Nasal Spray Device with Dynamic Control for Targeted Drug Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current treatments for non-infective nasal symptoms often face challenges in delivering targeted medication effectively due to the complexity of respiratory tract conditions and the difficulty in identifying precise causes, leading to inadequate relief of symptoms such as nasal congestion and inflammation.
Innovation Solution
A topical composition for nasal administration is formulated by combining a dry powder, including zinc or pharmaceutical salts, with an aqueous diluent at the time of administration, which may also include additional components like acetylcysteine, azelastine, xylitol, or probiotics, to manage non-infective nasal symptoms effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If systemic delivery routes such as oral or intravenous administration are used, then medication can be delivered to multiple locations, but the treatment becomes less targeted and may have more side effects
Solution Approach 1:
The nasal cavity is divided into multiple compartments (right and left nasal passages, superior and inferior turbinates) that can be independently targeted. The spray device allows selective deposition of medication into specific nasal regions by adjusting spray direction and intensity, enabling differentiated treatment of different nasal segments without affecting the entire nasal cavity or causing systemic effects.
2Ease of operation
If localized application of medications is used, then targeted delivery is improved, but the device complexity increases
Solution Approach 1:
The spray device incorporates adjustable parameters including spray angle, spray pressure, and pulse duration that can be dynamically modified during use. The device allows real-time adjustment of these parameters to adapt to different patient needs and nasal anatomies, providing targeted delivery without requiring a complex fixed mechanical structure. The controller enables dynamic optimization of spray characteristics for precise medication placement.
3Adaptability or versatility
If multiple conditions are present, then treatment complexity increases, but identifying precise causes becomes more difficult
Solution Approach 1:
The system incorporates feedback mechanisms where the controller receives input from sensors detecting nasal cavity conditions and adjusts spray parameters accordingly. The device can monitor factors such as nasal congestion level, mucosal moisture, and patient response in real-time, using this feedback to automatically optimize medication delivery parameters and adapt treatment to the specific combination of conditions present, making cause identification and treatment adjustment more accurate.

AI summary
A method of managing non-infective nasal symptoms may include formulating a topical composition for nasal administration. The formulation may include zinc, acetylcysteine, azelastine, one or more probiotics, or a combination thereof. The formulation may also include additional ingredients such as a steroid, poloxamers, or xylitol. Ingredients of the topical composition may be provided in a dry powder format within a capsule for combining with an aqueous diluent at the time of administration. The topical composition may be administered nasally.
