Tourniquet Timer Apparatus for Accurate Time Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional emergency tourniquets lack accurate and reliable means to record and track the duration of application, which is critical for minimizing risks associated with prolonged ischemia and ensuring proper patient care, especially in high-stress field settings where handwritten records are often illegible or lost.
Innovation Solution
A tourniquet system incorporating a flexible band, a tensioning device, and a tamper-proof timer apparatus that includes a housing, display, power supply, and microcontroller to accurately measure and display elapsed time, designed for single-handed application and resistance to environmental factors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional emergency tourniquet is used, then the tourniquet can be applied quickly and is lightweight, but it lacks accurate and reliable means to record and track application time
Solution Approach 1:
The tourniquet system integrates multiple functions into a single device: the flexible band provides mechanical constriction while the integrated timer apparatus provides time tracking. This multi-functionality resolves the contradiction by combining reliable time recording with the existing tourniquet structure, eliminating the need for separate recording methods.
Solution Approach 2:
The timer apparatus is integrated directly with the flexible band of the tourniquet, merging the timing function with the constriction function. This integration ensures that the time recording travels with the tourniquet and cannot be lost or separated, thereby improving reliability without significantly increasing overall device complexity.
2Reliability
If handwritten time recording is used on the tourniquet, then the device remains simple, but the recording is often illegible or lost
Solution Approach 1:
The manual handwriting system is replaced with an electronic timer apparatus that automatically records and displays time. This substitution eliminates the problems of illegibility and loss associated with handwritten records, providing accurate and reliable time tracking while maintaining ease of operation through automatic functioning.
Solution Approach 2:
The timer apparatus operates automatically upon application of the tourniquet, requiring no manual intervention for time recording. This self-service capability ensures that time is accurately tracked without adding operational complexity, resolving the contradiction between reliability and ease of operation.
3Measurement precision
If a timer apparatus is integrated with the tourniquet, then accurate time tracking is achieved, but the device complexity increases
Solution Approach 1:
The timer apparatus is designed as a self-contained unit with specific local functions (power supply, display, microcontroller) that are integrated with the flexible band. This localized integration provides precise time measurement while containing the complexity within a discrete component, minimizing the impact on overall device simplicity.
