Multi-port Oxygen Mask with Modifiable Diaphragms for Intubation Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional oxygen masks lack versatility, making it difficult to switch from nasal cannulas to oxygen masks during procedures, and they do not allow for easy access for various medical scopes, probes, or the connection of breathing-therapy devices, which limits oxygen delivery and monitoring options.
Innovation Solution
A multi-port, intubation-permitting oxygen mask with two modifiable diaphragms and multiple ports that can be converted for different procedures, allowing for adjustable access points and connections for breathing-therapy devices, enabling continuous oxygen delivery and monitoring of expired gases.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a standard oxygen mask is used to deliver high concentration oxygen, then oxygen delivery is improved, but access for medical scopes, probes, or tubes is blocked
Solution Approach 1:
The mask is divided into separate functional zones: a sealed mask body for oxygen delivery and detachable diaphragms with ports for procedural access. The diaphragms can be removed or modified independently to allow scope/probe insertion while maintaining oxygen sealing through the mask body itself.
Solution Approach 2:
The mask transitions from a static sealed design to a dynamic configuration where diaphragms can be removed, perforated, or modified during procedures. This allows the mask to adapt between providing complete sealing for oxygen delivery and creating access pathways for medical instruments as needed.
2Ease of operation
If conventional intubation masks are designed for specific entry points, then procedural access is improved, but versatility for different procedures is reduced
Solution Approach 1:
The mask body is designed as a universal platform that can accommodate multiple types of procedures through detachable diaphragms. The same mask body can be used with different diaphragm configurations for nasal intubation, oral intubation, scope insertions, or monitoring device attachments, making it suitable for diverse procedural needs.
Solution Approach 2:
Multiple diaphragm options and port configurations are prepared in advance and can be quickly exchanged during procedures. The mask comes with pre-configured options for different access needs, allowing rapid adaptation without requiring multiple different masks for different procedures.
3Ease of operation
If a nasal cannula is used for oxygen delivery, then patient comfort is improved, but oxygen concentration delivery is insufficient
Solution Approach 1:
The invention combines the comfort benefits of nasal cannula-style nasal diaphragms with the high oxygen concentration delivery capability of sealed mask bodies. The nasal diaphragm can be used alone for comfort or combined with the full mask body when higher oxygen concentrations are needed, merging the advantages of both approaches.
4Ease of manufacture
If the mask is designed with fixed structure, then manufacturing simplicity is improved, but adaptability for different procedures is reduced
Solution Approach 1:
The mask is manufactured as segmented components (mask body, diaphragms, ports) that can be produced using simple, standardized processes. Each component is relatively simple to manufacture, but their combination provides complex functionality and adaptability for various procedures.

AI summary
A versatile, multi-port, intubation-permitting oxygen mask is provided including two diaphragms (nasal and oral) each configured with a continuous, flexible, modifiable membrane from which an instrument-access port may be manually constructed, when and if needed. The novel oxygen mask preferably includes a multiple-inlet port having a standard oxygen tube connector and an interchangeable breathing-therapy device connector, a carbon dioxide sampling port, an exhaust port, and a nose clip. The mask can be worn as a standard oxygen mask during traditional oxygen therapy, yet quickly converted into an intubation mask. The clinician manually perforates the nasal and/or oral diaphragm to create a point and size of entry perfectly matched to the requirements for a variety of procedures that may be performed involving nasally or orally introduced scopes or probes—without disturbing the ongoing benefits of increased oxygen saturation and continuous monitoring of expired gases.
