Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vaccination accidents due to misvaccination and misregistration of vaccines occur during the vaccination process, leading to incorrect administration and registration of vaccines, which can result in adverse events.
Innovation Solution
A vaccine management system comprising on-site vaccination information recognition devices and terminals that verify subject identification and vaccine information, displaying confirmation information on a screen to ensure accurate vaccine administration and registration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual vaccine registration and verification processes are used, then the vaccination service can be provided quickly, but vaccination accidents such as misvaccination and misregistration occur
Solution Approach 1:
The patent replaces manual mechanical verification processes with an automated information recognition system. The recognition device automatically captures and processes vaccine information (lot number, expiration date, etc.) from the vaccine packaging, eliminating manual entry and verification by medical staff. This substitution of mechanical/manual operations with automated recognition technology improves vaccination accuracy while managing system complexity through standardized automation.
2Reliability
If automated information recognition is implemented, then misvaccination and misregistration are prevented, but the device and process complexity increases
Solution Approach 1:
The patent introduces an intermediary verification terminal that acts as a mediator between the information recognition device and the vaccine administration process. The terminal receives recognized information, performs verification against the vaccination schedule, and provides confirmation to medical staff. This intermediary layer manages complexity by centralizing verification logic and providing a user-friendly interface, rather than embedding complex verification directly in the recognition device or requiring staff to manage multiple separate systems.
Solution Approach 2:
The system implements feedback mechanisms where the verification terminal provides real-time confirmation or alerts to medical staff about vaccine-schedule matching. The system compares recognized vaccine information with the pre-registered vaccination schedule and provides immediate feedback on whether the vaccine is correct, expired, or mismatched. This feedback loop ensures high reliability by preventing incorrect vaccinations while managing complexity through automated comparison logic rather than requiring manual cross-checking procedures.
3Reliability
If multiple verification steps are added to confirm vaccine information, then vaccination accuracy improves, but the vaccination process time increases
Solution Approach 1:
The patent implements preliminary action by pre-registering vaccination schedules and vaccine information in the system before the actual vaccination occurs. The system stores the intended vaccine type, lot number, and expiration date in advance. During vaccination, the recognition device simply compares the actual vaccine against this pre-prepared information, enabling rapid verification without requiring multiple sequential verification steps. This preliminary preparation of verification criteria significantly reduces the time required during the actual vaccination process while maintaining high accuracy.

AI summary
There are disclosed system and method for preventing vaccination accidents due to misvaccination and misregistration of vaccines. The system comprises: an on-site vaccination information recognition device for recognizing a subject identification code of a subject to be vaccinated and information on vaccine for vaccination printed on a syringe or vial; and an on-site terminal for displaying check information that must be confirmed for vaccination of the subject to be vaccinated based on the subject identification code and information on vaccine for vaccination transmitted from the on-site vaccination information recognition device, on a screen. The screen of the on-site terminal includes: a first display area for displaying the identity information of the subject to be vaccinated corresponding to the subject identification code of the check information; and a second display area for displaying the vaccination information corresponding to the information on vaccine for vaccination of the check information.
