Graphene multipoint pulse wave blood pressure monitoring intelligent wearing device

Abstract

The invention discloses a graphene multipoint pulse wave blood pressure monitoring intelligent wearing device which comprises a wearing device body for being worn on the human hand. The wearing device body is provided with a plurality of graphene pulse wave sensors for collecting pulse waves and a background noise sensor for collecting background noises. The intelligent wearing device is further provided with a circuit module connected with the graphene pulse wave sensors and the background noise sensor. The circuit module comprises a processing chip and a power supply for power supply. The number of the graphene pulse wave sensors is a plurality, the graphene pulse wave sensors are arranged at the positions of finger pulp of the left hand and the right hand and the wrist pulse positions. According to the graphene multipoint pulse wave blood pressure monitoring intelligent wearing device, not only can accurate pulse heart rate times and pulse wave feature information be obtained, but also a blood low velocity can be obtained by utilizing delay of pulse wave signals at three different positions, and a blood pressure value is obtained.

Description

technical field [0001] The invention relates to an intelligent wearable device that uses a graphene sensor to monitor blood pressure. Background technique [0002] With the development of social economy and the improvement of people's living standards, cardiovascular and cerebrovascular diseases have gradually replaced common infectious diseases and become the number one killer of human beings. Hypertension is the chief culprit of cardiovascular and cerebrovascular diseases, which has the characteristics of high incidence rate and low control rate. The normal blood pressure of an adult is about 120 / 80, and it can be dangerous if it is too high or too low. According to statistics, there are about 90 million hypertensive patients nationwide, and among them, only 4.1% of them have their blood pressure effectively controlled in urban areas, and only 1.2% in rural areas. Excessive blood pressure can damage important organs such as the heart, brain, and kidneys, causing disease,...

Problems solved by technology

Mercury column sphygmomanometers have higher measurement accuracy and stability, but because they need to be used with a stethoscope to monitor the sound, they have higher technical requirements for users; while electronic sphygmomanometers are mainly divided into wrist-type and arm-type, portable More convenient, it can automatically measure heart rate and blood pressure at one time, but this kind of sphygmomanometer will be subject to many restrictions, the noise of the surrounding environment, the up and down sliding and friction of the cuff, etc., may have a certain impact on the measurement results; the barometer type The sphygmomanometer is shaped like a clock and uses the mechanical action of the head to indicate the blood pressure reading. The rest of this sphygmomanometer is basically the same as the mercury column sphygmomanometer, but its accuracy is not as good as the mercury column sphygmomanometer

The common feature of these sphygmomanometers is that they are not very convenient to carry and have high technical requirements.
