Power supply device of defibrillator using a Piezoelectric element and defibrillator having the power supply device

摘要

The present invention relates to a power supply of an implantable cardioverter defibrillator. The power supply is provided with a battery power supply state; Auxiliary power unit for a battery having the charging and charge the battery with the charging of the piezoelectric element; Selecting one of said main power supply and the auxiliary power unit according to the state of the battery for the charging of the auxiliary power unit and the power to the selected power supply voltage selector, the implantable defibrillator unit for providing group; and and having a. The auxiliary power unit includes a piezoelectric element which converts the output of the external vibration into electric energy; Rectifier circuit for converting an alternating current generated from the piezoelectric element to a direct current; A direct current voltage converted by the converter output to a constant value of the direct current output from the rectifier circuit; And a; and for charging the battery for the charging voltage supplied from the converter. ; According to the present invention, to extend the service life of implantable defibrillators, as well as to be able to reduce the number of times of unit replacement, it is possible to use a separate semi-permanently without battery replacement procedures.
