Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic vaporizer systems face challenges in providing reliable and efficient connectors between the gas controller and the breathing filter system, which can lead to issues with volatile anesthetic gas delivery and patient anesthesia, analgesia, and sedation.
Innovation Solution
A connector system comprising a conduit manifold with separate conduits and an interface plug with ribs and grooves, allowing for isolated fluid communication and preventing cross-contamination, enabling free rotational orientation and efficient delivery of volatile anesthetic gases.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional connectors are used between gas controller and breathing filter system, then the system can be assembled, but cross-contamination between separate gas conduits may occur and reliable isolated fluid communication cannot be ensured
Solution Approach 1:
The connector is divided into separate isolated openings (210-260) in the second portion, with each opening corresponding to a specific conduit (110-160). The ribs (270-276) create distinct grooves (280-285) that form separate compartments, ensuring that fluid communication between the gas controller ports and conduit manifolds occurs through isolated pathways. This segmentation prevents cross-contamination between different gas streams while maintaining reliable fluid communication for each conduit.
2Ease of operation
If the connector requires specific orientation for proper connection, then aligned openings ensure correct fluid communication, but the connector cannot be freely rotated and installation flexibility is reduced
Solution Approach 1:
The connector employs asymmetric features including ribs (270-276) positioned at specific angular locations around the circumference, creating corresponding grooves (280-285). These asymmetric elements provide mechanical guidance and alignment during insertion, ensuring that the isolated openings (210-260) correctly align with the gas controller ports regardless of the connector's rotational position. This allows the connector to be freely rotated during installation while maintaining precise fluid communication pathways.
3Device complexity
If multiple conduits are bundled together in a single connector, then space is efficiently utilized, but preventing cross-contamination between adjacent conduits becomes more difficult
Solution Approach 1:
The connector integrates multiple conduits (110-160) into a single device while maintaining complete isolation between them. Each conduit has its own dedicated isolated opening (210-260) in the second portion, and the ribs (270-276) create separate grooves (280-285) that form individual compartments. This segmentation allows efficient spatial utilization with all conduits bundled in one connector while preventing any cross-contamination between adjacent gas streams through the isolated communication pathways.
