Nasal Ventilation Mask with Rotating Oral Hinge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ventilation masks are inadequate for emergency situations during surgery, particularly when rapid intubation is required, as they must be removed to access the mouth, disrupting oxygen supply and complicating procedures.
Innovation Solution
A nasal ventilation mask with attachment ports and a detachable oral mask, featuring a rotating elastomeric hinge and exhalation scoop, allowing for continuous oxygen delivery while enabling access to the mouth for intubation procedures, and incorporating sensors and scavenging systems for monitoring and gas management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a full face mask is used to provide oxygen support, then oxygen delivery is maintained, but access to the mouth for intubation is blocked
Solution Approach 1:
The mask is divided into two separate components: a nasal mask that covers only the nose and a separate oral mask that covers the mouth. This segmentation allows the nasal mask to remain in place for continuous oxygen delivery while the oral mask can be removed to provide access to the mouth for intubation procedures.
Solution Approach 2:
The oral mask is designed to be detachable and removable, allowing dynamic adjustment of the system. During emergency intubation, the oral mask can be quickly removed while the nasal mask remains in place, providing both continuous oxygen support and access to the airway.
2Duration of action of stationary object
If a full face mask is used, then oxygen support is continuous, but mask removal is required for intubation causing oxygen interruption
Solution Approach 1:
By separating the mask into nasal and oral components, the nasal mask can remain in place during intubation procedures. This eliminates the need to remove the entire mask, thereby maintaining continuous oxygen support and preventing oxygen interruption that would occur with a full face mask.
Solution Approach 2:
The nasal mask acts as an intermediary oxygen delivery device that can remain in place while the oral mask is removed for intubation. This intermediary approach ensures continuous oxygen delivery through the nasal route while allowing access to the mouth for airway management.
3Adaptability or versatility
If a nasal mask with attachment ports is used, then functional accessories can be integrated, but device complexity increases
Solution Approach 1:
The nasal mask is designed with universal attachment ports that can accommodate various functional accessories such as CO2 scavengers, sensors, and other monitoring devices. This multi-functionality allows a single base design to support multiple clinical needs without requiring completely different mask systems.
Solution Approach 2:
The attachment ports serve as intermediary connection points that link the nasal mask to various functional accessories. These standardized interfaces simplify the integration of additional components while maintaining a relatively simple base mask structure, balancing versatility with complexity management.
