Patient support apparatus with notification system
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current patient support apparatuses lack an efficient mechanism to notify caregivers about the status of the mattress, particularly after cardiopulmonary resuscitation (CPR) treatments, which can lead to improper resetting of the mattress state, potentially affecting patient comfort and safety.
Innovation Solution
A patient support apparatus with an inflatable mattress portion and a control system that allows users to select and control the inflation or deflation of the mattress, including a notification system to remind caregivers to change the mattress state, utilizing a pneumatic system with a CPR valve and sensors to detect CPR events and automatically reset the mattress to its pre-treatment state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a notification system is added to alert caregivers about mattress status, then patient safety and caregiver awareness are improved, but device complexity increases
Solution Approach 1:
The notification system is merged with the existing control system and user interface of the patient support apparatus. The control system that already manages mattress inflation/deflation is extended to include notification generation and display functions, integrating multiple functions into a unified system rather than adding separate independent components.
Solution Approach 2:
The user interface serves multiple functions: it allows caregivers to manually control mattress inflation/deflation and simultaneously displays notifications about mattress status and CPR events. This multi-functional design eliminates the need for separate notification devices and reduces overall system complexity.
2Reliability
If automatic mattress resetting after CPR is implemented, then patient comfort and safety are improved, but device complexity and energy consumption increase
Solution Approach 1:
The system performs preliminary detection of CPR events during the treatment process. Sensors continuously monitor mattress conditions and detect when CPR is being administered, preparing the system in advance to automatically reset the mattress after the event, eliminating the need for manual intervention and ensuring patient safety.
Solution Approach 2:
The system uses sensors to provide continuous feedback about mattress conditions and CPR events. This feedback loop enables the control system to automatically detect when CPR has occurred and when the mattress needs to be reset, allowing the system to self-regulate and reduce energy consumption by only activating when necessary.
3Device complexity
If manual mattress state changes are required after CPR, then device complexity is reduced, but loss of time and productivity decrease
Solution Approach 1:
The system provides self-service by automatically detecting CPR events and initiating mattress reset procedures without requiring manual caregiver intervention. The control system monitors sensor data, determines when CPR has occurred, and automatically adjusts the mattress back to its pre-treatment state, saving time and improving efficiency.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Ensures proper notification to caregivers about the mattress state, facilitating timely adjustments and improving patient safety by automatically resetting the mattress to its pre-treatment configuration after CPR, thereby enhancing patient comfort and care.
Implementation Method 1
The control system comprises a pneumatic system with one or more fluid flow devices to inflate or deflate the inflatable mattress portion
Implementation Method 2
the pneumatic system includes a CPR valve that is actuatable between a closed configuration where the flow of air from the inflatable mattress portion is blocked at the CPR valve, and an open position where the air can flow from the inflatable mattress portion to atmosphere through the CPR valve

AI summary
A patient support apparatus for supporting a patient includes a mattress with an inflatable mattress portion with a plurality of states. The apparatus further includes a control system to control inflation or deflation of the mattress portion to change its state between two or more of the states. The apparatus further includes a user interface in communication with the control system, which is configured to allow a user to select an inflate or deflate function of the mattress portion to change the state of the mattress portion. Further, the control system is operable to inflate or deflate the mattress portion in response to the signal being generated when a user selects an inflate or deflate function at the user interface. The control system is configured to generate a notification indicative of the selected state of the mattress portion to remind to a caregiver to change the selected state.
