Mattress function indicator on graphical user interface for bed
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current patient support apparatuses lack an effective graphical user interface for seamlessly controlling and monitoring the mattress function state, particularly in managing microclimate conditions, which is crucial for patient comfort and preventing pressure ulcers.
Innovation Solution
A patient support apparatus equipped with a graphical user interface that includes a controller to selectively display screens for mattress function settings, allowing users to activate or deactivate the microclimate management system, with features like icons for indicating the system's status and remote access for authorized personnel, ensuring efficient operation and user safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a graphical user interface is provided with multiple screens and icons for mattress function control, then user control and monitoring capability is improved, but interface complexity increases
Solution Approach 1:
The graphical user interface is segmented into multiple functional screens (home screen, mattress function screen, microclimate management screen) with dedicated icons for different control functions. This segmentation allows complex mattress functions to be organized into manageable, intuitive sections rather than presenting all controls on a single complex interface.
Solution Approach 2:
The graphical user interface acts as an intermediary layer between the user and the complex pneumatic system controls. By providing visual icons and structured screens, it mediates the interaction complexity, allowing users to control mattress functions without directly interfacing with the underlying complex system architecture.
2Ease of operation
If control inputs are enabled on the home screen for direct mattress function adjustment, then user accessibility is improved, but risk of unauthorized or incorrect operation increases
Solution Approach 1:
The control input availability is made dynamic rather than static. The system automatically enables or disables control inputs on the home screen based on detected user characteristics (such as whether the user appears to be a healthcare professional). This dynamic adaptation allows the interface to provide easy access when appropriate while preventing unauthorized changes when inappropriate.
Solution Approach 2:
The system changes the operational parameter of control input availability based on user identification. When a healthcare professional is identified, control inputs are enabled; when a patient or unauthorized user is identified, control inputs are disabled. This parameter change resolves the contradiction by adapting accessibility to the appropriate security level.
3Adaptability or versatility
If the system provides detailed mattress function controls, then functionality is improved, but device complexity increases
Solution Approach 1:
The control system adds a dimensional layer of organization by implementing a multi-screen hierarchical structure. Instead of presenting all controls in a single flat interface, the system organizes controls across multiple dimensional layers (home screen with main functions, mattress function screen with detailed controls, microclimate management screen with specialized controls), making the complex functionality more manageable and understandable.

AI summary
A patient support apparatus (10) may include a mattress (14) configured to receive a fluid from a pneumatic system (56), a graphical user interface (30), and a controller (20) configured to control the pneumatic system (56) and to communicate with the graphical user interface (30). The controller (20) may control the graphical user interface (30) to selectively display a home screen (32) comprising a plurality of icons, the icons comprising a mattress function menu icon (212) and a mattress function screen (36) accessible via the mattress function menu icon (212). The mattress function screen (36) may include at least one control input configured to activate a first state and a second state of the controller (20). In the first state, the controller (20) may be configured to display and enable a user input at the home screen (32), wherein in response to the user input, the controller (20) performs an instruction configured to adjust a setting of the pneumatic system (56). In the second state, the controller (20) may be configured to suppress the display of and disable the user input at the home screen (32).
