Description

A smart blood pressure monitor

technical field

The utility model relates to the field of medical electronic equipment, in particular to an intelligent sphygmomanometer.

Background technique

Blood pressure is an important parameter to measure the health index of human body. In recent years, as people pay more and more attention to their health, experts from all walks of life have made more and more in-depth research on blood pressure measurement. Since the theory of blood circulation was put forward in 1628, experts in various fields have been conducting research on blood pressure measurement. Accurate measurement of blood pressure is the premise of quantitative analysis of abnormal blood pressure. There are many factors that affect human blood pressure, such as blood volume, degree of arteriosclerosis, heart function, endocrine, exercise, emotion, etc., but which factors and how much influence they have must rely on accurate measurement of blood pressure.

Traditional blood pressure cannot accurately reflect people's blood pressure during daily activities, rest and sleep. Most of the current sphygmomanometers use intermittent blood pressure measurement methods such as the Korotkoff sound method. These methods can only measure the blood pressure value of the subject at a specific moment, generally only two values of systolic blood pressure and diastolic blood pressure, so it is impossible to continuously monitor each stroke. Blood pressure changes.

Continuous ambulatory blood pressure measurement can monitor the change of blood pressure waveform for a long time, and provide effective basis for the diagnosis and treatment of diseases. In order to meet the diversified monitoring of people's health information and achieve certain social and economic benefits, it is necessary to research and develop a sphygmomanometer that can automatically detect pulse pressure signals on a limited hardware resource platform.

Detailed ways

Below in conjunction with specific embodiment, and in conjunction with accompanying drawing, the technical scheme of the utility model is further described:

Embodiment: an intelligent blood pressure monitor (see accompanying drawing 1), including: a physiological parameter acquisition module 1, a conditioning circuit module 2, an A/D conversion module 3, a main control module 4, a data analysis module 5, and a display module 6. Physiological parameter collection module 1 gathers the characteristic signal of human body; Said characteristic signal enters conditioning circuit module 2, completes characteristic signal amplification, filtering, anti-interference processing, then enters A/D conversion module 3; A/D conversion module 3 will It is converted into a digital signal, and then enters the main control module 4; the main control module 4 controls the digital signal, and on the one hand, the digital signal is input to the display module 6, and on the other hand, the digital signal is input to the data analysis module 5; the data analysis module 5 Various digital signals are received and analyzed to obtain the health status of the human body; the display module 6 displays the digital signals and the health status of the human body.

When the physiological parameter collection module 1 is a contact sensor, it is specifically DS18B20, TS51AC, 503ET NTC thermistor, and when the sensor is a non-contact sensor, it is OTP538U.

The display module 6 is an LED display screen, which is connected with the main control module 4 and used to display the measured physiological index and health status.

Since the signal obtained from the sensor is very weak and mixed with some other interference signals and noise, the main function of the preamplifier circuit is to filter out some common-mode interference signals and amplify the pulse signal without distortion. The system uses AD623 operational amplifier with high gain, high input impedance, high common mode rejection ratio and low noise to form the preamplifier circuit. The pulse wave signal is mainly concentrated in the frequency band of 0-40Hz, and the spectral characteristics are similar to the ECG signal, so we use the TLV2324 operational amplifier to design a second-order low-pass filter to filter the pulse wave signal to filter out high-frequency interference signals . In addition, before the signal is amplified again, a double-T band-stop notch filter is used to filter out 50 Hz power frequency interference.

The above-mentioned specific embodiments are used to explain the utility model, rather than to limit the utility model.
