Sterile Connection Buckle With Unlocking Hole for Misconnection Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sterile connection technologies face issues with misconnections, leading to product waste and increased costs due to the non-removable nature of coupling devices, which results in structural damage and reduced service life when misconnections occur.
Innovation Solution
The introduction of a sterile connection member with a buckle connection mechanism and an unlocking hole allows for amicable disengagement of misconnected components without damaging the structure, utilizing hooks and snap plates for secure connections and a film puller for easy removal, enabling the release of the buckle connection through an unlocking member.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a non-removable buckle connection is used to ensure secure connection, then connection reliability is improved, but misconnection damage increases and service life decreases
Solution Approach 1:
The buckle connection structure is designed to be dynamically changeable between locked and unlocked states. The unlocking member can transform the rigid buckle connection into a separable one, allowing the connection to adapt between secure locked state during operation and removable state for correction of misconnections, thereby extending service life while maintaining reliability.
2Stability of the object's composition
If a rigid buckle connection is used to prevent disengagement, then connection stability is improved, but misconnection correction becomes difficult and product waste increases
Solution Approach 1:
The unlocking member is extracted as a separate functional component that can be inserted through the unlocking hole to release the buckle connection. This extraction mechanism allows the stable connection to be intentionally opened when misconnection is detected, enabling correction without damaging the connection members and reducing product waste.
3Duration of action of stationary object
If an unlocking mechanism is added to enable removable connection, then service life is improved, but device complexity increases
Solution Approach 1:
The unlocking mechanism is segmented into distinct functional parts: the unlocking hole as a passage, the unlocking member as a tool, and the buckle connection as the target structure. This segmentation allows each component to perform its specific function with simple geometry, avoiding the need for complex integrated mechanisms while still achieving removable connection capability.
4Ease of manufacture
If a simple snap connection is used to reduce complexity, then ease of manufacture is improved, but connection reliability decreases
Solution Approach 1:
The invention merges two connection functions into one structure: the buckle connection provides both the secure locking function and the controlled removability function. By combining these functions into the hook-and-slot structure with unlocking hole, the design achieves reliable connection without requiring separate complex locking mechanisms, maintaining manufacturing simplicity while improving reliability.

AI summary
Disclosed are a sterile connection member and a sterile connection apparatus. The sterile connection member includes a main body. A first surface of the main body is connected to an external pipeline. A fluid channel is arranged inside the main body. The fluid channel penetrates from the first surface to a second surface of the main body. The second surface includes at least one first hook and/or at least one second hook. The first hook is matched with a second hook of the main body of another sterile connection member to form a buckle connection, and/or the second hook is matched with a first hook of the main body of another sterile connection member to form a buckle connection. The sterile connection member further includes an unlocking hole formed in the main body and communicating with the buckle connection.
