Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current emergency medical devices, such as Automated External Defibrillators (AEDs), are ineffective in treating non-cardiac respiratory failures due to lack of oxygen therapy and invasive ventilation methods, which require trained professionals and are not accessible to minimally trained operators in out-of-hospital settings.
Innovation Solution
A compact system integrating an Airway and Ventilation device (AV) with a face mask, CO2 sensor, pressurized oxygen source, and Automated External Defibrillator (AED) that provides real-time feedback on CPR efficiency and oxygen flow, enabling non-invasive ventilation and defibrillation by minimally trained personnel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If non-invasive ventilation is provided using a face mask and pressurized oxygen source, then accessibility to oxygen therapy is improved for minimally trained operators, but device complexity increases due to integration of multiple components
Solution Approach 1:
The patent combines multiple emergency medical functions into a single integrated device: non-invasive ventilation delivery system with face mask, pressurized oxygen source, CO2 sensor for monitoring, CPR feedback mechanism, and AED defibrillation capability. This merging allows minimally trained operators to access comprehensive respiratory and cardiac emergency treatment without managing separate complex devices
Solution Approach 2:
The device is designed as a universal emergency medical system that can perform multiple functions: providing pressurized oxygen therapy, monitoring CO2 levels, guiding CPR through real-time feedback, and delivering defibrillation shocks. This multi-functionality enables a single device to address both respiratory failure and cardiac arrhythmia emergencies, improving accessibility while consolidating complexity into one unified system
2Reliability
If invasive ventilation methods are used, then treatment effectiveness is improved, but ease of operation deteriorates as trained professionals are required
Solution Approach 1:
The system incorporates automated monitoring and feedback mechanisms that enable minimally trained operators to effectively deliver ventilation therapy. The CO2 sensor automatically monitors treatment effectiveness and provides real-time feedback, allowing the device to self-regulate and guide the operator without requiring specialized medical training while maintaining treatment reliability
Solution Approach 2:
The device includes a CO2 sensor that continuously monitors the patient's respiratory status and provides real-time feedback to the operator. This feedback mechanism allows minimally trained users to adjust ventilation parameters based on objective measurements rather than requiring professional judgment, thereby maintaining treatment effectiveness while simplifying operation
3Ease of operation
If out-of-hospital settings are served, then accessibility to emergency treatment is improved, but reliability of treatment deteriorates due to lack of professional medical support
Solution Approach 1:
The device is designed to autonomously monitor treatment quality through integrated CO2 sensing and provide real-time feedback, enabling minimally trained operators in out-of-hospital settings to deliver reliable emergency care without professional medical support. The system self-regulates ventilation parameters and alerts operators to treatment effectiveness, ensuring quality care in remote locations
Solution Approach 2:
The patent replaces the need for professional medical judgment with automated electronic monitoring systems. The CO2 sensor and microprocessor-based control system objectively measure treatment effectiveness and guide therapy delivery, substituting mechanical/electronic systems for human expertise and thereby maintaining treatment reliability in settings without professional medical personnel

Data Source
AI summary
A system that includes both an Airway and Ventilation device (AV) and an Automated External Defibrillator (AED) device is described. The system allows minimally trained persons to operate it in emergency situations involving respiratory failure and/or cardiac arrhythmias. An integral part of the AV of the system is a face mask manufactured in two parts: a face attachment unit configured to attach to the patient's face and a mask body that is releasably connected to the face attachment unit by a quick release mechanism allowing quick removal of the mask body from the face attachment unit, leaving only the face attachment unit attached to the patients' face, in order to address urgencies such as vomiting. After vomiting ceases and is cleared, then the mask body may be reattached to continue ventilation.
