Description
Technical field
This utility model belongs to medical science Magnetic testi field, is specifically related to a kind of Nei Tan formula biological tissue magnetic scattergram measurement apparatus。
Background technology
The cell of organism, tissue or organ, such as the heart, brain, flesh, stomach, retina etc., can produce bioelectrical signals, including resting potential and action potential。Cell, under quiet state, is present in the charged ion skewness inside and outside cell membrane, forms potential difference, is called resting potential。When cell irriate, the ion inside and outside film can be reacted, and current potential can change, and forms action potential。Forming bioelectric current during above-mentioned potential change, bioelectric current can produce biological magnetic field。When pathological changes occurs at human body certain position, vivo biodistribution electric current and human magnetic field will change, and such as, normal bio tissue is different with the magnetic chart of cancerous tissue；Normal magnetocardiogram, magneticencephalogram, flesh magnetic chart are also different from magnetic chart time ill。In a word, at the magnetic signal of human body Different Organs or tissue sampling, it is possible to assist a physician the diagnosis cause of disease, has higher clinical reference value。Such as, magnetocardiogram may be used for Differential Diagnosis and finds myocardial ischemia, confirms coronary heart disease, confirmed myocardial necrosis etc., and magnetogastrogram may be used for diagnosis intestinal peptic digestion power, diagnosis ulcer and the observation medicine therapeutic effect to stomach functional disease。
In a lot of medical diagnosiss, magnetic chart is than the information contained by map of current more accurately, more comprehensively。For electrocardiogram and magnetocardiogram, electrocardiogram is from electrical activity produced by the body surface each cardiac cycle of record heart, and magnetocardiogram is magnetic signal produced by record electrocardio electric current。Both contrasts, there is following characteristics: first, ecg measurement is the potential difference being attached between two electrode slices of body surface, this potential difference is that electrocardiosignal have passed through human body conduction, there occurs that nonlinear change obtains, can not accurately extrapolate the distribution of internal electrocardio electric current, and nonlinear change that mcg-signals produces after each organizational communication of human body is less, the magnetic signal that measured magnetocardiogram energy direct reaction electrocardio electric current produces。Secondly, electrocardiogram can only measure the current signal of alternation, it is impossible to measures the current signal of direct current, and the field signal that magnetocardiogram can measure alternation simultaneously and DC current signal causes。In addition, ecg measurement needs to be attached to electrode slice body surface, and record is 2D signal, and the measurement apparatus of magnetic chart need not contact human body surface, therefore magnetic measuring device can move the magnetic chart obtaining three-dimensional in three dimensions, and the information comprised is more rich。Compared with electrocardiogram, magnetocardiogram can react heart body and change thereof better。
Owing to biopotential signals is in mV level, the biological magnetic signal being generated by is less。Being inversely proportional to according to Biot Savart law, the intensity in magnetic field and the cube of distance (referring to the distance of test point and Magnetic Field Source), after have passed through the transmission of human body, biological magnetic signal is significantly decayed, and extremely faint, such as core field intensity is about 10-10T, is about 10 with geomagnetic field intensity-4T-phase ratio, its intensity is about 1/1000000th of magnetic field of the earth, therefore that its detection is extremely difficult。It is applied in vitro at present carry out the equipment of so faint biological Magnetic testi and have Superconducting Quantum interferometer, it is a kind of equipment that can measure faint magnetic signal, cardinal principle is that magnetic flux is converted to voltage signal, it is mainly used in the biological magnetic measurement such as heart magnetic and brain magnetic, but the Superconducting Quantum interferometer come into operation now needs supporting magnetic shield room and uses liquid nitrogen cooling, in-convenience in use and costly。In a lot of fields of biological Magnetic testi, in the such as Magnetic testi of stomach, intestinal, esophagus, nasal cavity etc., magnetic measurement is not yet widely used in clinic。It is too high that main cause is because vitro detection instrument use cost, limited precision。
If magnetic can be received device extend into the inside of the detected biological tissue of human body, then can effectively shorten biological magnetic signal and receive the distance of device to magnetic, the intensity of magnetic signal is greatly improved, improve signal to noise ratio, therefore the accuracy of detection of magnetic scattergram can be improved, it is also possible to simplify the instrument of the biological magnetic signal of detection and use complexity。But, magnetic is received device and extend in tissue, certain discomfort can be brought to patient in checking process, but the medical inspection of this interior spy formula has precedent, such as originate from 1795, start to be promoted and wide variety of endoscope in eighties of last century, need during inspection to extend in the patient by optical instrument endoscope, and image is passed back, although these check to be with to patient serves discomfort, but it is that it improves the early detective rate of many major diseases, therefore there is important clinical meaning。
