Zusammenfassung: | Glaucoma drainage implant system with intraocular pressure sensor (IOP) and microvalve, and external reading unit, characterized in that it comprises: (1) an ocular implant device (1) comprising a main body attached to a cannula (3) with an inlet port (4) which communicates through a microchannel (10) that passes through said cannula with a microchamber of the sensor (11) on which one or more sensors (5) are located; said microchamber is in fluid communication with a microvalve (2) which regulates the passage of ocular liquid to an outlet port (7), where the microvalve (2) is covered by a plate in said main body, the implant device also includes a flat coil (6) for energizing the sensor(s) and the microvalve and a microchip (12) for regulation of a microvalve actuator and signal processing and modulation generated by the sensor(s); and (2) an external reading unit (UEL) (13), which acquires and processes signals from the IOP sensor (5) and presents the IOP pressure data on a screen; the UEL (13) mainly consists of two parts: an antenna and a main unit; where the antenna feeds bursts of RF radio frequency energy to the implant sensor (5) and when the sensor (5) is energized, it returns a signal with information from the IOP, this signal being received by said antenna and sent to the main unit for processing.
Sistema de implante de drenaje para glaucoma con sensor de presión intracular (PIO) y mieroválvula, y unidad de lectura externa caracterizado porque comprende: (1) un dispositivo de implante ocular (1) que comprende un cuerpo principal adosado a una cánula (3) con orificio de entrada (4) el cual se comunica a través de un microcanal (10) que atraviesa dicha cánula con una microcámara del sensor (11) sobre la cual se encuentra un sensor (o más)(5); dicha microcámara está en comunicación fluida con una microválvula (2) la cual regula el paso de liquido ocular a un orificio de salida (7), donde la microválvula (2) se encuentra cubierta por una placa en dicho cuerpo principal, el dispositivo de implante cuenta además con una bobina plana (6) para energizar el(los) sensor (es)y la microválvula y un microchip (12) para regulación de un actuador de la microválvula y procesamiento de señal y modulación generada por el(los) sensor(es); (2) una unidad externa de lectura (UEL) (13), la cual adquiere y procesa señales del sensor 5) de PIO y presenta los datos de presión de la PIO en una pantalla; la UEL (13) principalmente se compone de dos partes: una antena y una |
