Medical electrical equipment symbols
Marks on medical electrical equipment (IEC 60601-1): the applied-part types B, BF and CF, their defibrillation-proof versions, and the sign telling users to follow the instructions for use.
Defibrillation-proof type CF applied partMedical electrical equipment symbolsDefibrillation-proof type CF applied partMarks a type CF applied part, for direct contact with the heart, that is also defibrillation-proof under IEC 60601-1, meaning it is built to withstand a defibrillator discharge given to the patient while it is connected. The paddles on either side of the frame show the defibrillation-proof rating.On IEC 60601-1
Follow instructions for use (read the manual)Medical electrical equipment symbolsFollow instructions for use (read the manual)A mandatory sign on medical electrical equipment: the instruction manual or booklet must be read before the equipment is used. On the equipment itself it is printed as a blue safety sign (ISO 7010 M002); it is shown here in black and white.On IEC 60601-1
Type B applied partMedical electrical equipment symbolsType B applied partMarks a type B applied part under IEC 60601-1, the part of the equipment that touches the patient in the least strict protection class against electric shock. Type B parts are generally not conductive, can be released from the patient immediately, and may be connected to earth.On IEC 60601-1
Type BF applied partMedical electrical equipment symbolsType BF applied partMarks a type BF (body floating) applied part under IEC 60601-1, the part of the equipment that touches the patient. It is used where the part has conductive or longer-term contact with the patient and is floating, meaning separated from earth; it is stricter than type B and less strict than type CF.On IEC 60601-1
Type CF applied partMedical electrical equipment symbolsType CF applied partMarks a type CF (cardiac floating) applied part under IEC 60601-1, the strictest protection class against electric shock. It is used for parts that make an electrical connection directly to the heart, and it is floating, meaning separated from earth.On IEC 60601-1
