Histological Sample Treatment Device Code Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current treatment devices for histological or cytological samples face challenges in accurately replacing or replenishing treatment agents, often leading to incorrect substitutions due to the large number of containers, which can result in samples being treated with the wrong agents and subsequently becoming unavailable for further investigation.
Innovation Solution
A treatment device equipped with a detection apparatus to read codes on treatment agent packages or containers, an evaluation apparatus to determine the correct container for replenishment or replacement, and an indicating apparatus to inform the user which container needs attention, thereby reducing the risk of incorrect substitutions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple containers for different treatment agents are used, then the treatment capability is improved, but the risk of incorrect replacement or replenishment increases
Solution Approach 1:
The system uses detection apparatus to read codes from treatment agent packages and provides feedback through an indicating apparatus to guide users to the correct container. This closed-loop feedback mechanism ensures that even with multiple containers, the correct agent is always identified and replaced, eliminating the risk of incorrect substitution while maintaining full treatment capability.
Solution Approach 2:
A code identification system serves as an intermediary between the treatment agent packages and the containers. The code on each package acts as a mediator that links the specific treatment agent to its designated container through detection and evaluation apparatus, preventing direct confusion between similar-looking containers while preserving the multi-container treatment capability.
2Device complexity
If manual replacement of treatment agents is performed, then the device complexity is reduced, but the productivity decreases
Solution Approach 1:
The system performs preliminary actions by automatically detecting which container needs replenishment and identifying the correct treatment agent before the user performs the replacement. The detection apparatus reads codes and the evaluation apparatus determines the correct container in advance, so the user only needs to perform the simple physical replacement action, combining automation benefits with minimal user intervention.
Solution Approach 2:
The system provides self-service functionality where the detection and evaluation apparatus automatically identify and guide the replacement process without requiring complex user judgment. The indicating apparatus directs the user to the correct container, making the replacement process as simple as following visual guidance while maintaining high productivity through automated intelligence.
3Measurement precision
If codes are added to treatment agent packages, then the measurement precision of agent identification is improved, but the device complexity increases
Solution Approach 1:
The system replaces complex mechanical identification methods with optical or electromagnetic code reading. Instead of using complex mechanical recognition systems, simple barcode or data matrix codes are read by detection apparatus, achieving high identification precision with minimal added complexity. The code itself is a simple graphical element that can be read by standard scanning technology.
Solution Approach 2:
The system changes the identification parameter from physical characteristics of containers to coded information. By encoding container identity in readable codes rather than relying on physical differentiation, the system achieves precise identification with simple detection apparatus. The code parameter transforms a potentially complex physical recognition problem into a simple optical reading task.

AI summary
A treatment device (1) for treating histological or cytological samples has a plurality of containers (6) for different treatment agents and a detection apparatus (2) for detecting a code which unequivocally identifies a type of a treatment agent or a type of a group of treatment agents from a package or replacement container of a treatment agent or group of treatment agents. The device furthermore has an evaluation apparatus (18) that, based on a detected code, ascertains which of the containers is or are to be replenished or replaced, and an indicating apparatus (4) which communicates to a user the ascertained container (6) or containers (6) that is or are to be replenished or replaced. The indicating apparatus may include a display (5) presenting a schematic image of the plurality of containers (6) with image(s) of each ascertained container being marked, and/or a light source (15) that illuminates each ascertained container.
