Handheld CPR Device with Foam Housing and Metronome
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Laypersons and first responders find it challenging to perform effective chest compressions during CPR at the recommended rate of 100 compressions per minute due to difficulty in maintaining the required rhythm and force, especially under duress.
Innovation Solution
A handheld CPR assist device with a non-slip handle and pre-programmed verbal instructions, combined with a deformable housing filled with foam, helps users maintain the correct posture and applies consistent force, guiding them through the recommended compression rate and depth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If laypersons perform chest compressions manually without assistance, then they can provide CPR assistance, but they struggle to maintain the correct rate of 100 compressions per minute and consistent force
Solution Approach 1:
The device incorporates a metronome mechanism that provides auditory feedback to guide the user through the compression rhythm. The metronome emits beeps at intervals that correspond to the recommended compression rate of 100 per minute, helping users maintain the correct timing and rhythm during CPR performance
Solution Approach 2:
The device uses a spring-loaded mechanism with foam that automatically returns to its original position after compression, eliminating the need for manual resetting. The spring system self-resets between compressions, reducing the operational burden on the user and allowing them to focus on maintaining the correct compression rate and force
2Reliability
If users apply sufficient force and depth to chest compressions, then quality of CPR improves, but it becomes more difficult to maintain the required rhythm and consistency under duress
Solution Approach 1:
The device incorporates a spring-loaded mechanism with foam that is pre-compressed to provide the necessary force and depth for effective chest compressions. The spring system is pre-configured to deliver consistent compression force, ensuring reliable CPR quality without requiring the user to manually regulate force application
Solution Approach 2:
The metronome provides continuous auditory feedback that reinforces the correct compression rhythm and timing. This feedback loop helps users maintain consistent rhythm and force application even under stressful conditions, improving the reliability of CPR quality
3Ease of operation
If the device includes metronome and spring-loaded mechanisms, then ease of performing compressions improves, but device complexity increases
Solution Approach 1:
The device merges the metronome timing mechanism with the spring-loaded compression mechanism into a single integrated unit. The housing combines both functions, allowing the user to simultaneously receive auditory timing guidance and mechanical compression assistance through one device rather than multiple separate components
Solution Approach 2:
The device is designed as a disposable unit with a single-use foam component and non-reusable spring mechanism. This approach simplifies the overall device design by eliminating the need for complex cleaning, sterilization, or maintenance systems, while still providing the necessary ease of operation during emergency use
