Abstract: Device for easily and simply coupling to the free end of a small tube (7) mounted on a transfusion needle an apparatus of the type used for coupling a syringe to a drug holding bottle. The device comprises a hollow shaped body (1) that can be coupled to the small tube (7). An axial passageway (13) in the body (1) is closed by a plug (5). A collar (2) shaped as the mouth of a conventional drug bottle projects from the body (1). The collar (2) extends axially and a continuous annular recess (3) is formed therein. The recess (3) has a profile and arrangment sized and shaped to allow for the teeth projecting from the resilient lugs of the apparatus to which the device is to be coupled to be inserted and locked therein.

Abstract: A body is provided with members for coupling it to one end of a bottle or the like. The body has a seat for housing the free end of a syringe, with a hole for allowing for the syringe needle to pass through. The free end of a syringe may be housed and threaded in the seat. On the side opposite surfaces of the body seat and at the syringe end provided for insertion in the seat, there are formed radially projecting longitudinal teeth and slanted resilient fins which are deflected by the teeth as the syringe is threaded to the body. The teeth abut against the fins, thereby preventing the syringe from being screwed off the body.

Abstract: In order to withdraw pharmaceutical products from sterile vials by means of a syringe, apparatus is used on one end of which a syringe possibly containing a liquid solvent is mounted and at the other end of which a seat is provided for housing the mouth of a vial. The syringe needle can puncture the rubber or similar stopper by which the vial is sealed, while the needle itself remains enclosed and protected by said apparatus. The invention relates to a device which, when the vial has been removed, can itself be housed in said apparatus seat to enable the needle to puncture a rubber stopper provided on the device, which is connected to one end of a cannula having for example mounted on its other end a needle for transfusion purposes. In this manner, the liquid can be discharged from the syringe while the needle remains enclosed and protected by the said apparatus.
