Solution Overview

Problem

Current treatments for COPD and pulmonary hypertension often rely on external nitric oxide sources or medications that have limited impact on airflow obstruction and vascular resistance, and there is a need for non-drug therapy to enhance nitric oxide levels in the lungs, especially in home healthcare settings where external sources are not applicable.

Innovation Solution

A device that detects the respiration cycle and applies acoustic or vibratory stimuli at the resonant frequency of the paranasal sinus to enhance nitric oxide flow into the lungs during inhalation, without requiring external nitric oxide sources, using a detector and stimulator controlled by a controller to optimize nitric oxide enrichment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If external nitric oxide sources are used to enhance nitric oxide levels in the lungs, then nitric oxide concentration in the alveoli is improved, but device complexity and applicability for home healthcare deteriorates

Engineering Contradiction:
Improvenitric oxide concentration in alveoliVSAvoidcomplexity of external nitric oxide delivery system
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The device enables the patient's own paranasal sinuses to serve as the nitric oxide source. The sinuses naturally produce and store nitric oxide, which is then released into the airway during breathing. This eliminates the need for external nitric oxide cylinders or generation systems, making the device suitable for home healthcare while maintaining effective nitric oxide delivery to the lungs.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The invention extracts and utilizes the nitric oxide already present in the patient's paranasal sinuses. By applying acoustic stimulation, the device enhances the release of endogenous nitric oxide from the sinuses into the airway, thereby obtaining the desired substance (nitric oxide) from within the body rather than from external sources.

Inventive Principle:
Principle #2Taking out (Extraction)

2Quantity of substance

If acoustic stimulation is applied continuously to enhance nitric oxide flow from paranasal sinuses, then nitric oxide concentration in inspired air is improved, but loss of nitric oxide during expiration deteriorates

Engineering Contradiction:
Improvenitric oxide concentration in inspired airVSAvoidnitric oxide washed out during expiration
Core Design Contradiction:
Quantity of substanceVSLoss of substance

Solution Approach 1:

The acoustic stimulation is applied periodically and synchronously with the patient's breathing cycle. The stimulator delivers acoustic energy during the inspiration phase when nitric oxide release is beneficial, and reduces or stops stimulation during expiration when nitric oxide would otherwise be washed out. This timing optimization maximizes nitric oxide delivery to the lungs while minimizing loss during exhalation.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The device incorporates sensors that detect the patient's breathing cycle (inspiration and expiration phases) and use this information to control the timing of acoustic stimulation. This feedback mechanism ensures the stimulator activates at the appropriate moment in the respiratory cycle, coordinating nitric oxide enhancement with the natural breathing pattern to prevent waste during expiration.

Inventive Principle:
Principle #23Feedback

3Productivity

If acoustic stimulation frequency is increased to improve sinus ventilation, then nitric oxide outflow from sinuses is improved, but nitric oxide concentration in inspired air deteriorates due to excessive washing out

AI summary

A device is provided for controlling the nitric oxide levels within the lungs of a subject. The device comprises a detector for detecting the respiration cycle of the subject and a stimulator for applying an acoustic or vibratory stimulus to the subject. The stimulator is controlled in dependence on the detected respiration cycle. In particular, acoustic stimulation may be provided at the onset of inspiration. In this way, the nitric oxide flow can be controlled in a way to ensure that the paranasal nitric oxide is nearly fully inspired. This provides a higher nitric oxide concentration in the lung/alveoli.
