Solution Overview

Problem

Current nasal irrigation devices lack a practical, hand-held solution that combines gravity, pressure, and suction delivery methods, and do not offer a powered mechanism for safe and effective nasal irrigation, leading to inefficiencies and discomfort during use.

Innovation Solution

A hand-held nasal irrigation device with a source of saline solution, an effluent receptacle, a nasal interface, fluid passageways, and a switch and valve assembly that utilizes gravity and powered suction to deliver saline solution, providing a controlled and gentle irrigation while collecting effluent for easy disposal, adaptable to various nasal dimensions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If gravity-based nasal irrigation devices are used, then the device structure is simple, but the irrigation effectiveness and control are insufficient

Engineering Contradiction:
Improvedevice structureVSAvoidirrigation effectiveness
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The patent combines gravity-based delivery with powered suction mechanisms into a single integrated device. The device includes both a saline solution delivery system utilizing gravity and a powered suction system with a vacuum source, merging two different irrigation approaches into one unified system that leverages the advantages of both methods for more effective nasal cavity irrigation.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent incorporates a powered suction mechanism using pneumatic principles, where a vacuum source creates negative pressure to actively draw saline solution through the nasal cavity. This hydraulic and pneumatic system complements the passive gravity-based delivery, providing controlled and effective irrigation that overcomes the limitations of gravity alone.

Inventive Principle:
Principle #29Pneumatics and hydraulics

2Reliability

If powered suction mechanisms are added to nasal irrigation devices, then irrigation effectiveness improves, but device complexity and size increase

Engineering Contradiction:
Improveirrigation effectivenessVSAvoiddevice structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent divides the device into distinct functional modules: a saline solution delivery system and a powered suction system. Each module operates independently but is integrated within a single hand-held device. The suction system includes separate components such as a vacuum source, fluid passageways, and control mechanisms, allowing for modular design that manages complexity while maintaining effectiveness.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The device incorporates dynamic control elements including a switch and valve assembly that allows users to control and regulate the suction mechanism. This dynamic control system enables adjustment of irrigation parameters during use, providing adaptability and ease of operation despite the added complexity of powered components.

Inventive Principle:
Principle #15Dynamics

3Ease of operation

If hand-held design is implemented, then ease of operation improves, but device stability and control precision decrease

Engineering Contradiction:
ImproveconvenienceVSAvoidcontrol precision
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent incorporates control mechanisms including switches and valves that provide user feedback and control over the suction mechanism. The switch and valve assembly allows users to regulate the powered suction, providing a degree of precision control in a hand-held format. This feedback control system helps maintain reliability and control precision despite the portable design.

Inventive Principle:
Principle #23Feedback

AI summary

Systems and methods for nasal irrigation are provided in which a nasal irrigation device includes a source of saline, an effluent receptacle, a nasal interface, a vacuum source, a fluid passageway to communicate the source of saline with the effluent receptacle through the nasal interface and a nasal cavity of the user, and a switch and valve assembly for selectively controlling the vacuum source and flow of the saline through the fluid passageway. The saline source is disposed relative to the device to provide gravitational inducement of saline to the nasal interface in engagement to the device user's nostrils. A combination of the gravitational inducement and the relative vacuum from the effluent receptacle generates a fluid flow for irrigating, cleansing and massaging the nasal cavity and ostia of the user. The entire device is assembled as a hand-held device for convenient lifting and disposal against the user's nostrils.
