We have studied many projects around the world. And we finally select to concept and specificatinss calculation of MIT University (USA) and AmboVent 1690.108 (Israel). Both are project was support and approved by Governments. But we wil change the mechanical and electrical design which can be suitable for our situations and manufacturing conditions.

Our concept design (TNV Venticlattor using for emergency cases)

Our plan for this project:

  • Weeek 1 - From Apr. 1st to 7th: redesign and build the prototype
  • Weeek 2 From Apr. 7th to 14th: submit the prototype for doctors testing and approval for using in emergency cases. In the mean time, we redesign again for massive production.
  • Week 3 from Apr. 14th to 21th: To be ready for production.

On the other hand, we will keep updates information all projects around the world.!!
