For Plasma TCI, Propofol (Marsh), Propofol (Schnider), and Remifentanil (Minto) are available.
For Effect-site TCI, Propofol (Schnider) and Remifentanil (Minto) are available.
Dose unit
• The flow rate (mL/h) can be automatically calculated based on the dose units such as
μ
g/kg/min. The calculated contents of the
flow rate can be checked on the screen.
Easy-to-read display
• With a 4.3 inch (10.9 cm) colour LCD, clear and precise visibility has been achieved.
• The operation indicator allows the operation/stop/alarm status to be easily recognised.
• The internal battery charge and level indicator is displayed on the LCD with 5 bars.

: Only if the VTBI setting function is enabled (Default: disabled)
• The Occlusion alarm detection sensitivity level can be changed according to the condition of use.
• The Flow Rate/VTBI Volume Judgment alarm works as a safety function to prevent the normal mode operation if the flow rate is
equal to or more than the VTBI. (Default: disabled)
Additional safety functions
• The keypad lock function disables any switch operations after being set to prevent any operational errors or inadvertent
operations. (Except for Start switch, Power switch and Back/Mute switch (for operation to release the keypad lock).)
User-friendly shape and structure
• With a unit weight of approx. 2.0 kg, the carrying burden is reduced, and allows for stable installation with the pole clamp
included.
• The rounded-cornered body is easy to clean even when drug solution has adhered.
Dual power supply system
• Dual power supply system with AC power and internal battery
• The internal battery can provide approx. 8 hours of continuous operation for solution delivery at a flow rate of 5 mL/h at
temperature of 25°C, with a fully-charged new battery.
• The internal battery can be charged to approx. 80% in 3 hours.
• The sub-battery is used for a Power Failure alarm in case both power supplies are lost.
