Networked Label Printer for Anatomical Pathology Sample Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Anatomical Pathology (AP) laboratories face inefficiencies in sample tracking and information management during the tissue staining process, leading to potential mix-ups and errors due to the lack of a comprehensive information tracking solution across the entire process.
Innovation Solution
Implementing a networked label printer system that accesses patient data from the hospital's Laboratory Information System (LIS), prints labels with test protocol information, and coordinates tissue sample information through machine-readable identifiers, ensuring accurate tracking and labeling of slides throughout the staining process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If batch-based manual tissue staining processes are used, then economy of scale is achieved through simultaneous processing of multiple samples, but sample tracking accuracy deteriorates leading to potential mix-ups and errors
Solution Approach 1:
The patent divides the batch processing workflow into individually trackable units by assigning unique barcodes to each tissue cassette and slide. This segmentation allows the system to maintain batch processing efficiency while tracking each sample's journey through the workflow independently, preventing mix-ups even when multiple samples are processed simultaneously.
Solution Approach 2:
The system implements feedback mechanisms through barcode scanning at each workflow stage (cassette accessioning, slide labeling, staining processing). Each scan provides real-time status updates to the LIS, confirming sample identity and location. This feedback loop ensures that any tracking discrepancies are immediately detected and corrected, maintaining high reliability in batch processing environments.
2Adaptability or versatility
If manual tissue staining processes are used, then flexibility in handling diverse patient cases is maintained, but workflow coordination efficiency deteriorates due to lack of automated information management
Solution Approach 1:
The system enables self-service information management where the LIS automatically generates slide labels with unique identifiers and staining protocols based on cassette data. Technicians simply scan barcodes and attach labels without manual data entry or coordination. The system autonomously tracks and coordinates workflow stages, eliminating time-consuming manual coordination while preserving the ability to handle diverse case requirements through flexible protocol assignment.
3Reliability
If comprehensive sample tracking is implemented across the entire staining process, then sample tracking accuracy is improved, but system complexity increases due to integration of multiple information management components
Solution Approach 1:
The patent employs universal barcode labels that serve multiple functions throughout the workflow: identification, tracking, and protocol specification. The same barcode system is used across different stages (cassette accessioning, slide labeling, staining processing) and integrates with the existing LIS infrastructure. This multi-functional approach achieves comprehensive tracking without requiring separate complex systems for each workflow stage, reducing overall system complexity while maintaining high tracking accuracy.
Data Source
AI summary
An embodiment of the method of the invention is a method of automating information flow in a laboratory performing tissue staining comprising positioning a networked label printer adjacent to a cutting station, the printer configured to access patient data directly or indirectly from the hospital LIS, the printer being configured with a data element scanner in electronic communication with said printer; inputting data from a tissue cassette-associated data element at said printer, whereby inputting data comprises reading the data from the cassette-associated data element and uploading the cassette data to the LIS; identifying the corresponding test protocol identifier and then downloading the test protocol data to the printer; printing information on labels corresponding to each test specified in the LIS for the patient; attaching a single label to each slide; and cutting a tissue section for each labeled slide and mounting the section on the slide.
