CARTRIDGES OF LIQUID ANAESTHETIC AND VAPORISER

摘要

The invention relates to a system comprising a cartridge and vaporiser. The vaporiser is a universal vaporiser since it can use various different liquid anaesthetic materials instead of just one. The cartridges can be disposable cartridges that are disposed of after use instead of being refilled by the end user. Said cartridges can include one or more memory devices therein, such that information relating to the cartridge can be communicated to the vaporiser, such as the type of liquid anaesthetic material contained therein. The cartridge/vaporiser system can be controlled to enable the vaporiser to update the information in the cartridge memory, such as the amount of liquid anaesthetic material used during a particular cartridge use session. The vaporiser can maintain a virtual operating log with information relating to the operation of the vaporizer. The information contained in the virtual operating log relating to the operation of a vaporizer with respect to the supply of anaesthetic vapour to a particular patient can be communicated to a storage location outside of the vaporizer, where it is stored together with other related medical registers.
