Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an ultrasonic treatment device, and an object thereof is to provide an ultrasonic treatment device that can improve therapeutic effects and reduce power loss.

Hereinafter, an embodiment embodying the present invention will be described with reference to the drawings. In the drawing, 1 is a bathtub, 2 is an ultrasonic generation nozzle attached to the side surface 1a of the bathtub 1, and is fixed to the side surface 1a. It consists of a nozzle body 3, a foaming nozzle 4 screwed onto the tip of the nozzle body 3, and an air suction pipe 5 communicating with the nozzle body 3. ■It forms.

Reference numeral 6 denotes a pump which is disposed on the side of the bathtub 1 and is operated by a motor 7. Its suction port and bathtub 1 are connected through a pipe line 8, and its discharge port and the nozzle body 3 are connected through a pipe line 9. It is connected by

In the ultrasonic treatment device described above, the motor 7 is started to operate the pump 6, and the water in the bathtub 1 is transferred to the pipe 8 and the pump 6.
When the water is injected from the ejection hole 3a of the nozzle body 3 through the conduit 9, air is sucked into the space V from the air suction pipe 5 according to the principle of atomization, and water is mixed with the air from the ejection hole 4a of the foaming nozzle 4. , and are emitted into the bathtub 1 as a group of ultrasonic bubbles.

Now, in the apparatus having the above structure, the applicant injects water from the nozzle body 3 at a predetermined pressure (1 to 2 kq,/cl) so that the volumetric mixing ratio of water and air is 6:4. An experiment was conducted to measure how sound waves are generated as follows. An underwater microphone 10 is placed in the bathtub 1 facing the generation nozzle 2, and
After the detection signal from the microphone 1o is amplified by the preamplifier 11,
The resultant signal was re-amplified by the amplifier 13 connected to 2, and further recorded by the recorder 14, resulting in the results shown in the graph of FIG. As a result, approximately 40,000 to 70,000
It has been found that high sound pressure (approximately 20 decibels dB) with excellent therapeutic effects is generated in the ultrasonic range A of 0 hertz (I(7,)).

On the other hand, in the above-mentioned experiment, it is desirable that the volumetric mixing ratio of water and air be approximately 6:4, but this was obtained through various experiments with varying mixing ratios;
The mixing ratio may be 4.3 to 3.7 to air to 6.3.

Based on the above experimental results, the applicant decided to file an application for an ultrasonic treatment device that generates ultrasonic waves in the area A. A superhigh wave generating nozzle 2 is arranged, which is composed of an air suction pipe 5 and has a space (2) inside, and a means for supplying water is connected to the nozzle body 3, so that the volumetric mixing ratio of water and air is adjusted. 5.7-6J: The structure generates ultrasonic waves at approximately 40,000-70,000 Hz per second under 4°8-3.7, improving the therapeutic effect and reducing unnecessary power consumption. It has the effect of eliminating
