Medical Terminal Device Operator Identification Screen
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multi-operator medical environments, existing systems struggle to accurately identify and manage which operator is using which medical device, leading to potential unintended operation control issues.
Innovation Solution
A medical terminal device with an operation display unit, operator identification means, patient identification means, and device identification means, along with information storage and control mechanisms, ensures correct identification and operation of medical devices based on operator, patient, and device information, displaying tailored operation screens for each medical care scenario.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single operation terminal operates multiple medical care devices, then the number of operation terminals is reduced, but it becomes difficult to control which operator uses which medical care device for which medical care
Solution Approach 1:
The system implements feedback mechanisms by displaying identification information of operators, patients, and medical care devices on the operation terminal screen. The control unit continuously monitors and updates the display to reflect current operational status, ensuring that operators can verify they are controlling the intended device. This feedback loop resolves the contradiction by maintaining operational simplicity while enhancing control accuracy through real-time information feedback.
Solution Approach 2:
The operation terminal serves as an intermediary device that mediates between multiple operators and multiple medical care devices. It establishes unique associations between operators, patients, and devices through identification information, acting as a central coordinating interface. This intermediary function allows a single terminal to manage multiple devices reliably by preventing direct ambiguous access and enforcing controlled, traceable operations.
2Productivity
If multiple operators perform medical care on their own patients simultaneously, then patient care efficiency is improved, but unintended operation control on wrong medical care devices may occur
Solution Approach 1:
The system segments the operational context by dividing identification information into distinct components: operator identification, patient identification, and medical care device identification. Each operator-patient-device combination is uniquely identified and managed separately. This segmentation allows multiple operators to work simultaneously on different patients with different devices without confusion, as each operational thread is independently tracked and displayed, preventing unintended control while maintaining high productivity.
Solution Approach 2:
The system uses visual differentiation (analogous to color changes) by displaying distinct identification information for different operators, patients, and devices on the operation terminal. Different combinations are presented with unique visual identifiers, allowing operators to quickly distinguish their assigned device from others. This visual coding system prevents unintended operations by making the current operational context immediately recognizable, even during simultaneous multi-operator usage.

AI summary
An object is to provide a medical terminal device that specifies an operator, a patient and a medical care device to be used so that correct medical care can be performed in accordance with the operator and the patient by use of the desired medical care device, and a medical care system including such a medical terminal device. A medical system 1 includes a multi-controller 10 including a plurality of medical care devices 100; a storage unit 403 that stores operator information, patient information and device information; and a control unit 12 that, based on the operator information, the patient information and the device information, displays an operation screen 20 on the medical care device 100 to be used for medical care such that the operation screen 20 reflects a setting made by the operator to perform the medical care and a setting made by the patient to receive the medical care, the operation screen 20 being displayed on an operation display unit.
