JP5666854B2 - Ultrasonic blood flow promoter - Google Patents

Description

  The present invention relates to an ultrasonic blood flow promoter using ultrasonic waves, and is used in many fields such as medical treatment, beauty care, and hygiene.

  Many devices using ultrasonic waves have been proposed in the past, activating human tissues by promoting blood flow in the human body, especially peripheral blood vessels, such as increased body temperature, bone growth, fatigue due to massage. It is used for recovery and rehabilitation, plaque removal, periodontal sterilization, prevention of periodontal disease due to increased saliva, and washing of pores by foaming action due to cavitation.

By the way, many of the conventional ultrasonic devices have a large ultrasonic vibration amplitude of, for example, about 10 to 10 ³ MHz, such as a beauty device presented in Japanese translations of PCT publication No. 2004-538039. It has a large output that can expand pores, and has a large output that can pass through the human body such as skin and fat, like an ultrasonic diagnostic machine, and cannot be used easily.

  In addition, an ultrasonic toothbrush is known as a simple device using a battery and ultrasonic vibration energy, and is disclosed in, for example, Japanese Patent Publication No. 7-509151. This ultrasonic toothbrush is an ultrasonic oscillator. The ultrasonic vibration radiated from the hair is transmitted to the user's teeth through saliva adhering to the brush bristles and around the bristles, toothpaste, etc., resulting in toothbrushing action such as disassembly and cleaning of plaque bacteria and massage of gums In particular, recently, it has been known that ultrasonic vibration of a specific frequency is effective in sterilizing oral bacteria such as periodontal disease bacteria, and is also used for mouth washing.

  However, in the conventional ultrasonic toothbrush, ultrasonic vibration is transmitted efficiently in water, but the ultrasonic transmission efficiency of brush hair made of thin and soft hair is considerably lower than in water. Saliva, toothpaste and the like adhering to the brush hair being brushed are also effective for ultrasonic transmission, but these contain foam, powder, etc., so the ultrasonic transmission efficiency is lower than underwater. In addition, there is a case where the ultrasonic vibration emitted from the vicinity of the side surface of the surrounding substrate where the bristle is implanted is stronger than the brush bristle part. It is limited to a strength that does not exceed safety standards so as not to adversely affect living tissue. That is, the ultrasonic vibration radiated from the ultrasonic oscillator toward the bristles is considerably attenuated at the tip of the bristles in the brushed oral cavity, so that the brushing effect by the ultrasonic vibrations can be suppressed. Increasing the ultrasonic output to compensate for this attenuation has a biological safety problem, and improving the transmission efficiency of the ultrasonic vibration of the brush bristle portion is an extremely important issue in order to improve the performance of mouth cleaning. It was.

  Therefore, as a measure for facilitating the transmission of ultrasonic waves, as shown in Japanese Patent Application Laid-Open Nos. 2004-148079 and 2005-66024, a position facing the ultrasonic vibration surface of the ultrasonic oscillator. Protrusions made of a flexible material such as rubber are arranged on the base arranged in the above, and a brush head in which brush hairs are implanted around the projection group is provided, and the projection group formed by the flexible material is interposed. Thus, the ultrasonic vibration is efficiently transmitted to the tooth portion to improve the brushing performance. However, in the case where a group of protrusions made of a soft material such as rubber is arranged on the base, each protrusion cannot sufficiently transmit ultrasonic waves by irregularly reflecting ultrasonic waves, and is further arranged around the protrusion groups. The bristles do not interfere with contact with the teeth and gums and cannot sufficiently transmit ultrasonic waves, and it is necessary to implant the bristles around the protrusions, which complicates the manufacturing process and increases the product cost. There was a problem of becoming.

  On the other hand, for example, as disclosed in Japanese Patent Application Laid-Open No. 2006-239368, an oral hygiene instrument shaped like a mouthpiece has been proposed, but the apparatus becomes complicated and needs to be adjusted according to the user. It is hard to say that it is a simple means.

  The handle body 1 incorporates a known ultrasonic generator such as a battery power source and an ultrasonic generator circuit, and receives an ultrasonic signal output from the ultrasonic generator into an insertion portion 11 formed at the tip. An ultrasonic vibrating body 12 that vibrates is disposed.

On the other hand, the head 3 to be inserted into the handle body 1 in a replaceable manner is formed with a space 31 into which the insertion portion 11 is inserted on the bottom surface in the present embodiment, and is disposed at the opposite portion of the ultrasonic vibrator 12 portion. The working portion 2 is formed integrally with the base 33 .

  In particular, in the present embodiment, the base 33 and the action portion 2 are formed of a rubber material having elasticity such as silicone rubber or elastomer. In addition, the ultrasonic wave emitting surface 21 as a surface is smooth, and the action part 2 is an integral multiple of the ultrasonic wavelength λ emitted by the ultrasonic vibrator 12 at the narrowest width H and has a height L. Is formed to be an integral multiple of the ultrasonic wavelength λ, and the ultrasonic wave emission in the width direction and the front-rear direction is improved.

Furthermore, it is preferable that the flexible material for molding the action part 2 has a hardness of about 30 to 70 degrees .

In the present embodiment, the ultrasonic vibrator 12 is, for example, 1.V by ultrasonic signals output from an ultrasonic generator (not shown) built in by turning on the switch 13 provided in the handle body 1. When it is vibrated at an output of 100 mW / cm ² or less with an amplitude of 5 to 1.7 MHz, the vibration propagates to the action part 2. Thus, the ultrasonic vibrations to the surface of the skin from the ultrasonic wave emitting surface 21 by abutting the ultrasound emitting surface 21 which is the surface of the working portion 2 of the human body surface of the skin Ru propagated.

At this time, in this Embodiment, since the action part 2 does not have the conventional brush part, and the ultrasonic radiation surface 21 which is a surface is smooth, the action part 2 is directly on the human skin , and Since contact is made with a wide contact area, a sufficient amount of ultrasonic waves is reliably transmitted to the skin .

FIGS. 5 and 6 are thermographic images for confirming the blood flow promoting effect of the present embodiment by bringing the ultrasonic vibrator 12 of the present embodiment into contact with the human arm as shown in FIG. 5A. It is a photograph showing a measurement experiment, and was vibrated with an output of 100 mW / cm ² or less with an amplitude of 1.5 to 1.7 MHz.

  As shown in FIGS. 5B and 5C, the measurement was performed using a thermography (NEC Sanei TH7102MX) (set value (change value set to 0.5 ° C., intermediate temperature set to 35 ° C.)).

  As a result, at the start of FIG. 6 (a), the temperature of the arm portion to which the ultrasonic vibrator was applied was about 36 ° C. in a resting state, but when 18 seconds passed from the start of FIG. The temperature of the vibrating body part rises to about 36.5 to 37 ° C., the blood vessel part of the arm and the back part of the hand rise to about 36.5 ° C., and the back of the hand when 28 seconds elapse from the start of FIG. It was confirmed that this portion rose to about 37 ° C. and increased to about 38 ° C. in FIG. 6 (d) when 34 seconds had elapsed from the start.

From this, by using the ultrasonic blood flow promoter according to the present embodiment, blood flow is generated through the blood vessel part in the direction of gravity, and in that part, body temperature rises particularly in peripheral blood vessels (capillaries). Yes, the cells are activated and the blood flow of the human body, especially the blood flow of the peripheral blood vessels, is activated to activate the tissues of the human body, the body temperature rises, bone growth, fatigue recovery and rehabilitation by massage, etc. It was proved that the effect of promotion can be expected. In addition, although the same measurement experiment was performed using the ultrasonic equipment using the vibration of the amplitude (16000 stroke, 8000 rpm) by the electric motor that can feel the vibration in the conventional human body, the increase in body temperature and the promotion of blood flow were not seen. .
