flow into the liquid outlet pipe 401, the liquid outlet head 309 and the discharge pipe 310 for cleaning, so as to facilitate the subsequent reuse of the device for the next collection.
