Anaesthetic apparatus, Dameca MPII, with OMV vaporisator

There is no information available for this product.


General information

Basic anaesthetic unit (gas-driven and draw-over system), used in conditions where an oxygen supply is not  readily available or is unreliable.

Anaesthetic machine use for surgical procedures in emergencies.

The anaesthetic machine can operate as a draw-over or a gas-driven system.


When fresh gas (O2) is unavailable or supply is irregular, ambient air can be used as "fresh gas" (using the draw-over system).


Gas delivery system: With oxygen using gas-driven system


- Oxygen gas supplied in cylinders enters via the reduction valve then proceeds to the rotameter box (2), the draw-over valve (7), the vaporizer (8) and finally to the patient breathing circuit. When using oxygen the lever for the draw-over valve (7) must be in the horizontal position.


Gas delivery system: Without oxygen using draw over system


- When oxygen is unavailable, the lever for the draw-over valve is placed in the vertical position, ambient air from the built-in reservoir (10) is then used as  a main carrier to evaporate the anaesthetic agent in the vaporizer (8).


- During inspiration, the air is sucked from the built-in reservoir through the vaporizer; the mixed gas is then fed to the patient through a self-expending bag and Ambu valve.


OMV 50 VAPORISER (Oxford miniature vaporizer)

- A partial temperature-compensated, calibrated vaporizer. Low internal resistance allows ambient air to be used as a gas carrier, it can also be used with a continuous gas flow.


-Aesthetic agent: halothane


-Content: 50ml




- Driving gas: O2–N2O


- Driving gas pressure: kPa


- Rotameter tubes: 1 to 10 litres/min


- Low-flow regulation: 0.1 to 2 litres/min


- Accuracy: ±1.9% IF and  0.6% FS


- Note: an MP-2 does not have a slave regulator valve


- Bypass valve: approximately 45 litres per minute at 400kPa


- Reservoir: volume 750ml


STAND with 4 wheels
