このように、指挿入部54を軟質の合成樹脂にて形成することによって、挿入される指がフィットするので、口腔ケア時や治療時に、開口補助具50が指から抜けるのを防ぐことができる。   Thus, since the finger to be inserted fits by forming the finger insertion portion 54 with a soft synthetic resin, it is possible to prevent the opening assisting tool 50 from coming off the finger during oral care or treatment. .

また、歯接触部53を軟質の合成樹脂にて形成することによって、口腔ケアを受ける者が歯と歯茎を痛めるのを防止することができ、且つ、指挿入部54と歯接触部53とは重なっていないので、口腔ケアを受ける者が治療時に歯接触部53を強く噛んだとしても、施術者の指を痛めることがない。尚、ここで言う軟質の合成樹脂とは、引張力や押圧力を加えることによって容易に変形可能な伸縮性及び弾性を備えた合成樹脂のことである。   Further, by forming the tooth contact portion 53 with a soft synthetic resin, it is possible to prevent a person receiving oral care from damaging the teeth and gums, and the finger insertion portion 54 and the tooth contact portion 53 are Since they do not overlap, even if a person who receives oral care bites the tooth contact portion 53 at the time of treatment, the finger of the practitioner will not be hurt. The soft synthetic resin referred to here is a synthetic resin having elasticity and elasticity that can be easily deformed by applying a tensile force or a pressing force.

また、図7に示す開口補助具50は、少なくとも歯接触部53と指挿入部54の一方又は両方を軟質の合成樹脂にて形成した例であり、その他の部分も含めて開口補助具全体を軟質の合成樹脂で形成してもよい。さらに、歯接触部53と指挿入部54以外の部分を硬質の合成樹脂又はその他の材質で形成してもよい。   7 is an example in which at least one or both of the tooth contact portion 53 and the finger insertion portion 54 is formed of a soft synthetic resin, and the entire opening aid including the other portions. You may form with a soft synthetic resin. Furthermore, you may form parts other than the tooth contact part 53 and the finger insertion part 54 with a hard synthetic resin or another material.

尚、本発明の趣旨を逸脱しない範囲において、様々な実施形態をとることができることは言うまでもない。例えば、軟質の合成樹脂で形成された筒状の保護部材を別体として用意し、この保護部材が歯接触部3,53を覆うように、着脱自在に設置する構成としてもよい。このように構成することによって、歯の接触により保護部材が傷んだ場合には、保護部材のみを交換すればよく、さらに経済的な開口補助具となる。   In addition, it cannot be overemphasized that various embodiment can be taken in the range which does not deviate from the meaning of this invention. For example, a cylindrical protective member formed of a soft synthetic resin may be prepared as a separate body, and the protective member may be detachably installed so as to cover the tooth contact portions 3 and 53. By comprising in this way, when a protection member is damaged by contact of a tooth, it is only necessary to replace the protection member, and it becomes a more economical opening aid.

本発明の開口補助具は、歯科医師、歯科衛生士、看護師、介護者等が、障害者、高齢者等の口腔ケア又は歯の治療を行う時に、口を大きく開けた状態を保持する道具として使用される。   The opening aid of the present invention is a tool that keeps the mouth wide open when a dentist, dental hygienist, nurse, caregiver or the like performs oral care or treatment of a disabled person, an elderly person, etc. Used as.
