Portable CO2 Blending Device for Hyperventilation Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current devices for treating hyperventilation are not portable, require significant patient cooperation, and cannot automatically regulate CO2 levels in inhaled air to prevent hyperventilation syndrome, especially for panic disorder patients, and are not suitable for self-treatment outside clinical settings.
Innovation Solution
A portable device with a by-pass element, valves, and a blending vessel that measures and adjusts CO2 and O2 levels in inhaled and exhaled air separately, using a CO2 vessel and optionally an O2 vessel to regulate the CO2 content of inhaled air, ensuring the CO2 levels are maintained within a normal range to prevent hyperventilation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing devices for treating hyperventilation are used, then CO2 treatment effects can be achieved, but the devices are not portable and require significant patient cooperation and medical supervision
Solution Approach 1:
The device enables patients to independently monitor and adjust their CO2 levels through automatic sensing and controlled delivery, eliminating the need for continuous medical supervision and complex patient cooperation. The system self-regulates by sensing end-tidal CO2 and automatically adjusting inhalation from the CO2 reservoir.
Solution Approach 2:
The patent replaces manual operation and patient cooperation with electronic sensing and automated control systems. CO2 sensors, microprocessors, and automated valve systems substitute for the mechanical/manual operations required by previous devices.
2Reliability
If existing devices for treating hyperventilation are used, then CO2 treatment effects can be achieved, but the devices are large and not portable
Solution Approach 1:
The device integrates multiple functional components into a compact, nested structure where the CO2 reservoir, sensing elements, flow control valves, and power supply are arranged in space-efficient configurations that fit within a portable form factor suitable for patient carry.
Solution Approach 2:
The patent combines previously separate functions (CO2 storage, CO2 sensing, flow control, and power supply) into a single integrated portable unit, merging multiple subsystems into one cohesive device that maintains treatment effectiveness while reducing overall size.
3Productivity
If existing devices for treating hyperventilation are used, then temporary symptom relief can be achieved, but they cannot automatically regulate CO2 levels to prevent hyperventilation syndrome
Solution Approach 1:
The device incorporates CO2 sensors that continuously monitor end-tidal CO2 levels and provide feedback to a control system, which automatically adjusts the rate and amount of CO2 delivered to the patient, enabling dynamic prevention rather than just temporary relief.
Solution Approach 2:
The system proactively regulates CO2 levels before hyperventilation syndrome fully develops by continuously monitoring physiological parameters and adjusting CO2 delivery in advance, preventing the condition rather than merely treating symptoms after they occur.
4Reliability
If existing devices for treating hyperventilation are used, then treatment can be provided, but they require significant medical supervision and are not suitable for self-treatment
Solution Approach 1:
The device incorporates automated safety monitoring, alarm systems, and self-regulating CO2 delivery mechanisms that enable safe self-treatment without requiring continuous medical supervision, while maintaining treatment reliability through built-in physiological monitoring.
Solution Approach 2:
Electronic sensing, microprocessor control, and automated safety systems replace the need for manual medical supervision, substituting human oversight with intelligent automated systems that monitor treatment safety and alert medical personnel only when intervention is actually needed.

AI summary
The subject matter of the application is a device for adjustment and/or regulation of the C02, carbon dioxide content of the inhaled air. Device based on the invention where a C02 vessel 30 is connected to the CO2 input aperture (22) - a measuring tool (15) determining the CO2 content of the exhaled air is connected to the exhaled air pipe (11), - the output aperture of the measuring tool (15) is connected to the input aperture of a control unit (50), - the output aperture of the control unit (50) is connected to the valve (28) adjusting the blending rate of blending vessel (20) and so adjusting the C02 content of the inhaled air.
