Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a blood circulation improving device used for the prevention and treatment of periodontal disease due to ischemic injury in the oral cavity, and more particularly to a direct vibration of a massage such as rubbing a diseased part. Is a system that allows blood circulation improvement treatment to be performed even for unbearable symptoms.

[0002]

2. Description of the Related Art Recently, it has been recommended to take measures against periodontal disease by consciously removing plaque during daily tooth brushing. Products such as electric toothbrushes and toothbrushes in which the shape of the tips of the brushes are changed are emphasized for their effectiveness in removing plaque.

Periodontal disease is associated with periodontal tissues such as periodontal ligament, alveolar bone, and gingiva (gingiva), and in mild cases such as gingivitis, it can be treated by removing plaque. However, when the symptom progresses, a gap may occur between the tooth and the gingiva, and the swelling of the gingiva may become severe and pus may appear. Furthermore, the tooth becomes loose or the tooth comes off, and so-called alveolar pyorrhea becomes prominent. At this stage, a complete cure cannot be expected with daily plaque removal by tooth brushing.

It is said that when periodontal disease is left and alveolar pyorrhea is caused, causative bacteria enter the blood vessels and spread throughout the body, leading to the onset and progression of systemic diseases such as heart disease or diabetes. It is being appreciated.

[0005]

As described above, periodontal disease can be expected to be cured completely by removing dental plaque in the case of mild illness such as gingivitis. However, it is difficult to cure completely by removing plaque alone, and effective measures are required in such cases.

[0006] Periodontal disease is caused by bacteria in dental plaque, but it is also said that ischemic disorders such as congestion of periodontal tissues are also a factor. Therefore, massaging the gums with fingers may be taught in actual dental practice.

However, when inflammation is advanced, it is said that even if the inflamed area is lightly rubbed, the massage will be painful, and brushing with a toothbrush is painful and basically difficult.

Further, even when the symptoms are not as advanced as above, the tissue itself is weakened at the inflamed site, so that it is easily damaged. Therefore, when an electric toothbrush or the like is used to apply strong vibration or shock, it may damage the gingiva or the like, which may worsen the symptoms.

Regarding periodontal disease, as mentioned above, it is necessary to carefully remove plaque during tooth brushing, but efforts are usually made to maintain or improve the blood circulation condition of the gingiva and the like in order to prevent congestion. Is also required.

Therefore, the present inventor has considered that it is necessary to develop a technique capable of improving blood circulation at an inflamed site without giving a strong shock or vibration, regardless of the degree of symptoms, and without causing pain.

An object of the present invention is to make it possible to improve blood circulation in an inflamed area in the oral cavity such as periodontal disease by ultrasonic waves.

[0012]

The present invention is an apparatus for improving blood circulation of oral tissues by ultrasonic waves, wherein the ultrasonic wave is applied to the ultrasonic oscillator and the irradiation target site in the oral cavity. And an ultrasonic wave irradiating section for irradiating the ultrasonic wave generated by the sonic oscillator. It is characterized in that the ultrasonic wave irradiation unit is applied to the gingival part as the irradiation target site directly or via a drug.

Since ultrasonic waves are highly attenuated in the air, the structure of the present invention adopts a structure in which the ultrasonic wave irradiation section is applied to the irradiation target site. For example, the gingival part may be directly contacted, or a drug effective for periodontal disease may be applied to an irradiation target part, and an ultrasonic wave irradiation part may be applied to the applied drug for use.

[0014] irradiation ultrasound, 200kH _Z or higher, 800
kH, characterized in that _Z is an ultrasonic following frequency ranges. Irradiated ultrasonic waves are ultrasonic waves in a frequency range in which a blood flow change amount is 50 ml or more within a time period before returning to blood flow before irradiation after ultrasonic wave irradiation within 1 minute of irradiation time. .

The effectiveness was experimentally confirmed by grasping how much the blood flow after irradiation increased as compared with that before irradiation, as the gingival blood circulation change amount. 1 increase in blood flow
00KH _Z above has been confirmed within the 900KH _Z,
If the increase in blood flow is too small, the effectiveness of improving blood circulation is poor. From the viewpoint of more effective ensuring, 200KH _Z above, preferably the following frequency 800kH _Z.

Further, from the viewpoint of being able to use it on a daily basis without any hassle, and aiming at more effective blood circulation improvement, the irradiation time can be controlled within 30 seconds to 1 minute without any special time being applied to irradiation ultrasonic waves. It is preferable to irradiate with a frequency capable of ensuring a blood change amount of 50 ml or more, more preferably 60 ml or more, which contributes to improvement of blood circulation.

If the irradiation time is kept within 30 seconds to less than 1 minute, it is possible to use a clearance time that does not become a burden, for example, by adjusting it to the time for brushing teeth. If the blood circulation improving treatment can be easily performed, it is possible to continue the operation for a long time without getting tired, and it is possible to further secure the effectiveness.
