Description

The invention relates to medical technology, mainly to devices for locating acupuncture points.

The purpose of the invention is to obtain a graphic image of a body region with acupuncture points.

FIG. 1 shows a functional diagram of the device; in fig. 2 is a kinematic diagram of the connection of a probe with potentiometers using polar coordinates; in fig. 3 - the same, when using Cartesian coordinates.

The device comprises a frame 1, with which a potentiometer 2 is rigidly connected, connected by a movable electrode by means of a traverse 3 to the case of potentiometer 4, and the movable electrode of the latter by means of a traverse 5 is connected to a metal probe 6 through a series-connected power source 7 and a variable resistor 8 connected to common | Bus 9. One of the stationary electrodes of potentiometers 2 and 4 is connected to the common bus 9, and their second stationary electrodes are connected to different terminals of the additional power source 10. The movable electrode of the potentiometer 2 is connected to the first coordinate terminal 11 of the coordinator 12, the movable electrode of the potentiometer 4 is connected to the second coordinated terminal 13 of the coordinator 12, and the recorder 14 of the coordinator 12 using the cross bar 15 with the movable spring-loaded core 16 of the electromagnet 17. One of the electrodes of the coil 18 The electromagnet 17 is connected to the common bus 9, and the second to the common point between the power source 7 and the variable resistor 8, and the common bus 9 to the passive electrode placed on the palmar surface of the hand 19 uyema.

The device works as follows.

The voltage of the power supply source 10 is distributed between potentiometers 2 and 4. With a high resistance of the input circuits of the coordinator 12, the current through potentiometers 2 and .4 is constant. The voltage between the movable electrodes of potentiometers 2 and 4 and the common bus 9 is determined by their position.

Faith 3 and 5 is determined by the position of the probe 6 in the cavity of frame 1.

Frame 1 (FIG. 1) is fixed above the area of the human body to be examined, for example, above the auricle. The common tire 9 is connected to the palmar surface of the brush 19. Then the instrument is calibrated. For this purpose, the shoop 6 is installed on the acupuncture point and using an alternating resistor 8 a current is picked up through an electromagnet 17 of such magnitude that the core 16 of the electromagnet 17 moves, which through the yoke 15 acts on the recorder 14 of the coordinate recorder 12, fixing the last position of the acupunct - round point. Then the probe 6 is shifted to the body surface area where there is no acupuncture point, and with the help of a variable resistor 8, the current through the coil 18 of the electromagnet 17 is reduced until the core 16 returns to its original position. When moving the probe 6, which is rigidly connected by means of the crosspiece 5 with the movable electrode of the potentiometer 4, this electrode moves, causing the potential of the second coordinate terminal 13 of the coordinate system 12 to change, which causes the recorder 14 to move in the direction of the probe 6 movement. that the case of the potentiometer 4 is rigidly connected with the help of a cross beam 3 with the movable electrode of the potentiometer 2, when moving the probe 6, the movable electrode of the potentiometer 2 moves, as a result of which the potential changes The first coordinate terminal of the coordinate recorder 12, which causes proportional movement of the recorder 14. When the probe 6 hits the area of the acupuncture point, the electromagnet 17 is activated and its position is fixed on the coordinator 12. The possibility of scaling the recording by amplifying the signal in the coordinator 12 allows an increase in the scale of the radiated field.

1 is magnified at the current calibration stage with a variable resistor 8, it is possible to contour the area under study with registration of characteristic surface areas.

By changing the direction of the current specified by the power supply 7 and sequentially testing the examined acupuncture points, it is possible to determine and graphically objectify conductivity with acupuncture points for currents of opposite polarity, i.e. symmetry or asymmetry of conductivity.

The device allows you to find acupuncture points, build large-scale topographic maps of the studied areas of the body, determine the possible migration of points, study the asymmetry of conductivity, change the scale of topographic maps of acupuncture points.
