Embodiment Construction

[0049] Below in conjunction with accompanying drawing, introduce the content of the present invention in detail.

[0050] Such as Figure 5 As shown, the most basic architecture of the vibration type somatosensory evoked potential stimulation system of the present invention can adopt the LPC700 series OTP single-chip microcomputer P87LPC769 that PHILIPS Company releases in the present embodiment, or the ADuCxxx series single-chip that American AD Company releases Microcomputer, a single-chip microcomputer synthesizes corresponding pulse signals with adjustable frequency and duty cycle through internal operations. The single-chip microcomputer described in this device includes three important input / output interfaces: D / A interface, A / D interface and T / R interface. Among them, the D / A interface is connected with the pulse shaping circuit, and its function is to convert the control information in the form of digital signal into an analog signal form, and send the obtained analog...

Abstract

The body sensation induced potential stimulation system based on vibration includes monolithic microcomputer, pulse shaping circuit, power amplifier circuit, state display, body sensation stimulation generator, and fixer. The monolithic microcomputer calculates to synthesize pulse drive signal with specific frequency and adjustable duty ratio, so that the body sensation stimulation system generates vibration waveform with envelope simulating true touch sensation, vibration sensation and pain sensation to reach the aim of effective body sensation stimulation. The present invention controls the generation of body sensation stimulation signal simulating touch sensation, vibration sensation and pain sensation, and may be used in the application research of body sensation induced potential SEP. The present invention has the features of high integration degree, adjustable strength, high performance/cost ratio, etc. and may be widely applied.

Description

technical field [0001] The invention relates to a somatosensory evoked potential stimulation system, in particular to a vibrating somatosensory evoked potential stimulation system meeting the needs of somatosensory evoked potential research. Background technique [0002] As an important sensory organ of human beings, the skin is a very sensitive receptor with very dense contacts, and the resolution of contacts varies in different parts of the body. Humans can obtain two basic sensations through contact or touch (including vibration, touch, pain, etc.): somatosensory and proprioceptive. Somatoception provides us with information about object shape, surface texture or roughness, and temperature; proprioception is the internal force and movement of muscles felt by muscles and tendons, thereby obtaining in-depth information about object shape, strength, and hardness. The skin is a special sensory organ whose role and efficacy cannot be replaced by other functional organs. [0...
