KR900007215B1 - Electronic pulse feeling device for practice of diagnosis in oriental medicine - Google Patents

Abstract

The device assists a medical practitioner in sensing and categorizing various pulses found at different loctions in the human body. The piezo-electric sensors (10) are used to duplicate the kinetic sensations which have been in the past sensed by the human fingers. The sensors are located on the human body undergoing diagnosis along the radial artery at point corresponding to the chon, kwon, and chuk locations which have been described in old chinese medical books. The sensed signals are amplified, differenctiated and integrated two times to get the pulse. The pulses are passed through the wave filter to get the easily readable wave forms.

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a pulse recording apparatus in oriental medicine, and more particularly to a pulse wave converting apparatus of pulse hydroxy.

Functional tests of the human body's purifying organs include blood pressure monitors, electrocardiograms and clesmo-graphics in Western medicine, and in oriental medicine, pulse recording devices are the first in Korean Patent No. 4986 (May 14, 1976) and the United States. Patent No. 4,066,066 (August 1, 1978) and Japanese Patent No. 1,164859 (August 26, 1983) are known.

They can be seen that they have in common that the physiological changes of the circulatory organs are visually expressed by electronic equipment.

In other words, electrocardiogram, plesmographic or pulse recording device records natural signals generated from the human body, especially circulatory system through a series of amplification circuits, and analyzes the recorded graph form. It is used.

Such an electrocardiogram is a machine that judges the function of the heart by recording the potential difference generated by the heartbeat, and has secured a lot of data that is already widely used, but the electrocardiogram is a clinical test and the result is not a judgment of heart disease. Therefore, the ECG reading has a problem that must be parallel to the clinical findings.

Plessismographic, on the other hand, is a newer study that focuses on the amount of blood flow along the capillaries in order to overcome the limitations of diagnostics on electrocardiograms. Acceleration Plesigrams are recorded to enable the diagnosis of some diseases centered only on adult diseases. (Reference US Patent No. 3,881,481 No. 3,920,004 No. 4,154,238 No. 4,432,374) In addition, the above-described registered patent (Korean Patent No. 4986, US No. 4,066,066, and Japanese No. 1,164,859) is a conventional pulsisto In the circuit used in the gram, the sensing method is recorded in the vibration waveform by the piezoelectric effect according to the pulsed part and interpreted according to the early system of Oriental medicine to diagnose various diseases. have.

As mentioned above, the plesmographic and pulse record are the same in terms of the diagnosis of diseases through the circulatory system, but the type of graph is very simple, so it is a relative interpretation data that sets and compares several basic waveforms. The present invention has been conceived since it cannot be achieved.

Therefore, the present invention aims to modulate the pulse wave to obtain the absolute data in oriental medicine by modifying the basicization based on such a theory. In other words, the basic waveform types are clearly distinguished, and even if the beginners encounter them, the result is easy to distinguish.

As already explained, the diagnosis of diseases according to the state of the circulatory system is very important regardless of the east and west, and it is not necessary to explain. For example, the diagnosis of oriental medicine in oriental medicine is not found anywhere else in the book. You can easily get a description of pulsation.

The basic principle of pulsation seen above is to detect the waveform of the pulsation generated by breathing and heartbeat and record it as a graph.

This is a form in which one more cause of respiration is added as compared with the measurement of the potential change due to the heartbeat of the Western medicine or the measurement of the blood flow in the capillaries according to the heartbeat.

Therefore, the pulse waves are unique in their shape and are important data for the classification of Eastern medical blood types.

The circulatory system in the living body is a kind of closed circuit, which is a method of detecting the circadian rhythm that is constantly being circulated according to the life activities. Potential changes, blood flow, and pulsating wavelengths only need to check each repeated rhythm by sensing. Comparing waveforms can be tricky.

Furthermore, in the sense of positive and negative decline in Qi in Oriental medicine, we are comparing positive and negative. To display this on the graph, the rise of Q is positive, and the decline of Q is negative. It should be able to represent the position of.

Therefore, the rise and fall of the group is divided into (+) direction and (-) direction by defining the central axis according to the principle of yin and yang, which is the same as the principle of differential.

Therefore, it was possible to confirm by experiment that the micro wave changes occurring in the human body can be expressed in the position of yin and yang by differential expression. It is now possible to accurately interpret the pulse wave.

Therefore, in order to discriminate by a more complicated graph than by a simplified graph by observing a more complicated change of the human body, the present invention not only determines the output signal as a positive and negative position by passing an extreme band filter, but also Its unique form makes it possible to interpret its meaning, enabling accurate diagnosis.

In other words, it is possible to record 28 veins, which are the basis for the pulse, from the basal vein of 8 yo on the basis of the flat vein, the condyle, and the vein showing yin and yang in oriental medicine. do.
