Integrated Cleaning Device for IV Connectors and Catheter Hubs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for cleaning and disinfecting needle-free intravenous connectors and vascular access catheter hubs are inconsistent and ineffective, leading to increased catheter-related bloodstream infections due to contamination, resulting in significant healthcare costs and mortality rates.
Innovation Solution
An integrated cleaning and disinfecting device made of non-particulating, compressible absorbent plastic with a disinfectant agent, featuring a blind hole for engaging IV connector threads and a male-luer slip for catheter hubs, allowing simultaneous cleaning and disinfection of both by rotating and squeezing the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If 70% isopropyl alcohol pads are used for swabbing methods, then the disinfection process is simple and quick, but the cleaning consistency and effectiveness deteriorate due to practitioners missing areas or failing to clean threaded areas effectively
Solution Approach 1:
The cleaning device is segmented into distinct functional zones: a blind hole for engaging IV connector threads and a male-luer slip for catheter hub engagement. Each segment targets specific surfaces (threads, septum, hub interior) to ensure comprehensive coverage without missing areas, resolving the inconsistency problem while maintaining ease of use through intuitive design
Solution Approach 2:
The absorbent material impregnated with disinfectant acts as an intermediary between the practitioner and the surfaces being cleaned. This intermediary ensures consistent disinfectant application to all contacted surfaces including threaded areas, eliminating the variability introduced by manual swabbing technique while keeping the operation simple
2Reliability
If separate cleaning procedures are used for IV connectors and catheter hubs, then each component can be addressed with specific attention, but the time and complexity of the cleaning process increase
Solution Approach 1:
The device merges multiple cleaning functions into a single integrated tool. The blind hole cleans IV connector threads and septum, while the male-luer slip cleans catheter hub interior and exterior threads. This consolidation allows practitioners to clean both components in one continuous action, reducing time while maintaining effectiveness through dedicated cleaning zones
Solution Approach 2:
The cleaning device is designed with universal applicability to handle both IV connectors and catheter hubs with a single tool. The multi-functional design incorporates features (blind hole for connectors, male-luer slip for hubs) that enable effective cleaning of different components without requiring separate specialized tools, thus saving time while ensuring reliable cleaning of each component type
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
The device ensures thorough disinfection of both the septum and threads of IV connectors and the inner and outer threads of catheter hubs, reducing the risk of contamination and infections, thereby lowering healthcare costs and mortality rates.
Implementation Method 1
a single piece of non-particulating, absorbent plastic which stores a disinfectant agent in its pores
Implementation Method 2
compressible absorbent plastic with a disinfectant agent... optionally squeezing the first end, and rotating back and forth

AI summary
A single piece device enables medical clinicians to clean and disinfect both an injection port (needleless I.V. connector) and a vascular access catheter hub. The device has a body with a first end having a blind hole with a wall adapted to be engageable with the threads on the housing of an IV connector and a bottom surface adapted to engage the top surface of the IV connector. The device body has a second end defining a male-luer slip extending out of a recess. The male-luer slip is adapted to extend into a standard vascular access catheter hub such that it engages the inner walls of the catheter hub, and the recess is adapted to receive and be engageable with the outside thread element of the catheter hub.
