AI Technical Summary

Technical Problem

Current Foley catheters lack the ability to reliably and early detect catheter-related urinary tract infections (CUTIs) due to passive antimicrobial coatings that lose effectiveness over time, single-parameter monitoring systems leading to false positives/negatives, and uncontrolled local antimicrobial agent release posing safety risks.

Method used

An integrated smart Foley catheter system that measures multiple urine biochemical parameters (pH, nitrite, leukocyte esterase, ammonia, and enzymes) to generate a time-dependent infection risk score, alerts clinicians of exceeding thresholds, and allows physician-approved, micro-valve controlled local antimicrobial release with dose and safety limits.

Benefits of technology

Enables early and reliable infection detection, reduces false alarms, ensures safe and targeted treatment, minimizing systemic antibiotic use and catheter changes, and simplifies clinical workflows.

Abstract

The invention encompasses an intelligent Foley catheter system for the early diagnosis and treatment of catheter-related urinary tract infections. It includes a sensor module integrated into the body of a Foley catheter that detects multiple biochemical parameters in urine, a risk analysis algorithm that generates an infection risk score from the detected data, and a micro-reservoir and micro-valve that, based on the risk score generated by this algorithm, delivers a controlled local antimicrobial agent with physician approval.
