Embodiment Construction

[0023] The present invention will be further described below in conjunction with the drawings.

[0024] Such as figure 1 As shown, the feedback type animal nerve electrical stimulation device 4 is connected to the implanted electrode connection terminal 2 of the recipient animal brain area to be stimulated in the recipient animal’s brain 1 through the connection line 3, and the feedback type animal nerve electrical stimulation device 4 communicates via wireless communication. The link establishes a connection with the wireless console 5 for data communication.

[0025] Such as figure 2 , 3 As shown, a feedback type animal nerve electrical stimulation device includes a main control module, a multi-channel stimulation pulse generation module, a connection module, a wireless communication module, a motion posture capture module, a calendar clock module, and a power management module. The multi-channel stimulation The pulse generation module also includes a stimulation current generat...

Abstract

The invention relates to an electrical stimulation device and concretely relates to a feedback animal nerve electrical stimulation device comprising a master control module, a multi-channel stimulation pulse generation module, a connection module, a wireless communication module, a motion posture capture module, a calendar clock module and a power management module. The multi-channel stimulation pulse generation module further includes a multi-channel isolation unit that stimulates a current generation unit and is connected to the current generation unit. According to the feedback animal nerveelectrical stimulation device, the motion state information of a recipient animal is obtained by using the motion posture capture module so as to conveniently provide feedback information for the closed loop control of the electrical stimulation device. In addition, according to the device, the electrical stimulation currents of multiple channels are isolated from each other and effective electrical stimulation can be performed without mutual interference, and electrical stimulation parameters can be adjusted according to the working time of the electrical stimulation device to overcome the influence of the growth of surrounding physiological tissues after the implantation of an electrode in the head of the recipient animal on a current stimulation effect.

Description

Technical field [0001] The invention relates to an electrical stimulation device, more specifically, to a feedback type animal nerve electrical stimulation device. Background technique [0002] The animal's motor behavior is controlled by neurons in a specific area of ​​the brain. The neuron firing in the corresponding region can control the animal's motor behavior. Therefore, adjusting the neuron firing in the corresponding region with an appropriate stimulation method can control the animal's motor behavior. The current electrical nerve stimulators are divided into two main types of stimulation sources: constant voltage source stimulation and constant current source stimulation. The advantage of constant pressure source stimulation is that the voltage can be applied to the nerve tissue in time, which can ensure the rapid stimulation. However, because the animal nerve tissue is a combination of impedance and capacitive reactance, the effect of constant pressure stimulation will ...
