The anesthesia machine and ventilator breathing circuit smooth tube  

Including pipe joints are connected with each other and the three joints, the remaining two pipe three through the joint are respectively connected with the screw thread tube, pipe joints, which is characterized in that the first reinforcementaround the periphery of the pipe joints are arranged on the axial direction, andaround the periphery of the pipe joint is provided with an annular second strengthen reinforcement. Connected with the screw thread pipe three pass jointwall between two pipe is provided with third reinforcing ribs, and the increase of the joints and the tube thickness in three pass joint. By adopting the structure, pipe joints and pipe joint is not easy deformation, easy to plug, coordination andimprove the use of stability and sealing, avoiding the air leakage, so the security is good, can guarantee the quality of the products; while in the threaded pipe is provided with third reinforcing ribs, and increase the three joints connecting the corresponding wall and threaded pipe thickness, the respiration loop tube of good intensity, long service life, safety and security.
