Description

One kind triggering Magnetotherapeutic apparatus for backbone reduction system electrocardio

Technical field

This application involves spine recovering fields, and in particular to the convalescence device of a kind of backbone and muscle.

Background technology

Modern causes body a part to be chronically at due to seat work, bad life habits and disease or certain Anchor, muscle are chronically at the state of underload contracts last.This can cause moisture in the fibr tissues matrix such as ligament to subtract Few, viscoelasticity weakens, and interfibrous lubricating action reduces.Meanwhile interfibrous hypotelorism, contact phase extend, this may lead It causes to generate the horizontal key of chemistry between fiber, stick together so as to cause between fiber.And such crowd is often because of the chronic inflammation of muscular tissue Disease and lead to newborn fiber, these newborn fiber alignments are disorderly, form adhesion again with original fiber, further limit fibre Sliding between dimension.Long it, this " vicious circle " will cause muscle that slight contracture occurs, and cause muscle tonue.The life of modern Mode living determines that such muscle tonue mostly occurs 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, or even meeting should be inevitably caused in the process (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.Unexpected massage damage also often occurs in the massage processes of non-spinal damage simultaneously.So It needs to provide effectively real-time electrophysiologic monitoring means when being related to spinal treatments.How electro physiology to be detected and a variety of backbone health It is a direction that this field has much development prospect that multiple means, which combine,.It is obtained in numerous electrophysiological indexs effectively and has generation The data of table, and with the emphasis of its progress and this field research of instructing follow-up spine recovering.

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

Electromyography signal (EMG) is a kind of adjoint muscular movement and the bioelectrical signals generated.In the limb motion of people, greatly The neuronal excitation in controlled motion region and the electric pulse of certain frequency is generated in cortex, this electric pulse passes through nervous system Specific meat fiber is accurately conducted, when these electric pulses reach a neural muscle cynapse, soleplate is generated in muscle fibre Current potential, its depolarising will generate a series of movements current potential in muscle fibre, and cause contraction of muscle, and limbs is made to complete set by brain Action.Surface EMG is the synthesis physiology electrical phenomena that each section muscle activity is generated in limb motion, is divided surface EMG Analysis research can find its correspondence 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 are Severe Pain points in muscle muscle tonue band The viewpoint of (myofascial trigger point, MTrP) is widely recognized as.It can be recorded in the areas MTrP 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 Adjusting appropriate can also be made to muscle tonue in such a way that impressed field influences myoelectricity.

It exists in the prior art by carrying out electro photoluminescence to patient and receiving myoelectricity/biofeedback signals of patient, to 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 includes that waveform is simple.It is single to the effect of stimulation of human body, be easy to cause peripheral nerve fatigue and production Raw a large amount of unnecessary electrode heat.Skin keratin lesion may then be led to and bring unnecessary damage by being inserted into electrode or patch electrode Wound.Patient will produce the unnecessary imagination for intuitive visible electrode stimulating, and such psychology also results in therapeutic effect deterioration. Most importantly peripheral nerve may react good for stimulating in short term, but long-term treatment can cause neural fatigue, effect also can It is plummeted.Reason is in evolutionary process that human nerve stress reflect the injury that environmental stimuli generates that there are one adapted 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 the identical neuron cell body of function other than the maincenter around nodositas structure made of the set of position It makes.Its surface is surrounded by one layer of connective tissue membrane, wherein containing blood vessel, nerve and adipocyte.Envelope and perineural outer membrane, god It connects together through beam film, and gos deep into neuromere forming the network in neuromere.The fiber sent out by nerve cell in section It is distributed to the related part of body, claims postganglionic fibers.By the difference of physiology and form, neuromere can be spinal ganglion (sensibility god Warp knuckle) and two class of automatic ganglia.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 near institute's dominating organs or in organ walls.In neuromere, aixs cylinder and the postganglionic neuron group of preganglionic neuron At cynapse.Neuromere is associated by nerve fibre with brain, spinal cord.

Inventor is tested by the physiology that laboratory carries out and is found：By stimulating the nervous system including neuromere to lead Cause the bioelectricity that human body generates inaccurate controllable in amplitude, frequency, and the bioelectricity peomotes the controlled muscle of nerve, knot Form group with being woven with 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 inevitably there is a situation where being interfered with each other with electrocardiosignal during Neural stem cell, Above-mentioned interference can also be improved in such a way that electrocardio triggers magnetic stimulation circuit while being shielded, this is also this field skill Art personnel are difficult to technical problem urgently to be resolved hurrily.Meanwhile how easy quickly and non-invasively stimulation sites to be accurately positioned It is then the problem that those skilled in the art do not overcome.Previous physical therapy practitioner often through experience press and patient feedback into Row positioning, both inaccuracy may also cause accidental injury in this way；Certainly also it has been proposed that being measured by adding electrode, still Laboratory environment and clinic differ greatly, and testing cost is high very high simultaneously for operator's requirement.

Invention content

The present invention provide it is a kind of alleviate for patient spine damage, backbone fatigue and related muscle group anxiety, treatment it is whole Complex system.The shortcomings that can only being directed to single spinal problems which overcome previous reduction device, comprehensive a variety for the treatment of means, default It detects and realizes intelligent therapeutic under the monitoring of program.Simultaneously as in view of the same presentation of user is that may be present a variety of pathogenic 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 physical therapy.To realize backbone reduction, rehabilitation effectively, safe, unnecessary secondary damage or delay are avoided.

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

The present invention relates to electro physiology and electromagnetism medical domains.Myoelectricity (EMG) signal known to us, amplitude, frequency spectrum With own characteristic：The surface EMG signal measured from body surface is usually very faint, and amplitude is usually no more than 5mV；Frequency also compares Relatively low, spectral range is generally 0.02-1000Hz, and spectrum energy is concentrated mainly between 0.25~350Hz.The relaxation of muscle and There are good linear relationships between tensity and generation surface myoelectric voltage amplitude.It is square to measure myoelectricity voltage magnitude use Root method can not only reflect the variation characteristic of EMG signal amplitude on time dimension, but also depend on muscle load sexual factor and muscle Inner link between physiology itself, biochemical process, therefore, which is commonly used in real time, with no damage Reflect muscle activity state, there is preferable real-time.Meanwhile the impedance of human muscle part can effectively state human body and loosen Degree, in general human body are more loosened, and impedance is smaller.Therefore human body flesh can in real time, accurately be obtained using the above method by combining Meat tensity, and it is classified.

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

First, transcranial magnetic stimulation (TMS) first is implemented to user, selected stimulated zone is located at Epidural cavity, is lured by magnetic field Send out potentiometric detection.Simple magnetic stimulator is by DC power supply, charging circuit, energy-storage travelling wave tube, discharge switch, charge-discharge control circuit With a few part compositions such as coil.Various transcranial magnetic stimulation instruments well known to those skilled in the art and the control dress including software Set and the present invention be introduced by reference, for example, DTMS transcranial magnetic stimulations circuit device described in US2008200749A or The U.S.'s Medtronic Mag Pro type magnetic stimulators being commercialized.

Using the excitement that Neural stem cell cortical motor area generates, spinal cord anterior horn cell or surrounding god are made by downlink conduction path It is depolarized through motor fiber, is Motion Evoked Potential detection thorn in the potential change that respective muscle, nerve, spinal cord are recorded 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 conduction of spinal cord back side uplink Feel the function status of access, and the MEP stimulated through cranium then reflects the integrality of ventral side of spinal cord downward movement conduction path.By MEP helps to detect whether backbone has substantive damage, has particularly with the latent lesion for not embodying apparent 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, the sensibility of MEP is 84%, 36% compared with SEP obviously increases Height, and MEP is slightly above lumbar spinal stenosis to the sensibility of spinal canal stenosis.Supposition is small with cervical spinal canal, is more easy to after narrow It oppresses caused by spinal cord.It is 85% that Machida, which has then reported the sensibility through cranium MEP Spinal Cord Injury of Trauma patients,.In order to logical It crosses skull and scalp etc. and reaches stimulation location, make peak magnetic field not be smaller than 1 spy by the selection of coil turn and current value Si La (T), generally should be between 1-2T.Tablet circular coil (its is arranged in tangentially relationship therewith at the top of user's skull Field stimulation is larger, is more suitable for peripheral nerve), 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 used only for physiological detection, therefore action time is short, using certainly Right cooling 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 generates is more than 1Hz.It can be realized using common motor potential detector for being pierced through cranium magnetic The detection for swashing MEP signals, visits spinal cord conduction path by analyzing the conventional indexs such as its conduction time and signal magnitude Wound.Such situation should strictly forbid the mechanical massage for affected part or region of interest, avoid subsequently massaging step for vertebra production Raw secondary damage.

Secondly, periphery Nervous pathway can be also detected by MEP.The acquisition methods of the MEP of peripheral nerve with Existing SEP technologies are similar, by the way that the anode of patch leading electrode is arranged in targeted muscles abdomen to be measured, and in neural downlink tendon section Cathode is set, it is ensured that distance is on 35mm between electrode.Subcutaneous microneedle electrodes can be used instead when 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 It takes, and then targetedly pays close attention to the myoelectricity wave 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 field transcranial magnetic stimulation signal detection Can, in principle to be preferred at the four limbs major muscles far from trunk, it is not limited to wherein.

In the detected waveform signals of MEP, the first single-phase positive phase wave quickly reached is known as ground wave (D waves), Because its conduction is transmitted without cynapse, so also referred to as ground wave；And occur one group of positive wave (I waves) after D waves, it is contact Caused by fiber indirect excitation pyramidal cell, referred to as indirect wave.Electro photoluminescence draws MEP waveforms and prompts spinal cord conduction beam function normal, And waveform disappearance shows that conduction function blocks, i.e. " all or none " or the decision principle of decreased amplitude 80%, monitoring is sensitive Degree is up to 100%.If there is D wave blocks, classification will be made by gating circuit, mechanical massage is forbidden to carry out, anti-major structure It is injured at treatment.And it is normal in the conduction of D waves, and I wave incubation periods lengthen (criterion is substantially between 2.5-5 times of ordinary duration) Imply that there are inflammation damnifications, such as overwork etc. to lead to demyelinate symptom.Clinical trial shows in patient without anesthesia waking state Under, above transcranial magnetic stimulation, which can be simulated effectively, twice in succession stimulates out normal induction signal.Appropriate mechanical massage is aided with magnetic The myoelectricity induced stimulation contributes to enlivening for neuron and conduction path.

Finally, checking with EMG method module further includes the pick device for myoelectricity (such as surface electromyogram signal), to detect Neuroelectricity conducting power.Terminate in MEP detections, judging patient, there is no spinal cord, neurotrosises etc. not to be suitable for mechanical massage After disease, myoelectricity pick device detects the electromyography signal of the specific massage part of patient in real time.Muscle occur pain, spasm or When simple fatigue problem, problem (including pain point, spasm point and tired area etc., the same below) peripheral nerve fiber conduction speed Degree slows down, poor blood circulation, this also complies with general cognition.It can be obtained by the detection of electromyography signal and be made further It distinguishes.

Recent kinematics research shows that：Human skeletal muscle's slow switch fibers is more, and area percentage is bigger, the frequency of electromyography 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, and are significantly increased so as to cause MPF value descending slopes.For example, Clinical discovery teres minor pathological inflammatory or non-pathologic spasm can cause dorsal root ganglia frequency of spontaneous discharges to increase Add, radial pain as a result may be generated at corresponding side root pain and upper limb.Problem --- 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) increases apparent.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 electric signal, So that organ-tissue peripheral cell charge quickly changes between increasing and reducing.This high frequency flash is both that a kind of physiology refers to Mark, also can be used as it is a kind of stimulation, treatment means exist.

And in the aching pain of muscles that sports fatigue generates, it is emerging to maintain muscle tone to strengthen motor unit when due to fatigue The synchronism put forth energy；And intramuscular pressure increases the sarolemma surexcitation that caused blood flow is obstructed with lactic acid accumulation generation, to lead Muscle fiber conduction velocity is caused to reduce (muscle fiber conduction velocity), it can be in this fatigue after exercise As dominant index.It may be implemented myoelectric amplitude and slowly increased by massage, physical therapy, the frequency of average power of electromyography signal (median power frequency, MPF) is also raised simultaneously, it is understood that it is rested for fast muscle fiber, lactic acid metabolism Restore normal with problem 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, preferably 20-100Hz, more preferably 50Hz.Common-mode rejection ratio is more than 120dB, sensitivity 1 μV.Pickoff electrode measures fleshy exterior face electrical activity using active surface electrode, and conduction region diameter is between 6-12mm.Electrode selects stone Electrode ink or Ti electrode, prevent it from accident occurring in magnetic field.

Patient's readme affected part is smeared using skin temperature allochroic paint before placing electrode and extends smearing, the Pi Wenbian to backbone side 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 the binary mixture of two kinds of palmityl alcohol, myristyl alcohol organic matters to be molten Agent is allowed to color change interval between substantially 30-44 degrees Celsius by adjusting the two 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 label.

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

It is connected with electromyography signal in-situ processing device after electromyography signal pick device, is patrolled after realizing filtering, amplification It collects and judges, 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 electromyography 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 enter relaxed mode 2-2；Adaptive neural network mode of learning can also be used to judge, Binding experiment number of chambers evidence obtains To natural spine both sides myoelectricity distribution map, add for different heights, age, weight or even Anthropometric parameters setting human region myoelectricity Weight coefficient table judges after Ipsilateral myoelectricity data/strong side data is more than weighting 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 generate MEP signals, judge neural downlink conductive link with the presence or absence of damage, be embodied in D waves whether by It is correctly detecting；Then strictly forbid any type of mechanical massage if there is link conductive impairment；If MEP signals normally if 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 electromyography signal latent time.

In alleviating pattern 2-1, apply magnetostatic field, (or left and right) direction is arranged above and below massage bed in size 0.6-0.9T； Backbone side, which is traced back, in skin temperature indicating positions applies ultrasound, the ultrasound convergence depth 0.8-2.5cm, frequency 0.2-1.0MHz, work( Rate 1mW/cm²；Ultrasonic transducer used is close to skin, transducer probe effective area 10mm × 8mm, longitudinally perpendicular in human body ridge Column direction.Ultrasound corresponds at substantially neuromere the convergent point for forming 1 square centimeter area, nerve fiber at this in subcutaneous tissue Middle cell wall can be vibrated with intracytoplasmic charged particle, lead to 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 out by autologous patient neurode, tool There are altitude simulation and adaptability, induction to obtain its size of action potential and supersonic frequency nonlinear correlation.At the same time, aforementioned Supersonic frequency size makes adaptive change with the electromyography signal that aforementioned pickoff electrode obtains, which makes myoelectricity MPF drop-out values reduce.Because of " 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 that linear change.Control module pair The adjusting of supersonic frequency is carried out as unit of 0.1KHz, and the supersonic frequency adjusted every time is kept at least one period or more, 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 2.5T can massaged Bed (or left and right) direction setting up and down；Then select temperature change most visibility point as gradient magnetic according to the instruction of above-mentioned skin temperature Field action band center, applies gradient magnetic, size 100mT, switching rate 10-15mT/m.s (y circles).Under its effect, on It is imperceptible random to which naked eyes occur to state tissue generation bioelectrical effect of the zone of action including nerve, muscle receptors Then belly of muscle is shaken, and contributes to blood circulation and lactic acid metabolism, while generating more or less according to gradient magnetic switching rate difference Heat.The heat of generation will cause the part for being coated with skin temperature allochroic paint that temperature change occurs, and reach phase wherein included Phase-change material will be caused to absorb heat liquefaction after becoming material threshold, to avoid skin thermal damage.Meanwhile operator can pass through The color of skin temperature allochroic paint monitors skin temperature.In the dwelling period of gradient magnetic, myoelectricity acquisition module is started to work the period When, above-mentioned phase-change material will also have an effect too low to avoid coated portion temperature, prevent skin, muscle due to cold and hot change Muscle tonue causes electromyography signal error caused by changing.

Electrocardiogram large sample analysis for different parting cervical spondylosis patients is the result shows that cervical spondylosis and electrocardiographic abnormality With larger correlation or even homogeneity, therefore the neck heart syndrome that is otherwise known as.In the process for carrying out magnetic stimulation to peripheral nerve The bioelectricity 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 significantly increase.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 better opportunity and refer to Show.

Huo Dun (Holden) 2004 research shows that vascular wall in magnetostatic field can in body surface generate a potential difference, 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 detectings 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 waves or delay.Magnetostatic field is treated in alleviation pattern 2-1 for example of the present invention, because of magnetic field Intensity is smaller to be not enough to significantly affect electrocardio generation, but by detection and experimental result comparison still it can be seen that similar Interference of the bad potential difference for therapeutic effect.In order to avoid interference can be electrocardiogram equipment add reliable ground, filter and Metal casing etc..Further, electrocardiosignal can be made to realize the ultrasound in S waves triggering pattern 2-1 by circuit.

And during the field variation of relaxed mode 2-2, the detection of electrocardiosignal tends to occur serious distortion, so such as What realizes the technical issues of better magnetic therapy incision opportunity would be further desirable to solve.It is carried out in Hebei Normal University《Abdomen Formula is breathed for Heart rate influences》It is being obtained in experiment statistics indicate that it is subjective control abdominal respiration rhythm contribute 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, this will not be repeated here for coupled relation.In the present invention, lower heart rate is bioelectric to peripheral nerve dry for avoiding It is apparent advantageous 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 control 2-2 massaging ways is at this time Peak value will obtain better effect.Therefore breathing instruction device is further arranged in the present invention, uses the acousto-optic of any prior art Electricity etc. prompts means, such as buzzer or LED flash decorations.It is used to indicate the frequency that user carries out abdominal respiration, together When user enter steady respiratory state after coordinate gradient magnetic variation, make the expiration of magnetic field switching frequency and abdominal respiration Stage keeps synchronizing.Clinical trial shows that most of adults can keep when cooperation breathing instruction device carries out abdominal respiration 5-7 times per minute respiratory rate, while the relatively low heart rate level that heart rate will drop in its normal range (NR).Combined magnetic field is controlled at this time Therapeutic effect is significantly increased, and in the case for the treatment of time is isometric, the MPF values measured can be differed with respect to 1%-10% is risen.

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