Solution Overview
Problem
Current respiratory face mask assemblies require multiple types for different applications, leading to increased costs and storage challenges for healthcare facilities due to the need for various configurations and functionalities.
Innovation Solution
A modular mask assembly system with a mask body that includes a seal structure for patient engagement and a breathing circuit interface with a rotatable connector, allowing for interchangeable conduits with different functionalities, such as an entrainment valve assembly and a standard elbow, to accommodate various therapeutic gas delivery needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple different types of face mask assemblies are stocked for different applications, then the adaptability and versatility for various therapeutic needs is improved, but the storage space requirements and costs increase significantly
Solution Approach 1:
The mask assembly is designed with a universal interface that can accommodate multiple types of conduits (single limb and dual limb circuits) through a single connector structure. The connector includes a body with a first interface for the mask and a second interface for the conduit, allowing one mask assembly to perform multiple functions that previously required separate mask assemblies for different therapeutic applications
Solution Approach 2:
The system is divided into separable components: a reusable mask assembly with connector and interchangeable conduits. This segmentation allows the mask body to remain while only the conduit needs to be changed for different applications, reducing the need to store multiple complete mask assemblies and thereby reducing storage space requirements
2Adaptability or versatility
If multiple different types of face mask assemblies are maintained in inventory, then the ability to meet diverse therapeutic requirements is improved, but the costs associated with stocking and managing multiple assemblies increase
Solution Approach 1:
A single mask assembly with a universal connector design can interface with both single limb and dual limb conduits, eliminating the need to purchase and maintain separate mask assemblies for different circuit types. This universality reduces the overall quantity of equipment needed and associated costs while maintaining versatility for various therapeutic applications
Solution Approach 2:
The modular design allows the expensive mask body and connector to be retained and reused, while only the less expensive conduits are exchanged for different applications. This approach recovers the value of the mask assembly infrastructure and reduces long-term costs compared to replacing entire mask assemblies

AI summary
A mask assembly is provided for delivering gas to a patient that includes a mask body and a breathing circuit interface. The mask body includes an opening for reception of the gas and includes a seal structure for sealingly engaging with the face of the patient and surrounding at least the nose and mouth of the patient. The breathing circuit interface includes a first portion rotatably connected with the mask body and a second portion that is constructed and arranged to releasably connect with a conduit for delivering the gas to the patient through the opening.
