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.
