Nasal Respiratory Assembly With Rotatable Intake Ports
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current nasal respiratory assemblies for delivering therapeutic treatments and medications via CPAP systems cause discomfort, lead to barotrauma, and inefficient medication delivery due to direct pressurized gas flow into nasal cavities, resulting in discomfort, medication loss, and potential skin irritation.
Innovation Solution
A nasal respiratory assembly with a mask featuring two rotatable intake ports and one or more rotatable medication delivery ports positioned to avoid direct delivery into nasal cavities, along with a ventilation hose equipped with medication delivery ports for close proximity medication administration, ensuring a more natural breathing pattern and effective treatment delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pressurized gas is delivered directly into the nasal cavities, then the therapeutic treatment can be delivered effectively, but the patient experiences discomfort, barotrauma, and unnatural breathing patterns
Solution Approach 1:
The patent introduces a face-contacting surface as an intermediary component between the pressurized gas source and the patient's nasal cavities. This surface creates a ventilation chamber that allows gas to be delivered without direct impingement on the nasal passages, thereby maintaining therapeutic effectiveness while reducing discomfort and barotrauma risks
Solution Approach 2:
The mask is divided into distinct functional zones: a face-contacting surface that creates a seal, a ventilation chamber for gas accumulation, and controlled delivery ports. This segmentation allows the pressurized gas to be distributed and controlled before reaching the patient, reducing direct high-velocity impact on nasal cavities
2Device complexity
If medication is delivered through the pressurized gas stream from a distance, then the system remains simple, but medication is lost and dosage is diminished
Solution Approach 1:
The face-contacting surface acts as an intermediary platform that allows medication to be delivered close to the patient's nasal cavities without requiring complex long-distance delivery systems. Medication can be administered through the ventilation chamber or directly onto the face-contacting surface, ensuring effective dosage delivery while maintaining system simplicity
Solution Approach 2:
The face-contacting surface and ventilation chamber are prepared in advance to receive and concentrate medication before it reaches the patient. This preliminary positioning ensures that medication is delivered at the optimal location and concentration, preventing loss during transit
3Quantity of substance
If the mask is removed to deliver medication, then full medication dosage can be administered, but the patient suffers from poor oxygenation
Solution Approach 1:
The face-contacting surface and ventilation chamber serve multiple functions: they maintain the pressurized gas seal for oxygenation while also providing a platform for medication delivery. This multi-functionality allows both oxygenation and medication administration to occur simultaneously without removing the mask
Solution Approach 2:
The ventilation chamber serves as an intermediary space where both pressurized gas for oxygenation and medication can coexist and be delivered together. This eliminates the need to choose between oxygenation and medication delivery, as both can occur through the same interface
4Reliability
If the face-contacting portion applies sufficient force to achieve a gas tight seal, then the seal is effective, but excessive pressure causes discomfort and skin irritation
Solution Approach 1:
The face-contacting surface is designed as a flexible component that can conform to various facial contours while distributing pressure evenly. This flexibility maintains an effective gas tight seal without concentrating excessive force on small areas, thereby preventing skin irritation and discomfort
Solution Approach 2:
The face-contacting surface has varying local properties: softer materials in areas prone to skin irritation and firmer sections where seal integrity is critical. This localized quality optimization ensures effective sealing while minimizing harmful pressure effects on sensitive facial areas

AI summary
The present invention is a nasal respiratory assembly and methods of using the same wherein the assembly comprises a mask, a ventilator hose and a strap. The mask has a top surface, a base, an exhaust port having a one-way valve and two rotatable intake ports. The hose has a first end and a second end adapted to be received by the first and second intake ports, and at least a third end to connect to the ventilator. The hose and/or the mask further contain a rotatable medication delivery port to allow treatment delivery in close proximity to the patient.; The rotatable intake ports are located on either side of the mask so that the pressurized air is not delivered directly into the patient's nasal cavities.
