Ventilator Connector With Intervention Port
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medical ventilator systems require disassembly to perform interventional procedures, leading to interruptions in respiratory support and potential lung collapse, as they fail to maintain airway pressure during the introduction and removal of intervention devices.
Innovation Solution
A connector assembly with a housing having multiple ports, including a ventilator port, airway port, and intervention port, which allows for the introduction of intervention devices without disrupting the closed ventilator circuit, using a valve structure to maintain bidirectional fluid communication and preserve airway pressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the ventilator manifold/connector is disassembled to insert an intervention device, then the intervention device can be introduced into the artificial airway, but the closed ventilator circuit is interrupted and airway pressure is lost
Solution Approach 1:
The connector assembly is divided into multiple independent ports: a first port for the artificial airway, a second port for the ventilator circuit, and a third port for intervention devices. This segmentation allows each port to function independently, enabling intervention device access without disrupting the sealed connection between the airway and ventilator circuit.
Solution Approach 2:
The connector assembly serves multiple functions simultaneously: it maintains the sealed connection between the artificial airway and ventilator circuit while also providing access for various intervention devices through the third port. This multi-functionality eliminates the need to disassemble the connector for procedural access.
2Ease of operation
If the ventilator circuit is disconnected for intervention procedures, then the intervention can be performed, but respiratory support is interrupted and patient oxygen levels drop
Solution Approach 1:
The connector assembly enables continuous respiratory support by maintaining the sealed connection between the artificial airway and ventilator circuit throughout the intervention procedure. The third port provides access for intervention devices without requiring disconnection of the primary respiratory support pathway, ensuring uninterrupted oxygen delivery.
3Device complexity
If traditional manifold/connector designs are used, then the structure is simple, but intervention devices cannot be introduced without disassembly
Solution Approach 1:
The connector assembly incorporates a third port specifically designed to accommodate various intervention devices while maintaining the sealed connection between the artificial airway and ventilator circuit. This design provides versatility for different procedural needs without complicating the overall structure or requiring disassembly.

AI summary
A connector assembly for a medical ventilator including a housing having a plurality of ports including an intervention port disposed and structured to introduce an intervention device into said housing and a patient airway. The plurality of ports also include a ventilator port and an airway port respectively disposed and structured to connect a ventilator and an artificial airway in fluid communication with one another. A valve structure is movably and removably disposed within a valve port and is disposable between open and closed positions. The closed position comprising the intervention port sealed from fluid communication with the housing and a closed ventilator circuit defining fluid communication between the ventilator port and the airway port. The open orientation comprising the intervention port disposed in communicating relation with the airway port concurrent to fluid communication between the ventilator port and the airway port.
