Embodiment 1

[0042] Embodiment 1, measure pulse signal and diastolic pressure by decompression method

[0043] The present invention is a kind of blood pressure measuring device, and described blood pressure measuring device comprises cuff 8 and the host computer 4 that is connected with described cuff 8, and described cuff 8 is double-airbag fan-shaped cuff, and described double-airbag fan-shaped cuff is A cuff bound on the measured limb with double trachea and double inflatable bags of upstream air bag 1 and downstream air bag 2, the upstream air bag 1 and the downstream air bag 2 are respectively located upstream and downstream of the arterial blood flow of the measured limb After binding, the upstream airbag 1 is fixed at the upstream of the wrist pulse to block the blood flow of the elbow artery of the subject, and is connected with the upstream airbag interface on the host 4, and the downstream airbag 2 is fixed downstream of the arterial blood flow direction The part detects the wri...

Embodiment 2

[0109] Embodiment 2. Device and method for measuring systolic blood pressure and pulse signal using decompression method

[0110] The device of the present invention is also applicable to the detection of pulse signals of systolic blood pressure,

[0111] A control and data processing program is set in the microprocessor, and the control and processing program executes a blood pressure measurement process including the following steps:

[0112]A) pressurizing the downstream air bag 2 to a pressure value between the measured arterial systolic pressure and diastolic pressure, or a pressure value between the average blood pressure value of the measured artery minus 10mmHg and the average blood pressure value plus 20mmHg, or A pressure value, so that the amplitude of the pulse signal detected in the downstream airbag 2 is greater than a given value at this pressure value;

[0113] B) Pressurizing the upstream air bag 1 to a pressure value higher than the measured arterial systoli...

Abstract

The invention relates to a blood pressure measurement apparatus. The blood pressure measurement apparatus comprises a sleeve and a host connected with the sleeve. An upstream balloon and a downstream balloon are located on the flowing upstream and the flowing downstream of artery blood of the detected body, the downstream balloon is used for detecting change information of pulse signals, blood flow pulse changes caused by pressure changes of the upstream balloon are sensed in real time, and a microprocessor controls an air pump and an air release valve and processes pressure values, pulse signals or pressure values and pulse signals of one or two of the upstream balloon and the downstream balloon, wherein the pressure values, the pulse signals or the pressure values and pulse signals of one or two of the upstream balloon and the downstream balloon are detected by one or two of a first pressure sensor and a second pressure sensor respectively or simultaneously. According to the blood pressure measurement apparatus, the two inflating balloons are bonded to the limbs to perform pressurizing, pressure and pulse signals in the blood pressure measurement apparatus can be effectively detected, and thus blood pressure can be measured accurately and reliably, and measurement results are stable.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a method for detecting arterial blood pulse signals and a blood pressure measuring device using the method, especially a method for simultaneously controlling the upstream and downstream blood flow of a limb through two inflatable airbags. A method for detecting pressure and pulse signals and a blood pressure measuring device based on the method. Background technique [0002] One of the most commonly used methods of blood pressure measurement is to use a cuff with an inflatable air bag, which first blocks the arterial blood flow of the limbs of the human body through pressurization, and then slowly decompresses. The Korotkoff sound generated when blocking the area, or the change value of the pulse wave signal strength generated by the arterial pressure in the cuff, determines the systolic and diastolic blood pressure of the arterial blood.
