Sphygmomanometer

Abstract

The invention discloses a sphygmomanometer. The sphygmomanometer comprises a cuff, a pressurizing and inflating unit, a deflating and adjusting unit, an acquiring unit, a storage module, a microprocessor, a power supply, a pressure locking module and a display module, wherein the acquiring unit comprises a pressure sensor and a pulse sensor, the pressure sensor is used for acquiring pressure in the cuff and transmitting a pressure signal to the microprocessor; the pulse sensor is used for detecting pulse wave and determining initial pressure of heartbeat every time; when the pressure locking module is pushed, the pressure sensor acquires an initial pressure value of the heartbeat at present; the microprocessor is used for transmitting initial pressure values, which are acquired by the pressure sensor, of pressure and heartbeat and transmitting the initial pressure values to the storage module; and a pressure value is calculated by analysis. By the sphygmomanometer, the pressure value can be accurately measured in an inflating and compressing process; by pressure locking and heart rate measurement, functions are powerful; the structure is simple; and the sphygmomanometer caters for detection habits of a user.

Description

technical field [0001] The invention relates to the field of sphygmomanometers, in particular to a pressure gauge with a pressure locking function and capable of shortening measurement time. Background technique [0002] With the aggravation of the population aging problem, family medical monitoring has a wider and wider market. As an important physiological parameter reflecting the state of the cardiovascular system and heart, blood pressure has become an important content of family medical monitoring. Although traditional mercury sphygmomanometers are considered the gold standard for measuring blood pressure, electronic sphygmomanometers have received widespread attention because they require training and are inconvenient to carry. [0003] Most of the existing hand-held electronic sphygmomanometers currently use the Keshi sound method for blood pressure measurement to replace mercury sphygmomanometers. The measurer uses a stethoscope to listen to the beating sound of th...

AI Technical Summary

Problems solved by technology

The measurer uses a stethoscope to listen to the beating sound of the pulse to judge the systolic and diastolic blood pressure. During the process of hearing the beating sound of the pulse, the measurer needs to observe the dial of the sphygmomanometer or the blood pressure value on the display screen with the naked eye to record the measured blood pressure. Systolic blood pressure and diastolic blood pressure, for those who have not received professional training, there are many inconveniences in the operation, and directly affect the accuracy of the measurement results
