Embodiment Construction

[0021] The embodiments of the present invention are described in detail below in conjunction with the accompanying drawings: this embodiment is implemented on the premise of the technical solution of the present invention, and detailed implementation methods and specific operating procedures are provided, but the protection scope of the present invention is not limited to the following the described embodiment.

[0022] like figure 1 As shown, this embodiment includes an image acquisition unit, an image processing unit, a stimulator and a stimulation electrode array. Among them, the image acquisition unit obtains the image information, and transmits the information to the image processing unit, and the image processing unit processes the image information, encodes it into an electrical signal, and then transmits it to the stimulator to generate electrical stimulation pulses, and then acts on the skin through the electrode array. receptors.

[0023] like figure 2 As shown, ...

Abstract

Disclosed is a touch-visual substitution system based on the electric stimulation, which belongs to the medical device technical field. In the invention, the acquired character and image information is transmitted to an image processing unit by an image acquisition unit; the image processing unit processes the image information pre-correction towards the acquired image, improves the image quality and then carries out the image information simplification, enhancement, encoding processing, so as to enable the image information to be converted into an electrical signal for a stimulator; the stimulator is controlled to generate multi-channel stimulation pulses with certain requirements according to the stimulation information; a stimulation electrode array acts on the human body skin to generate touch sense, and the stimulator provides certain adjusting function for users.

Description

technical field [0001] The invention relates to a system in the technical field of medical equipment, in particular to a touch-vision substitution system based on electrical stimulation. Background technique [0002] Along with my country's economic development and social progress, blind people have continuously increased requirements for improving their lives and quality of life. Brain plasticity theory and sensory replacement theory bring hope to the rehabilitation project of visually impaired people: various senses of the human body, such as vision, touch, hearing, etc., can be replaced by each other. That is, when the main sensory input channel is obstructed, the neurons in the cortex of the impaired sensory channel also respond to the information input from other sensory channels, so other sensory channels can be used to replace the damaged sensory channel to input information to the brain, thereby providing Some degree of functional recovery. On the basis of the abov...
