Vital Sign Sensor Site Verification System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vital sign sensors are often mistakenly used at incorrect sites within medical facilities, leading to unintended variations in stock and potential misuse, as they can be moved between sites without proper site-specific compatibility checks.
Innovation Solution
A vital sign information processing system that includes a sensor with a memory storing site-specific information and an information acquisition apparatus with a processor that compares and matches site information, triggering notifications and restrictions if the sites do not match, thereby preventing erroneous use and maintaining accurate stock management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If sensors are made compatible with multiple information acquisition apparatus across different sites, then device versatility is improved, but the risk of erroneous use increases
Solution Approach 1:
The system implements a feedback mechanism where the information acquisition apparatus checks the site information stored in the sensor's memory against the current site's designated information. When a mismatch is detected, the system provides feedback through notifications to alert users of the erroneous use, thereby maintaining reliability while preserving versatility.
Solution Approach 2:
The system performs preliminary action by storing site information in the sensor's memory before use and by pre-configuring the information acquisition apparatus with designated site information. This preliminary setup enables automatic verification upon connection, preventing erroneous use before it can occur.
2Reliability
If site information verification is implemented, then sensor use accuracy is improved, but device complexity increases
Solution Approach 1:
The system implements self-service by having the sensor itself store and provide its designated site information through its memory, and by having the information acquisition apparatus automatically retrieve and verify this information without requiring manual intervention or complex external verification systems.
Solution Approach 2:
The system uses copying by storing site information in the sensor's memory as a copy of the designated site data, and by having the information acquisition apparatus store its own designated site information. This copying approach simplifies verification by comparing identical data structures rather than requiring complex authentication protocols.

AI summary
A vital sign information processing system includes a sensor configured to be attached to a living body, and an information acquisition apparatus configured to acquire vital sign information of the living body through the sensor. A first memory is disposed in the sensor and stores first site information indicative of a site at which the sensor is to be used. A second memory is disposed in the information acquisition apparatus and stores second site information indicative of a site at which the information acquisition apparatus is to be used. A processor disposed in the information acquisition apparatus causes the information acquisition apparatus to perform notification when the first site information and the second site information are not matched.
