Claims

[Scope of Claim for Utility Model Registration] (1) A branch pipe is formed so as to connect with communication holes provided in three directions at appropriate positions on the side wall of a hollow chamber having an appropriate volume, and one of the branch pipes is The branch pipes are positioned facing each other, and a hollow pipe-shaped catheter having an inner diameter slightly larger than the needle is attached to one side of the opposed branch pipes by an appropriate connecting means, and the other branch is A stopper having appropriate flexibility is attached to the conduit by an appropriate connecting means, and the hollow chamber is provided with an operating means at the upper end and is rotatable within the hollow chamber and has a substantially T-shaped communication line. A three-way stopcock is constructed by holding a rotary stopper provided with a hole in a watertight manner, and in a state where the communication hole of the three-way stopcock is aligned with the pair of opposing branch pipes, the above-mentioned A needle having a large diameter portion at the rear end is inserted into the hollow pipe-shaped catheter through a flexible stopper attached to the branch line, with the oblique tip slightly protruding from the tip of the catheter. An intravascular indwelling needle with a three-way stopcock designed to be retained. (2) A request for registration of a utility model characterized in that the needle is provided with an appropriate removable engagement means between a large-diameter portion provided at the rear end and a flexible plug body. The intravascular indwelling needle with a three-way stopcock according to item 1. (3) The intravascular indwelling needle with a three-way stopcock according to claim 1 or 2 of the utility model registration claim, wherein the needle is made of a solid rod.
