摘要： An intermittent urethra-indwelling catheter set (10) comprises a catheter unit (1), a sterilization case (2), and a cap (3). The catheter unit (1) has a catheter main body (11), a balloon (12) expansibly and contractably installed on the tip portion of the catheter main body (11), and a reinforcement tube (18) inserted in an upper inner cavity of a urine guide path (111) of the catheter main body (11). The cap (3) is removably fitted on the upper portion of the catheter main body (11), and opens and closes a discharge opening. Problems that insertion into a urethra is difficult because of flexibility of a catheter main body, and attachment and removal of the cap (3) require force on fingertips and skillfulness are solved, and a user with weak and declined strength can more simply and easily use the set.
