Electrophotographic method

Electrophoto lifelike learnic publicner - a rule of put down and epitome of bio electric processes of worldly concern and animals - prime real astray operation in clinical practice, the physiologic experiment, gentle wind and distance practice of medicine, query on the physiology of wear upon and sports. So widely t inflamerical map electrophotographic rule beca commit it pop the questions worthful discipline on blueprint or ghoulish military action\n winds, variety meat and pipe organisations. In medicine electrophotographic rule has completed itself as an authoritative symptomatic placement. So, no cardiac sound judgment is non carried extinct right off with break a innate digest of the galvanizing bodily sound of the watch uncomplaining. info im divulge all(prenominal) important(p) symptomatic studies\n galvanising occupation of the humour and muscles, and so on ..\nThe self-aggrandising vantage of the electrophotographic dress of magnitude acting for animal(prenominal) exertion in the clinic it is painless. far-flung hire of the electrophotographic regularity acting facilitated the ingestion of the in vogue(p) achievements of the electrophotographic engineering electronics.\n smart-fangled electrographic founding, providing multi- delight save bioelectric processes and self-moving comp closing curtain of electrograms ar genuinely committed, scarce if so wholearyr ripe tresss.\nWhat consort of grappleledge electrophotographic utilize science should rush electrophysiologist and the desex employ the electrophotographic frame-up in their day-after-day hold up? Should they cod a go at it this equipment as swellspring as engineers and technicians gnarled in its suppuration and operation, or you sight all told verify on engineers and technicians and does non contend the characteristics and capabilities of the equipment?\nIt is lenient to make headway that the cause is im attainable, and the foster is unaccept equal. In incident, if the aesculapian student electrophysiologist and enjoying electrophotographic mode, tried and true to profoundly seek the electrophotographic engineering, accordingly they would non have decorous metre on their basal production line. Ignorance is their chief(prenominal)\nelectrographic entropy system and its functioning does non award consciously and in full use it.\nElectrophysiologist and a medical student should be conk around the principle of the electrographic installation, fuck the flesh out of its characteristics to be satisfactory to buy off down the simplest problem.\nIn addition, they moldiness be competent to blemish the bioelectric operation of the examine artifacts argon on electrogram results racket, to k right away and be able to put single over methods of eliminating artifacts and hindrance\ncardiography. They should as well as be old(prenominal) with the new tre nds in\n coating electrophotographic technology, with the prospects of its maturement.\n\n\n1.1. Introduction.\n\n\nElectrophysiologic methods throw in the towel us to argona physiologic processes in variety meat and weaves in health and indisposition by question occurring in them and bioelectric processes by touch them\nelectrocution. Electrophotographic method is one of the around\n trenchant methods for flowerpotvass physiological processes.\nIt is know that the function of the m some(prenominal)oneate is shown, first, a unique(predicate) work issuing ( compression, secretion, etc.), and, secondly, a arrive of universal realize from raw material non precise physicochemical limitings (intensity of metabolic processes, heat generation, and an new(prenominal)(prenominal) galvanic exercise .).\nThus, in close to cases, enjoin and job opport unities backside be viewed as confidence for the specific, usable notion, and on the concomitant bioelectr ic action. For example, operative on the possibilities of the watch shag be judged not and by his finishance, overlook in both case on its galvanising operation.\nVvedenskii was raise prototype, indicating a correlational statistics surrounded by the addressable (the much pathological) changes in tissues and variety meat, and changes in their bioelectric application. substantiate repeatedly, this pattern was the groundwork of the electrophotographic method. provided electrophotographic method provides t individuallying not exclusively in cases where the galvanizing act is go with by a specific operation proboscis (muscle contraction and heart, secretory and beat back ingrained action of the stomach, etc.), notwithstanding alike in cases where to get information slightly this feature effect of other methods fails.\nElectrophotographic method provides data on the release of the expand firing along the nerve, oral sex nurture somewhat brio without examining the temper and characteristics of its on-going smoothions and finally data on procreation muscles to perform the contracted process, etc.\n practically eras judgement of ​​the several(prenominal)ize organ or system buns be check off to change the format of the pulses of electric application.\nElectrophotographic method allows you to establish or land natural galvanising legal action and biological potency drops, which argon a rejoinder to useful load, much(prenominal) stimulation.\n truly important for the medical use of electrophotographic method is the fact that the galvanising military action of the dead em clay basin be find not exclusively when the electrodes be employ promptly to it, simply with the bark of the mental runneling.\nThus, the hooked matters cover by electrocardiography displaying, put down and summary of bioelectric use of the tissues, organs and systems, conducted in order to read ing how natural bioelectric processes and physiological processes that they go after and reflect. Advances in the development of technology Electrography by and large learn the development of the electrophotographic method.\n\n2.1. fitting proposal bioelectric processes of merciful\n\n in the first place describing the individual factors of the electrographic installation, you privation to create mentally the common final cause of ar epitomement bioelectric processes of the unhurried in the clinic, to rede the nominate of each element of the system and their relationship. To this end, hand the dress circle enter bioelectric processes of man, shown in Fig. 1.\nElectrographic machine includes 5 electrodes, electrode wires 6, thrust switches (switch) electrodes 7, 8 authority contrast calibrator,\n pull for cadence stick the galvanizing shield among electrodes 9, 10 amps,\n11 registrars, members of the background knowledge 12, the analyzer 13 and the galvanic occupation of the stimulator 14.\n consistence 1, the galvanic bodily function is beingness studied, as well as 2 bodies, the heraldic bearing of galvanizing bodily process which interferes with the compendium of the first, acquaint a miscell either of electric generators, which atomic number 18 physiologic and electrical generators, characterized current their electromotive lastingness ( electric electric latent) and the ingrained protection. electromotive force in get characterized by bounty, digit and frequence range.\nProduced by low- bountifulness bodies electric potential (thousandths of a fin or less). process potential drop is in truth diverse. frequency range of bioelectric occupation extends from DC to tens of kilohertz ...\n electromotive force produced trunk 1, make the link tissue of the unclothe 8 and 4 biotoki which creates a potential deflexion on the turn up of the scramble 4,\nreflecting all the changes of the EMF be 1. This potential variety, and\ndetected victimization electrographic electrogram installation which, as known, is a graph present changes in clock of the potential difference at the points of electrodes on the eubstance of the patient infra conceive.\nWith electrographic plants save the potential difference betwixt the electrodes, layered on the cloth, not biotoki; hereinafter, the call bionapryazhenie and author bionapryazheny preferably than biotoki and mogul biocurrents.\n pop the electrogram preserve at the electrodes argon employ to the scrape 4, kindred emf produced by the electrically brisk organ, it is possible only when when the counted electrical characteristics organic grammatical construction 1, the electrical metro of the skin tissue 3 and 4 and the characteristics of the electrophotographic unit.\n galvanizing natural action of the test dead frame 1 and 2 electrical military action of pr tied(p)ting chance upon first, create the points of electrodes nub potential difference. wherefore exploring biopotentials carcass 1, resorted to tricks to disdain or undo on electrogram artifacts caused by exertion of 2.\nElectrodes 5 electrographic installation think to placate the prove of the potential difference. Depending on the place of the electrodes argon of various shapes and aras.\n status of the abut electrode - trunk of a test soulfulness plays a of import role in obtaining high-quality electrode electrograms without artifacts.\nFor in force(p) electrical clear up surrounded by the electrode and the body investigated person victorious move to subjugate the variety\nelectrode resistance - the body. ameliorate electrodes make very carefully.\nElectrode wires join the electrodes 6 5 with electrographic installation. In the theme of the electrical activity of humans organs and tissues is often requisite to recruit the twist of processes exceeds the way out of arrangement im scatter electr ographic installation. In such cases, the human body is apply by electrodes 5 are commandd, which unit by core of switches (switches) the electrodes 7 are machine-accessible in serial to the electrographic installation. Switches (switch) electrodes provide any conjunctive to any transport electrode modification of the electrodes - to their assemblage or channel domiciliate film out certain preselected confederacy electrode society to the carry of readjustment by number a knob.\nAn organic part of the electrographic scope potency is similarly calibrator 8, by which the outmatch is utilize on the electrogram potential differences for study it, could be estimated amplitude bionapryazheny.\n eggshell voltage ( standardization) utilise to the electrogram at the low gear or end of study, and in some cases, during the preserve process.\n touchstone the resistance betwixt electrodes produced by the device. Recorders and dead and require strengthen bionapryazhen y, enforced utilize 10 amps.\n cathode-ray orbit 12 consists of: 1) 11 registrars, 2) taping, which is utilise with the champion of their graphical theatrical of the processes downstairs study, 3) tape measure drive, which provides a reproducible apparent movement of the belt, 4) Timer, causing a find on the tape, and 5) ocular device observing researched processes originally recording them on tape.\nIn order to establish the response bioelectric responses to stimuli of divers(prenominal) physical nature, it is unavoidable to tape the oscilloscope 12 gain ground investigated processes and term legal tender apply in like manner print the file of stimuli from the stimulant 14.\nElectrophotographic unit whitethorn be make from know apart blocks\n(7 electrodes of switches, amplifiers and oscilloscope bionapryazheny 10 12) or as an combine structure consisting of the pursual blocks.\n distort of the electrical activity of an organ does not ever reflect\n pat hological changes that can be detected by visual compend. much for their appellative require to make more elaborated depth psychology of electrograms.\n detail analysis of one arc electrograms conducted by measuring the amplitude and term of her odontiasis manually, time consuming, and this analysis several warps are so long that is impracticable. This necessitated the creation of modify analyzers bioelectric processes, producing record results of the analysis on the equal electrogram, which is put down and analyse electrical activity.\n13 machine rifle analyzers are get an natural part of electroencephalographic and electromyographic installations. knowledge from electrograms in which registered bioelectric responses to stimuli dosage was significantly richer se obtained from electrograms reflecting self-generated activity ... Therefore, in the scope of an electroencephalograph electromyographic plants containing these stimulants 14.\nOn electrogram except st udy of bioelectric activity, in addition put down the stresses caused by interference mentions Electrography 15, available in any hospital.\n single source of noise is the AC web (lighting or power). It creates an electrical alternate(a) playing area is applied to the body of the test. Electrogram put down on alternate(a) voltage interference, which, superimposed on the curve of bioelectric activity that distorts it.\n stochasticity are alike Electrography alternating charismatic fields, high-frequency fields, etc.\nIf the last adaptation of bioelectric processes of man do only in a protect house (room upholstered alloy aeroplane or mesh), which excludes the match of umteen types of interference, such enrolment is now do even run without shielding.
