Group 2 medical premises Group 2 are the most critical facilities where medical devices are used for heart-related functions; the failure of the medical device may cause immediate danger to the patient’s or staff´s life (operating rooms / intensive care).

Continuos monitoring in the OR In Finland, insulation monitoring system monitors all electrical devices

Insulation monitoring since 1981 • PPO-Elektroniikka was founded in 1981 to develop a system to improve electrical safety in operating rooms. Our first-generation insulation monitoring system MEV-2 was completed in the same year. • Our MEV-system brought up: The electrical failures were clearly a risk to patients, staff and operating room equipment. • At the request of hospital engineers, our first digital insulation monitoring device MEV-3 was launched in 1983. • MEV-3 -system revealed a big problem; there were many more medical devices with electrical current leakages than had been...

Mandatory in Finland since 1983 • No operation will be performed in Finnish operating rooms if insulation monitoring is not in use. • Insulation monitoring is required in all operating rooms and other critical care areas in all countries in the European Union since 2015

EN 61557-8 standard • A medical IT system must be used for final circuits supplying medical electrical equipment and plans for life support, surgical applications and other electrical equipment in these premises. • Installing at least one dedicated medical IT system is mandatory for each group of rooms serving a similar purpose. These systems must incorporate an insulation monitoring device (IMD) compliant with EN 61557-8 standards. • Furthermore, every medical IT system must feature an acoustic and visual alarm system strategically positioned for continuous medical and technical personnel...

Why is insulation monitoring needed? Prewarnings Extremely important in G2 medical premises, where the medical devices are used for cardiac-related functions. The medical device may pose an immediate danger to the patient, who is entirely dependent on equipment that ascertains vital functions. Old and new devices Electrical leakage currents occur in both old and new electrical devices due to malfunction, age and poor design. Common reasons for insulation faults include bad connections, damaged cable insulants and defective components. Fast technological development and the rush to launch...

MEV-system functions 24/7 in Finland • The electric power network of the operating room is separated from electrical grid with a medical isolation transformer. • The insulation-level monitoring system monitors all the electrical devices connected behind this transformer. Units control the insulation level of the IT system, the transformer load, and temperature as well as the continuity of protective earth 24/7. • The equipment indicates the faults and problems before dangerous situations arise. This gives time to replace the defective device without breaks in the operati

Safety, efficiency and cost savings The leakage of electrical current is an invisible killer without any visible signs. Insulation Monitoring System • • • • Protects the patients and personnel from electric shocks Prevents electrical fires and burns Ensures that unnecessary downtime can be avoided Ensures that the life of surgical equipment is extended. Acquiring insulation monitoring system is a long-term investment; the price is low in relation to the value. It is a matter of human life that cannot be measured in m

Operating room is full of electrical devices Serious hazards have to be prevented and minimized in every possible way. The obligation is both legal and moral. International Consortium of Investigative Journalists in 2019: “Manufacturers, doctors, and others potentially linked more than 1.7 million injuries and nearly 83,000 deaths to medical devices in reports to U.S. regulators over the last decade.” Insulation monitoring is one of the most efficient measures to prevent dangerous situation

Case example: Faulty equipment in the OR A faulty device connected The monitoring device detects fault and alarms An alarm shown in the OR wall panel The faulty device to repair/service Info to the maintenance team The faulty device removed A new device connected Operation continues

References in Finland Our MEV-insulation monitoring system is in use in all wellbeing services counties in Finland. Our solutions are delivered to hospitals directly or through hospital builders or central manufacturers. We also install and perform commissioning inspections. We have 21 self-governing wellbeing services counties with five University Hospitals. Also private hospitals use our systems.
