Reagent Container Shield Plate for Spatter Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increased centrifugal force and high-speed rotation of reagent containers in automatic analysis apparatuses lead to reagent spattering, which can stain identification labels and cause reading failures, especially with larger capacity containers.
Innovation Solution
A reagent container design featuring a second opening with an attachable/detachable lid equipped with an air vent and shield plates to prevent spattering, where the air vent has an area equal to or greater than the first opening, and a wave motion preventing tube to manage reagent oscillation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the reagent container capacity is increased to reduce frequent replacement, then the productivity is improved, but the reagent spatters out during high-speed rotation due to increased centrifugal force and impact
Solution Approach 1:
A shield plate is introduced as an intermediary component between the reagent and the air vent. The shield plate intercepts the spattering reagent before it can reach the air vent and escape to the exterior, thus resolving the contradiction by allowing large capacity containers to rotate at high speed without reagent spattering
Solution Approach 2:
The shield plate is positioned in advance to counteract the spattering motion of the reagent. By placing the shield plate between the reagent bulk and the air vent opening, it preemptively blocks the harmful spattering trajectory before the reagent can reach the vent, preventing the contradiction from manifesting
2Loss of time
If the reagent container capacity is increased to avoid frequent replacement, then the loss of time is reduced, but the reliability deteriorates due to reagent spattering that stains identification labels
Solution Approach 1:
The shield plate serves as a protective intermediary that blocks reagent spatter from reaching the identification label and window areas. This allows the use of large capacity reagent containers without compromising label readability, thus maintaining reliability while reducing replacement frequency
Solution Approach 2:
The shield plate converts the harmful spattering motion into a beneficial containment effect. By redirecting the spatter away from critical areas (identification label and window), the shield plate transforms the problematic high-speed rotation into a safe operating condition for large capacity containers

AI summary
A reagent container used in an automatic analysis apparatus capable of preventing reagent in the reagent container from spattering out of the reagent container even when the reagent container with large capacity is rotated at a high speed and an automatic analysis apparatus using the reagent container are provided. A reagent container 12 for an automatic analysis apparatus has a first opening 27 used for sucking reagent and a second opening 28 used for the filling of the reagent. The second opening 28 is provided with an attachable/detachable lid 29. The lid 29 is provided with an air vent 33, a first shield plate 30 and a second shield plate 31 for preventing spattering of the reagent through the air vent 33 due to a wave motion of the reagent.
