Example (b):

referring to fig. 1-3, the present invention provides a technical solution: a connector device for an arterial puncture tube comprises a plug connector 1 and a sleeve head 2, wherein an inner insertion tube 3 is connected to one side wall of the plug connector 1 facing the sleeve head 2;

the sleeve head 2 and the inner inserting tube 3 of the plug 1 are both made of the existing medical plastic materials, the plug 1 and the inner inserting tube 3 are integrated, and the plug 1 is inserted into the sleeve head 2 through the inner inserting tube 3 to realize the connection and the communication of the plug 1 and the sleeve head 2;

the plug 1 and the sleeve 2 are both in the shape of a circular truncated cone, and the diameter of the end, close to each other, between the plug 1 and the sleeve 2 is larger than the diameter of the end, far away from each other, between the plug 1 and the sleeve 2;

during connection, generally, manual connection operation is performed, a worker respectively holds the plug connector 1 and the sleeve head 2 with two hands, and inserts the inner insertion tube 3 into the sleeve head 2, and the outer walls of the plug connector 1 and the sleeve head 2 are inclined, so that the effect between the plug connector 1 and the sleeve head 2 and the hands is increased, and the connection is convenient;

as shown in fig. 4, which is a schematic structural diagram of the conventional joint, when connecting, a worker holds two connecting pieces with two hands, draws the two connecting pieces together, inserts the two connecting pieces, and connects the two connecting pieces, and the raised lines increase friction, so that the two connecting pieces can be rotated relatively when connecting;

the design of round platform shape can improve and connect the portability through this design, and has avoided the drawback that current articulate back used.

The diameter of the end which is close to the plug 1 and the sleeve 2 is the same, the plug 1 is connected with the plug 4 towards one side wall of the sleeve 2, and the sleeve 2 is provided with a slot 5 which is matched with the plug 4 towards one side wall of the plug 1.
