Abstract:

A medical electrical equipment power supply is configured to satisfy at least one industry standard for patient leakage current. The power supply is provided with a plurality of electrical sockets into which IV pumps, patient monitors and other equipment may be plugged in. In one embodiment, the power supply has a housing configured to be mounted on an IV pole. An isolation transformer within the housing helps reduce the total patient leakage current to a value that satisfies at least one industry standard for patient leakage current. In another embodiment devoid of an isolation transformer, the power supply's electrical circuit detects whether the patient leakage current exceeds a predetermined value based on the industry standard, and disconnects power to one or more sockets so as to maintain the patient leakage current below this predetermined value.
