Automatic Analyzer Shared Diluted-Specimen Supply for Multiple Reaction Lines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic analyzers face an increase in size and complexity due to the number of diluted specimen lines, mechanisms for stirring, and cleaning, which complicates the device structure.
Innovation Solution
An automatic analyzer with a diluted specimen cell turntable and a diluted specimen dispensing unit that supplies diluted specimens from one line to multiple reaction lines, reducing the need for multiple specimen lines and associated mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple diluted specimen lines are provided for multiple reaction lines, then each reaction line can be supplied with diluted specimen independently, but the number of stirring mechanisms, specimen supply mechanisms, and cleaning mechanisms increases, causing the device size to increase and structure to become complicated
Solution Approach 1:
A single diluted specimen line is designed to serve multiple reaction lines through a shared diluted specimen supply mechanism. The diluted specimen cell turntable positions diluted specimen cells at different locations, and one diluted specimen supply probe can sequentially or simultaneously supply diluted specimens to multiple reaction lines, making the supply mechanism universal rather than dedicated to each line.
Solution Approach 2:
Multiple diluted specimen supply functions are merged into a single diluted specimen supply mechanism. Instead of having separate stirring mechanisms, specimen supply mechanisms, and cleaning mechanisms for each diluted specimen line, these functions are consolidated into shared mechanisms that serve multiple reaction lines through the single diluted specimen line.
2Reliability
If the number of diluted specimen lines increases to match the number of reaction lines, then specimen supply reliability improves, but the analyzer size increases due to additional mechanisms
Solution Approach 1:
The diluted specimen cell turntable and supply mechanism are designed with multi-functionality to serve multiple reaction lines. The turntable can position diluted specimen cells to supply multiple reaction lines sequentially or simultaneously, and the supply probe can service multiple lines, making the system reliable without requiring proportional increases in hardware for each reaction line.
Solution Approach 2:
The system transitions from a one-to-one correspondence between diluted specimen lines and reaction lines to a many-to-one relationship by utilizing the spatial dimension of the diluted specimen cell turntable. The turntable rotates to bring different diluted specimen cells into position, enabling a single supply mechanism to access multiple reaction lines through rotational positioning rather than requiring multiple fixed supply lines.

AI summary
An automatic analyzer (1) includes a diluted specimen cell turntable (3), a plurality of reaction lines (6A, 6B), and a diluted specimen dispensing unit (22). The diluted specimen cell turntable (3) has a plurality of diluted specimen cells (P3) that contains a diluted specimen. The plurality of reaction lines (6A, 6B) is supplied with the diluted specimen, in which the diluted specimen is reacted with a reagent. The diluted specimen dispensing unit (22) supplies the diluted specimen contained in the diluted specimen cell (P3) of the diluted specimen cell turntable (3) to the plurality of reaction lines (6A, 6B). The diluted specimen dispensing unit (22) supplies the diluted specimen from one diluted specimen line provided in the diluted specimen cell turntable (3) to the plurality of reaction lines (6A, 6B).
