Abstract: A method is provided to measure the difference of lip closure force between left and right lips and find weaknesses in left and right lips that are caused by hypoplasia, atrophy and paralysis so that such symptoms can be treated in early stages. A lip force detecting apparatus for detecting the closure force of lips includes a housing, the upper base portion and the lower base portion for lips protruding from the housing and can be pressed using upper and lower lips, the control unit respectively measures the pressing force generated when the left side of lips presses the upper base portion and the lower base portion, and measures the pressing force generated when the right side of lips presses the upper base portion and the lower base portion.

Abstract: This invention provides a nasal device for use while breathing and adapted for insertion within a human nasal cavity, the device comprising: a main body being tubular in shape having a hollow structure which extends from the end of front side to the end of rear side; a front opening portion and a rear opening portion; wherein the hollow structure is in a shape that the rear side becomes narrower towards the front side having a smaller diameter. The nasal device in this invention is easy to carry, which can be placed inside nasal cavity to bring sufficient air into the respiratory tract.

Abstract: A periodontal pocket probing device facilitating fabrication and application and effectively reducing the cost is disclosed to include a main body, and a probe having a connection portion located at one end thereof and connected to the main body and a flat probing tip located at an opposite end thereof and defining a flat front end edge on a front side thereof opposite to the connection portion for allowing the produced pressure to be distributed in all directions to reduce the patient's pain upon insertion of the probe into the deep inside of a periodontal pocket.

Abstract: An oral cavity insertion tool (1) has a flat base part (10), which includes a pressing piece (30) that is tabular and folded back forward at the upper end, a pressing piece (40) that is tabular and folded back forward at the lower end and, and an air hole (13) that penetrates in forward and backward directions, a backward projection part, which includes an opposing wall part (21) that projects backward from the center of the base part (10), provides a gap in which upper teeth can be inserted between the opposing wall part (21) and the base part (10), and faces the base part (10), and an opposing wall part (81) that provides a gap in which lower teeth can be inserted between the opposing wall part (81) and the base part (10), and faces the base part (10), and a lingual frenotomy pressing plate (50), which is tabular and provided to extend downward and backward from the rear end of the backward projection part, and the lingual frenotomy pressing plate (50) has a pressing part (51) that curves to curl up, toward

Abstract: Oral lip and chin muscle rehabilitating device made of flexible material and having an annular open shape in accordance with the configuration of human oral lips. One side of the upper edge of the opening is formed with a recessed upper lip rest section extending outward and upward. One side of the lower edge of the opening is formed with a recessed lower lip rest section extending outward and downward. The upper and lower lip rest sections respectively receive therein the upper and lower lips of a user. A resilient connecting section is connected between the upper and lower lip rest sections to provide a certain resilient stretching force therefor. The oral lip and chin muscle rehabilitating device is positioned between the upper and lower lips of the user to rehabilitate and train the lip and chin muscle and recover the closing function of the lips.
