Dual-Mode Urine Analyzer Using Dynamic Reagent Mixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional urine analyzers are limited to analyzing only urine samples and require separate analyzers for body fluids, leading to inefficiencies in medical settings where both types of samples need to be examined.
Innovation Solution
A urine analyzer capable of operating in both urine and body fluid measurement modes, using a specimen preparing section to mix samples with specific reagents and a detecting section to analyze red blood cells and bacteria in urine, and white blood cells and nucleated cells in body fluids, utilizing a single device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional urine analyzer is used, then urine samples can be analyzed accurately, but body fluid samples cannot be analyzed (requiring separate analyzers)
Solution Approach 1:
The analyzer is designed with multiple measurement modes (urine measurement mode and body fluid measurement mode) that can be switched via a mode setting unit. The same analyzer hardware processes both urine and body fluid samples by adjusting operational parameters, eliminating the need for separate dedicated analyzers for different sample types.
2Reliability
If separate analyzers are installed for urine and body fluid analysis, then each sample type can be analyzed with dedicated equipment, but the number of devices and examination rooms increases
Solution Approach 1:
A single analyzer performs both urine and body fluid analysis functions, allowing one examination room to handle multiple sample types. This consolidates equipment usage and improves productivity without compromising measurement accuracy through mode-specific optimization.
Solution Approach 2:
The analyzer dynamically adjusts its operational parameters based on the selected measurement mode. Different measurement conditions are applied for urine versus body fluid samples, allowing the system to optimize performance for each sample type while using the same physical hardware.
3Productivity
If a single analyzer handles multiple sample types, then device utilization improves, but measurement conditions must be adjusted for different samples
Solution Approach 1:
The system employs a mode setting unit that dynamically changes measurement conditions based on the selected mode (urine or body fluid). This automated parameter adjustment simplifies the management of different measurement conditions while maintaining high analyzer utilization across multiple sample types.
