Embodiment 1

[0060] Below to Figure 6 As an example, the method for measuring blood pressure of the present invention is described in detail. 1) The subject maintains a stable sitting posture and a pulse sensing device is set on the subject. Oxygen probes such as image 3 , the pulse sensing device is energized to measure the pulse wave of the subject. The pulse sensing device is connected to a single-chip microcomputer detection device and enters the computer through the NI USB-6211 data collector; 2) between the subject's heart and the end of the finger Two measurement points are set on any pulse wave transmission path, and the distance between one measurement point and the heart is greater than the distance between the other measurement point and the heart; the two measurement points are: a projected sensor clamped at the fingertip of the index finger and A reflective sensor is set at the wrist of the subject; 3) according to Figure 8 In the uploading method shown, the measurement v...

Abstract

The invention relates to a blood pressure noninvasive measuring method. The method comprises the following steps: 1) arranging a pulse sensing device on an examinee, wherein the pulse sensing device is used for measuring the pulse wave of the examinee and is connected to a single chip microcomputer detection apparatus; 2) setting two measuring points in any pulse wave transmission path from the heart of the examinee to the finger tip of the examinee, wherein the distance of one measuring point to the heart is greater than that of the other measuring point; 3) uploading the measured values of the pulse sensing device in the above measuring points to the single chip microcomputer detection apparatus to acquire two pulse wave measuring curves; and 4) acquiring a blood pressure measuring value according to a wave peak or trough conduction time difference in a same period in the two pulse wave curves. According to the method of the invention, the two pulse signals of any two points from the heart to the finger tip are directly measured, and the blood pressure value is obtained based on the linear relation between the pulse wave conduction time and the arterial blood pressure.

Description

technical field [0001] The invention relates to a device for measuring blood pressure, which is a method and device for measuring blood pressure by measuring pulse waves at any two points from the heart to fingertips. Background technique [0002] Since the establishment of blood circulation theory, the mystery of blood has been uncovered layer by layer. Blood is an important part of the survival of organisms, and blood circulation is related to the metabolism of the entire organism and the functions of life, old age, sickness and death. Nowadays, blood Research is getting more and more attention. [0003] For a long time, human beings have been looking for effective means of measuring blood pressure. From the research of direct measurement technology that started in the 19th century to the indirect measurement method that is widely used today, the measurement of blood pressure, an important physiological parameter of the human body, has become more and more mature and perfe...
