Real-time feedback intelligent electrical stimulation device and stimulation method thereof

Abstract

The invention discloses a real-time feedback intelligent electrical stimulation device and a stimulation method thereof. The real-time feedback intelligent electrical stimulation device comprises a human body contact device and the like, wherein the human body contact device, a myoelectricity collector, a stimulation outputting device and a micro processor are all connected with a channel selection switch, the myoelectricity collector and the stimulation outputting device are both connected with the micro processor, the human body contact device is an electrode device integrating stimulation outputting with myoelectricity collecting in the same channel, the channel selection switch is used for switching the work state of the human body contact device between the myoelectricity collector and the stimulation outputting device, the myoelectricity collector collects and processes human body myoelectricity signals, the stimulation outputting device generates stimulation pulse output, and the micro processor is used for carrying out A/D conversion on the myoelectricity signals of the myoelectricity collector and controlling stimulation waveform of the stimulation outputting device. According to the real-time feedback intelligent electrical stimulation device and the stimulation method thereof, stimulation and collection are simultaneously carried out in the macro level, subjective motion wills and requirements of patients are reflected completely in real time, and accordingly the patients are helped to finish motions which the patients want to carry out.

Description

technical field [0001] The invention belongs to the field of medical devices, in particular to a real-time feedback intelligent electrical stimulation device and a stimulation method thereof. Background technique [0002] The development of neuromuscular electrical stimulation technology has gone through the following three stages of development: [0003] The first generation of electrical stimulation technology: open-loop electrical stimulation, that is, the electrical stimulator stimulates the patient for a certain period of time according to the stimulation parameters (stimulation intensity, frequency, pulse width, etc.) set by the therapist in advance. This stimulation method only achieves a pure therapeutic effect on the neuromuscular, and has a positive effect on the maintenance of muscle structure and function. However, during the treatment process, the patient only accepts the treatment passively, and the interaction between the patient and the device cannot be real...

AI Technical Summary

Problems solved by technology

[0005] However, due to technical reasons, there is a shortcoming in the existing EMG-triggered electrical stimulation equipment: when the electrical stimulation is performed, the equipment is in a stimulating state, and at this time, the acquisition of EMG signals is not performed.

One drawback of the established feedback is that the stimulation and EMG acquisition cannot be performed simultaneously

In addition, the issuance of electrical stimulation only reflects the amplitude of the EMG signal reaching the threshold, and the actual stimulation intensity cannot be adjusted according to the EMG signal intensity of the actual patient.
