Vision recovery smart wearable device for patients with acquired blindness and manufacturing method thereof

Abstract

The invention discloses an intelligent wearing device for vision recovery of a patient with posteriority blindness and a making method thereof. The device comprises microelectrode arrays, a pair of intelligent glasses, earphones, elastic belt buckles and stimulating signal guide soft belts, wherein the microelectrode arrays are arranged in the eyes of the patient; the intelligent glasses, the earphones and the elastic belt buckles are arranged outside the eyes of the patient; the stimulating signal guide soft belts are arranged between the microelectrode arrays and the intelligent glasses. An outside image is shot by a microcamera arranged in front of the intelligent glasses and processed by a control system into a bidirectional electronic impulse signal, and the signal is transmitted by the stimulating signal guide soft belts to the microelectrode arrays arranged between the outermost layers of retinas and choroids to electrically stimulate ganglion cells; optic nerves transmit a biological signal generated by stimulation to a visual area of the cerebral cortex, are recognized by the brain and then make the blind patient restore part of visual performance to an outside object. The intelligent wearing device has the advantages of being good in stimulation effect, safe in use, attractive in appearance and convenient to wear.

Description

technical field [0001] The invention belongs to the field of bionic medical equipment, and in particular relates to an intelligent wearable device and a manufacturing method thereof for vision recovery of patients with acquired blindness. Background technique [0002] The eye is an important channel and window for human beings to understand the external world, and is the most complex organ and tissue in the human visual pathway. More than 70% of the information that human beings understand the world comes from the visual function of the eyes. According to the report of the World Health Organization in 2002, there are 140 million visually disabled people in the world, of which more than 45 million are blind patients, and there are 7 million new blind patients every year. expanding. Blind patients have great inconvenience and great pain in life, study and work. [0003] The visual pathway of the human body is: light → cornea → pupil → lens → vitreous body → retina (cone cell...

AI Technical Summary

Problems solved by technology

Wireless energy supply uses the principle of electromagnetic induction for energy transmission. Through high radio frequency, the electromagnetic induction coil system composed of the transmitting coil outside the body and the receiving coil inside the body generates induction electricity to provide electric energy; wireless energy supply is theoretically feasible. , which solves the technical problem of energy transmission, but the actual operation is very difficult: ①Due to the limited space size of the coil, the supplied energy is extremely limited

② Chips and coils will generate a lot of heat during charging, which will cause damage to surrounding tissues and easily cause discomfort to patients

③Biocompatibility and long-term stability of chip and coil materials with human tissue are not easy to solve

[0009] Retinal visual prosthesis technology, because the stimulation current intensity and frequency of the chip have been adjusted and solidified before implantation, and cannot be changed after implantation. It is a single system, and it is difficult to adapt to the individual needs of hundreds of blind blind people.

[0010] In addition, there are still problems such as the small number of electrode pairs of the microelectrode array and poor stimulation effect.
