The present invention relates to a device which mixes an infusion solution with gas therein and can inject the infusion solution and the gas at the same time through one line. More particularly, the present invention relates to a device for mixing an infusion solution with gas which mixes the infusion solution and the gas such as carbon dioxide which are used various medical operations such as surgeries or liposuction in one device and supplies the infusion solution and the gas through one line. Therefore, the number of devices arranged around a place of operation is reduced, and thus a user can perform operation without distraction. The device for mixing an infusion solution with gas can increase an effect of a medical operation as the infusion solution and the gas can accurately interact with each other on an area for the medical operation. According to the present invention, provided is the device for mixing an infusion solution with gas including: an infusion solution bag needle connected to an infusion solution bag； a needle socket which is joined with the infusion solution bag needle and includes a backflow prevention valve, which is installed on a joining portion and prevents backflow to the infusion solution bag； an infusion solution line socket having one side connected to an infusion solution line； a main body which has both sides joined with the needle socket and the infusion solution line socket and includes a mixing chamber therein； and a gas line socket which is joined with the mixing chamber to communicate with the mixing chamber and includes a backflow prevention valve, which is installed on a joining portion and prevents backflow of the infusion solution to a gas line.본 발명은 인체에 수액과 가스를 하나의 장치에서 혼합하여 하나의 라인으로 동시에 주입할 수 있도록 하는 장치에 관한 것으로, 수술이나 지방 제거술 등의 다양한 시술에 사용되는 수액과 이산화탄소 등의 가스를 하나의 장치에서 혼합하여 하나의 라인으로 공급할 수 있도록 함으로써, 시술하는 장소의 주위에 널려있는 장치들이 간소화되어 방해를 받지 않고 시술할 수 있고, 수액과 가스가 시술하고자 하는 부분에 정확하게 서로 상호작용할 수 있어 시술의 효과가 향상되도록 하는 수액과 가스 혼합장치에 관한 것이다.본 발명
