<p>A medical substance (9, 92) is contained in a body (11, 82, 123) by a plug which (15, 67, 90, 122) is penetrated rather than removed in order to extract the substance in a sterile manner. The plug (15, 67, 90, 122) has a socket (23, 70, 91) open to the exterior and a connector (14, 60, 82, 120) has a screw threaded nose (22, 62, 95, 121) which engages therein, either by screwing into a complementary thread or by self tapping. The plug (15, 67, 122) may have a pre-cut slit (27, 68, 126) through it from the base of the socket (23, 70) and as the connector screws in a spigot (29, 64, 124) on its extremity works through the slit. A passage (20) through the spigot and nose is then available to the substance. When the connector is unscrewed, the slit closes up. Alternatively, the nose (95) may carry a hollow needle (96) which pierces its way through the plug (90). The plug may be a piston-seal (15, 90, 122) of a syringe or the cap (67) of a bottle (66). The connector may be a transfer device (83, 113) connectable to another body (81, 110) containing a substance to be mixed with the first substance before use.</p> |
