Embodiment 1

[0032] see picture figure 1 , Figure 11 , an electronic sphygmomanometer that can automatically calibrate zero and full scale, the electronic sphygmomanometer includes a microprocessor, a memory, a pressure detection unit, a pump valve control unit, a key input unit, a display unit and a power supply unit, the memory, The pressure detection unit, the pump valve control unit, the key input unit, the display unit and the power supply unit are all connected with the microprocessor. The microprocessor refers to a single-chip microcomputer with command execution function; the memory is a non-volatile ROM for storing pressure parameters, etc., which can be integrated in the microprocessor; the core component of the pressure detection unit can be composed of The ordinary analog pressure sensor constructed by Wheatstone bridge can also be a digital pressure sensor; the pump valve control unit is to amplify the microprocessor control signal to control the work (open) or stop (close)...

Embodiment 2

[0035] see figure 2 , Figure 12 , as an improvement of the present invention, in order to improve the accuracy of the high-pressure safety valve, the high-pressure safety valve 6

[0036] A bellows micro-opening safety valve is adopted, and the bellows micro-opening safety valve includes a valve 9, a thimble 10 and a bellows 8, and the bellows 8 is composed of two diaphragms, namely an upper diaphragm 8.1 and a lower diaphragm Sheet 8.2, the specific method is to evenly apply solder paste on the inner edge of one of the diaphragms, then align and stick the other diaphragm, put it in a tin furnace for high temperature treatment, and stick the two diaphragms together after the solder paste melts. To achieve seamless connection, the standard for checking whether the process is qualified is the airtightness of the bellows. The thimble, 10 is set on the bellows 8, that is welded at the center of the upper membrane 8.1. Its specific working principle is: there is an air port in...

Embodiment 3

[0037] Example 3: see Figure 3-Figure 10 , the automatic zeroing and automatic full-scale adjustment method of the electronic sphygmomanometer, the automatic zeroing steps are as follows: see Figure 10 , in normal mode, press the O / I key to measure blood pressure; when the number of measurements or the service life exceeds the preset value, or the MCU cannot read the data in the FLASH chip normally, the blood pressure monitor will remind the user to calibrate; at this time the user Simultaneously press and hold the O / I key and the M1 key for 5 seconds, and the electronic sphygmomanometer automatically enters the automatic calibration mode; see image 3 , after entering the automatic calibration mode, the zero point calibration is performed first, the MCU controls the air pump to stop working, the solenoid valve is opened, and the air circuit is connected with the outside air. At this time, the sensor collects the current pressure value and sends it to the MCU for storage. ...

Abstract

The invention relates to an electronic sphygmomanometer capable of automatically calibrating zero point and full scale. The electronic sphygmomanometer comprises a microprocessor, a storer, a pressure detection unit, a pump valve control unit, a button input unit, a display unit and a power source unit, and the storer, the pressure detection unit, the pump valve control unit, the button input unit, the display unit and the power source unit are all connected with the microprocessor. When a user considers that a current measured value is likely inaccurate already, an automatic calibration mode can be started, the electronic sphygmomanometer can automatically calibrate zero point and full scale, and measuring of blood pressure is performed after calibration is completed, so that accuracy and reliability of blood pressure measuring data are improved greatly.

Description

technical field [0001] The invention relates to an electronic sphygmomanometer, in particular to an electronic sphygmomanometer capable of automatic zero and full scale calibration, and belongs to the technical field of medical devices. Background technique [0002] At present, with the improvement of people's living standards, people's chances of suffering from high blood pressure have greatly increased. Compared with traditional mechanical sphygmomanometers, electronic sphygmomanometers are easier to operate and do not require professional doctors to operate. Users can complete blood pressure measurements at home, so more and more families choose to buy electronic sphygmomanometers. Buying an electronic sphygmomanometer is not a once-and-for-all matter. The most worrying thing is the accuracy of the sphygmomanometer measurement. Although each sphygmomanometer has been strictly calibrated before leaving the factory, with the increase in the number of uses and years of use,...
