This creation is a kind of pipe joint structure,It connects end and a catheter body is socketed,And the blocking groove of pipe protrusion set by catheter body,Oblique surface set by blocking flange part along pipe joint ontology,Blocking what blocking flange part is imported,And the end blocking of catheter body supports what step shape support division,And make anti-leak state of the pipe joint ontology combined with catheter body in closely sealed pivot joint,What fitting blocking Hou will not fall off leakage,And pipe joint ontology and catheter body are in the state that can be rotated,And link end and link with medical host,The effect of to reach combination stability and good ease of use.本創作係一種導管接頭結構，其導接端部與一導管體套接，而導管體所設管凸部之卡制凹槽，順導管接頭本體之卡制凸緣部所設斜導面，導入卡制於卡制凸緣部，且導管體之端部卡制抵持於階級狀抵持部，而使結合之導管接頭本體與導管體呈密合樞接之防洩漏狀態，於套合卡制後即不會產生脫落洩漏，且導管接頭本體與導管體呈可轉動狀態，而連結端部即與醫療主機連結，以達結合穩定性及使用便利性佳之功效。
