Abstract: The device includes a syringe and an apparatus for coupling the syringe to a drug holding bottle and the like, the apparatus defining an enclosed chamber wherein there is housed a needle to be coupled to the syringe and the free end of which is arranged is front of a tightness resilient member located at a seat adapted to receive the mouth of the bottle, the syringe being firmly and fixedly clamped, in a tight way, in a syringe seat formed in the apparatus.

Abstract: The invention relates to an apparatus for connecting a bottle containing a medicament to a syringe the needle of which is housed in a closed chamber defined by the apparatus and from which the needle can be made to emerge by sliding the separate constituent parts of the appartus along each other. To prevent the needle from emerging from the chamber when no bottle is housed in the appropriate seat provided in the apparatus, there extends from one of the parts of the apparatus an elongated flexible appendix having at least one protuberance which projects into the seat and against which the bottle presses when inserted into the seat, so bending the appendix outwards. In front of the free end of the appendix there is provided a stop tooth projecting from that consituent part of the apparatus which is projecting from that constituent part of the apparatus which is mobile along the first part and extends totally around the seat.

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.

Abstract: The invention relates to a device to one end of which a syringe can be connected and to the other end of which the mouth or opening of a bottle containing a drug or medicine can be connected. The device comprises a closed chamber having enclosed therein a needle which is in connection with the syringe. Members are provided by means of which the mouth or opening of the bottle is steadily connected to the device and means enabling the needle to perforate a seal plug and then a small rubber plug mounted on the bottle only when the device is blocked onto the bottle so that in any case it cannot be disconnected therefrom. Such a device can be disconnected from the bottle only after the needle has been caused to reenter the closed chamber, so as to prevent any possible dripping of the liquid outside of the device.
