Parallel Passage Automatic Fecal Occult Blood Detector
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current fecal occult blood detection methods are inefficient and prone to errors due to manual reading of test strip results, which delays the detection of early malignant tumors in the digestive tract and increases the workload in processing multiple samples.
Innovation Solution
An automatic fecal occult blood detector is designed with a parallel feed and discharging passage system, a push rod mechanism, a code scanner, and an image capturing device to automatically acquire and process information from identification tags and test strips, enabling simultaneous detection of multiple samples and reducing manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual reading of test strip color bands is used, then the detection process is simple and device complexity is low, but the workload is heavy, efficiency is low, and errors occur frequently
Solution Approach 1:
The system uses an image capturing device to automatically capture test strip results and a processing unit to automatically analyze the color bands, replacing manual reading with automated self-service detection that eliminates human error and increases throughput
Solution Approach 2:
The patent replaces the manual mechanical reading process with an automated optical system consisting of an image capturing device and digital processing unit that automatically analyzes test strip color bands, substituting human visual inspection with machine-based optical detection
2Productivity
If multiple sample kits are processed simultaneously, then the detection throughput increases, but the manual reading workload increases proportionally
Solution Approach 1:
The system maintains continuous detection operation by automatically processing multiple sample kits through the imaging and analysis system without interruption, eliminating the time loss associated with manual reading between samples and enabling uninterrupted high-throughput processing
3Productivity
If the detection system processes many samples, then the overall detection capacity increases, but the frequency of errors increases due to manual reading fatigue
Solution Approach 1:
The automated image capturing and processing system performs self-service detection without human intervention, eliminating reading errors caused by manual fatigue and maintaining consistent detection accuracy regardless of the number of samples processed
Solution Approach 2:
The processing unit automatically analyzes captured images and provides objective detection results, eliminating the subjective judgment errors that occur in manual reading and ensuring consistent accuracy across all samples

AI summary
The present invention discloses an automatic fecal occult blood detector for detecting a sample kit, comprising: a feed passage and a discharging passage which are provided in parallel and convey a sample kit separately; a transfer platform configured between the feed passage and the discharging passage; a push rod configured to push the sample kit on the feed passage onto the discharging passage through the transfer platform; and an image capturing device provided on one side of the discharging passage to acquire the color band information presented on a test strip. In the present invention, the parallel arrangement of the feed passage and the discharging passage shortens the whole length of the automatic detector, meeting the requirement that the color band information of the test strip is automatically acquired after the sample kit is left in the device a certain time.
