One-Way Pipe Connector for Interior Medical Waste Gas Venting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for an efficient and adaptable pipe connector apparatus to safely vent medical waste gas from interior rooms without exterior building walls, as conventional venting systems are impractical in such scenarios.
Innovation Solution
A pipe-connector assembly system comprising a main pipe member, a valve housing with a one-way valve, and a riser, which connects a medical gas scavenger device to a drainpipe, allowing safe evacuation of waste gas into the building's wastewater collection system, preventing backflow and integrating with a plumbing trap under a washbasin.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a pipe vent is placed in an exterior building wall to exhaust waste gas, then the waste gas can be effectively vented outside, but this solution becomes impracticable when the medical device is located in an interior room with no exterior building walls
Solution Approach 1:
The patent introduces an intermediary venting system consisting of a connector apparatus that couples the exhaust hose to a drainpipe, which then connects to the building's wastewater collection system. This intermediary pathway allows waste gas to be discharged through the building's existing infrastructure rather than requiring direct exterior wall access, thereby enabling interior room installation while maintaining venting effectiveness.
2Adaptability or versatility
If a connector apparatus is installed under a washbasin to connect exhaust hose to drainpipe, then the system becomes adaptable to interior rooms, but the installation complexity and device complexity increase
Solution Approach 1:
The patent merges multiple functions into a single integrated connector apparatus that combines the exhaust hose coupling, valve housing with one-way valve, and drainpipe connection components. This consolidation reduces the number of separate parts and simplifies installation while maintaining the necessary adaptability for interior room applications.
Solution Approach 2:
The connector apparatus is designed with universal functionality to interface with standard exhaust hoses, integrate with existing drainpipe systems, and accommodate various installation locations under washbasins. The one-way valve component provides multi-functionality by preventing backflow while allowing forward flow, eliminating the need for separate backflow prevention devices.
3Reliability
If a one-way valve is installed in the valve housing to prevent backflow, then waste gas discharge safety is improved, but the device complexity increases
Solution Approach 1:
The one-way valve in the valve housing is designed as a self-regulating component that automatically prevents backflow without requiring external control mechanisms. The valve opens automatically when waste gas flows forward and closes automatically when backflow is detected, providing reliable backflow prevention while maintaining relatively simple device complexity through passive operation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively and safely evacuates medical waste gas from treatment rooms into the building's waste collection system, preventing backflow and ensuring safe disposal of gases like nitrous oxide and oxygen mixtures, while being easily installable and cost-effective.
Implementation Method 1
a valve residing within the valve housing and disposed between the proximal end and the distal end of the valve housing

AI summary
A connector apparatus featuring a main pipe with first and second opposed ends. Each has a corresponding male-threaded fastening section for mating with the complimentary female-threaded fastening section on a respective conventional pipe-locking ring or collar. A valve-housing for supporting a one-way flow valve assembly interiorly, and a riser mounted on and supported by the valve housing for ultimate connection to the output or exhaust nozzle of a medical scavenger device.
