Description
Technical field
This utility model relates to a kind of electrostimulator for losing weight, and relates more specifically to the average amplitude of the set specific frequency signal of section sometime extracted from music audio signal and apply to have the electricity irritation of intensity corresponding with this average amplitude to reach the technology of antiobesity action in ensuing a period of time by electrode pair user.
Background technology
Fat oneself is through becoming Global prevalence disease at present, and that brings thus also comes into one's own gradually on the impact of human health and quality of life.Current people on the concern of obesity oneself through extending to complication that obesity causes to the damage of health from it to the impact of outward appearance, beauty treatment.Overweight patient often have with movable, sleep, problem that hypertension is relevant with hypercholesterolemia, other some serious risks also comprise: diabetes, coronary heart disease, hyperlipidemia, hypertension, gastroesophageal reflux disease, obstructive sleep apnea, low ventilation syndrome, apoplexy, osteoarthritis, pseudotumor cerebri, cholelithiasis, chronic varicose veins of the lower extremity and comprise colorectal cancer, carcinoma of prostate, gout, even asystole, renal failure and death etc.In addition, obese patient can experience and health concerns, psychological problems that social anxiety is relevant, and usually poor quality of life.
At present, the fat concern being also day by day subject to people of Gastric electrical stimulation (gastriceleetricalstimulatio, GES) treatment.The motion of stomach is brought out primarily of Weihe granules and regulates and controls, and comprises the change of Gastric accommodation and gastric emptying.In 1963, Gastric electrical stimulation oneself be used to gastrointestinal motility disorder, use on this basis exogenous electric pulse stimulation destroy obese patient normal gastric electricity one motor function from but the new ideas of Bariatric, nineteen ninety-five first Application treat in human obesity.GES is put electrode at the body surface projection point of stomach, provides the electric pulse stimulation signal of certain pattern by pulse generator, plays appetite-suppressing and slimming.Its operating technology comparatively bariatric surgery is simple, can not change gastrointestinal normal anatomical structures.Oneself nearly 2000 routine obese patients of the current whole world receive GES treatment, and result display GES makes overweight alleviate 5% one 35%, and its safety and reliability is also verified.The mechanism that GES treatment is fat: the mechanism of action of Gastric electrical stimulation to Bariatric comprises machinery (as gastric motility), neural and hormone path.The periphery mechanism of Gastric electrical stimulation comprises: (l) gastric slow wave changes: many research displays, and long pulse Gastric electrical stimulation (ripple is wide is hundreds of millisecond) energy pace-making or control gastric slow wave, usual Gastric electrical stimulation frequency comparatively gastric slow wave natural frequency is slightly high.(2) gastric antrum shrinks: an early stage dog test display short pulse Gastric electrical stimulation can increase gastric motility.But more tests can not confirm this result subsequently.Contrary long pulse Gastric electrical stimulation, when its frequency is the hyperfunction frequency of gastric antrum electrical activity, can suppress gastric antrum to shrink.This kind of Gastric electrical stimulation also can slow down gastric emptying and become the fat potential method of one for the treatment of.(3) stomach tension force and Gastric accommodation: multiple Gastric electrical stimulation method can change stomach (comprising at the bottom of stomach and gastric antrum) tension force and Gastric accommodation.GES, except causing flatulence, can also suppress stomach to shrink.ZhuHB etc. apply GES and carry out acute Gastric electrical stimulation to observe gastric antrum contraction after the meal to 8 Canis familiaris L.s.12 search time Duan Zhongke are recorded to 5 beats/min regularity in gastric antrum portion is shunk, and when carrying out GES, suppresses stomach to shrink completely at each stimulation time Duan Zhongke, can partly suppress stomach to shrink in 8 time periods.EagonJ etc. place bipolar electrode at 7 dog stomach near-ends and far-end, with carry out forward with reverse pace-making, detect gastric myoelectric fast wave, contraction movement and mixing test-meal gastric emptying.Found that, retrograde pace-making has reversed 90% gastric antrum current potential and peristalsis, extends the Late phase of Gastric Emptying of Solids, extends solid and liquid half-time emptying.(4) gastric emptying: multiple research dog and people shows long pulse Gastric electrical stimulation change gastric emptying.But series impulse Gastric electrical stimulation is still disputable to the change of gastric emptying.On the other hand, gastric antrum antidromicity long pulse Gastric electrical stimulation slows down dog and the gastric emptying mouth of people and studies further and show that Gastric electrical stimulation suppresses to reduce and Gastric accommodation lowers relevant with taking food to the gastric emptying of healthy volunteer.The impact of GES on central action comprises cental system and vagal effect.Recent Canidae research finds that vagus nerve participates in Gastric electrical stimulation effect, and Gastric electrical stimulation activates the neuron that nucleus solitarius is reacted flatulence.About 40% flatulence reaction neuron is activated by long pulse or series impulse Gastric electrical stimulation.The series impulse Gastric electrical stimulation having research to disclose treatment fat has impact to maincenter hormone, can reduce short appetite skin, increases and subtracts appetite skin.After the series impulse Gastric electrical stimulation of 2h, the neuron of expressing aricine depending on coker and lateral hypothalamus reduces, and increases at the neuron expression of expressing cholecystokinin.
Although features such as Gastric electrical stimulation treatment obesity has that wound is little, scalable and reversibilitys, and clinical and basis has obtained and has necessarily been in progress and confirms its curative effect, but in the patient accepting GES treatment, only 1/3 patient obtains Preferred effects, may there is individual variation to the reaction of Gastric electrical stimulation; For this reason, also have a lot of problem to need to solve, affect the treatment at present and the subject matter of clinical practice be applicable crowd selection, lack desirable Gastric electrical stimulation instrument and ideal parameters.Current electrostimulator adopts pulsating volage on pair of electrodes sheet and treatment human body resistance generation effect, and producing human body at therapentic part can the pulsating current of perception, and the muscle that excites nerve makes it shrink and diastole, produces exercise effect to reach therapeutic purposes.The most pulsating current frequency cycle of existing electrostimulator is fixed, if long-term receipt this kind of pulsation, body can produce anti-treatment effect, causes spontaneous nervous, will reduce the effect for the treatment of or fat-reducing.
