Contact lens type wireless flexible electroretinogram signal detection system and method

Abstract

The embodiment of the invention discloses a contact lens type wireless flexible electroretinogram signal detection system and method. The system comprises energy transmission equipment and a contact lens type electroretinogram detection device, wherein the energy transmission equipment worn in front of the eyes comprises a signal generation circuit and an energy transmitting coil, and the energy transmission equipment acquires an electric signal and wirelessly transmits the electric signal to the contact lens type electroretinogram detection device; the contact lens type electroretinogram detection device worn on the surface of the eyeball comprises a signal acquisition electrode, an energy receiving coil and a signal processing main chip, and the energy receiving coil wirelessly receives the electric signal to drive the signal processing main chip; and an electroretinogram signal acquired by the signal acquisition electrode from the cornea is processed by the signal processing main chip and then is wirelessly transmitted to an upper computer to be displayed. By adopting the technical scheme of the embodiment of the invention, a set of huge electroretinogram detection system is concentrated on a contact lens type flexible device in combination with a flexible electronic technology and a signal processing main chip, so that a miniaturized and wireless visual electrophysiological instrument is realized.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of ophthalmology, and in particular, to a contact lens type wireless flexible electroretinogram signal detection system and method. Background technique [0002] Electroretinogram is an important diagnostic method for retina-related diseases in ophthalmic electrophysiological examination. Because of its high diagnostic accuracy and harmless to the body, it is a highly accepted ophthalmic examination method by doctors and subjects. [0003] However, the most advanced electroretinogram detection instruments commonly used in clinical practice are large, heavy, and costly, and waste medical resources; the wiring is cumbersome, and the wires need to be pasted on the subject's body in order to ensure that the wires do not move significantly. The disturbance will make the collected signal fluctuate greatly; the structure of the instrument is complex and consists of multiple components, and the...
