Embodiment Construction

[0007] see figure 1 , the specific embodiment adopts the following technical solutions: it includes a power supply 1, a sensor 2, a cuff 3, a current regulator 4, a 16-bit Σ-Δ type A / D converter 5, an air pump 6, a keyboard display 7 and an air valve 8; The power supply 1 is connected to the sensor 2, the sensor 2 is connected to the 16-bit Σ-Δ type A / D converter 5, the cuff 3 is connected to the sensor 2, the air pump 6 is connected to the constant current device 4, and the keyboard display 7 is connected to the 16-bit Σ-Δ The Δ-type A / D converters 5 are connected to each other, and the gas valve 8 is connected to the 16-bit Σ-Δ-type A / D converters 5 .

[0008] In this specific embodiment, the oscillometric method is used for blood pressure detection. The main process is to obtain the changing pressure signal in the cuff, analyze the pulse signal separated therefrom, and find the positions corresponding to the systolic and diastolic pressures, thereby obtaining their sizes. ...

Abstract

The invention discloses a high-precision electronic blood pressure detector, relating to a blood pressure detector. The high-precision electronic blood pressure detector comprises a power supply, a sensor, a sleeve strap, a galvanostat, a 16-bit Sigma-Delta A/D (Analog/Digital) converter, an air pump, a keyboard display and an air valve; the power supply is connected with the sensor; the sensor is connected to the 16-bit Sigma-Delta A/D converter; the sleeve strap is connected to the sensor; the air pump is connected to the galvanostat; the keyboard display 7 is connected with the 16-bit Sigma-Delta A/D converter to each other; and the air valve is connected with the 16-bit Sigma-Delta A/D converter. The high-precision electronic blood pressure detector disclosed by the invention has the advantages of high hardware integration level, simpleness and convenience for design and implementation, integration of multiple advanced algorithms, such as morphological filtering and the like in software design, high accuracy, strong anti-jamming property, favorable precision and capability of meeting general requirements of blood pressure measurement.

Description

Technical field: [0001] The invention relates to a blood pressure detector, in particular to a high-precision electronic blood pressure detector. Background technique: [0002] Blood pressure is one of the important physiological parameters of the human body. Accurate measurement of it is conducive to early detection and identification of hypertension types and reasonable treatment suggestions. At present, non-invasive detection methods are mainly used clinically for ordinary patients, which are roughly divided into two types: artificial Korotkoff sound method and oscillometric method. Although the artificial Korotkoff sound method is relatively accurate, it is difficult to operate and is greatly affected by subjective factors. Although the traditional oscillometric method is simple to operate, its stability and individual adaptability are relatively poor, which is not conducive to its popularization and promotion in clinical application. Invention content: [0003] The p...
