Abstract: An apparatus and system for transferring a liquid, such as an anesthetic, from the outlet port of a reservoir to a machine while effectively and conveniently minimizing the release of anesthetic. In one embodiment, the apparatus and system can include a first valve movable between a first position and a second position; a first housing surrounding the first valve; a second valve slidably connected to the first valve and movable between a third position and a fourth position; and a second housing which surrounds the second valve; wherein the apparatus defines a first opening, a second opening, and a receiver passage between the first and second openings. In another embodiment, a movable plunger can be slidably connected to the second valve.

Abstract: A vaporizer includes a thermally conductive anesthetic container and a temperature sensor positioned in the container and in the liquid anesthetic. A breathing-gas delivery tube has a delivery end positioned in the liquid anesthetic at least about 5 mm beneath the top surface of the liquid anesthetic. A heater is positioned outside the container. Control circuitry is configured to receive signals from the temperature sensor and is connected to the heater in order to cause the heater to maintain the temperature of the anesthetic above a predetermined temperature. A method of vaporizing inhalation anesthetic is also provided.

Abstract: An apparatus and system for transferring a liquid, such as a liquid anesthetic, from a reservoir to a machine while minimizing the release of the liquid to the surrounding environment. The apparatus can include a frame member defining a frame passage extending from a first end of the frame member to a second end of the frame member and a nozzle connected to the frame member. The nozzle can be moveable between a first position and a second position relative to the frame member, and can define a plug member configured to block the second end of the frame passage when the nozzle is in the first position. The apparatus can further include a biasing member connected to the frame member and the nozzle.

Abstract: The present invention may be embodied as a device for selectively opening or closing an anesthetic reservoir, the device having a first component adaptable to a reservoir and a second component adaptable to a vaporizer. The first component may have a base, a nozzle, and a through-hole. The second component may have a support member with a knob for engaging the through-hole of the first component and preventing liquid from flowing from the through-hole. The first and second components may be threaded to engage with each other such that when the components are twisted relative to each other, the knob may move toward or away from the through-hole to prevent or allow liquid flow.

Abstract: An anesthetic container and closure for transferring anesthesia from a container to a vaporizer. A hinged closure member is moveable between an open position and a closed position by a receiving member of a vaporizer when the anesthetic container is attached to the vaporizer for transfer of liquid anesthetic from the anesthetic container to the vaporizer. The hinged closure member is moved to the closed position upon withdrawal of the receiving member.

Abstract: A device for containing a volatile anesthetic and an anesthetic agent delivery system. The device may include a bottle closure, which may be attached to an anesthetic bottle until it is time for the anesthetic to be transferred to a vaporizer. A membrane may be used to seal the opening in order to prevent the anesthetic from leaving the reservoir until it is desired to fill the vaporizer. In order to protect the membrane a cap and a cap support may be placed on the reservoir so as to cover the membrane. The container may further include a connecting surface on the cap support or the reservoir, the connecting surface being connectable to a vaporizer. The system includes a vaporizer having a side slotted tube needle that is able to pierce the membrane and through which the liquid anesthetic agent and/or vapor may pass from the reservoir to the vaporizer. A method for transferring a liquid anesthetic from a container to a vaporizer.
