Test Solutions for Medical Equipment (Part 2/3)

As the global population ages and the number of individuals requiring medical attention increases, there is a growing need for advanced medical equipment. This surge in demand has propelled significant expansion in the medical electronics market, especially for high-end devices like CT scanners, MRI machines, and high-end ultrasonic diagnostic instruments. In response, manufacturers of medical electronic equipment are ramping up investments and fostering innovation to meet these market needs.

Following the development of the medical electronics industry, we offer high-precision, high-speed, high-power-density battery simulators, AC/DC power supplies, AC/DC electronic loads, power analysers, and other test instruments. Our solutions provide accurate, efficient, and energy-saving testing solutions for various medical electronic applications.

Portable medical devices such as pacemakers, ultrasound equipment, monitors, rehabilitation robots, blood pressure monitors, and oximeters heavily depend on batteries. This underscores the crucial necessity to validate battery performance. To address this, rapid verification of battery performance is indispensable, providing a definitive PASS or FAIL outcome. This assessment involves evaluating DC internal resistance, instantaneous discharge capabilities, and life decay to guarantee the durability and sustained operation of batteries in these critical medical devices.

Portable and wearable medical devices are designed to maximize compactness while extending standby and operational durations. As a result, minimizing power consumption is crucial, alongside having sufficient battery capacity. Test requirements entail measuring standby and operational power consumption, including screen-on and screen-off scenarios. Precise measurements are needed, potentially reaching levels as low as nanoamps (nA), to ensure optimal power efficiency and prolonged device longevity.

Portable medical devices play a crucial role in continuously monitoring and tracking patients' conditions. This collected health data can be accessed remotely by medical professionals through a smartphone app, enabled by a Bluetooth connection. These wirelessly connected portable and wearable medical devices are particularly essential for delivering services to outpatients. Test requirements involve measuring power consumption of the portable medical device in various modes and functions, both when activated and deactivated in Bluetooth connection mode.

Medical equipment often directly interfaces with patients' organs or tissues, including devices like cardiac puncture monitors, ultrasound machines, maternal and infant monitors, baby warmers, and life 
monitors. Ensuring the stable operation of these devices is critical for patient safety and health. The power supply significantly influences stability, necessitating rigorous testing of the power module in medical equipment. Test criteria typically include IEC anti-interference tests such as voltage dip, short-term interruption, and voltage change, alongside leakage current detection. Devices under test (DUT) commonly comprise power modules (AC-DC/DC-DC) and power adapters, with testing procedures governed by regulations like EN6060-1, IEC60601-1, and IEC61000-4-11.
