Introduction

This document is the result of the many years of experience of ABB in the hospital sector and the day-to-day relationship with our customers who operate in this sector, which has made it possible to explore real world issues and applications in depth, while continuously comparing regulatory aspects with technical/installation aspects. We would like to thank all the ABB customers who shared their everyday experience with us for the great sensitivity shown in protecting the safety of the patients.

Why it is important to design and implement a system according to the standards

Before examining the ways in which systems for medical location are implemented, we provideanumberofdefinitionsthatwillmakeiteasiertounderstandtheremainingsections ofthisdocument.

2.1.3 Medical electrical system Combination of items of equipment, at least one of which is an item of medical electrical equipment and inter-connected by functional connection or use of a multiple portable socketoutlet. The system includes those accessories which are needed for operating the system and are specified by the manufacturer. Medical electrical systems are groups of multiple electromedical devices or of electromedicaldeviceswithothernon-electromedicaldevices,connectedelectricallyboth forthetransferofdataorsignals,andthroughtheirpowersupply.Oneexamplecouldbe a device that monitors the physiological parameters of a patient and transfers the correspondingdatatoanotherpieceofequipmentwhichinturnprocessestheminorder toprovideinformationusefulfordiagnosis.
