Abstract
A gas-tight closure device for the connecting ends of tubes for biomedical fluid-transporting apparatus, particularly haemodialysis lines, which are sterilized by means of sterilizing gas, includes a tubular connector defining an internal Luer cone and a cap which is fitted to the connector. The hermetic closure of the connector by the cap is effected by means of complementary conical surfaces for the mutual force-coupling of the outer lateral wall of the connector and the inner wall of the cap.
Claims6
A gas-tight closure device for the connecting ends of tubes for biomedical fluid-transporting apparatus, particularly but not exclusively haemodialysis lines, which are sterilised by means of sterilising gas, comprising a tubular connector having an end surface, an internal Luer cone and an outer lateral wall provided with external screw-engagement projections, a cap having an inner wall which is fitted to the tubular connector, and hermetic sealing means between the cap an the tubular connector, wherein the hermetic sealing means are only situated outside the Luer cone of the connector and include complementary conical surfaces defined by the outer lateral wall of the connector and the inner wall of the cap for mutual sealing engagement.
