Description

Technical Field

[0001] This invention relates to the field of urine sampling technology, and more specifically to a urine sampler. Background Technology

[0002] Urine testing, as one of the most common diagnostic methods in clinical practice, provides a wealth of information about a person's health. It is used not only to detect diseases of the urinary system but also to provide crucial data for the diagnosis and treatment evaluation of various internal medicine conditions such as diabetes, liver disease, and kidney disease. Therefore, accurate urine sample collection is essential to ensuring the accuracy of subsequent analysis results.

[0003] When performing urine tests, it is generally recommended to collect midstream urine (also known as clean-up midstream urine) because the initial stream of urine may contain bacteria, cells, and other impurities from outside the urethra or the urethral opening itself. These substances may interfere with the results of urine analysis, leading to misdiagnosis or inaccurate results.

[0004] Specifically, the reasons for collecting midstream urine are as follows: Reduce contamination: As the initial stream of urine flows through the urethral opening, it may carry away bacteria, cell debris, or other contaminants from the skin and surrounding urethra. Using such samples directly for testing can lead to false positives, especially in diagnosing conditions such as urinary tract infections.

[0005] Improved accuracy: Midstream urine is relatively "cleaner" and better reflects the actual condition of the urinary system. This is crucial for chemical analysis, microscopic examination, and pathogen culture, as it reduces the influence of external factors on the results.

[0006] Ensure representativeness: Midstream urine is more representative of the overall state of urine in the bladder, rather than just the localized area near the urethral opening. This helps doctors make a more accurate diagnosis.

[0007] To ensure proper midstream urine collection, it is generally recommended that patients wash their hands and the urethral area before urinating. Urine sample collection should begin some time after the urine flow has started (usually a few seconds) and should be stopped before the flow ends. This method maximizes the purity of the collected urine sample and the effectiveness of the test.

[0008] Existing urine sampling equipment often cannot sample midstream urine separately, which can easily lead to inaccurate urine test results, affecting doctors' judgment of patients' conditions. Furthermore, it is more troublesome for some patients with mobility difficulties or who cannot control their urination to collect midstream urine, as urine is prone to spillage.

[0009] Therefore, a urine sampler is needed to solve the above problems. Summary of the Invention

[0010] To address the aforementioned problem—namely, the difficulty in obtaining midstream urine from patients with mobility difficulties and loss of urination control—this invention provides a urine sampler.

[0011] A urine sampler includes a receiving mechanism comprising a cylindrical body with a first liquid chamber and a tail liquid chamber on the upper side of the first liquid chamber. The top wall of the tail liquid chamber has an opening communicating with an external space. A sliding hole connects the tail liquid chamber and the first liquid chamber. A middle section mechanism is provided between the sliding hole and the opening. The middle section mechanism includes a middle section cylinder slidably disposed in the sliding hole. The top of the middle section cylinder is open, and six through holes are evenly distributed along the circumference at the bottom of the middle section cylinder. An opening / closing member is provided at the bottom of the middle section cylinder to close the through holes, which are located in the tail liquid chamber. Six drain holes are evenly distributed along the circumference at the upper part of the middle section cylinder. A sealing ring is fixedly connected to the top of the cylindrical body to close the drain holes.

[0012] Specifically, in the initial state, the sealing ring closes the drain hole, and the opening and closing component opens the through hole. When in use, when the user collects urine, the urine flows into the middle section tube through the opening at the top of the middle section tube. The urine flows into the first liquid chamber through the through hole at the bottom of the middle section tube. After a portion of the first urine has flowed in, the middle section tube slides downward, the opening and closing component closes the through hole, and at the same time, the drain hole slides away from the sealing ring, causing the drain hole to open. Then, the middle section of urine flows into the middle section tube. When the liquid level in the middle section tube reaches the drain hole, the subsequent urine flows into the tail liquid chamber through the drain hole.

[0013] The design of the mid-section tube and the through-hole allows the first segment of urine to enter the first fluid chamber through the through-hole and be discharged. Then, through the design of the opening and closing device and the sliding hole, when the urine reaches the mid-section, the opening and closing device closes the through-hole, allowing the mid-section urine to enter the mid-section tube and be stored in the mid-section tube. At the same time, the drain hole opens. After the mid-section urine collection is completed, the last segment of urine enters the last fluid chamber through the drain hole, thereby realizing the collection of mid-section urine. This allows the last segment of urine in patients with difficulty in urinary control to be stored and prevents the last segment of urine from spilling.

[0014] Preferably, the opening and closing component includes a closed cylinder fixedly connected to the bottom wall of the first liquid chamber, the inner diameter of the closed cylinder being the same as the outer diameter of the bottom end of the middle section cylinder, and the closed cylinder being coaxial with the middle section cylinder.

[0015] Preferably, a sliding mechanism is provided in the first liquid chamber. The sliding mechanism includes an elastic element, which includes a fixing ring fixedly sleeved at the bottom of the middle section cylinder. A first spring is connected between the fixing ring and the bottom wall of the first liquid chamber, and a locking element is provided between the fixing ring and the top wall of the first liquid chamber.

[0016] Specifically, during use, when the closing ring closes the drain hole, the locking element locks the fixing ring, and the first spring is in a stretched state; when the middle section cylinder needs to slide downward, the locking element unlocks the fixing ring, and the fixing ring moves downward under the tension of the first spring, while the fixing ring drives the middle section cylinder to slide downward, so that the middle section cylinder enters the closed cylinder.

[0017] By setting up the elastic element, when the middle section cylinder needs to move downward, it can move downward under the tension of the first spring, thereby causing the sealing cylinder to seal the through hole at the bottom of the middle section cylinder.

[0018] Preferably, two locking members are symmetrically arranged between the fixing ring and the top wall of the first liquid chamber. Each locking member includes an installation groove formed in the top wall of the first liquid chamber, a fixing rod disposed in the installation groove, the fixing rod being fixedly connected to the fixing ring, and an embedding groove formed in the fixing rod with an opening away from the axis of the middle section cylinder. A slider is slidably connected in the embedding groove, and a second spring is connected between the slider and the embedding groove. The bottom surface of the second spring away from the middle section cylinder is inclined, and a magnetic block is fixedly connected in the installation groove. The magnetic block is magnetically attracted to the slider.

[0019] Specifically, in use, when the locking component needs to unlock the fixing ring, the slider is moved so that it disengages from the magnet and enters the embedding groove, compressing the second spring. At this time, the slider is no longer restricted by the magnet, thus the fixing ring is not restricted and can move downward under the tension of the first spring.

[0020] By setting a locking device, the fixing ring can be kept in a certain position, so that the first urine segment can be collected separately, thereby separating the first urine segment from the middle urine segment.

[0021] Preferably, the sliding mechanism further includes a trigger, which includes a sliding ring slidably connected in the first liquid chamber. A third spring is connected between the sliding ring and the bottom wall of the first liquid chamber. Two abutment rods are symmetrically fixedly connected to the top of the sliding ring, and the abutment rods can abut against the inclined surface of the slider.

[0022] Specifically, during use, when the first stream of urine enters the first liquid chamber, as the liquid level rises, the sliding ring moves upward under the action of liquid buoyancy. The sliding ring drives the abutment rod to move upward, and the top of the abutment rod abuts against the inclined surface of the slider, causing the slider to disengage from the magnetic block. The slider also compresses the second spring, causing the locking device to unlock.

[0023] By setting the trigger, the sliding ring can be pushed upward as the first segment of urine is collected, thereby causing the sliding ring to drive the abutment rod to unlock the locking device, which in turn causes the middle segment cylinder to move downward to collect the middle segment of urine.

[0024] Preferably, the elastic element further includes a reset rod fixedly connected to the bottom surface of the middle section cylinder, and a reset hole is provided on the bottom wall of the first liquid chamber, and the reset rod is slidably connected in the reset hole.

[0025] Specifically, when the middle section of the cylinder needs to be reset, push the reset rod upwards, and the reset rod will cause the middle section of the cylinder to reset upwards.

[0026] Furthermore, the sliding ring is made of foam material.

[0027] Preferably, two C-shaped handles are symmetrically arranged on the outer circumference of the cylinder.

[0028] The handle design makes it easy for users to hold the sampler.

[0029] Preferably, the diameter of the top section of the middle section is larger than the diameter of the bottom section, and the middle section of the middle section is shaped like an inverted frustum.

[0030] The design of the top section of the middle tube having a larger diameter than the bottom section makes it easier for users to pour urine into the middle tube.

[0031] Preferably, the top of the cylinder is provided with a sealing cover, the sealing cover is detachably connected to the top of the cylinder, and the opening is formed on the sealing cover.

[0032] Specifically, when using the product, after collection, if it is necessary to drain the tail urine, remove the sealing cap from the cylinder and drain the tail urine from the tail fluid chamber.

[0033] Furthermore, a discharge hole is provided on the bottom wall of the first liquid chamber, the discharge hole is connected to the external space, and a sealing block is detachably connected to the discharge hole.

[0034] Specifically, after the collection is completed, when it is necessary to drain the first segment of urine, the sealing block is removed from the drain hole, and the first segment of urine is drained from the first fluid chamber.

[0035] The beneficial effects of this invention are as follows: 1. The design of the mid-section tube and through-hole allows the first segment of urine to enter the first fluid chamber through the through-hole and be discharged. Then, through the design of the opening and closing device and the sliding hole, when the urine reaches the mid-section, the opening and closing device closes the through-hole, allowing the mid-section urine to enter the mid-section tube and be stored in the mid-section tube. At the same time, the drain hole opens. After the mid-section urine collection is completed, the last segment of urine enters the last fluid chamber through the drain hole, thereby realizing the collection of mid-section urine. This allows the last segment of urine in patients with difficulty in urinary control to be stored and prevents the last segment of urine from spilling.

[0036] 2. By setting up the closed tube, when the middle tube slides down, the closed tube can close the through hole and store the middle urine in the middle tube.

[0037] 3. The elastic element allows the middle section cylinder to move downwards under the tension of the first spring when needed, thus sealing the through hole at the bottom of the middle section cylinder. The locking element holds the fixing ring in a specific position, allowing for separate collection of the first urine segment, thus separating it from the middle urine segment. The trigger element pushes the sliding ring upwards as the first urine segment is collected, causing the sliding ring to drive the abutment rod to unlock the locking element, allowing the middle section cylinder to move downwards for collection of the middle urine segment.

[0040] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0041] like Figure 1 , 2 As shown in Figure 3, an embodiment of the present invention discloses a urine sampler, including a receiving mechanism 1. The receiving mechanism 1 includes a cylindrical body 11, in which a first liquid chamber 12 is formed. A tail liquid chamber 13 is formed on the upper side of the first liquid chamber 12. An opening 14 is formed on the top wall of the tail liquid chamber 13, and the opening 14 communicates with the external space. A sliding hole 15 is provided between the tail liquid chamber 13 and the first liquid chamber 12. A middle section mechanism 2 is provided between the sliding hole 15 and the opening 14. The middle section mechanism 2 includes a sliding device. A middle section cylinder 21 is placed in the sliding hole 15. The top end of the middle section cylinder 21 is open. Six through holes 22 are evenly opened along the circumferential direction at the bottom of the middle section cylinder 21. An opening and closing member 23 is provided at the bottom of the middle section cylinder 21, which closes the through holes 22. The through holes 22 are located in the tail liquid chamber 13. Six drain holes 24 are evenly opened along the circumferential direction at the upper part of the middle section cylinder 21. A sealing ring 25 is fixedly connected to the top end of the cylinder body 11, which closes the drain holes 24.

[0042] Specifically, in the initial state, the sealing ring 25 closes the drain hole 24, and the opening and closing component 23 opens the through hole 22. When in use, when the user collects urine, the urine flows into the middle section cylinder 21 through the opening at the top of the middle section cylinder 21, and the urine flows into the first liquid chamber 12 through the through hole 22 at the bottom of the middle section cylinder 21. After a portion of the first urine has flowed in, the middle section cylinder 21 slides downward, the opening and closing component 23 closes the through hole 22, and at the same time, the drain hole 24 slides away from the sealing ring 25, so that the drain hole 24 opens. Then, the middle section of urine flows into the middle section cylinder 21. When the liquid level in the middle section cylinder 21 reaches the drain hole 24, the subsequent urine flows into the tail liquid chamber 13 through the drain hole 24.

[0043] The design of the intermediate tube 21 and the through hole 22 allows the first segment of urine to enter the first liquid chamber 12 through the through hole 22 and be discharged. Then, the design of the opening and closing part 23 and the sliding hole 15 allows the opening and closing part 23 to close the through hole 22 when the urine reaches the middle segment, allowing the middle segment of urine to enter the intermediate tube 21 and be stored in the intermediate tube 21. At the same time, the drain hole 24 is opened. After the middle segment of urine is collected, the last segment of urine enters the last liquid chamber 13 through the drain hole 24, thereby realizing the collection of the middle segment of urine. This allows the last segment of urine of patients with difficulty in urinary control to be stored and prevents the last segment of urine from spilling.

[0044] like Figure 3 , 6As shown, the opening and closing component 23 includes a closed cylinder 231 fixedly connected to the bottom wall of the first liquid chamber 12. The inner diameter of the closed cylinder 231 is the same as the outer diameter of the bottom end of the middle section cylinder 21, and the closed cylinder 231 is coaxial with the middle section cylinder 21.

[0045] Specifically, during use, when the middle section cylinder 21 slides downward, the middle section cylinder 21 slides into the closed cylinder 231, and the closed cylinder 231 seals the through hole 22.

[0046] By setting the sealing cylinder 231, when the middle section cylinder 21 slides downward, the sealing cylinder 231 can close the through hole 22 and store the middle section urine in the middle section cylinder 21.

[0047] like Figure 3 , 6 As shown, a sliding mechanism 3 is provided in the first liquid chamber 12. The sliding mechanism 3 includes an elastic element 31. The elastic element 31 includes a fixing ring 311 fixedly sleeved at the bottom of the middle section cylinder 21. A first spring 312 is connected between the fixing ring 311 and the bottom wall of the first liquid chamber 12. A locking element 32 is provided between the fixing ring 311 and the top wall of the first liquid chamber 12.

[0048] Specifically, during use, when the closing ring 25 closes the drain hole 24, the locking member 32 locks the fixing ring 311, and the first spring 312 is in a stretched state; when the middle section cylinder 21 needs to slide downward, the locking member 32 unlocks the fixing ring 311, and the fixing ring 311 moves downward under the tension of the first spring 312. At the same time, the fixing ring 311 drives the middle section cylinder 21 to slide downward, so that the middle section cylinder 21 enters the closed cylinder 231.

[0049] By setting the elastic element 31, when the middle section cylinder 21 needs to move downward, the middle section cylinder 21 can move downward under the pulling force of the first spring 312, so that the closing cylinder 231 closes the through hole 22 at the bottom of the middle section cylinder 21.

[0050] like Figure 4 , 8As shown, two locking members 32 are symmetrically arranged between the fixing ring 311 and the top wall of the first liquid chamber 12. Each locking member 32 includes an installation groove 321 formed in the top wall of the first liquid chamber 12. A fixing rod 322 is provided in the installation groove 321. The fixing rod 322 is fixedly connected to the fixing ring 311. An embedding groove 323 with an opening away from the axis of the middle section cylinder 21 is formed in the fixing rod 322. A slider 324 is slidably connected in the embedding groove 323. A second spring 325 is connected between the slider 324 and the embedding groove 323. The bottom surface of the second spring 325 away from the middle section cylinder 21 is inclined. A magnetic block 326 is fixedly connected in the installation groove 321. The magnetic block 326 is magnetically attracted to the slider 324.

[0051] Specifically, in use, when the locking member 32 needs to unlock the fixing ring 311, the slider 324 is moved so that the slider 324 disengages from the magnet 326 and enters the embedding groove 323, compressing the second spring 325. At this time, the slider 324 is not restricted by the magnet 326, so that the fixing ring 311 is not restricted, allowing the fixing ring 311 to move downward under the pulling force of the first spring 312.

[0052] By setting the locking element 32, the fixing ring 311 can be held in a certain position, so that the first urine segment can be collected separately, thereby separating the first urine segment from the middle urine segment.

[0053] like Figure 4 , 6 As shown, the sliding mechanism 3 also includes a trigger 33, which includes a sliding ring 331 slidably connected in the first liquid chamber 12. A third spring 332 is connected between the sliding ring 331 and the bottom wall of the first liquid chamber 12. Two abutment rods 333 are symmetrically fixedly connected to the top of the sliding ring 331. The abutment rods 333 can abut against the inclined surface of the slider 324.

[0054] Specifically, during use, when the first stream of urine enters the first liquid chamber 12, as the liquid level rises, the sliding ring 331 moves upward under the action of liquid buoyancy. The sliding ring 331 drives the abutment rod 333 to move upward. The top of the abutment rod 333 abuts against the inclined surface of the slider 324, causing the slider 324 to disengage from the magnetic block 326. The slider 324 compresses the second spring 325, thereby unlocking the locking member 32.

[0055] By setting the trigger 33, the sliding ring 331 can be pushed upward as the first segment of urine is collected, thereby causing the sliding ring 331 to drive the abutment rod 333 to unlock the locking member 32, thereby causing the middle section cylinder 21 to move downward to collect the middle segment of urine.

[0056] like Figure 3 As shown, the elastic member 31 also includes a reset rod 313 fixedly connected to the bottom surface of the middle section cylinder 21, and a reset hole 314 is provided on the bottom wall of the first liquid chamber 12, and the reset rod 313 is slidably connected in the reset hole 314.

[0057] Specifically, when the middle section cylinder 21 needs to be reset, push the reset rod 313 upward, and the reset rod 313 will drive the middle section cylinder 21 to reset upward.

[0058] Furthermore, the sliding ring 331 is made of foam material.

[0059] like Figure 1 As shown, two C-shaped handles 4 are symmetrically arranged on the outer circumference of the cylinder 11.

[0060] The design of handle 4 makes it convenient for users to hold the sampler.

[0061] like Figure 7 As shown, the diameter of the top section of the middle section cylinder 21 is larger than the diameter of the bottom section, and the middle section of the middle section cylinder 21 is inverted frustum shape.

[0062] The design of the top section of the middle section tube 21 having a larger diameter than the bottom section makes it easier for users to introduce urine into the middle section tube 21.

[0063] like Figure 3 As shown, a sealing cover 16 is provided at the top of the cylinder 11. The sealing cover 16 is detachably connected to the top of the cylinder 11, and the opening 14 is formed on the sealing cover 16.

[0064] Specifically, when using the product, after collection, if the tail urine needs to be discharged, remove the sealing cap 16 from the cylinder 11 and discharge the tail urine from the tail liquid chamber 13.

[0065] Furthermore, a discharge hole is provided on the bottom wall of the first liquid chamber 12, the discharge hole is connected to the external space, and a sealing block is detachably connected to the discharge hole.

[0066] Specifically, after the collection is completed, when the first segment of urine needs to be discharged, the sealing block is removed from the discharge hole, and the first segment of urine is discharged from the first liquid chamber 12.
