Luer Lock Fitting Views
The present invention is related to Luer-Lock fittings for medical infusion/transfusion lines, of the type comprising a tubular body having at one end a Luer cone connector coaxially surrounded by a substantially cup-like innerly threaded attachment element, and a detachable cap sealingly connected axially over said Luer cone connector.
The object of the present invention is to provide a Luer-Lock fitting of the type set forth in the above, which allows the sterilizing operation to be carried out in a more convenient and efficient way, enabling the treatment gas to flow over almost the entire outer operative surface of the Luer cone connector, with a simple, functional and cheap construction.
Referring initially to FIG. 1, reference numeral 1 generally designates a Luer-Lock fitting for medical infusion/transfusion lines, comprising a unitary body of moulded plastic material 2 defining at one end a first outer Luer cone connector 3, intended to be coupled within the terminal end of a flexible hose, not shown in the drawings, and defining at the other end a second outer Luer cone connector 4.
But for the annular enlarged portion 12, the cap 8 has an inner transverse section which is slightly larger than the outer transverse section of the Luer cone connector 4, whereby between the inner surface of the former and the outer surface of the latter an annular interspace 13 is defined, which opens towards the filtering membrane 10. This annular interspace 13 allows efficient sterilization practically of the entire operative outer surface of the Luer cone connector 4, by means of a sterilizing gas supplied within the Luer-Lock fitting 1 through the connector 3.
