Mattress Turn-and-Hold Pause Control Using Caregiver Force Sensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Caregivers face challenges in effectively pausing a turn and hold operation on person support apparatuses with mattress replacement systems, particularly in acute care settings, as existing methods require manual intervention and may disrupt the stabilization of patients.
Innovation Solution
A method and system that automatically pause a turn and hold operation by inflating air bladders on one side of the mattress, using sensors to detect force applied by caregivers, and a microcontroller to determine if the force duration exceeds a threshold, triggering a pause event and discontinuing inflation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual control methods are used for pausing turn and hold operation, then caregivers can control the operation, but caregivers must leave the individual's side to operate controls
Solution Approach 1:
The mattress replacement system performs the pausing function automatically through force sensors detecting caregiver presence and microcontroller processing, eliminating the need for manual control box operation and allowing continuous caregiver contact with the individual
Solution Approach 2:
Force sensors provide real-time feedback about caregiver presence and mattress deformation during the turn and hold operation, enabling automatic detection of pause requests without requiring caregivers to leave the individual's side
2Reliability
If force sensors and microcontrollers are added to enable automatic pause detection, then caregivers can maintain continuous contact with individuals, but device complexity increases
Solution Approach 1:
The force sensors serve multiple functions: detecting caregiver presence, monitoring mattress deformation, and triggering pause events, while the microcontroller integrates with the existing pump control system to manage both turn/hold operations and pause functionality through a unified control architecture
Solution Approach 2:
The pause detection functionality is merged into the existing mattress replacement system by integrating force sensors with the pump control circuit board and microcontroller, combining multiple functions (turn, hold, and pause detection) into a single coordinated system rather than separate independent systems

Function Achieved in This Case
Enables caregivers to pause the turn and hold operation without leaving the patient's side, maintaining support and stability, and allowing for continued care during the pause, enhancing operational efficiency in acute care settings.
Implementation Method 1
inflating, automatically with a pump, at least one air bladder in only one of a right side portion and a left side portion of the mattress replacement system
Implementation Method 2
detecting, automatically with at least one sensor, a force applied to at least one of a frame of the person support apparatus and the at least one air bladder

AI summary
A method for triggering a pause event in a turn and hold operation applied to a mattress replacement system of a person support apparatus may include inflating at least one air bladder in only one of a right side portion and a left side portion of the mattress replacement system; detecting, automatically with at least one sensor, a force applied to at least one of a frame of the personal support apparatus and the at least one air bladder as the at least one air bladder is inflated; determining, automatically with a microcontroller communicatively coupled to the at least one sensor, if the force applied has a force duration that is greater than a threshold force duration to trigger the pause event; and discontinuing inflation of the at least one air bladder when the pause event is triggered.
