it is a very good development. However, the professional ventilator is far different from this one. But this is good for first aid purpose. There are lot of parameters that have to be monitored while applying ventilator. Ventilators are operated in several modes, one of them is patient triggered. Other one is ventilator triggered. Need to monitor the temperature of the oxygen going in the patient lung. Percentage of oxygen is also very important. There are many ventilators on youtube, but one has to be very careful in applying on critical patients. However this could be useful for patients on transit in ambulance etc. etc... but surely not for those who are in very critical conditions
The "Real Engineering" youtube channel did a very good critique of this kind of ventilator. Understanding the needs of the medical staff is super important for engineers looking to help by mass producing low cost ventilators.

Hi Team, Just a suggestion in case if that can help. To reduce the circuitry cost, we might be able to use a transistor-based astable multivibrator which consists of only 2 very cheap transistors, few resistors, and capacitors. The output can drive a relay that can switch the direction of current flow which can, in turn, change the motor direction.
every university is saying they are doing one, but none is being used in hospital, FDA did not relax their qualification parameters, so FDA should come forward to appreciate open source society and help them infact to realise a producible model.
@@jamescrud agreed with due regards, better their efforts are made use, if this is the state in developed nations with world class medical facilities, imagine about nations like india where only 1 vent is available for 4000 'infected people' , anything which helps is ok
Great Idea. Now build ten stations along a wall. Use one motor running a long shaft (in bearing blocks) at a standard motor speed behind the stations. At each "ventilator" position there would be a cam on the shaft to control the speed and volume of each breath. Cuts out all electronics and suitable for rural installations.
An even "Redder Neck" idea: Buy a foot operated inflator/pump and clear hosepipe from your hardware store; ventilator masks from the drugstore; use a geared motor (eg wiper motor or similar) and mount an eccentric disk onto its shaft to operate the pump. I'll try building one this week and post it...
A nice initial Engineering Breadboard prototype. I hope they have created the Risk Management Plan, listed all safety issues found from research of all sources, databases, and the competitors equipment safety instructions, created the Customer Requirements Database, initial House of Quality is complete, and validated the Customer Requirements, and System Requirements Specifications (system, hardware, and software) already. All plans reviewed and approved for Development, Design, Reliability, Configuration Management, Quality Assurance, Verification & Validation, Software, Procurement, Production, Testing, and Quality Control. Next is the Initial Design review of all output by expert customers and independent experienced engineers. Then on to design the Engineering Model after repeating and refining everything as well as creating Fault Tree Analysis, Failure Mode Effect analyses for system, hardware, and software and incorporate all the design changes and validate them, and reliability plan and demonstration initiated. Then comprehensive Design Review again. Then the Pre-Pilot Run Model repeating and refining everything using production parts and methods but engineers building. Design Review again. Then the actual Production Pilot Run using production processes and personnel and then clinical trials, and compliance testing. Then final Design Review. Then file 510k with FDA and filings with other regulatory bodies, and receive consent to distribute. Then Production Release with all production processes and supply chain activated. Continuous monitoring of fielded units for data analysis, trending, safety oversight, and CAPA process. So another two days and they'll be satisfying all the needed vents worldwide ;) Oh, almost forgot ... I assume they have done all the design activities under FDA GMPs and ISO compliances including all the required documented processes, training, and validated systems, successful independent audits, and methods. Because to do otherwise would endanger lives and be foolish. Right?
Everything is simple enough. But these bag valve designs assumes theres a bag valve available. If we are making these for emergency deployment, itll mean we have exhausted all other safer approved methods of ventilation, then we need to assume the situation is way beyond walking up to the the hospitals pharmacy and buying a bag valve and building the rest. Any ideas that considers the non availability of anything medically approved?
GM ? GM is only building a few hundred complicated Ventec Life Systems ventilators in April. "GM plans to eventually make 10,000 powered ventilators per month, but will start with “hundreds” in April, according to Ventec." Ford and GE Healthcare says it expects to be able to build 1,500 of them by the end of April, 12,000 by the end of May, and 50,000 by July, eventually reaching a rate of 30,000 per month. Tesla is also looking at how to build ventilators through Medtronic, buying some from China already to distribute.

Most corona virus disease patients need CPAP + O2. (Google that). Not an artificial lung, don't they? (Can somebody who knows for sure reply) My idea: Grab a large air pump to make a positive flow for multiple patients and distribute into a hospital with a hose. There is O2 enough as hospitals have a large concentrator. They just need a possitive air distribution and maybe ajust the pressure per patient if possible.
That's quite right.. the invasive ventilation (intubation) is only necessary when the condition is so advanced that the patient is no longer able to breathe unassisted.. in which case the prognosis is extremely poor anyway.. CPAP plus O2 at an early stage will buy valuable time... For the bodies natural defense.
