Pre-Filled Lock Syringe With Integrated Disinfecting Cap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medical practices require separate products for catheter flushing, disinfection, and locking, which are not efficiently integrated, leading to overlooked disinfection and increased complexity in clinical procedures.
Innovation Solution
A pre-filled syringe system is developed that integrates a disinfecting cap with the syringe, allowing for a comprehensive solution that includes a barrel, plunger, and a disinfecting cap, enhancing compliance with SASH procedures and maintaining a physical barrier against contamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate products are used for catheter flushing, disinfection, and locking, then each function can be performed with dedicated equipment, but the overall procedure becomes more complex and time-consuming
Solution Approach 1:
The patent combines a syringe containing lock solution with a disinfecting cap into a single integrated pre-filled syringe system. The syringe barrel contains both the lock solution and the disinfecting cap, allowing catheter locking and disinfection to be performed with one device instead of separate products, thereby reducing procedural complexity while maintaining functional effectiveness
Solution Approach 2:
The integrated syringe system performs multiple functions: the syringe delivers lock solution for catheter locking, while the attached disinfecting cap provides disinfection. This multi-functional design eliminates the need for separate flushing, disinfection, and locking procedures, streamlining the overall catheter care process
2Reliability
If a disinfecting cap is added to the syringe system, then catheter sterility is maintained and disinfection is enhanced, but the device structure becomes more complex
Solution Approach 1:
The disinfecting cap is nested within or attached to the syringe structure, with the cap housing containing the disinfecting solution and the cap being positioned over the syringe tip. This nested arrangement allows the disinfecting function to be integrated without significantly increasing overall device complexity, while effectively maintaining catheter sterility
Solution Approach 2:
The syringe system is segmented into distinct functional components: the syringe barrel for lock solution delivery, the plunger for solution administration, and the disinfecting cap for sterility maintenance. This segmentation allows each component to perform its specific function while remaining part of an integrated system, balancing structural organization with functional effectiveness
3Reliability
If multiple separate products are arranged bedside, then each product can be optimized for its specific function, but the setup time and procedural time increase
Solution Approach 1:
The syringe is pre-filled with lock solution and the disinfecting cap is pre-attached to the syringe before use. This preliminary preparation eliminates the need for clinicians to assemble separate products at the bedside, reducing setup time and procedural time while maintaining the functional optimization of each component
