Title:
携帯に適した装置において電気的に絶縁されたパワーカプラシステムおよびデータカプラシステム
Document Type and Number:
Japanese Patent JP2006504380
Kind Code:
A
Abstract:
An electrically isolated combined power and signal coupler is usable for a portable medical monitoring device attachable to a patient in a medical environment. A power coupling system transfers power between a power source and a powered device separated by a physical and electrical isolation barrier. The system comprises a power coupler including in a first device, a first section of a magnetic circuit including a first core section of magnetically permeable material of cross-sectional area substantially larger at an isolation barrier interface than within a first winding located on the first core section. The first section of magnetic circuit being suitable, in a docking mode, for positioning adjacent to a second section of magnetic circuit in a second device to form a completed magnetic circuit used to transfer power between said first and second device. The second section of magnetic circuit including a second core section with a second winding magnetically coupling with the first winding via the completed magnetic circuit in the docking mode for the power transfer. The first core section comprises at least one substantially planar core section at the isolation barrier interface for positioning adjacent to a corresponding substantially planar core section of said second section of magnetic circuit at the isolation barrier interface to form the completed magnetic circuit without a device containing the second section of magnetic circuit enveloping a significant portion of the substantially planar core section.
