Multifunctional nervous system electrical stimulator for treating words swallowing disease

Abstract

The invention relates to a medical device, in particular to a nervous system electric stimulator for multifunctional swallowing and speech therapy. It includes a power management unit, a microprocessor, and a touch screen unit, and is characterized in that it also includes an electric therapy unit, a magnetic therapy unit, a music therapy unit and a feedback signal unit, all of which are connected to the microprocessor. The electrotherapy unit includes an electrotherapy single-chip microcomputer, a signal generator, a signal processing circuit, a modulation module, a constant current source module, and stimulating electrodes, and the magnetic therapy unit includes a magnetic therapy single-chip microcomputer, a magnetic field generator, and a magnetic therapy pole , the magnetic field generator is composed of a plurality of copper coils, and a magnetic silicon steel sheet is arranged in the middle of each copper coil. The invention uses specific current to stimulate the human body, and then detects their thresholds according to the feedback signal, then automatically selects the treatment means electricity and magnetism, and adopts a unique modulation current technology to effectively separate the treatment threshold and the pain threshold, which has body adaptability and can Tonality, outstanding curative effect and other advantages.

Description

technical field [0001] The invention relates to a medical device, in particular to a multifunctional nervous system electrical stimulator for helping patients with functional disorders caused by nervous system diseases, especially cerebrovascular diseases, to recover. Background technique [0002] Nervous system diseases, especially cerebrovascular diseases, are common diseases in my country. The well-known electrical stimulation equipment utilizes treatment techniques such as periodic function waveforms and waveform direct amplification output to stimulate local brains, which can increase ischemia and improve local blood flow. Improve blood circulation in the brain, prevent secondary and delayed damage to neurons in the ischemic penumbra, and reduce the infarct size. However, currently known electrical stimulation instruments generally cannot modulate the output current or the modulation method has many defects, and cannot separate the treatment threshold from the pain thres...

Problems solved by technology

However, this kind of neurorehabilitation treatment based on biofeedback is still limited to electrical stimulation therapy, and the method is single, and electromagnetic dual therapy cannot be performed, nor can magnetic therapy or electrotherapy be automatically selected according to the feedback signal.
