Convertible Patient Interface Connector for Multi-Conduit Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing patient interfaces require adapters or complete replacement when switching between different conduit connection types, leading to therapy interruptions and inconvenience due to incompatible gas sources.
Innovation Solution
A patient interface with an adaptable connector system that can convert between different conduit connection types, allowing seamless switching without the need for adapters by using a convertible connector that pivots, swivels, or rotates to align with various conduit ends.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a patient interface uses a fixed connector type, then the connection geometry is simple and reliable, but the interface cannot accommodate different conduit types without adapters or replacement
Solution Approach 1:
The patient interface incorporates a universal connector system that can accept multiple conduit connection types (e.g., 15mm, 22mm, and other standard sizes) through a single integrated design. The connector includes interchangeable or convertible elements that allow it to function with different conduit standards without requiring separate adapters or replacement of the entire mask assembly.
Solution Approach 2:
The connector system includes movable or adjustable components that can be reconfigured between different connection geometries. This dynamic capability allows the connector to adapt its shape, size, or configuration to match different conduit types, transforming from a static single-purpose connector to a dynamic multi-purpose interface.
2Adaptability or versatility
If an adapter is used to connect incompatible conduit types, then connection compatibility is achieved, but therapy is interrupted and convenience is reduced
Solution Approach 1:
The patient interface is pre-equipped with a convertible connector system that can accommodate multiple conduit types without requiring additional adapters. The connector is designed in advance with the capability to switch between different connection geometries, eliminating the need for preliminary adapter preparation or manual conversion steps when changing gas sources.
Solution Approach 2:
The invention extracts the adapter function from a separate component and integrates it directly into the patient interface connector. By building the multi-format capability directly into the mask connector, the separate adapter element is eliminated, allowing direct connection between different conduit types without removal or replacement steps.
3Adaptability or versatility
If the entire mask is replaced to switch gas sources, then connector compatibility is ensured, but convenience is significantly reduced and therapy interruption increases
Solution Approach 1:
The invention separates the connector function from the entire mask assembly, making the connector an independent, interchangeable component. This segmentation allows the connector to be replaced or reconfigured without removing or replacing the entire mask, enabling gas source changes while keeping the main mask structure in place.
Solution Approach 2:
The connector system includes movable or adjustable components that can be reconfigured between different connection geometries. This dynamic capability allows the connector to adapt its shape, size, or configuration to match different conduit types, transforming from a static single-purpose connector to a dynamic multi-purpose interface.

AI summary
A patient interface comprises an opening for receiving a flow of gas from a conduit and an adaptable connector system for connecting at least two different types of conduit with the opening. The adaptable connector is permanently mounted with the patient interface so it cannot be lost and is able to swing into alignment with the opening, thereby providing a different connection end to be compatible with a second or further type of conduit connection end.
