The spring 3 inside the two arms 1a and 1b is detachable, and the two arms 1a and 1b and the spring 3 are made of synthetic resin. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

本発明は、鼻鏡に関するものである。 The present invention relates to a nasal mirror.

鼻鏡（鼻鏡器）は、鼻孔を拡げて、鼻の検診、治療などを行うときに使用されるやっとこ様の器具で、従来の鼻鏡は、金属製で、高価で、集団検診などでは、その都度、消毒液に浸漬してから診察しているが、複数の者に繰り返して使用するので、極めて不衛生であった。
鼻鏡には、和辻式や俣野式やハルトマン式やフレンケル式などがあるが、基本的には、その先端側で鼻孔内に挿入して鼻孔を拡げる開拡部と手元側で手で把持する把持部とを有してなり、当該把持部は、バネにより付勢されている。
当該把持部は、当該バネが使用により、劣化してきて、そのバネ力が衰えると、鼻の検診、治療などを行うときの作業性を悪化せしめる。従来の鼻鏡は、当該バネが、鼻鏡と一体化されて固定されているので、交換が不可能で、当該バネの劣化により、当該バネだけの新しいものの交換は出来ず、当該鼻鏡全体を処分せざるを得なかった。
又、当該鼻鏡の滅菌・消毒に際しては、繰り返し滅菌や煮沸消毒などが行われるが、従来の鼻鏡は、当該バネが、鼻鏡と一体化され固定化されているので、当該煮沸消毒や繰り返し滅菌に際して、当該バネの取り外し、分解・組立が容易に出来ず、滅菌・消毒が不充分となることがあった。 A nasal scope (nasophoscope) is a last-like instrument used to expand the nostrils and perform nasal examinations and treatments. Conventional nasal scopes are made of metal and are expensive. In each case, the patient was examined after being immersed in a disinfectant solution, but it was very unsanitary because it was used repeatedly by several people.
There are various types of nasal mirrors, such as Japanese style, Sugano style, Hartmann style, and Frenkel style. Basically, it is inserted into the nostril on the tip side and the nostril is widened and gripped by the hand. And the gripping portion is biased by a spring.
When the spring is deteriorated by use and the spring force is weakened, the gripping portion deteriorates workability when performing nasal examination, treatment, and the like. In the conventional nasal mirror, since the spring is integrated and fixed with the nasal mirror, it is impossible to replace it, and due to deterioration of the spring, a new one cannot be replaced. I had to dispose of.
In sterilization and sterilization of the nasal mirror, repeated sterilization and boiling sterilization are performed. However, in the conventional nasal mirror, the spring is integrated with and fixed to the nasal mirror. During repeated sterilization, the spring could not be easily removed, disassembled and assembled, resulting in insufficient sterilization and disinfection.

本発明は、上記のような従来技術の欠点を解消できる技術を提供することを目的としたものである。

当該鼻鏡Ｎは、合成樹脂製で、当該鼻鏡Ｎを構成する２つのア−ム１ａ、１ｂ、ピン２、ワッシャ−２０１及びバネ３の全てが合成樹脂製である。
本発明の当該鼻鏡Ｎは、合成樹脂製で、使い捨てとすることができる。
当該合成樹脂としては、ポリプロピレンが好ましい。当該ポリプロピレン製鼻鏡Ｎは、耐熱温度が１６０℃以上あり、当該鼻鏡の滅菌・消毒に際して、繰り返し滅菌や煮沸消毒を充分行うことが出来る。 The nasal mirror N is made of synthetic resin, and all of the two arms 1a and 1b, the pin 2, the washer 201 and the spring 3 constituting the nasal mirror N are made of synthetic resin.
The nasal mirror N of the present invention is made of synthetic resin and can be disposable.
As the synthetic resin, polypropylene is preferable. The polypropylene nasal mirror N has a heat resistant temperature of 160 ° C. or higher, and can be sufficiently sterilized and boiled and disinfected when the nasal mirror is sterilized and disinfected.

図４により当該鼻鏡Ｎの作用を説明するに、２つのア−ム１ａ、１ｂのそれぞれの把持部１００ａ、１００ｂを手で握り、手に力を込め当該把持部１００ａ、１００ｂを内側に押圧すると、当該２つのア−ム１ａ、１ｂのピン２による固定位置を支点（Ｘ）として、当該２つのア−ム１ａ、１ｂの鼻孔の開拡部１０１ａ、１０１ｂが開拡する。
力を緩めれば、当該２つのア−ム１ａ、１ｂのそれぞれの把持部１００ａ、１００ｂが、当該２つのア−ム１ａ、１ｂの固定位置を支点（Ｘ）として、外側に、元の位置に戻り、それに伴い、鼻孔の開拡部１０１ａ、１０１ｂが、内側の元の位置に戻り、閉じる。
当該開拡部１０１ａ、１０１ｂの先端部側には、外側に凸で内側に凹みを有する鼻孔挿入部１０１０ａ及び１０１０ｂを備え、当該鼻孔の開拡部１０１ａ、１０１ｂの開拡により広がり、一方、当該鼻孔の開拡部１０１ａ、１０１ｂの閉じにより、呼吸のための透通孔Ｈが形成される。 The operation of the nasal mirror N will be described with reference to FIG. 4. The gripping portions 100a and 100b of the two arms 1a and 1b are gripped by the hands, and the gripping portions 100a and 100b are pressed inward by applying force to the hands. Then, the nostril widening portions 101a and 101b of the two arms 1a and 1b are expanded using the fixed position of the two arms 1a and 1b by the pin 2 as a fulcrum (X).
If the force is loosened, the gripping portions 100a, 100b of the two arms 1a, 1b are moved outwardly to the original position with the fixed position of the two arms 1a, 1b as a fulcrum (X). Accordingly, the nostril spreading portions 101a and 101b return to the original inner positions and close.
On the distal end side of the spread portions 101a and 101b, there are nostril insertion portions 1010a and 1010b that are convex outward and have indentations on the inside, and spread by the spread of the nostril spread portions 101a and 101b. By the opening of the nostrils 101a and 101b, a through hole H for breathing is formed.

当該鼻鏡Ｎの上記のような機能に関して、バネ３は重要であり、バネ作用が衰えてくると、当該鼻鏡Ｎは使い物にならない。当該バネ３の劣化に対して、本発明では、当該バネ３は、把持部１００ａ、１００ｂの内部で、脱着可能に構成されてなり、しかも、バネ３側のバネ先端部３０１ａ、３０１ｂの各穴部３０１ａ，３０１ｂに、２つのア−ム１ａ、１ｂ側の各突起部１０００ａ、１０００ｂを嵌合させれば、簡単に、バネ３を把持部１００ａ、１００ｂの内部に装着することができ、一方、当該バネ３側のバネ先端部３０１ａ、３０１ｂの各穴部３０１ａ，３０１ｂと、２つのア−ム１ａ、１ｂ側の各突起部１０００ａ、１０００ｂとの嵌合を解けば、当該バネ３を、当該２つのア−ム１ａ、１ｂから容易に脱すことができるので、その脱着も容易で、従来の鼻鏡では、当該バネが、鼻鏡と一体化され固定化されているので、当該煮沸消毒や繰り返し滅菌に際して、当該バネの取り外し、分解・組立が容易に出来ず、滅菌・消毒が不充分となることがあったが、本発明では、脱着が容易なので、当該煮沸消毒や繰り返し滅菌に際して、当該バネの取り外し、分解・組立を容易に出来、滅菌・消毒を充分行うことができ、又、当該バネ３をポリプロピレン等の合成樹脂製とすれば、耐熱温度が１６０℃以上あり、当該鼻鏡の滅菌・消毒に際して、繰り返し滅菌や煮沸消毒を充分行うことが出来る。 Regarding the above function of the nasal mirror N, the spring 3 is important, and when the spring action is weakened, the nasal mirror N is not useful. In the present invention, the spring 3 is configured to be detachable inside the gripping portions 100a and 100b against the deterioration of the spring 3, and each of the holes in the spring tip portions 301a and 301b on the spring 3 side. If the projections 1000a and 1000b on the two arm 1a and 1b sides are fitted to the parts 301a and 301b, the spring 3 can be easily mounted inside the gripping parts 100a and 100b. When the fitting between the holes 301a and 301b of the spring tip portions 301a and 301b on the spring 3 side and the projections 1000a and 1000b on the two arm 1a and 1b sides is released, the spring 3 is Since it can be easily detached from the two arms 1a and 1b, the attachment and removal thereof is easy. In the conventional nasal mirror, the spring is integrated and fixed with the nasal mirror. Or during repeated sterilization In some cases, the spring cannot be easily removed, disassembled and assembled, and sterilization and disinfection may be insufficient. It can be easily removed, disassembled and assembled, and can be sterilized and disinfected sufficiently. If the spring 3 is made of a synthetic resin such as polypropylene, the heat-resistant temperature is 160 ° C. or higher. In disinfection, repeated sterilization and boiling disinfection can be sufficiently performed.
