Abstract: A supplemental air diffusion device is shaped and configured to be attached to the body or clothing of a patient below the head and deliver supplemental air toward the mouth and nose of the patient. The supplemental air diffusion device includes a frustroconicoidal air diffusion body that has a smaller inlet opening at an inlet end and an enlarged diffusion opening at a diffusion end. An air inlet stem is integrally attached to the air diffusion body and includes a plurality of ribs and/or recesses for releasably locking a female connector of an air supply hose over the inlet stem. A pair of spaced-apart slits are provided through a flange extending laterally from an outer surface of the air diffusion device. Initially separate accessory patient attachment clamps are looped through the slits and provide for releasable attachment of the air diffusion device to a patient's clothing.

Abstract: Food serving pans made from heat conductive materials include a gasket positioned over a flange to protect fingers from heat or cold, improve gripping ability, seal against countertops of food serving tables, and/or protect paint or non stick coating from chipping off the flange. The food pan is made from aluminum or other highly heat conductive material. The gasket comprises silicone or other heat resistant and insulating elastomer. A food serving system includes one or more food pans and a food serving table. The food pans maintain food at a desired temperature by efficiently transferring heat or cold from the serving table while the gasket seals against a countertop of the serving table. The gasket can be provided in a kit of differently sized and/or shaped gaskets so as to fit over differently sized and/or shaped pan flanges. A user can install and replace the gasket as needed.

Abstract: Food serving pans made from a heat conductive materials include a gasket protecting a flange to protect fingers from heat or cold, improve gripping ability, seal against countertops of food serving tables, and protect paint or nonstick coating from chipping off the flange. The food serving pan is made from aluminum or other highly heat conductive material. The gasket comprises silicone, other elastomer, or other heat resistant and insulating material. The gasket includes a circumferential sealing ridge and finger gripping recess. A food serving system includes one or more food pans and food serving table. The food serving pans help maintain food at a desired temperature by efficiently transferring heat or cold from the serving table while sealing the interface between the flange and the countertop of the serving table. The interface between the gasket and flange prevents buildup of food or debris, maintaining cleanliness during repeated use and cleaning cycles.

Abstract: Food serving pans made from a high heat conductive material include a gasket covering at least a portion of the flange in order to protect a person's fingers from heat or cold, improve gripping ability, provide a seal against a counter top of a food serving table, and protect paint or non stick coating from chipping off the flange. The food serving pan is made from aluminum or other highly heat conductive material. The gasket comprises silicone, other elastomer, or other heat resistant and insulating material. The gasket includes a circumferential sealing ridge and a finger gripping recess. A food serving system includes one or more food pans and a food serving table. The food serving pans help maintain food contained therein at a desired temperature by efficiently transferring heat or cold from the serving table while sealing the interface between the flange and the counter top of the serving table.
