Portable Nasal Irrigation Device with Integrated Compressor and Hermetic Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional nasal douche devices are cumbersome, require external connections for operation, and lack hermetic sealing, making them non-portable and difficult to clean and disinfect, which poses infection risks.
Innovation Solution
A portable nasal washing device with integrated components, hermetic sealing, rechargeable batteries, and a dual-function battery charger that supports the device during recharging, allowing autonomous use without external connections, featuring a compressor group with a pump and electric motor for generating compressed air, and a nebulizing system for delivering liquid to the nasal cavities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If traditional nasal douche devices are connected to external equipment (compressor, electric circuit), then they can generate sufficient compressed air for nebulization, but they become cumbersome, bulky, and require external connections, reducing portability
Solution Approach 1:
The patent combines the compressor, electric motor, battery, and nebulization components into a single integrated portable device. The compressor group with electric motor is housed within the device body along with rechargeable batteries, eliminating the need for external equipment while maintaining sufficient compressed air generation capability for effective nasal irrigation
Solution Approach 2:
The device integrates multiple functions into one unit: the compressor generates compressed air, the battery provides power, the nebulization system delivers medicated liquid, and the collection chamber receives discharged matter. This multi-functional integration eliminates the need for separate external equipment while maintaining therapeutic effectiveness
2Ease of manufacture
If functional components are housed in a body without hermetic sealing, then the device structure is simpler, but cleaning and disinfection becomes difficult, posing infection risks
Solution Approach 1:
The patent employs hermetic sealing mechanisms including gaskets and seals between the body, cap, and collection chamber. These sealing elements create a closed, washable structure that protects internal components while allowing the entire device to be easily cleaned and disinfected without exposing sensitive internal parts to water or cleaning agents
Solution Approach 2:
The device is divided into separable components (body, cap, collection chamber) that can be disassembled for cleaning. The hermetic sealing between segments allows each part to be cleaned independently while maintaining protection of internal components during the cleaning process
3Device complexity
If the device lacks integrated power supply, then the device structure is simpler, but it requires external electric connections, reducing autonomy and portability
Solution Approach 1:
The device is equipped with rechargeable batteries that provide self-contained power supply, enabling autonomous operation without external electric connections. The batteries can be recharged by connecting the device to the electric network, but during use, the device operates independently, providing true portability and convenience for nasal irrigation anywhere

AI summary
The invention concerns a device for washing nasal cavities by a nebulised liquid, that comprises a main body (12), a tank for liquids (14) possibly subdivided into a nebulisation chamber (23) and a collection chamber (24) of the substances returning from the nasal cavities, and means of collection and nebulisation of the treatment liquid from said nebulisation chamber and delivery of the nebulised liquid towards the nasal cavities with the help of a flow of air under pressure generated by a compressor group. The main body (12) has a cavity and the compressor group (18) is housed in said cavity in communication, on one part, with the outside by means of an intake passage (21) and, on the other part, with said means of collecting and nebulisation of the treatment liquid by means of a delivery nozzle (21').
