Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a urine sampling and testing component for urology. Background Technology

[0002] In the clinical diagnosis of urology, urine sampling and testing is a crucial step. As one of the body's excretions, the composition and properties of urine can directly reflect the health of the urinary system. By analyzing urine, doctors can determine whether a patient has a urinary tract infection, inflammation, bleeding, or other urinary system diseases, thus providing an important basis for subsequent treatment. Traditionally, urological testing typically relies on patients urinating into a measuring cup, which is then poured into a urine test tube for testing. However, to improve diagnostic accuracy, "midstream urine" is often used as the test sample during routine urination. Midstream urine refers to the urine collected from the beginning of the urination process to flush the urethra and reduce external contamination. The urine from the middle section is then collected as the test sample, and finally the urine from the end of the urination is expelled. This step aims to ensure the representativeness and purity of the urine sample, thereby avoiding the influence of external factors on the test results. However, current urine sampling methods face a series of challenges and shortcomings in practice. First, from the perspective of patient experience, requiring patients to judge and urinate in segments undoubtedly increases the complexity of the operation. Patients may have different understandings, leading to inaccurate sampling. Relying solely on the patient's self-control greatly increases the possibility of human error, thus affecting the consistency of diagnostic results. This sampling method is particularly inadequate for elderly, children, or patients with mobility difficulties. Secondly, during the "three-glass test," patients need to collect the first, middle, and last portions of urine in three separate containers to observe changes in urine color and parameters such as red blood cells and white blood cells. This test is one of the commonly used examination methods for the urinary system and is often used to determine the source and location of lesions in urinary system bleeding or inflammation. However, the segmented urination procedure is extremely complex, requiring patients to stop and restart urination multiple times. This not only increases the difficulty of the procedure but may also have a series of negative effects on human health. Fragmented urination can cause urine to reflux into the bladder or upstream urinary tract, increasing the risk of urinary tract infections such as urethritis and cystitis. Holding urine for extended periods can also allow bacteria to multiply in the bladder, further aggravating the possibility of infection. In addition, frequent fragmented urination keeps the bladder under high pressure for a long time, which may lead to bladder muscle fatigue, thinning of the bladder wall, and even affect the normal contraction function of the bladder. Urine reflux may also damage the kidneys, such as causing kidney diseases like pyelonephritis. For men, frequent fragmented urination may also increase the risk of prostatitis. In addition, traditional urine collection methods also pose hygiene and safety issues. When patients pour urine from a measuring cup into a test tube or container, urine is very likely to splash or leak, which not only affects environmental hygiene but may also pose a risk of cross-infection. Summary of the Invention

[0003] The purpose of this invention is to provide a urine sampling and testing component for urology, in order to solve the problems of inaccurate sampling, safety hazards, and hygiene issues in the prior art.

[0005] Preferably, the top of the outer wall of the converter is provided with a first flow groove, a second flow groove, a third flow groove and a fourth flow groove at equal intervals along the circumference. The position of the bottom end of the inner cavity of the first flow groove corresponds to the position of the top end of the conversion mechanism located on the front side. The bottom ends of the inner cavities of the second flow groove, the third flow groove and the fourth flow groove are connected to the bottom end of the inner cavity of the first flow groove. The position of the top end of the inner cavity of the first flow groove corresponds to the position of the urine tube.

[0006] Preferably, for mounting the test tube, the conversion mechanism includes: a support base, the top of the outer wall of the support base being disposed within the inner cavity of the fixing frame, and the top of the support base having several through-holes equidistantly spaced along the circumference; several guide rods, the tops of the outer walls of the guide rods being slidably embedded in the inner cavity of the support base equidistantly along the circumference, and the bottom ends of the guide rods slidably extending out of the bottom end of the support base; the top of the mounting base being disposed at the bottom end of the guide rods, and the middle of the outer wall of the mounting base having compression grooves on both the left and right sides, the bottom end of the mounting base extending out of the bottom end of the outer shell, and the test tube being screwed to the bottom end of the mounting base.

[0007] Preferably, in order to cause the rotating rod to drive the converter to rotate, the conversion mechanism further includes: two sliding columns, which are respectively set on the left and right sides of the top of the outer wall of the mounting base; a spring embedded in the inner cavity of the extrusion groove, with one end of the spring engaged with the inner wall of the extrusion groove; a portion of the retaining ball embedded in the inner cavity of the extrusion groove, with the other end of the spring engaged with the outer wall of the retaining ball; a rotating cylinder slidably and rotatably sleeved on the outer wall of the mounting base, the outer wall of the rotating cylinder being rotatably set at the bottom of the housing, and two drive grooves being equidistantly opened on the inner wall of the rotating cylinder along the circumference; two sliding columns being slidably fitted into the top of the inner cavity of the two drive grooves respectively; retaining grooves being opened on the bottom of the left and right sides of the inner wall of the rotating cylinder; and a gear sleeved on the top of the outer wall of the rotating cylinder and locked, with the gear on the front side meshing with the toothed gear.

[0008] Preferably, in order to seal the inner cavity of the test tube, the conversion mechanism further includes: a limiting rod, the top of the outer wall of the limiting rod being slidably fitted into the inner cavity of the support base, the bottom end of the limiting rod being slidably extended out of the bottom end of the support base and through the inner cavity of the mounting base, extending out of the bottom end of the mounting base; a float ball is disposed at the bottom end of the limiting rod, and there is a gap between the float ball and the bottom end of the mounting base.

[0011] Preferably, the included angle between the top and bottom of the drive groove is 90 degrees.

[0012] The present invention provides a urine sampling and testing component for urology, which has the following advantages: 1. The present invention receives urine through a first funnel and a urine tube, and discharges it into the inner cavity of a first flow channel, a second flow channel, a third flow channel, or a fourth flow channel. Thus, the urine is discharged into the inner cavity of three test tubes and a discharge tube through the first flow channel, the second flow channel, the third flow channel, and the fourth flow channel, respectively. The test tubes can collect the initial, middle, and final portions of urine, and the discharge tube can discharge excess urine.

[0013] 2. When the test tube receives a certain amount of urine, the weight of the test tube will increase, which will cause the mounting base to move downward. The downward movement of the mounting base, in conjunction with the sliding column and the drive groove, will cause the rotating cylinder to rotate. The rotation of the rotating cylinder will drive the gear to rotate, and the rotation of the gear will drive the rotating rod and the converter to rotate through the toothed gear. This will allow the positions of the first flow groove, the second flow groove, the third flow groove and the fourth flow groove to be switched with the urine tube, and the support base corresponding to the bottom position of the first flow groove will be switched.

[0014] 3. This device can automatically separate urine into first, middle, and last segments and directly introduce them into corresponding test tubes. This not only eliminates the complexity and human error of patients urinating in segments themselves, but also avoids the risk of urine backflow and potential health damage to the bladder and kidneys caused by segmented urination. At the same time, the device reduces splashing and leakage during urine transfer, effectively reducing the risk of cross-infection. It provides a more reliable and safe urine sample for clinical diagnosis in urology, ensuring the consistency and accuracy of diagnostic results. Attached Figure Description

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figures 1-10 This invention provides a technical solution for a urine sampling and testing component in urology, comprising: a shell 1, a urine tube 2, a first funnel 3, a conversion mechanism 4, a rotating rod 5, a toothed gear 6, a converter 7, a first flow channel 8, a second flow channel 9, a third flow channel 10, a fourth flow channel 11, a discharge pipe 12, a second funnel 13, a test tube 14, and a fixing frame 15. The urine tube 2 is disposed on the top of the outer wall of the shell 1, and the inner cavity of the urine tube 2 is connected to the inner cavity of the shell 1. The first funnel 3 is disposed at the top of the urine tube 2. The first funnel 3 is used to receive urine. There are three conversion mechanisms 4, all of which are located at the bottom of the inner cavity of the outer shell 1. The bottom of the conversion mechanism 4 extends out of the bottom of the outer shell 1. The conversion mechanism 4 is used to switch the flow direction of urine. The bottom of the rotating rod 5 is rotatably located at the middle of the bottom of the inner cavity of the outer shell 1. The toothed gear 6 is sleeved on the bottom of the outer wall of the rotating rod 5 and locked. The bottom of the converter 7 is located at the top of the rotating rod 5. The converter 7 is slidably embedded in the inner cavity of the outer shell 1.

[0019] More specifically, the top of the outer wall of the converter 7 is provided with a first flow groove 8, a second flow groove 9, a third flow groove 10, and a fourth flow groove 11 equidistantly spaced along the circumference. The bottom of the inner cavity of the first flow groove 8 corresponds to the top of the conversion mechanism 4 located on the front side. The bottom of the inner cavities of the second flow groove 9, the third flow groove 10, and the fourth flow groove 11 are connected to the bottom of the inner cavity of the first flow groove 8. The top of the inner cavity of the first flow groove 8 corresponds to the position of the urine tube 2. The converter 7 is used to switch the delivery of urine to the inner cavities of different test tubes 14. The discharge tube 1 2 is located at the bottom of the inner cavity of the outer shell 1. The bottom end of the discharge pipe 12 extends out of the bottom end of the outer shell 1. The discharge pipe 12 is used to discharge excess urine. The test tube 14 is screwed to the bottom end of the conversion mechanism 4. The test tube 14 is used for urine sampling. There are four fixing frames 15. The four fixing frames 15 are respectively set at equal intervals along the circumference at the bottom of the inner cavity of the outer shell 1. The three conversion mechanisms 4 and the discharge pipe 12 are all set in the inner cavity of the fixing frame 15. The fixing frame 15 is used to fix the support base 41. The second funnel 13 is set at the top end of the discharge pipe 12.

[0020] As a preferred embodiment, the conversion mechanism 4 further includes: a support base 41, urine leakage grooves 42, guide rods 43, mounting base 44, squeezing grooves 45, sliding columns 46, springs 47, retaining balls 48, limiting rods 49, floats 410, rotating cylinders 411, retaining grooves 412, driving grooves 413, and gears 414. The top of the outer wall of the support base 41 is located within the inner cavity of the fixing frame 15. Several urine leakage grooves 42 are equidistantly spaced along the circumference at the top of the support base 41. A second funnel 13 is provided at the top of the support base 41. The support base 41 is used to receive urine and limit the mounting base 44. Several guide rods 43 are provided, with their tops equidistantly spaced along the circumference and slidably embedded within the inner cavity of the support base 41. The bottom end of the support base 41 extends slidably from the bottom end of the 3. The guide rod 43 is used to limit the mounting base 44. The top end of the mounting base 44 is set at the bottom end of the guide rod 43. The middle of the outer wall of the mounting base 44 is provided with extrusion grooves 45 on both the left and right sides. The bottom end of the mounting base 44 extends from the bottom end of the outer shell 1. The test tube 14 is screwed to the bottom end of the mounting base 44. The mounting base 44 is used to install the test tube 14. There are two sliding pillars 46. The two sliding pillars 46 are respectively set on the left and right sides of the top end of the outer wall of the mounting base 44. The downward movement of the sliding pillars 46 and their cooperation with the drive groove 413 can cause the rotating cylinder 411 to rotate. The spring 47 is embedded in the inner cavity of the extrusion groove 45. One end of the spring 47 is clamped to the inner wall of the extrusion groove 45. The spring 47 is a rotational spring. When subjected to external force or After being stretched, the ball undergoes elastic deformation and returns to its initial state after the external force is removed. Spring 47 is used to push the ball 48 into the inner cavity of the slot 412. A portion of the ball 48 is embedded in the inner cavity of the compression groove 45. The other end of spring 47 is engaged with the outer wall of the ball 48. Spring 47, ball 48, and slot 412 are used to fix the mounting base 44. The length of the ball 48 extending into the inner cavity of the slot 412 is less than its radius, ensuring that the ball 48 can disengage from the inner cavity of the slot 412. Rotary cylinder 411 is slidably and rotatably sleeved on the outer wall of the mounting base 44. The outer wall of rotary cylinder 411 is rotatably located at the bottom end of the outer shell 1. Two drive grooves 413 are equidistantly spaced along the circumferential direction on the inner wall of rotary cylinder 411. Two sliding pillars 46 can slide... The movable mating fitting is inserted into the top of the inner cavity of the two drive slots 413. The included angle between the top and bottom of the drive slots 413 is 90 degrees, ensuring that the rotating cylinder 411 can rotate 90 degrees. The bottom of the left and right sides of the inner wall of the rotating cylinder 411 is provided with a slot 412. The other part of the two locking balls 48 extends into the inner cavity of the two slots 412 respectively. The gear 414 is sleeved on the top of the outer wall of the rotating cylinder 411 and locked. The gear 414 located on the front side meshes with the toothed gear 6. The gear 414 is used to cooperate with the toothed gear 6 to cause the rotating rod 5 to drive the converter 7 to rotate. The top of the outer wall of the limiting rod 49 is slidably mating into the inner cavity of the support base 41. The bottom end of the limiting rod 49 slidably extends out of the bottom end of the support base 41 and passes through the inner cavity of the mounting base 44.The bottom end of the mounting base 44 extends outwards, and a float 410 is disposed at the bottom end of the limiting rod 49. A gap exists between the float 410 and the bottom end of the mounting base 44, and the float 410 is used to seal the inner cavity of the test tube 14.

[0021] The working process of the conversion mechanism 4 works in coordination with the urine segmentation logic of the overall device: In the initial state, the locking ball 48 is inserted into the locking slot 412, the mounting base 44 remains in position, and the test tube 14 is in the state of waiting to collect urine; after the urine flows into the support base 41 through the converter 7, it enters the test tube 14 through the urine leakage groove 42. As the urine collection volume increases, the test tube 14 becomes heavier and pushes the mounting base 44 to slide downward. The locking ball 48 is released from the locking slot 412, and the sliding column 46 slides along the drive groove 413 to drive the rotating cylinder 411 and the gear 414 to rotate. Then, the toothed gear 6 drives the converter 7 to switch the flow groove, completes the sample sealing of the current test tube and prepares the urine collection for the next test tube, and finally realizes the automatic segmented collection and sealing of the first, middle and last segments of urine.

[0022] The working principle includes the following steps: Step 1: When using the device, the patient urinates into the first funnel 3. The discharged urine flows through the first funnel 3 and the urine tube 2 into the inner cavity of the outer shell 1. Since the position of the urine tube 2 corresponds to the position of the first flow channel 8, the urine flowing through the urine tube 2 will flow into the inner cavity of the first flow channel 8. The urine will then flow through the first flow channel 8 to the top of the support 41, which corresponds to the bottom of the inner cavity of the first flow channel 8. The urine flowing to the top of the support 41 will flow downward through the urine leakage channel 42 and drip onto the top of the mounting base 44, and then flow into the inner cavity of the test tube 14 through the inner cavity of the mounting base 44. Step 2: As the urine level in the inner cavity of test tube 14 rises, the weight of test tube 14 increases. When the urine in the inner cavity of test tube 14 comes into contact with the float 410, the float 410 moves upward with the rising urine level due to buoyancy, until the bottom of the inner cavity of the mounting base 44 is sealed by the float 410. At this time, the weight of test tube 14 and urine pulls the mounting base 44 downward. The downward movement of the mounting base 44, under the action of the slot 412, squeezes the retaining ball 48 into the inner cavity of the squeezing groove 45, and squeezes the spring 47 to undergo elastic deformation, until the retaining ball 48 is completely disengaged from the inner cavity of the slot 412. At the same time, the downward movement of the mounting base 44 drives the sliding column 46 downward. The sliding column 46 slides downward along the inner cavity of the drive groove 413. Meanwhile, due to the interaction between the guide rod 43 and the support base 41, the mounting base 44 continues to move downward. The limiting position of the mounting seat 44, and then the downward sliding column 46 and the drive groove 413 will cause the rotating cylinder 411 to drive the gear 414 on its outer wall to rotate counterclockwise. The counterclockwise rotation of the gear 414 on the front side will cause the toothless gear 6 to drive the converter 7 to rotate clockwise through the rotating rod 5 until the sliding column 46 slides to the bottom of the inner cavity of the drive groove 413. At this time, the rotating cylinder 411 drives the gear 414 to rotate 90 degrees counterclockwise. At the same time, under the drive of the toothless gear 6, the converter 7 is driven to rotate 90 degrees clockwise through the rotating rod 5. At this time, the bottom of the inner cavity of the first flow groove 8 corresponds to the top of the support seat 41 on the left side. Furthermore, the toothless gear 6 separates from the gear 414 on the front side and meshes with the gear 414 on the left side. At the same time, the top of the inner cavity of the second flow groove 9 corresponds to the position of the urinary tube 2. Step 3: At this point, the patient continues to urinate. Urine flows through the first funnel 3, the urinary catheter 2, the second flow channel 9, the leakage channel 42 on the left side, and the inner cavity of the mounting base 44 on the left side into the inner cavity of the test tube 14 on the left side. This process repeats, causing the bottom of the inner cavity of the first flow channel 8 to correspond to the top of the support base 41 on the rear side, and causing the top of the inner cavity of the third flow channel 10 to correspond to the position of the urinary catheter 2. This allows the test tube 14 on the rear side to receive urine. This process repeats until the test tube 14 on the rear side has finished receiving urine. Then, the bottom of the inner cavity of the first flow channel 8 will correspond to the top of the discharge tube 12. The urine that the patient continues to urinate will then be discharged through the fourth flow channel 11 into the inner cavity of the discharge tube 12 and discharged out through the discharge tube 12. Thus, the front, middle, and rear sections of urine are sampled through the three test tubes 14.

[0023] In summary, this device can automatically separate urine into the first, middle, and last segments and directly introduce them into the corresponding test tubes. This not only eliminates the complexity and human error of patients manually separating urine segments, but also avoids the risk of urine reflux and potential health damage to the bladder and kidneys caused by segmented urination. At the same time, the device reduces splashing and leakage during urine transfer, effectively reducing the risk of cross-infection. It provides a more reliable and safe urine sample for clinical diagnosis in urology, ensuring the consistency and accuracy of diagnostic results.
