[Problem to be solved by the invention]

However, in such wireless low frequency treatment devices,
As the antenna 21 in the casing 3 of the treatment element 2, a loop antenna is usually formed inside or on the surface of the casing 3 of the treatment element 2, and is electrically connected to the receiving circuit 22.

Therefore, since the antenna 21 is close to each circuit within the housing 3, the influence of the circuits on the characteristics of the antenna 21 is large. Further, since the antenna 21 is formed inside or on the surface of the housing 3 of the treatment element 2, the size of the antenna 21 is limited, and there is a problem that antenna gain cannot be obtained.

The present invention has been made in view of the above points, and an object thereof is to provide a wireless low frequency treatment device with improved antenna efficiency.

In a treatment element of a wireless low frequency treatment device consisting of a housing for storing the electrode and the antenna,
It is characterized in that it is formed on a holding plate separated from the housing, and the holding plate is connected to the housing, and further, the holding plate and the housing can be connected to each other in a detachable manner. This is characterized by the fact that the

[Effect]

In the present invention, the casing that houses the circuit section of the treatment element and the holding plate on which the antenna and electrodes are formed are formed separately, and since the distance between the circuit section and the antenna is large, the circuit can be attached to the antenna. In addition, the shape and size of the antenna are no longer limited by the casing, improving antenna efficiency.Furthermore, the casing and the holding plate can be freely attached and detached using an attachment/detachment button. Therefore, the antenna and electrodes can be easily replaced.

Reference numeral 3 denotes a bowl-shaped casing, which houses circuits such as a receiving circuit 22, a control circuit 23, a booster circuit 24, a pulse discharge circuit 25, and a power supply circuit 26. The operation of each of the circuits described above is the same as that described in the [Prior Art] section, so a description thereof will be omitted here.

4 is a holding plate made of a circular insulator. The retaining plate 4 is
It is separated from the housing 3, and on one surface, a circular loop antenna 21a is formed near the outer periphery, and semicircular electrodes A and B are formed inside the loop antenna 21a. The loop antenna 21a and the electrodes A and B are formed by pasting a metal foil such as copper foil on the holding plate 4, or by etching or the like. A gel-like conductive adhesive 5 is closely formed on the upper surfaces of the electrodes A and B, and the conductive adhesive 5 is used to adhere them to the human body. Reference numerals 6a to 6d are attachment/detachment buttons, which mechanically connect the housing 3 and the holding plate 4, and connect the side of the holding plate 4 on which the antenna 21a and the electrodes A and B are not formed to the end face of the housing 3. They are facing each other. Moreover, the attachment/detachment buttons 68 to 6d also have the function of electrical connection. That is, the attachment/detachment buttons 6a and 6b are connected to the loop antenna 21.

The holding plate 4 is the antenna 21b.
It is attached to the housing 3 using the attachment/detachment buttons 6a to 6C so that the side surface faces the end face of the housing 3.

In addition, in the above embodiment, antennas 21 and 21 are connected to the housing 3 in which each circuit is built.
b and the holding plate 4 on which the electrodes A and B are formed are removably connected, so when changing the shape of the antenna 21.21b and the electrodes A and B, the holding plate 4 is connected to the holding plate 4 using the attaching/detachable buttons 6a to 6.
