Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to an electrical stimulator.

[0002]

[Prior art example] A conventional electrical stimulator for a living body is based only on the idea that muscles perform irreversible movements by electrical stimulation. The device that considers the effect of electrical stimulation on the living body is
It doesn't exist yet.

[0003]

Electricity tends to flow in a place where it easily flows even at a high voltage. Therefore, even if electrical stimulation is applied to a living body, a certain electric path is formed. Since he did not flow, he could only exercise the muscles of the electrical pathway.

[0004]

In view of the above, the present invention detects the diastole from the pulse wave detecting means and the pulse wave signal obtained by the pulse wave detecting means, and outputs the electrical stimulation during the diastole. An output unit, a conductor for applying the electrical stimulation output of the output unit to the living body, a clamping means for sandwiching the conductor, further abutting the conductor on the living body, and clamping the periphery of the living body including the conductor. By the band-shaped body provided, the abdominal band, in the state of pressing the abdomen, because the electrical stimulation is applied, there is no longer a state where it is easy for electricity to flow at all times. In addition to being able to give exercise to muscles, blood circulation in the abdomen, which is naturally prone to fat in the living body, is promoted, and exercise of muscles in a wide range is always promoted to promote fat metabolism, thereby achieving slimming. Moreover, since electrical stimulation is applied only during the diastole (the period during which the veins are free to send blood to the heart), the veins are given driving force, and the blood circulation promoting action is significantly improved, so that long-term use is possible without fatigue. It becomes possible, and because it consumes extra energy in the body, it also provides conditions for slimming, such as reducing appetite in half. The body part to which the present invention is applied is mainly the abdomen, but also the legs (thighs), arms, waist, and the like.

The material of the abdominal band (4) is not particularly limited, but since it is in contact with a living body for a long time, a material that does not react with the living body as much as possible is preferable. The tightening means (5) is provided on the abdominal band so that the abdominal band (4) presses the abdominal part as much as possible. Here, the abdominal band is in the shape of a single band, and the surface fasteners are sewn and connected to both ends thereof, respectively, and when the abdominal band (4) is wound around the abdomen, the double-sided fastener is joined, Depending on the joining position, the abdomen is pressed so as to be tightened. Therefore, the tightening means (5) shown here is a planar fastener. In addition, an elastic material may be used for the abdominal band itself, and its shape may be a ring shape. At this time, the tightening means (5) is the abdominal band itself having a stretchable material. Therefore, the pressing means can have any shape and material configuration as long as the strip presses the living body.
