Abstract
(EN)
This in-vivo implantation-type electronic device (10A) is provided with a case (11), a power receiving coil (15), and an electronic circuit. The case (11) is formed from a biocompatible material and forms a sealed internal space. The power receiving coil (15) is arranged in the internal space of the case (11) and interacts with the electromagnetic field formed from an external electric field or magnetic field to receive power, or externally transmits electromagnetic waves. The electronic circuit is arranged in the internal space, is connected to the power receiving coil (15), and performs at least electrical signal processing. Further, the case (11) is provided with: a box-shape first member (111) which is formed from a metal-base biocompatible material and which has an opening; a second member (112) which is formed from a non-metal-base, biocompatible material and which has a shape that closes the opening; and an annular packing (115) which is arranged between the first member (111) and the second member (112).

Ce dispositif électronique de type à implantation in vivo (10A) est pourvu d'un boîtier (11), d'une bobine de réception d'énergie (15) et d'un circuit électronique. Le boîtier (11) est formé à partir d'un matériau biocompatible et forme un espace interne étanche. La bobine de réception d'énergie (15) est disposée dans l'espace interne du boîtier (11) et interagit avec le champ électromagnétique formé à partir d'un champ électrique externe ou d'un champ magnétique pour recevoir de l'énergie, ou transmet à l'extérieur des ondes électromagnétiques. Le circuit électronique est agencé dans l'espace interne, est connecté à la bobine de réception d'énergie (15), et effectue au moins un traitement de signal électrique. En outre, le boîtier (11) est pourvu: d'un premier élément en forme de boîte (111) qui est formé à partir d'un matériau biocompatible à base de métal et qui a une ouverture; d'un second élément (112) qui est formé à partir d'un matériau biocompatible à base non métallique et qui a une forme qui ferme l'ouverture; et une garniture annulaire (115) qui est disposée entre le premier élément (111) et le second élément (112).<b></b> <b></b>
