Abstract
The present invention relates to new type heart function instrument electrode specially for digital reconstructed cardiac output instrument. The heart function instrument electrode is dislike to available annular electrode and spot electrode for direct or digital heart function instrument, and includes four types, i. e., forehead electrode, neck electrode, chest electrode and foot electrode.
Description
Technical field:
The present invention relates to a kind of novel heart function instrument electrode, annular electrode and point-like electrode that its direct-type different from the past or digital cardiac function gauge are used, but be exclusively used in the electrode of " digital reconstructing heart output instrument ".It exactly is a kind of heart function instrument electrode.
Background technology:
" digital reconstructing heart output instrument " is the instrument that a kind of cardiac function is checked.Heart is constantly to pulmonary and whole body pump blood, and left and right ventricle and trunk then one relax and one contract constantly, this compression process that relaxes be exactly the heart (Guan) process of intracavity volume-variation.From the physics, one section tube chamber relaxes to contract and causes volumetrical change, the inevitable variation that reflects impedance on electricity.The variation of measuring impedance by the input weak current can obtain the volume-variation value indirectly, sets up the appropriate mathematical model, and the impedance variation value that records from the chest body surface just can calculate cardiac output, and this is feasible in theory.
Twentyth century the forties, abroad the someone has proposed " heart round cylinder impedance model " theory, has begun impedance method and has measured kinemic experiment.1966, American Kubicek etc. utilized cardiac catheterization, has derived a kind of formula of impedance differential map and cardiac output, made " impedance method " enter the stage of being suitable for.Impedance cardiogram is being carried the abundant information of cardiovascular activity.By analyzing and processing, can obtain the of great value result of clinical diagnosis, and easy to detect, good reproducibility, with low cost.Therefore, impedance cardiogram is a kind of ideal, noinvasive triage survey technology with tempting prospect, once occurring having caused that just domestic and international clinical medicine and bio information detect the extensive attention of engineering educational circles.
American scholar Kubicek etc. propose to detect in the impedance cardiogram measurement pattern, and its electrode is an annular electrode, and are in use to now always., a detecting electrode and a parallel neck root that places of exciting electrode, other has two to place the same level of chest xiphoid-process lower edge, name day four-electrode method annular electrode.After have the people to suggest improvements to use circular point-like electrode, but be not widely used.
The 1970s and 1980s in last century, numerous basis and clinical researches show that the impedance cardiogram that the Kubicek method obtains from the chest body surface measurement is common " comprehensively " impedance variation that produces of the left heart, the right heart and chest trunk volume-variation.It includes the information of left and right ventricle, left and right lung blood vessel and the multiple impedance variation of aorta, and they are mixed in together, promptly so-called " shortage uniqueness ".The Kubicek formula is then got well several impedance variation amount as aortal variable quantity with this, after measuring and calculating is come out, regards the output of the left heart as, and this is undemanding in theory.To this, the clinician can not accept certainly, and the state of an illness is judged and the treatment decision-making because it can influence, and might make a serious mistake.
The Kubicek relational expression can not be used for the level diagnosis of heart disease, this with regard to serious restriction its clinical application range.Therefore, from twentyth century the nineties just march toward low ebb from the beginning of, the research of cardiac impedance method gradually with using.The whole world exceedes ten thousand impedance cardiogram instrument and is scrapped processing, comprising surplus the China about 6000.
The original intention of Kubicek formula is to be used for calculating the left ventricle output, the impedance waveform that it adopts four-electrode method to record from body surface, but be the coefficient results of a plurality of tube chamber impedance variation such as left and right ventricle and chest trunk, the information that has wherein comprised a plurality of tube chamber impedance variation, be not the single information of a certain tube chamber impedance variation, so can not be used for positioning analysis.If we can come left and right ventricle, left and right lung blood vessel and aorta impedance variation branch separately from the impedance ripple of body surface record, obtain their impedance variation component, so, the kinemic problem of impedance measurement just can fundamentally be solved.
Originally, the scientist of countries in the world attempts to improve, revise on the Kubicek formula, subsequently, and again at recording electrode and survey position redesign mathematical model and algorithm.Yet after more than 10 year, the final discovery of people has to accept such fact: abandon Kubicek formula and its four-electrode method, other wards off Xi Jing possibly clearly.
How to obtain the left heart, the impedance variation component that the right heart and chest trunk volume-variation produce from body surface? this be electric bioimpedance signal detect in the research field one reach more than 30 year still unresolved, but be the fundamental issue that presses for solution.To this, impedance expert and clinical medicine worker think long and hard invariably both at home and abroad, painstakingly.
It is mathematics and the significant achievement of develop computer software, application in modern age that computer digit is rebuild.Existing multiple examples of many successful in human tissue structure is rebuild, as X line CT, nuclear magnetic resonance, NMR and impedance CT just under study for action etc., they belong to figure (image) and rebuild.And waveform reconstruction is different from image reconstruction, has three lead electrocardiogram to rebuild the report of 12 lead electrocardiogram recently.The impedance component problem that adopts digital reconstruction technology resolved impedance spectroscopy to measure different components in the cardiac output belongs to the waveform reconstruction category, its electrode rest, quantity, electrode slice size, spacing etc., most important to signals collecting, it is calculated by mathematical model and draws in conjunction with Physical Experiment and human experimentation.The electrode that the present invention relates to is used for the electrode special of digital reconstructing heart output instrument just.Large clinical research, 110 routine color doppler ultrasonography comparative studies, and routine isotope ECT comparative study confirms that all electrode of the present invention meets the requirement of digital reconstructing heart output instrument acquired signal fully surplus in the of 30.
Summary of the invention:
Accompanying drawings content of the present invention:
