Nasal Delivery Flow Regulator for Carbon Dioxide Saline
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current nasal delivery methods for treating head ailments, such as rhinitis, conjunctivitis, the common cold, and sinusitis, often fail to provide effective and safe relief due to systemic side effects and limited duration of symptom relief.
Innovation Solution
A method involving a flow-regulating device that delivers a therapeutic non-inhaled dosage of saline fluid combined with carbon dioxide and an additional active component, at a controlled flow rate and duration, directly into the nasal cavity, while the patient refrains from inhaling, to enhance symptom relief and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional nasal delivery methods are used to treat head ailments, then symptom relief is achieved, but systemic side effects occur and duration of relief is limited
Solution Approach 1:
The patent applies local quality by delivering carbon dioxide and saline solution specifically to the nasal cavity through a nasal spray device, concentrating the therapeutic effect at the site of action rather than systemically. This localized delivery reduces systemic side effects while maintaining effective symptom relief duration through direct mucosal contact and absorption.
2Speed
If carbon dioxide and saline are delivered at high flow rates, then rapid symptom relief is achieved, but patient safety is compromised due to potential inhalation
Solution Approach 1:
The patent employs dynamics by using a flow-regulating device that dynamically controls the spray flow rate based on patient needs and response. The device can adjust flow parameters in real-time to maintain optimal delivery speed for rapid symptom relief while preventing excessive flow that could cause patient inhalation or discomfort, thus balancing speed and safety.
3Ease of operation
If conventional nasal delivery devices are used, then ease of operation is maintained, but therapeutic effectiveness is insufficient
Solution Approach 1:
The patent applies parameter changes by modifying key delivery parameters including flow rate, spray duration, and solution composition (carbon dioxide concentration, saline concentration) to optimize therapeutic effectiveness. These parameter adjustments are integrated into the device controls, allowing patients to easily adjust parameters while maintaining enhanced therapeutic effectiveness compared to conventional devices.

AI summary
Methods for treating ailments in a patient in need thereof includes the step of directing a therapeutic, non-inhaled dosage to at least one nasal cavity of the patient through a flow regulating device while the patient refrains from inhaling. The dosage includes (a) a saline fluid (b) a gas containing carbon dioxide and (c) at least one additional active component, wherein the therapeutic, non-inhaled dosage is delivered at a flow rate from 1 cc/sec to 20 cc/sec for a duration of 2 to 30 seconds.
