The gas inlet to increase the supply pressure of the gas mist so as to be integrated with a gas mist generator, to provide a gas mist pressure bath system for realizing the simplification of the structure and cost reduction. Branches the gas supply means 10, a gas mist generation means 30, and a gas mist pressure bath system and a living-body cover member 50, the gas mist generation means 30, the connection between the gas supply means 10, the gas flow from the connecting part The collision branch portion to be a liquid reservoir, a nozzle for discharging the one of the gas flow which is branched at the branch portion, and a liquid suction pipe for sending the liquid to the nozzle tip, the fluid which is blown up by the gas stream nozzle for discharging a collision member that generates the gas mist and thereby, a merging unit for merging the gas from above the generated gas mist, and a gas introduction portion for guiding to the merging part and the other of the gas flow which is branched at the branch portion, and generated the gas mist and it includes a gas mist discharge portion for collecting and discharging the gas, and the integrally formed.ガスミストの供給圧を上昇させるガス導入部をガスミスト生成器と一体にして、構造の簡易化と低コスト化を実現するガスミスト圧浴システムを提供する。ガス供給手段10と、ガスミスト生成手段30と、生体カバー部材50とを備えるガスミスト圧浴システムであり、ガスミスト生成手段30が、ガス供給手段10との接続部と、接続部からのガス流を分岐させる分岐部と、液体貯留部と、分岐部で分岐された一方のガス流を吐出するノズルと、ノズル先端に液体を送る吸液管と、ノズルが吐出するガス流によって吹き上げられた液体を衝突させてガスミストを生成する衝突部材と、生成されたガスミストに上方からガスを合流させる合流部と、分岐部で分岐された他方のガス流を合流部まで導くガス導入部と、生成された前記ガスミスト及びガスを収集し排出するガスミスト排出部と、を一体的に形成して備える。
