Osteoporosis therapy system based on the last of the twelve Earthly Branches parent nucleus magnetic coil that makes a variation

Technical field:

This utility model relates to a kind of armarium, especially based on the osteoporosis therapy system of last of the twelve Earthly Branches parent nucleus magnetic coil of variation.

Background technology:

China has patients with osteoporosis 9,000 ten thousand people approximately at present.The correlation study data shows that senile osteoporosis disease prevalence male is 60.72%, and the women is 90.47%.WHO classifies osteoporosis as be only second to the cardiovascular diseases second largest public health problem.

Osteoporosis shows as the loss of bone amount and skeletal tissue's micro structure is degenerated, and this disease can cause skeleton fragility to increase. and make patient Geng Yi fracture.So because the origin cause of formation of osteoporosis is very complicated. treatment has bigger difficulty.In recent years, the multiple method of utilizing medicine and food therapy osteoporosis has appearred.Although the effect of some of them medicine determined, because there is intolerance in some patient for individual drug or suffers from the use contraindication of some drugs, and the danger of long-term prescription existence, limited the use of medicine.For osteoporosis. common naturopathy method is to utilize low frequency pulsating magnetic field to treat.The biological effect in magnetic field can activate the metabolism of dormancy osteocyte again, and foot advances bone tissue growth.

Magnetic field is to the mechanism of action of human body: (1) electrodynamics theory: all magnetic phenomenons all are that the essence of magnetic phenomenon is exactly the motion of electric charge because moving charge produces.Magnetic field is to electric charge, and a magnetic field all can produce active force to another magnetic field.Magnetic field produces Lorentz force to moving charge, and current is produced Ampere force; Magnetic field energy changes atom and the orbital magnetic moment of molecule and the direction of spin magnetic moment; By the electromagnetic induction effect, magnetic field can also make conductor produce induction electromotive force and faradic current.The biological physics view point of tissue people is seen, be extremely complicated, in magnetic field, will be subjected to the various effects in magnetic field and produce various effects: A. producing little electric current, the various body fluid of human body all are electrolyte solutions, belong to conductor, in alternating magnetic field, the magnetic line of force is done the motion of cutting conductor, will produce induced current; Along with the contraction and the diastole of heart, blood vessel also ceaselessly moves, and blood also is constantly mobile, so though be the stationary magnetic field, because the motion of blood vessel and blood flow is cut the magnetic line of force, also will produce electric current in vivo.It is very small and weak carrying out the induced current that magnetic therapy produced, promptly little electric current.The generation of little electric current can make a difference to bioelectric in the body, thereby influences the metabolism and the function of each tissue of each organ.Under action of alternating magnetic field, Na ⁺, K ⁺, Cl ^-Isoionic mobility is strengthened, and has changed transmembrane potential, strengthens the permeability of cell membrane, promotes the exchange of the inside and outside material of cell membrane etc.B. there are various bioelectric currents in magnetic field to bioelectric effect in the human body, as electrocardio, brain electricity, myoelectricity and nerve action potential etc.Bio electricity is the important component part of physiological activity.Under the action of a magnetic field, bioelectric current will be subjected to the effect of magnetic field force, and promptly will have an effect to distribution, charge movement form and the energy state thereof of bioelectric current in magnetic field, thereby cause that the function of related organization's organ takes place by corresponding the variation.In addition, in the redox reaction process of organism, the transmission of electronics takes place; Magnetic field may influence biochemical reaction process to electron transfer process generation effect.(2) zymetology is said: enzyme generates in cell, and its chemical nature belongs to proteinic biocatalyzer.The catalytic activity of some enzyme except protein portion, also needs metal ion, and promptly metal ion is the ingredient of enzyme active center.Though do not contain metal in the molecule of some enzyme, need metal ion to activate.Many phosphoric acid transferring enzymeses need Mg ⁺⁺, the enzyme require Co of many hydrolysising peptide keys ⁺⁺, Mn ⁺⁺, Mg ⁺⁺Or Zn ⁺⁺Activation, just be transformed into and have active enzyme.In addition, Na ⁺, K ⁺, Ca ⁺⁺, Cu ⁺⁺Deng kind of cation and some anion (Cl surplus ten ^-) wait all some enzyme is had activation.The catalytic activity to the function influence enzyme of above-mentioned metal ion and nonmetallic ion may be passed through in magnetic field, and to human body generation effect.Someone thinks the magnetic field effects such as reaction that sedation-analgesia arranged, bring high blood pressure down and reduce inflammation, and the activity that improves cholinesterase, monoamine oxidase, MAO, histaminase and kininase with magnetic field is relevant.(3) through cavitation: the magnetic therapy of numerous disease is to be used for the acupuncture point and to produce curative effect.For example magnetic sheet sticks big vertebra, fei shu, Danzhong treatment asthmatic bronchitis, and the refreshing threshold of gyromagnet effect has remarkable antidiarrheal curative effect etc.Studies confirm that there is the electrical activity phenomenon in acupuncture point meridian.There is higher current potential at the acupuncture point than surrounding skin.When certain organ function was hyperfunction, the skin potential of corresponding meridian point increased or resistance value descends; When certain organ activity miopragia, the skin potential of corresponding meridian point also decreases, and resistance value then raises.Therefore, magnetic field may influence meridians is electromagnetic activity process and play the function regulating action.(4) neuroendocrine effect: the action of a magnetic field is when whole body, and each system participates in the degree of reaction and can arrange in the following order: nerve, endocrine, sensory organ, cardiovascular, blood, digestion, muscle, drainage, breathing, skin, bone.Nerve and humoral system are the most responsive to the effect in magnetic field, i.e. in the reaction of body to the action of a magnetic field, neural and hormonal system plays an important role.When the action of a magnetic field, nerve can participate in the quick impression system of primitive reaction, also participates in its slow impression system.When low-intensity magnetic field effect during the long period, also can cause the reaction of slow system.Hormonal system also obviously participates in the reaction of body to the action of a magnetic field.Under the action of a magnetic field, observing some hormone secretion of animal increases.
