Description

Technical Field

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

[0002] Urinalysis is one of the three routine clinical tests. As an examination of excretory substances, urine reflects the body's metabolic status and is an important indicator for the diagnosis of many diseases. Many kidney diseases can present with proteinuria or formed elements in the urine sediment in the early stages. Abnormal urinalysis results are often a sign of kidney or urinary tract diseases. Therefore, when patients seek medical treatment, it is often necessary to collect urine samples using a urine sampling device to provide urinalysis samples for medical staff.

[0003] A Chinese patent application with publication number CN119235367A discloses a urine sampling device belonging to the field of medical testing equipment. It includes a sampling driver and a disposable sampling component mounted on the sampling driver. The sampling driver includes a chassis and an adjustable constant-speed moving mechanism. The disposable sampling component includes a disposable urine reservoir and a urine collector. The adjustable constant-speed moving mechanism is equipped with a tube head fixing frame. The side wall of the chassis has a transverse sliding hole. The tube head fixing frame slides through the transverse sliding hole and is located outside the chassis. The side wall of the chassis has a mounting frame. The disposable urine reservoir is secured within the mounting frame. The tube head fixing frame slides above the disposable urine reservoir. The bottom end of the urine collector is connected to a corrugated pipe. The end of the corrugated pipe away from the urine collector has a drain pipe head, which is mounted on the tube head fixing frame. This invention provides a urine sampling device that can accurately collect midstream urine based on the patient's urine volume while ensuring a sufficient sample volume.

[0004] A Chinese patent application with publication number CN221013321U discloses a urine sampling device, including a main body, a connecting pipe, a funnel, and an anti-overflow component. The anti-overflow component includes an extension tube, a base plate, an extension member, and an auxiliary member. The extension tube is slidably connected to the main body, and the base plate is fixedly connected to the extension tube. The extension member is respectively disposed on the main body and the base plate, and the auxiliary member is disposed on the connecting pipe. As the patient urinates through the funnel into the main body, the urine falls onto the base plate. As the amount of urine increases, the weight on the base plate increases. When the weight of the urine on the base plate reaches a certain value, the base plate, through the extension member, drives the extension tube to move downward on the main body, thereby continuously increasing the volume between the main body and the extension tube, thus collecting the urine and preventing urine from overflowing from the funnel opening due to excessive urine output. This prevents urine from spilling and thus avoids soiling the patient's hands, making it convenient to use.

[0005] A Chinese patent application with publication number CN219835631U discloses a urine sampling device, including a urinal. One end of the urinal has a spout, and the top of the urinal has a handle. The bottom of the urinal has a telescopic cavity, within which a support plate is slidably mounted. The top of the support plate has a Velcro layer. A guide tube is installed through one side of the urinal, connecting to a quantitative sampling component. This invention addresses the problem that traditional nephrology urine sampling devices are only used by mobile patients for self-sampling. Some patients with limited mobility rely on bedpans or urinals for sampling, which can easily contaminate patients, doctors, and nurses, has poor protective performance, and is inconvenient.

[0006] However, this urine sampling device has the following drawbacks in practical use: Existing urine sampling devices often use a single urine sampler to collect urine. The simultaneous applicability of multiple urine samplers distributed in different locations is not high. Furthermore, the use of multiple urine samplers requires frequent disassembly and replacement when using a single urine sampler for different patients. In addition, the urine sampler does not provide good splash protection when collecting urine, which reduces the cleanliness of the urine sampler surface.

[0007] 2. While existing urine samplers can effectively classify and store urine from different time periods, they are not efficient at simultaneously transferring urine from different time periods to test tubes. This increases the tediousness of staff pouring urine from different time periods into test tubes and also poses a risk of leakage, thus increasing medical and health risks. Summary of the Invention

[0008] The purpose of this invention is to provide a urine sampling device to solve the problems mentioned in the background art.

[0009] To achieve the above-mentioned objectives, the present invention adopts the following technical solution: The present invention provides a urine sampling device, comprising a device body, a sampler body, a splash shield switching mechanism, and an adjustment mechanism. A rotating shaft is rotatably connected to the top of the device body, a conversion block is fixedly connected to the top of the rotating shaft, and a switching mechanism is provided at the bottom of the rotating shaft. A mounting plate is fixedly connected to the outer wall of the conversion block, and a connecting rod is detachably connected to the inner wall of the mounting plate. One end of the connecting rod is fixedly connected to the sampler body, and an infusion tube is detachably connected to the bottom of the sampler body. A collector is fixedly connected to one end of the infusion tube, and an adjustment mechanism is provided at the top of the collector. The switching mechanism includes a sector gear and a connecting gear. A first motor is provided on the top of the main body of the device. The output end of the first motor is fixedly connected to the sector gear. The outer wall of the sector gear is meshed with a connecting gear that is rotatably connected to the top of the main body of the device. The adjustment mechanism includes a first worm gear, a second worm gear, a sampling tube, and a sector plate. A connecting plate is fixedly connected to the top of the collector. The first worm gear is rotatably connected to the outer wall of the connecting plate. A connecting shaft is fixedly connected to the rotation center of the first worm gear. A placement plate is fixedly connected to the outer wall of the connecting shaft. A sampling tube is inserted into the inner wall of the placement plate. A second worm gear is rotatably connected to the outer wall of the connecting plate. The rotation center of the second worm gear is fixedly connected to a fan-shaped plate located inside the collector via a rotating shaft. When the sampler assists the patient in urine collection, the cross-shaped mounting plate and the sampler bodies distributed around the mounting plate allow for simultaneous urine collection from multiple patients, as well as enabling the switching of samplers when collecting urine from different patients. It also allows for centralized replacement of urine collectors, preventing frequent replacement of individual samplers and reducing the complexity of collecting urine from different patients. The synchronous intermittent rotation of the placement plate and the fan-shaped plate allows for the separation and storage of patient urine in a fan shape, improving the efficiency of urine collection at different times at the bottom of the collector. The system facilitates the convenient input of urine into test tubes, preventing spillage caused by staff pouring urine into the tubes. When the drive plate rotates, the connecting shaft causes the placement plate to rotate synchronously, moving the test tubes below the discharge tube. This ensures that the storage spaces at the partitions of the drive plate correspond one-to-one with the test tubes in different positions, achieving the effect of synchronously collecting urine from different time periods. Through the intermittent rotation of the drive plate, urine can be stored in the collector during collection. As the drive plate rotates within the collector, urine from different time periods can be separated and stored within the collector, preventing mixing of urine from different periods and affecting the accuracy of the urine test data.

[0010] As a preferred embodiment of the present invention, a connecting shaft is fixedly connected to the top of the conversion block, a connecting rod is fixedly connected to the top of the connecting shaft, a first electric push rod is fixedly connected to the outer wall of the connecting rod, and a splash shield is fixedly connected to the output end of the first electric push rod. By the lifting and lowering movement of the splash shield, when collecting and sampling the patient's urine through the sampler body, the splash shield can be driven to descend to shield the outer wall of the sampler body. The splash shield is set in an inclined position to prevent splashing of urine and improve the surface cleanliness of the sampler.

[0011] As a preferred embodiment of the present invention, the splash shield is distributed in an inclined manner, and the outer wall contour of the splash shield is U-shaped, the outer wall contour of the connecting rod is cross-shaped, and the splash shield is disposed around the connecting rod.

[0012] As a preferred embodiment of the present invention, the outer wall contour of the mounting plate is cross-shaped, and four sets of sampler bodies are provided, with the positions of the four sets of sampler bodies distributed around the perimeter of the mounting plate. The sampler body and the splash guard are configured in a one-to-one correspondence.

[0013] As a preferred embodiment of the present invention, a slot is provided at the connection between the inner wall of the mounting plate and the connecting rod, and a nut is provided on the outer wall of the mounting plate. A bolt that is slidably connected to the outer wall of the connecting rod is threaded onto the inner wall of the nut. An installation slot is provided at the connection between the outer wall of the connecting rod and the bolt. By using the bolt and the installation slot together, after multiple samplers have been used, the connecting rod can be disassembled from the mounting plate one by one by disengaging the bolt from the installation slot. This allows for the disassembly and replacement of the samplers around the mounting plate one by one, improving the efficiency of medical staff in simultaneously disassembling and replacing multiple samplers at a time.

[0014] As a preferred embodiment of the present invention, the bottom of the collector is fixedly connected to a feed pipe disposed on the rotation path of the sampling tube, the outer wall of the connecting plate is provided with a second motor, the output end of the second motor is fixedly connected to a worm that meshes with the outer wall of the first worm wheel, and the worm and the second worm wheel are mutually meshed.

[0015] As a preferred embodiment of the present invention, the bottom of the placement plate is fixedly connected to a support plate that fits against the bottom of the sampling test tube. The outer wall contour of the placement plate is cross-shaped, and the outer wall contour of the fan-shaped plate is grid-shaped. The outer wall of the fan-shaped plate forms liquid storage cavities at different positions. By synchronously and intermittently rotating the placement plate and the fan-shaped plate, when the patient's urine is separated and stored in a fan shape, in order to improve the convenience of automatically inputting urine into the test tube at the bottom of the collector at different times and to prevent leakage caused by staff pouring urine into the test tube, when the fan-shaped plate is driven to rotate, the placement plate is driven to rotate synchronously through the connection of the connecting shaft, and the test tube is moved to the bottom of the discharge tube, so that the storage space at the separation of the fan-shaped plate corresponds one-to-one with the test tube at different positions, achieving the effect of synchronously converting and collecting urine at different times.

[0016] As a preferred embodiment of the present invention, the bottom of the collector is provided with an inlet that communicates with the inner wall of the discharge pipe.

[0017] As a preferred embodiment of the present invention, a second electric push rod is fixedly connected to the bottom of the collector, and a lifting block located below the placement plate is fixedly connected to the output end of the second electric push rod.

[0018] As a preferred embodiment of the present invention, the inner wall contour of the sampling tube is larger than the outer wall contour of the feeding tube, and the feeding tube is arranged on the lifting path of the sampling tube.

[0019] Compared with existing technologies, one or more of the above technical solutions have the following beneficial effects: 1. This urine sampling device, when assisting patients in urine collection with the sampler, can achieve the effect of simultaneous urine collection for multiple patients through the cross-shaped mounting plate and the distribution of sampler bodies around the mounting plate. It can also achieve the effect of switching between samplers when collecting urine from different patients, and centrally replace urine collectors to prevent frequent replacement of individual samplers and increase the cumbersome process of collecting urine from different patients. Furthermore, this technical solution, through the intermittent rotation of the sector plate, enables the collection and storage of urine during patient urine collection. As the sector plate rotates within the collector, urine from different time periods is separated and stored within the collector, preventing mixing of urine from different time periods and thus ensuring the accuracy of the patient's urine test data.

[0020] Furthermore, this technical solution, through the synchronous intermittent rotation of the placement plate and the fan-shaped plate, enables the separation and storage of patient urine in a fan shape. To improve the convenience of automatically inputting urine into test tubes at the bottom of the collector at different times and to prevent leakage caused by staff pouring urine into the test tubes, when the fan-shaped plate is driven to rotate, the placement plate is driven to rotate synchronously through the connecting shaft, and the test tubes are moved to the bottom of the discharge tube. This ensures that the storage space at the fan-shaped plate's separation point corresponds one-to-one with the test tubes at different positions, achieving the effect of synchronously converting and collecting urine at different times.

[0021] 2. This urine sampling device, through the use of bolts and mounting slots, allows for the disassembly of connecting rods from the mounting plate after multiple samplers have been used. This enables the individual removal and replacement of the samplers around the mounting plate, improving the efficiency of medical staff in simultaneously removing and replacing multiple samplers at a time.

[0022] 3. This urine sampling device, through the lifting and lowering movement of the anti-splash cover, can shield the outer wall of the sampler body by driving the anti-splash cover to descend when collecting urine from the patient through the sampler body. The anti-splash cover is set at an angle to prevent urine from splashing and improve the surface cleanliness of the sampler. Attached Figure Description

[0026] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0027] Please see Figures 1-9 A urine sampling device includes a main body 1, a sampler body 6, a splash shield 10, a switching mechanism 11, and an adjustment mechanism 20. A rotating shaft 2 is rotatably connected to the top of the main body 1. A conversion block 3 is fixedly connected to the top of the rotating shaft 2. The switching mechanism 11 is located at the bottom of the rotating shaft 2. A mounting plate 4 is fixedly connected to the outer wall of the conversion block 3. A connecting rod 5 is detachably connected to the inner wall of the mounting plate 4. One end of the connecting rod 5 is fixedly connected to the sampler body 6. An infusion tube 16 is detachably connected to the bottom of the sampler body 6. A collector 17 is fixedly connected to one end of the infusion tube 16. The adjustment mechanism 20 is located at the top of the collector 17. The switching mechanism 11 includes a sector gear 1102 and a connecting gear 1103. A first motor 1101 is located at the top of the main body 1. The output end of the first motor 1101... A sector gear 1102 is fixedly connected, and a connecting gear 1103 that is rotatably connected to the top of the main body 1 of the device meshes with the outer wall of the sector gear 1102. The adjusting mechanism 20 includes a first worm gear 2003, a second worm gear 2004, a sampling tube 2007, and a sector plate 2010. A connecting plate 19 is fixedly connected to the top of the collector 17. The first worm gear 2003 is rotatably connected to the outer wall of the connecting plate 19. A connecting shaft 2005 is fixedly connected to the rotation center of the first worm gear 2003. A placement plate 2006 is fixedly connected to the outer wall of the connecting shaft 2005. A sampling tube 2007 is inserted into the inner wall of the placement plate 2006. The second worm gear 2004 is rotatably connected to the outer wall of the connecting plate 19. During the rotation of the second worm gear 2004, a sector plate 2010 located inside the collector 17 is fixedly connected to it through a rotating shaft.

[0028] The working principle described above is as follows: When collecting urine from patients with the assistance of a sampler, the cross-shaped mounting plate 4 and the sampler body 6 distributed around the mounting plate 4 allow for simultaneous urine collection from multiple patients. It also enables switching between samplers for different patients and centralized replacement of urine collectors, preventing frequent changes to individual samplers and reducing the complexity of collecting urine from different patients. The placement plate 2006 and the fan-shaped plate 2010 rotate synchronously and intermittently. To improve the convenience of automatically transferring urine from the bottom of the collector 17 into test tubes at different times and to prevent spillage, the fan-shaped plate 2010 is driven to rotate. Through the connecting shaft 2005, the placement plate 2006 rotates synchronously, moving the test tubes below the discharge pipe 18. This ensures that the storage space at the fan-shaped plate 2010 corresponds to the test tubes at different positions, achieving synchronous collection of urine from different times.

[0029] For details, please refer to the following: Figure 8 A connecting shaft 7 is fixedly connected to the top of the conversion block 3. A connecting rod 8 is fixedly connected to the top of the connecting shaft 7. A first electric push rod 9 is fixedly connected to the outer wall of the connecting rod 8. A splash shield 10 is fixedly connected to the output end of the first electric push rod 9. The splash shield 10 is distributed in an inclined manner, and the outer wall contour of the splash shield 10 is U-shaped. The outer wall contour of the connecting rod 8 is cross-shaped, and the splash shield 10 is set around the connecting rod 8. The outer wall contour of the mounting plate 4 is cross-shaped. The sampler body 6 is provided with four sets of mounting plates 4, and the positions of the four sets of mounting plates 4 are all distributed around the mounting plate 4. The sampler body 6 and the splash shield 10 are set one-to-one. The splash shield 10 forms a lifting structure with the first electric push rod 9 and the connecting rod 8, which is conducive to driving the first electric push rod 9 to drive the splash shield 10 to move up and down along the outer wall of the connecting rod 8, so as to shield the sampler body 6 in use from splashing.

[0030] The present invention provides a urine sampling device. By raising and lowering the anti-splash cover 10, when collecting and sampling urine from a patient through the sampler body 6, the anti-splash cover 10 is driven to descend to shield the outer wall of the sampler body 6. The anti-splash cover 10 is also set at an angle to prevent urine from splashing and to improve the surface cleanliness of the sampler.

[0031] For details, please refer to the following: Figure 4The inner wall of the mounting plate 4 is provided with a slot 12 at the connection point between it and the connecting rod 5. The outer wall of the mounting plate 4 is provided with a nut 13. The inner wall of the nut 13 is threaded with a bolt 14 that is slidably connected to the outer wall of the connecting rod 5. The connection point between the outer wall of the connecting rod 5 and the bolt 14 is provided with a mounting groove 15. The connecting rod 5 and the mounting plate 4 form an installation structure through the bolt 14 and the mounting groove 15. This facilitates the sliding of the bolt 14 along the inner wall of the mounting groove 15, which drives the connecting rod 5 and the mounting plate 4 to engage and install, achieving the effect of synchronously engaging and replacing the sampler body 6 at different positions.

[0032] The present invention provides a urine sampling device that, through the cooperation of bolts 14 and mounting slots 15, allows for the disassembly of connecting rods 5 from mounting plates 4 after multiple samplers have been used, by separating bolts 14 from mounting slots 15. This enables the collection devices around the mounting plates 4 to be disassembled and replaced one by one, improving the efficiency of medical staff in simultaneously disassembling and replacing multiple collection devices at a time.

[0033] For details, please refer to the following: Figure 5 and Figure 6 The bottom of the collector 17 is fixedly connected to a discharge pipe 18 located on the rotation path of the sampling tube 2007. A second motor 2001 is mounted on the outer wall of the connecting plate 19. The output end of the second motor 2001 is fixedly connected to a worm 2002 that meshes with the outer wall of the first worm gear 2003. The worm 2002 and the second worm gear 2004 are mutually meshed. The first worm gear 2003 forms a rotating structure with the connecting plate 19 via the second motor 2001 and the worm 2002. The second worm gear 2004 is connected via the second motor 2001 and... The worm gear 2002 and the connecting plate 19 form a rotating structure, which is beneficial to the driving of the second motor 2001. Through the rotation of the worm gear 2002, the first worm wheel 2003 and the second worm wheel 2004 are driven to rotate synchronously along the outer wall of the connecting plate 19, so as to drive the connecting shaft 2005 and the sector plate 2010 to rotate synchronously and intermittently. The number of storage cavities formed by the sector plate 2010 is the same as the number of sampling test tubes 2007, so as to achieve the effect of separating and storing urine at different time periods, and automatically collecting urine at different time periods into the test tubes.

[0034] In this embodiment, a support plate 2008 is fixedly connected to the bottom of the placement plate 2006, which is in contact with the bottom of the sampling tube 2007. The outer wall contour of the placement plate 2006 is cross-shaped, and the outer wall contour of the fan-shaped plate 2010 is grid-shaped. The outer wall of the fan-shaped plate 2010 forms liquid storage cavities at different positions. The bottom of the collector 17 is provided with a liquid inlet 2009 that communicates with the inner wall of the discharge pipe 18. A second electric push rod 2011 is fixedly connected to the bottom of the collector 17, and the output end of the second electric push rod 2011 is fixedly connected to... The lifting block 2012 is located below the placement plate 2006. The inner wall contour of the sampling tube 2007 is larger than the outer wall contour of the discharge tube 18, and the discharge tube 18 is set on the lifting path of the sampling tube 2007. The sector plate 2010 forms a rotating structure with the collector 17 through the worm 2002 and the second worm wheel 2004, which is conducive to the rotation of the worm 2002. Through the connection of the second worm wheel 2004, the sector plate 2010 is driven to rotate along the inner wall of the collector 17, so as to achieve the effect of separating and storing urine at different time periods.

[0035] The present invention provides a urine sampling device that, through the intermittent rotation of the sector plate 2010, can store the urine in the collector 17 during the collection of the patient's urine. When the sector plate 2010 is driven to rotate within the collector 17, the urine from different time periods of the patient is stored separately within the collector 17, preventing the mixing of urine from different time periods and thus avoiding affecting the accuracy of the patient's urine test data.

[0036] A urine sampling device of the present invention, when it is necessary to collect urine from a single patient through the sampler body 6, turns on the first motor 1101, and drives the connecting gear 1103 to rotate through the rotation of the sector gear 1102. The rotation of the connecting gear 1103 drives the rotating shaft 2 to rotate the conversion block 3 synchronously. Under the connection of the mounting plate 4, the connecting rod 5, which is engaged with the mounting plate 4, rotates synchronously and intermittently. When the sampler body 6 is switched, the first electric push rod 9 can be opened to drive the anti-splash cover 10 to move downward. The anti-splash cover 10, which is set in an inclined position, is sleeved on the outer wall of the sampler body 6 to prevent urine from splashing. When urine is collected from the sampler body 6, the urine flows into the collector 17 through the infusion tube 16. The second motor 2001 is activated, and the rotation of the worm gear 2002 drives the first worm wheel 2003 and the second worm wheel 2004 to rotate synchronously. The rotation of the second worm wheel 2004 causes the sector plate 2010 to rotate intermittently along the inner wall of the collector 17, dividing the sector plate 2010 into different liquid storage chambers within the collector 17. The intermittent rotation of the sector plate 2010 allows urine from different storage chambers at different times to pass through the infusion port. The sample tube 2009 is fed into the discharge tube 18. Under the rotation of the first worm gear 2003, the rotation of the connecting shaft 2005 drives the placement plate 2006 and the sector plate 2010 to rotate synchronously and intermittently. This causes the sampling tube 2007 to rotate synchronously with the sector plate 2010, and opens the second electric push rod 2011, which drives the lifting block 2012 to rise. This allows the sampling tube 2007 to be inserted into the outer wall of the discharge tube 18. Urine from different time periods is intermittently discharged from the infusion port 2009 and then collected and stored, improving the efficiency of urine automatically entering the test tube for testing.

[0037] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
