PROBLEM TO BE SOLVED: To make the work of attachment easy and speedy as well without leaking air or medicine by lengthwisely forming a pair of recessed lock parts, which are locked and attached to the outer wall of the main body of tube to sandwich both the top ends of a clip for preventing tube drop, adjacently in peripheral direction. SOLUTION: This tube 1 for medical treatment is provided with a main body 2 of tube, which has a prescribed length (about 50 mm) formed from a material such as silicone rubber or vinyl chloride having bioapplicability. The cross section of the main body 2 of tube is made elliptic while having the length of about 25 mm on the side of long diameter and the length of about 10 mm on the side of short diameter. Inside the main body 2 of tube in lengthwise direction, an elliptic lumen 3 is formed while being made eccentric to one long diameter side. On the outer wall of the main body 2 of tube on the side opposed to the side where the lumen 3 is formed, a pair of lock grooves 4 and 4a are formed over the full length in the lengthwise direction adjacently in the peripheral direction. The lock grooves 4 and 4a are formed so as to be locked and attached while sandwiching both the top ends of a clip 5 for preventing tube drop. |
