Solution Overview
Problem
Existing CPR devices for cardiac arrest treatment are not simple to operate and may not effectively secure patients during compressive massage, leading to inefficiencies in delivering adequate blood flow to essential organs.
Innovation Solution
A patient reanimation apparatus with a plunger driven by a motor for compressive massage, featuring a position measuring device, securing straps, and a vertically adjustable holding device with a cross-member or curved support, which forms a force-locked structure to absorb forces and ensure proper positioning and stability during treatment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed holding device is used for the drive means and plunger, then the structure is simple, but the device cannot be adjusted to different patient sizes and treatment positions
Solution Approach 1:
The holding device incorporates vertically adjustable components that allow the drive means and plunger to be repositioned along the reanimation board. This dynamic adjustment capability enables adaptation to different patient sizes and treatment requirements while maintaining a relatively simple overall structure through standardized adjustment mechanisms.
Solution Approach 2:
The holding device is divided into modular components including the reanimation board, adjustable support structures, and detachable drive means mounting. This segmentation allows independent adjustment of each component to achieve optimal positioning without requiring complete structural redesign, thus managing complexity while enhancing versatility.
2Productivity
If manual CPR is performed, then the operation is simple, but adequate blood flow to essential organs cannot be achieved
Solution Approach 1:
The patent replaces manual mechanical CPR compression with an electromotor-driven plunger system. This substitution provides consistent, controlled compressive force that ensures adequate blood flow to essential organs, overcoming the limitations of manual CPR while maintaining operational simplicity through automated control.
Solution Approach 2:
The drive means with position measuring device enables automated control of the plunger compression cycles. The system self-regulates the compression rhythm and depth based on detected position feedback, eliminating the need for continuous manual intervention while ensuring optimal blood flow efficiency to vital organs.
3Manufacturing precision
If the holding device is not vertically adjustable, then the structure is simple, but proper positioning for different patient sizes cannot be achieved
Solution Approach 1:
The holding device incorporates vertically adjustable components that allow the drive means and plunger to be repositioned along the reanimation board. This dynamic adjustment capability enables adaptation to different patient sizes and treatment requirements while maintaining a relatively simple overall structure through standardized adjustment mechanisms.
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 apparatus enables effective and simple operation of CPR, ensuring efficient blood flow to vital organs by securely positioning the patient and accurately controlling the compressive massage, thereby enhancing survival chances in cardiac arrest situations.
Implementation Method 1
an electromotor (1) which is designed to drive the plunger (3)
Implementation Method 2
a position measuring device (25), with which the respective position of the plunger (3) during compressive massaging motion is detected
Implementation Method 3
the reanimation board (9), the cross-member (11) and the one or both pillars (7, 8), or the reanimation board (9) and the curved support (96), preferably form a force-locked or positive engagement structure, wherein the positive engagement can be produced with suitable locking and latching between the components of the structure. When compressive massage is performed with the plunger, the forces exerted are absorbed by the aforementioned structure.
