Abstract
A double lumen-type catheter design which prevents damage to a child catheter and loosening of a stud valve of the double lumen-type catheter. A child catheter is housed inside a parent catheter so that it can freely slide, with the back end of the parent catheter joining with a front end of a Y-type connector with a branching path. The back end of the child catheter extends so that it passes through a back of the Y-type connector toward. A stud valve locks the back end of the child catheter at the back end of the Y-type connector. A cover covers the stud valve at the back end of the Y-type connector and the back end of the child catheter, and is attached so that it can be removed and replaced as needed.
