Multi-node electrical stimulation system and method

Abstract

The invention relates to a multi-node electrical stimulation system and method. The system comprises a sending end and multiple electrical stimulation nodes worn on the parts, needing to be stimulated, of a human body. The sending end couples modulation electrical signals carrying node serial numbers and stimulation waveform parameters to human body communication channels through a sending electrode of the sending end according to the conduction characteristics of human body tissue. An integrated electrode of the electrical stimulation nodes is used for receiving the modulation electrical signals transmitted to the surface of the human body through the human body communication channels. The modulation electrical signals are processed through signal conditioning and demodulating, corresponding waveforms are selected through a microcontroller, corresponding electrical stimulation waveforms are output through the integrated electrode after boosting, and the corresponding parts of the human body are stimulated. The system is used for rehabilitation training of a patient with paralytic limbs caused by the reasons such as central nerve damage, the system carries out electrical stimulation on the corresponding parts of the limbs according to the transmission paths of electroneurographic signals when the limbs move, and therefore the rehabilitation of the moving function of the limbs of the patient is promoted.

Description

technical field [0001] The invention relates to a multi-node electrical stimulation system and method. Background technique [0002] The state of the existing disclosed technology: the patent (application number 201210051592.0) provides a multifunctional muscle electric stimulator for treating partial denervation and complete denervation. The stimulator only electrically stimulates a single site at a time. Patent (Application No. 200910068111.5) designed an electroacupuncture and electrical stimulation therapy device that can output a variety of waveforms. Basic electroacupuncture, electrostimulation, and specific prescription electroacupuncture or electrostimulation are used in combination. The patent (application number 200810070307.3) designed an implantable multi-channel nerve electrical stimulation transmission device based on a microcoil array, which sends control signals to the electrical stimulator through the transmitting coil.

Problems solved by technology

[0003] Problems and defects in the existing technology: Most of the existing electrical stimulators can only achieve single-channel or single-node electrical stimulation

However, in many cases, the electrical stimulation of a single node is difficult to achieve a good therapeutic effect.

For example, after a stroke, the brain loses control over the hemiplegic limb, resulting in dysfunction of multiple joints and muscle groups in the limb. At this time, if only a single part is electrically stimulated, it is difficult to recover the motor function of the limb.

In addition, many existing electrical stimulation systems use wired connections, which restricts patients' basic daily activities.

However, the coordinated control of multi-channel electrical stimulation nodes through common wireless methods has problems such as large power consumption and cumbersome pairing steps.
