The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
Referring to fig. 1, a portable dynamic cardiovascular parameter collecting device includes a cardiopulmonary sound collecting module 10, a blood oxygen collecting module 20, a pulse wave signal collecting module 30, an electrocardiographic signal collecting module 40, and a conversion processing module 50, wherein the pulse wave signal collecting module 30 and the electrocardiographic signal collecting module 40 are respectively electrically connected to the conversion processing module 50; the heart and lung sound acquisition module 10 is used for acquiring heart and lung sound signals, the blood oxygen acquisition module 20 is used for acquiring blood oxygen signals and outputting corresponding blood oxygen saturation parameters after conversion processing, the pulse wave signal acquisition module 30 is used for acquiring pulse wave signals, the electrocardiosignal acquisition module 40 is used for acquiring electrocardiosignals, and the conversion processing module 50 is used for converting the pulse wave signals and the electrocardiosignals into corresponding blood pressure parameters and heart rate parameters through a preset algorithm.
Specifically, the cardiopulmonary sound collection module 10 is configured to collect cardiopulmonary sound signals for preliminarily determining health conditions of the heart and respiratory organs. Blood oxygen acquisition module 20 is used to acquire a blood oxygen saturation parameter, which is the percentage of the volume of oxyhemoglobin in blood combined by oxygen to the total combinable hemoglobin volume, i.e. the concentration of blood oxygen in blood. The blood oxygen collecting module 20 performs spectrophotometry according to the principle that the amounts of light absorption of oxyhemoglobin and hemoglobin are different under the irradiation of 660nm red light and 940nm infrared light, so as to obtain a blood oxygen saturation parameter. When measuring, the person to be measured contacts with the blood oxygen collecting module 20 through the finger, so that the blood oxygen signal can be collected, and the operation is simple and convenient. The pulse wave signal acquisition module 30 realizes light capacity pulse wave acquisition by utilizing a three-color spectral method, the acquisition parameters are more accurate, and heart rate monitoring and ECG signal acquisition are combined, so that the error rate of dynamic blood pressure can be controlled within 5mmHg, and the accuracy of blood pressure measurement can be effectively improved.
Among them, an Electrocardiogram (ECG) is an important index for examining the whole process of cardiac pacing by recording the potential change of the cardiac cycle corresponding to the body surface. PhotoPlethysmoGraphy (PPG) is a non-invasive method of detecting changes in blood volume in living tissue by electro-optical means. When a light beam with a certain wavelength is irradiated to the skin surface, the light beam is transmitted to the photoelectric receiver in a transmission or reflection mode. In the process, the light intensity detected by the photoelectric receiver is weakened due to absorption attenuation of skin muscle tissue and blood. Wherein the absorption of light by skin, muscle and tissue is constant throughout the blood circulation, while the volume of blood in the skin pulsates under the action of systolic relaxation. When the heart contracts, the blood volume of the peripheral blood vessel is the maximum, the light absorption amount is also the maximum, and the detected light intensity is the minimum; when the heart is in diastole, on the contrary, the blood volume of the peripheral blood vessel is the minimum, the detected light intensity is the maximum, and the light intensity detected by the photoelectric receiver is in pulsatile change. Then the light intensity variation signal is converted into an electric signal, and the electric signal is amplified to obtain the variation of volume pulse blood flow.
Because the systolic pressure and the pulse wave transmission time present a good linear relation, the systolic pressure and the diastolic pressure are measured by an algorithm based on electrocardio signals (ECG signals) and photoplethysmography signals (PPG signals), the systolic pressure is measured by utilizing the existing wave velocity method, and the diastolic pressure is measured by combining the characteristic K value of the pulse wave with the elastic cavity model, so that the dynamic monitoring of the blood pressure is realized. The heart rate variability is reflected by the change of the heart rate along with time, so the heart rate variability is inversely proportional to the R-R interval, and the heart rate can be calculated according to the time-frequency characteristic of the ECG signal.
The portable dynamic cardiovascular parameter acquisition equipment can synchronously acquire parameters of human body such as heart and lung sounds, blood oxygen, pulse waves, electrocardio and the like, and simultaneously, the relationship between the pulse wave signals and the electrocardio signals can be utilized to calculate parameters of blood pressure and heart rate according to a preset algorithm.
