The MultiCircuit System. 1. Description of a device providing several Mapleson functions.
A device which provides for analogues of the Mapleson A, D and E anaesthetic breathing circuits in a compact and reasonably robust form is described. It incorporates a single lever for switching between Mapleson modes and uses a Heidbrink valve in the same way as the familiar CO2 absorbers. The breathing hose attachment points are similar to those on the CIG (BOC) Mark 3 absorber. This allows use with standard breathing tubes for non-coaxial purposes and, with the Mera F attachment, provides a coaxial circuit. Anaesthetic gas scavenging facilities are incorporated.
