Medical Isolated Power Supply Systems in MICU Wards

In a medical environment, especially in the Medical Intensive Care Unit (MICU), the reliability and safety of the power supply are crucial. To ensure the stable operation of equipment in the MICU and to safeguard patient safety, the medical isolated power supply system has become an indispensable device. This article will explore the application of the medical isolated power supply system in MICU wards and its critical roles.

Basic Components of the Medical Isolated Power Supply System

The medical isolated power supply system mainly comprises the following core components to ensure the safety and reliability of the power supply in the MICU:

Medical isolated Transformer

The medical isolated transformer converts the commonly used municipal power system (e.g., TN-S system) into a medical IT system. By isolating the power from the ground, the transformer ensures that only the exposed conductive parts of the equipment are grounded, thus avoiding the risk of electric shock. This configuration improves the reliability of the power system, especially in high-risk areas like the MICU.

Medical Insulation Monitor

The medical insulation monitor provides real-time monitoring of the insulation status of the power system. It can measure insulation resistance, transformer temperature, and load changes. If the insulation resistance drops below a set threshold, the system automatically cuts off power to ensure the safety of personnel and equipment. This function is crucial in the MICU, effectively preventing potential dangers caused by electrical faults.

External Alarm Unit

The external alarm unit receives signals from the insulation monitor and issues an audible and visual alarm upon the first ground fault. While the system remains powered, maintenance personnel are alerted by the alarm to promptly address the fault, ensuring the continuous and stable operation of equipment in the MICU.

Current Transformer

The current transformer monitors the load current in the system and triggers an alarm if the current exceeds the set value. This helps maintenance personnel promptly detect abnormal current issues, thereby protecting the electric equipment and patient safety in the MICU.

Insulation Fault Locator

The insulation fault locator plays a key role in the medical IT isolated power supply system. It monitors the insulation status of the system in real-time and quickly locates the fault when it occurs. This function is particularly important in the MICU, allowing for rapid resolution of electrical issues, reducing maintenance time, and ensuring the safety of equipment and patients.

Core Advantages of the Medical Isolated Power Supply System

Ensuring Continuous Power Supply for Medical Equipment

The medical isolated power supply system avoids high fault currents through its ungrounded power supply method. Even in the event of a leakage, the resulting capacitive leakage current is very small, posing no harm to the human body. This ensures the stable power supply to medical equipment in the MICU, safeguarding patient life.

Enhancing Patient Safety

The medical isolated power supply system effectively prevents leakage current from flowing into the equipment in the MICU through the grounding line. As a result, patients will not suffer electric shock when touching the equipment, thus enhancing patient safety.

Improving Fire Safety of the Distribution System

The medical isolated power supply system reduces ground leakage currents, thereby decreasing the risk of fire. This design significantly enhances the fire safety of the entire power system, providing critical safety assurance in the MICU.

Ensuring Safety of Maintenance Personnel

During equipment inspection or maintenance, the medical isolated power supply system’s ungrounded loop design effectively avoids the risk of electric shock for maintenance personnel. This greatly enhances the safety of maintenance personnel even during powered repairs.

The application of the medical isolated power supply system in the MICU ward significantly improves the safety and reliability of the power supply. Through its core components and unique design, this system not only ensures the normal operation of medical equipment but also protects the safety of patients and maintenance personnel. In high-risk medical environments like the MICU, the medical isolated power supply system is undoubtedly key to ensuring safe and stable operation.
