Ultrasonic retina stimulation device

Abstract

The present invention discloses an ultrasonic retina stimulation device. The ultrasonic retina stimulation device comprises a spectacle frame and spectacle glasses; an ultrasonic transducer, a first data transmitter-receiver device, an energy receiving device and an integrated chip are disposed in each spectacle glass substrate; the spectacle frame is provided with camera devices, integrated circuits, second data transmitter-receiver devices, energy transmission devices and power supplies; the camera devices are used for acquiring image information; the integrated circuits are used for converting the image information into image data and transmitting the data to the integrated chips through the data transmitter-receiver devices; the integrated chips are used for converting the image data into stimulation signals; the ultrasonic transducers are used for performing ultrasonic stimulation on retinas under stimulation of the stimulation signals; and the power supplies supply the camera devices, the integrated circuits and the second data transmitter-receiver devices with power, and supply the integrated chips and the first data transmitter-receiver devices with power through the energy transmission devices and the energy receiving devices. When a visual function disorder wears the device, the ultrasonic transducers are stimulated to form focusing acoustic beams having a plurality of focuses, optic nerve cells are stimulated, and the visual perception function is recovered.

Description

technical field [0001] The invention relates to the technical field of visual replacement, in particular to an ultrasonic retinal stimulation device. Background technique [0002] With the development of society, more and more attention has been paid to the health of the disabled. Many blinding diseases are found today. The patient's lens is blurred or the surface cells of the retina can no longer work, but the cells below the surface are still healthy and alive. There are many blind prosthetics that use electrical stimulation to help blind people restore visual function, but electrical stimulation requires surgery to implant chips in the human body, which is far behind ultrasonic stimulation in terms of non-invasiveness and safety. [0003] The visual imaging process of the human eye is that the reflected light of the object is refracted and imaged on the retina through the lens, and then transmitted to the brain by the visual nerve perception. Thus, conditions causing bli...
