Syringe Handling Device for Automated IV Preparation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automated devices for preparing intravenous medication face challenges in efficiently capping and uncapping syringe needles, managing various types of closed system transfer devices (CSTDs), and ensuring operational safety and flexibility during fluid transfer operations.
Innovation Solution
A device for handling syringes with a cap support and a mechanism for joint removal and insertion of the needle and cap, along with a system for using different types of CSTDs, featuring a cap support with a housing for dimensional interference and a projection for fixing CSTDs or caps, and sensors for verification, allowing for rotational and linear movements to enhance productivity and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional caps are used to close syringes, then the syringe can be effectively closed, but the cap must be removed before needle insertion which risks loss of medication and release of harmful substances
Solution Approach 1:
The patent combines the cap and CSTD into a single integrated unit that remains attached to the syringe throughout the medication preparation process. The CSTD is designed to fit over the needle hub and lock in place, eliminating the need to remove a separate cap before needle insertion, thus maintaining containment while simplifying operation.
Solution Approach 2:
The CSTD is pre-assembled and attached to the syringe before the medication preparation process begins. This preliminary action ensures that the containment system is already in place, preventing the need for later removal and reattachment operations that could compromise sterility or cause medication loss.
2Adaptability or versatility
If multiple types of CSTDs are used to accommodate different syringe types, then versatility is improved, but device complexity increases
Solution Approach 1:
The patent designs a universal support structure with a standardized interface that can accommodate multiple types of CSTDs. The support includes a recessed area and retention mechanism that can adapt to different CSTD geometries, allowing a single automated device to handle various syringe-CSTD combinations without requiring complex switching mechanisms.
Solution Approach 2:
The support structure is segmented into modular components, including a removable CSTD holder and adjustable retention elements. This segmentation allows the system to accommodate different CSTD types by simply changing or reconfiguring the holder component rather than redesigning the entire mechanism.
3Productivity
If the needle remains exposed during medication preparation, then fluid transfer operations are simplified, but the risk of accidental puncture and contamination increases
Solution Approach 1:
The CSTD acts as an intermediary protective barrier between the needle and the environment. It features a shield or cover that can be positioned to protect the needle during storage and transport, while allowing controlled access during active use. This intermediary structure maintains needle protection without impeding fluid transfer operations when needed.
