Abstract

A connector for connecting the end of a chemical tube, a blood tube or a tracheal tube inserted to a human body with that of an external circuit. The connector comprises a male terminal part (2) and a conically-connectable female terminal part (3) composed of an inner cylindrical body (5) and an outer cylindrical body (6) which can rotate relative to each other. On the outer surface of the inner cylindrical body (5) and the inner surface of the outer cylindrical body (6), projected lines (11) and grooves (12) which function as engaging means which can stop the rotation inside the connector by contacting with one another due to elastic deformation of the outer cylindrical body are formed. Accordingly, the conically-connectable rotary connector can be detached easily while a rotation mechanism is provided inside the connector.

Dependent claims

A rotating connector comprising:

a male terminal portion with a cone-shaped outer circumferential surface;
and a female terminal portion with a cone-shaped inner circumferential surface that is connected with the cone-shaped outer circumferential surface in a conically coupled manner, wherein
either one of the female terminal portion or the male terminal portion includes:
an internal barrel;
and an elastically deformable external barrel into which the internal barrel is rotatably inserted relative to the external barrel, and
an engaging device is provided between the outer circumferential surface of the internal barrel and the inner circumferential surface of the external barrel, the engaging device coming in contact with the circumferential surfaces by elastic deformation of the external barrel to enable restraint of the relative rotation.
