IV Connection Port Support Device with Slit Arms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing support devices fail to securely and conveniently hold intravenous connection ports in a static position, making it difficult for medical professionals and patients to safely connect and disconnect IV lines without risking needle pricking.
Innovation Solution
A support device comprising a base with a support flange and a connection post featuring a slit with concavely arcuate arms and a fastener that secures the IV connection port, allowing for stable positioning on a stabilizing member or the body, facilitating secure and easy connection and minimizing the risk of accidental needle pricking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If existing support devices are used to hold intravenous connection ports, then the device structure is simple, but the connection port cannot be securely held in a static position and requires two hands for safe connection
Solution Approach 1:
The connection post is segmented into a slit with spaced arms that can independently move to grasp the connection port. This segmentation allows the port to be securely held in a static position while maintaining a relatively simple overall device structure.
Solution Approach 2:
The slit in the connection post is designed to be flexible rather than rigid, allowing the spaced arms to dynamically adjust and grasp the connection port. This dynamic feature enables secure single-handed connection while keeping the base structure simple.
2Object-affected harmful factors
If existing support devices are used, then the device is easy to manufacture, but the risk of accidental needle pricking cannot be minimized
Solution Approach 1:
The connection port is pre-secured in a static position by the flexible slit and spaced arms before the needle insertion process begins. This preliminary securing action minimizes the risk of accidental needle pricking while maintaining ease of manufacture.
Solution Approach 2:
The flexible slit with spaced arms acts as an intermediary between the rigid base and the connection port, providing secure holding that reduces needle pricking risk without significantly complicating the manufacturing process.
3Reliability
If a secure holding mechanism is implemented, then the connection port can be held in a static position, but the device complexity increases
Solution Approach 1:
The flexible slit with spaced arms provides reliable holding through dynamic adaptation to the connection port shape, rather than through complex rigid mechanical structures. This achieves high reliability with minimal increase in device complexity.
Solution Approach 2:
The material properties of the connection post are changed to provide flexibility in the slit region, enabling secure holding of the connection port without requiring additional complex structural elements.

AI summary
An intravenous line connection support device holds an intravenous connection port in a static position relative to a static structure or patient to facilitate connection to the port. The device includes a support flange coupled to and extending from a base. A connection post is coupled to and extends from the base. A slit extends into the connection post defining a pair of spaced arms. Opposite faces of the spaced arms include concavely arcuate portions defining a receiver within the slit configured for receiving a connection port of an intravenous line therein. A fastener has a head and a shaft. The shaft extends through the arms and across the slit. The shaft engages the arms such that movement of the shaft selectively urges the arms together and apart wherein the fastener is configured for securing the connection port within the receiver.
