Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of intelligent wear, in particular to a smart ring and a heart sound detection control method. BACKGROUND

[0002] Human heart sound data can be used to determine the health status, and currently, doctors usually use a stethoscope or an electronic auscultation device to collect heart audio data. Doctors determine the health status by experience. The accuracy of data determination depends on the experience of doctors, and the physical condition of each person is different, and there is no standard data display, so the error rate of manual auscultation is high, and accurate judgment is usually not possible.

[0003] In a wrist-worn smart device integrated with a heart sound collection module, the sound pickup hole of the heart sound collection module is arranged to face away from the arm to facilitate sound pickup, which requires the user to hold the dial of the wrist-worn smart device close to the chest wall. However, most users wear the device with the dial facing outward, which means that the user needs to rotate the arm in the opposite direction to make the dial face inward, i.e., the dial faces the chest wall, in order to detect heart sound information each time. In order to ensure the accuracy of the detection results and the reference value of the results, a certain time length needs to be detected each time, so that the wrist and the joint close to the wrist will have a certain soreness. SUMMARY

[0004] The main purpose of the present application is to provide a smart ring, which aims to obtain physiological characteristic information of a user while avoiding arm soreness.

[0005] To achieve the above-mentioned purpose, the smart ring comprises an outer shell and an inner shell, the outer shell is connected with the inner shell and encloses to form an annular accommodating cavity, and the smart ring comprises: a circuit board, the circuit board is arranged in the annular accommodating cavity, and a heart sound collection module is integrated on the side of the circuit board facing away from the inner shell; and a pressure-sensitive component, the pressure-sensitive component is arranged on the circuit board and abuts against the inner wall of the outer shell facing the inner shell. The pressure-sensitive component is configured as a trigger switch of the heart sound collection module.

[0006] In an embodiment of the present application, the inner wall of the outer shell facing the inner shell is provided with a flat section, and one end of the pressure-sensitive component abuts against the side of the flat section facing the inner shell.

[0007] In an embodiment of the present application, the side of the flat section facing the inner shell is provided with a limiting step, the limiting step has a first fixed surface and a second fixed surface which are in connection with each other, the end of the pressure-sensitive component has a first matching surface and a second matching surface which are in connection with each other, the first fixed surface is in limiting cooperation with the first matching surface, and the second fixed surface is in limiting cooperation with the second matching surface.

[0008] In one embodiment of the present invention, two fixing arms are further provided on the inner wall of the outer shell facing the inner shell. The two fixing arms are correspondingly arranged along the thickness of the outer shell, and each fixing arm is fixedly connected to one end of the circuit board.

[0009] In one embodiment of the present invention, the pressure-sensitive component includes a buffer and a pressure-sensitive sensor, and the buffer and the pressure-sensitive sensor are arranged along the radial direction of the smart ring. The buffer and the pressure-sensitive sensor are both located between the circuit board and the outer shell. The pressure-sensitive sensor is provided on the circuit board, and the buffer connects the pressure-sensitive sensor and the inner wall of the outer shell facing the inner shell.

[0010] In one embodiment of the present invention, the pressure-sensitive component includes a buffer and a pressure-sensitive sensor, the buffer and the pressure-sensitive sensor are arranged along the radial direction of the smart ring, the buffer is located between the circuit board and the housing, and the pressure-sensitive sensor is located on a side of the circuit board facing away from the housing; Wherein, the buffer component connects the circuit board and the inner wall of the outer shell facing the inner shell.

[0011] In one embodiment of the present invention, the pressure-sensitive component includes a buffer and a pressure-sensitive sensor, the buffer and the pressure-sensitive sensor are arranged along the radial direction of the smart ring, and the buffer is arranged near the central area of ​​the circuit board.

[0012] In one embodiment of the present invention, the housing of the smart ring is provided with an extrusion indicator portion, and the extrusion indicator portion is arranged corresponding to the buffer component.

[0013] The present invention also provides a heart sound detection and control method for the above-mentioned smart ring, the heart sound detection and control method comprising: receiving a test instruction from the intelligent terminal, and driving the pressure-sensitive component to enter a pressure detection state according to the test instruction; obtaining a pressure detection value of the pressure-sensitive component, and when the pressure detection value is within a preset pressure range, controlling the heart sound collection module to enter a heart sound collection state; Sending first information to the smart terminal according to the detection duration of the pressure-sensitive component.

[0014] In one embodiment of the present invention, after the step of obtaining the pressure detection value of the pressure-sensitive component, the method further includes: When the pressure detection value is not within the preset pressure range, generating an end instruction; According to the end instruction, the heart sound collection module exits the heart sound collection state, and an end instruction is sent to the intelligent terminal, and the end instruction is used to generate pressure adjustment information by the intelligent terminal.

[0015] In the technical solution, the intelligent ring converts the collection of heart sound signals from "manual auscultation by doctors" to "electronic collection by equipment" by integrating the heart sound collection module. The heart sound collection module directly acquires original heart sound data and processes the original heart sound data through a circuit board to output standardized digital signals. When the intelligent ring needs to collect heart sound data in a wearing state, the user only needs to lift the arm and directly paste the side of the outer surface of the ring on the finger to the chest wall where the heart sound collection module is located. Since the outer surface of the finger is outward in the natural wearing state, the finger does not need to be "rotated at the arm / wrist joint" when being pasted to the chest wall. The finger only needs to be kept in the natural posture when the arm is naturally lifted. In this process, the joint and the finger do not need to be rotated, and the heart sound collection module can be tightly pasted to the chest wall. The pressure-sensitive component abuts against the inner wall of the shell and serves as a trigger switch of the heart sound collection module. When the outer surface of the ring is pasted to the chest wall, the chest wall pressure is transmitted to the pressure-sensitive component through the shell to trigger the detection start, so that the adhesion during detection is ensured. At the same time, no additional operation is needed, and the process of "lifting the arm for detection" is further simplified. In summary, the intelligent ring integrates the heart sound collection module, fundamentally eliminates the need to rotate the joint during detection, realizes "lifting the arm for detection without rotating the joint", and completely solves the problem of acid swelling caused by continuous rotation of the joint of the wrist-worn device. At the same time, the electronic collection realizes the standardization of data, and avoids the error problem caused by the dependence on manual experience.

[0022] The main purpose of the present application is to provide a smart ring 100, which aims to achieve the acquisition of physiological feature information of a user while avoiding the feeling of arm swelling.

[0023] To achieve the above-mentioned purpose, please refer to Figure 1The smart ring 100 includes an outer shell 10, an inner shell 11, a circuit board 20 and a pressure-sensitive component 30. The outer shell 10 is connected to the inner shell 11 and encloses an annular accommodating cavity: the circuit board 20 is arranged in the annular accommodating cavity, and the side of the circuit board 20 facing away from the inner shell 11 is integrated with a heart sound collection module; the pressure-sensitive component 30 is arranged on the circuit board 20 and abuts the inner wall of the outer shell 10 facing the inner shell 11; wherein, the pressure-sensitive component 30 is configured as a trigger switch of the heart sound collection module.

[0024] In this technical solution, the smart ring 100 integrates a heart sound collection module, transforming heart sound signal collection from "manual auscultation by a doctor" to "electronic collection by the device." The heart sound collection module directly acquires raw heart sound data, processes it through the circuit board 20, and outputs a standardized digital signal. When the smart ring 100 is worn and heart sound data collection is required, the user simply raises their arm and places the outer surface of the ring on their finger, corresponding to the side where the heart sound collection module is located, directly against the chest wall. Because the outer surface of the finger is facing outward in its natural position, there is no need to "reversely rotate the arm / wrist joint" as required by wrist-worn devices to place the ring against the chest wall. Simply raise the arm naturally and maintain a natural finger position. During this process, the heart sound collection module remains in close contact with the chest wall without rotating the joints or fingers. The pressure-sensitive component 30 abuts the inner wall of the housing 10, acting as a trigger for the heart sound collection module. When the outer surface of the ring is in close contact with the chest wall, chest wall pressure is transmitted through the housing 10 to the pressure-sensitive component 30, triggering detection. This ensures proper fit during testing and eliminates the need for additional operation, further simplifying the "raise arm and test" process. In summary, the smart ring 100 integrates a heart sound collection module, which fundamentally eliminates the need to "rotate joints during detection" and realizes "detection by raising the arm without rotating joints", completely solving the problem of soreness and swelling caused by continuous rotation of joints in wrist-worn devices; at the same time, data standardization is achieved through electronic collection, avoiding the error problem of relying on human experience. Specifically, the outer shell 10 is typically made of a material with a certain degree of hardness and a smooth surface, such as metal or high-strength plastic, to provide structural support and an aesthetically pleasing appearance for the ring. The inner shell 11 is typically made of a softer, skin-friendly material, such as silicone or a special resin, to ensure comfortable wearing and a close fit against the skin of the finger. The outer shell 10 and the inner shell 11 are securely connected together through a precise connection method (such as a snap, threaded connection, or integral molding). Together, they form an annular, hollow housing. This annular housing not only provides physical space for core components such as the circuit board 20, but its annular structure also ensures that the ring can be worn stably on the user's finger.

[0025] Inside the ring-shaped accommodating cavity, there is a circuit board 20, which is the brain of the smart ring 100, carrying various electronic components such as charging columns, filters, amplifiers, etc. In particular, on the side of the circuit board 20 facing the shell 10, there is an integrated heart sound collection module, which usually contains one or more high-sensitivity microphones or vibration sensors, precisely packaged and fixed on the circuit board 20 by SMT technology. It is set on the side facing the shell 10 to more effectively pick up the weak vibration and sound signals generated by the heart beat conducted through the shell 10.

[0026] On the circuit board 20, there is also a pressure-sensitive component 30, which is physically arranged on the circuit board 20 and directly abuts against the inner wall of the shell 10 facing the inner shell 11. This means that when the user's finger is pressed against the chest wall, the shell 10 will undergo a slight deformation or movement, which will be directly transmitted to the pressure-sensitive component 30 abutting against it. The pressure-sensitive component 30 can sense and measure the change in pressure applied to it and convert it into an electrical signal, which is monitored by the control system or control chip on the circuit board 20. When the pressure detected by the pressure-sensitive component 30 reaches or exceeds a certain preset threshold, the control system will receive a "trigger" signal, and then instruct the heart sound collection module to start working and begin collecting heart sound data. Conversely, when the pressure decreases below another threshold, the heart sound collection may stop. This design ingeniously links the user's physical interaction (squeezing the ring) with the process of collecting heart sound data, making it easy for the user to actively initiate detection and possibly recording heart sounds automatically when the user unconsciously squeezes, improving the convenience of use and the richness of data. The entire system is compactly integrated in the ring, a daily wear item, making heart sound monitoring possible without feeling and continuously.

[0027] When the smart ring 100 is in a wearing state, the pressure receiving end of the pressure sensitive component 30 naturally faces away from the palm of the user, and the user only needs to raise the hand to complete the alignment of the pressure receiving end of the pressure sensitive component 30 with the chest wall of the human body, at this time, the wrist joint does not need to be rotated to realize the alignment of the pressure receiving end of the pressure sensitive component 30 with the chest wall of the human body, in this way, the user does not need to perform a wrist rotation action when using the smart ring 100 to collect heart sound signals, in this way, the tension and fatigue of the muscle tissues such as the extensor muscle group and the finger extensor muscle on the forearm can be avoided, further, when it is necessary to adjust the pressure value received by the pressure sensitive component 30, the finger only needs to be rotated in the counterclockwise or clockwise direction, and only the finger joint needs to be powered during the rotation process, as is known to all, the muscle activities of the finger part are limited to the flexor and extensor muscles of the finger and some small muscle groups for fine control, these muscles are relatively small, and the fatigue generated when powered is much smaller than the fatigue generated when the entire forearm muscle group is used to rotate the wrist or adjust the arm posture, thereby avoiding unnecessary muscle tension and fatigue, making long-term wearing and use more comfortable, and the user can focus on the collection of heart sound signals without worrying about the physical burden caused by the operation.

[0028] In another embodiment, the heart sound collection module of the wristband device is located on the side of the watch face facing the arm, and the user does not need to rotate the elbow joint when collecting heart sound signals, but at this time, the heart sound signal transmission path is "heart-internal skeleton-chest wall-wristband-arm-heart sound collection module in watch", and the heart sound signal is weak, and the heart sound signal inevitably weakens when passing through multiple propagation media, resulting in a decrease in the reliability of the detection result; in order to reduce signal weakening, the user can disassemble the wristband device and directly attach the device to the chest wall, but the wristband needs to be disassembled and assembled every time, and once the use frequency of the heart sound mobile module increases, the mechanical wear of the disassembly structure such as the butterfly buckle in the wristband quickly accumulates, resulting in problems such as damage to the wristband, and the smart ring 100 proposed in the present application can perfectly avoid the problems of arm fatigue, rapid weakening of heart sound signals, and inconvenient detection in different dimensions, greatly improving the user experience and the accuracy of the detection result when detecting.

[0029] In an embodiment, please refer to Figure 1In order to ensure that the pressure-sensitive component 30 can obtain a stable and reliable installation basis, the inner wall of the shell 10 facing the inner shell 11 is provided with a flat section 10a, which refers to the protruding part on the inner wall of the shell 10, and the top surface of the flat section 10a facing the inner shell 11 is closer to the inner shell 11. The flat section 10a can be formed in an integrated structure with the shell 10 by injection molding process or other processes. The force receiving end of the pressure-sensitive component 30 abuts against the top surface of the flat section 10a. Through this design, a stable and uniform contact surface can be provided for the pressure-sensitive component 30. When the shell 10 of the smart ring 100 is subjected to the pressure of the chest wall, the pressure can be uniformly transmitted to the pressure-sensitive component 30 through the flat section 10a, avoiding uneven stress caused by possible slight unevenness or curvature change of the inner wall of the shell 10. The provision of the flat section 10a can ensure that the pressure-sensitive component 30 accurately and reliably senses the pressure change, ensuring the stability and consistency of the subsequent heart sound collection module being triggered, effectively avoiding signal drift caused by the arc-shaped inner wall of the shell 10, and improving the reliability of the detection function of the smart ring 100.

[0030] Further, in order to further enhance the positioning accuracy and stability of the pressure-sensitive component 30 on the flat section 10a, prevent unnecessary movement or tilting thereof during use of the ring, and thus affect the accuracy of pressure sensing, please refer to Figure 1 A limiting step 12 is provided on the top surface of the flat section 10a facing the inner shell 11. The limiting step 12 has a first fixed surface 121 and a second fixed surface 122, and the dihedral angle formed by the first fixed surface 121 and the second fixed surface 122 tends to be a right angle, and together constitutes an "L" shape or similar step-like structure. At the same time, the end portion of the pressure-sensitive component 30, i.e. the portion thereof abutting against the flat section 10a, is also designed to have a specific shape to match the limiting step 12. The end portion has a first matching surface and a second matching surface that are connected to each other. The first matching surface is designed to be able to accurately dock or fit with the first fixed surface 121 of the limiting step 12, and the second matching surface is designed to be able to accurately dock or fit with the second fixed surface 122 of the limiting step 12. The first fixed surface 121 and the second fixed surface 122 of the limiting step 12 provide a larger fixed area for the pressure-sensitive component 30, and are fixedly connected by adhesion or the like and closely fit, so as to prevent the pressure receiving end of the pressure-sensitive component 30 from being separated from the shell 10 and failing to effectively sense the pressure from the chest wall.

[0031] In order to ensure the stable installation of the circuit board 20 in the annular accommodating cavity, prevent displacement, looseness or even damage thereof when the ring is worn, the finger moves or is subjected to external impact, please refer to Figure 1In an embodiment, the inner wall of the outer shell 10 facing the inner shell 11 is further provided with two fixing arms 13, which are arranged in correspondence along the thickness direction of the outer shell 10, and each of the fixing arms 13 is fixedly connected to one end of the circuit board 20 by means of adhesion. The two fixing arms 13 provide strong support for the circuit board 20, so that the circuit board 20 remains stable in the dynamic environment of the ring and effectively prevents displacement of the circuit board 20 caused by vibration, bending or extrusion. Secondly, by fixing both ends of the circuit board 20, the position and posture of the circuit board 20 in the annular accommodating cavity can be better controlled, and it is ensured that each element (including the connection points of the heart sound collection module and the pressure-sensitive assembly 30) on the circuit board 20 is in the expected spatial position, which is crucial for ensuring the stability of signal transmission and the accurate operation of the sensor; at the same time, when the smart ring 100 is subjected to pressure from the chest wall, the two ends of the circuit board 20 are fixed, and the action point of the pressure-sensitive assembly 30 on the circuit board 20 is located in the middle part of the circuit board 20, so that the middle part of the circuit board 20 can be deformed in a micro-bending manner greater than the two ends, and when the PIN pin of the pressure-sensitive assembly 30 abuts against the middle part of the circuit board 20, the pressure-sensitive assembly 30 can quickly sense the micro-bending deformation to form an electrical signal, thereby improving the response speed of the pressure-sensitive assembly 30; further, between each of the fixing arms 13 and one end of the circuit board 20, an adhesion layer is arranged, the thickness of the adhesion layer refers to the size of the adhesion layer in the radial direction of the smart ring 100, which ensures stable connection without occupying too much space, the thickness t of the adhesion layer is 0-0.05mm, and at the same time, in order to ensure that the adhesion layer has sufficient area to ensure stable connection, the size of the adhesion layer in the tangential direction perpendicular to the radial direction of the smart ring 100 is W2, which is greater than 0.40mm and does not exceed the width of the fixing arm 13.

[0032] In an embodiment of the present application, please refer to Figure 1 and Figure 3The pressure-sensitive assembly 30 comprises a buffer 31 and a pressure-sensitive sensor 32, the buffer 31 and the pressure-sensitive sensor 32 are arranged along the radial direction of the smart ring 100, the buffer 31 and the pressure-sensitive sensor 32 are both located between the circuit board 20 and the shell 10, the pressure-sensitive sensor 32 is arranged on the circuit board 20, and the buffer 31 is connected to the pressure-sensitive sensor 32 and the inner wall of the shell 10 facing the inner shell 11, wherein the buffer 31 is made of an elastic material such as silica gel, rubber or foam, when the shell 10 of the smart ring 100 is extruded by the chest wall, the slight deformation of the shell 10 can directly act on the buffer 31, the buffer 31 generates a pressure on the pressure-sensitive sensor 32, the pressure-sensitive sensor 32 converts the pressure from the buffer 31 into an electrical signal through the PIN pin, so that the pressure of the chest wall on the smart ring 100 can be captured in the first time, and then it is judged whether the pressure of the chest wall on the smart ring 100 can trigger the heart sound collection module; at the same time, the direct abutment of the buffer 31 and the pressure-sensitive sensor 32 can concentrate the dispersed pressure to the pressure-sensitive sensor 32, so as to ensure that the sensor can stably capture the pressure change; the pressure-sensitive sensor 32 can be a thin film pressure sensor or a piezoelectric sensor, which can convert the pressure signal transmitted by the buffer 31 into an electrical signal, and then trigger the start or stop of the heart sound collection module; based on the above embodiment, the smart ring 100 provided by the application has two deformation transmission paths, the first one is: the shell 10 of the smart ring 100-buffer 31-circuit board 20-pressure-sensitive sensor 32, and the second one is: the shell 10 of the smart ring 100-fixed column arm-circuit board 20-pressure-sensitive sensor 32, the pressure-sensitive sensor 32 can sense the pressure from the chest wall to the greatest extent through the two deformation transmission paths, and reduce the pressure value detection error.

[0033] In another embodiment of the application, please refer to Figure 1 and Figure 4The pressure-sensitive component 30 comprises a buffer 31 and a pressure-sensitive sensor 32, the buffer 31 and the pressure-sensitive sensor 32 are arranged along the radial direction of the smart ring 100, the buffer 31 is located between the circuit board 20 and the shell 10, and the pressure-sensitive sensor 32 is located on the side of the circuit board 20 away from the shell 10; wherein the buffer 31 is connected to the circuit board 20 and the inner wall of the shell 10 facing the inner shell 11, in this embodiment, the buffer 31 is made of an elastic material such as silica gel, rubber or foam, and its two ends are connected to the shell 10 and the side of the circuit board 20 facing the shell 10, and the pressure-sensitive sensor 32 is located on the side of the circuit board 20 away from the shell 10, so that the slight deformation of the buffer 31 caused by the extrusion of the shell 10 of the smart ring 100 is first transmitted to the pressure-sensitive sensor 32 through the slight deformation of the circuit board 20, which can avoid the failure of the pressure-sensitive sensor 32 caused by excessive pressure deformation; at the same time, the buffer 31 and the pressure-sensitive sensor 32 are arranged along the radial direction of the smart ring 100, that is, the deformation of the buffer 31 is directly opposite to the pressure-sensitive sensor 32, so as to ensure that the force from the chest wall can be transmitted to the pressure-sensitive sensor 32 along the radial direction of the smart ring 100, and avoid that the pressure detection value of the pressure-sensitive sensor 32 is much smaller than the actual pressure value of the chest wall to the smart ring 100.

[0034] In order to ensure that the force detected by the pressure-sensitive sensor 32 is close to the actual pressure value, please refer to Figure 1 and Figure 2 In an embodiment of the present application, the pressure-sensitive component 30 comprises a buffer 31 and a pressure-sensitive sensor 32, the buffer 31 and the pressure-sensitive sensor 32 are arranged along the radial direction of the smart ring 100, the buffer 31 is arranged close to the central region of the circuit board 20, in the aforementioned embodiment, the two ends of the circuit board 20 are supported and fixed by the fixed arms 13 of the shell 10, and the middle part of the circuit board 20 is in a suspended state, at this time, the deformation amount of the middle part of the circuit board 20 is gradually reduced to the two ends, and the pressure signal generated in the middle part of the circuit board 20 is the largest, therefore, the buffer 31 is arranged close to the central region of the circuit board 20, and the buffer 31 is arranged opposite to the pressure-sensitive sensor 32, which can ensure that the pressure-sensitive sensor 32 can detect the largest pressure value, and the corresponding digital signal is the closest to the actual pressure value from the chest wall, so that when the user adjusts the chest wall pressure, the pressure-sensitive sensor 32 can be prevented from being damaged; please refer to the accompanying Figure 1 and Figure 2, the "buffer 31 is close to the center region of the circuit board 20" refers to the center line of the buffer 31 along the length direction and the width direction of the circuit board 20 and the distance between the center line of the circuit board 20 and the center line is L and W2, respectively, -1.00mm

[0035] Further, in order to ensure that the user can directly face the chest wall when detecting, the shell 10 of the smart ring 100 is provided with a pressing indication part, and the pressing indication part is arranged corresponding to the buffer 31; wherein the pressing indication part is located in the diameter direction of the smart ring 100, in an embodiment, the pressing indication part is a groove structure on the shell 10 of the smart ring 100, the groove is symmetrically opened in the radial direction, and is arranged along the thickness direction of the smart ring 100 to form an elongated "positioning groove", the bottom of the groove can be anodized and treated, and presents a matte dark color which is obviously distinguished from the body of the shell 10, and forms high contrast in vision, so that it can be quickly identified by the user even in low light environment, and the both ends of the groove adopt circular arc transition to avoid scratching the skin or clothes; when the smart ring 100 is in the wearing state, the pressing indication part is located at the middle line position of the back of the finger, so that when the user picks up the smart ring 100 for wearing, whether the pressing indication part is located at the middle line position of the back of the finger is directly judged by the naked eye, so as to ensure the accuracy of the wearing position.

[0036] The application also provides a heart sound detection control method for the smart ring 100, please refer to Figure 5 , the heart sound detection control method comprises: S10: receiving a test instruction from a smart terminal, and driving the pressure-sensitive component 30 into a pressure detection state according to the test instruction; S20: acquiring a pressure detection value of the pressure-sensitive component 30, and controlling the heart sound collection module to enter a heart sound collection state when the pressure detection value is within a preset pressure range; S30: sending first information to the smart terminal according to the detection duration of the pressure-sensitive component 30.

[0037] In step S10, the smart ring 100 establishes a communication connection with a smart terminal such as a mobile phone or a tablet through a wireless communication mode such as Bluetooth, and the user initiates a heart sound detection request, that is, a "test instruction", on the corresponding application software of the smart terminal; after the controller of the smart ring 100 receives the test instruction, a start signal is sent to the pressure-sensitive component 30, so that the pressure-sensitive sensor 32, the buffer 31 and other components are switched from the standby state to the working state, and the real-time monitoring of the pressure change is started; the function of this step is to establish the association between "user active triggering" and "device response", so as to ensure that the heart sound detection is started only when the user needs it, and to avoid false triggering or invalid power consumption.

[0038] In step S20, after the pressure-sensitive component 30 enters the pressure detection state, the pressure signal is continuously converted into an electrical signal in the form of voltage or current change, and the controller of the smart ring 100 obtains the electrical signal in real time and converts it into a specific pressure value; when the pressure detection value is within the preset range, it indicates that the shell 10 of the smart ring 100 is closely attached to the chest wall, and the electronic elements such as the microphone and the vibration sensor in the heart sound collection module are triggered to start, and the original data of the S1 heart sound, the S2 heart sound and the abnormal heart sound are collected.

[0039] In step S30, once the heart sound collection module is activated to start working in step S20, the smart ring 100 starts timing and records how long the heart sound collection lasts; this "detection time" can be understood as the time counted from the start of the heart sound collection module; after the timing ends, the smart ring 100 decides what "first information" to send to the smart terminal according to the "detection time".

[0040] Case one representing insufficient time: if the timing shows that the duration of the heart sound collection does not exceed the preset threshold time, the content of the "first information" is to inform the user that "this detection is ended because the time is too short, and the data may be inaccurate or incomplete, please perform a longer detection again".

[0041] Case two representing sufficient time: if the timing shows that the duration of the heart sound collection exceeds the preset threshold time, the content of the "first information" will become the "physiological sign information" of the user. These information are the results obtained after the data collected by the heart sound collection module in a long enough time are processed and analyzed, such as heart rate, heart sound graph features, etc.

[0042] Through the above three steps, it is ensured that the heart sound detection is carried out under appropriate pressure conditions, and only when the collection time is long enough, the data is considered valid, so as to improve the accuracy and reliability of the detection.

[0043] In an embodiment of the present application, referring to Figure 6 , after the step of obtaining the pressure detection value of the pressure-sensitive component 30, the method further comprises: S21: When the pressure detection value is not within the preset pressure range, an end instruction is generated; S22: Control the heart sound collection module to exit the heart sound collection state according to the end instruction, and send the end instruction to the smart terminal. The end instruction is used by the smart terminal to generate pressure adjustment information.

[0044] In step S21, the smart ring 100 obtains the pressure detection value of the pressure-sensitive component 30 and uses the controller to determine whether the pressure detection value is within the preset pressure range. If the pressure applied to the housing 10 of the smart ring 100 is too high or too low, the controller's judgment result is "no", that is, the pressure value is either too high or too low, exceeding the preset pressure range, and step S21 is triggered. In this step, once an inappropriate pressure is detected, the controller inside the smart ring 100 immediately generates an end command. The purpose of this command is to inform the smart ring 100 itself and the smart terminal that the current heart sound collection conditions do not meet the requirements and the current collection process needs to be terminated.

[0045] In step S22, the controller of the smart ring 100 can generate and execute two synchronous or time-sharing actions according to the end instruction. Specifically, the first is to "control the heart sound collection module to exit the heart sound collection state", which means that the heart sound collection function previously activated in S20 will stop working and no longer collect heart sound signals to avoid collecting invalid or misleading data under erroneous conditions; at the same time or subsequently, the ring will send the "end instruction" to the smart terminal through a communication module such as Bluetooth. After receiving the "end instruction" with pressure problem information, the smart terminal will generate corresponding "pressure adjustment information" according to the instruction content; if the pressure is too high, the terminal will generate a prompt message, such as "Please reduce the pressure"; if the pressure is too low, the terminal will generate a prompt message, such as "Please increase the pressure to ensure that the ring is in good contact with the chest wall". This information will be displayed on the screen of the smart terminal to directly guide the user to perform the operation.

[0046] Through the above two steps, the feedback and correction mechanism of the smart ring 100 is formed, which is the direct consequence and response measure of the condition judgment in step S20.
