Tracheostomy Collar Sensor Detects Tube Displacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Tracheostomy tubes are prone to dislodgment, which can lead to inadequate oxygen supply and serious injury or death, as existing securing methods are not sufficiently secure or reliable, and there is a need for a system to alert caregivers of tube movement.
Innovation Solution
A securing collar or band with integrated sensor and alarm assemblies using wireless communication technology to monitor and detect movement of the tracheostomy tube, alerting medical personnel through audio and visual signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a tracheostomy tube is secured using traditional methods (cloth ties or Velcro straps), then the tube can be attached to the patient's neck, but the securing method is not sufficiently secure or reliable and the tube can become dislodged
Solution Approach 1:
The patent combines the securing collar with integrated sensor assemblies and alarm systems into a single unified device. The collar incorporates multiple sensors (accelerometers, gyroscopes, magnetometers) and communication modules that work together to detect tube displacement and alert medical personnel, creating a integrated safety system that goes beyond traditional securing methods.
Solution Approach 2:
The system implements continuous monitoring through sensors that detect tube position and movement, providing real-time feedback to medical personnel via alarm notifications. When the sensor detects that the tube has moved beyond a predetermined threshold, it immediately triggers an alert, allowing for rapid response to potential dislodgment.
2Loss of information
If traditional securing methods are used, then the device is simple to operate, but there is no means to alert caregivers when the tube is dislodged
Solution Approach 1:
The patent replaces traditional mechanical securing methods with electronic sensing and wireless communication systems. Instead of relying solely on physical restraint, the system uses accelerometers, gyroscopes, and magnetometers to detect tube displacement, and employs wireless communication modules to transmit alerts to medical personnel's electronic devices.
Solution Approach 2:
The monitoring system operates autonomously, with sensors continuously detecting tube position and automatically triggering alarms when displacement is detected. The system self-monitors without requiring constant manual inspection by caregivers, providing continuous surveillance and immediate notification of potential issues.
3Reliability
If the tube is made more secure with additional constraints, then dislodgment is prevented, but patient comfort and ease of operation may be reduced
Solution Approach 1:
The securing system is divided into modular components including the collar, sensor assemblies, and alarm system. This segmentation allows the tube to be secured firmly while distributing the monitoring and alerting functions across separate integrated modules, maintaining patient comfort through proper design of each individual component.
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
The system effectively prevents tracheostomy tube movement, detects and reports any accidental decannulation, and transmits alerts to electronic devices, reducing the risk of injury to patients by ensuring the tube remains securely in place.
Implementation Method 1
a sensor component and an actuator component each located proximate the faceplate
Implementation Method 2
The alarm assembly is configured to produce an alert in response to receiving the signal from the sensor component
Implementation Method 3
transmits alerts to electronic devices

AI summary
A device to monitor movement of a tracheostomy tube is described. The device includes a faceplate that is releasably attached to a tracheostomy collar such that the faceplate may be used without the tracheostomy collar. The tracheostomy collar includes a sensor component and an actuator component each located proximate the faceplate. The actuator component actuates when the sensor component moves from a first position to a second position. The second position is further from the actuator component than the first position. The sensor component transmits a signal to an alarm assembly in response to the actuator component actuating. The alarm assembly produces an alert in response to receiving the signal from the sensor component.
