Patient Support Bed Control With Visual Deck Position Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing patient supports, such as hospital beds, lack advanced control systems for enhanced functionality and patient monitoring, leading to suboptimal care and inefficiencies in healthcare delivery.
Innovation Solution
A patient support system equipped with a controller that integrates user interfaces, sensors, and actuators to provide enhanced control over bed functions, monitor patient conditions, and deliver prompts for care protocols, while allowing data collection and remote monitoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a controller with stored prompts and user interface is integrated into the patient support, then control over patient support functions and patient monitoring is enhanced, but device complexity increases
Solution Approach 1:
The controller is designed to perform multiple functions including storing and managing care protocols, generating timed prompts, collecting patient data, communicating with remote devices, and controlling patient support functions. This multi-functionality consolidates what would otherwise require separate systems into a single integrated controller, improving reliability while managing complexity through functional consolidation.
2Reliability
If multiple sensors and monitoring devices are added to the patient support, then patient monitoring capability is improved, but device complexity increases
Solution Approach 1:
The controller serves as an intermediary that receives data from multiple sensors and monitoring devices, processes this information, and presents it in a unified manner. This mediator approach allows multiple sensing elements to be integrated without proportionally increasing system complexity, as the controller handles the complexity of data aggregation and interpretation centrally.
3Productivity
If automated prompts and protocols are implemented, then productivity of care delivery is improved, but ease of operation decreases
Solution Approach 1:
Care protocols and prompts are pre-programmed into the controller with specific timing and conditions. This preliminary action allows the system to automatically execute care tasks at appropriate times without requiring real-time manual planning, improving productivity while presenting a simplified interface that primarily requires users to review and acknowledge prompts rather than manually orchestrate complex sequences.
4Loss of information
If data collection and remote monitoring capabilities are added, then information availability is improved, but loss of information handling complexity increases
Solution Approach 1:
The controller implements bidirectional communication capabilities that provide feedback between the local patient support system and remote monitoring devices. This feedback mechanism ensures that patient data is continuously transmitted and updated, improving information availability while managing data handling complexity through structured communication protocols that automatically manage data flow and synchronization.

AI summary
A patient support apparatus includes a deck to support a mattress and a patient on the mattress, the deck including a head deck section articulatable about an axis to change an angle of the head deck section, and a control system in communication with a user interface, with the control system configured to adjust the angle of the head deck section and to adjust the height of the deck in response to input at the user interface. The control system is in communication with a display and generates a GUI (graphical user interface) at the display to display a deck icon representative of the deck and a height icon representative of the height. The control system monitors the angle of the deck section and the height of the deck and adjusts the deck and height icons to schematically illustrate the adjustments made to the height of the deck and the angle of the head deck section to provide visual feedback to a user of the changes in height of the deck and/or angle of the head deck section in response to the user's input at the user interface.
