CONTEXT

Existing Products in market - 

Vanderbilt University -  Mechanical Engineers at Vanderbilt University designed a somewhat similar product with using a windshield wiper motor to deliver high torque on the ambu-bag. 

The breakthrough was to repurpose an everyday syringe into an oxygen-powered ram. A valve directs oxygen into the syringe which squeezes a self-inflating air container delivering 400ml of air directly to the patients’ lungs. A two port valve and ‘throw-over’ mechanism cause the ram to reciprocate.

In order to save and conserve oxygen, the waste gas is fed into a reservoir to enrich the patient's air supply.

The ventilator is driven and controlled entirely from the hospital oxygen supply without the need for electricity.

The number of cycles per minute, volume of air delivered, and air pressure can all be controlled according to patient’s needs.

Our Journey

 It all started in August 2020 when we took Innovation By Design course under Prof. B.K Chakravarthy and Prof. Anil Gupta. In this course we learned about seven concerns of innovation which form the backbone of innovation process. These concerns are namely cause, context, comprehension, check, conception, crafting and connection. Our goal was to design a ventilator that would be affordable, easy to use and could be operated at home in case of emergency. In this journey we came across different kinds of ventilators which were designed to fulfill the same end goal. We studied their design and learned from the drawbacks of their design and tried our best to improve it. we understood the importance of systematic innovation going from cause to crafting and then to connection which included getting feedback from end user.  Overall the learning process was quite intriguing and creative. Thanks to our professors for making this course a creative and fun way of learning.
