Abstract
Description
Technical Field
[0001] This invention relates to the field of urine collection technology, and in particular to a urine collection and storage device for nephrology. Background Technology
[0002] Medical supplies are a general term for items used to treat wounds or diseases; they are items used in the medical process on humans.
[0003] Kidney disease is a common and frequently occurring disease. If it worsens, it can develop into uremia, which seriously endangers people's health. The routine examination method in nephrology is to test urine. In this test, patients need to collect urine themselves using a urine bottle. However, most of the existing urine bottles and collection devices are designed separately, which can easily lead to urine spillage during use. At the same time, urine collection may produce an irritating odor.
[0004] As disclosed in CN211749738U, a urine collection and storage device for nephrology solves the problems of existing urine bottles and collectors being mostly designed separately, which easily leads to urine spillage during use and the generation of irritating odors during urine collection. This urine collection and storage device for nephrology has the advantages of integrated collection and storage and effective prevention of odor emission, making it convenient for patients to collect urine and avoiding the impact of irritating odors generated by urine evaporation after collection on the medical testing environment.
[0005] However, the urine collection device is only a single container and cannot collect the first, middle and last segments of urine separately. Patients need to change containers frequently during collection, which is cumbersome and can easily lead to mixing of different segments of urine, affecting the accuracy of the test results.
[0006] Therefore, we urgently need to provide a urine collection and storage device for nephrology. Summary of the Invention
[0007] The main objective of this invention is to provide a urine collection and storage device for nephrology, which can effectively solve the problems mentioned above.
[0008] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A urine collection and storage device for nephrology includes a housing, an annular baffle mounted on the top of the housing, a handle fixedly mounted on the outside of the housing, three urine collection tubes mounted on the bottom of the housing for separate urine collection, and a segmentation mechanism inside the housing for separate collection of the first, middle, and last segments of urine.
[0009] The segmented mechanism includes an installation plate rotatably connected inside a housing. An installation cavity is provided inside the housing. A gear is fixedly installed on the outer side of the installation plate, and the gear extends into the installation cavity. A servo motor is fixedly installed on the inner wall of the installation cavity. A rotating shaft is fixedly installed at the output end of the servo motor. A gear two that meshes with gear one is fixedly installed on the outer side of the lower end of the rotating shaft to drive the installation plate to rotate. A urine guide plate is fixedly installed at the lower end of the annular baffle to guide the urine.
[0010] The servo motor drives the shaft to rotate, and the meshing of gear one and gear two causes the mounting plate to rotate the three urine collection tubes, so that the three urine collection tubes are positioned sequentially at the lower end of the catheter plate.
[0011] Preferably, the annular baffle is detachably connected to the housing via threads, which is used for disassembling the housing and the annular baffle to facilitate subsequent disinfection and cleaning. A sealing ring is installed at the connection between the mounting plate and the housing to prevent urine from entering the mounting cavity opened in the housing.
[0012] Preferably, the upper ends of the three urine storage tubes are provided with external threads, and the surface of the mounting plate is provided with three threaded holes distributed at equal angles. The three urine storage tubes are connected to the mounting plate by threads for installation of the urine storage tubes. A label is installed on the outside of the urine storage tubes to mark patient information and avoid confusion.
[0013] Preferably, a lifting mechanism is provided at the connection between the urine storage tube and the catheter plate. The lifting mechanism includes a sealing ball, which is movably installed inside the catheter plate for sealing the catheter plate. An installation frame is fixedly installed at the upper end of the three urine storage tubes. A cylinder is fixedly installed on the top of the installation frame. A spring is fixedly installed inside the cylinder. A limiting plate is fixedly installed on the top of the spring. A push rod is fixedly installed on the top of the limiting plate and extends above the cylinder for pushing the sealing ball open.
[0014] Preferably, the urine outlet at the lower end of the catheter plate abuts against the upper surface of the mounting plate. After the sealing ball seals the lower end of the catheter plate, the catheter plate is double-sealed in conjunction with the adhesion between the catheter plate and the surface of the mounting plate to prevent urine leakage from the catheter plate.
[0015] Preferably, a sealing membrane is installed at the lower end of the inside of the urine storage tube, and a pressure sensor is installed at the bottom of the sealing membrane at the lower end of the inside of the urine storage tube for detecting the weight of urine in the urine storage tube.
[0016] Preferably, a controller can be installed on the outside of the housing, and the controller is electrically connected to the servo motor. The pressure sensor is electrically connected to the controller. When the pressure sensor reaches the set value, the controller controls the action of the servo motor to move the next urine collection tube under the catheter plate.
[0017] Preferably, a filtration mechanism is provided at the lower end of the annular baffle. The filtration mechanism includes a filter screen one, which is fixedly installed at the lower end of the annular baffle. A filter screen two is fixedly installed at the lower end of the filter screen one to filter flocculent matter and sediment contained in the urine. The top of the filter screen two is fixedly equipped with evenly distributed protrusions to puncture the foam in the urine.
[0018] Compared with the prior art, the present invention has the following beneficial effects: 1. This device, through its segmented design and the cooperation of a servo motor, gear transmission, and mounting plate, can drive three urine collection tubes to sequentially correspond to the urine outlet of the catheter plate, automatically collecting the first, middle, and last segments of urine separately. This eliminates the need for patients to frequently change containers, avoids mixing of different segments of urine, and ensures the accuracy of urine test results from the source.
[0019] 2. This device effectively filters out impurities such as flocculent matter and sediment in urine through its designed filtration mechanism, preventing impurities from entering the urine storage tube and interfering with subsequent urine testing, thereby improving the accuracy and reliability of the test results. In addition, the protrusions on the second filter screen puncture the foam in the urine, eliminating the influence of foam on the judgment of urine collection volume. Attached Figure Description

Detailed Implementation
[0022] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.
[0023] Example 1, as Figures 1-4 As shown, a urine collection and storage device for nephrology includes a housing 1, an annular baffle 2 installed on the top of the housing 1, a handle 3 fixedly installed on the outside of the housing 1, and three urine collection tubes 4 installed at the bottom of the housing 1 for separate urine collection. The housing 1 is provided with a segmentation mechanism for separate collection of the first, middle and last segments of urine.
[0024] The segmented mechanism includes an installation plate 51, which is rotatably connected to the inside of the housing 1. An installation cavity is provided inside the housing 1. A gear 52 is fixedly installed on the outside of the installation plate 51 and extends into the installation cavity. A servo motor 53 is fixedly installed on the inner wall of the installation cavity. The servo motor 53 is controlled by a preset program of the controller. The single drive rotation angle is 120° to adapt to three urine storage tubes 4 distributed at equal angles. The speed is set to 5-10 r / min to avoid urine splashing due to excessive rotation. A rotating shaft 54 is fixedly installed at the output end of the servo motor 53. A gear 55 that meshes with the gear 52 is fixedly installed on the outer side of the lower end of the rotating shaft 54 to drive the installation plate 51 to rotate. A urine guide plate 56 is fixedly installed at the lower end of the annular baffle 2 to guide the urine.
[0025] The servo motor 53 drives the rotating shaft 54 to rotate, and the meshing of gear 1 52 and gear 2 55 causes the mounting plate 51 to drive the three urine storage tubes 4 to rotate, so that the three urine storage tubes 4 are positioned sequentially at the lower end of the urine guide plate 56.
[0026] The annular baffle 2 is detachably connected to the housing 1 by threads, which is used to disassemble the housing 1 and the annular baffle 2 for subsequent disinfection and cleaning. A sealing ring is installed at the connection between the mounting plate 51 and the housing 1 to prevent urine from entering the mounting cavity opened in the housing 1.
[0027] The upper ends of the three urine storage tubes 4 are provided with external threads, and the surface of the mounting plate 51 is provided with three threaded holes distributed at equal angles. The three urine storage tubes 4 are connected to the mounting plate 51 by threads for installation of the urine storage tubes 4. Labels 10 are installed on the outside of the urine storage tubes 4 for marking patient information to avoid confusion.
[0028] like Figures 4-6As shown, a lifting mechanism is provided at the connection between the urine storage tube 4 and the catheter plate 56. The lifting mechanism includes a blocking ball 61, which is movably installed inside the catheter plate 56 to block the catheter plate 56. The blocking ball 61 has a diameter of 8mm, and the inner diameter of the urine outlet of the catheter plate 56 is 6mm. The blocking ball 61 can completely block the urine outlet. The top of the push rod 66 has a spherical structure with a diameter of 3mm and a lifting height of 5mm to ensure that the blocking ball 61 is completely pushed open without jamming. An installation frame 62 is fixedly installed at the upper end of the three urine storage tubes 4. A cylinder 63 is fixedly installed on the top of the installation frame 62. A spring 64 is fixedly installed inside the cylinder 63. A limit plate 65 is fixedly installed on the top of the spring 64. A push rod 66 is fixedly installed on the top of the limit plate 65 and extends above the cylinder 63 to push the blocking ball 61 open.
[0029] The urine outlet at the lower end of the catheter plate 56 abuts against the upper surface of the mounting plate 51. After the sealing ball 61 seals the lower end of the catheter plate 56, the catheter plate 56 is double-sealed in conjunction with the adhesion between the catheter plate 56 and the surface of the mounting plate 51 to prevent urine leakage from the catheter plate 56.
[0030] A sealing membrane 7 is installed at the lower end of the inside of the urine storage tube 4. A pressure sensor 8 is installed at the bottom of the sealing membrane 7 at the lower end of the inside of the urine storage tube 4 to detect the weight of the urine inside the urine storage tube 4.
[0031] A controller can be installed on the outside of the housing 1, and the controller is electrically connected to the servo motor 53. The pressure sensor 8 is electrically connected to the controller. When the pressure sensor 8 reaches the set value, the controller controls the action of the servo motor 53 to move the next urine storage tube 4 to below the catheter plate 56.
[0032] Example 2, as Figures 2-4 As shown, a filtration mechanism is provided at the lower end of the annular baffle 2. The filtration mechanism includes a filter screen 91, which is fixedly installed at the lower end of the annular baffle 2. A filter screen 92 is fixedly installed at the lower end of the filter screen 91 to filter flocculent matter and sediment contained in the urine. The top of the filter screen 92 is fixedly equipped with evenly distributed protrusions 93 to puncture the foam in the urine.
[0033] Working principle: Three urine collection tubes 4 are screwed into the three equally angled threaded holes on the surface of the mounting plate 51 through their external threads at the upper end, thus completing the fixed installation of the urine collection tubes 4. At the same time, the patient information is marked on the label 10 on the outside of the urine collection tubes 4 to avoid confusion during subsequent testing. At this time, as the urine collection tube 4, which is directly opposite the urine outlet of the catheter plate 56, is screwed in and moved upward, the spring 64 in the top cylinder 63 of the internal mounting bracket 62 will push the limiting plate 65 upward, thereby driving the push rod 66 to extend out of the cylinder 63, pushing the sealing ball 61 inside the catheter plate 56 upward, so that the catheter plate 56 and the urine collection tube 4 are connected, preparing for urine collection.
[0034] When a patient undergoes urine collection, the urine first enters the annular baffle 2. As it flows through the filtration mechanism, it undergoes preliminary filtration through filter screen 91 to intercept larger particles such as flocculent matter and sediment. Subsequently, it undergoes secondary fine filtration through filter screen 92 to further remove smaller impurities. At the same time, the evenly distributed protrusions 93 on the top of filter screen 92 will puncture any foam generated in the urine, preventing foam from affecting the judgment of the actual amount of urine collected. After filtration, the urine flows smoothly into the currently connected urine storage tube 4 under the guidance of the catheter plate 56, and the collection of the initial urine begins.
[0035] As the amount of urine in the storage tube 4 increases, the weight of the urine acts on the sealing membrane 7 at the lower end of the storage tube 4, and is then transmitted to the pressure sensor 8 at the bottom of the sealing membrane 7. When the weight of the urine reaches the preset threshold of the pressure sensor 8, the pressure sensor 8 will send a signal to the controller installed on the outside of the housing 1. After receiving the signal, the controller immediately controls the servo motor 53 in the mounting cavity to start. The output end of the servo motor 53 drives the rotating shaft 54 to rotate. Through the meshing transmission between the gear 2 55 and the gear 1 52 on the outside of the mounting plate 51, the mounting plate 51 is driven to rotate, which in turn drives the three storage tubes 4 to rotate synchronously.
[0036] As the installation plate 51 rotates, the urine storage tube 4, which was originally connected to the urine outlet of the urine catheter 56, gradually deviates from the urine outlet of the urine catheter 56. The push rod 66 no longer applies a pushing force to the sealing ball 61. The sealing ball 61 moves downward under its own weight, sealing the urine outlet of the urine catheter 56. At the same time, the lower end of the urine catheter 56 and the upper surface of the installation plate 51 always remain in contact and fit together, forming a double sealing structure, which effectively prevents the leakage of residual urine in the urine catheter 56 and avoids the mixing of urine from different sections.
[0037] When the mounting plate 51 rotates to align the next urine collection tube 4 with the outlet of the urine guide plate 56, the push rod 66 inside the urine collection tube 4 is once again pushed upward by the spring 64, lifting the sealing ball 61 and connecting the urine guide plate 56 with the urine collection tube 4. The filtered urine continues to flow in, and the collection of midstream urine begins. By repeating the above process of pressure detection, servo motor 53 drive, urine collection tube 4 switching, and sealing, the collection of midstream urine can be completed.
[0038] After all three urine samples have been collected, the three urine collection tubes 4 are screwed out from the threaded holes of the mounting plate 51. After sealing the urine collection tubes 4 with sealing caps, the urine collection tubes 4 containing different urine samples can be sent for testing. Since the three urine samples are isolated from each other and do not come into contact during the collection process, the accuracy of the urine test results is effectively guaranteed. At the same time, the entire collection process does not require frequent manual container replacement, making the operation convenient.
[0039] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
