It is that conduct to electrode 22a and provide via the skin of target body site one low strong that signal is irritated caused by circuit 21a processed
Degree underlying nerve irritates.Underlying nerve be therefore obtain temporary paralysis and drop is quick, and thus alleviating neuropathic pain.
It is noted that " irritating signal " this word used herein above is about an electric signal, it includes can allow electrode 22a
Generate the voltage signal or current signal of an electric field.Unless the pattern of the electric signal especially provided in the claims, not so makees
It is not the range to limit scope of the claims to irritate the pattern of the electric signal of signal.
Irritating signal is the nerve conduction to stop underlying nerve.For example, if irritating signal as voltage letter
Number, then the range of signal is irritated between -10V and -1V or between 1V and 10V.If irritating signal is a current signal, then
The range of signal is irritated between 2mA and 50mA.For example, irritating signal is the voltage signal or perverse that value is 5V
Energizing signal is a current signal, can be the current signal of a 20mA.
In view of nerve drop sensor is used for the example of median nerve (median nerves), any adjacent two
The distance between a electrode 22a be between 5mm and 60mm, the distance between each electrode 22 and underlying nerve be located at 0 with
Between 20mm, the width of two electrode 22a is between 2mm and 20m, and so when generating electric field, electric field is at least partly to cover
Lid conducts the underlying nerve of pain and its value is between 100V/m and 1000V/m, and wherein underlying nerve is to be located at spinal cord
On nerve conduction path between pain spot.
When application irritates signal to underlying nerve, irritate signal frequency can between 200KHz and 450KHz or
Between 450KHz and 550KHz or between 550KHz and 800KHz, underlying nerve is temporarily by desensitization and its nerve
Pain may be mitigated.If selected frequency between 200KHz and 450KHz, then device operates in rather low-frequency, because
And the risk for generating biological heat be it is less, can reach cell safety.Another side, if selected frequency be located at 550KHz with
Between 1000KHz, then generated electric field is that have biggish density, thus electrical stimulation can have preferable performance.
It is the schematic diagram to irritate the waveform of signal in addition, please referring to Fig. 7.In the present embodiment, sensitive from nerve drop
What device exported, which irritates signal, to irritate signal for the one of a continuous string wave, a continuous triangle wave or high-frequency impulse.In this implementation
Example in, irritate signal be for a continuous string wave and its value be between+3.5V and -3.5V, and its frequency be for
500KHz(1/Ts).One pulse cycle time TpIt is that there are multiple pulse signals and at least one section of time of having a rest (Tp-Td).One
Pulse cycle time TpIt is the inverse of pulse recurrence frequency.Pulse recurrence frequency (also referred to as pulse frequency, PRF) be for 0~
1KHz or preferably 1~100Hz.In the present embodiment, the pulse recurrence frequency for irritating signal is about 2Hz.In addition, one
The duration T of pulse in pulse cycle timedIt is for 1~250ms or preferably 10~100ms.In the present embodiment,
It is for 25ms.By adjusting an operation duration Td, the amount of electrical stimulation is to be adjusted, and dissipate generated biological heat
Time be also adjusted accordingly.For example, if to irritate intensity relatively low, then duration TdIt can be increased with continuous
It irritates.If it is all relatively high with frequency to irritate intensity, then duration TdIt can be reduced to increase the time of dissipation.
In other words, under the action of low-intensity, low temperature and high frequency irritate signal, electric field is covering underlying nerve and its surrounding
Region, while the nerve cell of underlying nerve will not be destroyed, inhibit the biomolecule hyperplasia as caused by underlying nerve whereby.Such as
This, can be lowered in the neurotransmission ability of the underlying nerve of target area and neurotransmission can be blocked.
By following experimental example, the operation and effect of electrical stimulation device can be explained, electrical stimulation device is to irritate dorsal root ganglion
(dorsal root ganglion).However, following experimental example by way of example only rather than limit the utility model range.
Experimental example: to the pressurization model (compression model) of rat median nerve (median nerve)
It is heavy using SD rat (Sprague-Dawley rats, BioLASCO, Taiwan co., Ltd., Taiwan)
About 250-300 grams.The committee is all looked after by the experimental animal of Taiwan Univ. and used to all programs and step
(Institutional Animal Care and Use Committee of Taiwan University) is allowed.PE-
90 hoses are surgically to be wrapped in the median nerve of the left front pawl of SD rat, and then PE-90 hose is pinioned to press
Urgent median nerve, which is used, makes the fore paw of SD rat generate pain.In this experimental example, the right fore paw of rat is considered to be control group
(N=10) and the left front pawl of rat is for experimental group (N=10).After the procedure, it is pressurizeed with checking within rat observed 14 days
Whether the development of model is stable.As shown in figure 8, the effect of the pressurization model of experimental group, the i.e. pain of the left front pawl of SD rat, are
Quickly increase after operation (BL), is then become stable after second day (D2) of observation.
After development stability two weeks of pressurization model, high frequency electrical stimulation treatment is implemented in experimental group.High-frequency electrical
Irritate treatment carry out be by apply with 500KHz pulse frequency and 5V value a PRF signal in the rat of experimental group
On the skin of fore paw, and 5 minutes by a definite date.As a result, being shown in Fig. 9.Relaxing for pain is slow substantially quite quick.Such as Fig. 9 institute
Show, (D1) every other day after the treatment, Pain behaviour (degree) and the control group of experimental group are similar.After D1, experiment
The Pain behaviour (degree) of group started slowly decline, in decline in next two weeks only 30%.This is demonstrated even if only 5
The treatment of minute, electrical stimulation provided by the utility model also reduce feeling (desensibilization) almost two weeks as long as of pain.
