Abstract

The invention discloses an artificial vision prosthetic device with a wireless energy transmission function. A wireless energy transmission module is used for wirelessly transmitting energy to eyes, and an image acquisition module is used for converting acquired analog signals into digital signals; a micro Bluetooth module is used for wirelessly sending the acquired digital signals to an in vitro image information processor and receiving in vitro transmitted control instructions, and a built-in controller is used for calling a micro rechargeable battery to supply power to each device in the eyes when the wireless energy is cut off; the transmitting terminal of the wireless energy transmission module is arranged on a spectacle frame body, and an external power supply is arranged in a spectacle leg and is used for providing a wireless energy transmission emitting terminal power supply. The artificial vision prosthetic device provided by the invention adopts wireless energy transmission and micro rechargeable battery to supply power, so that the supply of energy of each device in the eyes is ensured; and the wireless energy receiving terminal adopts an annular design which conforms to the human pupil shape, and can be applied to visual prostheses of all types.

Description

technical field [0001] The invention relates to a visual prosthesis device with wireless energy transmission function, in particular to an artificial visual prosthesis device with wireless energy transmission function. Background technique [0002] With the development of information, microelectronics and biotechnology, the emergence of microelectrode stimulation arrays for optic nerve stimulation has made vision restoration possible. As a prosthetic product, visual prosthetic devices can assist patients with partial recovery of acquired visual impairment to a certain extent. The implantability of visual prosthetic devices needs to ensure the miniaturization, safety and stability of the implanted devices. How to effectively provide energy for each functional module in the eyeball of the visual prosthesis device has become a problem that restricts the miniaturization and development of the artificial eyeball. Current research on visual prostheses focuses on image processing ...
