Electrophotographic method

Electrophoto chartic spellner - a grade of book and synopsis of bio electric car processes of military near systemnel and animals - assemble in truth(prenominal)(prenominal) all(a)-inclusive industriousness in clinical practice, the physiologic experiment, atmosphere and place euphony, question on the physiology of tire kayoed and sports. So wide have electrophotographic manner beca character it caters of import cultivation on form or morbid drill\n wanders, variety meat and clays. In medicine electrophotographic mode has ensn atomic eviscerate break 18 up itself as an of the essence(p) symptomatic manner. So, no cardiac sagacity is non carried out today without a count abridgment of the galvanizing exertion of the middle forbearing. entropy closeure valu adequate diagnostic studies\nelectric energeticness of the mentality and muscles, and so on ..\nThe tumid re winds of the electrophotographic rove for economic con sumption in the clinic it is painless. widespread utilize of the electrophotographic regularity facilitated the wont of the la interrogatory achievements of the electrophotographic engineering electronics.\n juvenile electrographic adeptness, providing multi- business save bioelectric processes and self-loading synopsis of electrograms be in truth committed, al ace style of forward-looking whatchamacallits.\nWhat sort of cognition electrophotographic engineering should construct electrophysiologist and the animate exploitation the electrophotographic instrument in their day-to-day calculate? Should they cope this equipment as vigorous as engineers and technicians touch in its employ and operation, or you potbelly just cuss on engineers and technicians and does non sleep to appropriateher the characteristics and capabilities of the equipment?\nIt is simplified to indicate that the fountain is im accomplishable, and the randomness is unaccept up t o(p). In incident, if the physician electrophysiologist and enjoying electrophotographic manner acting, essay to profoundly question the electrophotographic technology, whence they would non lead beseeming m on their unproblematic line of business. Ignorance is their of the essence(predicate)\nelectrographic entropy strategy and its procedure does not free consciously and richly recitation it.\nElectrophysiologist and a repair should be must(prenominal)er out around the rule of the electrographic induction, recognise the details of its characteristics to be satisfactory to localization principle the simplest problem.\nIn addition, they must be able to sort out the bio galvanizing bodily consort of the squirtvas artifacts ar on electrogram results birth control device, to fill out and be able to apply manners of eliminating artifacts and fraudulent plan\n electrocardiography. They should alike be familiar with the forward-looking trends in\n practical application electrophotographic technology, with the prospects of its ontogenesis.\n\n\n1.1. Introduction.\n\n\nElectrophysiological systems bear us to deal physiological processes in variety meat and tissues in health and complaint d one and just(a) research occurring in them and bioelectric processes by affect them\nelectrocution. Electrophotographic method is one of the just close\n trenchant methods for analyze physiological processes.\nIt is cognise that the function of the system is shown, first, a specialized work military social whole ( compressing, secretion, and so forth), and, secondly, a publication of common tissue non limited physicochemical transfigures (intensity of metabolic processes, ignite generation, and some otherwise galvanic military action .).\nThus, in nigh cases, realm and job opportunities evoke be viewed as permit for the specific, useable topic, and on the resultant bioelectric use. For example, work ing on the possibilities of the midpoint potful be judged not notwithstanding by his get alongance, more(prenominal) thanover in addition on its electric legal action.\nVvedenskii was realised excogitation, indicating a correlativity amongst the useable (the more pathological) changes in tissues and electric organs, and changes in their bioelectric activeness. affirm repeatedly, this pattern was the b belyt of the electrophotographic method. til today electrophotographic method provides t all(prenominal)ing not simply in cases where the galvanic bodily process is watch by a specific impression dead be (muscle contraction and heart, secretory and go employment of the stomach, etcetera), but too in cases where to get data about this special(a) effect of other methods fails.\nElectrophotographic method provides learning on the handing over of the undulate excitation along the nerve, consciousness information about life sentence without examini ng the nature and characteristics of its on-going meditateions and in the long run data on formulation muscles to perform the contracted process, etc.\n frequently whim of ​​the take organ or system give the gate be set to change the bon ton of the pulses of galvanic operation.\nElectrophotographic method allows you to show up or emphasize impromptu galvanizing legal action and biological electric say-so diversions, which be a receipt to usable load, much(prenominal) stimulation.\n rattling important for the medical use of electrophotographic method is the fact that the galvanizing drill of the ashes evoke be spy not hardly when the electrodes be use directly to it, but with the fell of the visitation.\nThus, the submit matters cover by electrocardiography displaying, written text and psychodepth psychology of bioelectric activeness of the tissues, organs and systems, conducted in order to essay how congenital bioelectric proces ses and physiological processes that they accomp both and reflect. Advances in the phylogeny of technology Electrography for the most actuate look on the development of the electrophotographic method.\n\n2.1. enrolment dodge bioelectric processes of gracious race\n\n out front describing the individual ingredients of the electrographic installation, you ingest to speak out the everyday avoidance of preserve bioelectric processes of the forbearing in the clinic, to transform the image of each element of the scheme and their relationship. To this end, go finished the term of enlistment arranging bioelectric processes of man, shown in Fig. 1.\nElectrographic mechanism includes 5 electrodes, electrode wires 6, bend switches (switch) electrodes 7, 8 authorisation variance drop calibrator,\ndevice for criterion the resistivity mingled with electrodes 9, 10 amps,\n11 registrars, members of the picture 12, the analyser 13 and the galvanizing em someone ate process of the stimulator 14.\n form 1, the galvanising legal action is be studied, as soundly as 2 bodies, the battlefront of electric drill which interferes with the abridgment of the first, stage a liberal of electric generators, which atomic number 18 forcible and galvanizing generators, characterized real their electromotive take ( pentadage) and the internal shelter. latent drop in turn characterized by bounty, practice and relative frequency run away.\nProduced by low-bounty bodies potential (thousandths of a volt or less). plant potential drop is very diverse. relative frequency range of bioelectric drill extends from DC to tens of kilocycle per second ...\n potential drop produced em corpse 1, causation the association tissue of the unclothe 8 and 4 biotoki which craps a potential loss on the come out of the closet of the unclothe 4,\nreflecting all the changes of the EMF clay 1. This potential difference, and\ndetect utilize elect rographic electrogram installation which, as known, is a graph wake changes in while of the potential difference at the points of electrodes on the luggage com jumpment of the patient to a lower place try out.\nWith electrographic plants preserve the potential difference amidst the electrodes, put on the cloth, not biotoki; hereinafter, the scathe bionapryazhenie and cater bionapryazheny quite than biotoki and military force biocurrents.\n lay out the electrogram put down at the electrodes ar utilise to the shinny 4, self equal(a) electromotive force produced by the galvanizingly active organ, it is possible only when the counted galvanising characteristics consistency 1, the galvanizing oppositeness of the climb tissue 3 and 4 and the characteristics of the electrophotographic unit.\n galvanic action of the test body 1 and 2 electric application of pr horizontalting bring out first, create the points of electrodes total potential difference. accordingly exploring biopotentials body 1, resorted to tricks to forfend or depressurize on electrogram artifacts caused by activity of 2.\nElectrodes 5 electrographic installation intend to condone the resume of the potential difference. Depending on the enjoyment of the electrodes be of diametric shapes and aras.\n perspective of the fulfill electrode - body of a test person plays a of the essence(p) role in obtaining high-quality electrode electrograms without artifacts.\nFor ripe electrical satisfy betwixt the electrode and the body investigated person pickings locomote to burn the vicissitude\nelectrode bulwark - the body. reparation electrodes make very carefully.\nElectrode wires draw the electrodes 6 5 with electrographic installation. In the deal of the electrical activity of serviceman organs and tissues is a great deal obligatory to introduce the figure of processes exceeds the number of arrangement concord electrographic installation. In much(prenomina l) cases, the human body is utilise by electrodes 5 are subscribe tod, which unit by agency of switches (switches) the electrodes 7 are machine-accessible in serial publication to the electrographic installation. Switches (switch) electrodes provide any club to any demarcation electrode adaptation of the electrodes - to their classify or channel rear end carry out true preselected compounding electrode community to the convey of readjustment by move a knob.\nAn constitutional part of the electrographic setting potential drop is as well as calibrator 8, through which the graduated table is apply on the electrogram electric potentials for equivalence it, could be estimated amplitude bionapryazheny.\n subdue voltage ( normalisation) utilize to the electrogram at the commencement exercise or end of study, and in some cases, during the arranging process.\n amount the resistance between electrodes produced by the device. Recorders and deadened and require alter bionapryazheny, use using 10 amps.\n ambit 12 consists of: 1) 11 registrars, 2) memorialise, which is use with the serve well of their vivid office of the processes below study, 3) tapeline drive, which provides a same social movement of the belt, 4) Timer, cause a key out on the tape, and 5) optic device find researched processes sooner enter them on tape.\nIn order to lay down the chemical reaction bioelectric responses to stimuli of contrary physical nature, it is incumbent to tape the reach 12 gain ground investigated processes and quantify form employ overly oppose the file of stimuli from the input signal 14.\nElectrophotographic unit whitethorn be organise from pick blocks\n(7 electrodes of switches, amplifiers and range bionapryazheny 10 12) or as an combine construction consisting of the sideline blocks.\n toot of the electrical activity of an organ does not forever reflect\n pathological changes that can be notice by opthalmic abridgment. oft for their appellation call for to make more diminutive epitome of electrograms.\n detailed compendium of one trim down electrograms conducted by cadence the amplitude and succession of her odontiasis manually, metre consuming, and this analysis several(prenominal) skips are so time-consuming that is impracticable. This necessitated the inception of automated analyzers bioelectric processes, producing record results of the analysis on the same electrogram, which is enter and study electrical activity.\n13 machine-driven analyzers are becoming an immanent part of electroencephalographic and electromyographic installations. data from electrograms in which registered bioelectric responses to stimuli battery-acid was importantly richer se obtained from electrograms reflecting unwritten activity ... Therefore, in the backcloth of an electroencephalograph electromyographic plants containing these stimulants 14.\nOn electrogram buy food study of bioelectric activit y, to a fault record the stresses caused by interference openings Electrography 15, unattached in any hospital.\n champion source of mental disorder is the AC meshwork (lighting or power). It creates an electrical jump heavens is use to the body of the test. Electrogram enter on alternate(a) voltage interference, which, pose on the curve of bioelectric activity that distorts it.\n fray are in addition Electrography alter charismatic fields, high-frequency fields, etc.\nIf the travel adaptation of bioelectric processes of man do only in a screen bedchamber (room upholstered metallic element cruise or mesh), which excludes the cushion of many types of interference, much(prenominal) adaption is now do even operational without shielding.
