Assistive CPR Device

CPR is an acronym for Cardiopulmonary Resuscitation, an emergency procedure that is used to preserve brain function through artificially circulating the blood through the body. Conducting CPR is a physically demanding procedure that requires special training. The purpose of this project is to make CPR simpler and more accessible to individuals without the necessary strength or skill.

Background
CPR is an important life saving technique for victims who can not breath as well as those suffering form cardiac arrest. In statistics posted by the American Heart Association, having a bystander who can perform CPR improves the victims survival rate by almost 45 percent.

With 350,000 Cardiac arrests happening outside of the hospital every year, if CPR became available to those individuals unable to perform it and simplified for those not properly trained many more lives could be saved.

120CCs design team has acquired a CPR training mannequin to use for testing both prototype and final designs. Additionally, 120CCs will be using a volunteer to test if the design will provide mechanical assistance for weaker individuals.

Specifications
The Assistive CPR Device needs to meet certain specifications in order to be both practical and usable for emergency situations.


 * The device must be compliant with American Heart Association Guidelines.
 * The device must be able to compress the chest minimum of 5cm to maximum of 6cm.
 * The device should use force multiplication to help physically weaker individual to apply necessary force to compress the chest to a depth of minimum 5cm and maximum 6cm.
 * The device should be portable and easily stored for quick access and use during an emergency.

Base Board Lever Design
During the initial stages of brainstorming, our advisor provided us with a lever design where the individual would lay down on a baseboard to act as a counter balance for out lever. Thus allowing for an individual to have mechanical advantage when providing compression on the CPR Training mannequin. Although this was a simple design that helped narrow our own designs, having to move the patient onto the supporting platform in order to provide chest compression proved to be a major design flaw.

Abdulrahman Provided a second iteration of the Base board lever design that did not require a base to provide leverage to the patient and proved to be exceptionally portable with its simplicity.

Rotational Mechanism Design
The Rotational Mechanism Design provided by Josh Sewell utilized a hand cranking mechanism that would rapidly raise and lower the piston to provide compression on the patient. Turning the cranks with your arms would allow for the piston to provide 100-120 compressions per minute and utilize little force outside of your own physical endurance. Unfortunately the design was ultimately scrapped due to its complexity and inability to be portable.

Dual Fulcrum Design
Ahmed provided the design for a dual fulcrum assistant CPR Device. The second fulcrum would provide the force necessary for the patient to receive the necessary compression while maintaining a lever arm that would be accessible to a person in a wheel chair or with other limiting mobility. The simplicity of the design also lends to the ability to break down and be stored effectively or carried.
