DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an electro-medical apparatus comprising a plurality of electrodes, which are adapted to receive bio-electrical signals emitted by an individual, in correspondence of specific areas of his body and comprising means for collecting data collected by the electrodes, so that said signals could be analyzed and a substantially objective evaluation of the equilibrium of the body functions at the level of said specific areas could be performed.
2. Discussion of the Background
For decades, engineers have attempted to facilitate the analysis and the diagnosis of the human body functions as well as to help physicians in the objective evaluation of the patient's health.
It has been about twenty years since German physicians were able to acquire the bio-electrical signals, which are emitted in correspondence of specific areas of the human body, and so they obtained from these data bio-electrical information of an individual, who is examined by a physician. It is well known that the human body emits electrical signals in correspondence of its specific areas. Said signals, duly picked-up and amplified, allow to translate the signals (microampere, microvolt, ohm, conductance, frequency, etc.) into data, which are related to the more or less normal equilibirum of the examinated individual.
The first apparatuses, which were conceived in Germany, would analyze the bio-electrical state of seven areas of the human body, as well as proceed in the reading of the electrical potential, stimulate the measure area with a 10 Hz. impulse package in order to remeasure the conduttance in that area, to make the passive reading of the (inverse) current discharge, stimulate again the measure area with an inverted current impulses, read again the value of said current and therefore of the electrical potential. Said current was repeated seven times on seven human body areas.
The information, which was collected from the seven analyzed areas, had to to be evaluated according to a substantially objective way from the physician, who had used the bio-medical apparatus. The important fact was made of the method, which allowed to use the bio-electronic information and allowed to make a diagnostic interpretation. Already at the time the collected information should be based on a statistic interpretation, but it was recognized that this information would prove the normality or the abnormality of a certain area of the body, for instance the patient's head.
It should be pointed out that the electromedical apparatuses, which were first manufactured in Germany, were able to give the physician a series of data, which were then translated into graphics. These graphics were rather difficult to decipher, whereby at least some years were necessary for the physician to approximately interpret these data.
The German manufacturers of said apparatuses arrived to a considerable sophistication as far as the electrical data measure in some human body areas is concerned, as well as to involve acupuncture therapies, Chinese medicine, etc. But they limited themselves to substantially decode the electrical data of these measures and to simplify their interpretation.
In the U.S.A. the analysis technique of electrical potentials has been used mainly as encephalograms, sleep state measurement, and so on, but not as bio-functional measures, i.e. the measures, which provide elements for arriving to a certain diagnosis and to say, on the collected data basis, whether a certain organ of the human body is working or not and how much this working departs from a normal state.
Meanwhile it is to be pointed out that said bio-functional measures present a further important advantage, i.e. they can record according to a specific way the health state of an individual and a further analysis, which confirm the same data, should just correspond to the same individual and never to another one.
As for Japan, they just started to develop a similar apparatus and we would likely learn quite soon interestin
