CPR Device Stabilization Strap for Stretcher Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual cardiopulmonary resuscitation (CPR) is labor-intensive and prone to fatigue, leading to inconsistent compressions, and existing mechanical CPR devices lack effective stabilization during patient transport or in confined spaces, which can affect the efficacy and safety of CPR.
Innovation Solution
A mechanical CPR device with a piston and suction cup for chest compressions, stabilized using adjustable straps and buckles that secure the device to a stretcher or patient, ensuring consistent operation and minimizing movement during transport or in tight spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual CPR is performed, then circulatory and respiratory functions can be maintained, but the procedure is labor-intensive and prone to fatigue leading to inconsistent compressions
Solution Approach 1:
The patent replaces the manual mechanical system of human operators performing CPR with an automated mechanical CPR device that uses a motor-driven piston to deliver compressions. This substitution eliminates human fatigue and maintains consistent compression depth and rate, directly resolving the contradiction between reliability and ease of operation.
2Reliability
If mechanical CPR device is used, then constant proper compressions can be provided without fatigue, but the device lacks stabilization during patient transport or in confined spaces
Solution Approach 1:
The stabilization system is segmented into multiple independent straps (first strap, second strap, third strap) that can be independently adjusted and secured. Each strap connects to different attachment points on the device and patient, distributing stabilization forces across multiple locations. This segmentation allows the device to remain stable during transport while maintaining compression reliability.
3Stability of the object's composition
If the device is secured tightly to ensure stability, then movement is minimized, but the complexity of securing and adjusting the device increases
Solution Approach 1:
The stabilization system incorporates adjustable straps with buckles that allow dynamic adjustment of tension and fit. The straps can be tightened or loosened depending on the specific situation (transport vs. stationary CPR), and the adjustable nature allows for quick adaptation to different patient sizes and device positions. This dynamic adjustability maintains stability while managing complexity through user-configurable settings.
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 stabilization system allows for consistent and effective mechanical CPR, reducing fatigue and improving safety by maintaining proper compression depth and frequency, even during patient transport or in confined areas.
Implementation Method 1
The piston may have a suction cup attached to an end of the piston for contacting the sternum/torso of a patient

AI summary
Techniques and devices for securing a medical device to a patient-carrying device, such as a mechanical CPR device to a stretcher, are described herein. In one aspect, a medical device stabilization strap may include a first removable attachment shackle connected to a first end of a first strap. An adjustable quick release buckle may be disposed between a second end of the first strap and a proximal end of a second strap. A second removable attachment shackle may be connected to a distal end of the second strap. The first and second removable attachment shackles may each include a U-shaped bracket for removably engaging a medical device. The adjustable quick release buckle may adjust a length of the second strap, for example, to secure the medical device to the patient-carrying device.
