COVID-19 Emergency Ventilator

In response to the COVID-19 outbreak, Imperial’s experts in medical device design (bioengineering) – and a clinician treating infected patients – have designed an emergency ventilator that can be built to meet MHRA and FDA requirements using generic parts.  JAMVENT provides a simple, low-cost solution to ventilator shortages worldwide, particularly for health services in developing countries. Plus the robust design also makes it suitable for long term use beyond current COVID-19 needs.

The design document for the JAMVENT ventilator can be requested by those wishing to develop ventilators for their local healthcare providers and includes a list of parts and a software spec.

We welcome enquiries from health organisations, manufacturers and donors interested in working with us to take JAMVENT from design to manufacture.

 

Design benefits

  • Long term use – not specific to the COVID-19 crisis
  • Easy to manufacture from low cost components (estimated at around £1,500 in the UK)
  • Does not require specific pressure transducers or solenoids
  • Parts can be sourced from various manufacturers – avoiding supply-chain bottlenecks
  • No specialist or medical supply chain components – and no balloons
  • Simple electronics
  • Doesn’t require gas to drive it – unlike some others – which is critical where gas supply is limited.
  • Employs fluid mechanical design principles

 

Ventilator design meets clinicians needs

  • PEEP controllable electronically
  • Pressure Regulated Volume Control (PRVC) mode
  • Supports spontaneous breath
  • Maintains PEEP during suctioning

Performance evidence

Evidence that the JAMVENT prototype can perform to MHRA and ISO 80601 tests can be downloaded here.

It also highlights PRVC and spontaneous mode performance and how it can maintain PEEP during suctioning – critical functions of ICU ventilators for COVID-19 patients.
