PROBLEM TO BE SOLVED: To provide an anesthetic tank and an anesthetic false injection prevention system in which leakage of volatile anesthetic due to looseness of an injection adapter is prevented without the use of leakage preventive measures against seal components, and change components in multiple types of anesthetic tank are simplified.SOLUTION: An anesthetic tank 7 includes an insertion port 71 with an injection adapter of an anesthetic container inserted therein, and a receiving part 72 in communication with the insertion port 71. The volatile anesthetic in the anesthetic container is injected into the receiving part 72. An identification member 33 capable of being freely turned in the central axis circumference of the insertion port 71 is arranged in the outside of the insertion port 71. A key groove for identifying the type of the volatile anesthetic in connection with a key provided at the injection adapter is provided in an inner face of an insertion hole 33h where the injection adapter of the identification member 33 can be inserted. The identification member 33 has an outer circumferential part being held by a lid member 8 provided with an opening 82 facing the insertion port 71 and the insertion hole 33h.SELECTED DRAWING: Figure 12【課題】シール部品などの漏れ防止策を用いずに注入アダプタの緩みによる揮発性麻酔薬の漏れを防ぎ、かつ複数種類の麻酔薬タンクにおける変更部品を簡略化した麻酔薬タンクおよび麻酔薬誤注入防止システムを提供する。【解決手段】麻酔薬タンク７は、麻酔薬容器の注入アダプタが挿入される挿入口７１と、挿入口７１に連通した貯留部７２とを備え、麻酔薬容器内の揮発性麻酔薬は貯留部７２に注入される。挿入口７１の外側には、挿入口７１の中心軸周りで回動自在な識別部材３３が配設されていて、識別部材３３の注入アダプタが挿入可能な挿入孔３３ｈの内面には、注入アダプタに設けられたキーと連携して揮発性麻酔薬の種類を識別するキー溝が設けられている。識別部材３３は、挿入口７１および挿入孔３３ｈに対面する開口８２が設けられた蓋部材８によって外周部が押さえられる。【選択図】図１２
