Closed IV Line Draw System with Integrated Adapter
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current blood collection methods using peripheral intravascular catheters (PIVCs) are cumbersome and prone to contamination due to the need for multiple device connections and disconnections, increasing the risk of exposure to blood and contamination of the catheter system.
Innovation Solution
A closed IV line draw system with an integrated adapter and syringe that allows for flushing and discard sample collection without disconnecting from the PIVC, followed by the insertion of a vacuum-sealed blood tube to collect blood samples, maintaining a closed system throughout the process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple devices are connected and disconnected from the PIVC during blood collection, then various blood collection functions (flushing, discard sample, blood samples) can be performed, but the process becomes cumbersome and increases the risk of contamination and blood exposure
Solution Approach 1:
The patent combines multiple devices (adapter, syringe, blood collection tubes) into a single integrated closed system that attaches to the PIVC once. The adapter serves as a hub that accommodates the syringe for flushing and discard sample collection, then allows blood collection tubes to be attached without disconnecting from the PIVC, thereby merging multiple functions into one continuous connection.
Solution Approach 2:
The adapter is designed as a universal interface that can accommodate different devices for different blood collection functions. It provides a common connection point that works with syringes for flushing, discard sample collection, and vacuum blood collection tubes, allowing one device to perform multiple functions.
2Adaptability or versatility
If multiple devices are connected and disconnected from the PIVC during blood collection, then various blood collection functions can be performed, but the risk of contamination and blood exposure increases
Solution Approach 1:
By merging multiple blood collection functions into a single integrated closed system that remains attached to the PIVC throughout the process, the patent eliminates the repeated connection and disconnection steps that create contamination risks. The system maintains a continuous closed barrier between the blood and the external environment.
Solution Approach 2:
The adapter acts as an intermediary device between the PIVC and the various blood collection instruments. It provides a sealed interface that allows the syringe and blood collection tubes to access the PIVC through the adapter without directly exposing the PIVC connection point to the external environment, thereby reducing contamination risk.
3Adaptability or versatility
If multiple devices are connected and disconnected from the PIVC during blood collection, then various blood collection functions can be performed, but the time required for the procedure increases
Solution Approach 1:
The patent merges multiple blood collection functions into a single continuous procedure using an integrated closed system. The adapter remains attached to the PIVC throughout flushing, discard sample collection, and blood sample collection, eliminating the time lost to repeated connection and disconnection of devices.
Solution Approach 2:
The closed system maintains continuous connection to the PIVC throughout the entire blood collection process. The adapter provides an uninterrupted access point that allows sequential performance of flushing, discard sample collection, and blood sample collection without breaking the sterile barrier or requiring re-attachment, thereby maintaining continuous useful action.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Simplifies the blood collection process by requiring only a single connection to the PIVC, reducing the risk of contamination and exposure to blood, while maintaining a closed system for efficient sample collection.
Implementation Method 1
one or more vacuum sealed blood tubes are commonly attached to the PIVC. While attached, the vacuum present in the tubes causes blood to flow from the PIVC and into the tubes

AI summary
The present application extends to a closed IV line draw system which may be used with a PIVC or another vascular access device to collect blood samples. The closed IV line draw system consists of various integrated components that allow the system to remain closed during the blood collection process. In this way, the closed IV line draw system simplifies the blood collection process and reduces the risk of contamination to the PIVC or other vascular access device.
