Inflatable Lateral Support Pads for CPR Chest Compression Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mechanical CPR devices lack the ability to provide consistent and stable chest compressions for patients with varying chest sizes, and they often require manual adjustment during transport, which can disrupt the continuity of CPR procedures.
Innovation Solution
The design incorporates inflatable or foam support pads that can be affixed or removably attached to a mechanical CPR device, providing lateral support and stability to the patient's chest, allowing for adjustable positioning and use on patients of different chest widths, and enabling the device to be tilted during transport without compromising CPR quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mechanical CPR devices are used to provide consistent compressions, then compression consistency is improved, but the device cannot accommodate patients with varying chest sizes
Solution Approach 1:
The support pad is made inflatable with adjustable volume, allowing the device to dynamically adapt to different patient chest sizes while maintaining consistent compression force. The inflatable chambers can be adjusted to match the specific chest width and depth of each patient.
Solution Approach 2:
The physical parameters of the support pad (volume, pressure, height) are changed through inflation/deflation mechanisms to accommodate varying chest dimensions. This allows the same device to maintain proper compression geometry across different patient sizes.
2Adaptability or versatility
If manual adjustment is performed during transport, then adaptability to different positions is improved, but CPR continuity is disrupted
Solution Approach 1:
The support pad is pre-configured with adjustable inflatable chambers that can be quickly modified during transport without interrupting CPR. The device allows preliminary positioning adjustments before compression begins, maintaining continuity.
Solution Approach 2:
The device includes self-adjusting mechanisms that allow rapid repositioning during transport without requiring manual intervention that would disrupt CPR. The inflatable support pad can be quickly adjusted to maintain proper alignment during movement.
3Device complexity
If fixed support structure is used, then device simplicity is improved, but positioning accuracy for different patients deteriorates
Solution Approach 1:
The support structure transitions from fixed to dynamic through inflatable chambers that can be adjusted to match different patient anatomies. This maintains positioning accuracy while adding minimal complexity through the inflation/deflation mechanism.
