A tubular fitting for medical fluid lines includes a hollow body within which a male connector and an opposite female connector are coaxially housed. The male connector is coupled in rotation with respect to the body in a direction corresponding to a screwing with a female connector of the line, while it is normally freely rotatable in the unscrewing direction, in the same way as the female connector is coupled in rotation with respect to the body in the direction corresponding to the screwing with a male connector of the line, while it is normally freely rotatable in the unscrewing direction. The male connector and/or the female connector can possibly be locked in rotation with respect to the body in the unscrewing direction, only following a positive command.

The present invention relates, in general, to medical fluid lines, for example, hemodialysis lines, chemotherapy lines and the like.
Such fluid lines are normally fitted along their path with connectors for the connection between the various components of the line: typically male and female luer lock connectors and the like. Accidental disengagement or due to incorrect maneuvers between these connectors can result in possible serious consequences for the patients connected during the use of the line.
The object of the present invention is to provide a safe and effective solution to this problem, whilst at the same time being practical and functional.
The invention will now be described in detail with reference to the accompanying drawings, provided purely by way of non-limiting example, in which:
FIG. 1 is a schematic perspective view of a fitting for medical fluid lines according to a first embodiment of the invention,
FIG. 2 is an elevational side view of the fitting,
Referring initially to FIGS. 1 to 7, the fitting according to a first embodiment of the invention is indicated with I and is tubular. It comprises an outer hollow body 1 of generally cylindrical shape, within which a male connector 2 of the luer lock type and analogues, and a female fitting 3 of the luer lock type and analogues are coaxially housed in an opposite condition.
The connectors 2 and 3 are rotatably mounted relative to the body 1 and to each another, with the limitations which will be discussed, and have a generally conventional shape. In detail, the male connector 2 comprises an inner tubular element 4 with a conical outer surface protruding from one end of the body 1, and an internally threaded outer hollow element 5, which extends towards the inside of the body 1 with a hollow appendage 6.
The female connector 3 consists of an externally threaded tubular element 7 with a conical inner surface, protruding from the other end of the body 1 and integrally formed with an appendage 8 terminating with a shank 9 rotatably inserted within the hollow appendage 6 of the male connector 2.
