Uroflowmetry Apparatus for Non-Invasive Prostate Diagnosis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current uroflowmetry procedures are inefficient for early detection of prostate pathology, particularly benign prostate hyperplasia (BPH) and prostate carcinoma, as they often require invasive methods and are not easily administered by general physicians, leading to delayed diagnosis.
Innovation Solution
A self-contained, electro-mechanical uroflowmetry apparatus that measures urine flow and provides graphical or electronic output, allowing for non-invasive, quick, and cost-effective urine flow analysis, enabling any medical professional to diagnose prostate-related issues by determining abnormal flow rates and patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If digital rectal examination (DRE) is used for prostate screening, then the procedure can be performed by general physicians, but it cannot assess the median lobe and has limited diagnostic value
Solution Approach 1:
The patent introduces an intermediary device (uroflowmetry apparatus with funnel and collection cup) that mediates between the patient and the diagnostic process. This intermediary enables indirect measurement of urine flow parameters that reflect prostate function, overcoming the limitations of direct physical examination while maintaining ease of administration by general physicians.
Solution Approach 2:
The patent replaces the mechanical manual examination (DRE) with an automated electronic measurement system that objectively quantifies urine flow parameters. This substitution transforms subjective physical examination into objective digital data collection, improving diagnostic accuracy without requiring specialized urological skills.
2Measurement precision
If uroflowmetry is implemented with comprehensive features, then diagnostic accuracy improves, but device complexity and cost increase
Solution Approach 1:
The patent segments the uroflowmetry apparatus into distinct functional modules: a disposable funnel for urine collection, a collection cup for measurement, a force sensor for weight detection, and an electronic display for results. This segmentation allows each component to be optimized independently and simplifies manufacturing and maintenance while maintaining overall diagnostic accuracy.
Solution Approach 2:
The patent employs disposable funnel and collection cup components that are inexpensive and single-use. This approach eliminates the need for complex cleaning and sterilization systems, reduces device complexity, and ensures hygiene without compromising measurement precision. The disposable nature also reduces long-term maintenance costs.
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
Facilitates early detection of prostate-related problems by providing accurate and reliable urine flow data, enabling timely intervention and reducing the need for invasive procedures, thus improving diagnostic efficiency and accessibility.
Implementation Method 1
The force sensor measures the weight of the collection cup and urine to determine urine flow volume
Data Source
AI summary
The present invention generally pertains to an apparatus and a method for uroflowmetry. Uroflowmetry can generally be defined as the collection and measurement of a patient's urination for the purpose of determining urine flow data that are necessary to analyze the patient's urination by comparing the patient's urine flow data to standardized urine flow data of healthy individuals. The present invention allows medical professionals to non-invasively diagnose a patient's urination by collecting, measuring and computing urine flow data to determine if any medical conditions and symptoms that affect urine flow are present. The within invention is designed and constructed in such a manner as to allow for the collection and measurement of urination to be done quickly, easily and at a reduced cost.
