Definitions

  • the invention relates to a method and an apparatus for carrying out the method for supplying measurement, control and regulation systems, in particular cardiac pacemakers, implanted in human body tissue with photovoltaic energy and the bidirectional data transfer between them and an exogenous evaluation and control module with an encoder-receiver display , for the maintenance and support as well as measurement and diagnosis of organ and body functions.
  • Systems of the type described are used in various implanted electromedical devices, such as tissue stimulators, insulin control systems and others.
  • Such devices are assigned an ever increasing number of complex functions in order to make them more effective in their therapeutic and diagnostic efficacy as well as simple and tolerable use.
  • the quality of life of their wearers is influenced by these devices to a not inconsiderable extent, or their life is extended.
  • the duration of the functionality of the systems implanted by surgery alone is of considerable importance to the patient and, as a result, essentially depends on the possible energy supply of the systems.

  • Such a pacemaker correlatively adjusts the heartbeat rate according to a fixed, predetermined pattern via the blood oxygen value determined and thus no longer meets the latest requirements, which, for example, enable input of control commands in the case of changes in the stress caused by the circulatory system or diagnosis of physical functions via data feedback .
  • DE-OS 36 05915 describes a control and power supply unit for implanted electromedical measuring, control and regulating systems with an electronic unit, the energy requirement of which is generated photovoltaically by solar cells. These are not implanted, but rather are arranged on preferred parts of the body so that there is no galvanic connection between them and the implanted electronic unit. Rather, the solar cell energy is transmitted inductively via a transmission system with a primary winding that can be attached to parts of the body and an implanted secondary winding, and is supplied to the implanted electronic unit via lines inserted into blood vessels. The transmission system also provides a bidirectional data transfer between a control panel fed directly by the solar cells for issuing control commands and the implanted measuring, control and regulating system with the electronic unit.
  • the problem which is to be solved by the invention is to demonstrate a method and a device for supplying implanted MeR, control and regulating systems with photovoltaic energy and the bidirectional transfer of oats between these and exogenous evaluation and control modules which show the impairments of the Minimize patients with regard to implantation and during use, reduce the expenditure on equipment and surgery, reduce the susceptibility to electromagnetic fields and the transmission losses.

Abstract

L'invention vise à minimiser les troubles qui affectent les patients lors de l'implantation et pendant l'utilisation, à réduire la complexité technique au niveau des appareils et de l'exploitation, ainsi qu'à réduire la sensibilité aux parasites par rapport aux champs électromagnétiques, ainsi que les pertes de transmission. Des cellules solaires (5) implantées sont soumises à une radiation lumineuse dans le domaine spectral du visible et/ou de l'infrarouge, qui a une incidence sur la surface de la peau, dans la région d'une zone dermique d'immission lumineuse (18), et pénètre la surface de la peau ainsi que les tissus organiques (16) diaphanes, sur la trajectoire menant aux cellules solaires (5), avec des pertes d'absorption. Le transfert de données bidirectionnel s'effectue sur la même trajectoire à l'aide d'une lumière à commande modulée des plages de longueur d'onde comprises entre 800 et 900 nm ou entre 1250 et 1350 nm, ou bien entre 1450 et 1550 nm par technique de génération de la lumière, entre un élément d'émission de lumière (4) optoélectronique exogène, fixé de manière flexible au-dessus de la zone dermique d'immission lumineuse (18) et un élément de réception de la lumière (3) optoélectronique implanté, avec un inversement possible des fonctions entre les deux éléments (4, 3). L'invention concerne en outre des appareils électromédicaux implantés, qui servent à maintenir et à préserver des fonctions organiques et physiologiques, ainsi qu'à les mesurer et à établir des diagnostics les concernant. Ces appareils peuvent être des stimulateurs tissulaires, des systèmes de régulation du taux d'insuline, notamment des stimulateurs cardiaques (2).
