Design Specifications

The MVM ventilator is inspired by the Manley ventilator, which was developed by Roger Manley in 1961. The ventilator includes the following main components: Connection to oxygen and air supply, sintered filters, gas blender, four differential pressure sensors, air/oxygen delivery proportional valve, adjustable pressure limiting valve, negative pressure relief valve, oxygen sensor, spirometer, braking system (connected to the tracheal tube), condensate trap, silicone membrane filter, expiration valve, and PEEP valve.  The control system regulates the air/oxygen delivery proportional valve and the expiration valve based on the selected programmed respiratory cycle. The following accessories are needed: Gas blender (GENTEC GMX120 or equivalent) and catheter mount (DEAS 1510TG, DEAS 22xxDV, or equivalent). The control system regulates the air/oxygen delivery proportional valve and the expiration valve based on the selected programmed respiratory cycle.

Manufacturer Specified Performance Parameters

The MVM ventilator was designed in response to the COVID-19 pandemic and thus the designers focused on the following targets: (1) Small number of components, (2) ease of procurement, (3) simplicity of construction, (4) low cost, (5) convenience of deployment, (6) customizability, (7) reliability, and (8) limited oxygen consumption. 

Vetted Performance Status

The ventilator has passed all of the ISO 60601 tests for basic safety and essential performance.

Safety

For safety, the manufacturer specifies the following operational ranges: Temperatures from 10 to 40 degrees Celsius, and in relative humidities from 10-95%, at a maximum altitude of 3000 meters.

Complementary Technical Systems

The manufacturer offers additional accessories, including a gas blender for mixing medical air and oxygen before the inlet to the mechanical ventilator.

Academic Research and References

Compliance with regulations
