Respiratory Mask with Segmented Air Chamber for Gas Exchange
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional respiratory masks suffer from poor gas exchange efficiency due to small pore diameters, leading to gas leakage and the risk of reinhalation of exhaust gases, which can contain bacteria, potentially causing infections.
Innovation Solution
A respiratory mask design featuring a main part, air chamber exchange part, insert, and clamping part that allows for separate or combined gas delivery to the nose and mouth, with a one-way exhaust assembly that uses pressure differences to manage gas exchange without additional power, reducing the risk of infection and gas leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If small pore diameters are used in traditional masks to avoid gas leakage, then gas leakage is reduced, but exhaust gas removal efficiency deteriorates remarkably
Solution Approach 1:
The mask is divided into separate functional components: a main body portion with exhaust holes for gas leakage prevention, and a detachable insert with additional exhaust holes for enhanced exhaust gas removal. This segmentation allows each component to optimize its function without compromising the other.
Solution Approach 2:
Different regions of the mask have different pore characteristics. The main body has small pores for preventing gas leakage, while the insert provides larger or additional exhaust pathways specifically for efficient exhaust gas removal, creating local quality variations to satisfy conflicting requirements.
2Productivity
If exhaust holes are added to improve exhaust gas removal, then exhaust gas removal efficiency is improved, but gas leakage increases
Solution Approach 1:
The exhaust function is segmented into two systems: small exhaust holes in the main body for controlled gas leakage prevention, and a detachable insert with additional exhaust capability for improved exhaust gas removal when needed.
Solution Approach 2:
The insert can be detached or attached based on operational needs, allowing the system to dynamically adjust its exhaust capacity. When the insert is attached, exhaust gas removal efficiency is maximized; when detached, gas leakage prevention is prioritized.
3Device complexity
If a single air chamber is used, then device complexity is reduced, but gas exchange efficiency deteriorates due to reinhalation of exhaust gases
Solution Approach 1:
The air chamber is segmented into a first air chamber for receiving fresh gas and a second air chamber for collecting exhaust gas. This segmentation prevents reinhalation by physically separating fresh and exhaust gas pathways, thereby improving gas exchange efficiency without excessive complexity.
4Ease of operation
If multiple components are integrated into a single unit, then ease of operation is improved, but adaptability deteriorates as users cannot customize gas delivery
Solution Approach 1:
The mask system is segmented into a main body and a detachable insert, allowing users to attach or detach the insert based on their specific needs. This provides adaptability for different gas delivery requirements while maintaining ease of operation through simple attachment and detachment.
Solution Approach 2:
The detachable insert serves multiple functions: it can be used for enhanced exhaust gas removal, customized gas delivery to different facial regions, or removed entirely for different usage scenarios. This multi-functionality provides adaptability without complicating the basic operation.

AI summary
The present invention discloses a respiratory mask to connect a user and a breathing tube for receiving a first gas and releasing a second gas, so as to provide an user's respiratory system to exchange gas. It comprises a main part, an air chamber exchange part, an insert and a clamping part. The main part provides a first, second, and third openings that are communicated each other. The first opening connects to the breathing tube to receive the first gas from the breathing tube. The air chamber exchange part provides an exhaust assembly to relieve pressure according to an internal air pressure of the air chamber exchange part. The insert connects to the user's nose so as to direct the first gas to the user or direct the second gas from the user to the air chamber exchange part. The clamping part connects to the user's mouth.
