The S-Vent has been designed to be produced in areas with limited manufacturing capabilities during the Covid-19 Pandemic. It requires no machined, injection moulded or 3D printed parts and could be manufactured in any shed, workshop or field hospital. It uses a medically certified manual ventilation bag (MVB), which can be connected to an oxygen supply if needed, and the S-Vent provides the input to compress the bag and provide pressurised air/oxygen to the patient.
It has been desiged in collaboration with respiritory consultants who have helped in prioritising the key functions required based on the MHRA guidlines for emergency ventilators*. It is not been designed to replace a high tech ventilator but as a low tech-solution where no other ventilator may be available.
It can provide the following features:
Everything about the design is free to take away and use, there are no restriciton on how many anyone can make or if you want to modify it. The main purpose is to share the design as much as possible so that it can be used or improved with feedback.
*The S-Vent has been designed to be simple to manufacture while providing as many functions as possible to help provide ventilation to a patient. It has been designed by Dr Tom Burton who has over 10 years experience in Medical Device design, manufacture and compliance and is a Senior Systems Engineer at McLaren Applied. However, the S-Vent has not yet been approved for clinical use. I have tried to make the design as safe and easy to use as possible but the target use of the device is where no other option is available. In the coming few days I hope to trial the device with a lung simulator and it has already completed a 36 hour run-time test.
