Description
Technical field
What the present invention relates to is a kind of system of medical assistance technical field, specifically is that active Worn type auxiliary electrical stimulating system is pointed in a kind of accurate control.
Background technology
The World Health Organization (WHO) statistics whole world has 1324.37 ten thousand people to suffer from diseases of spinal cord, and just there is the newly-increased spinal cord injury case of 11000 examples every year in the U.S., and according to another incomplete statistics, all kinds of spinal cord injury patients in China's Mainland have reached 1,100,000 people.This numeral also has ascendant trend day by day.After the spinal cord injury, though paralytic's muscle still has contractile function, owing to the nervous pathway between brain and muscle is cut off the autonomic movement ability of losing.Except diseases of spinal cord, apoplexy nervous system disease such as (apoplexy) has also produced a large amount of paralytics.On the market in paralytic's the motion aid system, comparatively popular electric stimulation therapeutic apparatus is to utilize artificial weak current pulse signal to stimulate paralytic's skeletal muscle at present, thereby makes patient's skeletal muscle produce contraction, makes limbs produce the motion of expectation.But present surface electrical stimulation system can only stimulate bulk muscle, basic coarse action such as realize that upper limb bends and stretches, grasping and lower limb are walked, stood.The muscle of being responsible for finger motion control in the human body is more very thin, arranges closely, so also fail to realize to pointing active accurate artificial electrical stimulation control.But motion particular importance for patient of finger can be proceeded meticulous activity (as writing, typewrite, do gesture, shoegaze etc.) if hope the patient, just need accurately control interphalangeal joint and relevant muscle group.In addition, because the difference of patient's build, the patch location of electricity irritation is difficult to confirm, all need carry out individual setting for each patient.The present invention will address the above problem.
Along with scientific and technological progress, a lot of countries and company have developed the commercial product based on functional electric stimulation.Like NESSH200 Hand Rehabilitation System.But,, also do not realize for the accurate control of finger, and function is comparatively single, can't make the finger activity reach due motility although this system can help patient to hold actions such as pawl, palm stir.
Through existing literature search is found; Prior function property electricity irritation aid system is selected for use basically all is that the electrode patch of large-size is controlled; Thereby control accuracy is restricted, and single fixed electrical stimulation pattern also make correlation function expand.
Summary of the invention
The present invention is directed to the above-mentioned deficiency that exists in the prior art, provide a kind of accurate control to point active Worn type auxiliary electrical stimulating system.。The present invention realizes the accurate control of paralytic to finger through more meticulous stimulus modelity is provided, thereby helps patient under the training that does not have the Physical Therapist, can make the motion independently of each finger.
The present invention realizes through following technical scheme:
Active Worn type auxiliary electrical stimulating system is pointed in a kind of accurate control, it is characterized in that, comprises electric stimulation pulse output device and Worn type structure, and wherein, the electric stimulation pulse output device is connected with the Worn type structure;
-electric stimulation pulse output device receives the instruction input of control side and produces the respective electrical boost pulse;
-Worn type structure links to each other with skin of forearm and exports electric stimulation pulse control Skeletal Muscle Contraction.
Said electric stimulation pulse output device comprises: command receiver, controller and electrostimulator; Wherein, Command receiver is connected with controller and carries action command; Controller is connected with electrostimulator and transmits electrical stimulation pattern information, and electrostimulator is connected with the Worn type structure and transmits electric stimulation pulse.
Said action command and electrical stimulation pattern information have corresponding relation;
Said corresponding relation is: after controller is analyzed action command; Choose simultaneously some to the Worn type structure electrode patch and adjust the input electric stimulation pulse characteristic of each counter electrode paster; Control flexor digitorum profundus, flexor digitorum superficialis, extensor digitorum crowd's contraction and the angle of bend of each interphalangeal joint of forearm relatively independently, thereby control the movable or concrete gesture of each finger.
Said Worn type structure comprises: some counter electrode pasters and special fixedly bandage, wherein, electrode patch is connected with the electrostimulator of special fixedly bandage and electric stimulation pulse output device respectively.
Said Worn type structure also comprises the electrode double buckle, and said electrode patch is fixedly connected with special fixedly bandage through the electrode double buckle.
Said special fixedly bandage is two, is positioned over the near-end and the far-end of forearm respectively, as the positive and negative electrode bandage.
Said electrode patch is reusable gel electrode paster.
Said gel electrode paster specification is 20mm * 35mm.
And comparing with prior art; The invention has the beneficial effects as follows: the control accuracy that has improved electric stimulation pulse; Not only can realize also can carrying out the control of elaborate to the finger interphalangeal joint through the stimulation of large tracts of land muscle group being carried out rough expectation action control.Helped flexible control and the use of paralytic greatly, can carry out, for example write, shoegaze and gesture etc. the finger flexibility ratio correlated activation of having relatively high expectations to its finger.Can keep simultaneously the finger muscle group vigor of patient's different depth, prevent amyotrophy, reduce spasm, make patient's rehabilitation efficacy even more ideal.In addition, the particular design of Worn type structure and dismountable electrode patch also makes the present invention adjust simply and easily, thereby the patient who is fit to different builds dresses.
