Assisted CPR

RISD MIT Product Design & Development, Spring 2019


Product Design & Development

This joint studio between Mechanical Engineering, Industrial Design, and Sloan MBA students teaches modern tools and methods for product design and development. The cornerstone is a project in which teams of students conceive, design, and prototype a physical product. The following project was evaluated and selected using HBR's Real-Win-Worth It screening.

Executive Summary

The HeartJoules mission is to save the lives of more cardiac arrest patients by making CPR treatment easier and less physically taxing. To achieve our mission, we developed the Resuscitation Assistance Mechanism (RAM), the first device to mechanically assist with chest compression during CPR. In order to meet the unique needs of each possible use case, the RAM serves as platform technology. Leveraging bus modular architecture, the RAM attaches to multiple handle types tailored to the specific needs of each market segment. As a platform technology, the RAM can be licensed by medical device companies and customized to meet the needs of their customers. To date, our team developed two working prototypes (RAM v1 and RAM v2), informed by over 20 user interviews, over 25 concepts, and various sketch models. The following reports comprise the information and decisions made at our 5-week and 12-week checkpoints.

Progress Report 1 contains customer needs and competitive analysis, potential markets, most promising concepts considered, concept models, and assessment of failure modes and risks.

Progress Report 2 provides a detailed overview of the device and its specifications (Section 1). Next, we provide information on the process and milestones, as well as key decisions and the justification for those decisions (Section 2). We further summarize key due diligence that we conducted, including sustainability, financial, and patent reviews (Section 3). We conclude with an overview of our remaining steps, risks to be mitigated prior to our final design review, and recommended next steps for future commercialization (Section 4).

Mission Statement

To save the lives of more cardiac arrest patients by making CPR treatment easier and less physically taxing.

Future Work

The RAM is a first-in-class mechanical device that enables professional and lay users to perform manual CPR correctly and efficiently. The design of the device offers users improved ergonomics when compared to traditional hand-on-hand CPR, reducing both fatigue and discomfort. Additionally, the device makes an audible “click” loudly indicating to the user when a chest compression was forceful enough and deep enough.

As of the end of this course in May 2019, we designed this product such that the cost of production is significantly lower than existing ACCs, delivered two functioning prototypes with a budget of $1000, and have a patent pending for the device.
