Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings.

[0018] Such as figure 1 As shown, a low-power electronic sphygmomanometer is characterized in that: it includes an MCU and a data acquisition module connected to the MCU, a storage module, a display module, an air circuit control module, and a power supply module for supplying power to the system; the MCU adopts the U.S. MSP430 series MCU produced by Texas Instruments (TI).

[0019] The MSP430 series MCU is a 16-bit ultra-low-power MCU produced by Texas Instruments (TI), of which MSP430F149 is an ultra-low-power Flash microcontroller that consumes only as much power as other flash microcontrollers (FlashMCU) one-fifth of. MSP430F149 is embedded with 12-bit A / D converter,

[0020] Can access 8 analog signals. And perform A / D conversion on one of them. The 12-bit A / D has a general sample / hold circuit, which provides users with various choices of sampling timing. In...

Abstract

The invention discloses a low-power-consumption electronic sphygmomanometer. The low-power-consumption electronic sphygmomanometer comprises an MCU, a data acquisition module, a storage module, a display module, a gas circuit control module and a power supply module which provides power for a system, wherein the data acquisition module, the storage module, the display module and the gas circuit control module are connected with the MCU, and an MSP 430 series single-chip microcomputer which is produced by American Texas Instrument (TI) is adopted by the MCU. According to the low-power-consumption electronic sphygmomanometer, low-power-consumption elements are adopted during designing, and a quite low system service voltage is adopted; meanwhile, due to the fact that the whole electronic sphygmomanometer is packaged by means of the SMT, the electronic sphygmomanometer is light, exquisite and convenient to carry. Therefore, the electronic sphygmomanometer is low in power consumption, convenient to carry, and practical.

Description

technical field [0001] The invention relates to a low-power electronic sphygmomanometer, which belongs to the field of medical equipment. Background technique [0002] Blood pressure is one of the important indicators of human health, which can reflect the functional status of the human heart and blood vessels. There are two methods of blood pressure measurement: direct method and indirect method. The direct method is an invasive method of measuring blood pressure by inserting a catheter through the skin into a blood vessel or heart at the predicted location. This method has the advantages of accurate measurement value and continuous measurement, but its invasiveness brings a lot of inconvenience to patients and clinical applications. The indirect method is a non-invasive measurement method, which uses the relationship between the intravascular pressure and the blood flow change at the time of vascular blockage to measure the corresponding pressure value from the body ...
