Medical Applications based on STM32MP1 - Electrocardiogram (ECG) Monitor Solution

2020-6-30   17:37:38     Click: 705

This year, the epidemic Covid-19 strikes human beings badly and we are still fighting against it. The demand for medical equipment is soaring and this leads to challenges of public health facilities. Combined with years of experience in embedded software and hardware development, MYIR has introduced STM32MP1 based electrocardiogram (ECG) monitoring solution to help the construction of global medical facilities.

Cardiovascular diseases (CVDs) are the number 1 cause of death globally: more people die annually from CVDs than from any other cause. ECG (electrocardiograph) is the basic basis for the examination of such diseases, it is used for recording physiological electrical signals produced when the heart is active.

A complete ECG monitoring solution comprises of signal acquisition and processing, data transmission and analysis, image display, etc. The images displayed determine the doctor's diagnosis of the disease. The solution which MYIR has provided comprises of RGB / HDMI display + GigE + WiFi/BT from the MYD-YA157C development board which is based on ST’s first MPU STM32MP1 series processor, the software interface is made from MYIR's Yocto 2.6 based MEasy HMI 2.0 system. Users can develop their own applications based on this platform rapidly.

The MEasy HMI 2.0 is an HMI structure based on QT5 developed by MYIR. Its programming combines QML and C++. QML is used for building UI efficiently while C++ is used for realizing logic and complex algorithms. The structure can be divided into 3 layers: Hardware, kernel, application.

Below YouTube link displays the MEasy HMI QT DEMO on STM32MP1 based MYD-YA157C Dev Board with LCD & Touch Screen.

The entire UI can be divided into five categories according to the type of application: Health Care, Smart Home Appliances, Public Services, Multimedia and System. There are two options for main page display, one is rotation display based on PathView and the other is gridview based on SwipeView. Area 1 of rotation display as below picture is for language selection, area 2 is for appliance selection, area 3 is the button for switching between rotation display and gridview, and area 4 is for contact interface.

The principle of electrocardiograph: An electrocardiograph records electrocardiosignals automatically and converts them into digital signals, then transmits the signals to the control and processing unit to process and analyze, in the end the ECG is displayed on screen in real time. The ECG can also be transmitted wired or wireless to doctor’s office.

The ECG appliance of MYIR’s MEasy HMI 2.0 can display ECG waveform and parameters such as ECG, NIBP, SPO2, RESP, TEMP, etc. The parameters are refreshed every second.

User can leverage MYIR’s hardware platform to develop your applications. Below YouTube link displays the ECG DEMO on STM32MP1 based MYD-YA157C Development Board.
