User Interface
The user interface consists of an LCD, two rotary dials, two LEDs, and a membrane switch.
(See figure 1 for a representation these components.) The rotary dials are used to adjust the vacuum
level for each canister. The membrane switch provides user functions to control the smoke evacuator
on/off, volume reset, empty tank, vacuum system on/off, IV pole up, and IV pole down. Four additional
variable controls are located adjacent to the LCD. These functions change based on the screen which
is being shown at the time. Two LEDs are provided to indicate when either the smoke evacuator or
vacuum systems are active. The fluid volume level in each canister is display on a monochrome LCD,
which is positioned on a 360 deg swivel mounted above the user interface panel. A speaker is provided
to give audio feedback to the user.
