This creation proposes a kind of catheter fixator, includes: a fixing belt and a catheter fixing piece, which has one first engaging member, which is fixed in the fixing belt. The catheter fixing piece includes one second engaging member, a third engaging member and an elastic band, second engaging member and the third engaging member position what elastic band two sides, uses and combines the catheter fixing piece activity in the fixing belt. The catheter fixing piece fixes a catheter by the elastic band, and by second engaging member and the third engaging member fixes the catheter and activity combines in the fixing belt. By the elastic band of the catheter fixing piece to wind or directly fix, then the fixing belt is movably fixed to by second engaging member and the third engaging member.本創作提出一種導尿管固定裝置，包括有：一固定帶及一導尿管固定件，該固定帶有一第一結合件，該第一結合件固定在該固定帶上。該導尿管固定件包含一第二結合件、一第三結合件及一鬆緊帶，該第二結合件及該第三結合件位於該鬆緊帶兩側，藉以將該導尿管固定件活動結合在該固定帶上。該導尿管固定件藉該鬆緊帶固定一導尿管，藉由該第二結合件及該第三結合件將該導尿管固定且活動結合在該固定帶上。藉由該導尿管固定件的該鬆緊帶以捲繞或直接固定，再藉該第二結合件及該第三結合件活動固定在該固定帶。
