Transfer Set Integral Access Port for Disinfection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current peritoneal dialysis transfer sets lack an integrated access port, making it difficult to introduce disinfecting light directly into the system, which increases the risk of infection and complicates the disinfection process, especially in home treatments.
Innovation Solution
The development of a multifunctional transfer set with an integral access port that allows for the introduction of elongate members, such as fiber optics, without disrupting fluid flow, enabling effective disinfection and reducing infection risks by facilitating the delivery of disinfecting light directly into the transfer set and catheter.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional peritoneal dialysis transfer sets are used without an integrated access port, then the device structure remains simple, but disinfection becomes difficult and infection risk increases
Solution Approach 1:
The transfer set hub is designed with a multi-functional access port that serves multiple purposes: it allows introduction of disinfecting light sources for sterilization, enables injection of medications, and permits extraction of sample fluids. This single integrated port replaces the need for multiple separate access points, reducing infection risk while maintaining reasonable structural complexity.
Solution Approach 2:
The access port is designed as a separate, modular component that can be integrated into the transfer set hub. This segmentation allows the disinfection and medication functions to be added without completely redesigning the entire transfer set, making the complexity increase manageable while achieving the reliability improvement.
2Productivity
If an integrated access port is added to the transfer set, then disinfection efficiency improves, but the device complexity increases
Solution Approach 1:
The access port enables multiple functions including light delivery for disinfection, medication injection, and sample extraction. By consolidating these functions into a single integrated port rather than requiring separate access points, the design achieves improved disinfection efficiency without proportionally increasing overall device complexity.
3Ease of operation
If multiple separate devices are used for disinfection and medication administration, then device complexity remains low, but the number of connection steps increases and infection risk rises
Solution Approach 1:
The access port combines multiple functions (disinfection light delivery, medication injection, sample extraction) into a single integrated access point on the transfer set hub. This merging eliminates the need for multiple separate connection steps and devices, reducing both the complexity of the overall system and the infection risk associated with repeated connections.

AI summary
A multifunctional transfer set having an access port is disclosed. The multifunctional transfer set facilitates the introduction of elongate members insertably/retractably and allows fluid flow therethrough without requiring detachment during use. The multifunctional transfer set has a transfer set body assembly connected to a Y-adapter with an access port and a longitudinal portion. A longitudinal axis extends through the transfer set body assembly and longitudinal portion of the Y-adapter and not through the access port. An extension sub-assembly is connected to the access port, the extension sub-assembly having branch tubing, a flow-control device, and a coupling assembly allows fluid flow therethrough into and out of the transfer set body assembly if the flow-control device is open and prevents fluid from flowing therethrough if the flow-control device is closed. An existing transfer set without intervening side access may be converted into a multifunctional transfer set with a shorter longitudinal length.
