Claims

[Scope of utility model registration request]

a cylindrical body with a pipe-shaped indwelling catheter coaxially connected to its tip; a bottomed cylindrical body with a bottom fixed to the rear end of the body and a screw formed on the outer periphery of the opening; a cylindrical cap with a bottom formed with a screw and screwed into the opening of the cylindrical body;
A cylindrical rubber-like elastic body filled inside the cylindrical body, and a cylindrical rubber elastic body coaxially attached to the cap so as to slide on the inner surface of the cylindrical body and press the elastic body when the cap is screwed onto the cylindrical body. from the indwelling catheter through a through hole that is formed of a columnar protrusion integrally provided on the inner bottom surface of the cap and that penetrates into the main body through the axes of the cap, protrusion, elastic body, and cylindrical body. A metal pipe needle is inserted from the cap side so that its tip is exposed, and by tightening the threaded portion, the inner wall of the through hole of the elastic body is brought into close contact with the outer periphery of the metal pipe needle, and the pipe needle is inserted into each of the metal pipe needles. An arteriovenous indwelling catheter characterized in that the through hole of the elastic body is opened and closed by changing the degree of tightening of the threaded portion after being removed from the through hole.
