SYSTEM FOR CONTROLLED ADMINISTRATION OF A SUBSTANCE FROM A HUMAN-BODY-IMPLANTED INFUSION DEVICE

摘要

A system for the controlled administration of a substance by means of an infusion device implanted in the human body comprising an implantable unit (200) for detecting a shortage or an excess of such substance or a physiological parameter correlatable to the shortage or excess of such substance, an infusion group of this substance (100) implantable in the peritoneal cavity and comprising a central control unit (105) for processing data received from the detection unit (200) in order to generate command signals for the release of the substance in the intraperitoneal cavity, energy storage means (106) to power said infusion group (100). The system also comprises a carrier of said substance (500) adapted to be ingested in order to passively reach the duodenal lumen, made of perforable material resistant to gastric acids and with parts in magnetizable metal, and a refilling device (103) for refilling the infusion group (100) with said substance, comprising a magnetic reversible docking group (113) for said carrier (500), facing the duodenal lumen and actuable when said carrier reaches a predetermined distance therefrom, and means (120) for drawing the substance from said carrier communicating with suction means (110) of said infusion group (100).
