Building Low-cost Ventilators to Fight COVID-19

A Sphinx Worldbiz Limited & TimeTooth Technologies Initiative

About the Initiative

With the rising numbers of people falling prey to the deadly Coronavirus Disease (COVID-19), it has become imperative to prevent any more people getting affected. The Governments and Healthcare authorities across the world are concerned about the prevention and control of the disease. Sincere research is going on around the world to stop the mayhem for good. The hospitals are running out ventilators and other important medical equipment. To reverse the course of this pandemic and to combat this situation with a regular supply of high-quality medical grade equipment, Sphinx Worldbiz Limited and TimeTooth Technologies have solemnly come together to pledge their contributions for the cause in a philanthropic initiative of designing and developing a Low-cost Mechanical Ventilator.

Open Source Tech Innovation and Philanthropy

The design of the ventilator is a step ahead to join India’s Open-Source initiative following the footsteps of many international universities and other organisations to help the humanity at large. Open source ventilator designs will be available for any manufacturer who wants to build low-cost ventilators at scale. It is a step ahead for both healthcare and the mankind for but not limited to the times of Coronavirus pandemic.

The Ventilator to be developed is going to be highly efficient for its purpose as much as they are ergonomic and economic. Their USP is therefore-
LOW-COST, QUICK TO BUILD, PRODUCED IN MASS healthcare equipment. Which is the need of the hour.

LOW-COST,
QUICK TO BUILD,
PRODUCED IN MASS
ventilators

Sphinx Worldbiz offers full support of their technical resources towards manufacturing of the prototype for validation of the state-of-the-art medical equipment. TimeTooth Technologies is contributing through developing the overall design. The holistic designing of the ventilator is estimated to be 50,000 USD.

TimeTooth Technologies calls for fundraiser support for the project as this is a crucial time for pulling all stops to fight against COVID-19. This is a voluntary effort and not for profit which Sphinx also considers its prime social responsibility.

Design Approach- The Differentiators

Our prototype services combine with TimeTooth designs will make up state-of-the-art medical grade equipment. With the ventilators project our teams are determined to save many lives suffering from respiratory challenges due to the Coronavirus infection. Hospitals across the world may need a larger volume of Mechanical Ventilators soon and at a low cost. We will be ready with support.

Like us, several other ventilators development-based initiatives have begun but face many challenges. Our differentiators are that we are ready to take on all the challenges and provide ergonomic solutions to them.

Some of the Challenges With These Initiatives Are:

Sphinx Worldbiz and TimeTooth Approach to These Challenges

Medical grade development to address the appropriate Qualification Test Schedule.

Durable design for COVID-19 patient duty cycles (5 – 14 days at a stretch).

Operational modes designed especially for COVID-19.

Predominantly Indian sourcing and manufacturing

Low cost
