Description
Technical Field
[0001] The utility model belongs to the technical field of urine sampling for urine test, and particularly relates to a double-cup urine sampling device for diabetes detection. Background Art
[0002] As a common chronic metabolic disease, the incidence of diabetes has been increasing year by year. Diabetic nephropathy is a serious complication of it, which is particularly threatening to type 1 diabetic patients. Early diagnosis is of great significance for improving the prognosis. Detection of urinary microalbumin is the key to early detection of diabetic nephropathy. Its detection methods and requirements are different from those of ordinary urine routine. A separate sample needs to be collected for this detection, and another for routine item detection.
[0003] In the hospital laboratory, different detection areas or instruments are usually set up to carry out these detections separately. For example, immunoturbidimetry and other specialized methods are often used for the detection of urinary microalbumin, which is carried out in a specific immunoassay area; while urine routine is detected in the conventional urine analysis area with the help of an automated urine analyzer.
[0004] The traditional detection method adopts the process of transferring urine to another detection location for continued detection after one detection is completed. This process greatly prolongs the detection time, resulting in a slower presentation of the patient's test report, which not only wastes the patient's time but also may delay the diagnosis and treatment of the disease. At the same time, most traditional urine sampling devices are single-cup sampling types (such as two urine sampling devices with publication numbers CN222426076U and CN222383247U). During the patient's urination process, it is difficult to obtain two cups of samples simultaneously, which cannot meet the sample requirements for separate detections of urinary microalbumin and other routine items. It brings inconvenience to the patient and is not conducive to the efficient development of the detection work.
[0005] In view of the many drawbacks of the above traditional detection methods and sampling devices, it is of great practical significance and clinical application value to develop a double-cup urine sampling device for diabetes detection that can obtain two urine samples simultaneously, is convenient and fast, and helps to improve the detection efficiency.

The rubber sealing plugs are inserted and installed in the connecting sleeves B, and the puncture device B penetrates through the rubber sealing plug and is located inside the sampling tube.
[0011] In the above technical solution, a connecting sleeve A is fixedly installed on the outer surface of the puncture device A. The puncture device A and the puncture device B are of the same size. The connecting sleeve A and the connecting sleeve B are of the same size.

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0030] The front, back, left, right, top and bottom in this embodiment are described with Figure 1 as the reference plane. Please refer to Figures 1 - 4 , the present invention provides a technical solution:
[0031] A double-cup urine sampling device for diabetes detection includes a cup body 1 with a handle. The handle part of the cup body 1 is provided with a folding section at one end close to the cup body 1. The whole handle part is made of plastic material. When the cup body 1 is packaged, the handle part can be folded and stored towards the side wall of the cup body 1 to reduce the overall packaging volume of the device.
[0032] As Figure 3 shown, a shunt sleeve 2 is fixedly installed in the cup body 1 through medical-grade sealant. Both the shunt sleeve 2 and the cup body 1 are made of transparent PVC plastic material. After the shunt sleeve 2 is installed, the inner cavity of the cup body 1 is divided into a perfusion cavity 11 and an overflow cavity 12. An overflow port 21 is opened for communication between the perfusion cavity 11 and the overflow cavity 12. The overflow port 21 is pre-opened during the production of the shunt sleeve 2, and a first drain port 13 is penetrated in the overflow cavity 12. The first drain port 13 is pre-opened during the production of the cup body 1. A puncture device A 111 is fixedly installed on the lower surface of the cup body 1. The puncture device A 111 is communicated with the perfusion cavity 11 by penetrating the bottom of the cup body 1. A three-way shunt device 3 is detachably installed on the lower surface of the cup body 1. The puncture device A 111 is inserted and installed at the liquid inlet end of the three-way shunt device 3, and sampling tubes 4 are detachably installed at the liquid discharge ends of the three-way shunt device 3.
[0033] When in use, fold and open the handle part of the cup body 1. After making it perpendicular to the outer surface of the cup body 1, hold the handle part by hand. After pressing the index finger tightly against the outer surface of the cup body 1, the cup body 1 can be stably held. Subsequently, turn the first row of ports 13 away from the patient and align them with the urinal. Then, align the urination organ with the perfusion cavity 11 to discharge urine. The urine first enters the perfusion cavity 11, passes through the puncture device A111, and enters the three-way shunt device 3. After being shunted by the three-way shunt device 3, it enters the two sampling tubes 4 for the sampling work of double-cup urine. During the continuous urine discharge process of the patient, the urine higher than the overflow port 21 will enter the overflow cavity 12 and finally be discharged into the urinal from the first row of ports 13. After the patient finishes discharging urine, pour out the urine in the cup body 1, and then separate the two sampling tubes 4 from the three-way shunt device 3. Compared with the prior art, the overall structure of this device is simply designed, and it can obtain two urine samples simultaneously, is convenient and fast to use, helps to synchronize the detection of urinary microalbumin and routine items, and improves the detection efficiency.
[0034] It should be noted that, as Figure 2 shown, two card slots 15 are provided on both the left and right surfaces of the cup body 1 (due to the perspective problem, only the two card slots 15 on the right side of the cup body 1 are shown in the figure). Combining Figure 4 、 Figure 5 and Figure 6 shown, Figure 6 further shows the local structure at a in Figure 5 . The local structure at a includes a three-way shunt pipe 32. The liquid inlet end of the three-way shunt pipe 32 is in plug-in fit with the puncture device A111. When the U-shaped frame 31 is fixedly connected to the cup body 1, the puncture device A111 is inserted into the liquid inlet port of the three-way shunt pipe 32. A connecting sleeve A112 is fixedly installed on the outer surface of the puncture device A111, and a sealing gasket 321 is fixedly installed on the outer surface of the liquid inlet end of the three-way shunt pipe 32. When the U-shaped frame 31 is fixed, the upper surface of the sealing gasket 321 fits with the inner surface of the connecting sleeve A112, which can ensure the sealing performance after the puncture device A111 and the three-way shunt pipe 32 are inserted and installed. The three-way shunt pipe 32 is clamped in the U-shaped frame 31. Four J-shaped elastic clamping blocks 311 are integrally formed on the upper surface of the U-shaped frame 31. When the U-shaped frame 31 is connected to the cup body 1, the J-shaped elastic clamping blocks 311 can be clamped in the corresponding card slots 15.
[0035] As Figure 6As shown, two puncture devices B33 are fixedly installed on the lower surface of the U-shaped frame 31. The two puncture devices B33 are respectively communicated with the liquid discharge end of the three-way shunt tube 32. Connecting sleeves B34 are fixedly installed on the outer surfaces of the puncture devices B33. Rubber sealing plugs 41 are fixedly installed in the sample inlet of the sampling tube 4. The rubber sealing plugs 41 are inserted and installed in the connecting sleeves B34. Through the elasticity of the rubber sealing plugs 41 themselves, they are inserted into the connecting sleeves B34 to maintain a certain fixing effect, and the puncture devices B33 penetrate through the rubber sealing plugs 41 and are located in the sampling tube 4. During urine sampling, the urine in the perfusion cavity 11 first enters the three-way shunt tube 32 through the puncture device A111 for shunting. The shunted urine respectively enters the two sampling tubes 4 through the two puncture devices B33 on both sides for sampling.
[0036] To meet the different requirements of single-tube urine sampling for some patients and double-tube urine sampling for some patients in actual use, and to make this urine sampling device compatible with single-tube urine sampling operations, the puncture device A111 and the puncture device B33 are set to the same specification size, and at the same time, the specification sizes of the connecting sleeve A112 and the connecting sleeve B34 are kept consistent. According to Figure 7 , Figure 8 and Figure 9 shown, Figure 9 For Figure 8 the schematic diagram of the partial structure at b in, in the application scenario of single-tube urine sampling, the sampling tube 4 can be directly inserted into the connecting sleeve A112, and the puncture device A111 is used to inject liquid into the single sampling tube 4 to meet the actual use requirements of single-tube urine sampling for patients.
[0037] During the actual production and packaging process of this urine sampling device, it can be judged according to whether the three-way shunt tube 32 is equipped in the product packaging bag which specific use scenario the device is applicable to. If there is no three-way shunt tube 32 in the packaging bag, the device is applicable to the single-tube urine sampling scenario; if the three-way shunt tube 32 is installed in the packaging bag, the device is applicable to the double-tube urine sampling scenario.
[0038] Finally, in view of the differences in the urine output of patients, to prevent the excessive urine from overflowing from the top of the cup body 1 due to the inability of a single first discharge port 13 to discharge the excessive urine in time, as Figure 3 shown, a second discharge port 14 is specifically added in the overflow cavity 12. The second discharge port 14 is arranged above the first discharge port 13 to form a hierarchical discharge structure. When the discharge capacity of the first discharge port 13 is saturated, the excess urine can be quickly discharged through the second discharge port 14, effectively avoiding the risk of urine overflow and ensuring the high efficiency and stability of the device's discharge system.
