Abstract: A connector is provided for mounting on an anesthetic vaporizer to connect the inlet of the vaporizer with a discharge port of a container of liquid anesthetic. The connector includes a first coupling attachable to the vaporizer and defining a first passage communicating at one end with the vaporizer inlet. A second coupling is attachable to the container and defines a second passage communicating at one end with the container discharge port. A third passage defined by one of the couplings and communicates with one of the first and second passages. A combination valve and mounting structure is cooperatively defined by the couplings to accommodate pivoting of the second coupling to a closed position occluding the first and second passages, to a raised fill position establishing communication between the first and second passages, and to a lowered drain position in which the first and second passages communicate through the third passage.

Abstract: The present invention relates to a control system for use with an automated intravenous drug and fluid infusion system having plural pumping channels that operate independently for intravenously infusing drugs and fluid. The pumping channels are controlled by a microprocessor-based host controller that monitors each of the channels concurrently. In an exemplary embodiment, the system functions include identifying the particular drug that is to be pumped through a channel, preventing priming of a channel unless verification is provided that the channel is not connected to a patient and initiating the priming of each of the pumping channels independently.
