Solution Overview
Problem
Current respiratory access manifolds for intubated patients lack the ability to facilitate multiple therapies simultaneously without applying undesirable pressure or torque to the endotracheal tube, which can lead to complications and increased risk of infection.
Innovation Solution
A respiratory triple swivel manifold with a base port, central body, and lateral ports that allow for rotatable and movable connections, forming a Y-shape configuration to reduce pressure and torque, and include a ramp to guide devices smoothly into the endotracheal tube without folding or twisting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple devices are coupled to a respiratory manifold, then multiple therapies can be performed simultaneously, but undesirable pressure and torque are applied to the endotracheal tube
Solution Approach 1:
The manifold incorporates rotatable arms that can dynamically adjust their position and orientation. This dynamic capability allows the manifold to accommodate multiple devices at various angles while the rotation mechanism absorbs and redistributes mechanical stresses, preventing excessive pressure and torque from being transmitted to the endotracheal tube.
Solution Approach 2:
The manifold is divided into separate functional components including a base port, multiple arms with lateral ports, and a proximal port. Each arm can be independently positioned and rotated, allowing selective access and minimizing the transmission of forces from one device to the endotracheal tube through structural segmentation.
2Reliability
If a common manifold is used to reduce infection risk, then a closed system is maintained, but multiple devices may still apply torque to the endotracheal tube
Solution Approach 1:
The rotatable arms provide a dynamic mechanism that allows devices to be coupled and uncoupled without compromising the closed system integrity. The rotation capability enables stress relief while maintaining the sealed connection to the endotracheal tube, thus preventing infection while reducing torque transmission.
Solution Approach 2:
The manifold acts as an intermediary device between multiple external devices and the endotracheal tube. The rotatable arms serve as a mechanical mediator that decouples the torque-generating devices from the sensitive endotracheal tube, allowing the closed system to be maintained while protecting the tube from harmful forces.
3Adaptability or versatility
If multiple ports are provided on the manifold, then multiple devices can be coupled, but the structure becomes more complex
Solution Approach 1:
The manifold employs universal, standardized port configurations that can accommodate various types of respiratory devices. The arms with lateral ports serve multiple functions including device coupling, rotation for stress relief, and maintaining closed system integrity, reducing the need for specialized components for each device type.
Solution Approach 2:
Multiple functional elements are merged into a single integrated manifold structure. The base port, arms with lateral ports, and proximal port are combined into one cohesive device that provides multiple access points while maintaining a relatively simple overall structure that avoids excessive complexity.

AI summary
A respiratory triple swivel manifold is provided which has a base port, which is coupled to a central body. The central body has two laterally-positioned arms, and each arm has a lateral port. Each base port and each lateral port has an inner sleeve which is movable relative to its port. The manifold also has a proximal port coupled to the central body, which may or may not have a rotatable inner sleeve. At least one of the arms and its respective lateral port is positioned at an angle in a range of greater than 90 degrees but less than 180 degrees relative to the central body. Desirably, the base port, the central body and its arms and their respective ports form a Y-shape. The proximal port may intersect the Y-shaped manifold. The base port includes a ramp to direct an object moved through one port into a passageway of the manifold and through the base port to an endotracheal tube without folding, twisting or bunching of any portion of the object within the manifold.
