Abstract: An anesthesia breathing circuit for connecting between an anesthesia delivery machine and a mask has an inspiratory tube, an expiratory tube, and a connection that allows the mask to communicate with both the inspiratory tube and the expiratory tube. The present invention resides in using a material which incorporates a scent-releasing agent to fabricate at least one element of the breathing circuit through which gas is fed to the mask from the anesthesia delivery machine. In one preferred embodiment, the scented element is a segment that may be coupled to conventional elements of an anesthesia breathing circuit so as to form a part of the inspiratory tube; the scented element can then be uncoupled when the scent is no longer desired.

Abstract: A wineglass having a bowl of depth D and a bottom region symmetrically disposed about a central axis is provided with a protrusion having a cental core, attaching to the bottom region of the bowl and terminating in a central core free end, and one or more ledges attached to the central core and positioned to form one or more wine-supporting ledge surfaces positioned intermediate between the central core free end and the bottom region of the bowl. The protrusion is disposed about the central axis and has a height H that is preferably between about 0.5 D<H<0.8 D. When the wineglass is swirled, the wine-supporting ledge surfaces serve to catch the wine and allow the wine to subsequently fall back, thus aerating the wine and enhancing the perceived bouquet. The protrusion can include a pedestal sized to aid in measuring a sample volume of wine.
