MERLIN is a microprocessor-controlled ventilator designed by vets for vets. We have done away with conventional pressurised gas driving mechanisms and use a precisely controlled piston that can accurately deliver volumes in the range 1ml to 800mls.
Merlin can be pressure-cycled, volume cycled or time-cycled and the inspiratory and expiratory times are fully and independently variable without the need to re-adjust after changes in flow rates or volumes. A pressure control allows you to set the maximum allowable pressure during volume cycling or the target pressure during pressure cycling.
A further added feature is the inspiratory assist control that will tune the ventilator to your patient during recovery and so assist weaning from the ventilator. On the front of the unit is a large easily readable display that shows all of your selected parameters. These parameters are continuously updated reflecting every adjustment made.
We believe Merlin is truly innovative in being the first veterinary ventilator to calculate and display the compliance of the patient being ventilated.

As a mechanical ventilation device, this is definitely a veterinary ventilation innovation! With high-performance turbine drive, R420 ventilator no longer needs driven gas! It’s a good solution to gas consumption problem of traditional ventilators. In addition, its easy-to-use working modes and comprehensive monitoring of animal ventilation state can ensure safe ventilation.
Turbo Drive: Electronically driven by a high-performance turbine, no more driven gas
Precise ventilation:Minimum tidal volume down to 4 mL，more friendly to tiny animals.
Smart preset: Once inputting animal weight, smart respiratory parameters can be called up.
Guard “breathing” safety: Accurate and continuous monitoring of respiratory status, such as airway pressure – time chart, minute volume, EtCO2, and etc.
Multiple alarms: Multiple alarms and clear handling prompts ensure the safety of mechanical ventilation
PEEP function: Help veterinarians solve low SpO2 problems during surgery
Auto system leak test：Graphical guidance for quick start
Remote control of inspiratory hold: During a CT scan of the chest or abdomen, help the animal to hold the inspiration and complete the CT scan
Now incorporates alerts and alarms for ventilation status • Patient disconnect • Over-pressure • Apnoea • Valve disconnect or failure
Measurement of inspiratory time and respiratory rate
Select-and-commit entry to prevent false changes
Easy and intuitive to use
Compact, rugged unit
Internal battery for portable/mobile use

Safe, simple, pressurecycled ventilation for small animals
The SAV04 is an enhanced version of the long-standing SAV03 ventilator and uses the same principles of simple, pressure-cycled ventilation.
In the redevelopment of the ventilator, features have been added to improve patient control and to improve ventilation status feedback. For example, there is now an automatic over-pressure alarm that will sound if the target pressure is exceeded by 8cm. There is also an alarm if the patient becomes disconnected from the ventilator, or if no back-pressure is detected during the inspiratory phase.
These alarms are designed to be informative and are accompanied by explanatory text on the main screen. In addition, an audible beep is produced on every successful breath. Both this beep and the alarm beeps can be individually silenced if required. There is a new valve design to accompany the new ventilator and this has two major benefits.
Firstly, the valve can be automatically zeroed on any other SAV04 machine allowing valves to be swapped or replaced easily.
Secondly, a larger orifice in the exit port of the valve means the port can now support larger animals. The 12mm diameter exit orifice will now allow unrestricted expiration in animals up to 40kg.
It must be remembered the principle of operation is still based around a T-piece, so proportionately higher fresh gas flow rates will be required. However, with the advent of oxygen generators, running such a system on 8-10L is feasible for short-term or emergency use. The new display now provides more information to the user. A central rising bar graph shows the pressure in the patient’s airway, enabling quick assessments to be made on system and/or ET tube leaks. Each inspiratory period is now measured and displayed on the screen as is the measured respiratory rate.
The new SAV04 provides a simple, yet safe, way to ventilate your smaller, most vulnerable patients.
