Medical Monitor Solution based on MYIR's T507-H SoM Module

Medical monitor is a guardian instrument for monitoring life signals. Studies have shown that the elderly need to be vigilant about "silent hypoxia" during the COVID-19 infection. Elderly patients may suffer from "silent hypoxia" because they are slow to respond to hypoxia after infection with the COVID-19. Family members may think that the elderly person's breathing status seems to be quite stable, but the blood oxygen saturation may already be at a low level. For the elderly, they need to closely monitor their overall body condition, including heart rate, blood pressure, breathing, blood oxygen saturation, etc., and seek medical attention in time for deterioration. The earlier the treatment, the greater the success rate of treatment.

A medical monitor is a device or system that can measure a patient's dynamic physiological parameters, compare them with known setting values, and give an alarm if an anomaly occurs. With the rapid development of the medical industry, many hospitals have accelerated the process of information construction. The hospital information construction needs the information and digital iteration of medical equipment. The traditional monitor has begun to develop into an information monitor. The monitor that integrates patient vital signs monitoring, clinical information processing, data interaction and equipment information will bring great help to the majority of medical staff in their daily clinical medical activities.

Through the medical sensor module, the ECG signal, heart rate, oxygen saturation, blood pressure, respiratory rate and temperature of the human body can be detected in real time. The system converts biomedical signals into electrical signals through signal detection and preprocessing module, and then samples and quantizes through data acquisition and processing module, and analyzes and calculates each parameter. The analysis result is compared with the threshold value, and the supervision alarm is made. The test results can be displayed, stored and printed locally, and transmitted to HIS system of the hospital through the network for information management.

The medical monitor mainly has three parts: signal acquisition, data processing and information display. The signal acquisition part mainly collects human biological signals through sensors and converts them into electrical signals. The data processing part is responsible for analyzing the collected data and comparing the data. The information display part mainly displays the ECG waveform and various parameters through the built-in display screen, which can be printed directly when equipped with printing equipment and transmitted to HIS system through the network.

The embedded CPU modules are widely used in a variety of medical devices due to the advantages of high performance, excellent stability and compatibility, which can effectively improve the accuracy of medical equipment. MYIR's MYC-YT507H CPU module uses the Allwinner automotive grade processor T507-H, which has the characteristics of strict quality standards, high performance, rich peripheral resources, cost-effective and stable supply, and is suitable for multi-parameter medical monitor solutions.
