DRE MVP Portable Ventilator

General Conditions

• Supply Pressure:
• Specified connection 4 bar medical air or Oxygen
• Working Range 3.5 to 8 BarG specified range which is the typical pressure delivered by 4 bar and 7 bar pipelines
• 2.8 to 10 BarG shall cause no safety hazard in single faulty condition
• Supply Quality: Clean Dry medical grade Air/Oxygen
• Gas Supply Temperature : 10°C to 40°C
• Filtration Required within Ventilator: 40 Micron or better
• Environmental Temperature storage and transport : -5°C to 50°C
• Transport Temperature : -18 °C to 60°C
• Environmental Temperature operating : 10°C to 40°C

Flow Control

• Flow Range: 0.1 to 1 Litre per second, +/-10% of set value
• Adjustment Range: Rotary Control 300° +/- 5°
• Graduation 0.25, 0.25, 0.75, 1.0; control will be non-linear

On Timer

• Timing Range : 0.25 to 2.5 seconds, +/- 10% of set value
• Adjustment Range: Rotary control 300° +/- 5°
• Graduation 0.25, 0.5, 1.0, 1.5, 2.0, 2.5; control will be non-linear

Input Fittings

• Input fitting to Ventilator will be a BSP threaded port.

System On/Off Control

• Type of Operator : 1⁄4 Twist bi-stable control knob with on/off indicator symbols

System Pressure Regulator

• This is supplied pre-set and shall NOT be user adjustable without removing the cover of the unit using tools.
• This is a safety feature to prevent excessive pressure in a single failure mode.

Airway Manometer

• Respiratory manometer with a range of -20 to 100 cmH2O
• Major graduations at increments of 10 cmH2O stating the value
• Minor graduations at increments of 2 cmH2O without numbers

Materials

• All materials will be compatible with air and oxygen.
• No animal tissues or derivatives thereof are to be used in the device or its manufacturing process.

Patient Valve

• Connection to breathing circuit connections 22mm with 15mm internal female taper.
• Integral pre-set pressure limiting safety valve 60 cmH2O ± 2.5 cmH2O.

Usability

• The four rotary controls will include:
• On/Off
• Inspiratory Flow
• Inspiratory Time
• Expiratory Time
• The controls will enable a constant flow during the inspiratory phase and infinite variability of I:E settings within the range of the controls.
