Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current blood treatment machines face challenges in ensuring easy and reliable data entry and storage, particularly for safety-critical parameters, which can lead to errors affecting patient health if not properly verified.
Innovation Solution
The medical apparatus employs a control system with a main control unit that displays parameters on a user interface, allowing selection and entry of values, with automated verification by capturing screen data and comparing it to stored values in a second memory, reducing the need for user verification and minimizing errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If automated verification is implemented, then data entry reliability is improved, but device complexity increases
Solution Approach 1:
The patent creates a copy of the displayed parameter value and stores it in a second memory location. The control system then automatically compares the value in the first memory with the copied value from the second memory to verify data entry accuracy, eliminating the need for user verification while maintaining system reliability.
Solution Approach 2:
The control system automatically generates feedback by comparing the displayed parameter value with the stored value and determining whether they match. This automated feedback mechanism verifies data entry reliability without requiring user intervention, though it does increase control system complexity through the additional comparison logic.
2Reliability
If user verification is required, then data entry reliability is improved, but ease of operation deteriorates
Solution Approach 1:
The control system performs self-verification by automatically comparing the displayed parameter value with the stored value in the second memory. This self-service mechanism eliminates the need for user verification actions, significantly improving ease of operation while maintaining data entry reliability through automated checking.
Solution Approach 2:
The system provides automated feedback by comparing parameter values and determining matches without user intervention. This feedback mechanism ensures reliability while improving operational ease, as users simply need to enter values without performing additional verification steps.
3Reliability
If manual verification is implemented, then data entry reliability is improved, but loss of time increases
Solution Approach 1:
The control system continuously monitors and compares parameter values in the background, maintaining continuous verification without interrupting the data entry flow. This continuous useful action ensures reliability while minimizing time loss, as verification occurs automatically during normal operation rather than requiring separate verification steps.
Solution Approach 2:
The automated feedback mechanism compares values instantly upon data entry, providing immediate verification without requiring additional user time. The control system continuously checks for matches between displayed and stored values, ensuring reliability while reducing verification time through rapid automated comparison.

AI summary
A medical apparatus comprises a user interface for setting parameters and includes: a screen for visualizing values of said parameters, a main control unit connected to the interface, a first memory and a video memory both connected to the main control unit for storing data corresponding to images on screen; the main control unit allows setting of a new value for a parameter, displays the new value on a screen region, stores the new value in the first memory, captures from the video memory data representative of said screen region, verifies from said representative data if the displayed value corresponds to the value in the first memory. A method for setting up a medical apparatus is also disclosed.
