With the widespread application of electronic medical equipment in hospitals, the threat of leakage current to patients is becoming greater and greater, especially in places where life is critical. The patients are directly exposed to various electrodes and sensors during surgery or anesthesia. Inserted into the human body, even the slight leakage current may cause the patient to be electrocuted. In addition, some medical equipment is used to maintain the lives of critically ill patients. Once the equipment is powered off, it will also threaten the lives of patients. Therefore, for the electrical design of the special place of the hospital, the IT system should be used for power supply in strict accordance with national standards and regulations. This article introduces the application of Medical isolated power supply in Malaysia,

Keywords: Medical IT, Insulation monitor device, fault locator


1. Project Overview

Malaysia I.E.D is located in SELANGOR DARUL EHSAN, the project is mainly used in island hospital in Malaysia, the products are used for 12 circuit insulation fault location for 3 sets hospital isolated power system, the related products are insulation monitor device AIM-M200, signal test generator ASG150, centralized alarm indicator AID150, insulation fault locator AIL150-8, AIL150-4 and leakage current transformer AKH-0.66P26.

Medical IT system Introduction

ACREL medical IT system insulation monitoring device and fault location system is suitable for hospital operating room, ICU (CCU) and other important places, and can provide a safe place for such continuous, reliable power solutions.

Note: 1. In the operating room power distribution solutions, AID series of external alarm and display devices should be installed on the intelligence panel inside the operating room, or next to the intelligence panel (wall-mounted installation). During surgery, the medical staff monitors the health of the isolated power system.

2. In the scheme with insulation fault location function, if the number of located channels is more than eight, two sets of AIL150 locators can be used. The combination can be AIL150-8 and AIL150-4 (up to 12 channels), or AIL150 -8 and AIL150-8 (up to 16 channels).

Description

AITR series medical isolation transformer


AITR Series Medical Isolation Transformer Power Sensor

AITR series isolation transformer is specially used in medical IT systems. The windings are treated with double insulation and have an electrostatic shielding layer, which reduces electromagnetic interference between windings. The PT100 temperature sensor is installed in the wire bag to monitor the temperature of the transformer. The whole body is treated with vacuum invasion paint, which increases mechanical strength and corrosion resistance. The product has good temperature rise performance and very low noise.

AIM-M200 Medical Intelligent Insulation Monitoring Instrument Power Monitoring Device

AIM-M200 medical intelligent insulation monitoring instrument adopts advanced microcontroller technology, which has high integration, compact size, convenient installation and integrates intelligence, digitalization and networking in one. It is the ideal selection for insulation monitoring of isolated power systems in Class 2 medical locations such as operating room and intensive care units.
AKH-0.66P26 current transformer


AKH-0.66P26 Current Transformer Power Monitor

The AKH-0.66P26 type current transformer is the protective current transformer supporting the AIM-M200 insulation monitor, of which the maximum measurable current is 60A and the transformation ratio is 2000:1. The current transformer is directly fixed inside the cabinet by screwing, and the secondary side is led out by the terminal, which is convenient to install and use.
AIL150-4/AIL150-8 insulation fault locator


Ail150-4/Ail150-8 Insulation Fault Locator Power Monitoring Unit

AIL150-4/AIL150-8 insulation fault locator adopts high sensitivity transformer combined with a high precision signal detecting circuit, which detects the signal imported into the system from the ASG150 test signal generator and accurately locates the circuits which have insulation faults. AIL150-4 insulation fault locator can locate the insulation faults of 4 circuits, and the AIL150-8 insulation fault locator can locate the insulation faults of 8 circuits.
