Description

Blood pressure detection assembly and sphygmomanometer

Technical Field

The present application relates to the field of blood pressure measurement, and 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 on the wall of the blood vessel becomes blood pressure. Blood pressure is often referred to as arterial blood pressure or systemic blood pressure, and is an important vital sign. Blood pressure measurement is a main means for assessing blood pressure level, diagnosing hypertension and observing antihypertensive efficacy, and accurately measuring blood pressure is a basis for developing hypertension management in the basic layer. Among them, hypotension generally means that the blood pressure is lower than 90/60mmHg, and is usually found in patients suffering from massive blood loss, shock and acute heart failure. Hypertension generally refers to an adult systolic or diastolic blood pressure of greater than or equal to 140mmHg or greater than or equal to 90mmHg without taking antihypertensive agents.

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

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

Indirect measurement methods, also known as cuff pressurization methods, are most commonly used, typically with blood pressure gauges. The sphygmomanometer includes mercury column type, spring type and electronic sphygmomanometer.

Electronic blood pressure meters have been widely used for convenience and accuracy; the electronic sphygmomanometer is usually composed of an occlusion cuff, a sensor, an inflator pump and a measuring circuit, but the traditional electronic sphygmomanometer has the problems of large volume and complex structure, and the length is usually more than 6 cm, and the width is usually more than 5 cm.
