[0030] Example 1

[0031] This embodiment provides a medical precision urine flow rate detector, as shown in the attached Figure 1 As shown, it includes a movable tripod 1, a support pole 2 vertically arranged on the tripod, a control terminal 3 arranged on the top of the support pole, and a weighing platform 4, a urine collecting cup 5, and a urine receiving hopper 7 arranged on the support pole from bottom to top. The weighing platform 4 is communicatively connected to the control terminal 3. During the process of collecting urine in the urine collecting cup, the weight change of urine is detected in real time through the weighing platform, and then the patient's urine volume and urine flow rate are calculated through the control terminal.

[0032] As urine descends, it is affected by gravity, the kinetic energy (J1) converted from potential energy, and the kinetic energy (J2) of the urine itself. When the urine contacts the weighing platform, the weighing platform is not only affected by the gravity (g) of the urine itself, but also by the impact force (J1+J2) brought by the urine. This causes a large error in the test results. In order to improve the detection accuracy of the instrument, this embodiment sets a urinary catheter 6 between the urine receiving hopper 7 and the urine collecting cup 5. Figure 2 As shown, one end of the urinary catheter 6 is connected to the urine receiving hopper 7, and the other end is placed at the mouth of the urine collection cup 5 and extends into the urine collection cup. The inner wall of the urinary catheter 6 is provided with a plurality of buffer sheets 6.1 arranged in a zigzag pattern, which can attenuate the flow rate of urine. Furthermore, a drainage rod 5.1 is provided in the middle of the urine collection cup 5. The top of the drainage rod 5.1 is directly opposite the outlet of the urinary catheter 6 (non-contact). After the urine flows out of the urinary catheter, it flows along the drainage rod into the urine collection cup. This design effectively solves the problem of inaccurate test results caused by urine impacting the counterweight, thereby making the test results more accurate.

[0033] Preferably, as attached Figure 1 As shown, the weighing platform 4 is movably mounted on the support rod via a tray frame 8 and secured with locking bolts, allowing for real-time weighing of the urine collection cup. Similarly, the urine collection hopper 7 and urinary catheter 6 are movably mounted on the support rod via a urinal frame 9 and a urinary catheter frame 10, respectively, and secured with locking bolts. This design facilitates adjustment of the position of the weighing platform, urine collection hopper, and urinary catheter on the support rod.

[0034] Preferably, as attached Figure 1 As shown, the urinal hopper 7 is an upwardly tilted opening with an inverted conical urination nozzle at its bottom. The top of the urinary catheter 6 is provided with an inverted conical socket 6.2, and the urinary nozzle of the urinary hopper is plugged into the socket of the urinary catheter. This design allows the urinary hopper and the urinary catheter to be fully coupled.

[0035] Preferably, the length of the urinary catheter 6 is 20 to 50 cm, preferably 30 cm, and the inner diameter is 3 to 10 cm, preferably 5 cm, which can fully accommodate the physiological maximum unit urine flow of 25 ml for adult males.

[0036] Preferably, the drainage rod 5.1 is cylindrical with a diameter of 2 to 5 cm, preferably 3 cm. The drainage rod can be solid or hollow with a sealed top. Hollow rods require less raw material and are more cost-effective. The drainage rod can be integrally formed with the urine collection cup or can be a separate, plug-in structure. This structure requires an insert at the bottom of the cup.

[0037] Preferably, the inner wall of the urinary catheter 6 is sprayed with a non-stick coating (not shown in the figure), which can be a polytetrafluoroethylene coating. This design can prevent the liquid from hanging on the inner wall of the urinary catheter.

[0038] Preferably, the urine receiving bowl 7 and the urine collecting cup 5 are made of disposable paper cups or plastic cups, so that the detection process is clean and hygienic.

[0039] Preferably, as shown in the accompanying Figure 1 and the accompanying Figure 3 The control terminal 3 includes a master control chip 3.1, a power management module 3.2 electrically connected to the master control chip, a weighing signal acquisition module 3.3, an operation button 3.4, an RTC clock module 3.5, a communication module 3.6, a signal indicator light 3.7, and a printing module 3.8. The power management module includes a charging circuit and an energy storage circuit, which are electrically connected to the master control chip. The weighing signal acquisition module is electrically connected to the weighing platform for real-time collection of weighing data of the weighing platform and feedback to the master control chip. The operation button includes a detection start button and a detection end button for manual operation during detection. The communication module includes a combination of one or more of a Bluetooth module, a WiFi module, and a 4G / 5G module, so that the control terminal is connected with the workstation to realize the collection and archiving of patient information. The signal indicator light is used to indicate the working state or mode. The printing module is integrally arranged with the control terminal or independently arranged on the support rod for printing the detection results. In this embodiment, the printing module is integrally arranged with the control terminal.

[0040] Embodiment Two

[0041] Based on the first embodiment, as shown in the accompanying Figure 3 The control terminal 3 of the present embodiment further includes a voice recognition module 3.9 electrically connected to the master control chip 3.1 for voice control of the control terminal. The voice recognition module accesses the national mainstream dialect library, including 23 dialects such as Beijing dialect, Cantonese, Hakka, Guizhou dialect, and Hunan dialect (Changsha), which is convenient for patients with older age, low cultural level, and non-standard Mandarin. This design allows patients to detect without touching the instrument, effectively preventing cross-infection between patients due to contact with the instrument.

[0042] In this embodiment, the control terminal is provided with a urine flow rate mode and a urine volume mode, which are indicated by different signal indicator lights, and supports voice mode switching. When in the urine volume mode, it can be used with a urine bag to obtain the total amount of urine of the patient. The language instructions that can be recognized by the voice recognition module include "start detection", "end detection", "urine flow rate mode", and "urine volume mode", and the corresponding time of the instructions is within 3 seconds.

[0043] In specific use, the patient first fixes the urine receiving bowl on the urine receiving bowl support, and then places the urine collecting cup on the weighing table. During detection, the patient uses the specified language instruction "detection start" to instruct the instrument to perform detection work, the working indicator light of the instrument starts to flicker, the patient urinates against the urine receiving bowl, the urine flows through the urine receiving bowl, attenuates the flow rate through the catheter, and then is collected in the urine collecting cup under the drainage of the drainage rod. During the urine collecting cup collecting the urine, the weighing table detects the weight change of the urine in real time, so as to calculate the urine volume and the urine flow rate of the patient through the main control chip. After the detection is completed, the patient uses the specified language instruction "detection end" to instruct the instrument to end the detection work, and the detection data is automatically printed out through the printer. When the voice function fails, the patient can manually press the operation button to complete the detection.

[0044] The above is only an embodiment of the present application, and does not limit the patent range of the present application, and any equivalent structure or equivalent process transformation, or direct or indirect application in other related technical fields, is also included in the patent protection range of the present application.
