[0002] In clinical medical testing, midstream urine collection is a key step to ensure the purity of urine samples and the accuracy of test results. The traditional midstream urine collection method requires patients to first excrete a small amount of forestream urine to flush contaminants from the urethral opening during urination, then collect midstream urine as a sample, and finally excrete the remaining urine.

[0037] See also Figures 1-9104, and a pressure sensor 107 is fixed to one end of the pressure plate 106. A PLC controller 108 is provided on the periphery of the collecting hopper 100, and a separation component is provided under the collecting hopper 100.

[0038] Patients should drink little or no water before bedtime and retain urine in the bladder for at least 4 hours to reduce the false-negative rate. After waking naturally and feeling a full bladder, the patient should cleanse the perineum with soap and water. Women should spread the labia majora, while men should retract the foreskin. Carefully cleanse the perineum and then rinse the area around the urethral opening with clean water. Cleaning the perineum is important for patients with long foreskin or poor hygiene, as it can easily contaminate urine specimens. Women should avoid collecting urine specimens during menstruation.

[0039] When collecting midstream urine, the patient sits on the collection bucket 100 to urinate, and the urine impacts the contact plate 104, so that the impact force of the urine on the contact plate 104 is transmitted to the pressure sensor 107 through the push column 105, and is manifested as pressure on the pressure sensor 107. Then the pressure sensor 107 transmits the pressure value in real time to the PLC controller 108, and the PLC controller 108 compares the real-time received pressure value with the pressure value stored in the PLC controller 108. Among them, the PLC controller 108 stores three pressure ranges: the front urine pressure range, the middle urine pressure range and the back urine pressure range; the front urine pressure range is: 30-50cmH20, the middle urine pressure range is: 25-40cmH20, and the back urine pressure range is: 15-30c mH20, when the patient urinates the front urine, the pressure value received by the pressure sensor 107 is within the range of the front urine, the separation component will not work, the L-shaped tube 200 is in a normal connected state, the urine entering the collecting hopper enters the L-shaped tube 200 and is discharged from the L-shaped tube 200 into the indoor sewage pipe (one end of the L-shaped tube 200 is connected to the indoor sewage pipe). When the pressure value transmitted to the PLC controller 108 by the pressure sensor 107 is within the pressure range of mid-stream urine, the urine urinated by the patient is mid-stream urine. At this time, the separation component rotates, so that the inside of the L-shaped tube 200 is blocked by the flip block 400. This setting makes the boundary between mid-stream urine and front urine clearly distinguishable, avoiding the patient's independent judgment that the collected mid-stream urine contains part of the front urine, affecting the accuracy of the mid-stream urine collection.

[0040] In one embodiment, if Figure 4 、 Figure 5 and Figure 6As shown, the separation component includes an L-shaped tube 200, which is connected to the bottom of the collecting bucket 100, and a side hole 402 is opened on the outer wall of the L-shaped tube 200 near the top in a vertical position. A rubber tube 403 is fixed to the inner wall of the side hole 402, and a flip block 400 is provided at a vertical position near the top in the L-shaped tube 200. A connecting tube 404 is embedded in the flip block 400, and the connecting tube 404 is movably sleeved in the rubber tube 403. One end of the connecting tube 404 passes through the flip block 400, and a rotating shaft 401 is fixed to the relative position of the flip block 400 and the connecting tube 404. The rotating shaft 401 is movably connected to the inner wall of the L-shaped tube 200, and a positioning block 500 is fixed on the outer wall of the L-shaped tube 200 near the top in a vertical position. A first rack 501 is movably connected to one side of the top surface of the positioning block 500, and the connecting tube 404 A gear 503 is fixed to the side of the outer wall away from the flip block 400, and the gear 503 is meshed with the first rack 501. An electric push rod 600 is fixed to the outer wall near the top of the vertical position of the L-shaped tube 200, and the output end of the electric push rod 600 is fixed to the bottom surface of the first rack 501. When the PLC controller 108 detects that the patient's urine is mid-stream urine at this time, the PLC controller 108 controls the electric push rod 600 to start, and the output end of the electric push rod 600 moves upward to drive the first rack 501 to move upward. The upward movement of the first rack 501 drives the gear 503 to rotate, and the rotation of the gear 503 drives the connecting pipe 404 to rotate. The rotation of the connecting pipe 404 drives the flip block 400 to rotate, and the flip block 400 rotates from a vertical position to a horizontal position. This arrangement enables the L-shaped tube 200 to be blocked in time when the urine urinated by the patient is mid-stream urine, thereby preventing mid-stream urine from being discharged from the L-shaped tube 200 into the sewage pipe. The urine entering the top of the L-shaped tube 200 enters the connecting tube 404, then enters the connecting tube 505 and finally enters the collecting bucket 201. This arrangement enables the midstream urine to be stored in advance, facilitating the final midstream urine collection. The rubber tube 403 is arranged to ensure the sealing of the connecting tube 404 and the inner wall of the L-shaped tube 200, thereby preventing urine from being discharged from the connection between the connecting tube 404 and the L-shaped tube 200.

[0041] In one embodiment, if Figure 7 and Figure 8As shown, a centralizing barrel 201 is fixed to the bottom of the outer wall of the collecting bucket 100, a connecting pipe 505 is connected to the middle of the top surface of the centralizing barrel 201, and a connecting pipe 504 is movably connected between the connecting pipe 505 and the proximal end of the connecting pipe 404. A bottom plate 202 is fixed to the bottom of the inner wall of the centralizing barrel 201, an opening 203 is opened in the middle of the top surface of the bottom plate 202, three triangular elastic pieces 205 distributed in a circle are fixed to the inner wall of the opening 203, three triangular fixing pieces 206 distributed in a circle are fixed to the inner wall of the opening 203, and a covering film 204 is fixed between the top surfaces of the three triangular fixing pieces 206. The urine entering the centralizing barrel 201 falls on the covering film 204, which forms pressure on the covering film 204, so that the three The triangular fixing piece 206 and the three triangular elastic pieces 205 can be blocked at their tips. The arrangement of the triangular elastic pieces 205 allows the urine in the collecting tube to be discharged by pulling the triangular elastic pieces 205, causing them to deform and dislocate, forming a small gap between the triangular elastic pieces 205 and the triangular fixing pieces 206. This arrangement, on the one hand, allows urine to slowly drain into the bottom bucket 213 through the small gap, and on the other hand, ensures that only a small portion of the large amount of mid-stream urine stored in the collecting bucket 201 enters the bottom bucket 213. This facilitates the complete discharge of the small amount of mid-stream urine in the bottom bucket 213 into the holding container when the second valve 703 is opened, preventing excessive urine from being discharged from the discharge tube 702 and causing urine overflow. The arrangement of the connecting pipe 504 ensures that the connecting pipe 404 is always sealed against the connecting pipe 505 during rotation, preventing urine from flowing out between the connecting pipe 404 and the connecting pipe 505.

[0042] In one embodiment, if Figure 6As shown, a bottom bucket 213 is fixed to the middle of the bottom surface of the bottom plate 202, and a side pipe 700 is connected to the bottom of the bottom bucket 213. One end of the side pipe 700 is connected to the L-shaped pipe 200. A first valve 701 is provided on the outer wall of the side pipe 700. A drain pipe 702 is connected to the bottom of the vertical position of the outer wall of the side pipe 700. A second valve 703 is provided on the top of the outer wall of the drain pipe 702. A side port 210 is opened on the outer wall of the bottom bucket 213 near the L-shaped pipe 200. When the pressure When the sensor 107 detects that the pressure value is about to approach the pressure range of the posterior urine, the PLC controller 108 controls the output end of the electric push rod 600 to continue to move upward, so that the flip plate changes from a horizontal state to a vertical state, and the patient's posterior urine is discharged from the L-shaped tube 200 into the sewage pipe. At this time, the position of the flip block 400 is symmetrical compared to the initial position of the flip block 400; since the middle urine in the concentrated barrel 201 is discharged into the bottom hopper 213 through the small gap formed between the triangular elastic piece 205 and the triangular fixed piece 206, the posterior urine The urine is discharged directly into the sewage pipe through the L-shaped tube 200. The L-shaped tube 200 has a faster discharge speed than the urine in the small gap. Therefore, after the discharge of the latter part of the urine is completed, only a small part of the urine in the collection bucket 201 enters the bottom bucket 213, and a large amount of middle-part urine is still stored in the collection bucket 201. The time for different people to discharge the latter part of the urine after holding urine is roughly the same. Therefore, after the latter part of the urine is discharged, the pressure sensor 107 cannot detect the pressure value, and the information will be transmitted to the PLC controller 108. The PLC controller 108 controls the electric push button. The output end of the rod 600 moves downward, and the movable plate 604 moves upward through the transmission of the first rack 501, the gear 503, and the second rack 502. During this process, the triangular elastic piece 205 recovers its elastic force, pulling the push plate 212 back to its original position, and the triangular elastic piece 205 returns to its initial position, blocking the bottom plate 202. At this time, the flip block 400 is in a horizontal position. This arrangement ensures that the amount of mid-stream urine entering the bottom hopper 213 by different people can be kept relatively constant, preventing excessive urine from overflowing from the urine container. The second valve 703 can then be opened, allowing the urine in the bottom hopper 213 to be discharged through the drainage pipe 702 into the urine container on the support block 801 without overflowing.Then close the second valve 703, and operate the PLC controller 108 to make the electric push rod 600 move up again. At this time, the flip block 400 changes from a horizontal state to a vertical state. The position of the flip block 400 is symmetrical with the initial position of the flip block 400. The triangular elastic piece 205 is pulled again, and a small gap is formed between the triangular elastic piece 205 and the triangular fixed piece 206. The remaining middle urine in the bucket 201 flows into the bottom hopper 213 through the small gap. The first valve 701 is opened, and the urine in the bottom hopper 213 is discharged. The midstream urine is discharged from the side tube 700 into the L-shaped tube 200 and into the sewage pipe, and then the second valve 703 is opened to allow a small part of the midstream urine at the top of the drainage pipe 702 to be discharged into another container. At this time, the urine stored in the other container has not overflowed. After that, the PLC controller 108 can control the electric push rod 600 to return to its initial position. This setting allows the midstream urine in the collection barrel 201 to be discharged from the drainage pipe 702 into the container for collection, and at the same time, the remaining midstream urine in the collection barrel 201 can be discharged and processed.

[0043] When performing multiple tests on midstream urine (such as routine urine test, microbial culture, and drug screening), dividing the urine into two different containers can avoid contamination or loss caused by repeated sample transfer.

[0044] In one embodiment, if Figure 6As shown, the other side of the top surface of the positioning block 500 is movably connected to a second rack 502, the second rack 502 is meshed with the gear 503, the bottom surface of the second rack 502 is fixed with a connecting bar 601, the bottom surface of the connecting bar 601 is fixed with a bottom column 602, the bottom surface of the connecting bar 601 is fixed with a second spring 603, the bottom end of the second spring 603 is fixed with a movable plate 604, the movable plate 604 is movably connected to the bottom column 602, the bottom bucket 213 is provided with a tripod 208, the top surface of the tripod 208 is fixed with a There are three top columns 209, and a connecting rope 207 is fixed on the top surface of the top column 209. The top of the connecting rope 207 is fixed to the bottom surface of the corresponding triangular elastic piece 205. A connecting rod 211 is fixed to the bottom surface of the tripod 208. A push plate 212 is fixed at one end of the connecting rod 211. A docking hole 302 is opened on the top surface of the push plate 212. When the flip block 400 flips from the vertical position to the horizontal position, the gear 503 rotates and drives the second rack 502 to move down a distance. When the PLC controller 108 controls the output of the electric push rod 600, When the output end moves again, the flip block 400 rotates from the horizontal position to the vertical position. During this process, the second rack 502 continues to move downward for a distance, and the second rack 502 continues to move downward, so that the bottom column 602 is inserted into the docking hole 302. Since the triangular elastic piece 205 has elasticity, the triangular elastic piece 205 is equivalent to having a certain limiting effect on the push plate 212, so that the second spring 603 is compressed, reducing the downward movement distance of the movable plate 604, but the connecting bar 601 will continue to move downward, so that the movable plate 604 can push the push plate 212 The movable plate 604 moves downward, and the connecting rope 207 pulls the triangular elastic piece 205 to deform and dislocate, and a small gap is formed between the triangular elastic piece 205 and the triangular fixed piece 206. This arrangement reduces the downward movement distance of the movable plate 604, so that the triangular elastic piece 205 does not deform significantly. On the one hand, it ensures that the gap between the triangular elastic piece 205 and the triangular fixed piece 206 becomes smaller. On the other hand, it avoids the triangular elastic piece 205 from deforming to a large extent, causing the triangular elastic piece 205 to bend, which affects the reset of the triangular elastic piece 205.

[0045] In one embodiment, if Figure 6 As shown, a U-shaped frame 300 is fixed at the bottom of the vertical position of the outer wall of the L-shaped tube 200, and a limiting column 301 is fixed between the two opposite side surfaces of the inner wall of the U-shaped frame 300. The push plate 212 is movably connected to the limiting column 301. By setting the U-shaped frame 300 and the limiting column 301, the position of the push plate 212 can be movably limited to avoid the push plate 212 from being offset.

[0046] In one embodiment, if Figure 9As shown, a blocking ring 405 is fixed inside the connecting tube 404. Through the setting of the blocking ring 405, when the flip block 400 is in a vertical state, the front urine and the back urine passing through the flip block 400 can be blocked by the blocking ring 405, preventing the front urine and the back urine from entering the connecting tube 404.

[0047] In one embodiment, if Figure 1 As shown, a shell 800 is fixed to the outer wall of the collecting bucket 100, two symmetrically distributed sitting boards 802 are fixed to the top surface of the shell 800, a support block 801 is fixed to the bottom of the inner wall of the shell 800, and a take-in and put-out port 803 is provided at the bottom of the outer wall of the shell 800. The PLC controller 108 is fixed to the outer wall of the shell 800. By setting the sitting board 802, when the patient sits on the collecting bucket 100, the sitting board 802 can increase the contact area with the patient's buttocks, thereby avoiding discomfort when the patient sits directly on the collecting bucket 100.

[0048] The triangular elastic sheet 205 is treated by galvanizing to achieve corrosion resistance of the triangular elastic sheet 205 ; the connecting rope 207 is made of polypropylene and is resistant to urine corrosion.

[0049] The pressure sensor 107 , the PLC controller 108 , and the coating 204 can all be purchased from the market. They are mature technologies in this field and have been fully disclosed, so they will not be repeated in the specification.

[0050] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
