By the way, the blood circulation promoting device A is provided with two antennas 23 and 24, a first antenna and a second antenna.

The first antenna 23 is disposed on the outer peripheral portion of the printed circuit board 10 on the mounting surface side, and is connected to the recharging terminal 20.21.
It has a spiral shape that surrounds it from the outside. The first antennas 23 are formed by a printing technique and are electrically connected to the IC circuit pattern through the through holes 22, respectively. The second antenna 24 is made of an aluminum plate or the like, and is embedded in the inner surface of the cover 3 by an insert method or the like. The antenna 24 is electrically connected to the circuit (oscillation circuit section 33) of the printed circuit board 10 via an antenna connection terminal 19 having elasticity. One or both of the antennas 23, 24 may be integrated into the base 2.

These antennas 23, 24 are constructed on the circuit shown in FIG. In other words, the blood circulation promoting device A includes a charging voltage detection circuit 31 and an operation control circuit section 32, and both of these circuits 3
1.32 controls the oscillation circuit section 33 to generate the antenna 23.

When charging is started from the dry battery (charging power supply section) 35 through the contact terminals 36.37 and charging terminals 20.21, the operation control circuit section 32 instructs the charging indicator lamp 34 to turn on, and turns on the lamp 79. The user is informed that charging is completed by turning off the light. By the way, the antenna 23.
24 are each independently connected to the oscillation circuit section 33, and a phase adjustment circuit section 38, which is the phase adjustment circuit component 13a, is connected to the oscillation circuit section 33. can be adjusted from the outside using an operating knob (crown) 39 provided protruding from the unit case 1. The operation knob 39 is inserted through a hole 40 of the cover 3 and sealed with an O-ring 41.The blood circulation promoting device A is a donut-shaped mounting made of breathable polyurethane material. The member 42 allows it to be attached to the skin surface removably and replaceably.

Each time the operating knob 39 is pressed one side, the timing of generating the electromagnetic wave output is adjusted to be shifted by a certain amount. This electromagnetic wave output is based on the output waveform oscillated from the oscillation circuit section 33, and examples of patterns in which the output waveform of the electromagnetic wave is changed and adjusted are shown in FIGS. 6(a) to 6(c). In the figure, S+ is the output waveform of the electromagnetic wave from the first antenna 23, S is the output waveform from the second antenna 24, and S is the combined output waveform. to C), the first and second antennas 23
The output waveforms from 24 are all the same, but each has a fixed output state from the first antenna (S,).
23, the oscillation timing of the second antenna (S, ) 24 is changed. <8) in the same figure means that the oscillation timing of the second antenna (S,) 24 is the same as that of the first antenna (S,).
23. That is, both oscillation waveforms Sl,
The phase angle φ=0° between Ss. As a result, the combined output waveform S becomes a simple combination of the output waveforms from both antennas 23 and 24. Note that in the composite output waveform, T represents the period and t represents the oscillation period.

In the pattern shown in FIG. 6('b), the output from the second antenna 24 is shifted by a phase angle φ=90° with respect to the output state from the fixed first antenna 23. As a result, the synthesized output waveform S is not in a large output state as shown in FIG. 2(a), but is in a slightly smaller output state. Note that, as shown in FIG. 3C, when the oscillation timings of the first antenna 23 and the second antenna 24 are shifted by a phase angle φ=180°, the combined output becomes O. This means that depending on how the operating knob 39 is operated, the same knob 39 can also be used as an ON/OFF switch.

In addition, in the above embodiment, a case with two antennas was explained for ease of understanding, but it can be implemented in the same way for a case with three or more antennas. In this case, the output waveform from the antenna including the frequency By changing and composing the images in various ways, a greater variety of output states can be obtained.

Note that a normal type battery may be used instead of the rechargeable battery.

As described above, the blood circulation promoting device according to the present invention is provided with a plurality of antennas, and the oscillation circuit section is capable of adjusting the generation timing of the electromagnetic wave output output from at least one of the plurality of antennas. Since the phase adjustment circuit section is connected, the state in which the electromagnetic field acts on the application site can be freely changed according to the user's preference, and it can be adjusted to suit the user's individual therapeutic goals. The most suitable electromagnetic field output enables effective treatment of the affected area. As shown in the above embodiment, if a plurality of antennas are provided separately on a printed circuit board and a cover, the blood circulation promoting device can be made thinner, and even more antennas can be provided.

In addition, in FIGS. 7 and 8, the antenna 45°46 is
A layer of film 47 arranged parallel to each other is interposed between the printed circuit board 10 and the base 2, and the terminals at the beginning and end of winding of these antennas 45 and 46 are connected to the printed circuit board. The printed circuit board 1 is pressed onto the printed circuit board 10.
0 is electrically connected to the circuit section above. It can also be configured as shown in FIG. What you see in the figure are two antennas 51 and 52.
This is an embodiment in which the wires are arranged on the printed circuit board 50 so as to be spirally wound in the same direction.

This is effective in making the blood circulation promoting device thinner, and also allows the antenna to be closer to the attachment site, allowing electromagnetic waves to act more effectively on the affected area.
