[0002] Hypertension is a chronic disease characterized by persistently elevated arterial blood pressure. It is diagnosed by measuring systolic and / or diastolic blood pressure at rest. Its onset is closely related to factors such as genetics, lifestyle, age, and mental stress. Early hypertension usually has no obvious symptoms, but persistently elevated blood pressure will gradually damage target organs such as the heart, brain, kidneys, and blood vessels. It is an important risk factor for cardiovascular and cerebrovascular diseases and chronic kidney disease.

[0003] Commonly used blood pressure measuring devices on the market are usually large and not portable, requiring guidance from professional medical personnel and data interpretation. There are also some smart monitoring devices that look like watches, but these require users to wear special cuffs or watches, which can significantly limit their convenience and comfort in certain scenarios, making it difficult to meet users' needs for convenient and unobtrusive monitoring. Summary of the Invention

[0004] This application provides a blood pressure measurement system for smart glasses, which is small in size and comfortable and convenient to wear. It can measure blood pressure data in real time and display it intuitively, effectively improving the user experience.

[0005] To address the aforementioned technical problems, this application provides a blood pressure measurement system for use in smart glasses, the blood pressure measurement system comprising:

[0006] The monitoring unit includes a pressure transmitting element that fits in contact with the wearer's skin, and a pressure sensing element for monitoring pressure change data of the pressure transmitting element;

[0007] The driving unit includes a driving component and a pressure generating mechanism connected to the driving component. The driving component is used to drive the pressure generating mechanism to adjust the pressure of the pressure transmitting component in order to apply adjustable pressure to the blood vessels at the wearer's contact area.

[0008] The main control unit is used to receive pressure change data monitored by the pressure sensor and determine the wearer's blood pressure data based on the pressure change data.

[0009] As a further improvement of this application, the smart glasses include a frame and temples at both ends of the frame. The pressure transmitting element is located on the inner side of the two temples, and the pressure sensing element is located on the side of the pressure transmitting element away from the temples and is in contact with the wearer's skin.

[0010] As a further improvement of this application, the size of the pressure sensing element is smaller than the size of the pressure transmitting element, and the pressure sensing element is located at the center of the pressure transmitting element.

[0011] As a further improvement of this application, the ends of the two temples away from the frame are provided with straps so that the pressure sensing element and the pressure transmitting element are in contact with the wearer's skin.

[0012] As a further improvement of this application, the main control unit is used to determine the wearer's blood pressure data based on the pressure change data and in conjunction with the Korotkoff sound algorithm.

[0022] Compared with existing technologies, this application provides a blood pressure measurement system for smart glasses. The system integrates the blood pressure measurement system into the smart glasses, allowing the pressure transmission element to naturally conform to the wearer's skin during daily use, eliminating the need for additional cuffs or special equipment.

[0033] Hypertension is a chronic disease characterized by persistently elevated arterial blood pressure. It is diagnosed by measuring systolic and / or diastolic blood pressure at rest. Its onset is closely related to factors such as genetics, lifestyle, age, and mental stress. Early hypertension usually has no obvious symptoms, but persistently elevated blood pressure will gradually damage target organs such as the heart, brain, kidneys, and blood vessels. It is an important risk factor for cardiovascular and cerebrovascular diseases and chronic kidney disease.

[0034] Commonly used blood pressure measuring devices on the market are usually large and not portable, requiring guidance from professional medical personnel and data interpretation. There are also some smart monitoring devices that look like watches, but these require users to wear special cuffs or watches, which can significantly limit their convenience and comfort in certain scenarios, making it difficult to meet users' needs for convenient and unobtrusive monitoring.

[0035] For the above issues, please refer to Figures 1-2 This application provides a blood pressure measurement system for smart glasses, which is small in size and comfortable and convenient to wear. It can measure blood pressure data in real time and display it intuitively, effectively improving the user experience.

[0036] Optional, please refer to Figure 2The diagram below is a structural schematic of the smart glasses provided in the embodiments of this application. It can be observed that the smart glasses typically include a frame 1 and temples 2 located at both ends of the frame 1. This application applies a blood pressure measurement system to the smart glasses to monitor the wearer's blood pressure data in real time and conveniently.

[0037] As an optional implementation, the blood pressure measurement system provided in this application includes a monitoring unit, a driving unit, and a main control unit. The monitoring unit includes a pressure transmitting element 3 that fits in contact with the wearer's skin, and a pressure sensing element 4 for monitoring pressure change data of the pressure transmitting element 3. The driving unit includes a driving element (not shown in the figure) and a pressure generating mechanism 5 connected to the driving element. The driving element drives the pressure generating mechanism 5 to adjust the pressure of the pressure transmitting element 3, thereby applying adjustable pressure to the blood vessels at the wearer's contact point.

[0038] Further, please refer to Figure 1 This is a functional block diagram of the blood pressure measurement system provided in this application embodiment. The main control unit is used to receive pressure change data monitored by the pressure sensor 4 and determine the wearer's blood pressure data based on the pressure change data. This application sets the blood pressure measurement system in smart glasses, and drives the pressure generating mechanism 5 to apply adjustable pressure to the pressure transmission component 3 that is in contact with the wearer's skin through the driving component. The pressure transmission component 3 applies pressure to the blood vessels at the contact point of the wearer, thereby simulating the compression effect of traditional blood pressure measurement devices on blood vessels.

[0039] Meanwhile, the pressure sensor 4 monitors the pressure change data of the contact area in real time. Based on this pressure change data, the main control unit calculates the wearer's current blood pressure data using existing algorithms such as Korotkoff sound algorithm or oscillation algorithm.

[0040] This application integrates a blood pressure measurement system into smart glasses, allowing the pressure transmission device to naturally conform to the wearer's skin during daily use without the need for additional cuffs or special equipment. This solves the problem of limited convenience and comfort in specific scenarios. A drive unit drives the pressure transmission device to apply an adjustable pressure value to the blood vessels at the contact point. The main control unit can analyze and process the real-time pressure change data to obtain the wearer's current blood pressure data. Without the need for guidance or data interpretation from professional medical personnel, the wearer can intuitively obtain blood pressure data through smart glasses or a smart terminal, improving the convenience and accuracy of blood pressure monitoring.

[0041] Preferably, the pressure transmitting element 3 is located on the inner side of the two temples 2. When wearing smart glasses, the pressure transmitting element 3 fits tightly against the wearer's head directly, so there is no need to adjust the wearing position. The pressure transmitting element 3 located on the inner side of the temples 2 usually corresponds to the wearer's bilateral temporal region, where the superficial pulsation signal of blood vessels is obvious. Compared with the traditional monitoring position of the arm and wrist, the range of motion of this monitoring area is usually smaller, so it can achieve more stable acquisition of pressure data.

[0042] Furthermore, this application places the pressure sensor 4 on the side of the pressure transmission element 3 away from the temple 2 and in contact with the wearer's skin, so that the pressure sensor 4 directly contacts the wearer's skin, ensuring that the collected pressure change data is closer to the real data.

[0043] Of course, it is also feasible to place the pressure transmitting element 3 and the pressure sensing element 4 in other locations on the smart glasses, as long as it can be ensured that the monitoring unit fits in close contact with the wearer's skin and that adjustable pressure is applied to the blood vessels at the contact point through the pressure transmitting element 3. This application does not impose too many restrictions on the specific placement of the pressure transmitting element 3 and the pressure sensing element 4.

[0044] Furthermore, this application does not impose any restrictions on the thickness of the pressure transmission element 3, as long as it can apply adjustable pressure to the blood vessels at the bonding site through the pressure transmission element 3, as those skilled in the art should know.

[0045] As an optional implementation, this application sets the size of the pressure sensing element 4 to be smaller than the overall size of the pressure transmitting element 3. Preferably, the pressure sensing element 4 is set at the center of the pressure transmitting element 3 to prevent the pressure sensing element 4 from extending beyond the edge of the pressure transmitting element 3 and thus contacting the skin where no pressure is applied. In this case, the contact area between the pressure sensing element 4 and the wearer's skin is smaller than the contact area between the pressure transmitting element 3 and the wearer's skin, thereby collecting more accurate pressure change data.

[0046] Preferably, this application provides a strap 7 at the end of the two temples 2 away from the frame 1 to prevent the temples 2 from sliding when the wearer moves, so as to prevent the pressure transmitting element 3 from becoming loose at the point of contact with the wearer's skin. The strap 7 provides restraint to the end of the temples 2 of the smart glasses, ensuring that the pressure sensing element 4 and the pressure transmitting element 3 are in close contact with the wearer's skin.

[0047] In an optional embodiment, the main control unit provided in this application is used to determine the wearer's blood pressure data based on the collected pressure change data and the Korotkoff sound algorithm.

[0048] Specifically, the driving unit, through the pressure generating mechanism 5, causes the pressure transmitting element 3 to apply pressure to the contact area until the blood flow at the contact area is blocked. Then, the pressure is slowly released at a constant rate. The main control unit filters and analyzes the pressure change data to identify the first significant increase point in the pressure change data, i.e., the systolic pressure characteristic point, and the point where the pressure decreases and disappears, i.e., the diastolic pressure characteristic point. The wearer's systolic and diastolic pressures are determined based on the systolic and diastolic pressure characteristic points. Since the Korotkoff sound algorithm is a common algorithm in the field of blood pressure measurement, its implementation does not require a microphone, and its method of determining the wearer's systolic and diastolic pressures through the systolic and diastolic pressure characteristic points is well known to those skilled in the art. Therefore, this application will not elaborate further on it here.

[0049] For example, the wearer's blood pressure data can also be calculated using an oscillation algorithm. The main control unit filters the pressure change data, separates the dynamic oscillation signal corresponding to the heart rate cycle, obtains the pressure value corresponding to the maximum oscillation amplitude, i.e., the MAP (Mean Arterial Pressure) value, and then determines the wearer's blood pressure data by combining it with a preset oscillation amplitude attenuation ratio parameter.

[0050] It is understandable that the oscillation amplitude attenuation ratio parameter is an empirical parameter obtained by analyzing a large amount of clinical data for calibration. At the same time, the oscillation algorithm, i.e. the oscilloscope algorithm, is also a mature technology that is widely used in the current blood pressure measurement field. Therefore, the blood pressure measurement system provided in this application is a conventional application of the existing Korotkoff sound algorithm and oscilloscope algorithm, so it will not be elaborated on here.

[0051] In other words, the blood pressure data measured in this application includes at least systolic blood pressure data and / or diastolic blood pressure data. Once the blood pressure data is determined by the main control unit, the blood pressure data can not only be obtained intuitively through smart glasses, but also transmitted wirelessly to the wearer's smart terminal or directly to the cloud, so that the wearer can know the current blood pressure measurement status in a timely manner.

[0052] In an optional embodiment, the main control unit includes a main control chip 6 located inside the temple 2. The main control chip 6 is connected to the pressure sensor 4 and is used to receive pressure change data monitored by the pressure sensor 4. The main control chip 6 provided here can be in the form of common control chips such as MCU (Microcontroller Unit), FPGA (Field-Programmable Gate Array), and PLC (Programmable Logic Controller). This application does not further limit the specific configuration of the main control chip 6.

[0053] As an optional implementation, the aforementioned driving component can be configured as a drive motor, preferably as a micro drive motor. Since micro drive motors are small in size, typically in the millimeter range, they can be precisely installed in the temple 2 of the smart glasses as needed. Moreover, they typically operate with low noise and do not cause additional interference to the wearer, thus improving the user experience to a certain extent.

[0054] Furthermore, the pressure generating mechanism 5 can be set as a hydraulic pump. Hydraulic pumps typically use liquid as a medium and utilize the incompressibility of liquid to achieve linear pressure transmission. Compared with traditional pneumatic pumps, the pressure output fluctuation is smaller and the stability is higher.

[0055] As an optional implementation, this application preferably sets the pressure transmission element in the form of a liquid bladder. Since the liquid bladder is usually filled with medical-grade incompressible liquid, it can transmit the pressure generated by the pressure generating mechanism 5 to the wearer's contact area in a timely and even manner, avoiding pressure attenuation and fluctuation caused by traditional gas compression. At the same time, the liquid bladder is usually made of flexible material, so it fits the wearer's skin better, is convenient for daily wear and use, and has a high degree of comfort.

[0056] Furthermore, this application sets the pressure sensing element 4 in the form of a pressure sensor, which collects pressure change data in real time, ensuring the accuracy of pressure data measurement.

[0057] Of course, it is also feasible to set the above-mentioned driving component, pressure generating mechanism 5, pressure transmitting component 3 and pressure sensing component 4 in other forms, as long as the technical effects that the above-mentioned driving component, pressure generating mechanism 5, pressure transmitting component 3 and pressure sensing component 4 can achieve are achieved. This application does not impose any further restrictions on this.

[0058] It should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably. For system-type embodiments, since they are basically similar to method embodiments, the description is relatively simple; relevant parts can be referred to the descriptions in the method embodiments.

[0059] Furthermore, the functional units in the various embodiments of this application can be integrated into one processing unit, or each unit can exist physically separately, or two or more units can be integrated into one unit. The integrated units can be implemented in hardware or as software functional units. The above are merely implementation methods of the embodiments of this application and do not limit the patent scope of the embodiments of this application. Any equivalent structural or procedural transformations made based on the description and drawings of the embodiments of this application, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the embodiments of this application.

For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of the embodiments of this application, and these modifications and improvements are also considered to be within the protection scope of the embodiments of this application.
