The National Agency for Science and Engineering Infrastructure has produced the first made in Nigeria ventilators.
The development is aimed at combating the COVID-19 disease in the country.
Ventilator is a vital equipment in the treatment of coronavirus patients.
NASENI has equally produced mobile sprayers, which are to be used to disinfect Nigerian cities and homes.
A notice by NASENI spokesman, Segun Ayeoyenikan, disclosed that Minister of Science and Technology, Dr Ogbonnaya Onu, would unveil the devices on Tuesday (today).
The Federal Government, through the Federal Ministry of Finance, recently begged for ventilators from an American billionaire.
The government eventually withdrew the plea, which was widely seen as a national embarrassment by citizens of Nigeria.
