Description

この発明は内視鏡の給水接続アダプタに関する。   The present invention relates to an endoscope water supply connection adapter.

一般に胃腸検査用の内視鏡には、観察窓の表面を洗浄するための送水管路が内蔵されているが、大腸検査用の内視鏡等にはさらに、観察対象である粘膜面に付いた便などを洗い流すための第２の送水管路が内蔵されている。   In general, endoscopes for gastrointestinal examinations have a built-in water conduit for cleaning the surface of the observation window, but endoscopes for colon examinations are also attached to the mucosal surface to be observed. A second water supply conduit for washing away stools is incorporated.

そのような観察窓洗浄用の第１の送水管路の入口部と観察対象洗浄用の第２の送水管路の入口部とには、第１と第２の送水口金が個別に設けられていて、第１の送水口金には自動給水用の送水タンクの給水チューブを接続し、第２の送水口金には手動給水具の給水チューブを接続するようになっている（例えば、特許文献１）。
特開平１０−２７６９６８ First and second water supply caps are individually provided at the entrance of the first water supply conduit for cleaning the observation window and the entrance of the second water supply conduit for cleaning the observation target. In addition, a water supply tube of a water supply tank for automatic water supply is connected to the first water supply base, and a water supply tube of a manual water supply tool is connected to the second water supply base (for example, a patent) Reference 1).
JP-A-10-276968

しかし、そのような構成の内視鏡では、使用準備の際に、送水タンクの給水チューブと手動給水具の給水チューブを第１と第２の送水口金に個別に接続しなければならないので面倒である。   However, the endoscope having such a configuration is troublesome because the water supply tube of the water supply tank and the water supply tube of the manual water supply device must be individually connected to the first and second water supply caps when preparing for use. It is.

これは、単に二つだから面倒であるということではなく、給水チューブは送水口金に接続されるまではブラブラしていて位置が定まらず、着脱時にはシール機構やクリック機構を係脱させるための気を使う動作が必要なので、二つの給水チューブを個別に接続する作業は、例えば二つ並んだスイッチを操作するような動作に比べて非常に面倒なのである。   This is not just troublesome because there are only two, but the water supply tube does not move until it is connected to the water supply base, and the position is not fixed. Therefore, the operation of connecting the two water supply tubes individually is very troublesome compared to the operation of operating two switches arranged side by side.

そこで本発明は、あい異なる給水装置の給水チューブを内視鏡の第１と第２の送水口金に対して簡単に接続及び分離することができる内視鏡の給水接続アダプタを提供することを目的とする。   Therefore, the present invention provides an endoscope water supply connection adapter that can easily connect and disconnect the water supply tubes of different water supply apparatuses to the first and second water supply caps of the endoscope. Objective.
