Detailed description of the invention
The present invention just uses the apparatus and method of monitor heart rate and blood pressure on human body that this explanation embodiments of the present invention are described.
In human body artery, blood can produce fluctuation along with heartthrob.At body surface, this fluctuation also can be perceived, and simply has difference in the different perceived powers in position.The pulse-taking that the such as traditional Chinese medical science is familiar with is through perception radial artery, and to produce pulse amplitude at the diverse location such as cun, guan and chi, three places at the wrist where the pulse is usually taken of wrist different and realize.In fact, arteries and connected blood capillary all exist and the arteriogram produced because of heart contraction and diastole, this arteriogram is propagated at whole body with the speed close to 10m/s, all fluctuating with the identical rhythm and pace of moving things from the arterial capillary of big carotid artery to finger tip, ear end, here it is arteriogram, the pulse that namely people perceive at body surface is beaten.Arteriogram flowing in the blood vessel mainly produces two kinds of effects: one be arterial blood under the pump pressure of heart, arteries sidewall is produced pressure, this blood pressure i.e. typically referred to as；The second effect is because left ventricle to penetrate the blood volume that the blood initial stage pumps out big, is decreased to the closedown of relaxing period not at injection blood, and the most endarterial blood flow volume is also as heart contraction relaxation cycle and changes.Both changes are referred to as pulse wave, and the former is referred to as pulse pressure pulse wave, are obtained by the sensor-type pulse transducer of resistance pressure type, pressure-volume or piezo-electric type；The latter is referred to as blood and holds pulse wave, is typically obtained by photo-electric arterial volume sensor.No matter it is pulse pressure pulse wave or blood appearance pulse wave, contain and have substantial amounts of Human Physiology information, the rhythm and pace of moving things pulse frequency i.e. heart rate of arteriopalmus, the waveform change of pulse wave and rhythm and pace of moving things situation directly reflect the health status of the human circulation decorum, the contraction of such as tremulous pulse and diastole, blood vessel elasticity, acra microcirculation situation.Some pathological changes of human body also influences whether the rhythm and pace of moving things and the shape of pulse wave, such as hypertension, hyperlipidemia, and this is also one of physiology and the physical basis of pulse wave spectrum.
