  • Page 38: Diva Supply Module

    Function Description Zeus Figure 14 Optical and electrical interfaces DIVA supply module The supply module is not anaesthetic-specific. It holds the metering modules and provides the interface to the anaesthetic machine. The supply module principally comprises 2/2-way valves to control the propellant gas and the saturated vapour.
  • Page 39 Zeus Function Description Figure 15 Supply module gas flow diagram For safety reasons (risk of explosion), the propellant gas used is AIR. The propellant gas flows through the non-return valve (30) and the volume (170 mL) to the pressure reducer (71). There the pressure is stabilised at 2.4 bar relative.
  • Page 40 Function Description Zeus The distributor block heater (4), the mixing chamber heater (88) and the satu- rated vapour line heater (61) prevent anaesthetic condensing in the outlet of the supply module. The heat output is regulated with the temperature sensors (65 and 66) and the temperature sensor of the mixing chamber heater.

  • Page 41: Diva Metering Module

    Zeus Function Description The actuation valves for the left and right side metering modules are con- trolled by a valve driver. When the microcontroller is in Reset mode the power is cut to all valves. To minimise the power loss from the valves, the voltage is switched down from 18 V to 7 V by means of an integrated circuit (step-down regulator) once the valves have been actuated.
  • Page 42 Function Description Zeus Figure 17 Metering module gas flow diagram When the metering module is connected and locked in place, the closure valves (25) and (72) are mechanically opened. The module detector (38) detects the connected and locked metering module. The pressure sensor (21) measures the input pressure of the propellant gas.
  • Page 43 Zeus Function Description The injection valve (9 and 8) injects a defined quantity of liquid anaesthetic into the evaporator chamber (7) as specified. In the evaporator chamber (7) the liquid anaesthetic is converted into saturated vapour (100% anaesthetic). The evaporator chamber heater (68) is regulated by way of the temperature sensor (69).
  • Page 44 Function Description Zeus Figure 18 Block diagram of the Metering Module PCB The valves are controlled by a valve driver. When the microcontroller is in Reset mode the power is cut to all valves. To minimise the power loss from the valves, the voltage is switched down from 18 V to 7 V by means of an integrated circuit (step-down regulator) once the valves have been actuated.
  • Page 45 Zeus Function Description The Metering Module PCB has a Debug interface which can be addressed optionally by way of a plug connector or via an IR transceiver. Another IR-interface (Safety) receives pulses from the supply module. If those pulses are not received, e.g. because of an error in the supply module, all the valves of the metering module are set to a safe state.
