Description

A kind of Magnetotherapeutic apparatus for backbone reduction system

Technical field

The application is related to spine recovering field, and in particular to a kind of convalescence device of backbone and muscle.

Background technology

Modern is because seat works, bad life habits and disease or certain reason cause body a part to be chronically at Anchor, muscle is chronically at the state of underload contracts last.This can cause moisture in the fibr tissue matrix such as ligament to subtract Few, viscoelasticity weakens, interfibrous lubrication reduction.Meanwhile, interfibrous hypotelorism, the extension of contact phase, this may lead Cause to produce chemical horizontal key between fiber, so as to stick together between causing fiber.And such crowd is often because of the chronic inflammation of muscular tissue Disease and the fiber for causing new life, these newborn fiber alignments are disorderly, form adhesion again with original fiber, further limit fibre Slip between dimension.Long it, this " vicious circle " will cause muscle to occur slight contracture, cause muscle tonue.The life of modern Mode living determines that such muscle tonue is mostly occurred on backbone attachment or sizes related muscle group, and long will cause backbone tired The appearance of labor, overload or even irreversible damage.

Implementing spinal traction, fixation simultaneously by applying the alleviation muscle tonue quilt such as machinery, electric field in spine recovering field It is proved to be effective treatment means.But the unnecessary damage of backbone is inevitably caused during being somebody's turn to do, or even meeting (spinal cord injury, SCI) is damaged to spinal cord, and medical personnel often is reluctant to adopt in order to avoid the damage With positive therapeutic scheme.Also often occurs unexpected massage damage in the massage processes that non-spinal is damaged simultaneously.So When being related to spinal treatments, needs provide effectively real-time electrophysiologic monitoring means.How electro physiology to be detected and a variety of backbone health It is a direction that this area has much development prospect that multiple means, which combine,.Obtained in numerous electrophysiological indexs effectively and have generation The data of table, and with the follow-up spine recovering of guidance progress, be also this area research emphasis.

Neuro electromyograph is, according to Nervous System Anatomy principle, to be stimulated by the energy of diversified forms, to organism The biological electricity that peripheral nerve is produced and the technology that the electrical characteristics of organism are measured, record and analyzed.Evoked ptential (evoked Potentials, EPs), refer to that giving nervous system (from receptor to cerebral cortex) specifically stimulates (sound, light or body-sensing thorn Swash), or brain is processed the information for stimulating (positivity or negativity), produce and can examine in the corresponding site of the system and brain It is going out, have with stimulation be relatively fixed time interval (relation during lock) and certain bits phase biological electricity reaction.It reflects cynapse biography Pass, axon conduction cell and molecular system structure and function integrality, be a kind of effective its functional attributes.

Electromyographic signal (EMG) is a kind of bioelectrical signals produced with muscular movement.In the limb motion of people, greatly The neuronal excitation of moving region is controlled in cortex and the electric pulse of certain frequency is produced, this electric pulse passes through nervous system Specific meat fiber is accurately conducted, when these electric pulses reach neural muscle cynapse, soleplate is produced in muscle fibre Current potential, its depolarising will produce a series of movements current potential in muscle fibre, cause contraction of muscle, limbs is completed set by brain Action.Surface EMG is the synthesis physiology electrical phenomena that each several part muscle activity is generated in limb motion, and surface EMG is divided Analysis research can find its corresponding relation between muscle physiological state and limb motion patterns, can be widely applied to clinical doctor The numerous areas such as, sports medical science, medical rehabilitation.In human skeletal muscle, there is Severe Pain point in muscle muscle tonue band The viewpoint of (myofascial trigger point, MTrP) is widely recognized as.It can be recorded in the MTrP areas of muscle tonue band To spontaneous electrical activity, further, muscular tone can also be showed and is detected in the form of myoelectricity.Flesh in simple terms Meat makes expression by electricity physiological signal to its physiological status (stressing myotonic physiological status in the present invention to state)；In turn Appropriate regulation can also be made to muscle tonue by way of impressed field influences myoelectricity.

Exist in the prior art by carrying out electro photoluminescence to patient and receiving myoelectricity/biofeedback signals of patient, so that Reaching improves the method and apparatus of muscular tone.But these devices use simple electrode stimulating, frequency be located substantially at 5Hz~ Between 100Hz, electric signal is simple comprising waveform.It is single to the effect of stimulation of human body, be easily caused peripheral nerve fatigue and production Raw a large amount of unnecessary electrode heat.Insertion electrode or patch electrode may then cause skin keratin lesion and bring unnecessary damage Wound.Patient can produce the unnecessary imagination for visible electrode stimulating directly perceived, and such a psychology also results in therapeutic effect deterioration. Above all peripheral nerve may react good for short-term stimulation, but long-term treatment can cause neural fatigue, and effect also can It is plummeted.Reason is in evolutionary process that human nerve stress reflect for the injury that environmental stimuli is produced and have one to adapt to Journey.And the human body self neural electricity including neuromere is then less prone to such fatigue, its fatigue endurance phase is longer in other words.

Neuromere be function identical neuron cell body beyond the maincenter around position set nodositas structure Make.Its surface is surrounded by one layer of connective tissue membrane, wherein containing blood vessel, nerve and fat cell.Envelope and perineural outer membrane, god Connected together through beam film, and go deep into the network in neuromere in formation neuromere.The fiber that nerve cell is sent in section The relevant part of body is distributed to, claims postganglionic fibers.By physiology and the difference of form, neuromere can be spinal ganglion (sensibility god Warp knuckle) and the class of automatic ganglia two.Cerebrospinal ganglion functionally belongs to sensory neuron, morphologically belong to false monopole or Bipolar neuron.Automatic ganglia includes sympathetic and parasympathetic ganglion.Sympathetic ganglion is located at backbone both sides.Parasympathetic god Warp knuckle is located in the vicinity of institute's dominating organs or organ walls.In neuromere, aixs cylinder and the postganglionic neuron group of preganglionic neuron Into cynapse.Neuromere is associated by nerve fibre with brain, spinal cord.

The physiology that inventor is carried out by laboratory, which is tested, to be found：By stimulating the nervous system including neuromere to lead The biological electricity for causing human body to produce is inaccurate controllable in amplitude, frequency, and the biological electricity helps lend some impetus to nerve and controls muscle, knot Form tissue with having the rhythm and pace of moving things diastole, contraction and the blood circulation of tip fine vascular.It will also be led for ganglionic stimulation simultaneously Effect of the ascending nerve fiber to brain is caused, there is reduction of patient anxiety, anxiety in practice, it is tight for flesh caused by nerve Opening has certain therapeutic effect.But situation about being interfered with electrocardiosignal inevitably occurs during Neural stem cell, Above-mentioned interference can also be improved by the way of electrocardio triggering magnetic stimulation circuit while being shielded, this is also this area skill Art personnel are difficult to technical problem urgently to be resolved hurrily.Meanwhile, it is how easy quick and non-invasively stimulation sites are accurately positioned It is then the problem that those skilled in the art do not overcome.Conventional physiotherapy practitioner is pressed often through experience and patient feedback enters Row positioning is so both inaccurate to cause accidental injury；Certainly also it has been proposed that being measured by setting up electrode, still Laboratory environment and clinic differ greatly, and testing cost is high to require very high simultaneously for operator.

The content of the invention

The present invention provide it is a kind of damaged for patient spine, backbone fatigue and related muscle group anxiety are alleviated, treatment it is whole Complex system.The shortcoming of single spinal problems, comprehensive a variety for the treatment of means, default can only be directed to by which overcoming conventional reduction device Intelligent therapeutic is realized under the monitoring of detection program.Simultaneously as that may be present a variety of pathogenic in view of the same presentation of user Mechanism, the detection being combined using a variety of detection means, decision logic are allowed the devices to voluntarily according to the specific feelings of user Condition makes appropriate physiotherapy.So as to realize effective, safe backbone reduction, rehabilitation, it is to avoid unnecessary secondary damage or delay.

The reduction device that the present invention is referred to include checking with EMG method module 1, magnetic therapy module 2, supporting module 3, control module 4, Display module 5 and electrocardio module 6 etc..

The present invention relates to electro physiology and electromagnetism medical domain.Myoelectricity (EMG) signal known to us, its amplitude, frequency spectrum With own characteristic：The surface EMG signal measured from body surface is generally very faint, and amplitude is usually no more than 5mV；Frequency also compares Relatively low, spectral range is generally 0.02 1 1000Hz, and spectrum energy is concentrated mainly between 0.25~350Hz.The relaxation of muscle There is good linear relationship between tensity and generation surface myoelectric voltage amplitude.Myoelectricity voltage magnitude is measured to use Root method, can both reflect the variation characteristic of EMG signal amplitude on time dimension, and muscle load sexual factor and flesh are depended on again Inner link between meat physiology in itself, biochemical process, therefore, the time-domain analysis index be commonly used in real time, not damaged Ground reflects muscle activity state, with preferable real-time.Meanwhile, the impedance of human muscle part can effectively state human body and put Loose degree, in general human body more loosen, impedance is smaller.Therefore combine using the above method can in real time, obtain human body exactly Muscular tone degree, and it is classified.

Obtained muscle tonue degree may include much information, for example bone injury, lactic acid caused by backbone strain, hyperplasia etc. Pain caused by metabolism disorder and muscle cramp, and muscular tone etc. caused by external force or psychology.If can not have Effect differentiation causes myotonic different reasons, then can not effectively carry out immunotherapy targeted autoantibody.The present invention is by body surface specific region Set electromyographic signal acquisition device obtain the real-time myoelectricity of human body, impedance signal, while by can real-time live program gate control logic Preset program in circuit realizes identification and classification for the abnormal inducement of above-mentioned electromyographic signal, and according to different judged results To carry out the combination of different treatment means.

First, transcranial magnetic stimulation (TMS) first is implemented to user, selectes stimulated zone and be located at Epidural cavity, lured by magnetic field Send out potentiometric detection.Simple magnetic stimulator is by dc source, charging circuit, energy-storage travelling wave tube, discharge switch, charge-discharge control circuit With a few parts such as coil composition.Various transcranial magnetic stimulation instruments well known to those skilled in the art and the control dress including software Put and be introduced into the present invention by quoting, such as DTMS transcranial magnetic stimulations circuit arrangement described in US2008200749A or U.S.'s Medtronic Mag Pro type magnetic stimulators of commercialization.

The excitement produced using Neural stem cell cortical motor area, makes spinal cord anterior horn cell or surrounding god by descending conduction path Depolarized through motor fiber, the potential change that recorded in respective muscle, nerve, spinal cord is Motion Evoked Potential detection thorn Swash.According to different stimulus modalities, SRPs can be divided into sensory evoked potential (somatosensory evoked potential, ) and Motion Evoked Potential (motion evoked potential, MEP) SEP.SEP mainly reflects the up conduction of spinal cord dorsal part Feel the function status of path, and the MEP stimulated through cranium then reflects the integrality of ventral side of spinal cord downward movement conduction path.By MEP contributes to whether detection backbone has substantive damage, has particularly with the latent lesion for not embodying obvious physical handicaps There is preferable flaw detection effect.MEP can be divided into Spinal motor evoked potentials (SCMEP), nervimotion Evoked ptential (MEP-N) and flesh Meat Motion Evoked Potential (MMEP), may be used as human body different parts neurotrosis detection and is used respectively.Maerten, Dvorak Et al. research point out that in vertebral disease and the protrusion of the intervertebral disc, MEP sensitiveness is 84%, 36% compared with SEP substantially increases Height, and MEP is slightly above lumbar spinal stenosis to the sensitiveness of spinal canal stenosis.Speculate with cervical spinal canal small volume, it is narrow after be more easy to Caused by compressing spinal cord.It is 85% that Machida, which has then reported the sensitiveness through cranium MEP Spinal Cord Injury of Trauma patients,.In order to logical Cross skull and scalp etc. and reach stimulation location, cause peak magnetic field is not smaller than 1 special by the selection of coil turn and current value Si La (T), typically should be between 1-2T.Tangentially relation sets flat board circular coil (its therewith at the top of user's skull Field stimulation is larger, is more suitable for peripheral nerve), its can be ironcore choke or built-up coil, coil diameter 12-20 centimetres it Between, hub of a spool is less than 3.5 centimetres away from user crown distance.Because being only used for physiological detection, therefore action time is short, using certainly So cool down or air cooling way.Via the coil, 1-3 centimetres of depth realizes fast frequency TMS in user's skull, also immediately The time-varying magnetic field frequency that time-dependent current is produced is more than 1Hz.The use of common motor potential detector is that can be achieved for being pierced through cranium magnetic Swash the detection of MEP signals, visited by analyzing the conventional indexs such as its conduction time and signal magnitude for spinal cord conduction path Wound.Such a situation should strictly forbid the mechanical massage for affected part or region of interest, it is to avoid follow-up massage step is produced for vertebra Raw secondary damage.

Secondly, periphery Nervous pathway can also be detected by MEP.The MEP of peripheral nerve acquisition methods with Existing SEP technologies are similar, by setting the anode of paster leading electrode in targeted muscles abdomen to be measured, and in neural descending tendon section Negative electrode is set, it is ensured that distance is on 35mm between electrode.Subcutaneous microneedle electrodes can be used instead if necessary and improve picking up signal effect Fruit and avoid noise jamming.It can be stated simultaneously according to patient master, carrying out MEP signals in specific limbs nerve pathway or neuromere picks up Take, and then targetedly pay close attention to the myoelectricity ripple conducted via specific spinal levels, can exist to specific nerve pathway and damage Wound carries out observational measurement.The selection of the targeted muscles is with the conventional selection standard of this area transcranial magnetic stimulation signal detection Can, in principle to be preferred at the four limbs major muscles away from trunk, it is not limited to wherein.

In MEP detects the waveform signal obtained, the first single-phase positive phase wave quickly reached is referred to as ground wave (D ripples), Because its conduction is transmitted without cynapse, so also referred to as ground wave；And one group of positive wave (I ripples) is occurred in that after D ripples, it is contact Caused by fiber indirect excitation cones, referred to as indirect wave.Electro photoluminescence draws MEP waveforms prompting spinal cord conduction beam function normally, And waveform disappears and shows that conduction function blocks, i.e. " all or none " or the decision principle of decreased amplitude 80%, it monitors sensitivity Degree is up to 100%.If there is D ripple blocks, classification will be made by gating circuit, forbids mechanical massage to carry out, anti-major structure Into treatment injury.And it is normal in the conduction of D ripples, and I ripple incubation periods lengthen (criterion is substantially between 2.5-5 times of ordinary duration) It imply that there is inflammation damnification, cause demyelinate symptom such as overwork.Clinical trial shows in patient without anesthesia waking state Under, double transcranial magnetic stimulation above, which can be simulated effectively, stimulates out normal induction signal.Appropriate mechanical massage is aided with magnetic The myoelectricity induced, which is stimulated, contributes to enlivening for neuron and conduction path.

Finally, checking with EMG method module also includes the pick device for myoelectricity (such as surface electromyogram signal), to detect Neuroelectricity conducting power.Terminate in MEP detections, judge that patient is not present spinal cord, neurotrosis etc. and is not suitable for mechanical massage After disease, myoelectricity pick device detects the electromyographic signal of the specific massage part of patient in real time.Muscle occur pain, spasm or During simple fatigue problem, problem points (including pain point, spasm point and tired area etc., it is as follows) peripheral nerve fiber conduction speed Degree slows down, poor blood circulation, and this also complies with general cognition.It can be obtained by the detection of electromyographic signal and made further Distinguish.

Recent kinematics research shows：Human skeletal muscle's slow switch fibers is more, and area percentage is bigger, the frequency of electromyographic signal MPF descending slopes are slower in domain analysis index.Further, pain especially chronic long pain can cause local muscle fast Muscle fibre accounting and volume increase and slow switch fibers is accordingly weakened, so as to cause MPF value descending slopes to significantly increase.For example, Clinical discovery teres minor muscle pathological inflammatory or non-pathologic spasm can cause dorsal root ganglia frequency of spontaneous discharges to increase Plus, radial pain as a result may be produced at corresponding side root pain and upper limbs.Problem points --- phase around painful area The generation of high frequency electrical signal can be had by closing nerve fiber, be presented as median frequency dramatic decrease, namely median frequency slope (median frequency slope, MPs) rise is obvious.Inventor thinks the height occurred during this nerve fibers conduct The quick interruption phenomenon of frequency, is a kind of adaptive phenomenon of human body under incomplete block.The high frequency intermittent phenomenon of problem points electric signal, So that organ-tissue peripheral cell electric charge quickly changes between increasing and reducing.This high frequency flash is both that a kind of physiology refers to Mark, can also exist as a kind of stimulation, treatment means.

And in the aching pain of muscles that sports fatigue is produced, it is emerging to maintain muscle tone to strengthen motor unit during due to fatigue The synchronism put forth energy；And the intramuscular caused blood flow of pressure increase is obstructed and the sarolemma surexcitation of generation is accumulated with lactic acid, so as to lead Muscle fiber conduction velocity reduction (muscle fiber conduction velocity) is caused, can be with this fatigue after exercise It is used as dominant index.It can realize that myoelectric amplitude is slowly raised by massage, physiotherapy, the frequency of average power of electromyographic signal (median power frequency, MPF) is also raised simultaneously, it is understood that rested for fast muscle fiber, lactic acid metabolism Recover normal with problem points blood circulation.

The electrode sample frequency for detecting pain signal is 300Hz-500Hz, preferably 450Hz；Tired signal detection electrode Setting sample frequency is 8-300Hz, more preferably preferably 20-100Hz, 50Hz.Common-mode rejection ratio is more than 120dB, sensitivity 1 μV.Pickoff electrode is using active surface electrode measurement fleshy exterior face electrical activity, and conduction region diameter is between 6-12mm.Electrode selects stone Electrode ink or Ti electrode, prevent it from occurring in magnetic field unexpected.

Place to smear patient's readme affected part using skin temperature allochroic paint before electrode and to backbone side extend and smear, the Pi Wenbian Color coating can effectively identify body surface temp different, muscular tone, spasm etc. influence blood circulation position and around and it is strong Side forms sharp contrast.The skin temperature allochroic paint uses palmityl alcohol, the binary mixture of two kinds of organic matters of myristyl alcohol to be molten Agent, color change interval is allowed between substantially 30-44 degrees Celsius by both adjustment with when processing technology, further in Between 33-40 degrees Celsius.Above-mentioned there is the low temperature point significantly lower than strong side and peripheral part to make mark.

Every group of three electrode are set centered on surrounding the mark point, active, measuring electrode line parallel to mark point at Main muscle fibre trend, electrode major axis itself is in the same direction with muscle fibre, spacing 2-2.5cm, and avoids being positioned on tendon as far as possible, in Property electrode be placed on above-mentioned mark point nearby voltage-neutral location.Strong side is symmetrically chosen, and equally sets one group of electrode.

Electromyographic signal in-situ processing device is connected with after electromyographic signal pick device, it is patrolled after realizing filtering, amplification Collect and judge, if the signal obtained in low-frequency sampling sequential enters tired signal and judges process；If in high frequency sampling time sequence The signal inside obtained then judges process into pain signal.In above-mentioned electromyographic signal judgement process, realize that fast Flourier becomes Its MPF value is got in return, to carry out frequency-domain analysis.Whether met using Matalab analyzers monitoring MPF values during frequency-domain analysis , for example there is rapid decrease in pre-set level or even flash (similar cliff of displacement formula declines) phenomenon then indicates that it enters alleviation pattern 2-1, Otherwise relaxed mode 2-2 is entered；Also it can be judged using adaptive neural network mode of learning, Binding experiment number of chambers evidence To natural spine both sides myoelectricity distribution map, human region myoelectricity is set to add for different heights, age, body weight or even Anthropometric parameters Weight coefficient table, is judged after Ipsilateral myoelectricity data/strong side data exceedes weight coefficient.

The working procedure of control module is carried out according to lower row logic during above-mentioned picking up signal：Detect transcranial magnetic stimulation Targeted muscles produce MEP signals, judge neural descending conductive link with the presence or absence of damage, be embodied in D ripples whether by It is correctly detecting；Then strictly forbid any type of mechanical massage if there is link conductive impairment；If MEP signals are normal Into real-time table facial muscle pyroelectric monitor process, mainly whether there is rapid decrease or even sudden strain of a muscle by MPF values in monitoring signals among these Disconnected phenomenon come determine enter which kind of massage mode, also can further combined with MPs signals and monitor electromyographic signal latent time.

In pattern 2-1 is alleviated, apply magnetostatic field, size 0.6-0.9T is arranged on above and below massage bed (or left and right) direction； Backbone side, which is traced back, in skin temperature indicating positions applies ultrasound, ultrasound convergence the depth 0.8-2.5cm, frequency 0.2-1.0MHz, work( Rate 1mW/cm²；Ultrasonic transducer used is close to skin, and transducer probe effective area 10mm × 8mm is longitudinally perpendicular in human body ridge Post direction.Ultrasound corresponds at substantially neuromere the convergent point for forming 1 sq, nerve fiber at this in hypodermis Middle cell membrane can be vibrated with intracytoplasmic charged particle, cause cell membrane depolarization according to Hall effect.Action electricity Position will be conducted to corresponding skeletal muscle, cause slightly to twitch or tremble.This action potential is sent by autologous patient neurode, tool There are altitude simulation and adaptability, induction obtains its size of action potential and supersonic frequency nonlinear correlation.At the same time, it is foregoing The electromyographic signal that supersonic frequency size is obtained with foregoing pickoff electrode makes adaptive change, and the feedback system causes myoelectricity MPF drop-out values reduce.Because " logical or nothing " characteristic of multiple neuron membrane depolarizations, clinically it is observed that above-mentioned induction The non-linear increase of current potential, namely its be likely to occur do not follow supersonic frequency adjust and the phenomenon of linear change.Control module pair The regulation of supersonic frequency is carried out in units of 0.1KHz, and the supersonic frequency adjusted every time keeps at least one more than the cycle, in week Period is every the above-mentioned MPF values of detection.

In relaxed mode 2-2, apply magnetostatic field (avoiding acting on user head), size is 2.5T, can be in massage (or left and right) direction is set above and below bed；Then indicate that selection temperature change most visibility point is used as gradient magnetic according to above-mentioned skin temperature Field action band center, applies gradient magnetic, and its size is 100mT, switching rate 10-15mT/m.s (y circles).Under its effect, on State tissue of the zone of action including nerve, muscle receptors and occur bioelectrical effect so as to occur visually imperceptible random Then belly of muscle is shaken, and it contributes to blood circulation and lactic acid metabolism, while being produced according to gradient magnetic switching rate difference more or less Heat.The heat of generation will cause the part for being coated with skin temperature allochroic paint to occur temperature change, reach the phase that wherein includes Becoming after material threshold will cause phase-change material to absorb heat liquefaction, so as to avoid skin fire damage.Meanwhile, operator can pass through The color monitoring skin temperature of skin temperature allochroic paint.In the dwelling period of gradient magnetic, myoelectricity acquisition module is started working the cycle When, above-mentioned phase-change material will also have an effect to avoid coated portion temperature too low, prevent skin, muscle and become due to cold and hot Muscle tonue causes electromyographic signal error caused by changing.

Electrocardiogram large sample analysis result for different parting cervical spondylosis patients shows cervical spondylopathy and electrocardiographic abnormality With larger correlation or even homogeneity, therefore the neck heart syndrome that is otherwise known as.The process of magnetic stimulation is being carried out to peripheral nerve The biological electricity of middle generation inevitably will partly overlap or even conflict with electrocardiosignal.Clinical data shows such case Particularly evident in patient with cervical Spondylopathy, the error burst of ultrasonic magnetic field therapeutic effect will be significantly increased.If can be further Ground increases heart real time detection in the above-mentioned magnetic therapy module course of work, it will is cut for ultrasonic magnetic therapy and provides more preferable opportunity and refer to Show.

Huo Dun (Holden) showed that vascular wall can produce an electrical potential difference in magnetostatic field in body surface in the research of 2004, The induction field may influence propagation (the The sensitivity of the heart to static of electrocardio action potential magnetic fields【J】.Progress in Biophysics＆Molecular Biology, 2005,87 (2-3)：289_ 320.).For the ECG detecting results such as three existing frequently-used leads, five leads, 12 lead, magnetostatic field induced electricity The influence of gesture is mainly reflected in the deformation of T ripples or delay.Magnetostatic field is treated in alleviation pattern 2-1 for example of the present invention, because magnetic field Intensity is smaller to be not enough to significantly affect electrocardio generation, but by detection and experimental result contrast still it can be seen that similar Interference of the bad electrical potential difference for therapeutic effect.In order to avoid interference can for electrocardiogram equipment set up reliable ground, wave filter and Metal housing etc..Further, electrocardiosignal can be caused to realize the ultrasound in S ripples triggering pattern 2-1 by circuit.

And during relaxed mode 2-2 field variation, the detection of electrocardiosignal tends to occur serious distortion, so such as What realizes the technical problem that more preferable magnetic therapy incision opportunity would be further desirable to solve.Carried out in Hebei Normal University《Abdomen Formula is breathed for Heart rate influences》The rhythm of the subjective control abdominal respiration of as shown by data obtained in experiment helps to control heart rate In a relatively low and stable level.The correlative study of same Xi'an Communications University also indicates that heart rate and breathing can be accomplished Interaction, its coupled relation will not be described here.In the present invention, relatively low heart rate is bioelectric to peripheral nerve dry for avoiding It is substantially favourable to disturb；Can there are an obvious loosening stage, the rank in the end of breath respiratory muscle of abdominal respiration simultaneously Section can reach 6-8 seconds by the conscious extension of user.The gradient magnetic switching rate in 2-2 massaging ways is now controlled to be Peak value, will obtain more preferable effect.Therefore the present invention further sets breathing instruction device, it uses the acousto-optic of any prior art Electricity etc. points out means, such as buzzer or LED flash decorations.For indicating that user carries out the frequency of abdominal respiration, together When user enter steady breathing state after coordinate gradient magnetic change, make the expiration of magnetic field switching frequency and abdominal respiration Stage keeps synchronous.Clinical trial shows that most of adults can keep when coordinating breathing instruction device to carry out abdominal respiration Respiratory rate per minute 5-7 times, while the relatively low heart rate level that heart rate will be dropped in its normal range (NR).Now combined magnetic field is controlled Therapeutic effect is significantly increased, in the case for the treatment of time is isometric, and the MPF values measured relative can rise 1%-10%.

Again further, medicine adjuvant treatment effect is increased in above-mentioned reduction system work process, it is by medication mould Block is realized, it is therefore intended that promote local location blood flow, improves the remission effect of muscular tone.The medicine uses this area Psoralen, promoting blood circulation proved recipe increase and decrease, are mixed into foregoing after active ingredient is further ground after boiling is purified known to technical staff The position for receiving magnetic therapy is coated in skin temperature allochroic paint.Skin is penetrated into after the process said medicine of Neural stem cell is heated to realize Drug effect.
