CATHETER WITH OPENING/CLOSING MECHANISM

PROBLEM TO BE SOLVED: To liquidate the complication of the operations carried out by persons engaged in a medical treatment by surely closing and opening a catheter through simple motions by avoiding the rotation of the catheter which gives pains to patients by means of an opening/closing mechanism and, at the same time, to make the operation of the catheter easier and free from wrong operations by making the operated state of the catheter easily visually recognizable. SOLUTION: The connecting section 11 of the catheter C is constituted of a first sliding component A integrally connected to an outer cylinder 31 and a second sliding component B integrally connected to an inner cylinder 32. The sliding components A and B are formed in a state where one of them A and B contains the other in a state where the components A and B can slide in the longitudinal direction of the catheter tube of the catheter so that the circumferences of a blood discharging port 3010 and a blood sending port 3020 may be clogged by the outer cylinder 31. First and second figure constituting elements 51 and 52 are respectively imparted to the outer side face of the first sliding component A and to the portion of the second sliding component B so that the elements 51 and 52 may be joined together and may produce a figure showing a concrete operating state of "opening" or "closing" at the sliding ending point when the first and second sliding components A and B are slid relatively to each other.
