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 present invention has been made to solve the problems of the conventional ultrasonic blood flow promoting device as described above, and it is said that the ultrasonic vibration sufficiently acts on the action part of the human body. It is an object of the present invention to provide an ultrasonic blood flow promoter that can be activated at low cost by easing muscles to promote the increase in body temperature and blood flow and activating by reaching the cell unit of the human body.

An ultrasonic mouth washer according to the present invention made to solve the above problems has a head in which an ultrasonic oscillator is disposed inside a base having an action part, and is formed of a flexible material on the base. An action portion having an ultrasonic radiation surface is disposed on the smooth top surface. In particular, the ultrasonic oscillator preferably has an output of 100 mW / cm ² or less with an amplitude of 1.5 to 1.7 MHz.

  In the present invention, the inner side surface of the action part may be inwardly directed toward a part of the contact surface with the ultrasonic oscillator in the space of the base so as to make good contact with the ultrasonic oscillator. When the protruding portion is provided, the ultrasonic wave from the ultrasonic oscillator is reliably transmitted to the base. In addition, when a conductive fluid such as moisture is present between the action part and the ultrasonic oscillator, the ultrasonic wave from the ultrasonic oscillator more acts on the action part.

  Furthermore, in the present invention, when the ultrasonic radiation surface is curved inward or outward, it comes into contact with a contact portion of a human body, for example, in contact with a tooth or gum. easy.

  When a second action part such as a bristle is disposed inside the base on the back surface of the action part of the head, a brushing effect by brush bristles can be exerted. When the base is formed of a cover body that covers the periphery of the head on which the ultrasonic oscillator is disposed, not only the manufacture but also the replacement is easy.

  Furthermore, when the ultrasonic oscillator for the action part and the ultrasonic oscillator for the second action part are respectively arranged inside the base of the head, ultrasonic waves having sufficient strength are respectively provided. In addition to being able to be applied, the ultrasonic wave oscillating body for the working part and the ultrasonic oscillating body for the second working part can oscillate ultrasonic waves having different frequencies, respectively, and frequencies corresponding to the respective purposes. Can oscillate.

According to the present invention, it is needless to say that the ultrasonic vibration sufficiently acts on the contact portion of the human body, and has sufficient and reliable actions and effects such as an increase in body temperature and promotion of blood flow, and is easy to manufacture. In addition, the manufacturing cost can be reduced.

  Next, embodiments of the present invention will be described in detail with reference to the drawings.

  1 to 4 include a handle body 1 incorporating an ultrasonic generator (not shown) according to the present invention, and a head 3 having an action portion 2 and removably fitted to the tip of the handle body 1. 1 shows a preferred embodiment of an ultrasonic blood flow promoter according to the present invention for an ultrasonic mouth washer of the same type.

  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 addition, if water or electrolyzed water is injected into the space 31, the vibration from the ultrasonic vibrator 12 is reliably transmitted to the action part 2.

  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. When the hardness is 70 degrees or more, the gums are damaged, and when the hardness is 30 degrees or less, the effect of removing plaque is deteriorated.

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. Therefore, the ultrasonic vibration surface is propagated from the ultrasonic radiation surface 21 to the surface of the tooth or gum by bringing the ultrasonic radiation surface 21 which is the surface of the action part 2 into contact with the surface of the tooth or gum. Periodontal disease bacteria are sterilized (not shown).

  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 tooth | gear surface or gum. In addition, since contact is made with a wide contact area, a sufficient amount of ultrasonic waves is reliably transmitted to the tooth surface and gums.

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, cells are activated to promote human blood flow, especially peripheral blood flow, to activate human tissues, increase body temperature, bone growth, fatigue recovery and rehabilitation by massage, removal of plaque It has been proved that the effects of promoting blood flow can be expected, such as the prevention of periodontal disease caused by sterilization of periodontal tissues and the increase of saliva. 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. .

  7 to 9 show different embodiments of the present invention, and the main configuration of the head 3 and the ultrasonic oscillator 12 is substantially the same as that of the above-described embodiment, but the action unit 2 is an ultrasonic wave. It is integrally formed on a base 33 in the form of a cover body formed of a flexible material similar to that of the above-described embodiment, in which the opening 35 at the bottom that is removably crowned on the head 3 on which the oscillator 12 is disposed is used as a detachable means. Is different.

  In this embodiment, since the base 33 on which the action part 2 is arranged can be removed as a cover body, the base 33 (action part 2) can be easily replaced, which is economical. Not only is it hygienic.

Also in the present embodiment, a reverse arc-shaped projecting portion 35 is provided on the inner surface of the base 33 to improve the close contact with the ultrasonic oscillator 12 exposed in the space of the head 3. ing. Further, in the present embodiment, since the protrusions 36 and 36 protrude from the portion of the head 3 where the base 33 is crowned, when the base 33 is crowned, the base 33 extends and the protrusion Since it becomes the state latched by 36,36, there is no worry of coming off during use.

  FIG. 10 shows a different embodiment of the present invention. The action part 2 and other parts have substantially the same configuration as that of the embodiment shown in FIGS. 1 to 4, but as shown in FIG. 2 is different in that a second action part 4 comprising a brush part is implanted on the side of the head 3 sandwiching the ultrasonic oscillator 12.

  As shown in FIG. 10, for example, the second action part 4 including a brush part is implanted on the opposite side across one ultrasonic oscillator 12, and not only the transmission of ultrasonic waves by the action part 2 is performed. Tooth brushing using the second action part 4 is also possible.

  In the present embodiment, the ultrasonic wave is oscillated from the action part 2 and the second action part 4 by one ultrasonic oscillator 12, and in either case, an ultrasonic wave having the same frequency may be oscillated. Although it is good, the switch 13 provided in the handle body 1 switches to a preset frequency according to the use of the action part 2 or the second action part 4 (for example, periodontal treatment, tooth surface cleaning). Can be used to obtain excellent effects.

  Further, FIG. 12 shows a different embodiment of the embodiment shown in FIG. 10, and ultrasonic oscillators 12 and 13 suitable for the action part 2 and the second action part 4 comprising the brush part, respectively. The operation unit 2 and the second operation unit 4 can be used in accordance with the purpose by driving the ultrasonic oscillators 12 and 13 simultaneously or individually.
