Lifeline
A Mechanical CPR Device for
Sudden Cardiac Arrests.
Sudden Cardiac Arrests.
Problem Statement
How can we assist bystanders, first responders and law enforcement to increase survival rate in out-of-hospital cardiac arrest patients- a national public health crisis.
Experts agree that many of the deaths caused by SCA are preventable and that available technology, if appropriately applied, could reduce them significantly at a relatively low cost. The aim of this project is to develop a product system that would sustain life until advanced care is available for the SCA patient.
Research
Ideation
Ideation Sketches
Form Development and Design Iterations for:
- quick positioning of the device on the patient’s chest.
- Optimal User Interface for intuitive operation by untrained users/ bystanders.
- Arrangement of internal parts (screen, battery. buttons)
Functional Refinement
The new design uses a push type tubular solenoid for actuating the mechanical compression. The solenoid can be programmed to adjust the compression rate and depth.
- This decreases the overall size of the device making it more compact for storage.
- Low gravity center (<2inch), avoid toppling and hurting patients when moving at a high speed.
- Efficient CPR with smaller compression depth.
- Quicker to operate because the height of the suction cup does not need to be adjusted.
Physical Prototyping
Ergonomic deliberations to fit patients of all sizes.
Human Factors Evaluation
User testing to evaluate the functionality of the form and user interface.
