[0002] Uric acid is the final product of purine metabolism in the human body and is mainly excreted through the kidneys. Both high and low uric acid levels can indicate several health problems, such as simple hyperuricemia, gout, nephritis, liver necrosis, and Wilson's disease. Clinical symptoms of uric acid may not be obvious; many patients with hyperuricemia may remain asymptomatic for years, posing a significant challenge to early detection of abnormal uric acid levels.

[0003] In recent years, the age of patients with abnormal uric acid has been gradually decreasing, with more and more young people experiencing abnormal uric acid levels. Excessive consumption of high-purine foods such as hot pot, barbecue, seafood, and animal organs, as well as unhealthy lifestyle habits such as excessive alcohol consumption, are major contributing factors to the increasing number of young people with abnormal uric acid.

[0055] Reference manual attached Figures 1 to 9 This application provides a wearable finger device with uric acid measurement function. The wearable finger device can measure human uric acid in a non-invasive manner when worn on a human finger, and has the advantages of being easy to use and having high measurement efficiency.

[0056] Specifically, the wearable finger device 100 with uric acid measurement function includes a device body 10, an optical sensor 20, a moisture detection sensor 30, a circuit board 40, a power module 50, and a communication module 60.

[0057] The device body 10 surrounds and forms a wearing channel 11. The device body 10 includes a first housing 121 and a second housing 122. The first housing 121 surrounds and forms a mounting cavity 120. The mounting cavity 120 has a mounting opening 1201 facing the wearing channel 11. The second housing 122 is mounted at the mounting opening 1201.

[0058] The optical sensor 20 includes a light-emitting module 21 and a light-receiving module 22, both of which are installed in the mounting cavity 120. The light-emitting module 21 can emit initial light to the wearer's finger, and the light-receiving module 22 can receive the received light after the initial light passes through the finger.

[0059] The moisture detection sensor 30 is installed in the mounting cavity 120. The second housing 122 has a detection opening corresponding to the optical sensor 20 and the moisture detection sensor 30. The moisture detection sensor 30 can detect the moisture content of the wearer's fingers.

[0060] The circuit board 40 and the power module 50 are mounted in the mounting cavity 120. The power module 50 is electrically connected to the circuit board 40, and the circuit board 40 is electrically connected to the optical sensor 20 and the moisture detection sensor 30. The first communication module 60 is mounted in the mounting cavity 120 and connected to the optical sensor 20 and the moisture detection sensor 30. It can transmit the spectral data of the received light and the moisture content to the smart device 200, which calculates the uric acid content based on the received light and the moisture content.

[0061] In this application, the optical sensor 20 is capable of emitting light of a specific wavelength. Uric acid has a characteristic absorption peak in the specific wavelength range. When light of a specific wavelength passes through a liquid containing uric acid, some of the light is absorbed by uric acid molecules. The degree of light intensity attenuation (absorption) is proportional to the concentration of uric acid. The concentration of uric acid can be predicted by the change in light intensity between the received light and the initial light.

[0062] In this application, the moisture detection sensor 30 can detect the moisture content of the wearer's fingers, which can help eliminate the influence of different finger moisture contents on the measurement results during uric acid measurement and improve the accuracy of uric acid measurement results.

[0063] In this application, the wearable finger device, after acquiring the spectral data of the received light and the moisture content of the human finger, can send the acquired data to the smart device 200 via the first communication module 60. The smart device 200 then processes the data, effectively reducing the size of the wearable finger device and contributing to its miniaturization. Preferably, the first communication module 60 is Bluetooth. During use, the first communication module 60, implemented as Bluetooth, can establish a communication connection with the second communication module 201 of the smart device 200 and transmit data. The wearable finger device 100 can send the spectral data of the initial light and the moisture content to the smart device 200. The smart device 200 can determine the uric acid measurement value in the wearer's blood based on the changes in the light intensity of the initial light and the received light, and can correct the uric acid measurement value based on the moisture content to generate the uric acid calibration value.

[0064] Preferably, the first housing 121 is a rigid housing made of materials including stainless steel, titanium alloy, and / or plastic; the second housing 122 is a flexible housing made of materials including rubber. The second housing 122 is located close to the wearing channel 11 and will come into contact with the wearer's fingers during wear. Making the second housing 122 a flexible housing improves the wearer's comfort. The first housing 121 is located away from the wearing channel 11 relative to the second housing 122. Making the first housing 121 a rigid housing improves the structural strength of the device body 10.

[0065] refer to Figure 4The second housing 122 has a contact end 1221 near the wearing channel 11 and a mounting end 1222 near the first housing 121. Each side of the mounting end 1222 has a limiting groove 1223. Each side of the first housing 121 near the mounting opening 1201 has a limiting protrusion 1211, which abuts against the limiting groove 1223. In other words, in this application, the first housing 121 and the second housing 122 are connected to each other by a snap-fit ​​mechanism. In some preferred embodiments, the first housing 121 and the second housing 122 can also be fixedly connected by adhesive bonding. The specific connection and fixing method of the first housing 121 and the second housing 122 should not constitute a limitation of this application.

[0066] The power module 50 includes multiple power blocks 51 connected in series. These power blocks 51 are connected by wires 52 and are arranged in an orderly manner within the mounting cavity 120 along the curved contour of the first housing 121. The series connection of the power blocks 51 allows them to be arranged approximately along an arc, thus aligning them roughly with the arc contour of the wearable device. This allows for the installation of a larger number of power blocks 51 within the wearable device, thereby improving its battery life. Furthermore, the series connection of the power blocks 51 with the wires 52 enables the power module 50 to have a certain degree of deformation capability. This allows the power module 50 to deform along with the device body 10 during wear, thereby improving its structural strength.

[0067] refer to Figure 1 Preferably, the device body 10 is a closed annular structure. (See reference) Figure 2 In one modified embodiment, the device body 10 has a notch 15 at a preset position, so that the device body 10 can undergo a certain deformation during the wearing process, and can adapt to wearers with different finger diameters.

[0068] Specifically, the moisture detection sensor 30 includes a sensor 31, a first electrode 32 and a second electrode 33 respectively connected to the sensor 31. The sensor 31 is installed in the mounting cavity 120, and the first electrode 32 and the second electrode 33 are installed at a preset distance on the side of the second housing 122 near the wearing channel 11. Preferably, the moisture detection sensor 30 is a sensor that measures skin moisture based on the conductivity principle. During wear, the first electrode 32 and the second electrode 33 will come into contact with the wearer's skin. The sensor 31 can generate an alternating current signal of a specific frequency, and the moisture content can be determined by the change in conductivity. Optionally, in some modified embodiments, the moisture detection sensor 30 can also be a structure that measures moisture based on the capacitance principle. The specific measurement principle adopted by the moisture detection sensor 30 should not constitute a limitation of this application.

[0069] refer to Figure 3 and Figure 4 The wearable finger device includes a mounting frame 70, the optical sensor 20 and the moisture detection sensor 30 are respectively fixed to the mounting frame 70, and the mounting frame 70 is installed in the mounting cavity 120.

[0070] The optical sensor 20 and the moisture detection sensor 30 are respectively mounted on the mounting bracket 70. During installation, the optical sensor 20, the moisture detection sensor 30, and the mounting bracket 70 can be assembled into a single unit outside the mounting cavity 120 and then installed inside the mounting cavity 120, effectively improving the convenience of the installation process. Furthermore, fixing the optical sensor 20 and the moisture detection sensor 30 to the mounting bracket 70 improves the stability of their installation.

[0071] refer to Figure 1Further, the light-emitting module 21 includes a first light-emitting module 211, a second light-emitting module 212, and a third light-emitting module 213 arranged at intervals. The first light-emitting module 211 emits a first initial light with a first wavelength, the second light-emitting module 212 emits a second initial light with a second wavelength, and the third light-emitting module 213 emits a third initial light with a third wavelength. Preferably, the first light-emitting module 211 emits the first initial light with a wavelength in the range of 800nm ​​to 1000nm, the second light-emitting module 212 emits the second initial light with a wavelength in the range of 1100nm to 1400nm, and the third light-emitting module 213 emits the third initial light with a wavelength in the range of 1400nm to 1500nm. Preferably, the first light-emitting module 211, the second light-emitting module 212, and the third light-emitting module 213 are all LEDs, such as, but not limited to, OLEDs and Micro LEDs. The light-receiving module 22 includes a photodiode array capable of capturing changes in reflected light intensity.

[0072] refer to Figure 6 The device body 10 has a palm-side segment 131 and a back-of-the-hand segment 132. After the wearable device is worn on the finger 1001, the palm-side segment 131 contacts the palmar side of the finger, and the back-of-the-hand segment 132 contacts the dorsal side of the finger. The portion of the palm-side segment 131 away from the back-of-the-hand segment 132 has a receiving segment 1311. The radius of the arc of the receiving segment 1311 is smaller than the radius of the arc of the palm-side segment 131, and the receiving segment 1311 forms a receiving groove 130.

[0073] The light-emitting module 21 and the light-receiving module 22 are respectively located on both sides of the accommodating segment 1311. For example, the light-emitting module 21 is located on the left side of the accommodating segment 1311, and the light-receiving module 22 is located on the right side of the accommodating segment 1311. In some modified embodiments, the light-emitting module 21 is located on the right side of the accommodating segment 1311, and the light-receiving module 22 is located on the left side of the accommodating segment 1311.

[0074] After the wearable device is worn on the finger, at least a portion of the tissue on the palmar side of the finger can be accommodated in the receiving groove 130 and located in the propagation path of the light emitted by the light-emitting module 21. By setting the receiving groove 130, the amount of human tissue located in the propagation path of the light emitted by the light-emitting module 21 can be increased, thereby increasing the accuracy of the measurement results.

[0075] refer to Figure 7Furthermore, the wearable finger device further includes an electrochemical sweat sensor 71 installed on the back of the hand 132 and an acceleration sensor 72 installed on the device body 10. The electrochemical sweat sensor 71 and the acceleration sensor 72 are electrically connected to the circuit board 40, respectively. The electrochemical sweat sensor 71 is used to measure the uric acid content in the wearer's sweat, and the acceleration sensor 72 is used to measure the wearer's movement state.

[0076] After the finger wearable device is worn on a human finger, the palmar side segment 132 contacts the human tissue on the back of the hand of the finger, and the palmar side segment 131 contacts the human tissue on the palmar side of the finger. Setting the electrochemical sweat sensor 71 on the palmar side segment 132 allows the electrochemical sweat sensor 71 to directly contact the area with hair on the back of the human finger, which facilitates the electrochemical sweat sensor 71 in measuring the uric acid content in human sweat.

[0077] The accelerometer 72 can measure the wearer's movement state. Since the wearer is more prone to sweating during exercise, the measurement frequency of the electrochemical sweat sensor 71 can be appropriately increased while the measurement frequency of the optical sensor 20 can be decreased. Preferably, the accelerometer 72 is an accelerometer. When the accelerometer 72 measures the wearer's acceleration as greater than a preset value, the wearer is identified as being in motion; when the wearer's acceleration is less than the preset value, the wearer is identified as being in a non-motion state. In some embodiments, the wearable finger device further includes a temperature sensor and a heart rate sensor installed on the device body 10 to obtain the wearer's temperature and heart rate data.

[0078] Furthermore, the outer side of the wearable finger device has a first charging contact 73, which is electrically connected to the power module 50, and the power module 50 can be charged through the first charging contact 73.

[0079] Preferably, the wearable finger device 100 provided in this application includes, but is not limited to, a ring. The smart device 200 includes, but is not limited to, mobile phones, tablets, smartwatches, smart bracelets, AI glasses, AR / VR devices, and other smart devices. (Reference) Figure 5 and Figure 8Taking the smart device 200 as an example, implemented as a mobile phone, the display interface of the smart device 200 can display the measurement time, skin moisture, measurement value one (measurement result of optical sensor 20), measurement value two (measurement result of electrochemical sweat sensor 71), and uric acid calibration value (the result after correcting the uric acid value measured by optical sensor 20 based on the human body moisture data obtained by moisture detection sensor 30). For example, at 10:00 AM, the skin moisture value measured by moisture detection sensor 30 is 20%, the measurement result of optical sensor 20 is 300 μmol / L, the measurement result of electrochemical sweat sensor 71 is 310 μmol / L, and the result after correcting the uric acid value measured by optical sensor 20 based on the human body moisture data obtained by moisture detection sensor 30 is 320 μmol / L.

[0080] It is understandable that at the same time point, the optical sensor 20 and the electrochemical sweat sensor may not collect uric acid data simultaneously. In this case, the corresponding area can display the value measured at the previous time or not display it.

[0081] refer to Figure 9 Furthermore, the smart device 200 can statistically analyze historical measurement data and display it in the form of charts. For example... Figure 9 The horizontal axis represents the measurement time, and the vertical axis represents the uric acid value. The length of the bars in the bar chart indicates the value of the uric acid measurement result at a certain time. Figure 9 The illustration only shows historical data of uric acid values ​​obtained by optical sensor 20; the display of historical data of uric acid values ​​obtained by electrochemical sweat sensor 71 is similar. In some embodiments, measurement value one and measurement value two can also be represented by bars of different colors in the same icon.

[0082] refer to Figure 1 A switch 14 is provided on the outer side of the device body 10. The switch 14 is electrically connected to the circuit board 40. The switch 14 can control the power supply module 50 to supply power or stop power supply, thereby controlling the operation of the optical sensor 20 and the moisture detection sensor 30. For example, the switch 14 is turned on before the finger wearable device 100 is needed, and the switch 14 is turned off after use. In some embodiments, the switch 14 can also be a proximity switch, which automatically turns on after being worn on the wearer's finger and automatically turns off after a preset time after being removed from the wearer's finger.

[0083] refer to Figure 10 and Figure 11According to another aspect of this application, a wearable finger device assembly with uric acid measurement function is further provided, including the wearable finger device 100 described in the above embodiments and a charging base 300. The charging base 300 includes a base 301, the base 301 having a battery cavity inside which a rechargeable battery is installed. The top of the base 301 has an annular charging groove 303, and the surface of the annular charging groove 303 has a second charging contact 304 connected to the rechargeable battery.

[0084] When the wearable finger device 100 is installed in the annular charging slot 303, the first charging contact 73 contacts the second charging contact 304, and the rechargeable battery can charge the power module 50 of the wearable finger device.

[0085] In this application, the charging base 300 can complete the charging process of the finger wearable device 100 while storing it, which is convenient for the operator to use.

[0086] Furthermore, one side surface of the base 301, which has the annular charging slot 303, has two pickup slots 305 that communicate with and are disposed opposite to the annular charging slot 303. Preferably, the depth of the annular charging slot 303 is greater than the thickness of the device body 10, so that the device body 10 can be completely housed within the annular charging slot 303. When the device body 10 is placed in the annular charging slot 303, the top of the device body 10 is higher than the surface of the pickup slot 305, so that the operator can easily remove the device body 10 from the annular charging slot 303 through the pickup slot 305.

[0087] refer to Figure 10 and Figure 11 The charging base 300 further includes an opening and closing cover 302 rotatably mounted on the base 301. The opening and closing cover 302 has an open state and a closed state.
