Tissue Sample Container With Segmented Orientation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for transporting and processing tissue samples are prone to misidentification, cross-contamination, and damage due to manual handling, which can lead to loss of sample orientation and increased processing time, especially when multiple samples from different sites are handled together.
Innovation Solution
A tissue sample container with individually configured sections to maintain the orientation and identity of each sample, featuring a base with sample holding sections and a lid that securely seals the samples, allowing for automated processing and fixation while preventing sample rotation, and incorporating a fluid dispensing mechanism for fixative distribution without opening the container.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple tissue samples are placed in the same container for transport, then transport efficiency is improved, but sample identification and orientation are lost
Solution Approach 1:
The container is divided into multiple individually configured sample holding sections, each capable of maintaining the orientation and identity of a specific tissue sample. This segmentation allows multiple samples to be transported together while preserving their individual characteristics through dedicated compartments with unique geometries that prevent rotation and maintain spatial orientation.
2Ease of operation
If tissue samples are handled manually during processing, then flexibility in processing is improved, but misidentification and cross-contamination increase
Solution Approach 1:
The container maintains sample orientation and identity throughout transport and processing by incorporating fixed geometric configurations in each sample holding section. This preliminary establishment of proper sample positioning eliminates the need for manual re-orientation during processing, reducing handling steps and minimizing opportunities for misidentification and cross-contamination while maintaining processing flexibility.
3Reliability
If the container is opened during fixation to add fixative, then fixation effectiveness is improved, but sample exposure to contamination is increased
Solution Approach 1:
The container incorporates a sealed fixation mechanism where fixative can be introduced through a closed system. The fixative is delivered via a sealed port or automated injection system that maintains the closed-state of the container, allowing effective fixation to occur while eliminating the need to open the container and thereby preventing contamination exposure.
4Object-affected harmful factors
If samples are transported in a closed container, then contamination is prevented, but sample orientation may be lost
Solution Approach 1:
The closed container is segmented into multiple sample holding sections, each with a unique geometric configuration designed to maintain the specific orientation of its contained tissue sample. The closed-state of the container prevents contamination while the individualized sections with fixed geometries preserve sample orientation throughout transport, resolving the contradiction between sealed protection and orientation maintenance.

AI summary
A tissue sample container including a base having a plurality of sample holding sections, which are configured to receive a plurality of tissue samples in a given orientation and are demarcated by section walls; and a lid configured to sealingly engage the base. The sample holding sections are sized and shaped to correspond to a specific tissue sample size and shape such that the base in cooperation with the section walls, maintain the given orientation and identity of the tissue samples within respective sample holding sections.
