Abstract

A life point stimulator characterized by: the stimulator includes a means for detecting a change in skin resistance between the 1 st and 2 nd electrodes, and a means for stimulating the skin between the 1 st and 2 nd electrodes when the change in resistance is detected.

Description

The utility model relates to a life point (acupuncture point) detection and stimulation device, in particular to a life point stimulator which detects the life point of a human body and can give appropriate stimulation to the life point.

For a long time, detecting the vital points of the human body is a difficult thing for ordinary people, which requires professional knowledge, otherwise it can only rely on intuitive touch. On the other hand, when the life point is touched, if the life point is properly stimulated, it is beneficial to eliminate fatigue, relieve tension, and improve health. This is well known. And the device for stimulating the vital point with appropriate voltage and current has been described in a book called Electro-acupuncture Primer, which was written by Fritz Wcrner in 1979. , Medizinisch Literarisohe Verlagsgesell-schaft mbH Veiten, 1979). The devices disclosed in the above materials are relatively expensive, complicated in structure, heavy in equipment, etc., and need trained personnel to operate. In addition, it is very difficult for an untrained person to determine the location of the life point of the human body, so a trained person is needed, at least an untrained person can roughly find out the life point.

Another drawback of the prior art devices is that they require two separate electrodes, one of which must be held by the person being treated and the other held and manipulated by the operator operating the device. This creates a very embarrassing situation when the healer himself operates the machine, especially if he has to treat his own hand. At this time, the therapist himself needs to hold two electrodes, so that the treatment cannot be performed at all, and therefore, the prior device is difficult to use.

Accordingly, there is a need for a simple hand-held vital point stimulator that can detect human vital points very easily and reliably without requiring the user to hold electrodes in both hands while treating himself.

The device of the present invention provides an easy-to-use hand-held vital point stimulator which allows the user to self-medicate. The vital point stimulator includes a hand-held housing with a pair of coaxial electrodes positioned at one end for contact with the skin and coupled thereto with circuitry that detects a drop in electrical resistance on the skin , so as to distinguish the life point. The circuit also includes a pulse generator, which applies a voltage to the identified vital point through the coaxial electrode, so as to stimulate the vital point.

first embodiment

Fig. 1, Fig. 2 are the structural diagrams of the vital point stimulator of the present invention, and in the figure, numeral 1 represents the shell of vital point stimulator, and it is elongated steel shape, between the center electrode 2a of its one end and insulator 4 In between, a ring electrode 2b surrounding the center electrode 2a is installed, thereby forming the life point sensor 2 . Each electrode is made of metal such as stainless steel respectively, and its diameter is 2～6 millimeters respectively. Also, the electrodes 2a, 2b constitute a pair of unit electrodes, which are very close to each other.

The central electrode 2a is connected to an integrated circuit (integrated circuit) 5 containing a DC amplifier (DC amPlifier) through a spring contact 8 and a wire 10. And the ring electrode 2b is also connected to the integrated circuit 5 through the wire 11 as well. The integrated circuit is powered by a power supply 7, and its output terminal is connected to a speaker or a light source. In the integrated circuit 5, a display 13 composed of a plurality of light emitting diodes (dicde) 13a-13c is provided. Display 13 is to represent the resistance between electrodes 2a, 2b. When the resistance is large, the number of light-emitting diodes is not much, and as the resistance becomes smaller, the left end light-emitting diode 13a is just gradually lit. It is also possible to turn on all lights at the beginning, and turn off the lights sequentially as the life points are stimulated.

The electrodes 2a, 2b are connected to a pulse generator 12, and the pulse generator 12 generates pulses in the electrodes 2a, 2b through the switch 3 arranged outside. Assume that the pulse generator 12 is composed of two transformers T ₁ and T ₂ , transistor Q ₁ , capacitor C ₁ and two diodes D ₁ and D ₂ as shown in FIG. 4 .

Integrated circuit 5, power supply 7, speaker 6, pulse generator 12, etc. are placed inside the housing in Figure 1, and the sound of the speaker is transmitted to the outside by the integrated circuit.

In such a configuration, the housing 1 can be held by hand, and the sensor 2 can be brought into contact with the skin of the human body to detect vital points. A current of about 0.2 microamperes is applied to the skin of the human body through the electrodes 2a and 2b. When the electrodes 2a and 2b detect the vital points of the human body, since the resistance between the electrodes becomes smaller (for example, from about 100 megohm to about 100 kilohm), the change in resistance makes the integrated circuit 5 work, and the 6 is expressed with sound, and is also displayed with digits on the display 13 at the same time. The operator operates the switch 3 attached to the side of the casing 1 based on the displayed result.

When the switch 3 is operated, the transistor Q ₁ is energized and the current flows to the primary coil of the transformer T ₁ , and the boosted current flows to the secondary coil, namely the diodes D ₁ , D ₂ and the capacitor C ₁ . Depending on how charged capacitor _C1 is, the diode is either "on" or "closed", thereby causing the secondary winding of transformer _T2 to be pulsed with a predetermined duty ratio. Since the secondary coil of the transformer _T2 is respectively connected to the electrodes 2a and 2b, the pulses are sent to the life points of the human body through the electrodes 2a and 2b to stimulate them. And because the resistor _R2 is a variable resistor, adjusting the resistor can cause the pulse frequency to change, that is, the energy to change, thereby adjusting the amount of stimulation to the life point.

In this way, when the vital point is detected, an electric pulse (pieZo current of about 1 microampere) is generated by operating the switch 3, and flows from the electrodes 2a, 2b to the vital point of the human body, and an appropriate pulse is given to the vital point. stimulation.

2nd embodiment

When the life point is detected, the switch can be automatically driven to apply a voltage between the electrodes.

FIG. 5 shows an embodiment of automatically generating pulses when the vital point is detected. That is, when the life point is detected by the electrodes 2a and 2b, the pulse is amplified by the integrated circuit 5 and displayed on the display 13. At the same time, the comparator (comparatcr) 14 is activated and the switch 3 is turned "on" and the pulse is generated by the circuit in Figure 4 And automatically stimulate life points.

3rd embodiment

Fig. 6 and Fig. 7 are another structure of the life point stimulator of the present invention. The number 21 in Fig. 6 represents the shell, which is in the shape of a finger sack. point. At one end of the housing, between the center electrode 22a and the insulator 24 is installed a life point sensor 22 formed by surrounding the ring electrode 22b. The electrodes are made of stainless steel and other metals as in the above embodiments, and their diameters are about 2-6 mm. And like the first embodiment, they are composed of one unit, and are arranged close to each other, for example, at a closeness of 3 centimeters or less.

Referring to FIG. 8 , the central electrode 22 a is connected to the integrated circuit 25 including the DC amplifier through the spring contact 28 and the wire 30 , while the ring electrode 22 b is also connected to the integrated circuit 25 through the wire 31 . The integrated circuit is powered by a power supply, and its output terminal is connected with a speaker 26 or a light source. A piezoelectric element 23 is connected in parallel between the electrodes, and a light bulb 29 such as an LED (Light Emitting Diode) continues between the lead wire 30 and the piezoelectric element 23 . Integrated circuit 25, power supply 27, loudspeaker 26 etc. are all placed in the lower part of Fig. 6 casing 21, 21a surface, and the sound of loudspeaker then sends out at 21C.

In such a configuration, a finger is inserted into the opening 21b of the housing 21, and the sensor 22 is brought into contact with the skin of the human body to detect vital points. Between the electrodes 22a and 22b, a current of about 0.2 microamps flows. When the electrodes 2a and 2b reach the life point of the human body, since the resistance between the electrodes becomes smaller (for example, from about 100 megohm to 100 kilohm), the resistance change makes the integrated circuit 25 work and is expressed by the speaker 26 with sound come out. Based on this, the operator operates the piezoelectric element 23 attached to the side of the housing. When the piezoelectric element is driven, electric pulses (a piezoelectric current of about 1 microampere) are generated, which flow to the vital points of the human body through the electrodes 22a and 22b, and provide comfortable stimulation to the vital points. At this time LED29 will light up.

In the above-mentioned embodiment, an LED or the like may be used instead of the speaker 26 to implement optical display. It is also possible to automatically drive the piezoelectric element to increase the voltage between the electrodes during detection. In addition, other power sources can be used to supply voltage between the electrodes to replace the piezoelectric element when the vital point is detected.

4th embodiment

As shown in Figure 9, a laser can be used as a stimulus source. Promptly use the equipment that laser power supply 30 and semiconductor laser generator 31 constitute as stimulus source. When the vital point sensor 22 detects the vital point, the switch 33 is turned on manually or automatically to emit laser light. The laser light emitted from the laser generator 31 is guided through the optical fiber 32 between the electrodes 22a, 22b constituting a unit to stimulate vital points. Due to the low output power of the laser, it will not harm the epidermis of the human body. In addition, it is conceivable to use infrared rays, ultrasonic waves, etc. as a stimulus source.

According to the present invention, since the life point can be detected through a low direct current (about 0.2 microamperes), the human body will not feel tingling or unpleasant. Furthermore, since the vital point can be detected and stimulated by the same electrode part, a small and efficient vital point stimulator can be obtained. In addition, since a piezoelectric element or a laser generator is used for stimulating the life point, appropriate electrical stimulation can be given to the life point.

In the various embodiments described above, the electrodes are represented by concentric ring electrodes, but the shape of the electrodes is not limited thereto, and it can have various shapes.

For example, as shown in FIG. 10 , the external electrode 40 may be replaced with an electrode having a plurality of cutouts 40 a at equal intervals. Or arbitrary shapes such as ellipse, rectangle, and triangle as shown in FIGS. 11 to 13 can be made into parallel thin slices as shown in FIG. 14 .

Furthermore, it is not necessary to make the electrodes 40 and 41 concentric, but they may be eccentric. The external electrode 40 and the internal electrode 41 , that is, the anode and the cathode are arranged close to each other, and an arrangement with a distance of 3 centimeters to 1 centimeter or less is ideal.

In each of the above-mentioned embodiments, the relative distance between the electrodes can also be adjusted, that is, as shown in FIG. distance between.

fifth embodiment

Hereinafter, other embodiments of the present invention will be described with reference to FIGS. 16 to 20 . In this embodiment, the elongated casing 100 is made of plastic and is made into a shape that is easy for the user to hold. The clip 111 is attached to the upper side of the casing 100, so that the life-point stimulator can be stored in a pocket and is easy to carry. A pair of light emitting diodes 116 , 117 and switches 112 , 113 , 118 are mounted on the casing 100 . Then a pair of coaxial electrodes 114 and 115 are assembled on the bottom of the casing 100 .

FIG. 20 is a cross-sectional view showing the coaxial electrodes 114 and 115 . Each electrode is separated by an insulating material (including air, etc.), and assembled so as to be in contact with the skin of the human body. The diameter of the central electrode is about 1 mm, and the diameter of the outer electrode 114 is about 4 mm.

FIG. 21 shows a circuit diagram connected to the electrodes 114 and 115 . There is a DC power supply 120 of about 3V, and the power supply 120 can be turned on or off by the switch 112 .

A current of about 0.2 microamperes is passed through the electrodes 114,115. When the electrodes 114, 115 are placed on the vital point, the amplifier 123a is activated due to the decrease in resistance between the two electrodes. The signals from the amplifiers 123a and 123b are transferred to the light-emitting diode 117 to light up the light-emitting diode, and at the same time, the buzzer circuit with the amplifier 123d operates to drive the buzzer 126 . Thus, when a vital point is detected, switch 118 is pressed, driving the pulse generator with transformer _T4 . The pulse amplitude of the pulse generator can be adjusted by switch 113 .

The resistance will change after the life point is stimulated. This change is detected by the amplifier 123C, and the light-emitting diode lights up, indicating that the vital point stimulation has been completed. This operation can also be repeated for other life points.

In this embodiment, the same shape and arrangement of electrodes as shown in FIGS. 10 to 15 can be applied.

As described above, in the vital point stimulator of the present invention, since electrodes for detection and stimulation are shared, the device can be simplified. It becomes small and easy to carry. In addition, both the detection current and the stimulation current are small and do not flow to unnecessary parts, which can have a good effect on human health.

Moreover, in the present invention, since the external electrode and the internal electrode are not separated and form a whole, the operations required for vital point detection and stimulation are very simple.
