Description
Technical field
The present invention relates to a kind of functional electrostimulation devices.For to for example by central nervous system or peripheral nervous system
The limbs of dysfunction caused by lesion carry out functional electrostimulation.
Background technology
Cranial vascular disease, also known as apoplexy, are commonly called as cerebral apoplexy, have the characteristics that high incidence, high disability rate and high lethality
And there is significant threat to the mankind, cerebral apoplexy raised incidence year by year becomes and endangers killing for China or even world's human health
The patients with cerebral apoplexy of hand, about 70%-80% leaves sequelae, influences working and learning, there are disabled or even lifelong paralysiss by severe patient
Paralysis brings the huge pain of the duality of body ＆ mind.There are many method of limbs disturbance after clinical treatment apoplexy, wide
Such as trophic nerve drug therapy, physiotherapy, acupuncture and moxibustion therapy and the recovery function treatment of general application.In above-mentioned therapy, medicine
Object needs to be metabolized through liver kidney, and acupuncture causes pain, how to seek obtaining a kind of i.e. safety, and effectively, and painless noninvasive therapy, is
Our problems in the urgent need to address.
1961, Liberson et al. invented a kind of method, it is therefore an objective to stimulate calf using pedal-type switch control electric current
The respective muscle of innervation, and then ankle dorsal flexion is generated, patient's walking is helped, it is exactly functional electrotherapy to claim such method
Method.Ability formal definition in 1962 is FESfunctional electrical stimulation.FES belongs to neuromuscular electricity thorn
Swash neuromuscular electrical stimulation, one of method of NES, mechanism is to pass through low frequency pulse current
Reach certain range, stimulates the muscle of corresponding site according to a pre-set procedure, the muscle proper motion is induced, even if not
Proper motion can be reached, normal autokinetic movement can also be simulated, so as to improve muscle or muscle group function is stimulated.
Some researchers devise special stimulating system and implanted electrode for the patient of spinal cord injury, pass through surgery
Operation, is implanted into patient muscle tissue by electrode, can reach stimulation muscle and deep, but is likely to occur infection and operation merging
Disease, and implant system is expensive, and clinical expansion has difficulties, if can skin surface be placed in electrode, avoids performing the operation,
It can restore limb function by stimulating electrode, increase therapy safety and feasibility again.Nowadays new function electro photoluminescence
It should accumulate and give birth to, U.S. Patent application 10/278, in 575, inventor discloses the functional electrical stimulation system restored for wrist function
System.In U.S. Patent application 10/278,575, a kind of functional electrical stimulation of drop foot is disclosed.Much apply in stroke patients
Electro photoluminescence, in order to alleviate Flexor spasticity, often merely stimulation extensor.With biomimetic control technology, by brain-computer interface BCI and
The bionical FES control methods of central pattern generator (cpg) CPG are sent to CPG corresponding modes using BCI identification top level control orders,
Then FES is controlled, the technical device is advanced, has intelligence, but needs to connect with computer, therefore price is high, is unfavorable for facing
Bed is promoted.
In existing system, there are following defects：First, it cannot accomplish individuation, they can only receive preset
Program carries out electro photoluminescence, cannot control stimulus modality according to the case where itself；Secondly, simple to pierce to delay lissive musculus flexor
Swash based on extensor；Finally, it is connected with computer, there is intelligence, but expensive, it is complicated for operation, and inadaptable many education water
Flat relatively low medical worker and patient.
Invention content
The present invention is complicated for operation in order to solve existing electric stimulation, and can only receive preset program into
Row electro photoluminescence, lack can according to patient individual difference select electrical stimulus patterns functional electrostimulation device the problem of.Now carry
Replace electrical stimulation device for a kind of musculus flexor for treating paralysis and extensor.
It is a kind of for treat paralysis musculus flexor and extensor alternating electrical stimulation device, it include babinet, power switch, 6 lead to
Track selector, 6 channels, counter, power supply, signal control device and n electrode, n ＞ 2,
N electrode, musculus flexor and extensor for being individually placed to human body apply electro photoluminescence to musculus flexor and extensor,
6 channel to channel adapters and counter are embedded in the upper surface of babinet, and power supply and signal control device are respectively positioned on babinet
Inside, 6 channels are the aperture that the upper surface of babinet opens up,
The side of babinet is equipped with power switch, and power switch connects the power supply signal input of power supply,
Power supply provides electric energy needed for electro photoluminescence for external input power to be converted into DC power supply to n electrode,
The lower end of each channel to channel adapter is correspondingly arranged there are one channel,
6 channel to channel adapters are all connected with the channel selecting signal input terminal of signal control device, counter connection signal control
The control signal output of the count signal input terminal of device processed, signal control device passes through the conducting wire connection electrode on channel
Control signal input,
Each channel to channel adapter, electrode for selecting electric energy to be applied and selects corresponding signal mode to the electrode
Formula,
Counter, for increasing the working time for either reducing signal mode and increase or reducing under the pattern,
Signal control device, the different mode for being selected according to each channel to channel adapter, the electric energy from power supply is applied
It adds on the electrode selected with the channel to channel adapter.
Beneficial effects of the present invention：It turns on the power switch, by the beginning button on lower box, electrode is placed on bending for human body
On flesh and extensor, the channel to channel adapter that the electrode is correspondingly connected with then is rotated, a kind of selector operating mode in selector channel makes to lead to
Track selector works, and can add and subtract pattern by counter or add and subtract the working time under the pattern, uses the system can be with
The pattern of electro photoluminescence and the working time of electro photoluminescence are voluntarily adjusted according to their needs.The system features in convenient, painless, nothing
Wound lives for extremity motor function after alleviating hemiplegic patient's spasm, pain, improving apoplexy and activity of daily living, expansion joint
Dynamic degree etc. has significant curative effect.The present invention can be directed to individual difference and select suitable stimulation mode, pass through the frequency of setting
Rate stimulates muscle, induces muscle as autokinetic movement or simulation autokinetic movement are done in electro photoluminescence, is finally reached improvement or restores muscle
The purpose of function.
