Abstract: A vessel for safe handling of substances and having a first connection member through which the interior of the vessel is accessible by a device, e.g., an injection syringe, for removing or adding material thereto. At least a part of the vessel is expandable and contractable. The vessel is further provided with a second connection member, which is interconnected or interconnectable with the first connection inside the vessel. The second connection member is connectable to a further vessel outside the vessel, so that substance can be transferred directly from the injection syringe to said further vessel via the first and second connection members.

Abstract: A vessel for receiving fluid includes a flexible part having a closed end and an opening at its opposite end, and a rigid protective cover, the edges of the opening in the flexible part being attached to the rigid cover in a manner such that the inside of the flexible part and the inside of the cover define a closed interior space, the flexible part being capable of being drawn up against the inside of the protective cover upon evacuation of the interior space whereby the flexible part is received within the protective cover. A connection member is provided on the outside of the protective cover, the connection member having a bore therethrough and a perforatable, resilient, self-sealing membrane extending across the bore, through which membrane a puncturing member may be inserted for removing material from or adding material to the interior space.

Abstract: The present invention discloses a device for introducing soft, short, catheter-cannula into a blood vessel. The device comprises a puncturing member and a connection member arranged at the rear end of the catheter cannula remote from the blood vessel. The device is easy to handle and the insertion of the needle, the catheter and the introducer is made in a single step.

Abstract: A container for the sterile storage and dispensing of a catheter intended for insertion into a blood vessel is provided with an outlet opening for dispensing the catheter therethrough and has rotatable means for feeding the catheter out through said outlet and indicating means operatively connected to the feeding means for indicating the length of catheter dispensed through the outlet.
