Description
Technical Field
The invention relates to the technical field of medical health, in particular to a wearable multi-parameter monitoring wristwatch.
Background
Pulse condition instrument: the pulse taking device is large-scale medical equipment integrating the traditional Chinese medicine pulse taking technology, the electronic technology, the intelligent operation technology and the like, and is difficult to meet the medical health requirements of people due to the fact that only one pulse condition is acquired, but not automatic pressurization, pressure control, pulse searching and other technologies are adopted. The human body pulse signals contain rich physiological signals, which also arouses great interest of clinicians, so that the convenient, quick and accurate measurement of the pulse signals becomes key, and along with the development of scientific technology, the pulse measurement technology has higher and higher measurement accuracy of the pulse. The disadvantages are: the equipment is large in size, inconvenient for patients to use and difficult in wearable miniaturization technology.
Cardiovascular function analyzer: the diagnosis instrument for cardiac and cerebral vascular diseases is one kind of medical instrument reflecting cardiac function, vascular condition, blood state and circulation function, and consists of single pulse sensor, etc. based on pulse pressure principle. Based on the pulse pressure method principle, according to the theoretical basis established by the elastic cavity model of the human circulatory system, the model is subjected to compartment network analysis, a series of calculation formulas are deduced by using a linear correlation algorithm, and the formulas are subjected to nonlinear compensation and clinical experience parameter correction, so that 35 cardiovascular function parameters and 64 expert auxiliary diagnosis information of the projected cardiac function, vascular state and microcirculation function can be obtained. The disadvantages are: the sensitivity of the sensor of the existing equipment is not high, and detailed signals of pulse waves, such as tide waves, can not be completely displayed; the automatic pressurization, pressure control and the like cannot be performed; myocardial ischemia, left heart failure, etc. cannot be analyzed.
Oscillometric blood pressure measurement: the blood pressure is estimated from the relationship between the pulse wave amplitude and the cuff pressure. Corresponding to the maximum pulse wave amplitude is the average pressure, and the systolic and diastolic pressures are determined by the pulse wave maximum amplitude ratio, respectively. The disadvantages are: the estimated systolic pressure and diastolic pressure have less accurate measurement results than the Korotkoff sound mercury sphygmomanometer.
Measuring blood pressure by artificial Korotkoff sounds: also known as mercury sphygmomanometer measurements. The cuff is wound on the upper arm, the cuff is inflated, when the pressure in the cuff exceeds the arterial systolic pressure, blood flow is blocked, then the cuff is deflated, when the systolic pressure is higher than the pressure in the cuff, part of arteries are opened, blood flow is sprayed to form vortex and flow transmission, the blood flow vibrates and is transmitted to the body surface to be the Korotkoff sound, the stethoscope on the arteries hears the first sound, namely the systolic pressure, and the sound completely disappears, namely the diastolic pressure. Internationally referred to as the gold standard for noninvasive blood pressure measurement. The disadvantages are: mercury sphygmomanometers using the koff sound method are widely used by the medical community, but the measurement process is complex, and the auscultation record is required by professional medical staff; the risk of mercury leakage is great.
Electronic Korotkoff sounds were developed in the 70-80 s as a method for electronically measuring blood pressure. The basic working principle is that an artificial Korotkoff sound method is completed by an electronic technology. That is, the cuff is inflated and deflated by an air pump. Listening to the pulse sound is done with an electronic sound pick-up. The judgment method is almost the same as that of manual work, except that a computer is used instead of the judgment of a person. The method has the advantages that: and (1) the labor intensity of medical staff is reduced. (2) The consistency is better, and no difference exists between different medical staff. The disadvantages are: (1) Is susceptible to external interference, i.e. other external acoustic vibrations can affect accuracy. (2) The pulse intensity of different people also has a certain influence on the measurement result.
Arterial tension method measures continuous blood pressure per beat: also called as a flat tension method, external pressure is applied to make radial artery near bone become flat, when the blood vessel is flattened by the external pressure, the internal stress of the vessel wall changes, when the internal stress of the blood vessel is equal to the external force, the pressure on the surface is measured by a pressure sensor arranged at the artery position, and the measured beat-by-beat arterial pressure waveform is arterial blood pressure. The disadvantages are: the radial internal stress is affected by the thickness of the muscle, fat, etc. or otherwise, and the external stress pressure measurement is smaller than the actual one (the pressure of each beat is equal to the pressure of the part of the muscle, fat, etc. which is lost plus the external stress), and the affected part of the pressure can only be estimated, which affects the accuracy of the pressure of each beat.
The wind pulse refers to the special pulse condition of the patients suffering from cerebral apoplexy. The pulse condition is not the traditional pulse concept, and is a special compound pulse condition. When right wind pulse indicates right brain tissue lesion, left limb dysfunction (left hemiplegia) clinically occurs; the left wind pulse suggests left brain tissue lesions, right limb dysfunction (right hemiplegia). Clinical practice proves that the wind pulse can precede hemiplegia, and most hemiplegia patients can lead the wind pulse to appear 3 months earlier and even 2 years earlier, and the wind pulse can disappear before healing. He has advanced diagnosis and advanced prognosis of cerebral apoplexy, which is not suitable for modern instruments. The disadvantages are: (1) Pulse-taking equipment is mostly used in large medical institutions, and the popularization rate is not high. (2) The pulse diagnosis equipment can not automatically analyze the characteristic wind pulse condition, which is inconvenient and quick.
The malignant tumor is a major disease of human health, early symptoms are not obvious, so that early treatment and prognosis of the tumor are very important, modern medicine is perfect for some cancer species with higher malignant degree such as lung cancer, liver cancer and the like, the early diagnosis is just a place for excavating and exploring pulse diagnosis of traditional Chinese medicine, the malignant tumor is a western medicine disease name, the concept of accumulation and the like of the traditional Chinese medicine exists in a containing relation, a pulse instrument is a main way for researching by using objective pulse conditions, and the characteristic extraction of pulse condition signals is also a trend for researching the pulse conditions of patients with the malignant tumor. The disadvantages are: the pulse condition of the traditional Chinese medicine is not fused with medical equipment such as 'CT', nuclear magnetism and the like of Western medicine, the characteristic pulse condition of malignant tumor is not found, and the result of the Western medicine is not mutually verified.
