Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a urine sampling device. Background Art

[0002] In the field of modern medicine, urine detection is an extremely important detection method and plays an indispensable role. By analyzing the components in urine, it can accurately reflect the health status of the human urinary system, and at the same time provide key clues for the diagnosis, condition monitoring, and treatment effect evaluation of various systemic diseases such as diabetes, kidney disease, and liver disease. It is a commonly used and important detection method in clinical diagnosis, disease screening, and health management.

[0003] Currently, urine cups are mostly used for urine sampling. During the detection, the patient first urinates into the urine cup and then hands it over to the medical staff; the medical staff then pours the urine in the urine cup into a test tube, and the test tube becomes the sample container for subsequent detection; then, a test strip is taken out and immersed in the test tube. After the immersion is completed, the test strip is taken out, and the excess urine is blotted with absorbent paper. Finally, the test strip is put into a urine analyzer for inspection and analysis.

[0004] However, the existing urine sampling devices have many obvious drawbacks. In the sampling process, the spraying of urine from the human genitals is uncontrollable, and the urine is extremely likely to splash outside the urine cup and then adhere to the patient's hands, which is not only unhygienic but also may cause cross-infection. During the process of transferring urine to the test tube, the urine is directly exposed to the air, and the emitted odor will have an adverse impact on the surrounding environment and medical staff. Moreover, the transfer operation increases the risk of urine splashing, which not only pollutes the detection environment but also greatly increases the cleaning difficulty. In addition, the timing of urination to obtain midstream urine mainly depends on the patient's self-judgment, resulting in a rather high sampling difficulty, and it is very difficult to ensure that ideal midstream urine can be collected every time. Not only that, the entire operation process is complicated and inefficient, and it cannot meet the clinical requirements for rapid and accurate detection. Summary of the Invention

[0005] The present invention aims to provide a urine sampling device to solve the problems of urine splashing, odor emission, high sampling difficulty, and cumbersome operation process during urine sampling by the existing devices.

[0006] To achieve the above object, the present invention adopts the following technical solution: a urine sampling device, including a sampling unit and a collection unit. The sampling unit includes a receiving cylinder, and a partition is fixedly connected inside the receiving cylinder. The partition divides the receiving cylinder into upper and lower chambers. A through hole for communicating the upper and lower chambers is provided on the partition, and a blocking unit capable of automatically blocking the through hole is provided in the lower chamber; the collection unit includes a vacuum tube, the vacuum tube is detachably connected to one side of the upper chamber close to the partition, a first cover is fixedly connected to the vacuum tube, and a detection unit is slidably arranged on the first cover. A test strip is placed in the detection unit, and the urine in the vacuum tube can enter the detection unit and soak the test strip.

[0007] The beneficial effects of this solution are as follows: When performing urine sampling, first connect the vacuum tube to the receiving cylinder. The patient holds the vacuum tube and discharges urine into the receiving cylinder. After the urine flows into the upper chamber, it flows into the lower chamber through the through hole on the partition. As the urine in the lower chamber accumulates continuously, when the set initial urine volume is reached, the blocking unit will automatically block the through hole on the partition. At this time, the subsequent discharged midstream urine is intercepted in the upper chamber and gradually flows into the connected vacuum tube to complete the collection. When the vacuum tube is full of midstream urine, the remaining midstream urine and the downstream urine still remain in the upper chamber. After all urine collection work is completed, first pour out the urine in the receiving cylinder, then remove the vacuum tube from the receiving cylinder, and discard the receiving cylinder. Thus, the entire urine collection process is successfully completed.

[0008] When urine detection is required, press the detection unit to make the detection unit slide into the vacuum tube, so that the urine in the vacuum tube enters the detection unit and soaks the test strip. After the sampling is completed, take out the test strip, absorb the excess urine with absorbent paper, and finally put it into a urine analyzer for inspection and analysis.

[0009] Compared with the prior art, the advantages of this technical solution are:

[0010] (1) Solve the hidden danger of urine splashing: When performing urine sampling, the patient holds the vacuum tube and discharges urine into the receiving cylinder. During the whole process, the urine flows in the relatively closed receiving cylinder, completely eliminating the direct spraying of urine to the outside world from the source, thoroughly avoiding the situation that urine splashes outside the urine cup and adheres to the patient's hand, greatly reducing the risk of cross-infection, and effectively ensuring the hygiene and safety of the sampling process.

[0011] (2) Eliminate the trouble of odor emission: Since the urine is collected in the receiving cylinder and the vacuum tube throughout the process, abandoning the traditional step of pouring urine from the urine cup into the test tube, greatly reducing the time and links of urine exposure to the air, effectively avoiding the adverse impact of urine odor on the surrounding environment and medical staff, and creating a better air quality for the detection environment.

[0012] (3) Reduce the sampling difficulty coefficient: This technical solution is provided with a plugging unit for automatically plugging the through hole. When urine is discharged into the upper chamber and flows into the lower chamber through the through hole, when the urine volume in the lower chamber reaches the set initial urine volume, the plugging unit automatically starts to plug the through hole, so that the middle-section urine can be accurately collected in the upper chamber. There is no need for the patient to accurately judge the urination timing by himself, which significantly reduces the difficulty of collecting ideal middle-section urine, effectively improves the sample quality, and lays a reliable data foundation for subsequent detection.

[0013] (4) Simplify the operation process and improve the detection efficiency: Medical staff only need to connect the vacuum tube to the accommodating cylinder. After the patient finishes urinating, the vacuum tube can collect the middle-section urine, and then remove the vacuum tube to complete the collection work, without the need for complicated operations such as urine transfer in the traditional way. In the urine detection link, placing the test strip in the detection unit to soak is simple and easy to operate. This not only greatly reduces the operation steps, but also reduces the error risk caused by complex operations, fully meeting the urgent clinical needs for rapid and accurate detection.

[0014] (5) Enhance the convenience of the detection process: The vacuum tube and the accommodating cylinder are designed with a detachable connection. After the urine collection is completed, the accommodating cylinder can be directly discarded, and the vacuum tube can be used as an independent sample storage and detection container, which is convenient to carry and transport, further improving the convenience of the entire detection process.

[0015] In summary, the urine sampling device of the present invention, through the coordinated cooperation of various components, successfully solves the problems existing in the existing devices such as urine splashing, odor emission, sampling difficulty, and cumbersome process, and provides a new, convenient, efficient, and hygienic solution for urine detection.

[0016] Furthermore, the detection unit includes a collection tube, the collection tube is hermetically and slidably arranged on the first cover body, a liquid inlet hole is provided on the collection tube, the first cover body can seal the liquid inlet hole, a second cover body is detachably connected to the collection tube, and a clamping block is fixedly connected to the side of the second cover body close to the collection tube, and the clamping block is used for clamping the test strip.

[0017] The beneficial effects of this solution are as follows: Compared with the existing method of nurses dipping the test strip into the test tube during detection, this technical solution has the following advantages:

[0018] (1) Avoid test strip contamination: The collection tube acts as a barrier to effectively prevent external impurities, dust, etc. from falling into the vacuum tube and contaminating the urine sample. At the same time, it avoids the direct contact of the tester's fingers, etc. with the urine during operation, reducing the risk of cross-contamination, thereby ensuring the accuracy of the test results.

[0019] (2) Easy to operate: It is relatively simple to pre-place the test strip in the collection tube and then put the collection tube into the vacuum tube. This method is especially suitable for batch testing or testing in specific environments (such as the wild), reducing problems such as shaking and breaking that may occur when the test strip is directly inserted into the vacuum tube, and improving the detection efficiency and success rate.

[0020] (3) Compared with the existing sample dipping method (static sample dipping), this technical solution adopts the dynamic sample dipping method, that is, the test strip is pre-placed in the collection tube, and the urine in the vacuum tube flows into the collection tube through the liquid inlet hole to achieve dynamic sample dipping. The advantages of dynamic sample dipping are:

[0021] First, accelerate the reaction process: The dynamic urine enters the collection tube, enabling the test strip to contact the urine fully and quickly, shortening the detection waiting time and improving the detection efficiency. For example, when detecting glucose in urine, dynamic sample dipping can make glucose evenly distributed on the test strip, react evenly with the detection reagent, and obtain more accurate detection results.

[0022] Second, improve the detection sensitivity: During the dynamic sample dipping process, the urine continuously flows and updates the contact surface with the test strip, helping the substance to be detected to be more evenly distributed on the test strip, making the reaction more complete, being able to detect lower concentrations of the substance to be detected, and thus improving the detection sensitivity and reducing the possibility of missed detection.

[0023] Third, enhance the result accuracy: Dynamic sample dipping can make each part of the test strip contact the urine more evenly, avoiding the situation of too high or too low local concentration that may occur during static sample dipping, so that the detection result is more stable and accurate, reducing the result deviation caused by uneven sample dipping.

[0024] Fourth, promote mass exchange: During the dynamic sample dipping process, the urine continuously flows into the collection tube, forming a dynamic mass exchange process when contacting the test strip, enabling the substance to be detected to diffuse onto the test strip more efficiently, and even substances with extremely low concentrations have more opportunities to react with the detection reagent on the test strip.

[0025] Furthermore, a diversion tube is connected to the accommodating cylinder, and the diversion tube is connected to the upper chamber.

[0026] The beneficial effects of this solution are: The setting of the diversion tube greatly optimizes the sampling process and reduces the operation difficulty, which is particularly friendly to patients with limited mobility or physical discomfort, making the urine sampling process easier and more convenient. Moreover, compared with the direct impact of urine on the accommodating cylinder, the diversion tube can effectively disperse the impact force of urine, thereby reducing the risk of urine splashing when entering the accommodating cylinder, effectively ensuring the hygiene of the sampling environment, and reducing the potential risk of cross-infection caused by urine splashing.

[0027] Furthermore, the guide tube is trumpet-shaped, the small diameter end of the guide tube is connected to the accommodating tube, the large diameter end of the guide tube is fixedly connected to a collecting plate, the collecting plate is provided with a collecting groove, the collecting groove is provided with a connecting hole, and the connecting hole is connected to the inside of the guide tube.

[0028] The beneficial effects of this solution are: the trumpet-shaped diversion tube has a large opening area at the large diameter end, which greatly expands the urine collection range. Even if the patient deviates from the direction when urinating, it can more easily guide the urine, reduce urine spillage, and effectively improve the success rate of urine collection. The collection plate and collection trough on the periphery of the large diameter end of the diversion tube can further prevent urine splashing. When urine hits the collection plate, it will be collected by the collection trough to prevent urine from splashing into the surrounding environment, maintain the cleanliness of the sampling environment, and reduce the risk of cross infection. In addition, the connection hole on the collection trough is connected to the inside of the diversion tube to ensure that urine can flow smoothly into the holding tube. The entire design allows patients to operate more conveniently and smoothly during the sampling process.

[0029] Furthermore, the size of the connecting hole is smaller than the size of the large diameter end of the flow guide pipe.

[0030] The beneficial effect of this solution is that since the size of the connecting hole is smaller than the size of the large diameter end of the diversion tube, the urine entering the diversion tube can be prevented from splashing after the urine is discharged into the diversion tube.

[0031] Furthermore, the blocking unit includes a guide sleeve, which is fixedly connected in the lower chamber. A guide rod is slidably arranged in the guide sleeve. A blocking ball is fixedly connected to one end of the guide rod away from the guide sleeve. The blocking ball can block the through hole on the partition.

[0032] The beneficial effect of this solution is that as the amount of urine in the lower chamber gradually accumulates, when the set initial urine volume is reached, the buoyancy generated by the urine will act on the blocking ball. Thanks to the smooth sliding of the guide rod in the guide sleeve, the cooperation of the guide sleeve and the guide rod provides a stable guide path for the movement of the blocking ball, avoiding the offset or shaking of the blocking ball during movement, so that the blocking ball can move accurately along the direction of the guide rod to the through hole on the partition under the action of buoyancy, realize automatic blocking of the through hole, ensure the reliability and stability of the blocking action, and ensure that the middle urine is accurately collected.

[0033] Furthermore, the vacuum tube is connected to a liquid inlet pipe, a sealing gasket is fixedly connected to the inside of the liquid inlet pipe near the side of the accommodating tube, a cross is provided on the sealing gasket, a sealing cover is detachably connected to the free end of the liquid inlet pipe, and a connecting pipe is connected to the side of the upper chamber near the partition, and the connecting pipe can be inserted into the liquid inlet pipe through the sealing gasket.

[0034] The beneficial effects of this solution are as follows: The gasket is fixed on one side of the liquid inlet pipe close to the receiving cylinder, and there is a cross-shaped opening on it. When the connecting pipe is inserted into the liquid inlet pipe, the cross-shaped opening will tightly wrap the connecting pipe, playing a good sealing role and effectively preventing urine leakage; when the sealing cover at the free end of the liquid inlet pipe is not connected to the receiving cylinder, it can prevent external impurities from entering the vacuum tube, ensuring that the collected urine sample is not contaminated and maintaining the accuracy of the test results. The connecting pipe of the upper chamber can be easily inserted into the liquid inlet pipe through the gasket. This connection method is simple and convenient, facilitating the operator to quickly connect the vacuum tube to the receiving cylinder and complete the preparation work for urine collection. After the collection is completed, the connecting pipe can also be easily pulled out to achieve the disassembly and separation of the vacuum tube and the receiving cylinder, facilitating subsequent processing. In addition, the cross-shaped opening on the gasket is ingeniously designed. When the connecting pipe is inserted, it remains sealed, and when not inserted, it closes to prevent urine backflow or gas entry; the sealing cover is detachable, which not only meets the sealing requirements of the vacuum tube before urine collection but also can be easily opened when the receiving cylinder needs to be connected, adapting to various operation requirements during the urine collection process.

[0035] Further, the vacuum tube is located below the collection plate, and the collection plate can shield the vacuum tube.

[0036] The beneficial effects of this solution are as follows: Since the collection plate can shield the vacuum tube in this technical solution, it can prevent urine from splashing onto the vacuum tube, ensuring the hygiene and safety of the entire sampling and testing process.

[0037] Further, the first cover body is a rubber cover.

[0038] The beneficial effects of this solution are as follows: Since the first cover body is a rubber cover in this technical solution, the sealing performance of the first cover body for the liquid inlet hole is improved.

[0039] Further, a handle is installed on the collection plate.

[0040] The beneficial effects of this solution are as follows: Due to the setting of the handle in this technical solution, it is not only convenient for sampling but also can prevent urine from splashing onto the patient's hand. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] As Figure 1 shown, a horn-shaped diversion pipe 7 is integrally formed at the top of the receiving cylinder 1, and the small-diameter end of the diversion pipe 7 communicates with the upper chamber. A collecting plate 8 is adhesively bonded to the top of the large-diameter end of the diversion pipe 7, a collecting groove 9 is provided at the top of the collecting plate 8, a connecting hole 10 is provided at the bottom of the collecting groove 9, and the size of the connecting hole 10 is smaller than the size of the large-diameter end of the diversion pipe 7. When urine is discharged into the diversion pipe 7, the collecting plate 8 can play a role in preventing splashing. A handle 11 is adhesively bonded to the right side surface of the collecting plate 8.

[0052] As Figure 1 and Figure 3As shown, the collection unit includes a vacuum tube 12. The left side of the vacuum tube 12 is connected to an upwardly inclined liquid inlet tube 13. A gasket 14 is adhesively bonded inside the liquid inlet tube 13 near the left end. A cross-shaped opening 15 is formed on the gasket 14. A sealing cover 16 is snap-fitted to the left end of the liquid inlet tube 13. The right end of the receiving cylinder 1 is connected to a downwardly inclined connecting tube 17. The connecting tube 17 is connected to the upper chamber and is disposed on one side close to the partition 2. The connecting tube 17 can be inserted into the liquid inlet tube 13 through the gasket 14. The vacuum tube 12 is located below the collection plate 8. Since the vacuum tube 12 is located below the collection plate 8, the collection plate 8 can shield the vacuum tube 12 to prevent urine from splashing onto the vacuum tube 12, ensuring the cleanliness of the vacuum tube 12.

[0053] As Figure 3 and Figure 4 shown, a first cover body 18 is adhesively bonded to the top of the vacuum tube 12. A detection unit is slidably disposed on the first cover body 18.

The urine flows through the diversion tube 7 into the upper chamber of the receiving cylinder 1 and then into the lower chamber through the through hole 3. As the urine volume in the lower chamber increases, the blocking ball 6 is gradually lifted. When the urine volume in the lower chamber reaches the set initial urine volume, the blocking ball 6 blocks the through hole 3. At this time, the subsequent middle-section urine is intercepted in the upper chamber and flows into the vacuum tube 12 through the connecting tube 17 to complete the collection, and the remaining middle-section urine and the subsequent urine are retained in the upper chamber. After urine collection, first pour out the urine in the receiving cylinder 1, then remove the vacuum tube 12 from the receiving cylinder 1, discard the receiving cylinder 1, and seal the liquid inlet tube 13 with the sealing cover 16.

[0056] When urine detection is required, the test strip is pre-clamped on the second cover body 21. During detection, press the collection tube 19 downward so that the liquid inlet hole 20 is immersed in the urine in the vacuum tube 12. The urine enters the collection tube 19 through the liquid inlet hole 20 and soaks the test strip. After the sampling is completed, take out the test strip, blot the excess urine with absorbent paper, and finally put it into a urine analyzer for inspection and analysis.
