[0002] At present, the cuff-type blood pressure monitor is a widely used blood pressure measurement device, which usually detects blood pressure based on the oscillometric method and the Korotkoff sound method. It is generally suitable for general blood pressure measurement. For conventional static blood pressure measurement, the cuff-type device can provide relatively accurate and stable readings.

[0003] Although cuff-type blood pressure monitors are widely used, there are obvious problems in some scenarios, such as:

[0004] Discomfort and accuracy: The device generates a certain amount of pressure when inflated, which may cause discomfort and disturb sleep, especially when used at night, especially when frequent measurements are required. It is difficult to achieve measurements without disturbing sleep. If sleep is affected, it will directly affect the accuracy of blood pressure measurement.

[0005] Intermittent measurement: Cuff-type blood pressure monitors can only measure during the inflation and deflation process, making continuous monitoring impossible. Cuff-type devices are not suitable for users who need 24-hour dynamic monitoring or monitoring during sleep.

[0006] Unable to reflect blood pressure fluctuations: Many diseases require attention to blood pressure fluctuations, but the intermittent measurement of a cuff-type blood pressure monitor is difficult to capture subtle changes.

[0007] Cuff-type blood pressure monitors have high accuracy and mature standards in static and intermittent measurements, but they have significant deficiencies in continuous monitoring, comfort, dynamic response, etc. These limitations make it difficult for cuff-type blood pressure monitors to meet the needs of people who need dynamic blood pressure monitoring or blood pressure monitoring during sleep.

[0024] The present application is further described in detail below through the accompanying drawings and embodiments. Through these descriptions, the characteristics and advantages of the present application will become clearer and more specific.

[0025] The word "exemplary" is used exclusively herein to mean "serving as an example, embodiment, or illustration." Any embodiment described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments. Although various aspects of the embodiments are shown in the drawings, the drawings are not necessarily drawn to scale unless otherwise noted.

[0026] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0027] The embodiment of the present application discloses a blood pressure monitoring device. The blood circulation system is composed of the heart and blood vessels. The heart is the power organ that promotes blood flow, and the blood vessels are the pipes for blood flow. Blood vessels are divided into three categories: arteries, capillaries, and veins. Arteries originate from the heart, and continue to branch, gradually becoming smaller in diameter and thicker in wall, and finally dividing into a large number of capillaries, which are distributed to various tissues and cells throughout the body. The capillaries then merge to form veins step by step. In the process of blood circulation, the blood ejected from the ventricles returns to the atria through the arteries, capillaries, and veins.

[0028] Blood pressure refers to the lateral pressure acting on the wall of a unit area of ​​blood vessels when blood flows in blood vessels. It is the driving force for blood to flow in blood vessels. Among them, blood vessels are divided into arteries, capillaries and veins. Correspondingly, blood pressure can be divided into arterial blood pressure, capillary blood pressure and venous blood pressure. The blood pressure mentioned in daily life refers to the blood pressure of the brachial artery in the artery. It should be understood that the blood pressure measured in this article is also the blood pressure of the brachial artery. Blood pressure further includes systolic pressure and diastolic pressure. Systolic pressure refers to when the heart contracts and pumps blood into the artery, the artery will expand to buffer the pressure, and the blood pressure at this time is the systolic pressure. Diastolic pressure refers to when the heart relaxes, the artery will contract so that the blood will flow back to the heart, and the blood pressure at this time is the diastolic pressure.

[0029] In view of the shortcomings of the existing technology, the present invention designs a blood pressure monitor that does not interfere with sleep and adopts new materials and technologies, taking into full consideration the wearing comfort and non-sensing experience of the user. Combining advanced technologies such as flexible electronic materials, optical and ultrasonic sensing technologies, micro-electromechanical system sensors, intelligent algorithms, and wireless data transmission, it can achieve accurate, non-invasive, and continuous blood pressure monitoring with minimal interference to the user's sleep. The device is not only suitable for daily blood pressure management, but also provides reliable health warning functions.

[0030] For the convenience of explanation, a first direction is defined, and the first direction is a direction in which the second wearing belt extends from one end connected to the wearing shell to the other end. In the accompanying drawings, the first direction is represented as an X direction.

[0031] A blood pressure monitoring device comprises a blood pressure monitoring component 1, a wearing component 2 and a controller 7. The blood pressure monitoring component 1 is used to monitor the blood pressure of a user in a first state, and comprises an optical sensor 11, a light source group 12, a micro-electromechanical system sensor 13, an ultrasonic generator 14 and an ultrasonic sensor 15.

[0032] The wearing component 2 is used to connect the blood pressure monitoring component 1 to the user's body, and includes a wearing shell 21, a first wearing belt 22, a second wearing belt 23 and a wearing tightness adjustment component 3.

[0033] The blood pressure monitoring component 1 is mounted on the wearing shell 21, one end of the first wearing belt 22 is connected to the wearing shell 21, and one end of the second wearing belt 23 is connected to the wearing shell 21. The ends of the first wearing belt 22 and the second wearing belt 23 away from the wearing shell 21 are connected by a wearing tension adjustment component 3, which is used to adjust the connection position of the first wearing belt 22 and the second wearing belt 23, and can adjust the wearing shell 21 to a first state, which is the state when the wearing shell 21 is worn on the arm with a set pressure.

[0034] The controller 7 is connected to the blood pressure monitoring component 1 and the wearing tightness adjustment component 3 by signals. The controller 7 can send an adjustment signal to the wearing tightness adjustment component 3. The controller 7 can send a monitoring signal to the blood pressure monitoring component 1 after sending the adjustment signal.

[0035] When receiving the adjustment signal, the wearing tightness adjustment component 3 adjusts the connection position between the first wearing belt 22 and the second wearing belt 23 to adjust the wearing shell 21 to the first state.

[0036] When receiving the monitoring signal, the blood pressure monitoring component 1 monitors the user's blood pressure in a first state.

[0037] Specifically, the blood pressure monitoring device includes three main parts: a blood pressure monitoring component 1, a wearing component 2, and a controller 7. The blood pressure monitoring component 1 is used to monitor the user's blood pressure in a first state. Compared with monitoring the user's blood pressure in other states, this solution sets a specific monitoring state to improve the accuracy of the monitored user's blood pressure.

[0038] The blood pressure monitoring component 1 uses at least two sensors to monitor the user's blood pressure. The two sensors can verify each other to improve the accuracy of the monitoring results. The monitoring results obtained by integrating multiple monitoring methods can reduce the monitoring errors caused by a single monitoring result due to its own monitoring principle, thereby further improving the accuracy of monitoring.

[0039] The wearing component 2 is used to install the blood pressure monitoring component 1 and the controller 7, and is used to wear the entire blood pressure monitoring device on the user's arm. The wearing component 2 can adjust its own state so that the wearing component 2 is in a first state, at which time the positions of the blood pressure monitoring component 1 and the controller 7 on the wearing component 2 remain relatively fixed, and the pressure between the blood pressure monitoring component 1 and the arm, which can also be understood as the pressure between the wearing component 2 and the arm, is at a set pressure.

[0040] The wearing component 2 and the blood pressure monitoring component 1 are both connected to the controller 7 by signal. The controller 7 sends signals to the wearing component 2 and the blood pressure monitoring component 1, so that the wearing component 2 can be adjusted to the first state, and the blood pressure monitoring component 1 can monitor the user's blood pressure in the first state.

[0041] The blood pressure monitoring component 1 is mounted on the wearing shell 21 , one end of the first wearing belt 22 is connected to the wearing shell 21 , and one end of the second wearing belt 23 is connected to the wearing shell 21 .

[0042] The ends of the first wearing strap 22 and the second wearing strap 23 away from the wearing shell 21 are connected by a wearing tension adjustment component 3, and the wearing tension adjustment component 3 is used to adjust the connection position of the first wearing strap 22 and the second wearing strap 23, and can adjust the wearing shell 21 to a first state, which is the state when the wearing shell 21 is worn on the arm with a set pressure.

[0043] One end of the first wearing strap 22 is connected to the wearing shell 21, and the other end is connected to the wearing tension adjustment component 3; one end of the second wearing strap 23 is connected to the wearing shell 21, and the other end is connected to the wearing tension adjustment component 3. The wearing tension adjustment component 3 adjusts the connection position of the first wearing strap 22 and the second wearing strap 23, and the wearing tension adjustment component 3 can move the connection position of the first wearing strap 22 and the second wearing strap 23, so that the inner diameter of the annular member formed by the first wearing strap 22, the second wearing strap 23 and the wearing shell 21 increases or decreases.

[0044] One end of the first wearing belt 22 is connected to the wearing shell 21, and the other end is connected to the end of the second wearing belt 23 away from the wearing shell 21 through the wearing tension adjustment component 3. The wearing tension adjustment component 3 can adjust the connection position of the first wearing belt 22 and the second wearing belt 23, thereby adjusting the inner diameter of the integral annular component formed by the first wearing belt 22, the second wearing belt 23 and the wearing shell 21. The annular component formed by the first wearing belt 22, the second wearing belt 23 and the wearing shell 21 can be worn and used by users with different arm thicknesses on the one hand, and can adjust the pressure between the arm when worn, so that the pressure when wearing the monitoring device is equal to the set pressure, so that the state of the wearing shell 21 is in the first state, and at this time, the blood pressure data of the user measured using the blood pressure monitoring component 1 is more accurate.

[0045] Reference Figure 1 The controller 7 is connected to the blood pressure monitoring component 1 and the wearing tightness adjustment component 3 by signals. The controller 7 can send an adjustment signal to the wearing tightness adjustment component 3. The controller 7 can send a monitoring signal to the blood pressure monitoring component 1 after sending the adjustment signal.

[0046] When receiving the adjustment signal, the wearing tightness adjustment component 3 adjusts the connection position between the first wearing belt 22 and the second wearing belt 23 to adjust the wearing shell 21 to the first state.

[0047] When receiving the monitoring signal, the blood pressure monitoring component 1 monitors the user's blood pressure in a first state.

[0048] The controller 7 can send an adjustment signal to the wearing tightness adjustment component 3. When receiving the adjustment signal, the wearing tightness adjustment component 3 adjusts the connection position of the first wearing strap 22 and the second wearing strap 23, and adjusts the wearing shell 21 to the first state; when the wearing shell 21 is adjusted to the first state, the controller 7 can send a monitoring signal to the blood pressure monitoring component 1. When receiving the monitoring signal, the blood pressure monitoring component 1 monitors the user's blood pressure in the first state, thereby obtaining accurate blood pressure data of the user.

[0049] Compared with directly using the blood pressure monitoring component 1 to measure the user's blood pressure, there are deviations in pressure and position between the blood pressure monitoring component 1 and the user. The pressure between the blood pressure monitoring component 1 and the user's arm may be too large or too small due to different wearing habits, which will cause a large deviation in the measurement results and low accuracy. The present application uses the blood pressure monitoring component 1 to perform blood pressure monitoring in the first state, thereby obtaining the user's blood pressure in the set state. The monitoring accuracy is high, and the monitoring process has little impact on the user, which is convenient for the user to wear.

[0050] In this embodiment, the controller 7 controls the wearing tension adjustment component 3 to maintain the wearing shell 21 in the first state. In another embodiment, only before the blood pressure monitoring component 1 is operated, the controller 7 controls the wearing tension adjustment component 3 to maintain the wearing shell 21 in the first state; in other cases, the tension on the wearing shell 21 is small, and the wearing component 2 is worn on the arm in a loose state relative to the first state.

[0051] Reference Figure 1 As an optional solution, the light source group 12 is used to emit at least two wavelengths of light to the user, and the optical sensor 11 receives the light reflected from the user. The optical sensor 11 and the light source group 12 are connected to the controller 7 signal, and the controller 7 is used to receive the signal of the optical sensor 11 to calculate the user's systolic and diastolic blood pressure.

[0052] The MEMS sensor 13 receives tiny pressure changes caused by tiny expansion and contraction of blood vessels in the user. The MEMS sensor 13 is connected to the controller 7 for signal. The controller 7 is used to receive the signal from the MEMS sensor 13 to calculate the systolic and diastolic blood pressure of the user.

[0053] The ultrasonic generator 14 is used to emit ultrasonic waves to the user, and the ultrasonic sensor 15 receives the ultrasonic waves reflected from the user. The ultrasonic generator 14 and the ultrasonic sensor 15 are connected to the controller 7 for signals. The controller 7 is used to receive the ultrasonic signal to calculate the user's blood flow velocity, and then calculate the systolic and diastolic blood pressures.

[0054] Specifically, the blood pressure monitoring device uses flexible electronic materials, which are thin and can fit the skin. It has good biocompatibility and will not have a significant impact on sleeping posture.

[0055] Using flexible conductive polymers or graphene as sensing materials, the sensor is designed as a film or patch. The film can be directly attached to the skin, such as the wrist or upper arm. Flexible materials are ultra-thin and lightweight, and are almost imperceptible when worn, making them particularly suitable for long-term wear during sleep at night. Materials such as graphene also have excellent conductivity and durability, making them suitable for high-precision biosignal monitoring.

[0056] Furthermore, the optical sensor 11 and the light source group 12 can measure the subcutaneous blood flow and pulse wave transmission time by embedding the micro optical sensor 11 in the monitoring device and using light sources of multiple wavelengths, such as infrared light and green light. The systolic and diastolic blood pressure of the user can be calculated by processing the data through algorithms.

[0057] Optical sensing technology is based on the light absorption characteristics of blood. Through the optical sensor 11, the pulse wave can be monitored in real time, thereby indirectly calculating the blood pressure. The optical sensor 11 has a compact structure and is suitable for integration in different locations such as bracelets, wristbands, headbands or mattresses. It does not require inflation, has no mechanical movement, is completely silent, and will not interfere with sleep.

[0058] Furthermore, the MEMS sensor 13 is capable of detecting very small pressure changes. The MEMS sensor 13 is integrated into the monitoring device to calculate the blood pressure by detecting the small expansion and contraction of the blood vessels. The pressure changes in the blood flow can be accurately detected and the data can be transmitted to the controller 7 for analysis.

[0059] The MEMS sensor 13 is small in size, low in power consumption, and fast in response. It can monitor and accurately calculate blood pressure in real time without causing physical interference.

[0060] Furthermore, the ultrasonic generator 14 and the ultrasonic sensor 15 emit ultrasonic waves through the ultrasonic generator 14, and the ultrasonic sensor 15 receives ultrasonic waves to measure the blood flow velocity in the blood vessels, thereby calculating the blood pressure. The ultrasonic generator 14 and the ultrasonic sensor 15 are designed as a small patch installed on the monitoring device, and use ultrasonic waves to detect the transmission speed of the pulse wave and the change in the inner diameter of the blood vessel to calculate the blood pressure.

[0061] The ultrasonic sensor 15 uses ultrasound to measure blood pressure, which is more non-invasive and does not interfere with the user's activities compared to traditional cuff-type blood pressure monitors. Ultrasonic technology has high accuracy and has almost no effect on sleep. By optimizing the design of the sensor, blood pressure changes can be monitored in real time and continuously.

[0062] By combining optical and MEMS sensors 13 and ultrasonic monitoring, multiple sensor fusion technologies are used to ensure data accuracy. Deep learning algorithms can further allow the device to adapt to the individual differences of different users, ensuring the most accurate blood pressure monitoring results even during sleep.

[0063] The blood pressure monitoring component 1 measures the user's blood pressure by using multiple sensors, relatively calibrates the different blood pressures measured, and outputs the user's monitored blood pressure results after comprehensive comparison, thereby improving the accuracy and reliability of the monitored blood pressure results.

[0064] Reference Figure 1 As an optional solution, the blood pressure monitoring device also includes a signal transmission component 5, which is connected to the controller 7 by signal, and the signal transmission component 5 includes at least one of a Bluetooth module, a Wi-Fi module, a 4G module or a 5G module.

[0065] Specifically, the signal transmission component 5 includes a Bluetooth module, a Wi-Fi module, a 4G module and a 5G module.

[0066] The monitoring device transmits data to the mobile phone application or cloud platform in real time via Bluetooth, Wi-Fi or other means. Users can check the blood pressure data at night in the morning and get corresponding health advice. They can also use the cloud analysis platform to conduct in-depth analysis of blood pressure trends using big data.

[0067] Wireless data transmission reduces device storage pressure, while cloud analysis can provide more accurate health warnings and trend analysis.

[0068] Reference Figure 1 As an optional solution, the blood pressure monitoring device also includes a nano coating, which is coated on the outside of the wearable component 2.

[0069] Specifically, nanoparticles or nanostructures are deposited on the surface of the wearable component 2 through a specific process, so as to form a coating layer with special properties on the surface of the wearable component 2, thereby forming a wearable component 2 with a nano coating on the surface.

[0070] To ensure the long-term wearing comfort and hygiene of the device, the use of nano-coating can enhance the device's waterproof, sweat-proof, dust-proof performance, and has antibacterial functions.

[0071] A nano-antibacterial coating is applied to the surface of the device to prevent bacteria from growing at the point where the skin contacts the device. At the same time, the nano-coating can also provide waterproof and sweat-proof functions to ensure that the sensor can maintain stable operation in various environments.

[0072] Nano-coating improves the durability and hygiene of the device, especially for blood pressure monitoring devices that are worn for long periods of time, reducing the possibility of skin irritation.

[0073] Reference Figure 1 As an optional solution, the wearing shell 21 includes a plurality of substrates arranged in a single row, two adjacent substrates are hingedly connected, and the blood pressure monitoring component 1 is arranged on the substrate.

[0074] Specifically, the substrate is a rectangular strip made of flexible material. When the monitoring device is worn on the arm, the length direction of the substrate is along the arm span direction, and the width direction of the substrate is along the circumference direction of the arm. There are multiple substrates, and the multiple substrates are connected in sequence for the first time to form the entire wearing shell 21. The provision of multiple substrates makes the wearing shell 21 more flexible and improves the wearing comfort. The substrate is not shown in the accompanying drawings, and the hinged connection between two adjacent substrates is connected using the existing technology, which will not be described in detail here.

[0075] Reference Figure 1 As an optional solution, the blood pressure monitoring device also includes a display module 6 arranged on the wearing shell 21, and the display module 6 is used to display signals including time information, blood pressure change information and real-time blood pressure information.

[0076] Specifically, the display module 6 is a display screen, and the display module 6 is connected to the controller 7 by signal. The display module 6 can display the current time information, the blood pressure change curve within a period of time, and the current systolic and diastolic blood pressure of the user.

[0077] The entire monitoring device is wrapped with medical-grade flexible polymer material to ensure that the monitoring device can fit the skin comfortably. The LED light source and light sensor module are arranged on the inside of the monitoring device, in close contact with the skin, to capture the precise signal generated by the change in blood vessel volume caused by the heart beat. The micro-electromechanical system sensor 13 is integrated in the monitoring device to sense the tiny fluctuations of the pulse wave. With a battery, a power supply module and a wireless charging module, it can support convenient wireless charging, avoid wear and tear on the charging interface, and reduce the inconvenience caused by wired charging. Use low-power batteries to ensure that the battery can continue to work all night and maintain low power consumption.

[0078] It can collect sensor data and perform preliminary processing, and transmit data efficiently and with low latency. It supports low-power Bluetooth transmission and transmits real-time data to the user's mobile phone application. Users can view real-time blood pressure data, historical trends, and health reports through the corresponding mobile phone application. The corresponding mobile phone application can provide intelligent data analysis and remind users when blood pressure is abnormal to ensure safety.

[0079] When in use, the blood pressure monitoring component 1 is started, and the device automatically starts and begins to collect signals and pulse wave transmission time data generated by changes in blood vessel volume caused by heart beats. The controller 7 collects data in real time and uses intelligent algorithms to remove interference and perform calibration. The data is transmitted to the mobile phone application via Bluetooth, and the user can check the changes in blood pressure at night at any time. When abnormal blood pressure is detected, the mobile phone application will remind the user or provide corresponding health advice.

[0080] Reference Figure 2 As an optional solution, the wearing tightness adjustment component 3 includes a connecting shell 31, a first adjusting roller wheel 32, a second adjusting roller wheel 33, a first motor 34, and a second motor 35.

[0081] the first adjusting roller wheel 32 is assembled in the connecting shell 31 and rotates around its own axis, and the second adjusting roller wheel 33 is assembled in the connecting shell 31 and rotates around its own axis, and the axis of the second adjusting roller wheel 33 is parallel to the axis of the first adjusting roller wheel 32.

[0082] The first motor 34 drives the first adjusting roller wheel 32 to rotate, and the second motor 35 drives the second adjusting roller wheel 33 to rotate; the first motor 34 and the second motor 35 are respectively connected to the controller 7 by signal, and the first motor 34 and the second motor 35 can receive the forward signal, the reverse signal and the balance signal sent by the controller 7. The first motor 34 and the second motor 35 rotate forward when receiving the forward signal, reverse when receiving the reverse signal, and lock when receiving the balance signal.

[0083] One end of the second wearing band 23 away from the wearing shell 21 is located between the first adjusting roller wheel 32 and the second adjusting roller wheel 33 , and two surfaces in the thickness direction of the second wearing band 23 are pressed against the first adjusting roller wheel 32 and the second adjusting roller wheel 33 respectively in a one-to-one correspondence.

[0084] Specifically, the connecting shell 31 is fixedly connected to the first wearing belt 22, and the connection method is determined according to needs. A buckle can be used for pressing connection, or a glue bonding connection can be used.

[0085] The output shaft of the first motor 34 is coaxially fixed with the first regulating roller 32, and the first motor 34 drives the first regulating roller 32 to rotate around its own axis when it is started. The output shaft of the second motor 35 is coaxially fixed with the second regulating roller 33, and the second motor 35 drives the second regulating roller 33 to rotate around its own axis when it is started.

[0086] The first adjusting roller wheel 32, the second adjusting roller wheel 33, the first motor 34, and the second motor 35 are all installed in the connecting shell 31, and the first adjusting roller wheel 32 is installed in the connecting shell 31 to rotate around its own axis, the axis of the second adjusting roller wheel 33 is parallel to the axis of the first adjusting roller wheel 32, and the second adjusting roller wheel 33 is installed in the connecting shell 31 to rotate around its own axis.

[0087] The first motor 34 and the second motor 35 are both connected to the controller 7 by signals. The first motor 34 can receive the forward signal, reverse signal and balance signal sent by the controller 7. The first motor 34 rotates forward when receiving the forward signal, reverses when receiving the reverse signal, and locks when receiving the balance signal. The second motor 35 can receive the forward signal, reverse signal and balance signal sent by the controller 7. The second motor 35 rotates forward when receiving the forward signal, reverses when receiving the reverse signal, and locks when receiving the balance signal. Locking means that the first motor 34 and the second motor 35 stop rotating and will not rotate under a certain external force. Under the external force, the first adjusting roller wheel 32 and the second adjusting roller wheel 33 also remain stable and will not rotate. When the external force exceeds the external force, the first adjusting roller wheel 32 will drive the first motor 34 to rotate, and the second adjusting roller wheel 33 will drive the second motor 35 to rotate.

[0088] One end of the second wearing band 23 away from the wearing shell 21 is located between the first adjusting roller wheel 32 and the second adjusting roller wheel 33 , and two opposite surfaces of the second wearing band 23 are pressed against the first adjusting roller wheel 32 and the second adjusting roller wheel 33 in a one-to-one correspondence.

[0089] The gap between the first adjusting roller wheel 32 and the second adjusting roller wheel 33 is always smaller than the thickness of the second wearing belt 23. When the second wearing belt 23 is located between the first adjusting roller wheel 32 and the second adjusting roller wheel 33, the first adjusting roller wheel 32 and the second adjusting roller wheel 33 always maintain an extruded state with the second wearing belt 23.

[0090] When the controller 7 sends a forward pull signal, the first motor 34 drives the first adjusting roller 32 to rotate clockwise, and the second motor 35 drives the second adjusting roller 33 to rotate counterclockwise. When the first adjusting roller 32 rotates clockwise and the second adjusting roller 33 rotates counterclockwise, the first adjusting roller 32 and the second adjusting roller 33 drive the second wearing belt 23 to move, and move the second wearing belt 23 in a direction away from the wearing shell 21. The inner diameter of the integral annular component formed by the first wearing belt 22, the second wearing belt 23 and the wearing shell 21 is reduced, and the wearing shell 21 is further attached to the surface of the user's arm. When the inner diameter of the integral annular component formed by the first wearing belt 22, the second wearing belt 23 and the wearing shell 21 is reduced to a set size, the wearing shell 21 is in the first state.

[0091] When the controller 7 sends a backward signal, the first motor 34 reverses to drive the first adjusting roller 32 to rotate counterclockwise, and the second motor 35 forwardly drives the second adjusting roller 33 to rotate clockwise. When the first adjusting roller 32 rotates counterclockwise and the second adjusting roller 33 rotates clockwise, the first adjusting roller 32 and the second adjusting roller 33 drive the second wearing belt 23 to move, and move the second wearing belt 23 in the direction toward the wearing shell 21. The inner diameter of the integral annular component formed by the first wearing belt 22, the second wearing belt 23 and the wearing shell 21 increases, and the wearing shell 21 is further relaxed on the surface of the user's arm.

[0092] Furthermore, a rubber layer is provided on the surface of the first adjusting roller wheel 32 and the second adjusting roller wheel 33 to increase the friction between the first adjusting roller wheel 32 and the second adjusting roller wheel 33 and the second wearing belt 23 .

[0093] Reference Figure 2 As an optional solution, the wearing tightness adjustment component 3 further includes an elastic member 36 and a first bracket 37. The first bracket 37 is hinged on the connecting shell 31, and the first adjusting roller wheel 32 is assembled on the first bracket 37 so as to rotate around its own axis; one end of the elastic member 36 is connected to the connecting shell 31, and the other end is connected to the first bracket 37, and an elastic force is applied to the first bracket 37 to move the first adjusting roller wheel 32 toward the second adjusting roller wheel 33.

[0094] Specifically, the first bracket 37 is hinged on the connecting shell 31, and the hinge axis of the first bracket 37 is parallel to the axis of the first adjusting roller wheel 32. The first bracket 37 is similar to a Y-shaped bracket, and one end of the first bracket 37 is hinged on the connecting shell 31, and the other two ends are provided with parallel circular holes, and the two ends of the first adjusting roller wheel 32 pass through and extend out of the circular holes, so that the first adjusting roller wheel 32 is assembled on the first bracket 37 for rotation. The first motor 34 is installed on the outside of the first bracket 37, and the output shaft of the first motor 34 is coaxially fixed with the first adjusting roller wheel 32. When the first bracket 37 rotates, the first motor 34 and the first adjusting roller wheel 32 rotate synchronously. When the first motor 34 is started, it drives the first adjusting roller wheel 32 to rotate around its own axis.

[0095] The elastic member 36 is a spring, one end of which is connected to the connection shell 31, and the other end of which is connected to the first bracket 37. In this embodiment, the elastic member 36 is a tension spring. In another embodiment, the elastic member 36 is a compression spring. The elastic member 36 applies a pulling force to the first bracket 37, so that the first bracket 37 in the inclined state has a tendency to rotate and increase the inclined state to the vertical state.

[0096] The elastic force applied by the elastic member 36 to the first bracket 37 causes the first adjusting roller wheel 32 on the first bracket 37 to press against the second wearing belt 23, pressing the second wearing belt 23 against the second adjusting roller wheel 33, thereby increasing the pressing force among the first adjusting roller wheel 32, the second wearing belt 23 and the second adjusting roller wheel 33.

[0097] When the first adjusting roller wheel 32 and the second adjusting roller wheel 33 rotate, the first adjusting roller wheel 32 and the second adjusting roller wheel 33 can drive the second wearing belt 23 to move. When the first adjusting roller wheel 32 and the second adjusting roller wheel 33 stop rotating, the second wearing belt 23 can be pressed and fixed between the first adjusting roller wheel 32 and the second adjusting roller wheel 33 and remain fixed.

[0098] Regarding how to determine whether the wearing shell 21 is in the first state, in this embodiment, the following structure is used to determine whether the wearing shell 21 is in the first state. In another embodiment, one end of the second wearing belt 23 used to connect with the wearing shell 21 is connected to a pressure sensor, the pressure sensor is fixed in the wearing shell 21, and the pressure sensor is connected to the controller 7 by signal. When the pressure sensor detects a set pressure, the wearing shell 21 is in the first state.

[0099] Reference Figure 3 As an optional solution, the blood pressure monitoring device also includes a starting member 41, an elastic sheet 42 and a position sensor 43.

[0100] The starting member 41 is slidably installed in the wearing shell 21 along the direction of the watch strap. The starting member 41 is fixedly connected to the second wearing strap 23. The starting member 41 can slide in a set area under the pull of the second wearing strap 23; the elastic sheet 42 is arranged between the starting member 41 and the wearing shell 21, and applies a force to the starting member 41 away from the second wearing strap 23.

[0101] The position sensor 43 is used to detect the position of the starting member 41, and the detected positions include an initial position 431, a first area 432, a balance position 433, and a second area 434 which are sequentially arranged along the direction of the starting member 41 toward the second wearing band 23; when the starting member 41 is located at the balance position 433, the position sensor 43 sends a first signal to the controller 7; when the starting member 41 is located at the initial position 431, the position sensor 43 sends a second signal to the controller 7.

[0102] When the starting member 41 is located in the first area 432 , the position sensor 43 sends a third signal to the controller 7 ; when the starting member 41 is located in the second area 434 , the position sensor 43 sends a fourth signal to the controller 7 .

[0103] The controller 7 sends a balance signal when receiving the first signal or the second signal, sends a forward pull signal when receiving the third signal, and sends a backward move signal when receiving the fourth signal.

[0104] Specifically, a guide rail 44 is installed in the wearing shell 21, and the guide rail 44 is arranged along the first direction. The starting member 41 is slidably installed on the guide rail 44 and can slide back and forth along the first direction.

[0105] One end of the second wearing belt 23 for connecting with the wearing shell 21 is connected to the starter 41. The starter 41 moves from the initial position 431, the first area 432, the equilibrium position 433, and the second area 434 in sequence along the first direction.

[0106] A position sensor 43 is provided in the wearing shell 21. The position sensor 43 determines the position of the starter 41. When the position sensor 43 detects that the starter 41 is located in the first area 432, the position sensor 43 sends a third signal to the controller 7. When the controller 7 receives the third signal, it sends a forward pull signal. When the first motor 34 and the second motor 35 receive the forward pull signal, the first motor 34 drives the first adjusting roller wheel 32 clockwise and the second motor 35 drives the second adjusting roller wheel 33 counterclockwise to reduce the inner diameter of the overall annular component formed by the first wearing strap 22, the second wearing strap 23 and the wearing shell 21.

[0107] When the position sensor 43 detects that the starter 41 is located in the second area 434, the position sensor 43 sends a fourth signal to the controller 7. The controller 7 sends a backward signal when receiving the third signal. When the first motor 34 and the second motor 35 receive the backward signal, the first motor 34 drives the first adjusting roller wheel 32 counterclockwise and the second motor 35 drives the second adjusting roller wheel 33 clockwise, thereby increasing the inner diameter of the overall annular component formed by the first wearing strap 22, the second wearing strap 23 and the wearing shell 21.

[0108] When the position sensor 43 detects that the starter 41 is at the balance position 433, the position sensor 43 sends a first signal to the controller 7. The controller 7 sends a balance signal when receiving the first signal. When the first motor 34 and the second motor 35 receive the balance signal, the first motor 34 locks the first adjusting roller wheel 32 and the second motor 35 locks the second roller. The first adjusting roller wheel 32 and the second adjusting roller wheel 33 press the second wearing strap 23 to maintain a stable connection between the second wearing strap 23 and the wearing tightness adjustment component 3.

[0109] The elastic sheet 42 is a W-shaped elastic sheet. An avoidance hole 421 is provided on the elastic sheet 42 . The second wearing belt 23 passes through the elastic sheet 42 through the avoidance hole 421 .

[0110] When the controller 7 sends a forward pull signal, the first motor 34 drives the first adjusting roller 32 to rotate clockwise, and the second motor 35 drives the second adjusting roller 33 to rotate counterclockwise. When the controller 7 sends a backward move signal, the first motor 34 drives the first adjusting roller 32 to rotate counterclockwise in reverse, and the second motor 35 drives the second adjusting roller 33 to rotate clockwise in forward rotation.

[0111] Reference Figure 2 As an optional solution, the connecting shell 31 is detachably fixedly connected to the first wearing belt 22.

[0112] The second wearing band 23 includes a transition section 231 . The transition section 231 is located at one end of the second wearing band 23 away from the wearing shell 21 . The thickness of the transition section 231 gradually decreases in a direction away from the wearing shell 21 .

[0113] Specifically, the width of the transition section 231 gradually decreases in a direction away from the wearing shell 21. The provision of the transition section 231 facilitates the end of the second wearing belt 23 to be inserted between the first adjusting roller wheel 32 and the second adjusting roller wheel 33.
