Embodiment 1

[0059] Embodiment 1 static blood pressure measurement

[0060] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiment 1.

[0061] Step 1: If figure 1 As shown, the inner fixing belt 12 is tightly wrapped around one side of the subject's limb, the sensor stabilizing structure 120 is closely attached to the artery, and the fixing belt 11 is tightened at the same time, ready to start the test.

[0062] Step 2: Start the test through the control button on the host 1, the start signal is transmitted to the fixed belt 11 through the wire 2, the inflation / deflation control unit starts to inflate, and multiple sensors in the multi-parameter physiological signal acquisition module synchronously record the inflation process various physiological signal parameters.

[0063] Step 3: stop inflating until the Korotkoff sound sensor 14 detects no Korotkoff sound vibration signal. The inflation / deflation control...

Embodiment 2

[0072] Embodiment 2 ambulatory blood pressure measurement

[0073] The test steps of this embodiment are consistent with those of Embodiment 1, and will not be repeated here.

[0074] The measurement device involved comprises: a multi-parameter physiological signal acquisition module (10), a signal processing module (20), a central processing module (30), a control module (50), a full waveform record display analysis module (60), a storage module ( 70), network module (80). Among them, the multi-parameter physiological signal acquisition module (10), the signal processing module (20), the central processing module (30), the control module (50), the storage module (70) and the network module (80) are all reasonably and effectively fixed on the outer layer belt (11). There is a display screen on the outer layer fixing belt (11), which can display information such as working status and parameter values.

[0075] The working principle of this embodiment is as follows.

Abstract

The invention provides a blood pressure measuring device, a method for effectively improving the blood pressure measuring accuracy on the basis of the measuring device and a method for judging moments of the closed state and the open state of an artery blood vessel. A blood pressure value is accurately obtained through continuous collection of Korotkoff vibration signals, detection of heartbeat periodic waveforms and extraction of fixing belt pressure signals. The problems that an existing sphygmomanometer is easily disturbed and the detection reliability is limited are effectively solved, a functional relationship of the Korotkoff vibration signals and the heartbeat period of the human body can be accurately and effectively recognized, and therefore the human body blood pressure accuracy value is accurately determined. The device can collect multiple physiological parameters at the same time, and provides data supports for related medical diagnosis and scientific research. The measuring device and method are applicable to the multiple fields of conventional blood pressure measurement, clinical diagnosis of related diseases of the heart, blood vessels, blood and the like, family health care and the like.

Description

technical field [0001] The present invention relates to a method and device for obtaining physiological parameters of a human body, in particular to a blood pressure measuring device, in particular to a measuring device based on continuous collection and recording of human Korotkoff sound vibration signals and a method for effectively improving the accuracy of blood pressure measurement. The invention also relates to a method for judging the moment of the closed state and the open state of the arterial vessel. Background technique [0002] Since the Russian doctor Nicolai Korotkoff used the appearance and disappearance of Korotkoff sounds to distinguish systolic and diastolic blood pressure in 1905, after more than a century, there has not been a blood pressure measuring instrument that truly meets the gold standard electronic discrimination in the world. Nicolai Korotkoff The proposed manual auscultation method is still the current accepted gold standard for non-invasive bl...
