PROBLEM TO BE SOLVED: To provide a gas supply unit capable of detecting that a connection part of a gas pipe for supplying gas such as medical gas is released.SOLUTION: A sound emitting part 3 for emitting sound by a flow of gas when the connection of a connection part 2 is released is provided to the connection part 2 of a connection tube 1 for connecting a first tube 11 as an upstream side gas pipe, and a second tube 12 as a downstream side gas pipe. At a normal time, the first tube 11 and the second tube 12 are connected in the connection part 2 so that no sound is emitted from the sound emitting part 3, and when the connection of the connection part 2 is released, the sound emitting part 3 emits sound by the flow of gas, thereby detecting that the connection part 2 is released.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2016,JPO&INPIT【課題】医療用ガス等のガスを供給するガス配管の連結部が解けたことを検知することが可能なガス供給器の提供。【解決手段】上流側ガス配管としての第1チューブ11と下流側ガス配管としての第2チューブ12とを連結する連結管1の連結部2に、連結部2の連結が解けた際にガスの流れによって音を発する発音部3を備え、正常時には、発音部3から音を発しないように連結部2は第1チューブ11と第2チューブ12とが連結され、連結部2の連結が解けた際には、発音部3がガスの流れによって音を発するので、連結部2が解けたことを検知することが可能となる。【選択図】図3
