本考案は内視鏡をＥ・Ｏ・Ｇ（C2H4O）による
消毒時に用いる破裂防止管に関する。[Detailed Description of the Invention] The present invention relates to a rupture-prevention tube used when an endoscope is sterilized with E.O.G (C 2 H 4 O).
近時、使用済の内視鏡の外側および鉗子導入管

いために内視鏡は全体が水密および気密構造とな
つているものが主流となつて来ている。 Recently, we have been cleaning and cleaning the outside of used endoscopes and the inside of built-in tubes such as forceps introduction tubes and forceps operation wire guide tubes.
Disinfection has become more rigorous. Since this cleaning and disinfection is often carried out by automatic machines, it has become mainstream for endoscopes to have a watertight or airtight structure as a whole.
このように水密および気密構造になつている内
視鏡を消毒する方法として種々の方法があるが、

れて充満させて加熱することにより内視鏡の外側
と共に内蔵管内にもＥ・Ｏ・Ｇを入れて滅菌を行
なうものである。 There are various ways to disinfect endoscopes that have a watertight and airtight structure.
One of these methods is disinfection using E・O・G (C 2 H 4 O). This involves placing the endoscope inside the gas chamber, creating a negative pressure inside the gas chamber, and thereby removing air from the internal tube of the endoscope. Next, this gas chamber is filled with E.O.G and heated, thereby sterilizing the endoscope by introducing E.O.G into the internal tube as well as the outside of the endoscope.
しかし、この滅菌過程において、ガス室内を陰
圧にしたときに、内視鏡の可撓管部特に先部にあ

くらんでしまい、ひどい場合には破裂してしまう
ことがある。 However, during this sterilization process, when the gas chamber is brought to negative pressure, the soft outer covering of the endoscope's flexible tube, especially the angle part at the tip, swells due to heat and internal pressure, and in severe cases may rupture.
そこで、特開昭57−164036号に示すような技術

ブ本体を具備する内視鏡用保護チユーブ３であ
る。 Therefore, a technique as shown in Japanese Patent Application Laid-Open No. 164036/1983 was developed. As shown in FIG. 1, this is a protective tube 3 for an endoscope that includes a rigid protective tube body provided outside at least the flexible portion 1 and the curved portion 2 of the body insertion portion of the endoscope. .

を各内視鏡に合わせて形成しておかなければなら
ないために汎用性が無い欠点を有すると共に高価
な製品となる欠点も有している。 Since this is a protective tube made of rigid materials such as metal, heat-resistant plastic, metal blades, synthetic rubber, wood, and bamboo, the entire tube is rigid and difficult to handle, and the gas chamber must be shaped into a long rectangular shape. In addition, the connection part 4 with the endoscope
Since it has to be formed to suit each endoscope, it has the drawback of not being versatile and also having the drawback of being an expensive product.
本考案は、上記の欠点を解決することを目的と

徴とする。 The purpose of this invention is to solve the above-mentioned drawbacks by forming a flexible spiral tube of a desired diameter using a flat plate made of synthetic resin such as Teflon or heat-resistant polyethylene, and inserting an endoscope into the spiral tube. The present invention is characterized in that by inserting at least the angle portion and placing it in the gas chamber, the flexible tube portion is prevented from excessive expansion and rupture when the gas chamber is suddenly made negative pressure.
以下に本考案の一実施例を図面に従つて説明す
る。 An embodiment of the present invention will be described below with reference to the drawings.
第２図は使用状態を示す斜視図であり、５は内
視鏡であつて柄部６およびそれに続く可撓管部７
とライトガイドコード８等から成立つており可撓
管部７の先部にはアングル部９があり柔軟な外被
で被われている。 FIG. 2 is a perspective view showing the state of use, and 5 is an endoscope with a handle 6 and a flexible tube 7 following it.
The flexible tube section 7 has an angle section 9 at its tip and is covered with a flexible jacket.

レキシブルな螺線管であつて破裂防止管を構成

たときに隙間Ｓがあまり大きくならない程度とな
つている。長さは内視鏡の可撓管部７全長が入
り、後端をその螺線が拡がる方向に拡げることに
より柄部６の端部に係止する。 10 is a flexible spiral tube made of a flat plate made of synthetic resin such as Teflon, heat-resistant polyethylene, or synthetic rubber, wound in a spiral shape, and constitutes a rupture-prevention tube. However, there may be a gap. Further, the diameter is such that the gap S does not become too large when the endoscope is inserted. The length is such that the entire length of the flexible tube section 7 of the endoscope is included, and the rear end is latched to the end of the handle section 6 by expanding in the direction in which the spiral expands.
以上の構成を有する破裂防止管によると、破裂
防止管１０内に可撓管部７を挿入して破裂防止管
１０の端部を多少巻戻すようにしてそのばね力に
よつて柄部６の端部に係止して一体とした状態で
Ｅ・Ｏ・Ｇのガス室用にまるめるようにして納め
る。 According to the rupture prevention tube having the above structure, the flexible tube part 7 is inserted into the rupture prevention tube 10 and the end of the rupture prevention tube 10 is slightly rolled back, so that the handle part 6 is It is latched to the end and stored in a unified state so that it can be rolled up for use in the E, O, and G gas chambers.
そこで、一旦ガス室内の空気を抜いて陰圧にす

は外部の急激な圧力低下によつて第３図の点線で
示す如くふくらむが、そのふくらみは破裂防止管
１０の内径内で留まり、その結果アングル部９が
破裂することは無い。この場合、可撓管部７の他
の部分はアングル部９の外被に比較して硬くして
あるために比較的弱い陰圧で行なう場合にはこの
部分での膨張は少ない。 Therefore, the air in the gas chamber is once removed to create a negative pressure, but at this time, the jacket of the flexible tube section 7, especially the angle section 9, swells as shown by the dotted line in Figure 3 due to the sudden drop in external pressure. , the bulge remains within the inner diameter of the burst prevention tube 10, and as a result, the angle portion 9 will not burst. In this case, since the other portions of the flexible tube portion 7 are made harder than the outer cover of the angle portion 9, there is little expansion in this portion when a relatively weak negative pressure is applied.
以上のようにしてガス室内を陰圧にすることに
より内視鏡５内の内蔵管内も少しづつ陰圧とな

常60゜〜70℃の温度内で一定時間保持することに
より滅菌を行なう。 By making the gas chamber negative pressure as described above, the internal tube inside the endoscope 5 also becomes negative pressure little by little, and when the whole becomes negative pressure, when E, O, and G are injected into the two chambers, The gas travels through the gas chamber, the built-in tube, and the rupture-prevention tube through the gap between the spirals, and sterilization is carried out by keeping the gas at a temperature of usually 60° to 70°C for a certain period of time.
なお、上記実施例においては可撓管部全長を破
裂防止管で被つたが、アングル部だけを被うよう
にしてもよい。 In the above embodiment, the entire length of the flexible tube portion is covered with the rupture prevention tube, but only the angle portion may be covered.

る。 According to the present invention having the above structure and function, the rupture prevention tube is constructed by spirally winding a flat plate made of synthetic resin, so that gas can sufficiently enter and exit the rupture prevention tube through the gap. Moreover, because it is flexible, the endoscope can be easily inserted into the rupture-proof tube and the entire endoscope can be bent into any shape, so it can be stored rolled up in a small gas chamber and is fully sterilized. becomes possible.
また構成上、固定用の口金等も必要としないた
めに非常に安価にでき使い捨て用の破裂防止管と
しても使用することができる。 In addition, since the structure does not require a fixed cap or the like, it can be made very inexpensive and can be used as a disposable rupture-prevention tube.
