Storage vessel for diluent for anaesthetic - utilises latent heat of wax to maintain diluent at constant temp.

摘要

The diluent for an anaesthetic is stored in a vessel (2) and is maintained at a constant temp. by a latent heat storage device. The latent heat storage device consists of an outer vessel (3) with double walls and with the space between the walls being filled with thermal insulation. The outer vessel (3) is filled with a material, such as a wax, which melts at the same temp. as the required storage temp. of the diluent. Any change in ambient temp. causes the wax to melt or solidify so that the wax gains or releases latent heat without any change in the temp. of the wax. USE/ADVANTAGE -Storage of a diluent for an anaesthetic. The diluent is kept at a constant temp.
