Problems solved by technology

However, this method assumes that the patient’s daily life is very regular and lacks flexibility. If the patient gets up in the middle of the night to go to the toilet or wake up for some reason, and the pacemaker is turned off, it will bring unexpected troubles to the patient.

Embodiment Construction

[0043] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0044] refer to figure 1, the feedback type implanted nerve electrical stimulation system of the present invention mainly includes a pulse generator 1 implanted in the body, an electrode 3, and a control device located outside the body. The pulse generator 1 is electrically connected to the electrode 3, so that the pulse generated by the pulse generator 1 is transmitted to the electrode 3, so as to electrically stimulate the nerve target to achieve a therapeutic effect. The electrode 3 has multiple pairs of contacts, for example, 4 pairs, and one or more pairs of electrode contacts can be selected as input or output by the electrode selection control unit 4 .

[0045] refer to figure 2 , a feedback electrical nerve stimulation system, such as an implanted deep brain electrical stimulation system, an implanted cortical electrical stimulation system, an implanted spi...

Abstract

The invention discloses a feedback type nervous electrical stimulation system and a feedback control method thereof. An implanted electrode is employed as a signal acquisition unit. An acquired nervous electrical input signal goes through an electrode switching control unit, a signal conditioning unit, an A / D converter, a signal processing unit, an output control unit in order, and enters into an electrode selection control unit to form a feedback loop. When the signal processing unit determines that a user is in a deep sleep state, the output control unit automatically weakens or stops an output pulse signal of a pulse generator. Otherwise, the output control unit maintains or automatically recovers a conventional output pulse signal of the pulse generator. Compared with the prior art, without increasing extra perception parts and without artificial intervention, automatic output adjusting on demand is realized, wasted power consumption of stimulation which could be fully stopped because of symptom alleviation or elimination of a patient like a dyskinetic disease at deep night sleep is reduced, thus a service life of the nervous electrical stimulation system is substantially prolonged.

Description

technical field [0001] The invention relates to an implanted nerve electrical stimulation system, in particular to a feedback type nerve electrical stimulation system capable of automatically adjusting output on demand and a feedback control method thereof. Background technique [0002] Electrical nerve stimulation plays an important role in the treatment of nerve dysfunction and rehabilitation of nerve injury. The implantable nerve electrical stimulation system releases high-frequency electrical stimulation by implanting electrodes at specific nerves such as motor nerves and sensory nerves in the human body to stimulate specific nerves, thereby restoring the body's functions to normal operation. [0003] At present, implantable neural electrical stimulation systems mainly include implantable deep brain stimulation (DBS, commonly known as brain pacemaker) for the treatment of typical movement disorder diseases such as Parkinson's disease, implantable cerebral cortical stimul...
