Problem Statement
There are more than 350,000 out-of-hospital cardiac arrests annually in the US alone and more than 35,000 cases annually in Canada. Anyone who experiences it has a 10% survival rate.
​
This is mostly because of having to wait for the arrival of medical emergency personnel and using suboptimal manual compressions at best to aid the patient in the meantime.
​
Studies with immediate defibrillation and CPR have shown up to 60% survival rate 1 year after cardiac arrest.
​
The current state of the art is the LUCAS CPR, which provides immediate chest compression but it is bulky, not suitable for large patients, and costs over $20,000 - a hefty price for all parties involved.
​
We had the end goal of creating a consumer CPR machine that is affordable, universal form fitting, and ergonomic. We built 'CPR Lifeline' to be just that.
​
Due to the innovation, this product has received the National Award in the James Dyson International Design Competition.
LIFELINE
The new design uses an internal scotch yoke mechanism for actuating the mechanical compression due to its uniform torque distribution and symmetric sinusoidal motion:
​
-
This decreases the overall size of the device making it more compact for storage.
-
Low gravity center (<2 inch), avoid toppling and hurting patients when moving at a high speed.
-
Efficient CPR with required compression depth.
-
Quicker to operate because the height of the microfiber pad does not need to be adjusted.
​
Because of the adjustable strap, any large patient can fit in as well, which is a critical aspect.
