Abstract:
The present invention relates to multi-purpose vials and a process of making them. The multi-purpose vials may be used in hypodermic administrations of drug or as part of a drug delivery system.
Abstract:
A system is provided for the delivery of a liquid anaesthetic agent to an anaesthetic vaporizer (20). The system includes a supply container (24) having a spout (40) defining an outlet through which the agent can be discharged. A reservoir is provided in the vaporizer (20) for holding the agent, and a receiving station (22) is provided on the vaporizer (20) for receiving the container spout (40). The agent flows from the container (24) through the spout (40) by gravity into the reservoir. The container spout (40) is located at the station (22) to define the maximum liquid level of the agent in the vaporizer (20) when gas flow into the container (24) is blocked by the rising level of the liquid agent. In one embodiment, a frangible seal (50) is provided in the container (24), an outlet valve (96) is provided in the container (24), and an inlet valve (132) is provided in the receiving station (22). The valves (96, 132) open automatically as the container (24) is inserted into the receiving station (22) of the vaporizer (20). Also, the container spout (40) is preferably movable relative to a collar (36) so as to automatically effect rupture of the frangible membrane (50) as the container (24) is inserted into the receiving station (22) of the vaporizer (20).

Abstract:
A formed, filled, and sealed flexible container is provided with an attached port assembly. The container is formed from film folded to define opposing sidewalls which are sealed to define a chamber for sterile fluid. A hollow, tubular port member is provided with a V-shaped saddle and is sealed to the bottom of the container. The film at the bottom of the container is received in the saddle. A unique shoulder is defined by the tubular port member. The film is sealed to the shoulder and to the saddle of the port member. A hollow penetrator element is slidably disposed within the port member and is movable between a retracted position and an advanced position to puncture the film whereby fluid can flow out of the container. Internal formations are provided to guide and to limit the movement of the penetrator element. The container film may be provided with a crease along the bottom of the container.
