Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing test devices can only test single physiological indexes at a time, making it inconvenient for users to conduct comprehensive health assessments at home, which requires multiple biochemical index testing, and this limits their ability to avoid hospital or clinic visits, reduce waiting times, and lower testing expenses.
Innovation Solution
A device comprising a test strip with specific binding substances and an instrument body for analyzing multiple biochemical indexes, allowing users to test multiple indexes simultaneously by using test paper with sample, marker, and reaction zones, along with quality control lines, and an instrument for fluorescent or colloidal gold marker detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single test device tests one physiological index at a time, then the device structure remains simple, but the user cannot conduct comprehensive health assessment and must visit hospitals multiple times
Solution Approach 1:
The patent combines multiple test lines for different physiological indexes (urine protein, blood glucose, urine ketone, etc.) into a single integrated test strip. The test strip includes a sample adding zone, marker zone, and reaction zone with multiple test lines, allowing simultaneous detection of multiple biochemical substances in one test, thus resolving the contradiction between versatility and complexity
Solution Approach 2:
The test device is designed with universal functionality to detect multiple physiological indexes through a single test strip. The instrument body can analyze various biochemical substances (urine protein, blood glucose, urine ketone, urine nitrite, urine leukocyte, urine bilirubin, urine urobilinogen) using the same device structure, making the device multi-functional and eliminating the need for separate test devices for each index
2Ease of operation
If users go to hospital or clinic for comprehensive health examination, then accurate health assessment is obtained, but appointment and queuing troubles occur with high cost and long waiting time
Solution Approach 1:
The test device enables users to perform self-testing at home without requiring hospital or clinic visits. The test strip and instrument body allow users to independently complete comprehensive health examinations in their own environment, eliminating appointment scheduling, queuing, and waiting time, thus significantly improving ease of operation and reducing time loss
3Measurement precision
If multiple separate test devices are used to test different physiological indexes, then each index can be tested accurately, but the user experience becomes complicated and time-consuming
Solution Approach 1:
The patent merges multiple separate test devices into one integrated device. The test strip contains multiple test lines for different physiological indexes, and the instrument body can simultaneously analyze all indices through a single operation, reducing the number of devices from multiple separate units to one unified system while maintaining measurement precision for each index

Implementation Method 1
the test sample containing at least one biochemical substance to be tested permeates the marker zone under the chromatographic action of the test paper
Implementation Method 2
specific binding substances a which are marked by markers and can specifically bind to biochemical substances to be tested
Implementation Method 3
the content of the marker on the test line is tested and analyzed by the instrument body, to obtain concentration data of the biochemical substance to be tested
Implementation Method 4
The marker may be a fluorescent marker or colloidal gold or other types of markers
