Standards for Ventillators

I don’t want to discourage anyone but here are the fact and fictions about ventilators. I have done some reading on ventilators out of curiosity as I am entrepreneur and 73 yrs old technocrat. I have developed many SPMs sold in India and abroad. We are always in hurry to make and publicize the product without understanding the subject. Even when we make a simple machine. We need to give consideration to, how it will work on field, what will be the working response of the components we bought out, what will be it's quality, how our vendors will provide service, how will we provide after sales services, whether we have sufficient work force in case of failure during warrantee, geological limit we can serve the machines etc etc, there are many factors. I was surprised to see videos of corporate like JK tyres and Mahindra. These were advance version of bicycle pump. Even a schoolboy made it and said price will be Rs. 250. Many NGOs and giants around the world are working on this for years. We have just woken up. All these Indian ventilators are JUGAD. It is not that simple as it appears. Medical science, electronics, engineering involved in it and need a software to run these machines. I think all those who have made these ventilators considering that it is bicycle pump. Yes, it is like that, but it is linked with human life and it is an intricate technology. Even present ventilators are not safe. Ventilators now being used are mainly called PPV (Positive Pressure Ventilator). NGOs are working on NPV (Negative Pressure Ventilator). Which is fixed from neck to abdomen and not on the mouth. In this case (NPV) patient can talk and medicines can be fed to him while he is on ventilator. Here the link to know about ventilators. https://hackaday.com/2020/03/25/ventilators-101-what-they-do-and-how-they-work/. My logical question where is the market after Covid19 is over? Surprise to note a gentleman who is asking here advice, did not thought of searching on net. The NGO named SUPERVASI from Thane, Maharashtra has made a NPV in India. In any case any ventilator cannot be priced a few thousands, it is a myth. Hardware for control panel to operate the machine l itself may cost around ₹50,000. Good luck to all who are thinking of making it. It seems, none of anyone who demonstrated ventilator on media not thought of control panel. Though I can make it. I will not because I don't see any potential in it after Covind 19 and looking at players around the world. I have worked with DRDO but do not have a good opinion. more
