Reagent Container Holder for Fixed Aspiration and Waste Openings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional reagent container sets experience dislocation of stock fluid and waste fluid bags during transport, making it difficult to insert aspiration and discharge tubes correctly due to relative movement of openings with the external box case.
Innovation Solution
A reagent container set with a container holding member that maintains the aspiration and discharge openings at predetermined positions within a box, using a container support to position reagent containers and a waste fluid container so that the openings remain fixed, and a notch on the box for waste fluid discharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the stock fluid bag and waste fluid bag are placed adjacent to each other in an external box case, then the structure is simple and easy to manufacture, but the openings of the bags are dislocated during transport making tube insertion difficult
Solution Approach 1:
The patent divides the container system into three separate components: a stock fluid container, a waste fluid container, and a container holding member. Each container is equipped with its own opening positioned at a predetermined location, eliminating the need for alignment with the external box case and preventing dislocation during transport.
Solution Approach 2:
The container holding member acts as an intermediary structure that holds both the stock fluid container and waste fluid container. It features holding holes positioned to receive and secure the openings of both containers, ensuring they remain in correct positions during transport and operation.
2Device complexity
If the openings of the stock fluid bag and waste fluid bag are positioned relative to the external box case, then the structure is simple, but the openings become dislocated during transport due to inclination
Solution Approach 1:
The patent separates the container positioning function from the external box case by introducing individual holding holes in each container and a container holding member. This segmentation ensures that container openings maintain their positions independently of the box case orientation during transport.
Solution Approach 2:
The container holding member is designed with holding holes at predetermined positions before transport occurs. This preliminary positioning arrangement ensures that when containers are placed in the holding member, their openings are pre-aligned correctly, preventing dislocation during subsequent transport and inclination.

AI summary
A reagent container set is disclosed which comprises: a first reagent container for accommodating a first reagent to be used in a sample analyzer, the top part of the first reagent container having a first aspiration opening for inserting a first reagent aspirating tube to aspirate the first reagent; a waste fluid container for accommodating the first reagent used in the sample analyzer as a waste fluid, the top of the waste fluid container having a discharge opening for inserting a waste fluid discharging tube to discharge the waste fluid into the waste fluid container; a box for accommodating the first reagent container and the waste fluid container; and a container holding member for holding the first reagent container and the waste fluid container so that the first aspiration opening and the discharge opening are disposed at predetermined positions, the container holding member being maintained at a predetermined position within the box.
