DWIN Hematomanometer Solution Based on T5L0

1 Operating principle
Hematomanometer is a medical device that combines modern electronic technology and the indirect measurement principle to measure blood pressure, mostly using the oscillometric method.
Portable hematomanometer for home use is mainly composed of MCU, display panel, air pressure sensor, cuff, air pump, battery, etc.
Its operating principle is to calculate the systolic pressure, diastolic pressure and average arterial pressure according to the fluctuations of blood pressure in the arterial blood vessels during the decompression of the air cuff.

2 DWIN hematomanometer solution
The solution adopts T5L0 as the control center of the hematomanometer measurement and display, and monitors the fluctuations of blood pressure in the arterial blood vessels through the CFSensor pressure sensor XGZP6829D
040KPG with temperature compensation.
After that, it converts data into frequency to processes it by filtering algorithm.

Then it calculates the systolic pressure, diastolic pressure and average arterial pressure, and drives the 4.3-inch 800*480 resolution LCD panel to display blood pressure value and pulse count.

At the same time, the measurement results are delivered by voice broadcast.

3 Feature

a) Accurate: precise calculation of systolic and diastolic blood pressure values using filtering algorithm. Display accuracy of 1mmHg (0.133Kpa).

b) Intelligent pressurization: built-in 24-bit high-accuracy digital air pressure sensor, precisely controlling the inflation and deflation of the pressure pulse belt, effectively eliminating measurement artifacts.

c) Voice broadcast: support volume adjustment and automatic voice broadcast of measurement results.

d) Large memory: support for two-person use and 800 sets of history query per person.

e) Rich HMI elements: By DGUSII HMI 0 code secondary development, you can achieve real-time curve display of blood pressure values, high and low pressure warning, brightness adjustment, etc.

f) Rechargeable: built-in lithium battery with mini USB, easy to charge and without battery replacement.
