IEC60601-1 Edition 3.2 is the internationally recognized safety standard for medical electrical/electronic equipment. It covers the basic safety and essential performance requirements, in order to protect both operators and patients. It includes strict guidance for critical parameters, such as isolation voltages, creepage and clearance distances and leakage currents. Compliance with the standard is vital to prevent risk of electric shocks which could cause serious injury or even prove fatal. Effect Of Electric Shock On The Human Body The severity of an electric shock is determined by a number of factors, such as the level of current flowing An electric shock is the pathophysiological effect of an electric current passing through the human body. The severity of an electric shock is determined by a number of factors including the level of current flowing, the voltage present, the duration of the shock, the frequency (for ac), the condition of the human body and the location on the body to which the shock is applied. Dry skin has a relatively high resistance which, however, can vary considerably from person to person, but it is usually in the range 20-30kW/cm2. Wet skin and broken or punctured skin resistance is up to 100 times lower, thus significantly increasing the current flow for a given applied voltage. Internal body resistance is at a similarly low level. IEC60479-1 details the effects of current on the human body, which are characterized into 4 zones of current magnitude and duration of flow: Zone 1: Imperceptible Zone 2: Perceptible Zone 3: Reversible effects: e.g. muscular contraction Zone 4: Possibility of irreversible effects e.g. ventricular fibrillation IEC60601-1 imposes limits for types of leakage current A current of 50mA applied via a hand and passing through to earth by the foot is enough to cause ventricular fibrillation, if applied for 2 seconds or more – a weakened patient undergoing healthcare may be more susceptible. IEC60601-1 imposes limits for the different types of leakage current described below Therefore, IEC60601-1 imposes limits for the different types of leakage current described below. At this point it is important to note that a medical power supply is not considered to be a “Medical Device” within the meaning of the standard, but selection of a compliant product greatly simplifies the overall medical system design for the customer. Leakage Currents Leakage current is any current which has no functional purpose. It will flow from an intended circuit either to earth or a chassis for example. It can be generated due to a number of reasons, such as parasitic capacitance in a transformer, non-perfect insulators and capacitive coupling from EMC filter circuits. It not intended to be applied to a patient body and is therefore restricted to non-hazardous levels by IEC60601-1. Two types are relevant for medical power supplies: Earth Leakage Current and Touch Current (previously referred to as Enclosure Leakage Current in Edition 2). A third category, described below, is Patient Leakage Current, which is relevant for the end system. EARTH LEAKAGE CURRENT It flows from mains to Protective Earth (through or across the insulation). It does not flow through patient or operator touching. Maximum values: NC (Normal Condition) 500mA and SFC (Single Fault Condition) 1000mA TOUCH CURRENT It flows in normal use from a conductive part of the enclosure to earth through a conductor It flows in normal use from a conductive part of the enclosure to earth through a conductor, which is not the PE conductor, e.g. through operators and/or patients (excluding patient connections) Maximum values: NC (Normal Condition) 100mA and SFC (Single Fault Condition) 500mA PATIENT LEAKAGE CURRENT It flows from patient connections of the medical device (Applied Part) via the patient to earth or another part of the system enclosure, under NC (normal condition). But in the case of a SFC (single fault condition), the flow will be from the patient who may be connected to other sources of voltage) back to earth. Maximum values differ according to the type of Applied Part required (see definition below). Maximum values for B and BF type Applied parts NC: 100mA SFC: 500mA Maximum values for CF type Applied parts NC:10mA SFC:50mA What are applied parts? An Applied Part is defined as one that can be applied to, or be in direct contact with, the patient. There are three types of Applied Parts: Body (B), Body Floating (BF) and Cardiac Floating (CF). The medical device manufacturer will define the appropriate Applied Part category according to the intended application. Type B: Not intended to provide a current for diagnostic, treatment or therapeutic purposes. May be connected to PE. Equipment types include MRI/CT scanners, LED lighting and medical lasers. (REF NO 5840) Type BF: Intended for contact with the patient for diagnostic, treatment and therapeutic purposes but must not be connected to the heart directly or through the bloodstream. The patient is not directly connected to earth. Equipment types include Ultrasound machines, incubators, dental equipment, ventilators and blood pressure monitors. (REF NO 5333) Type CF: May be in contact with the heart either directly or indirectly via the bloodstream for example. Equipment types include Cardio electro surgery equipment and dialysis machines. (REF NO 5335) In summary, achieving compliant leakage current limits within a medical electrical system is challenging. Medical power supplies that meet lower than maximum levels of leakage current can significantly ease the task.
