Digital manometer

Abstract

The invention provides a digital manometer, comprising a cuff, a manual pressure device, a degassing regulating device, a pressure sensor, a storage unit, a microprocessor, a display unit, an initiate key and a pressure locking key, wherein the pressure sensor detects the pressure in the cuff and sends a pressure signal to the storage unit for storing so that the microprocessor performs further calculation; the microprocessor is respectively connected with the initiate key, the pressure locking key and the display unit and comprises a pulse wave detection unit and a pressure collecting unit, the pressure collecting unit is associated with the pressure locking key and the display unit; and the display unit comprises a plurality of pressure display blocks used for displaying a plurality of heartbeat pressure values locked by the pressure locking key. The invention realizes that a plurality of pressure measurement values can be locked and displayed in a single measuring process and then can be used for correcting misjudgments or misoperations generated in measurement and auscultation and better accords with operating habits of a doctor.

Description

technical field [0001] The invention relates to a digital pressure gauge, in particular to a digital pressure gauge with a pressure locking function. Background technique [0002] 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 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 operation, and directly affect the accuracy of the measurement results. [0003] For this reason, the patent documents with the publication...

AI Technical Summary

Problems solved by technology

[0005] Only one systolic blood pressure and one diastolic blood pressure can be locked in one measurement process. If auscultation misjudgment or manual misoperation occurs, it cannot be corrected. You can only wait for the end of deflation before re-pressurizing the measurement, which does not conform to the doctor's measurement habits and will This results in an extension of the measurement time;

[0006] There is a certain delay between pressing the button and hearing the pulse beating sound, especially for the elderly, the delay may be longer, so there will be a certain error between the locked value and the actual corresponding pressure value, which will affect the accuracy of the measurement sex;

[0007] In addition, similar products on the market have single functions and provide limited measurement information
