Title:

ELECTRICAL MEANS TO LIMIT LEAKAGE CURRENT IN BATTERY OPERATED PATIENT-CONNECTED MEDICAL DEVICES

Document Type and Number:

WIPO Patent Application WO/2012/110913

Kind Code:

A3

Abstract:

A system (116, 120) for electrically limiting leakage current in a patient- connected medical device (100). The system (116, 120) includes a first set (116) of one or more switching devices (118) that selectively connect a first power output (124) of a battery compartment (110) of the patient-connected medical device (100) with a first power input (126) of electronic components (102) of the patient-connected medical device (100) based on a first polarity of input voltage from the battery compartment (110). The system (116, 120) further includes a second set (120) of one or more switching devices (122) that selectively connect a second power output (128) of the battery compartment (110) of the patient-connected medical device(100)with a second power input (130) of the electronic components (102) based on a second polarity of the input voltage, wherein the first polarity is opposite the second polarity.
