Description

[Detailed description of the invention] This invention generates a low frequency therapeutic electrical waveform,
The present invention relates to a low-frequency treatment device that supplies stimulation current to treatment points on the human body via hydrous treatment electrodes.

Some conventional low-frequency treatment devices have a structure in which an electronic circuit for generating a low-frequency electric waveform, a battery power source for driving the electronic circuit, an output electrode, and a treatment electrode are integrated into a housing. However, these low-frequency treatment devices have a rectangular or rod-shaped housing with an output electrode attached to the tip, and the part that the user holds with his hand and the electrode part are used for different purposes. They are placed at separate locations. In other words, if we compare the shape that is easy to hold in the hand with the area and spacing conditions of the pair of output electrodes, we find that in order to make it easy to hold in the hand, we need a thin, easy-to-grip rod-like shape, and as a result, the output electrode The area was getting smaller due to its shape. Therefore, concentration of the therapeutic current occurred, and the therapeutic current stimulation became large. This low-frequency treatment device also had the disadvantage that it was difficult to find the treatment point on the human body due to the spacing and arrangement of the output electrodes or the shape of the treatment device.

The present invention has been devised to eliminate the above-mentioned conventional drawbacks, and the present invention will be explained below based on drawings showing embodiments thereof. In Figure 1, 1,

is a knob for adjusting the output of the electronic circuit 4 provided on the printed circuit board 3. The printed circuit board 3 is sandwiched and fixed between an upper housing 1 and a lower housing 2 that constitute a circular thin housing, and an output adjustment knob 8 is connected to an output regulator 9. engaged and integrated.

The upper casing 1 and the lower casing 2 sandwich the printed circuit board 3 therebetween and are fixed in a watertight manner by tightening them with screws 11 via a rubber ring 10. Furthermore, a large-diameter rubber ring (not shown) is inserted into the outer periphery of the fitting between the upper casing 1 and the lower casing 2 to prevent water from entering from the side surfaces of the casings.

Figure 2 shows the outer components of the integrated thin case, with reference numerals 12 and 12' representing a pair of output electrodes, and output coupling lines 13 and 13' being connected to the back side of the output electrodes. . Reference numerals 14 and 14' denote a pair of hydrous treatment electrodes, which are made of polyvinyl formal resin and are pressed against the output electrodes 12 and 12', respectively. Reference numeral 15 denotes an electrode holding member for holding the hydrous treatment electrodes 14, 14', and this electrode holding member 15 is provided with a pair of windows 16, 16' for exposing the hydrous treatment electrodes 14, 14'. Protrusions 17, 17' are provided at opposing positions on the surface. Furthermore, peripheral frame-shaped ribs 18, 18' are provided on the outer circumference of the lower casing 2 constituting the circular thin casing, and these ribs 18, 18' are provided with the ribs 18, 18' provided on the electrode holding member 15. Cut holes 19, 19' are provided in which the protrusions 17, 17' are engaged. Further, the lower housing 2 is provided with holes 20, 20' through which the output coupling lines 13, 13' of the output electrodes 12, 12' are passed.

The output electrodes 12, 12' are connected to the output coupling line 1
3, 13' are passed through the holes 20, 20' of the lower housing 2, and the ends of the output coupling lines 13, 13' are coupled to the output of the printed circuit board 3 having the electronic circuit 4. Further, the output electrodes 12, 12' are inserted into the inner side of the peripheral frame-shaped ribs 18, 18' provided on the lower housing 2, and the holes 22, 22 are inserted into the pins 21, 21' provided on the lower housing 2. ', and also adhered to the lower housing 2 with adhesive to open the holes 20, 2 of the lower housing 2.
0' is sealed. The output electrodes 12, 12' bonded to the lower housing 2 are provided with a hydrous treatment electrode 1 from the outside.
4 and 14' are pressed against each other and electrically connected,
The electrode holding member 15 holds the hydrous treatment electrodes 14, 14' by fitting the protrusions 17, 17' into the cut holes 19, 19'.

With the above structure, the hydrous treatment electrode 1 pressed against the output electrodes 12, 12'
Even if moisture leaks from 4, 14' when the treatment device is in use, the outside of the lower housing 2 is sealed by the output electrodes 12, 12', so moisture will not leak inside the lower housing 2. This can prevent them from entering.
Furthermore, since the electrode holding member 15 is detachably attached to the lower housing 2, the hydrous treatment electrodes 14, 14' pressed against the output electrodes 12, 12',
It is very easy to replace or clean it.

On the other hand, as shown in FIG.
is provided to separate leakage water from the hydrous treatment electrodes 14, 14'. This can prevent leakage current between the electrodes due to the presence of leakage water between the hydrous treatment electrodes 14, 14'.

FIG. 4 shows the lower casing 2 at different perspective angles.
The cut holes 19, 19' in which the protrusions 17, 17' of the electrode holding member 15 engage are clearly shown.

As described above, according to the present invention, a printed circuit board having an electronic circuit, a pair of output electrodes, a driving battery power source, and a pair of hydrous treatment electrodes are integrated into a thin circular casing. can be made extremely compact, and the pair of output electrodes and hydrous treatment electrodes can be provided on the circular surface of the housing, which has a large surface area. The problem of increased therapeutic current stimulation is eliminated, and even if water leaks from the hydrous treatment electrode, the structure prevents water from entering the inside of the casing, allowing the electronic circuit to work in a stable state at all times. It is something that can be done.
