the utility model provides a gas conduit for anesthesia machine breathes, includes the tee bend body, the up end symmetry of the tee bend body is equipped with two inside openings of intercommunication and all matches in the opening and be equipped with the screw thread mouth of pipe, equal threaded connection has the spiral cover outside the screw thread mouth of pipe, the up end of spiral cover all is connected with the bellows that is used for conveying gas, the top of bellows is equipped with the cutting ferrule that is used for being connected with the anesthesia machine.

Further, the inner top wall of the screw cap is connected with a first sealing piece for preventing air leakage, and the diameter of the first sealing piece is the same as the inner diameter of the screw cap.

Furthermore, a second sealing piece for preventing air leakage is arranged in the clamping sleeve, and a gap is reserved between the second sealing piece and the clamping sleeve.

Furthermore, a sealing ring for sealing is connected to the outer wall of the bottom end of the threaded pipe orifice.

Furthermore, a group of anti-skid grains with the direction parallel to the rotary cover are arranged on the outer surface of the rotary cover at equal intervals.

(III) advantageous effects

Compared with the prior art, the utility model provides a gas conduit for anesthesia machine breathes possesses following beneficial effect:

1. the utility model discloses, through being connected of screw thread mouth of pipe and spiral cover, the phenomenon that drops is avoided appearing in the in-process that uses, still conveniently changes the part of damage, need not to change whole gas conduit and tee bend body, avoids the waste of resource.

2. The utility model discloses, through first sealing member and second sealing member, can improve the leakproofness of being connected with the tee bend body, can also improve the leakproofness of being connected with the anesthesia machine, and the phenomenon that drops appears in the difficult messenger cutting ferrule, improves the effect of anesthesia.
