UTI Indicator Substrate for Catheter Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for diagnosing catheter-associated urinary tract infections (CAUTIs) are labor-intensive, time-consuming, and often result in delayed detection and treatment, leading to significant morbidity, mortality, and financial costs due to the inability to promptly identify infections in patients with urinary catheters.
Innovation Solution
A urinary tract infection (UTI)-monitoring system that includes a catheter, collection tubing, and collection bag portions with integrated UTI indicator substrates that detect and signal the presence of markers such as leukocyte esterase and nitrites in urine, allowing for early detection and timely intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If urine dipsticks are used for UTI detection, then UTI markers can be detected, but the process becomes labor-intensive and time-consuming for nursing staff
Solution Approach 1:
The monitoring system enables automatic detection and notification of UTI markers in urine without requiring nursing staff to manually perform dipstick tests. The system self-monitors urine samples continuously and automatically alerts healthcare providers when UTI markers are detected, eliminating the labor-intensive manual testing process while maintaining detection capability.
Solution Approach 2:
The patent replaces the manual mechanical dipstick testing process with an automated electronic monitoring system that uses sensors and digital signal processing to detect UTI markers. This substitution eliminates the need for nursing staff to physically handle and interpret dipsticks, reducing workload while preserving diagnostic accuracy.
2Measurement precision
If manual urine sampling and dipstick testing are performed, then UTI can be detected, but significant time lapse occurs before diagnosis and treatment initiation
Solution Approach 1:
The monitoring system provides continuous monitoring of urine for UTI markers rather than periodic manual testing. Urine flows continuously through the monitoring device, enabling real-time detection of UTI markers as they appear, eliminating the time delay between infection onset and diagnosis that occurs with intermittent manual sampling.
Solution Approach 2:
The system performs preliminary detection of UTI markers in real-time before clinical symptoms manifest or before manual testing would be initiated. By continuously monitoring urine composition and detecting marker changes immediately, the system enables early intervention before the condition progresses to require urgent treatment.
3Reliability
If current manual monitoring procedures are used, then UTI can be identified, but the cost in dollars and human life is substantial
Solution Approach 1:
The monitoring system provides continuous feedback to healthcare providers about UTI marker levels in real-time, enabling immediate clinical decision-making. This feedback loop allows for timely adjustment of treatment protocols and prevents progression to severe sepsis, thereby reducing mortality and healthcare costs while maintaining reliable UTI identification.
