Non-intrusion type charging system for artificial organ, capacitor and power supplying device used in the system
First Claim
1. A contactless charging system for an artificial organ characterized by comprising:
- (A) a storage device embedded as a whole in a body along with the artificial organ, and including power receiving coil means acting as a secondary side coil in a pair of coil means for transferring power, rectifying means for rectifying and outputting an AC received by the power receiving coil means, storage means for storing output from the rectifying means as electric power for driving the artificial organ, charge status detecting means for detect a charge status of the storage means, and charge status transmitting means for transmitting outside the body the charge status detected by the charge status detecting means; and
(B) a feeding device provided separately from the storage device and disposed as a whole outside the body, and including power transmitting coil means acting as a primary side coil in said pair of coil means, AC output means for outputting the AC to the power transmitting coil means, charge status receiving means for receiving the charge status transmitted outside the body from said charge status transmitting means, and charge status informing means for informing the charge status received by the charge status receiving means.

Abstract
According a charging system of this invention, an AC required for charging of an electric double layer capacitor of a storage device in the body may be transmitted from a feeding device outside the body through power receiving and power transmitting coils. The electric double layer capacitor may be charged in a contactless mode, without incising the body of the artificial organ user, while the storage device remains embedded in the body. The electric double layer capacitor may be charged reliably by avoiding a shortage of charging since the charge status of the electric double layer capacitor of the storage device is known during a charging operation.
