Description

Blood pressure detection assembly, sphygmomanometer and blood pressure measuring method

Technical Field

The application relates to the field of blood pressure measurement, in particular to a blood pressure detection assembly, a sphygmomanometer and a blood pressure measurement method.

Background

When blood flows in a blood vessel, the lateral pressure against the blood vessel wall becomes the blood pressure. Blood pressure, usually referred to as arterial or systemic blood pressure, is an important vital sign. Blood pressure measurement is the main means for assessing blood pressure level, diagnosing hypertension and observing the curative effect of blood pressure reduction, and accurate blood pressure measurement is the basis of carrying out hypertension management at the basic level. Among them, hypotension usually means blood pressure lower than 90/60mmHg, and is commonly seen in patients with massive blood loss, shock and acute heart failure. Hypertension generally refers to the condition of adult systolic pressure being equal to or greater than 140mmHg or diastolic pressure being equal to or greater than 90mmHg without taking antihypertensive drug.

There are two main ways of measuring blood pressure, including direct measurement and indirect measurement.

The direct measurement method is that a catheter is sent to the aorta from the peripheral artery by percutaneous puncture, the end of the catheter is connected with a monitoring pressure measuring system, and the blood pressure value is automatically displayed. It is an invasive method and is usually only applicable to critical and difficult cases.

Indirect measurement is most commonly used, which is also known as cuff compression, and is usually measured with a sphygmomanometer. The sphygmomanometer is available in mercury column type, spring type and electronic sphygmomanometer.

Electronic sphygmomanometers have been widely used due to convenience and accuracy; the electronic sphygmomanometer is generally composed of an occlusion cuff, a sensor, an inflator and a measuring circuit, but the traditional electronic sphygmomanometer has the problems of large volume and complex structure, the length is generally more than 6 centimeters, and the width is generally more than 5 centimeters.
