Automatic Analyzer Mixer Unit for Consistent Detergent Concentration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing automatic analyzing apparatuses face issues with inconsistent detergent concentrations in washing liquids, leading to poor washing capabilities and potential degradation of analysis data due to either reduced or elevated detergent levels in the reaction containers.
Innovation Solution
The apparatus incorporates a mixer unit that strongly mixes a diluent with a concentrated detergent liquid to create a washing liquid with a constant detergent concentration, ensuring consistent washing performance and preventing detergent residue in reaction containers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If concentrated liquid and diluent are fed through different flow paths to join together in a channel, then the washing liquid is prepared for use, but the detergent component concentration becomes inconsistent leading to poor washing capability or residue in reaction containers
Solution Approach 1:
The flow path is divided into separate channels: a first flow path for the concentrated liquid and a second flow path for the diluent. These segmented flow paths prevent premature mixing and allow precise control of each component's delivery, ensuring consistent detergent concentration when the liquids join in the washing liquid storage container.
Solution Approach 2:
The washing liquid storage container acts as an intermediary chamber where the concentrated liquid and diluent are combined in controlled proportions. This intermediary space ensures thorough mixing and uniform distribution of the detergent component throughout the washing liquid before it is dispensed for washing operations.
2Reliability
If the washing liquid has reduced detergent component concentration, then the reaction container may not be washed properly, but if the concentration is increased, then detergent residue remains in the reaction container affecting analysis data
Solution Approach 1:
The system precisely controls the concentration parameter of the detergent component in the washing liquid by regulating the flow rates and mixing ratios of concentrated liquid and diluent through separate flow paths. This ensures the washing liquid maintains an optimal detergent concentration that effectively cleans reaction containers without leaving harmful residues that would affect analysis data.

AI summary
According to one embodiment, an automatic analyzing apparatus includes a feeder and a mixer unit. The feeder is configured to feed a first liquid and a second liquid. The mixer unit includes an inflow part, an internal space, and an outflow part. The mixer unit is configured so that the first liquid and the second liquid fed from the feeder enter through the inflow part, the first liquid and the second liquid entering through the inflow part flow inside the internal space, and the first liquid and the second liquid flowing inside the internal space exit through the outflow part according to an inflow entering through the inflow part.
