Description

Pulse generator by bioelectrical impedance method {EXAMINATOR OF PULSE BASED ON BIOELECTRICAL IMPEDANCE ANALYSIS}

The present invention relates to a pulsator by the bioelectrical impedance method, and more particularly, by applying a current to the arm of the subject by the bioelectrical impedance method, the measurer uses the touch of the measurer through a voltage electrode formed at the tip of a finger. The present invention relates to a pulsator using the bioelectrical impedance method, which not only sets an accurate pulse position but also measures a voltage wave between voltage electrodes and measures and displays and stores a pulse wave.

In oriental medicine, the condition of examinee's disease is determined by the pulse of the radial artery of the lumbar circumferential protrusion located in the inner region of the wrist due to pulsation caused by touch. Judging. In this pulsation in oriental medicine, the veins of the villages are divided into three regions of the upper, middle, lower, that is, the village, the tube, and the chuck. A method of grasping the pulse is taken.

The village (chon) refers to the distal side of the artery of the wrist, the vein of the village represents the state of health from the head to the chest of a person. In addition, the tube refers to the middle of the artery and the distal side of the artery, the vein of the canal represents the state of health from the chest to the navel. In addition, the chuck refers to the heart side of the artery and represents a state of health from the navel to the toe.

Conventionally, a device for obtaining arterial pulse waves using a pressure sensor or the like in a human artery and pulsating by corrugation observation is disclosed in Korean Patent Publication No. 93-1873 (1993.02.22).

This patent discloses that the artery is pressurized by the pressing means, the change in the pressure of the artery is measured by the pressure sensor, and the pulse wave required for the pulse is obtained.

By the way, when the pulse, pulse, and pulsation device is set in advance, the position of the chon, tube, chuck is set in advance, the pressure means of the pulse detection device is automatically measured by pressing the radius of the radius of the wrist, Oriental medicine pulsation When the measurement is made by setting the correct position by touch, accurate pulse wave can be obtained and accurate diagnosis can be performed.

However, the conventional pulse wave detection device has a problem in that it is impossible to determine the accuracy of the measurement because the pulse of the subject, the tube, the chuck must be adjusted by measuring the wrist of the subject.

The present invention was created to solve the above problems, and an object of the present invention is to provide a tactile sense of touch through a voltage electrode formed at the tip of a finger after applying a current to an arm of a subject by a bioelectrical impedance method. The present invention provides a pulsator using the bioelectrical impedance method which not only sets an accurate pulsation position but also measures and displays and stores a pulse wave by measuring a voltage change between voltage electrodes.

The bioelectrical impedance method is a safe, inexpensive, and quick method for measuring the electrical resistance or electrical conductivity of a human body. A pair of current electrodes and a pair of voltage electrodes are in contact with the human body, and then a pair of current electrodes are used to measure about 1 KHz to 1 MHz. It sends 0.1 ~ 2.0mA of alternating current with frequency and calculates impedance from a pair of voltage electrodes and calculates the impedance of the human body. According to the quantification of body composition such as water, protein, bone and fat, Because the resistance is different, it is widely used for body fat analysis because the body composition can be analyzed when the body resistance is precisely measured. That is, the amount of body fluid, muscle mass, body fat, etc. are calculated using a value of measuring the electrical resistance or electrical impedance of the human body by sending a weak current into the human body and using information such as the height, weight, age, and gender of the user.

And the pulse measuring glove 10 having the first to third voltage electrodes 12, 14, and 16 formed thereon so that the finger of the measurer 2 is inserted and the second to fourth finger tips are provided.

The pulse measuring glove 10 is a thin non-conductive member which is not only able to feel the pulse wave of the subject 5 when the measurer 2 wears the pulse measuring glove 10 and pulsates the subject 5. It must be formed.

In this case, the thin insulator member may be made of PMMA (Ploy Methyl Meth Acrylate) optical resin, PHEMA (Poly Hydroxy Ethyl Meth Acrylate), PVP (Poly Vinyl Pyrrolidone), CAB (Cellulose Acetate Butylate).

In addition, the first to third voltage electrodes 12, 14, 16 of the pulse measuring glove 10 are formed to be insulated from the finger of the measurer 2 so that the voltage value measured by the measurer 2 does not change.
