Description

Technical Field

[0001] The present invention belongs to the technical field of midstream urine collection, and particularly relates to a midstream urine collection device with strong sealing performance. Background Art

[0002] In clinical medical examinations, midstream urine collection is a crucial step to ensure the purity of urine samples and the accuracy of test results. Traditional midstream urine collection methods require patients to first discharge a small amount of initial urine during urination to flush the contaminants at the urethral orifice, then collect the midstream urine as a sample, and finally discharge the remaining urine. However, this process highly depends on the patient's operational cooperation and subjective judgment, often unable to precisely control the urination rhythm, resulting in a blurred boundary between the initial urine and the midstream urine, such that the collected midstream urine contains some initial urine, affecting the accuracy of midstream urine collection.

[0003] Therefore, there is a need for a midstream urine collection device with strong sealing performance to solve the problem in the prior art that patients are unable to precisely control the urination rhythm, resulting in a blurred boundary between the initial urine and the midstream urine, such that the collected midstream urine contains some initial urine, affecting the accuracy of midstream urine collection.

[0037] Please refer to Figures 1-9, the present invention provides a midstream urine collection device with strong sealing performance, including a collection hopper 100. A fixing frame 101 is fixed on the inner side wall of the collection hopper 100. A contact plate 104 is arranged on one side of the fixing frame 101. Four evenly distributed positioning columns 102 are fixed on the side of the contact plate 104 close to the fixing frame 101. The positioning columns 102 are movably connected to one side surface of the fixing frame 101. Four first springs 103 are fixed between the fixing frame 101 and the contact plate 104. The first springs 103 are correspondingly arranged around the positioning columns 102. A push column 105 is fixed in the middle of the side of the contact plate 104 close to the fixing frame 101. A mortgage column 106 is fixed at the relative position of the inner side wall of the collection hopper 100 and the contact plate 104. A pressure sensor 107 is fixed at one end of the mortgage column 106. A PLC controller 108 is arranged outside the collection hopper 100. A separation component is arranged below the collection hopper 100.

[0038] Patients should drink less water or no water before going to bed, and try to retain urine in the bladder for more than 4 hours to reduce the false negative rate. After waking up naturally and feeling a sense of bladder distension, the perineum should be cleaned with soapy water or clean water. For women, the labia majora should be separated, and for men, the prepuce should be retracted and carefully cleaned, and then the urethral orifice should be rinsed with clean water. Among them, cleaning the perineum is to prevent urine specimens from being contaminated for patients with redundant prepuce or poor hygienic conditions. Female patients should avoid collecting urine specimens during menstruation.

[0039] When collecting midstream urine, the patient sits on the collection hopper 100 to urinate. The urine impacts the contact plate 104, causing the impact force of the urine on the contact plate 104 to be transmitted to the pressure sensor 107 through the push column 105, which is manifested as pressure on the pressure sensor 107. Then, the pressure sensor 107 transmits the pressure value to the PLC controller 108 in real time. The PLC controller 108 compares the pressure value received in real time with the pressure values stored inside the PLC controller 108. Among them, the PLC controller 108 stores three pressure ranges inside: the pressure range of the initial urine, the pressure range of the midstream urine, and the pressure range of the terminal urine. The pressure range of the initial urine is: 30 - 50 cmH20, the pressure range of the midstream urine is: 25 - 40 cmH20, and the pressure range of the terminal urine is: 15 - 30 cmH20. When the patient urinates the initial urine, the pressure value received by the pressure sensor 107 at this time is within the range of the initial urine, and the separation component will not work. The L-shaped tube 200 is in a normal communication state. The urine entering the aggregate 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 by the pressure sensor 107 to the PLC controller 108 is within the pressure range of the midstream urine, at this time, the urine urinated by the patient is the midstream urine. At this time, the separation component rotates, causing the L-shaped tube 200 to be blocked by the flipping block 400. This setting makes the boundary between the midstream urine and the initial urine distinct, avoiding the situation where the midstream urine collected by the patient's self-judgment contains some initial urine, which affects the accuracy of midstream urine collection.

[0040] In one embodiment, as Figure 4 、 Figure 5 and Figure 6As shown, the separation component includes an L-shaped tube 200, which is connected through the bottom of the collection hopper 100. A side hole 402 is provided on the outer wall of the L-shaped tube 200 near the top in the vertical position. A rubber tube 403 is fixed to the inner wall of the side hole 402. A turning block 400 is arranged in the L-shaped tube 200 near the top in the vertical position. A communicating tube 404 is embedded in the turning block 400. The communicating tube 404 is movably sleeved in the rubber tube 403. One end of the communicating tube 404 passes through the turning block 400. A rotating shaft 401 is fixed at the relative position of the turning block 400 and the communicating tube 404. The rotating shaft 401 is movably connected to the inner wall of the L-shaped tube 200. A positioning block 500 is fixed to the outer wall of the L-shaped tube 200 near the top in the vertical position. A first rack 501 is movably connected to one side of the top surface of the positioning block 500. A gear 503 is fixed to the outer wall of the communicating tube 404 on the side away from the turning block 400. The gear 503 meshes with the first rack 501. An electric push rod 600 is fixed to the outer wall of the L-shaped tube 200 near the top in the vertical position. 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 urine of the patient at this time is midstream urine, the PLC controller 108 controls the electric push rod 600 to start. The output end of the electric push rod 600 moves upward to drive the first rack 501 to move upward. The first rack 501 moves upward to drive the gear 503 to rotate. The gear 503 rotates to drive the communicating tube 404 to rotate. The communicating tube 404 rotates to drive the turning block 400 to rotate. The turning block 400 rotates from the vertical position to the horizontal position. With this setting, when the urine excreted by the patient is midstream urine, the L-shaped tube 200 can be blocked in time to prevent the midstream 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 communicating tube 404, then enters the connecting tube 505 and finally enters the centralized bucket 201. With this setting, the midstream urine can be pre-stored, which is convenient for the final collection of midstream urine. The rubber tube 403 is provided to ensure the sealing between the communicating tube 404 and the inner wall of the L-shaped tube 200, and prevent urine from discharging between the connection of the communicating tube 404 and the L-shaped tube 200.

[0041] In one embodiment, as Figure 7 and Figure 8As shown, a centralized bucket 201 is fixed to the bottom of the outer side wall of the collection hopper 100. A connection pipe 505 is connected through the middle of the top surface of the centralized bucket 201. A connecting pipe 504 is movably connected between the proximal end of the connection pipe 505 and the communicating pipe 404. A bottom plate 202 is fixed to the bottom of the inner side wall of the centralized bucket 201. An opening 203 is formed in the middle of the top surface of the bottom plate 202. Three triangular elastic sheets 205 distributed in a circumferential manner are fixed to the inner side wall of the opening 203. Three triangular fixing sheets 206 distributed in a circumferential manner are fixed to the inner side wall of the opening 203. A film 204 is fixed between the top surfaces of the three triangular fixing sheets 206. The urine entering the centralized bucket 201 falls on the film 204, forming pressure on the film 204, so that the tips of the three triangular fixing sheets 206 and the three triangular elastic sheets 205 can be blocked. The setting of the triangular elastic sheets 205 enables the triangular elastic sheets 205 to be pulled when discharging the urine in the centralized pipe, causing the triangular elastic sheets 205 to be deformed and misaligned, and a small gap is formed between the triangular elastic sheets 205 and the triangular fixing sheets 206. This setting, on the one hand, enables the urine to slowly drain into the bottom hopper 213 through the small gap, and on the other hand, enables only a small part of the large amount of midstream urine stored in the centralized bucket 201 to enter the bottom hopper 213. Furthermore, when the second valve 703 is opened, a small part of the midstream urine in the bottom hopper 213 can completely enter the storage container without excessive urine being discharged from the drain pipe 702, resulting in urine overflow. The setting of the connecting pipe 504 enables the communicating pipe 404 to always be sealed with the connection pipe 505 during rotation, preventing urine from flowing out between the communicating pipe 404 and the connection pipe 505.

[0042] In one embodiment, as Figure 6As shown, a bottom hopper 213 is fixed in the middle of the bottom surface of the bottom plate 202. A side pipe 700 is connected through the bottom surface of the bottom hopper 213. One end of the side pipe 700 is communicated with the L-shaped pipe 200. A first valve 701 is arranged on the outer wall of the side pipe 700. A drain pipe 702 is connected through the bottom of the outer wall of the side pipe 700 at the vertical position. A second valve 703 is arranged at the top of the outer wall of the drain pipe 702. A side opening 210 is formed on the outer wall of the bottom hopper 213 near the L-shaped pipe 200. When the pressure sensor 107 detects that the pressure value is about to approach the pressure range of the latter-stage urine, the PLC controller 108 controls the output end of the electric push rod 600 to continue to move upward, so that the turning plate changes from the horizontal state to the vertical state, and the latter-stage urine of the patient is discharged from the L-shaped pipe 200 into the sewage pipe. At this time, the position of the turning block 400 is symmetrical compared with the initial position of the turning block 400; since the middle-stage urine in the centralized bucket 201 is discharged into the bottom hopper 213 through the small gap formed between the triangular elastic piece 205 and the triangular fixing piece 206, and the latter-stage urine is directly discharged into the sewage pipe through the L-shaped pipe 200, and the urine discharge speed in the L-shaped pipe 200 is faster than that in the small gap. Therefore, when the discharge of the latter-stage urine is completed, only a small part of the urine in the centralized bucket 201 enters the bottom hopper 213, and a large amount of middle-stage urine is still stored in the centralized bucket 201. And the time of the latter-stage urine discharged after different people hold their urine is roughly the same. Therefore, after the latter-stage urine is discharged, the pressure sensor 107 cannot detect the pressure value and will transmit the information to the PLC controller 108. The PLC controller 108 controls the output end of the electric push rod 600 to move downward, and drives the movable plate 604 to move 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 restores its elasticity, pulls the push plate 212 to reset, and the triangular elastic piece 205 returns to the initial position to block the bottom plate 202. At this time, the turning block 400 is in the horizontal position. This setting enables the amount of the middle-stage urine entering the bottom hopper 213 for different people to remain relatively constant, avoiding the situation of overflow when too much urine is discharged into the urine container. Then the second valve 703 can be opened, so that the urine in the bottom hopper 213 is discharged from the drain 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 move the electric push rod 600 upward again. At this time, the flipping block 400 changes from the horizontal state to the vertical state, and the position of the flipping block 400 is symmetric with respect to its initial position. The triangular elastic piece 205 is pulled again, and a small gap is formed between the triangular elastic piece 205 and the triangular fixing piece 206. The remaining middle-section urine in the centralized bucket 201 enters the bottom hopper 213 through the small gap. Open the first valve 701, and the middle-section urine in the bottom hopper 213 is discharged into the L-shaped pipe 200 through the side pipe 700 and then enters the sewage pipe. Then, open the second valve 703 to discharge a small part of the middle-section urine at the top of the liquid discharge pipe 702 into another container. At this time, the urine stored in the other container does not overflow. After that, the PLC controller 108 can control the electric push rod 600 to return to the initial position. With this setting, the middle-section urine in the centralized bucket 201 can be collected by being discharged into the container through the liquid discharge pipe 702, and at the same time, the remaining middle-section urine in the centralized bucket 201 can be discharged for treatment.

[0043] When performing multiple tests on the middle-section urine (such as routine urine test, microbial culture, drug screening), loading it into different containers in two times can avoid contamination or loss caused by repeated sample transfer.

[0044] In one embodiment, as Figure 6As shown, on the other side of the top surface of the positioning block 500, a second rack 502 is movably connected. The second rack 502 meshes with the gear 503. A connecting bar 601 is fixed to the bottom surface of the second rack 502. A bottom post 602 is fixed to the bottom surface of the connecting bar 601. A second spring 603 is fixed to the bottom surface of the connecting bar 601. The bottom end of the second spring 603 is fixed to a movable plate 604. The movable plate 604 is movably connected to the bottom post 602. A triangular frame 208 is arranged in the bottom hopper 213. Three top posts 209 are fixed to the top surface of the triangular frame 208. A connecting rope 207 is fixed to the top surface of the top post 209. The top end 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 triangular frame 208. One end of the connecting rod 211 is fixed to a pushing plate 212. A docking hole 302 is formed in the top surface of the pushing plate 212. During the process of the flipping block 400 flipping from the vertical position to the horizontal position, the gear 503 rotates to drive the second rack 502 to move down a certain distance. When the PLC controller 108 controls the output end of the electric push rod 600 to move again, at this time, the flipping block 400 rotates from the horizontal position to the vertical position. During this process, the second rack 502 continues to move down a certain distance. The second rack 502 continues to move down, so that the bottom post 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 pushing plate 212, so that the second spring 603 is compressed, reducing the downward movement distance of the movable plate 604. However, the connecting bar 601 will continue to move down, so that the movable plate 604 can push the pushing plate 212 to move down, and then the connecting rope 207 pulls the triangular elastic piece 205 to deform and be misaligned. A small gap is formed between the triangular elastic piece 205 and the triangular fixing piece 206. This setting enables the downward movement distance of the movable plate 604 to be reduced, so that the triangular elastic piece 205 will not undergo a large deformation. On the one hand, it ensures that the gap between the triangular elastic piece 205 and the triangular fixing piece 206 becomes smaller. On the other hand, it avoids the situation where the triangular elastic piece 205 undergoes a large deformation degree, causing the triangular elastic piece 205 to be bent, affecting the reset of the triangular elastic piece 205.

[0045] In one embodiment, as Figure 6 shown, at the bottom of the vertical position on the outer side wall of the L-shaped pipe 200, a U-shaped frame 300 is fixed. Between the opposite two side surfaces of the inner side wall of the U-shaped frame 300, a limiting post 301 is fixed. The pushing plate 212 is movably connected to the limiting post 301. By providing the U-shaped frame 300 and the limiting post 301, the position of the pushing plate 212 can be movably limited, avoiding the situation where the pushing plate 212 is offset.

[0046] In one embodiment, as Figure 9As shown, a blocking ring 405 is fixed inside the connecting pipe 404. By providing the blocking ring 405, when the flipping block 400 is in a vertical state, the urine in the front section and the urine in the rear section passing through the flipping block 400 can be blocked by the blocking ring 405, preventing the urine in the front section and the urine in the rear section from entering the connecting pipe 404.

[0047] In one embodiment, as Figure 1 shown, an outer shell 800 is fixed to the outer side wall of the collection hopper 100. Two symmetrically distributed sitting plates 802 are fixed to the top surface of the outer shell 800. A support block 801 is fixed to the bottom of the inner side wall of the outer shell 800. A pick-up and placement opening 803 is formed in the bottom of the outer side wall of the outer shell 800. The PLC controller 108 is fixed to the outer side wall of the outer shell 800.
