Figure 2-5. Patient environment
Commercial devices such as laser cameras, printers, VCRs and external monitors,
usually exceed allowable leakage current limits and, when plugged into separate AC
outlets, are in violation of patient safety standards. Suitable electrical isolation of such
external AC outlets, or providing the device with extra protective earth, will be required
in order to meet IEC60601-1 standards for electrical leakage.
Sub Clause 3.79 and figure A.9 (IEC60601-1:2005 and ANSI AAMI
ES60601-1:2005)
Such an area is an environment in which medical diagnosis, monitoring or treatment is
carried out. It is very difficult to attach unique dimensions to the PATIENT
ENVIROMENT.
In practice a distance of 2,5 m (8.2 ft.) above the floor on which the medical personnel
stand and a horizontal distance of 1,5 m (4.9 ft.) have justified themselves as
indicative of the dimensions of the Patient Environment.
The patient environment/vicinity will be depicted as a dashed line in this procedure.
See example below.
