[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figures 1-7 The present invention provides a 24-hour urine collection and measurement device for patients, comprising: a urine measurement component 1, which includes a barrel 110, a controller 120 fixedly connected to the outer wall of the barrel 110, and a weight sensor 130 connected to the inner bottom surface of the barrel 110 by screws, a tray 140 connected to the top of the weight sensor 130, and a disposable urine container 150 placed on the top surface of the tray 140.

[0029] The bucket lid assembly 2 includes a bucket lid body 21. A flap 22 is rotatably connected to the top of the bucket lid body 21 via a pin. A gear ring 23 is meshed with the side of the flap 22. A drive gear 24 is meshed with the outer circumference of the gear ring 23. A shaft 25 is snapped into the inside of the drive gear 24. A drive mechanism is driven to the bottom of the shaft 25. An arc-shaped limiting block 26 is fixedly connected to the top and bottom surfaces of the gear ring 23. A cover plate 27 is connected to the top of the bucket lid body 21 via screws. A flared mouth 28 is fixedly connected to the top center of the cover plate 27.

[0030] Furthermore, two protrusions are fixedly connected to the outer wall of the barrel body 110, and a handle 160 is rotatably connected inside the two protrusions. The top of the barrel body 110 is fastened with a barrel lid body 21. A round hole is opened through the center of the top surface of the barrel lid body 21 and the cover plate 27. A flared mouth 28 is fixedly connected to the round hole at the center of the top surface of the cover plate 27.

[0031] During the 24-hour urine collection process, firstly, after opening the lid body 21, a disposable urine container 150 is placed inside the container body 110 and then placed on the tray 140. Several limiting baffles are integrally connected to the top of the tray 140, which can cover the disposable urine container 150 to prevent it from shifting during use and to facilitate the removal of the disposable urine container 150 after urine collection is completed. When the patient needs to urinate, the handle 160 can be lifted to lift the entire device. When the five flaps 22 are in the open and closed state, male patients can urinate directly from the flared opening 28, while female patients can insert the disposable urinal 11 into the flared opening 28 to urinate. In this way, the urine falls into the disposable urine container 150 through the round tube at the bottom of the lid body 21 for storage. Each urination is stored in the disposable urine container 150, and all urine can be collected until the end of 24 hours.

[0032] Furthermore, four weight sensors 130 are connected to the inner bottom surface of the barrel 110 by screws. The four weight sensors 130 are evenly distributed around the circumference of the barrel 110, and the elastic body of the weight sensor 130 is fixedly connected to the bottom of the support plate 140.

[0033] Furthermore, the controller 120 includes a housing fixedly connected to the outer wall of the barrel 110. The housing contains a main board 121, and a display screen 122 is embedded in the top of the housing. The top of the main board 121 integrates a microcontroller 123, a real-time clock module 124, a data storage module 125, and a signal conditioning module 126. The top of the housing has a control button and a power button.

[0034] The controller 120 can be powered on via the control button. When the patient urinates into the disposable urine container 150, the change in urine weight will cause the weight sensor 130 to generate a corresponding signal. This signal is first transmitted to the signal conditioning module 126, which processes and optimizes the original signal before sending it to the microcontroller 123. At the same time, the real-time clock module 124 on the motherboard 121 will acquire the current time information in real time and transmit it synchronously to the microcontroller 123. After receiving the weight signal and the time signal, the microcontroller 123 converts the weight signal into the corresponding urine volume. Based on preset parameters such as water density and associated with time data, a measurement result and time record for a single urination are generated. On the other hand, the data of this urination is stored in the data storage module 125, and the single urination volume, recording time and cumulative total are displayed in real time on the display screen 122. As the patient urinates multiple times within 24 hours, the weight sensor 130 continuously detects the change in urine weight each time, and the microcontroller 123 continuously receives, processes and stores the measurement and time data for each time, and updates the cumulative total in real time, finally completing the measurement, time recording and total volume statistics for each urination within 24 hours.

[0035] Furthermore, a charging port is provided on the outer wall of the housing, and a battery and power module are installed inside the housing. The signal output terminal of the weight sensor 130 is electrically connected to the signal conditioning module 126 through a wire, and the output terminal of the signal conditioning module 126 is connected to the signal input terminal of the microcontroller 123.

[0036] In this 24-hour urine collection and measurement device, the charging port on the outer wall of the casing, in conjunction with the internal battery and power module, is designed to provide a continuous and flexible power supply for stable operation. The charging port, as an external power input interface, allows the battery to be recharged via an external power source when its charge is low, ensuring the device does not stop working due to power outages and meeting the needs of uninterrupted 24-hour urine collection and measurement. The internal battery stores electrical energy, which powers the mainboard 121 of the controller 120 and the display in scenarios without an external power source (such as when the device is used by a mobile patient). The power supply provides power to all electrical components, including the screen 122, weight sensor 130, and micro motor 4 of the drive mechanism, ensuring that each component functions normally and preventing data loss or device malfunction due to power outages. The power module, on the other hand, plays the role of power conversion and voltage stabilization. It can convert the electrical energy output from the external power supply or battery into voltage and current specifications that meet the working requirements of each electrical component and provide stable power supply. This prevents damage to precision electronic components such as the microcontroller 123 and real-time clock module 124 in the controller 120 due to voltage fluctuations, thus ensuring the accuracy of the device's measurement and the reliability of its operation.

[0037] Furthermore, the top of the motherboard 121 also integrates a Wi-Fi module 127. The microcontroller 123 is bidirectionally electrically connected to the display screen 122, the real-time clock module 124, the data storage module 125, and the Wi-Fi module 127. The Wi-Fi module 127 is used to upload data to the host computer.

[0038] The host computer can centrally receive and store data such as the patient's urine output each time, corresponding time records, and 24-hour cumulative total transmitted by the device. This eliminates the need for medical staff to manually go to the patient's side to check the device's display screen 122 and retrieve information from the data storage module 125, significantly reducing manual operation costs and greatly improving the efficiency of data collection and processing. At the same time, the host computer facilitates unified management, analysis, and traceability of data. Medical staff can quickly retrieve urine data from different time periods to compare changes in the patient's condition, providing more timely and accurate reference for disease diagnosis and treatment plan adjustments.

[0039] Furthermore, the top of the lid body 21 is rotatably connected to five petals 22 via a pin. The five petals 22 are evenly distributed around the circumference of the lid body 21. The top surface of the cover plate 27 is provided with five arc-shaped grooves around its circumference, and an arc-shaped limiting block 26 is slidably connected in each arc-shaped groove.

[0040] Furthermore, the drive mechanism includes a motor housing 3 fixedly connected to the inner wall of the barrel 110, a micro motor 4 installed inside the motor housing 3, a sleeve 5 fixedly connected to the output shaft of the micro motor 4, a transmission shaft head 6 inserted into the sleeve 5, a first synchronous pulley 7 fixedly connected to the top of the transmission shaft head 6, a synchronous belt 8 drivingly connected to the outer surface of the first synchronous pulley 7, and a second synchronous pulley 9 drivingly connected to the inner surface of the synchronous belt 8.

[0041] Furthermore, a cover 10 is provided on the outer surface of the first synchronous pulley 7, the synchronous belt 8, and the second synchronous pulley 9. The cover 10 is connected to the bottom of the bucket cover body 21 by screws, and the top of the second synchronous pulley 9 is fixedly connected to the shaft 25.

[0042] After fastening the lid body 21 onto the barrel body 110 and inserting the drive shaft head 6 into the sleeve 5, pressing the control button on the top of the controller 120 starts the micro motor 4. The output shaft of the micro motor 4 drives the sleeve 5 to rotate. Because the drive shaft head 6 and the sleeve 5 are inserted and engaged, the sleeve 5 will synchronously drive the drive shaft head 6 to rotate. The first synchronous wheel 7 at the top of the drive shaft head 6 will rotate accordingly. The first synchronous wheel 7 drives the second synchronous wheel 9 to rotate through the synchronous belt 8. The top of the second synchronous wheel 9 is fixedly connected to the shaft 25, which in turn drives the drive gear 24, which is engaged inside, to rotate. Since the drive gear 24 meshes with the outer circumferential surface of the gear ring 23, the drive gear 24 will drive the gear ring 23 to rotate. The arc-shaped limiting blocks 26 on the top and bottom surfaces of the gear ring 23 will slide in the arc-shaped groove of the cover plate 27 to ensure that the gear ring 23 is rotated. The device rotates stably, and the toothed ring 23 engages with the five flaps 22 on the sides. The rotation of the toothed ring 23 drives the five flaps 22, which are evenly distributed around the circumference of the lid body 21, to rotate around the pin shaft. Eventually, the five flaps 22 separate and open, thereby opening the round hole at the top of the lid 27 and the lid body 21. The patient can then urinate through the flared opening 28 (or the disposable urinal 11 inserted into the flared opening 28). Conversely, when it is necessary to close the flaps 22, the micro motor 4 is reversed by operating the control button again. The above transmission structure will operate in reverse, driving the toothed ring 23 to rotate in the opposite direction. This causes the five flaps 22 to come closer to each other until they are joined and closed, sealing the round hole at the top of the lid 27 and the lid body 21, and also sealing the bottom of the flared opening 28, preventing the spread of urine odor in the disposable urinal 150.

[0043] Furthermore, a disposable urinal 11 can be inserted into the inside of the flared opening 28, and an operation flowchart 12 is affixed to the top of the lid body 21.

[0044] By attaching the operation flowchart 12 to the top of the lid 21, the educational work of medical staff can be significantly facilitated, effectively reducing the pressure of education and improving the effectiveness of education. First, the operation flowchart 12 can present the key operation steps of 24-hour urine collection (such as the placement of the disposable urine container 150, the use of the disposable urine chamber 11, the operation of the control buttons, and the handling after urine collection) in an intuitive and clear visual form. If patients forget the previous verbal instructions from medical staff while using the device, they can quickly recall the key points of operation by referring to the flowchart at any time without having to repeatedly consult medical staff, greatly reducing the workload of medical staff in answering questions repeatedly. Second, for medical staff who manage multiple patients at the same time, there is no need to give detailed verbal instructions to each patient. They only need to give brief reminders based on the flowchart to let patients understand the operation procedures, which can significantly save education time and improve work efficiency.

[0045] In use, first prepare the device by opening the lid body 21, taking a disposable urine container 150 and placing it inside the container body 110, then placing it on the tray 140. The limiting baffle at the top of the tray 140 will cover the disposable urine container 150 to prevent displacement. Then, fasten the lid body 21 back onto the top of the container body 110, while ensuring that the drive shaft head 6 is inserted into the sleeve 5. Next, turn on the controller 120 using the power button on the top of the controller 120. If the battery power is insufficient, it can be charged through the charging port on the outer wall of the casing to ensure a stable power supply to the device. When the patient needs to urinate, press the control button. The control button on the top of the device 120 starts the micro motor 4. The micro motor 4 drives the drive gear 24 to rotate through the sleeve 5, drive shaft head 6, first synchronous pulley 7, synchronous belt 8, second synchronous pulley 9 and shaft 25. The drive gear 24 drives the gear ring 23 to rotate. The gear ring 23 then drives the five petals 22 to rotate around the pin until they separate and open, opening the round hole on the top of the cover plate 27 and the bucket lid body 21. Then, the handle 160 is lifted to perform the urination operation. Male patients can urinate directly from the funnel 28, while female patients insert the disposable urinal 11 into the funnel 28 to urinate. The urine flows through the bucket lid body. The round tube at the bottom of 21 falls into the disposable urine container 150 for storage; after urination, pressing the control button again controls the micro motor 4 to reverse, which drives the gear ring 23 to rotate in the opposite direction through the above transmission structure, causing the five petals 22 to move closer to each other until they are spliced ​​and closed, sealing the round hole at the top of the cover plate 27 and the lid body 21 to prevent the spread of urine odor; after each urination, the weight sensor 130 detects the change in urine weight and generates a signal. The signal is processed by the signal conditioning module 126 and transmitted to the microcontroller 123. At the same time, the real-time clock module 124 transmits the current time information to the microcontroller 123, and the microcontroller 123 converts the weight signal. The urine volume data is correlated with time data to generate a single urine volume measurement result and time record, which is stored in the data storage module 125. The single urine volume, recording time, and cumulative total are displayed in real time on the display screen 122. During this process, the data is uploaded to the host computer via the Wi-Fi module 127, and medical staff can access the data at any time. If the patient forgets the operation steps, they can refer to the operation flowchart 12 pasted on the top of the lid body 21 to obtain key operation guidance. After the 24-hour urine measurement is completed, the disposable urine container 150 is taken out after opening the lid body 21, completing the entire 24-hour urine collection and measurement process.
