Description

[Detailed Description of the Invention] This invention relates to an electric stimulator using a piezoelectric unit.

Conventionally, many electric stimulators have been proposed, such as those described in Japanese Utility Model Application Publication No. 47-985, etc.
In both cases, a high voltage of tens of thousands of volts generated by a piezoelectric element is discharged directly to the affected area using a needle-shaped electrode, so the stimulation is not too strong and the strength of stimulation cannot be adjusted, so it is recommended to use it in moderation. It had the disadvantage that stimulation could not be applied, and furthermore, it was difficult to apply stimulation to a predetermined acupuncture point with an area of 0.2 mm ² .

The object of this invention is to provide an electric stimulator that can overcome the above-mentioned drawbacks.

The drawings illustrate embodiments of the invention.

Reference numeral 1 denotes a hollow holding cylinder, into which the rear end of a conductive lid 3 is screwed. A piezoelectric unit 4 consisting of A conductor 6 protrudes from the front end of the piezoelectric element 5, and the tip of the conductor 6 forms a discharge electrode 2 facing the bottom surface of the lid 3. The rear end of the impact member 8, which is inserted into the piezoelectric element 5 and is constantly biased outward (rightward in FIGS. 1 and 2), touches the rear end of the holding cylinder 1. It comes into contact with the tip of a pressing member 9 installed movably along the axial direction, and this pressing member 9 touches the step part 10.
It engages with the opening flange 11 of the cylindrical body 1 to prevent it from flying out.

In the above-mentioned device, the lid body 3 is pressed against the human body using the holding cylinder 1, and the head of the pressing member 9 is pressed against the human body.
When the impact member 8 is pressed against the biasing force,
The impact member 8 impacts the piezoelectric element 5, and the piezoelectric element 5
A high voltage is instantaneously generated from the square electrode 2, which causes a discharge toward the bottom surface of the lid 3, and the lid 3 generates a voltage due to the discharge, and the surface of the lid 3 stimulates the human body. Therefore, by increasing the area of the lid body 3, the area can be reduced.
Stimulation can be easily applied to a predetermined acupoint as small as 0.2 mm ² . Note that the holding cylinder 1 is made of a defective conductor, and the holding ring 12 of the conductor 6 and the holding ring 13 of the lid body 3 are
are also made of similar materials.

In the case of the above-mentioned device, if you want to give strong stimulation, screw the lid 3 deeply so that the terminal 2 is almost in contact with the bottom of the lid 3, as shown in Figure 1. If you want to weaken the stimulation, screw the lid 3 shallowly so that the terminal 2 is separated from the bottom of the lid 3, as shown in FIG. By doing so, it is possible to provide moderate stimulation to the affected area.

This idea involves fitting an annular holding member to the outside of the tip of the holding cylinder so that it can move in the axial direction, and placing a conductive lid on the tip of the holding member with its bottom facing the discharge electrode and applying it to the affected area. Because the piezoelectric unit has a high voltage generated by the piezoelectric unit, a discharge is generated from the discharge electrode toward the bottom of the conductive lid, and the discharge stimulates the affected area from the surface of the conductive lid. Therefore, the intensity of stimulation can be adjusted by adjusting the distance between the discharge electrode and the bottom surface. In addition, by making the surface of the conductive lid large, it is possible to easily stimulate a specific pressure point with a small surface electrode, and furthermore, it is possible to easily stimulate a specific pressure point even from over clothes. It has the effect of
