Hospital Bed Alert Light Zones for Remote Condition Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current alert lights on hospital beds are not sufficiently informative, as caregivers cannot determine which specific condition is causing an alert without a visual inspection, leading to inefficiencies in identifying and addressing issues.
Innovation Solution
A patient support apparatus with an alert light assembly featuring separate zones that can be individually illuminated, each with a lens and indicia to indicate specific alert conditions, allowing for clear identification of issues from a distance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a single alert light is used to indicate multiple conditions, then the device complexity is reduced, but the information conveyed is insufficient and caregivers cannot identify specific issues
Solution Approach 1:
The alert light assembly is segmented into multiple independently controllable light zones (e.g., first zone, second zone, third zone) where each zone corresponds to a specific monitored condition. This segmentation allows each zone to independently indicate the status of different conditions, providing detailed information without requiring a single complex indicator system.
Solution Approach 2:
Each light zone is assigned a specific function and spatial position within the assembly, with lights arranged in a predetermined pattern. The local quality of each zone (its position, color, and activation condition) provides specific information about particular bed conditions, allowing caregivers to identify issues by observing which specific zone is illuminated.
2Illumination intensity
If small LED lights are used, then the device complexity is low, but the lights cannot be seen from a distance
Solution Approach 1:
Multiple light-emitting components are merged into a single integrated alert light assembly that is mounted on the bed frame. This consolidation provides the benefits of multiple indicators while maintaining a unified, space-efficient structure that does not add excessive complexity to the overall device.
3Loss of information
If multiple monitored conditions are indicated by one light color, then the device complexity is reduced, but the specificity of alert information is lost
Solution Approach 1:
The alert light assembly is segmented into multiple independently controllable light zones (e.g., first zone, second zone, third zone) where each zone corresponds to a specific monitored condition. This segmentation allows each zone to independently indicate the status of different conditions, providing detailed information without requiring a single complex indicator system.
Solution Approach 2:
Each light zone is assigned a specific function and spatial position within the assembly, with lights arranged in a predetermined pattern. The local quality of each zone (its position, color, and activation condition) provides specific information about particular bed conditions, allowing caregivers to identify issues by observing which specific zone is illuminated.

AI summary
A patient support apparatus, such as a hospital bed, includes an alert light assembly or an alert light module having separate zones that are individually illuminated to convey information regarding respective alert conditions. The zones each have indicia related to a particular condition of the patient support apparatus. The illuminated zones are each sufficiently large so as to be seen from afar, such as on the order of ten feet or more. Alternatively or additionally, a GUI of the patient support apparatus displays alert indicia as part of a screen saver. Further alternatively or additionally, the patient support apparatus illuminates an alert light in a manner indicating an optimal time for taking a patient's vital signs.
