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.

摘要： This invention relates to a continuous drug solution injector equipped with a balloon and used for injecting a drug solution filled in a balloon made of an elastic material into the human body within a predetermined period of time by utilizing the shrinking force of the balloon. A bottomed cylinder (3) is fitted slidably with its bottom facing outward into a tubular body (1) which is formed by connectong a drug solution charge portion (5) having a valve member and a drug solution discharge portion (6) having a drug solution discharge control portion through a flow path change-over valve (4) disposed at an intermediate portion. A plurality of holes (12 or 31) are bored in the tubular body or the cylinder. The peripheral edges of the balloon (2) are fixed air-tight to both the tubular body and the cylinder in such a manner as to encompass the junction between the tubular body and the cylinder as well as the holes. Thus the cylinder can slide relative to the tubular body with the aid of the elasticity of the balloon and the inner pressure of the drug solution when the balloon undergoes expansion and shrinkage, and the balloon can undergo expansion and shrinkage in substantially the same quantity in the direction of the center axis in a longitudinal direction and an axial direction vertical to the former, whereby the drug solution can be injected uniformly without intermission.
