Description

Technical Field

[0001] This invention relates to the field of medical and health technology, and more specifically to a wearable multi-parameter monitoring wristwatch. Background Technology

[0002] Pulse diagnosis devices, traditional Chinese medicine pulse diagnosis, are large-scale integrated medical devices utilizing sensor technology, electronic technology, and intelligent computing technology. Although wearable versions exist, they only collect pulse data from one channel and lack automatic pressure application, control, and pulse detection technologies, making it difficult to meet people's healthcare needs. The human pulse signal contains rich physiological signals, which has greatly interested clinicians. Therefore, convenient, quick, and accurate pulse measurement has become crucial. With the development of science and technology, the accuracy of pulse measurement technology is constantly improving. Disadvantages include: large device size, inconvenience for patients, and the difficulty of miniaturizing wearable devices.

[0003] Cardiovascular function analyzer: Also known as a cardiovascular and cerebrovascular diagnostic instrument, it is a medical device that reflects cardiac function, vascular condition, blood status, and circulatory function. Based on the pulse pressure method principle, it consists of a single pulse sensor, etc. It is based on the pulse pressure method principle and the theoretical foundation established by the elastic cavity model of the human circulatory system. The model undergoes compartmental network analysis, and a series of calculation formulas are derived using linear correlation algorithms. These formulas, after nonlinear compensation and correction with clinical experience parameters, can obtain a set of 35 cardiovascular function parameters reflecting cardiac function, vascular status, and microcirculation function, as well as 64 expert-assisted diagnostic information items. Disadvantages include: the sensor sensitivity of existing equipment is not high, and detailed pulse wave signals, such as tidal waves, cannot be fully displayed; it cannot automatically increase or control pressure; and it cannot analyze myocardial ischemia, left ventricular failure, etc.

[0004] Oscillometric blood pressure measurement: Blood pressure is estimated based on the relationship between pulse wave amplitude and cuff pressure. The mean blood pressure corresponds to the maximum pulse wave amplitude, while systolic and diastolic blood pressure are determined by the proportion of the maximum pulse wave amplitude. The disadvantage is that the estimated systolic and diastolic blood pressure results are less accurate than those obtained with a Korotkoff sound mercury sphygmomanometer.

[0005] Artificial Korotkoff sound blood pressure measurement: also known as mercury sphygmomanometer measurement. It consists of a blood pressure cuff and a stethoscope. The cuff is wrapped around the upper arm and inflated. When the pressure inside the cuff exceeds the systolic artery pressure, blood flow is blocked. Then, the cuff is deflated. When the systolic pressure is higher than the pressure inside the cuff, part of the artery opens, and the blood jet creates eddies and conduction. This causes the blood vessels to vibrate, and the vibrations transmitted to the skin surface are called Korotkoff sounds. The first sound heard by the stethoscope on the artery is the systolic pressure; the complete disappearance of the sound is the diastolic pressure. Internationally, it is considered the gold standard for non-invasive blood pressure measurement. Disadvantages include: although widely used in the medical field, the measurement process using the Korotkoff sound method is complex and requires professional medical personnel for auscultation and recording; mercury leakage poses a significant hazard.

[0006] Electronic Korotkoff sounds are an electronic method for measuring blood pressure developed in the 1970s and 1980s. Its basic working principle is to use electronic technology to replicate the manual Korotkoff sound method. Specifically, an air pump is used to inflate and deflate the cuff, and an electronic microphone is used to listen to the pulse. The judgment method is almost identical to the manual method, except that a computer replaces human judgment. The advantages of this method are: (1) It reduces the workload of medical staff. (2) It has good consistency, eliminating differences between different medical personnel. The disadvantages are: (1) It is easily affected by external interference; other external sounds and vibrations can affect the accuracy. (2) The strength of the pulse in different individuals can also affect the measurement results.

[0007] The arterial tension method for measuring stroke-per-beat blood pressure, also known as the flattening tension method, applies external pressure to flatten the radial artery located near the bone. When the vessel is flattened by external pressure, the internal stress of the vessel wall changes. When the internal stress of the vessel equals the external force, the pressure on the surface is measured by a pressure sensor placed at the artery. The measured arterial pressure waveform at this point is the arterial blood pressure. The disadvantage is that the internal stress of the radial artery is affected by the thickness of muscle, fat, or other factors, resulting in a lower measured value of the external stress pressure than the actual value (stroke-per-beat blood pressure equals the pressure from the loss of muscle, fat, etc., plus the external stress). This affected pressure can only be estimated, affecting the accuracy of stroke-per-beat blood pressure.

[0008] The term "wind pulse" specifically refers to the pulse pattern unique to stroke patients. Its pulse theory is not entirely based on traditional pulse diagnosis concepts; it is a specific composite pulse pattern. The appearance of a right wind pulse indicates a lesion in the right brain tissue, clinically manifesting as left-sided limb dysfunction (left hemiplegia); a left wind pulse indicates a lesion in the left brain tissue, manifesting as right-sided limb dysfunction (right hemiplegia). Clinical practice has shown that the wind pulse can precede hemiplegia; in most hemiplegic patients, the wind pulse appears 3 months or even 2 years in advance, and the wind pulse can also disappear before recovery. Its role in early diagnosis of stroke and early prediction of rehabilitation is something that modern instruments cannot easily achieve. The disadvantages are: (1) Pulse diagnosis equipment is mostly found in large medical institutions, and its popularity is not high. (2) Pulse diagnosis equipment cannot automatically analyze the characteristic wind pulse pattern, making it inconvenient and slow.

[0009] Malignant tumors, as a major disease affecting human health, often present with subtle early symptoms. Therefore, early treatment and prognosis are crucial. Modern medicine is still refining its early diagnosis of highly malignant cancers such as lung and liver cancer, which presents an opportunity for exploration in traditional Chinese medicine (TCM) pulse diagnosis. While "malignant tumor" is a Western medical term, it has an overlapping relationship with TCM concepts like "accumulation" or "gathering." Pulse diagnosis instruments are a primary method for objective pulse analysis, and the extraction of pulse signal characteristics is a trend in studying the pulse patterns of patients with malignant tumors. However, TCM pulse diagnosis has limitations: it hasn't been integrated with Western medical equipment like CT scans and MRI, hasn't identified characteristic pulse patterns of malignant tumors, and lacks cross-validation with Western medical findings. Summary of the Invention

[0010] In view of this, the present invention provides a wearable multi-parameter monitoring wristwatch that integrates a traditional Chinese medicine pulse diagnosis instrument, a cardiovascular function tester, a modified Korotkoff blood pressure monitor, a modified non-invasive continuous pulse blood pressure monitor, and other multi-parameter monitoring devices, along with a cloud platform and remote diagnosis, into a single smartwatch. It analyzes: traditional Chinese medicine pulse patterns (including floating, middle, and deep pulses, 28 common pulse patterns, as well as special pulse patterns such as wind pulse, malignant tumor pulse, and arrhythmia pulse), cardiovascular function parameters (35 cardiovascular function parameters, 64 expert diagnostic information items, myocardial ischemia parameters, etc.), intermittent blood pressure, continuous beat blood pressure, and diseases such as cerebral infarction, cerebral hemorrhage, and malignant tumors. The data is transmitted via the cloud platform, and emergency calls and remote diagnosis are also provided.

[0011] To achieve the above objectives, the present invention adopts the following technical solution:

[0012] A wearable multi-parameter monitoring wristwatch includes a watch head, a pulse acquisition device, and a watch strap;

[0013] The watch head and the watch strap are connected;

[0014] The pulse acquisition device includes: a pulse pressure sensor and a liftable multi-layered airbag and an airbag receiving slot;

[0015] The watch strap includes a retractable outer strap and a wrist strap;

[0016] The retractable outer strip is pressed onto the wristband, and the sidewalls of the wristband are respectively provided with sliding grooves and sliding groove limiting protrusions;

[0017] The pulse pressure sensor includes a fluid cavity and a sensor array;

[0018] The sensor array is disposed inside the fluid cavity, and the bottom of the fluid cavity is connected to the liftable multi-layer airbag; the bottom of the liftable multi-layer airbag is fixed in the airbag receiving groove, and the airbag receiving groove is provided with a groove for fixing the radial head (this groove can accurately locate each pulse acquisition device at the cun, guan, and chi positions of the radial artery), and the airbag receiving groove is connected to the wristband.

[0019] A flexible circuit board is also disposed inside the fluid cavity, and the sensor array is disposed on the side of the flexible circuit board near the wrist; a pulse conditioning chip is integrated on the other side of the flexible circuit board.

[0020] The fluid cavity is also provided with a pressure membrane, which covers the fluid and the sensor array.

[0021] In this invention, the pulse pressure sensor is a highly sensitive pressure sensor, specifically including any one of the following: flexible piezoresistive, piezoelectric, capacitive, electromagnetic, or fiber optic sensors. Its sensitive area is determined based on the diameter of the radial artery, the size of the radial artery when it is fully closed, and the size of the fingertip pressure area at the cun, guan, and chi points in traditional Chinese medicine pulse diagnosis.

[0022] The fluid cavity can be a cuboid, cylinder, cube, or other cubic shape.

[0023] The flexible circuit board also integrates (chip) differential circuits, operational amplifier circuits, 50Hz notch filter circuits, filter circuits, or digital filters.

[0024] Preferably, the watch head includes a dial and a housing; the dial and the housing form a receiving space;

[0025] The containment space is equipped with a controller and a gas path control device;

[0026] The controller is connected to the air path control device; the air path control device is connected to the liftable multi-layer airbag.

[0027] Preferably, the sensor array includes several sensor units, and the areas of the several sensor units are all different.

[0028] Preferably, the sensor unit includes: a blood pressure measurement array unit: 8*14mm; a pulse measurement unit: 8*8mm; a radial artery closure 50% measurement unit: 4*4mm; and a pressure calibration unit: 1*1mm.

[0029] Preferably, the pulse acquisition device is provided in three parts: a cun pulse acquisition device, a guan pulse acquisition device, and a chi pulse acquisition device.

[0030] Preferably, the air circuit control device includes an air pressure sensor, a control air valve, and an air pump;

[0031] The air pressure sensor is connected to the air outlet of the liftable multi-layer airbag;

[0032] The air pump is connected to the air inlet of the liftable multi-layer airbag via the control air valve;

[0033] The pressure sensor, control valve, and air pump are all connected to the controller.

[0034] In this invention, the control valve can be a solenoid valve or a piezoelectric valve.

[0035] Preferably, the fluid in the fluid cavity is an insulating liquid or gas.

[0036] Preferably, the wristband is provided with a vent tube and an electrical wire through hole; the telescopic strap is provided with a buckle and a groove.

[0037] This invention employs a combination of second-order differential, period ratio, and wavelet transform for pulse wave feature point identification.

[0038] Unlike existing cardiovascular function analyzers, this invention collects pulse wave signals from the left cun position, which, according to traditional Chinese medicine theory, corresponds to the heart. Existing cardiovascular function analyzers collect pulse waves from the guan position, corresponding to the liver. Therefore, the location collected by this invention more accurately reflects cardiovascular function. In addition to analyzing various existing cardiovascular parameters based on the elastic cavity model of the human circulatory system, it also analyzes myocardial ischemia and left ventricular failure based on pulse wave characteristics. Specifically:

[0039] (1) Myocardial ischemia: The ratio of the height of the main wave peak of the right cun pulse wave to the height of the main wave peak of the left cun pulse wave is greater than 1.

[0040] (2) Left heart failure: The ratio of the height of the main peak of two adjacent pulse waves is greater than 1, and the ratio of the height of the main peak of the cross pulse wave is approximately 1.

[0041] Blood pressure monitoring using the aforementioned wearable multi-parameter monitoring wristwatch includes the following steps:

[0042] (1) Put on the watch, turn on the air pump, open the control air valve, and inflate the adjustable multi-layer airbag in the cun position through the air tube. The extension of the adjustable multi-layer airbag applies pressure to the pulse pressure sensor in the cun position. The pulse pressure sensor first contacts the skin on the radial artery. At this time, the pulse pressure acquisition system records the electrical signal, pressure value, and airbag pressure value of the skin in contact. Continue to inflate so that the pulse pressure sensor applies pressure to the radial artery. When the pulse pressure acquisition system collects the pulse wave and pressure value, record the height of the main wave peak of the first pulse wave, the pressure value, and the airbag pressure value at this time.

[0043] (2) Continue to inflate, the pulse pressure sensor applies pressure to the radial artery, and when the height of the main wave peak of the maximum pulse wave is collected, close the control air valve at the cun position. The multi-layer airbag can be raised and lowered to keep the air, ensuring that the pulse pressure sensor acquisition system can stably collect pulse signals. Record the height of the main wave peak of the second pulse wave, the pressure value, and the airbag pressure value at this time.

[0044] (3) Open the control valve of the joint to inflate the liftable multi-layer airbag of the joint. The airbag extends and applies pressure to the pulse pressure sensor. The pulse pressure sensor first contacts the skin of the joint and records the electrical signal, pressure value and airbag pressure value of the skin at this time.

[0045] (4) Continue to inflate the air so that the pulse pressure sensor applies pressure to the radial artery. When a pulse wave appears, record the peak height of the main wave of the pulse wave, the pressure value, and the airbag pressure value. Continue to inflate until the pulse wave at the cun position disappears. Turn off the air pump and control the air valve at the guan position to release air smoothly. When the peak height of the main wave of the first pulse wave, the pressure value, and the airbag pressure value appear at the cun position, the corresponding airbag pressure value at the guan position is reduced by the pressure value in contact with the skin. This pressure value is the systolic pressure.

[0046] (5) Continue to deflate steadily. The Guanbu pulse pressure acquisition system collects the peak height of the main wave of the maximum pulse wave, the pressure value, and the airbag pressure value. At this time, record the peak height of the main wave of the pulse wave, the pressure value, and the airbag pressure value collected by the Cunbu pulse pressure acquisition system. This pulse wave is the third pulse wave of the Cunbu.

[0047] (6) Continue to deflate steadily until the peak height of the second pulse wave appears at the cun position. At this time, the pulse wave peak height, pressure value, and airbag pressure value collected by the pressure sensor at the guan position are used. Then, the airbag pressure value is subtracted from the pressure value in contact with the skin. This pressure value is the diastolic pressure.

[0048] This invention differs from existing continuous stroke-per-second (CPS) blood pressure measurements. It is an improved CPS measurement method based on the aforementioned blood pressure measurements. The pulse pressure sensor acquisition system at the radial artery collects the stable, continuous maximum pulse wave, pressure value, and balloon pressure value. This is actually the pressure waveform collected when the stress within and outside the radial artery is equal, which represents the arterial blood pressure (the maximum value of the pressure waveform is systolic pressure, and the minimum value is diastolic pressure). Due to the influence of the thickness of the muscles, fat, and skin attached to the upper part of the radial artery, the pressure transmitted to the pulse pressure sensor is reduced. Therefore, the actual arterial blood pressure should include the affected pressure. The affected pressure portion is estimated using existing continuous stroke blood pressure data, such as height and weight. The intermittent blood pressure data presented in this invention actually includes this portion of blood pressure (i.e., systolic pressure is the peak height, pressure value, and cuff pressure of the stable first pulse wave at the cun position, corresponding to the cuff pressure value at the guan position (cuff pressure value minus the cuff pressure at skin contact); diastolic pressure is the peak height of the stable second pulse wave at the cun position, corresponding to the cuff pressure value and cuff pressure at the guan position. The systolic and diastolic pressures of subsequent continuous stroke blood pressure are then calibrated).

[0049] The portion of systolic blood pressure affected by muscles, fat, and skin is calculated as: intermittent systolic blood pressure minus the highest peak height, pressure, and cuff pressure of the continuous, stable, maximum pulse wave at the wrist. The portion of diastolic blood pressure affected by muscles, fat, and skin is calculated as: intermittent diastolic blood pressure minus the lowest peak height, pressure, and cuff pressure of the continuous, stable, maximum pulse wave at the wrist. Therefore, the continuous stroke-weighted systolic blood pressure is: the highest peak height, pressure, and cuff pressure of the continuous, stable, maximum pulse wave at the wrist, plus the portion of systolic blood pressure affected by muscles, fat, and skin. The continuous stroke-weighted diastolic blood pressure is: the lowest peak height, pressure, and cuff pressure of the continuous, stable, maximum pulse wave at the wrist, plus the portion of diastolic blood pressure affected by muscles, fat, and skin.

[0050] Unlike existing CT and MRI methods for diagnosing cerebrovascular diseases, this invention employs a three-position pulse pressure sensor system (cun, guan, chi) to collect data from both the left and right hands, automatically analyzing specific pulse patterns to predict cerebrovascular diseases early and prevent disability. Details are as follows:

[0051] Wear the device on your wrist, aligning the radial head with the groove on the airbag housing. Adjust the wristband connected to the airbag housing to ensure the liquid pulse pressure sensor is aligned with the radial artery at the cun, guan, and chi points. Press the telescopic outer strap onto the airbag housing, adjusting the tightness according to your wrist circumference. Fasten the strap and place the device flat on a table, palm up, at heart height. First, turn on the inflation pump, then turn on the cun bidirectional inflation control valve. Inflate the cun-position multi-layer airbag through the ventilation tube, causing it to extend and apply pressure to the cun-position liquid pulse pressure sensor. When the flexible pressure diaphragm of the liquid pulse pressure sensor senses the cun pulse on the radial artery, it transmits the pressure through the insulating liquid to the sensor array unit within the liquid pulse pressure sensor. The collected pulse pressure data is processed by the conditioning circuit and transmitted to... The pulse processing and calculation module transmits the processed pulse data, pressure values, and pressure values ​​of the multi-layer telescopic airbags detected by the air pressure sensor to the communication module, which then transmits them to the cloud platform. Simultaneously, the data is transmitted to the controller and display screen, recording the height, pressure, airbag pressure value, and pulse characteristics of the first pulse wave peak. The controller controls the inflation pump, and the bidirectional inflation control valve continues to inflate the multi-layer telescopic airbags at the cun position. Similarly, when the maximum pulse wave peak height is reached, the cun position micro-bidirectional inflation control valve is closed, stabilizing the air in the multi-layer telescopic airbags. This ensures stable pulse signal and pressure value acquisition by the liquid pulse pressure sensor. The air pressure sensor detects the pressure value of the multi-layer telescopic airbags, recording the height, pressure value, airbag pressure value, and optimal pulse characteristics of the second pulse wave peak. Similarly, the guan and chi pulse characteristics can be acquired separately, and the cun, guan, and chi pulse characteristics can be acquired simultaneously. By analyzing the pulse at the three points of the left and right hands—the cun, guan, and chi positions—one can discern cardiac function parameters, stroke, malignant tumors, and other diseases.

[0052] Extracting characteristic points from the pulse wave, in addition to identifying 28 basic pulse types and the superficial, middle, and deep pulses, it also identifies specific wind pulses. Key characteristic parameters include: the height of the main pulse wave peak h1, left cun h1 / right cun h1, left guan h1 / right guan h1, left chi h1 / right chi h1, left cun h1 / right guan h1 / right chi h1, right cun h1 / left guan h1 / left chi h1. <1> If left cun h1 / right cun h1>1, right cun h1 / left guan h1 / left chi h1 is approximately 1; if left guan h1 / right guan h1>1, right guan h1 / right chi h1 is approximately 1; the right guan and right chi pulses are deep, thready, and hesitant; the right cun, left guan, and left chi pulses are wiry. This suggests left cerebral hemorrhage and right-sided limb dysfunction. <2> Left Cun h1 / Right Cun h1>1, Right Cun h1 / Left Guan h1 / Left Chi h1 approximately 1, Left Guan h1 / Right Guan h1<1, Left Cun h1 / Right Guan h1 / Right Chi h1 approximately 1, the pulse strength of Right Cun, Left Guan, and Left Chi is weakened, deep, thin, and hesitant; turbid pulse appears in Left Cun, Right Guan, and Right Chi. This suggests right brain cerebral infarction and left-sided limb dysfunction.

[0053] See Figure 3 , different from the existing CT and nuclear magnetic resonance for tumor diagnosis. According to the detected pulse diagram, the present invention first determines each characteristic point b, c, d, e, f, g of the pulse wave, then determines the baseline and rhythm of the pulse condition, and then determines the height h1 of the main wave peak c point, the height h2 of the d point, the height h3 of the tidal wave e point, the height h4 of the notch of the dicrotic wave, and the height h5 of the dicrotic wave of the pulse wave. Automatically identify the characteristic pulse conditions of malignant tumors, specifically as follows:

[0054] (1) According to the determined pulse baseline, rhythm, and characteristic points, automatically identify that the overall pulse condition is unstable, one or more pulse conditions change, the rhythm is irregular, the waveform is intermittent, etc.;

[0055] (2) The ascending branch of the pulse wave is not smooth and has pauses, h2>h3>h1, the highest point forms an obtuse angle or a round and wide shape, h1 = h2 = h3, the highest point forms a flat top, h2<h3<h1 or h2<h3 = h1 or h2<h1<h3, and the highest point forms an "M" shape;

[0056] (3) h5<h4<h3<h2<h1, that is, the tidal wave, the notch of the dicrotic wave, and the dicrotic wave disappear and are replaced by serrated small waves. The number of serrated waves > 4, and they can also appear individually or simultaneously on the ascending branch of bc, mainly as the uneven pulse and variant pulse; (4) There is a single-hook pulse or a double-hook pulse at the f point of the notch of the dicrotic wave and the starting point b of the ascending branch, and they can appear simultaneously.

[0057] As can be seen from the above technical solutions, compared with the prior art, the present invention has the following beneficial effects:

[0058] (1) The monitoring watch provided by the present invention is different from the existing pulse acquisition terminals, with a small volume and multiple integrated functions;

[0059] (2) The present invention sets a sensor array in the fluid cavity, and sets the sensitive area according to the diameter and closing degree of the radial artery and the range of traditional Chinese medicine pulse-taking pressure. Utilizing the characteristics of fluid pressure transmission, the pressure generated by the radial artery pulsation is transmitted to each sensor unit through the fluid. Each sensor unit is set according to the above sensitive area, and according to the relationship between pressure, force area and pressure, the sensitivity of the pulse pressure sensor of the present invention is improved, and the complete information and pressure of the pulse can be collected more accurately;<>

[0060] (3) The present invention adopts a multi-array fluid pulse pressure sensor with high precision and high sensitivity, extracts the pulse signal by combining an analog amplification circuit, a filtering circuit, a temperature compensation chip and digital filtering, and together with the force area of the sensor sensitive area and the adaptability of the radial artery, improves the accuracy and sensitivity of the pulse signal. The morphological filtering method is used to remove the baseline drift and retain the integrity of the pulse data; <000>

[0061] (4) Unlike existing blood pressure measurement sites, this invention selects the Cun and Guan positions in traditional Chinese medicine pulse diagnosis. The purpose is that the muscles, skin and other tissues attached to the radial artery in these positions are thin, which has little impact on the pressure transmitted by the radial pulse, thus improving the accuracy of blood pressure measurement.

[0062] (5) Differentiating from existing CT and MRI tumor diagnoses. The characteristic pulse patterns of malignant tumors give priority to CT and MRI tumor diagnoses. This invention buys time for the early detection, prevention, and timely treatment of malignant tumors, prevents further deterioration, and reduces disability and mortality rates.

Continue to inflate so that the pulse pressure sensor applies pressure to the radial artery. When the pulse pressure acquisition system collects the pulse wave and pressure value, record the height of the main wave peak of the first pulse wave, the pressure value, and the airbag pressure value at this time.

[0099] (2) Continue to inflate, the pulse pressure sensor applies pressure to the radial artery, and when the height of the main wave peak of the maximum pulse wave is collected, close the control air valve at the cun position. The multi-layer airbag can be raised and lowered to keep the air, ensuring that the pulse pressure sensor acquisition system can stably collect pulse signals. Record the height of the main wave peak of the second pulse wave, the pressure value, and the airbag pressure value at this time.

[0100] (3) Open the control valve of the joint to inflate the liftable multi-layer airbag of the joint. The airbag extends and applies pressure to the pulse pressure sensor. The pulse pressure sensor first contacts the skin of the joint and records the electrical signal, pressure value and airbag pressure value of the skin at this time.

[0101] (4) Continue to inflate the air so that the pulse pressure sensor applies pressure to the radial artery. When a pulse wave appears, record the peak height of the main wave of the pulse wave, the pressure value, and the airbag pressure value. Continue to inflate until the pulse wave at the cun position disappears. Turn off the air pump and control the air valve at the guan position to release air smoothly. When the peak height of the main wave of the first pulse wave, the pressure value, and the airbag pressure value appear at the cun position, the corresponding airbag pressure value at the guan position is reduced by the pressure value in contact with the skin. This pressure value is the systolic pressure.

[0102] (5) Continue to deflate steadily. The Guanbu pulse pressure acquisition system collects the peak height of the main wave of the maximum pulse wave, the pressure value, and the airbag pressure value. At this time, record the peak height of the main wave of the pulse wave, the pressure value, and the airbag pressure value collected by the Cunbu pulse pressure acquisition system. This pulse wave is the third pulse wave of the Cunbu.

[0103] (6) Continue to deflate steadily until the peak height of the second pulse wave appears at the cun position. At this time, the pulse wave peak height, pressure value, and airbag pressure value collected by the pressure sensor at the guan position are used. Then, the airbag pressure value is subtracted from the pressure value in contact with the skin. This pressure value is the diastolic pressure.

[0104] Example 4

[0105] This invention measures continuous stroke-per-blood pressure: Based on the blood pressure measurement in Example 3, this invention improves upon continuous stroke-per-blood pressure measurement. The pulse pressure sensor acquisition system at the radial artery collects the stable, continuous maximum pulse wave, pressure value, and balloon pressure value. This is actually the pressure waveform collected when the stress within and outside the radial artery is equal, which is the arterial blood pressure (the maximum value of the pressure waveform is systolic pressure, and the minimum value is diastolic pressure). Due to the influence of the thickness of the attached muscles, fat, and skin structures in the upper part of the radial artery, the pressure transmitted to the pulse pressure sensor is reduced; therefore, the actual arterial blood pressure should include the affected pressure. The affected pressure portion is estimated using existing continuous stroke blood pressure data, such as height and weight. The intermittent blood pressure data presented in this invention actually includes this portion of blood pressure. (That is: systolic pressure is the peak height, pressure value, and cuff pressure value of the stable first pulse wave at the cun position, corresponding to the cuff pressure value at the guan position (cuff pressure value minus the cuff pressure value in contact with the skin); diastolic pressure is the peak height of the stable second pulse wave at the cun position, corresponding to the cuff pressure value and cuff pressure value at the guan position. The systolic and diastolic pressures of subsequent continuous stroke blood pressure are calibrated.)

[0106] The portion of systolic blood pressure affected by muscles, fat, and skin is calculated as: intermittent systolic blood pressure minus the highest peak height, pressure, and cuff pressure of the continuous, stable, maximum pulse wave at the wrist. The portion of diastolic blood pressure affected by muscles, fat, and skin is calculated as: intermittent diastolic blood pressure minus the lowest peak height, pressure, and cuff pressure of the continuous, stable, maximum pulse wave at the wrist. Therefore, the continuous stroke-weighted systolic blood pressure is: the highest peak height, pressure, and cuff pressure of the continuous, stable, maximum pulse wave at the wrist, plus the portion of systolic blood pressure affected by muscles, fat, and skin. The continuous stroke-weighted diastolic blood pressure is: the lowest peak height, pressure, and cuff pressure of the continuous, stable, maximum pulse wave at the wrist, plus the portion of diastolic blood pressure affected by muscles, fat, and skin.

[0108] The wearable multi-parameter monitoring wristwatch provided by this invention is used to diagnose cerebrovascular diseases. It employs a three-part pulse pressure sensor system (cun, guan, chi) to collect data from both the left and right hands, automatically analyzing specific pulse patterns to predict cerebrovascular diseases early and prevent disability. Details are as follows:

[0109] Wear the device on your wrist, aligning the radial head with the groove on the airbag housing. Adjust the wristband connected to the airbag housing to ensure the liquid pulse pressure sensor is aligned with the radial artery at the cun, guan, and chi points. Press the telescopic outer strap onto the airbag housing, adjusting the tightness according to your wrist circumference. Fasten the strap and place the device flat on a table, palm up, at heart height. First, turn on the inflation pump, then turn on the cun bidirectional inflation control valve. Inflate the cun-position multi-layer airbag through the ventilation tube, causing it to extend and apply pressure to the cun-position liquid pulse pressure sensor. When the flexible pressure diaphragm of the liquid pulse pressure sensor senses the cun pulse on the radial artery, it transmits the pressure through the insulating liquid to the sensor array unit within the liquid pulse pressure sensor. The collected pulse pressure data is processed by the conditioning circuit and transmitted to... The pulse processing and calculation module transmits the processed pulse data, pressure values, and pressure values ​​of the multi-layer telescopic airbags detected by the air pressure sensor to the communication module, which then transmits them to the cloud platform. Simultaneously, the data is transmitted to the controller and display screen, recording the height, pressure, airbag pressure value, and pulse characteristics of the first pulse wave peak. The controller controls the inflation pump, and the bidirectional inflation control valve continues to inflate the multi-layer telescopic airbags at the cun position. Similarly, when the maximum pulse wave peak height is reached, the cun position micro-bidirectional inflation control valve is closed, stabilizing the air in the multi-layer telescopic airbags. This ensures stable pulse signal and pressure value acquisition by the liquid pulse pressure sensor. The air pressure sensor detects the pressure value of the multi-layer telescopic airbags, recording the height, pressure value, airbag pressure value, and optimal pulse characteristics of the second pulse wave peak. Similarly, the guan and chi pulse characteristics can be acquired separately, and the cun, guan, and chi pulse characteristics can be acquired simultaneously. By analyzing the pulse at the three points of the left and right hands—the cun, guan, and chi positions—one can discern cardiac function parameters, stroke, malignant tumors, and other diseases.

[0110] (1) Extract the characteristic points of the pulse wave. In addition to identifying 28 basic pulse types and floating, middle, and deep pulses, identify the specific wind pulse. The main characteristic parameters are: the height of the main wave peak of the pulse wave h1, left cun h1 / right cun h1, left guan h1 / right guan h1, left chi h1 / right chi h1, left cun h1 / right guan h1 / right chi h1, right cun h1 / left guan h1 / left chi h1, <1> If left cun h1 / right cun h1>1, right cun h1 / left guan h1 / left chi h1 is approximately 1, left guan h1 / right guan h1>1, right guan h1 / right chi h1 is approximately 1, the right guan and right chi pulses are deep, thin, and hesitant; the right cun, left guan, and left chi pulses are wiry. This suggests left cerebral hemorrhage and right limb dysfunction.

[0111] (2) Left cun h1 / Right cun h1 > 1, Right cun h1 / Left guan h1 / Left chi h1 is approximately 1, Left guan h1 / Right guan h1 < 1, Left cun h1 / Right guan h1 / Right chi h1 is approximately 1. The pulse force of the right cun, left guan, and left chi is weakened, deep, thin, and unsmooth; turbid pulses appear in the left cun, right guan, and right chi. It indicates a cerebral infarction in the right brain and left limb dysfunction.

[0114] (1) According to the determined pulse condition baseline, rhythm, and characteristic points, automatically identify that the overall pulse condition is unstable, there is a change in one or more pulse conditions, the rhythm is irregular, the waveform is intermittent, etc.;

[0115] (2) The ascending branch of the pulse wave is not smooth and has pauses, h2 > h3 > h1, the highest point forms an obtuse angle or a round and wide shape, h1 = h2 = h3, the highest point forms a flat top, h2 < h3 < h1 or h2 < h3 = h1 or h2 < h1 < h3, and the highest point forms an "M" shape;
