Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly a kind of digital music electricity gastrointestinal pacemaker therapeutic instrument.
Background technology
(Functional Gastrointestinal Disorder FGID) is meant to have chronic and symptom of digestive tract recurrent to functional gastrointestinal disorder, but lacks the clinical syndrome that dissection, biochemistry and pathology change evidence.(Disorders of Gastrointestinal Motility DGIM) is meant with the gastrointestinal motility dysfunction to be one type of disease of main cause to gastrointestinal motility disorder property disease.FGID/DGIM is common clinical, frequently-occurring disease, and its crowd's prevalence is 10% ~ 30%, and the prescription on individual diagnosis patient accounts for 40%～60% of Gastroenterology dept.'s special outpatient clinic.But up to now; FGID/DGIM does not still have the specific treatment method; Medicine that its Therapeutic Method mainly relies on short digestive tract power, presses down sour medicine, regulates visceral sense, anxiety is depressed and psychological cognition treatment etc., but the drug side effect that has is big, and what have can not obtain satisfied curative effect; And be prone to recurrence after the drug withdrawal, curative effect is subject to the influence of other factors.
Different music can produce different reactions to people's physiology, like biochemical substances (epinephrine, norepinephrine, endorphins, immunoglobulin) and brain wave or the like in speed, blood pressure, skin potential response, muscle current potential and motor reaction, endocrine and the body of heart rate and pulse.The rhythm of music can influence people's behavior rhythm and circadian rhythm significantly, for example respiration rate, gastrointestinal motility speed rhythm, heart rate.In addition, different music can cause various very different emotional responses.Music also is a kind of form of communication of uniqueness simultaneously, and for music, most important interchange meaning is non-language.These interchange characteristics of music are crucial key factors for clinical treatment, and particularly when the effort fall through of language, music can help to set up good doctor-patient relationship, and this relation is treated successful basic motive just.In addition; Because music is a kind of a kind of exist actually that is present in the time and is formed by physical arrangement (vibrations of air molecule); Therefore music can become an effective media and helps those patients that from reality and society, shrink back out from the world that newly comes back to earth, and sets up and the getting in touch of outside real world.In a word, the utilization one of music is many-sidedly to stimulate cerebral cortex, makes patient's decreased sensation to external world; The 2nd, thought contact and the emotion that can arouse patient's happiness are temporarily forgotten the environment of staying; The 3rd, music has direct inhibitory action to nervus centralis.The glamour of alternative music and fragrance also can attract those social people that shrink back to participate in the social activity of music to go, thereby change its self-isolation state.
At present, North America, South America, Europe, Australia and in recent years some countries in Asia all carried out various forms of musical therapies.In recent years, along with the development of electronic technology and Computer Control Technology, the novel music electric therapeutic apparatus is constantly released.France Ai Fuer international corporation is walked in the prostatitis in the world present musical electro-therapy instrument development aspect; The U.S. breast care instrument of its company's main product music merges multiple frontier branch of science latest scientific research such as contemporary musical therapy, psychological intervention technology, Chinese and western medical science, electronic engineering, automatization's control; In the world; With the Therapeutic Method such as unique physical therapeutical effect of the psychological application of music and sound field physiological action, music electricity, integrated application is in health care, the nursing of female breast first.In China, musical therapy is the signs that are created as with musical electrotherapy as the subject in modern times, has developed sea God 99-A music electrical therapentic instrument, YP-I music electrical therapentic instrument, the synchronous physical therapy machine of sound electricity etc.China medical personnel also combines music therapy, electrical stimulating therapy with China tradition meridian theory, created " musical electrotherapy ", and the traditional medicine of motherland has been advanced again a step.Though musical electro-therapy has the history of decades; Musical electro-therapy and Musical Electro-acupuncture Therapy are widely used in the rubble etc. that muscle is turned round damage, sciatica, facial paralysis, neurasthenia, initial stage hypertension, apoplexy sequela, renal calculus, but are simple physiotherapy or music modulation.Up to now, Shang Weijian is superimposed on the bioelectrical signals of human body with the music modulated current, the report that utilization bio electricity resonance principle and biofeedback mechanism are treated.The research in gastrointestinal pacemaker field at first originates from abroad; It is main inserting electrode brief burst stimulation acute experiment with percutaneous endoscopic mucosa adsorption electrode or peritoneoscope serous coat at first; The pace-making direction has reverse pace-making and forward pace-making, and explores its influence to digestive tract power.These experimentatioies have proved the existence of gastrointestinal pacemaker system.The clinical application research of carrying out subsequently proves that also the gastrointestinal pacemaker stimulation all has obvious curative effects to diabetic gastroparesis, gastroesophageal reflux, functional dyspepsia, gastroptosis and surgical postoperative restoration of gastrointestinal function.The focus of at present external gastrointestinal pacemaker concentrates on the research that " optimal parameter of pace-making " reaches " mode of cardiac pacing ".But foreign study is main with implanted gastrointestinal pacemaker scheme, stresses to directly act on the stomach pacemake.Although it has the advantage of accurate positioning, wound is big, and electrode comes off easily, is not easy to very much clinical and family's use.
The research of domestic relevant gastrointestinal pacemaker is later, and the research of present domestic association area mainly is effect and the mechanism thereof of inquiring into external gastrointestinal pacemaker and electroacupuncture treatment gastrointestinal motility disorders property disease, has obtained certain progress.With abroad compare, domestic gastrointestinal pacemaker therapeutic scheme mainly is based on surface electrical stimulation pace-making and acupoint, has avoided operating intervention, reduces application risk greatly, more likely is fit to long-time use clinical and family.But its shortcoming is a gastrointestinal pacemaker waveform and frequency is single, the pacing parameter relative fixed, a little less than the selective stimulating effect, is prone to produce adaptability, and the curative effect of pace-making is single and not lasting, can not satisfy the needs of the meticulous treatment of clinical individuation.So explore safe and effective, have no side effect, the selective stimulating effect and do not produce adaptability, new method easy to use has crucial meaning.
Though musical electro-therapy and gastrointestinal pacemaker rise the history of existing more than ten years at home and abroad; But up to now, domestic and international no-trump digital music current loading still is in the report of the curative effect of the electric gastrointestinal pacemaker of the digital music of intrasonic gastrointestinal pacemaker first-harmonic and treatment gastrointestinal motility disorder property disease/functional gastrointestinal disorder thereof.
