Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The limited availability of hyperbaric oxygen chambers and the challenges of treating COVID-19 patients with hypoxemia, as existing chambers are not only scarce but also pose a risk to medical staff due to potential viral contamination, and current ventilators fail to provide sufficient oxygenation.
Innovation Solution
Repurposing commercial aircraft to create mobile hyperbaric oxygen therapy units by pressurizing the cabin to deliver high concentrations of oxygen using existing emergency oxygen systems, nasal cannulas, and face or head coverings, allowing for simultaneous treatment of multiple patients while minimizing contamination risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If commercial aircraft are repurposed as mobile hyperbaric oxygen therapy units, then the capacity for treating patients increases significantly, but the complexity of the system increases
Solution Approach 1:
The patent repurposes commercial aircraft, which were originally designed for transportation, into mobile hyperbaric oxygen therapy units. The aircraft's existing pressurization system, oxygen distribution network, and cabin structure are adapted for medical therapy, allowing one system to serve multiple functions (transportation and medical treatment). This universality principle enables significant increase in patient treatment capacity without requiring entirely new infrastructure.
Solution Approach 2:
The aircraft's existing emergency oxygen system is utilized to provide hyperbaric oxygen therapy. The cabin's built-in pressurization capability, oxygen tanks, and distribution pipes are repurposed for therapeutic purposes, allowing the system to serve itself rather than requiring completely separate equipment. This self-service approach reduces the need for additional complex infrastructure.
2Reliability
If traditional hyperbaric oxygen chambers are used, then effective oxygenation is provided, but the availability is limited and contamination risk exists
Solution Approach 1:
The patent transitions from stationary hyperbaric chambers to mobile aircraft-based therapy units. By moving the treatment capability into the third dimension of mobility and scalability, the system can serve multiple locations and accommodate numerous patients simultaneously. The aircraft cabin's large volume allows parallel treatment of many patients, fundamentally expanding treatment availability beyond what traditional chambers can provide.
Solution Approach 2:
The aircraft cabin is divided into multiple treatment zones with individual oxygen delivery systems for different patients. Each patient receives oxygen through separate nasal cannulas or face coverings, allowing simultaneous independent treatment of multiple patients. This segmentation enables the system to maintain reliability for each patient while dramatically increasing overall treatment capacity.
3Speed
If ventilators are used to treat hypoxemia, then respiration is increased, but sufficient oxygenation is not achieved
Solution Approach 1:
The patent changes the fundamental parameter of oxygen delivery by utilizing the aircraft's pressurization system to deliver oxygen at elevated partial pressures. Instead of merely increasing respiratory rate through ventilators, the system increases the concentration and pressure of oxygen available for absorption. This parameter change addresses the root cause of hypoxemia by improving oxygen availability rather than just breathing frequency.
Solution Approach 2:
The aircraft's pneumatic pressurization system, originally designed for cabin pressure control, is adapted to deliver hyperbaric oxygen therapy. The system uses pressure differentials and gas flow control to deliver high-concentration oxygen to patients, leveraging pneumatic principles to achieve effective oxygenation that ventilators alone cannot provide.
