Bedside Handle Laser Monitoring for Silent Bed-Exit Alerts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional side rails and pressure-pad alarms in nursing homes are considered restraints, leading to increased patient fall rates and difficulties in detecting bed exits, while position change alarms can inhibit patient movement and create noise disturbances.
Innovation Solution
A bedside handle system with integrated laser technology for motion detection and wireless communication, allowing safe patient monitoring and assistance request features, including motion detection and wireless alerts for staff, with a user-friendly app for surveillance customization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional side rails are removed to eliminate restraint, then patient freedom of movement is improved, but patient fall rate increases
Solution Approach 1:
The patent replaces the mechanical side rail system with a laser-based detection system. The laser transmitter and receiver create an invisible beam that detects patient movement and position changes, eliminating the need for physical side rails while maintaining safety monitoring through wireless communication alerts to staff.
Solution Approach 2:
The patent introduces a laser beam as an intermediary between the patient and the monitoring system. This invisible laser field acts as a mediator that detects patient presence and movement without physical contact, allowing patients to move freely while triggering alerts when they leave the designated bed area.
2Reliability
If position change alarms are installed to detect patient movement, then patient safety is improved, but noise disturbance increases and patient movement is inhibited
Solution Approach 1:
The patent replaces traditional acoustic position change alarms with a laser-based detection system. The laser beam provides silent detection of patient movement and position changes, eliminating noise disturbances while maintaining effective monitoring through wireless communication that alerts staff without audible signals.
3Reliability
If traditional pressure-pad alarms are used to detect patient movement, then patient safety is improved, but the alarm is loud and creates disturbance
Solution Approach 1:
The patent replaces the pressure-pad alarm system with a laser-based detection system. The laser transmitter and receiver create an invisible detection field that provides silent monitoring of patient movement, eliminating the loud noise associated with traditional pressure-pad alarms while maintaining effective safety monitoring.
