[A multifunctional anesthesia device: the K circuit].
A practical versatile anaesthesia device is described. An electrical pump provides room air to carry anaesthetic vapours. O2 can also be added if desired. Energy is supplied either by built-in batteries (12 volts = autonomy 6 hours) or external electric mains (12-30 volts or 220 alternative volts). The optimal recommended anaesthetic circuit is the Modified D Mapleson Circuit for economy in oxygen and anaesthetic vapours (for an adult only 6 l are needed). A non-rebreathing circuit can also be used: so draw-over ventilation or the use of an auto-inflating bag are possible when no electric power is available. If mechanically controlled ventilation is necessary, a specific ventilator can be adapted. This apparatus has already been manufactured and is very practical on the battle field or in developing countries.
