A connection nipple for providing fluid communication with the interior of the container, such as for example a blood bag or the like. The connection nipple comprises a hollow tubular member having a first end which is adapted to be sealingly inserted within the blood bag and a second open end disposed externally of the blood bag. A circumferential rib member is provided circumferentially about the hollow tubular member intermediate the first and second ends. The circumferential rib has a cross-section which tapers substantially to a point to define a connection line about the circumference of the hollow tubular member. A releasable sealing sleeve member is integrally connected to the hollow tubular member in the vicinity of the connection line, and sealing surrounds and completely encloses the second open end of the tubular member to thereby prevent fluid communication with the interior of the blood bag through the second open end. The releasable sealing sleeve member is adapted to be disconnected from the hollow tubular member to expose the second end of the hollow tubular member by twisting of the sleeve member relative to the tubular member to cause the sleeve to break along the connection line.
4926915 - Ampul - Owned by Stella KG Werner Deussen (Eltville,DE)
An ampul comprising a container having a reduced neck which supports an integral closure part that is removable by tearing away frangible portions. The neck can be sealingly applied over the seating cone of a hypodermic syringe whereby the syringe and ampul are firmly joined as one unit. The ampul is preferably produced as a single piece of a thermoplastic synthetic such as polypropylene whereby the ampul neck has sufficient elastic ductility to be elastically expanded by applying it to the seating cone of the syringe, thereby to assure a firm coherence. To permit air to enter to container when suctioning off the ampul contents, the ampul neck has on its inside an axial ventilating means.
A port and closure assembly is provided. The closure includes a cap that cooperates with the port to produce a friction fit. The cap and port are hermetically sealed together by a coating. The coating provides a method of determining if the closure has been opened.
An apparatus and method for the rapid infusion of circulatory supportive fluid or blood is disclosed. The apparatus includes an enclosed housing for retaining the fluid prior to infusion, means for warming the fluid, means for circulating the fluid within the housing, means for inhibiting cellular damage of the fluid, means for permitting oxygenation of the fluid, and means for transfusing the fluid to the patient. The method includes the steps of providing an apparatus as described above, supplying it with circulatory supportive fluid or blood, warming the blood, and infusing it into a patient's vein at a rate of up to 3,000 or more ml. per minute. The invention permits exceedingly rapid blood infusion at a single site, utilizing an apparatus which is easy to set up and very simple to use.
