[0002] Urinalysis is a crucial diagnostic tool in nephrology clinical practice. Urine contains a wealth of physiological and pathological information, which is crucial for assessing kidney function, diagnosing kidney disease, and monitoring treatment efficacy. However, traditional urine collection methods often present challenges, such as high contamination risk, inconvenient operation, and a poor patient experience.

[0003] The urine used for urine tests is usually midstream urine, because midstream urine has the lowest probability of bacterial contamination and is closest to the actual situation in the bladder. Midstream urine is the smoothest and has the most stable flow rate. Nowadays, samples are taken directly from the open container when convenient. It is relatively easier for men, but if the hands shake, urine may get on the hands, and it is more difficult for women. Summary of the Invention

The upper wall of the funnel 13 is smooth and coated with hydrophobic material. A sampling mechanism for sampling is provided in the support tube 12.

[0029] like Figure 4-Figure 6As shown, the sampling mechanism includes an adjustment component 3, a cross 31, a liquid outlet pipe 32, a sampling inner pipe 33, a sampling outer pipe 34, a sampling pipe 35, a valve pipe 36 and a cross baffle 361. The support pipe 12 is provided with an adjustment component 3 for adjusting the sampling range. The lower end of the adjustment component 3 is rotatably connected to the sampling outer pipe 34. The cross 31 is fixed to the base 1. The top of the liquid outlet pipe 32 is sealed with the bottom end of the guide pipe 14. The bottom of the liquid outlet pipe 32 is sealed and connected to the sampling inner pipe 33. The sampling inner pipe 33 is slidably connected to the sampling outer pipe 34. The bottom end of the sampling inner pipe 33 is rotatably connected to the valve pipe 36. The lower end of the liquid outlet pipe 32 The end passes through the base 1 and is fixed to the base 1. The top of the liquid outlet pipe 32 is rotatably connected to the bottom of the valve tube 36. A sampling tube 35 for collecting urine is provided on the outside of the sampling outer tube 34. A cross baffle 361 is provided on the top of the valve tube 36. A cross through hole is provided at the bottom of the sampling inner tube 33. The cross baffle 361 is in close contact with the bottom of the cross through hole and is used to seal the cross through hole. The sampling outer tube 34 is provided with a circular tube protruding outward. The inner diameter of the circular tube at the opening of the sampling tube 35 is equal to the outer diameter of the circular tube protruding from the sampling outer tube 34, and a petal rubber sheet is provided at the opening of the sampling tube 35 to prevent the liquid in the sampling tube 35 from flowing back.

[0030] like Figure 7 and Figure 8 As shown, the adjustment component 3 includes a first fixing ring 301, a tube sleeve frame 302, a first limiting ring 303, a first limiting rod 304 and a first elastic member 305. The first fixing ring 301 is fixed to the bottom of the support tube 12. The first fixing ring 301 is bent to form a hole with the support tube 12. The upper end of the tube sleeve frame 302 is slidably connected to the hole formed by the first fixing ring 301 and the support tube 12. The lower end of the tube sleeve frame 302 is slidably connected to the sampling outer tube 34. The outer side of the first limiting ring 303 is fixed to the support tube 12. The outer side of the first limiting ring 303 is slidably connected to the There is a first limiting rod 304, the outer end of the first limiting rod 304 is slidably connected to the top of the tube sleeve holder 302, the outer end of the first limiting rod 304 is trapezoidal, and the upper and lower surfaces are inclined surfaces. A first elastic member 305 is sleeved on the first limiting rod 304, one end of the first elastic member 305 is connected to the first limiting rod 304, and the other end is connected to the first limiting ring 303. A plurality of through holes of three heights are opened on the sampling inner tube 33, and grooves of three heights are provided on the tube sleeve holder 302, and the spacing between the through holes and the grooves is equal. The through holes of the sampling inner tube 33 are connected to the round tube of the sampling outer tube 34.

[0031] The overall structure composed of the base 1, the support tube 12 and the outer frame tube 15 can support a vertical weight of 200 kg, so when an adult sits on it, the overall structure can remain stable. When a man uses it, he can directly defecate into the funnel 13, and the urine flows in the order of the funnel 13-the guide tube 14-the sampling inner tube 33-the valve tube 36. Since the cross hole at the bottom of the sampling inner tube 33 is sealed by the cross baffle 361 on the valve tube 36, the front part of the urine is in the sampling inner tube 33. At the bottom, since the through hole on the sampling inner tube 33 is connected to the circular tube of the sampling outer tube 34, and the circular tube of the sampling outer tube 34 is connected to the circular tube of the sampling tube 35, the midstream urine flows into the sampling tube 35 through the through hole of the sampling inner tube 33 and the circular tube of the sampling outer tube 34 to complete the collection. The sampling baffle 11 is opened and the sampling outer tube 34 is rotated to make the through hole of the sampling inner tube 33 and the circular tube of the sampling outer tube 34 misaligned, so that the liquid in the sampling inner tube 33 cannot flow out through the sampling outer tube 34. The sampling tube 35 is lowered, and then the valve tube 36 is twisted to dislocate the cross baffle 361 from the cross hole at the bottom of the sampling inner tube 33. After the remaining urine passes through the valve tube 36, it flows out along the liquid outlet pipe 32. Then, the flushing function is used to flush the funnel 13. Since the surface of the funnel 13 is coated with a hydrophobic material, the urine will flow directly along the inner wall of the funnel 13, reducing the retention and causing the mixing of the front and rear urine. Moreover, when flushing, the water will also flow down along the funnel 13, according to the funnel. The urine flows out in the order of bucket 13 - diversion tube 14 - sampling inner tube 33 - valve tube 36 - liquid outlet tube 32, flushing away the residual urine without affecting the next use. The woman sits on the outer frame tube 15 and completes the collection of urine through the above steps. After the flushing is completed, a new sampling tube 35 is inserted, and the valve tube 36 is screwed back to align the cross baffle 361 with the cross through hole at the bottom of the sampling inner tube 33. The sampling outer tube 34 is turned back to align the through hole of the sampling inner tube 33 with the round tube of the sampling outer tube 34.

[0032] It should be added that when flushing, the motor 2 is turned on, and the gear 21 of the motor 2 drives the ring gear 22 to rotate, thereby rotating the scraper frame 23 to scrape the funnel 13. After the flushing is completed, the motor 2 is turned off after a period of time, so that the water can be quickly hung into the guide tube 14.

[0033] It should also be added that there are differences in urine volume for people of different ages, or for patients with urethral obstruction, the single urine volume may be less. The sampling range can also be adjusted according to the urine sensation at the time. Before sampling, the sampling baffle 11 is opened. If the urine sensation is strong, the tube sleeve frame 302 is pushed upward. The tube sleeve frame 302 slides along the first fixing ring 301, so that the first limiting rod 304 originally connected to the groove of the tube sleeve frame 302 is squeezed, so that the first limiting rod 304 slides toward the middle along the first limiting ring 303 and further compresses the first elastic member 305. The compressed first elastic member 305 pushes the first limiting rod 304, so that the outer end of the first limiting rod 304 is always in contact with the tube sleeve frame 302. Therefore, when the outer end of the first limiting rod 304 is aligned with the next groove of the tube sleeve rack 302, the outer end of the first limiting rod 304 directly cooperates with the groove of the tube sleeve rack 302, and people can feel the resistance to pushing the tube sleeve rack 302 increases instantly. The moving tube sleeve rack 302 drives the sampling outer tube 34 and the sampling tube 35 to move together. The first limiting rod 304 cooperates with the grooves of the tube sleeve rack 302 at different heights, and the moving sampling outer tube 34 also cooperates with the through holes of the sampling inner tube 33 at different heights. When the sampling outer tube 34 and the sampling tube 35 move upward, the height distance below the corresponding through hole of the sampling inner tube 33 increases, and the volume also increases accordingly, thereby making the sampling of mid-stream urine more accurate. If the urine volume is small and the urine sensation is weak, the tube sleeve rack 302 is pulled to the bottom.

[0034] like Figure 9 and Figure 10 As shown, it also includes a spider leg frame 4, a second fixing ring 41, a second limiting ring 42, a second limiting rod 43 and a second elastic member 44. The spider leg frame 4 is fixedly connected to the bottom of the sampling outer tube 34, and the second limiting ring 42 is fixedly connected to the outer ring of the valve tube 36. The spider leg frame 4 is slidably connected to the second limiting ring 42. The second fixing ring 41 is fixedly connected to the outer side of the base 1. The second limiting rod 43 is slidably connected to the second fixing ring 41. The inner end of the second limiting rod 43 is slidably connected to the second limiting ring 42. The inner end of the second limiting rod 43 is trapezoidal, and the left and right surfaces are inclined surfaces. Eight second limiting rods 43 are evenly arranged on the second fixing ring 41, so that the angle between the second limiting rods 43 is 45 degrees. A second elastic member 44 is sleeved on the second limiting rod 43. One end of the second elastic member 44 is connected to the second limiting rod 43, and the other end is connected to the second fixing ring 41.

[0035] When the sampling outer tube 34 is twisted, the fixed spider leg frame 4 also rotates, and the spider leg frame 4 drives the second limiting ring 42 to rotate. The second limiting ring 42 slides with the second limiting rod 43, and the compressed second elastic member 44 always pushes the second limiting rod 43 to make close contact with the second elastic member 44. It is more labor-saving to directly rotate the spider leg frame 4 or the second limiting ring 42. After rotating 45 degrees, the second limiting ring 42 is engaged with the next groove of the second limiting rod 43, and the sampling outer tube 34 is rotated. After the outer sampling tube 34 and the valve tube 36 are rotated 45 degrees, since the through-holes of the sampling inner tube 33 are spaced at an angle of 90 degrees, and the circular tube of the outer sampling tube 34 is also 90 degrees, and the cross through-holes at the bottom of the sampling inner tube 33 are in the shape of a "cross", the through-holes of the sampling inner tube 33 are completely misaligned with the circular tube of the sampling outer tube 34, and the cross through-holes of the sampling inner tube 33 are completely misaligned with the cross baffle 361. The sampling inner tube 33 is connected to the valve tube 36 while being sealed with the outer sampling tube 34, making operation more convenient.

[0036] like Figure 11 and Figure 12 As shown, it also includes a bending rod 5, a knocking rod 51, a guide sleeve 52, a third elastic member 53 and an extrusion block 54. The bending rod 5 is fixed to the top of the gear ring 22, the guide sleeve 52 is fixed to the support tube 12, the knocking rod 51 passes through the support tube 12, and is slidably connected to the guide sleeve 52. The inner end of the knocking rod 51 contacts the outer wall of the guide tube 14, and the outer end of the knocking rod 51 is fixed with an extrusion block 54. The extrusion block 54 is slidably connected to the bending rod 5. The knocking rod 51 is sleeved with a third elastic member 53, one end of the third elastic member 53 is connected to the guide sleeve 52, and the other end is connected to the knocking rod 51.

[0037] When the motor 2 is in the on state, the ring gear 22 drives the bending rod 5 to rotate, and the bottom of the bending rod 5 contacts the extrusion block 54. Since the two sides of the top of the extrusion block 54 are inclined surfaces, when the extrusion block 54 contacts the bending rod 5, it will be squeezed outward by the bending rod 5, and at the same time drive the knocking rod 51 to move outward. The moving knocking rod 51 compresses the third elastic member 53. When the extrusion block 54 is disengaged from the bending rod 5, the third elastic member 53 rebounds, causing the knocking rod 51 to slide inward along the guide sleeve 52, and the inner end directly collides with the outer wall of the guide tube 14, knocking the water stuck on the inner wall of the guide tube 14, so that the guide tube 14 can dry quickly without affecting the next use of the sampling device.

[0038] like Figure 1 As shown, it also includes a pipe cover 6, a connecting seat 61 and a spray rack 62. The connecting seat 61 is fixedly connected to the outer wall of the outer frame tube 15. The pipe cover 6 is rotatably connected to the connecting seat 61, and the area of the pipe cover 6 is larger than the area of the top opening of the outer frame tube 15. The pipe cover 6 is provided with a spray rack 62, and the nozzle of the spray rack 62 passes through the pipe cover 6.

[0039] When it is determined that the device will not be used for a period of time, the tube cover 6 can be closed and additional cleaning and disinfecting liquid can be used to clean and disinfect the inside of the sampling device through the spray rack 62 to prevent the growth of bacteria and the entry of foreign objects to cause contamination, thereby ensuring the effectiveness of the device.

[0040] like Figure 2 and Figure 4 As shown, a guide tube rack 7 is also included. The guide tube rack 7 is fixedly connected to the sampling outer tube 34. The circular hole of the guide tube rack 7 is concentric with the circular hole of the sampling outer tube 34. The sampling tube 35 is slidably connected to the guide tube rack 7.

[0041] When inserting and removing the sampling tube 35, the sampling tube 35 can be moved horizontally through the guide tube holder 7, and will not swing upward when being removed, thereby damaging the round tube of the sampling outer tube 34 and causing the round tube to bend. The horizontal insertion and removal can ensure the sealing of the connection between the sampling tube 35 and the sampling outer tube 34, which is conducive to extending the service life.

[0042] Although the present disclosure has been shown and described with reference to certain exemplary embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made to the present disclosure without departing from the spirit and scope of the present disclosure as defined by the appended claims and their equivalents. Therefore, the scope of the present disclosure should not be limited to the above-described embodiments, but should be determined not only by the appended claims but also by the equivalents of the appended claims.
