Solution Overview

Problem

Existing dialysis systems face challenges in ensuring comprehensive operator information while preventing erroneous inputs and malfunctions, particularly due to limitations in data display and transfer security.

Innovation Solution

The medical treatment system incorporates a touch screen input/display device with separate modes for machine-related and patient-related data, ensuring all patient data is displayed without overlap or error, using a centralized server for data storage and communication via HTTP/HTTPS protocols, and employing dynamic, interactive program sequences for patient information management.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If patient-related data records are displayed in a shared display area alongside machine-related data, then the operator can see all information in one place, but data records may overlap or be displayed incompletely within the limited display area

Engineering Contradiction:

Improvecompleteness of patient data displayVSAvoiddata display management complexity

Core Design Contradiction:

Loss of informationVSDevice complexity

Solution Approach 1:

The display area is segmented into a machine-related data area and a patient-related data area, with each type of data record displayed in its designated zone. This spatial segmentation prevents overlap between machine data and patient data, ensuring complete and organized display of all information without requiring complex overlay management.

Inventive Principle:

Principle #1Segmentation

2Loss of information

If all patient-related data records are displayed within the limited screen area, then comprehensive information is provided to the operator, but data overlap and display errors occur

Engineering Contradiction:

Improveinformation availability to operatorVSAvoiddisplay accuracy and positioning precision

Core Design Contradiction:

Loss of informationVSManufacturing precision

Solution Approach 1:

The display area is divided into distinct zones for machine-related data and patient-related data. This segmentation ensures that patient data records are displayed in a dedicated area with sufficient space, preventing overlap and display errors while maintaining complete information availability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system performs preliminary checks to determine whether patient data records can be completely displayed within the patient-related data area before displaying them. This preliminary action prevents display errors by identifying and managing data that would otherwise overlap or be truncated.

Inventive Principle:

Principle #10Preliminary action

3Ease of operation

If machine control data and patient information are displayed together, then the interface is unified, but the operator may misinterpret data or make erroneous inputs

Engineering Contradiction:

Improveinterface unity and accessibilityVSAvoidoperational safety and data interpretation accuracy

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The display interface is segmented into functionally distinct areas: a machine-related data area for control parameters and a patient-related data area for patient-specific information. This segmentation maintains interface unity while preventing misinterpretation by clearly separating data types and their purposes.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different display areas are assigned different functional qualities: the machine-related data area is optimized for control and adjustment, while the patient-related data area is optimized for information display only. This local quality differentiation ensures that patient data is viewed but not accidentally modified, enhancing operational safety.

Inventive Principle:

Principle #3Local quality

4Loss of information

If data transfer between treatment devices and server is increased for comprehensive patient information, then complete patient data is available, but security risks and potential malfunctions increase

Engineering Contradiction:

Improvecompleteness of patient dataVSAvoiddata transfer security and system stability

Core Design Contradiction:

Loss of informationVSReliability

Solution Approach 1:

The data transfer system is segmented into different data categories with appropriate security measures for each. Patient-related data transferred to the display device is separated from machine control data, with specific security protocols applied to patient information to ensure complete data availability while maintaining security and system stability.

Inventive Principle:

Principle #1Segmentation

AI summary

The invention relates to a medical treatment system, which comprises at least one device for carrying out medical treatment, in particular dialysis treatment and a device for providing patient-related data (server). The patient-related data is not stored in the dialysis device but loaded by the server. The data can be displayed in a patient mode on a screen. The dialysis system comprises various security features, which prevent an erroneous input and the erroneous display of patient-related data in the patient mode on the screen.
