Solution Overview
Problem
Existing methods for associating biological values measured by devices with patients require pre-registration and special operations, increasing complexity and cost due to the need for IC tag reading and separate reading devices.
Innovation Solution
A control apparatus that authenticates measurement devices by comparing unique information inputted with stored information, allowing for the association of measurement values with patients without pre-registration, using an input unit, storage unit, computation unit, authentication unit, processing unit, and output unit for storing and authenticating measurement values.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If an IC tag reading technique is used to associate measurement values with patients, then patient identification accuracy is improved, but device complexity and operational complexity increase due to the need for separate reading devices and pre-registration operations
Solution Approach 1:
The patent merges the IC tag reading function directly into the measurement device, eliminating the need for separate reading devices. The measurement device includes both the measurement function and the IC tag reading function, allowing it to autonomously read patient identification information and associate measurement values with patients without external assistance.
Solution Approach 2:
The measurement device is designed with multi-functionality, serving both as a measurement instrument and as an IC tag reading device. This universal design allows the same device to perform patient identification and biological measurement functions, reducing overall system complexity while maintaining accurate patient identification.
2Measurement precision
If IC tag reading operations are performed each time a measurement is taken, then patient association accuracy is improved, but operational complexity increases due to manual reading and pre-registration requirements
Solution Approach 1:
The measurement device performs self-service by autonomously reading IC tags and associating measurement values with patients without requiring manual intervention. The device automatically executes the patient identification and data association processes, eliminating the need for operator involvement in these tasks.
Solution Approach 2:
The system performs preliminary actions by pre-storing correspondence relationships between IC tag information and patient identification information in the measurement device. This pre-registration of association data eliminates the need for manual pre-registration operations during actual measurements, simplifying the workflow while maintaining accurate patient association.
3Adaptability or versatility
If separate reading devices are provided for IC tag reading, then patient identification capability is improved, but costs increase due to additional hardware requirements
Solution Approach 1:
The patent combines the IC tag reading functionality with the measurement device, eliminating the need for separate reading devices. This integration reduces hardware requirements and associated costs while maintaining the capability to read IC tags and identify patients accurately.
Solution Approach 2:
The measurement device is designed as a universal device that performs both measurement and IC tag reading functions. This multi-functionality eliminates the need for additional dedicated reading devices, reducing overall system costs while preserving patient identification capabilities.
Data Source
AI summary
A blood pressure meter, a thermometer, and a pulse oximeter are connected to the control apparatus, and the control apparatus includes an input unit configured to wirelessly input information identifying a measurement time and unique information along with the measurement value from the measurement devices, a processing unit configured to store the inputted measurement value and unique information in a memory, and an authentication unit configured to authenticate the measurement device that inputted the measurement value as being the same as a measurement device that inputted a stored measurement value by comparing the unique information with unique information stored along with a measurement value measured prior to the inputted measurement value. Here, the processing unit is configured to store the inputted measurement value in the case where the authentication succeeds.
