Priming Cap Air Venting via Hydrophobic Filter
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional medical connector priming systems are inefficient and risk-prone, as they often require additional solutions like saline to prevent air from entering IV lines, leading to potential bloodstream infections and increased priming time due to the difficulty in venting trapped air without exposing the system to contamination.
Innovation Solution
A priming cap with a conduit housing, resilient member, and valve activation mechanism that securely attaches to medical connectors, allowing for the venting of trapped air without fluid leakage, using a plug with a hydrophobic filter to prevent liquid passage and facilitate air expulsion, thereby simplifying the priming process and reducing infection risk.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional priming systems use additional solutions like saline to prevent air from entering IV lines, then fluid pathway establishment is achieved, but the risk of bloodstream infection increases and priming time is extended
Solution Approach 1:
The patent extracts the harmful element (air) from the system by providing a dedicated venting pathway through the priming cap. The vent port allows trapped air to escape during priming without requiring additional fluids like saline, thereby reducing infection risk while maintaining efficient priming time.
Solution Approach 2:
The hydrophobic filter acts as an intermediary component that selectively allows air to pass through while blocking liquid. This mediator enables air venting during priming without allowing contaminated fluid to escape or enter the system, thus reducing infection risk without extending priming time.
2Reliability
If conventional systems require cleaning and sanitization of connectors before cap attachment, then sterility is maintained, but the priming process becomes more complex and time-consuming
Solution Approach 1:
The priming cap is designed to be attached to the connector before the priming process begins, serving as a pre-established barrier that maintains sterility without requiring separate cleaning and sanitization steps. The cap's integrated design simplifies the overall process while preserving sterility.
Solution Approach 2:
The priming cap serves multiple functions simultaneously: it acts as a sterile barrier, provides an air venting pathway, and secures to the connector without requiring additional manipulation steps. This multi-functionality reduces process complexity while maintaining sterility.
3Reliability
If the priming cap uses a resilient member to secure to the connector, then attachment reliability is improved, but the structure becomes more complex
Solution Approach 1:
The resilient member provides dynamic attachment capability, allowing the priming cap to securely engage with the connector through elastic deformation. This dynamic mechanism ensures reliable attachment while using a simple, flexible component rather than a complex mechanical fastening system.
Solution Approach 2:
The resilient member is implemented as a flexible elastic band that surrounds the connector and provides securing force through its elastic properties. This flexible component achieves reliable attachment without requiring complex rigid structures or multiple fastening elements.

Function Achieved in This Case
The priming cap effectively vents air from medical connectors without introducing additional fluids, reducing the risk of infection and streamlining the priming process, ensuring efficient and safe fluid pathway establishment.
Implementation Method 1
a plug with a hydrophobic filter to prevent liquid passage and facilitate air expulsion
Implementation Method 2
The resilient member can include a retaining feature extending laterally across a portion of the resilient member. The retaining feature can secure the priming cap to a portion of the medical connector.

AI summary
A priming cap includes a conduit housing and a resilient member. The conduit housing further includes an upper housing, a lower housing coupled to the upper housing, a fluid passageway extending through the upper housing and the lower housing; and a plug positioned within the upper housing. The conduit housing can define a valve activation member configured to open and close a medical connector. The resilient member can include a retaining feature to secure the priming cap to the medical connector.
