Offline Analyzer Maintenance via Terminal Intermediary
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Analyzers in medical facilities, which are not connected to the Internet for security reasons, face challenges in obtaining and executing countermeasures for abnormalities without direct network communication, leading to delayed restoration and potential difficulties for inexperienced operators.
Innovation Solution
A maintenance method that involves a terminal connected to the network presenting information to an analyzer, allowing the analyzer to read and execute processes, enabling offline quality control and maintenance without external network communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the analyzer is not connected to the network outside the facility, then patient data security is ensured, but the ability to obtain countermeasure information for abnormalities is lost
Solution Approach 1:
The invention introduces a terminal device as an intermediary between the analyzer and external network resources. The terminal device stores countermeasure information locally and transmits it to the analyzer when needed, allowing the analyzer to obtain repair information without maintaining continuous network connectivity, thus preserving security while enabling access to countermeasure information.
Solution Approach 2:
The terminal device pre-stores countermeasure information for various abnormalities in its storage unit before they are needed. When an abnormality occurs, the analyzer can immediately retrieve the corresponding countermeasure information without needing to query external sources, enabling rapid response while maintaining network isolation.
2Reliability
If countermeasure information is obtained through telephone inquiry or waiting for service staff, then security is maintained, but restoration time increases
Solution Approach 1:
The analyzer is equipped with an abnormality countermeasure information acquisition unit that can autonomously retrieve countermeasure information from the terminal device without requiring human intervention such as telephone inquiries or waiting for service staff. This self-service capability significantly reduces restoration time while maintaining security by keeping the analyzer isolated from external networks.
Solution Approach 2:
The terminal device acts as a local information repository that the analyzer can query autonomously. This intermediary system enables the analyzer to self-diagnose and self-repair by obtaining countermeasure information locally, eliminating the need for external communication while maintaining security.
3Ease of repair
If countermeasure information is provided to inexperienced operators, then restoration can be attempted, but understanding and execution difficulty increases
Solution Approach 1:
The terminal device stores standardized countermeasure information that can be copied and transmitted to the analyzer. This information is pre-formatted and can be easily displayed to operators, providing clear, consistent instructions that reduce the cognitive load on inexperienced operators and facilitate proper execution of restoration procedures.
Solution Approach 2:
The system provides structured countermeasure information that can be systematically followed by operators. The information acquisition unit ensures that appropriate countermeasure information is delivered to the operator based on the specific abnormality detected, providing targeted guidance that improves understanding and execution even for inexperienced users.

AI summary
Disclosed is a maintenance method for an analyzer that is not communicably connected to a network outside of a facility, the maintenance method comprising: presenting, by a terminal that is communicably connected to the network outside of the facility, information about a process to be executed by the analyzer; reading, by the analyzer, the information having been presented by the terminal; and executing, by the analyzer, the process indicated by the information having been read.
