Urostomy Bag UTI Detection Using Integrated Urine Diagnostics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Urostomates are prone to urinary tract infections (UTIs), which are difficult to detect due to the incapacity to urinate on demand and the complexity of using additional devices, leading to increased infection risk and complications.
Innovation Solution
An integrated diagnostic device within a urostomy bag that detects UTIs by analyzing urine for leukocytes and nitrites, providing visual indicators for early detection and self-monitoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If an integrated diagnostic device is added to the urostomy bag, then UTI detection capability is improved, but device complexity increases
Solution Approach 1:
The diagnostic device is integrated directly into the urostomy bag pouch, merging the collection function and diagnostic function into a single unified device. This eliminates the need for separate collection bags and separate diagnostic testing, thereby improving UTI detection capability while avoiding the complexity increase that would result from using multiple separate devices
Solution Approach 2:
The urostomy bag is designed to perform multiple functions: waste collection, waste storage, and diagnostic testing for UTIs. The pouch serves as both the collection container and the testing chamber, allowing the same device to handle both collection and diagnosis without requiring additional specialized equipment
2Ease of operation
If traditional separate diagnostic devices are used, then detection accuracy is maintained, but ease of operation deteriorates
Solution Approach 1:
The system enables the user to perform diagnostic testing themselves by simply observing visual indicators on the pouch. The diagnostic device automatically detects UTIs through chemical reactions with urine components (leukocytes, nitrites) and provides immediate visual feedback, eliminating the need for users to manually operate complex diagnostic equipment or interpret complex results
3Measurement precision
If frequent healthcare visits are made for UTI detection, then early detection accuracy is improved, but loss of time increases
Solution Approach 1:
The diagnostic device enables continuous preliminary monitoring of UTI conditions directly at home through the urostomy bag. By providing immediate detection capabilities that work continuously in the background, the system detects infections at the earliest stages without requiring scheduled healthcare visits, thereby maintaining high early detection accuracy while eliminating time loss from travel and waiting

AI summary
An ostomy bag (1) has a flange (3) adjoining at least one pouch (2) wherein the pouch (2) has an integrated diagnostic device (4) for detection of urinary tract infection and an inlet (5) leading to a waste collection space (6) defined by two opposing surfaces of two walls (7) (8), the opposing surfaces configured to separate on the introduction of waste through the inlet (5).
