Wedge-Shaped CPR Support Base with Swivel Head for Single-Operator Resuscitation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cardio-pulmonary resuscitation devices require multiple medical practitioners to perform chest compressions and oxygen therapy, leading to delays and inefficiencies in emergency situations, particularly when only one practitioner is available, and do not allow for proper airway opening or quick patient positioning.
Innovation Solution
A device with a wedge-shaped support base and swivel head support that allows a single practitioner to perform continuous chest compressions and oxygen therapy by enabling correct airway opening and hyperextension of the patient's neck, using flexible polymer springs and adjustable ventilation mask holders.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple medical practitioners are used to perform chest compressions and oxygen therapy, then the quality of resuscitation care is improved, but the response time is delayed and the complexity of operation increases
Solution Approach 1:
The device merges the functions of airway management (head positioning) and oxygen delivery into a single integrated system. The head support with adjustable positioning allows one practitioner to simultaneously manage airway patency and administer oxygen therapy through the integrated mask holder, eliminating the need for multiple practitioners while maintaining care quality and reducing response time.
Solution Approach 2:
The head support structure serves multiple functions: it positions the patient's head for airway opening, supports the oxygen mask, and provides structural framework for the entire resuscitation device. This multi-functionality allows a single practitioner to perform all necessary tasks without requiring additional personnel.
2Reliability
If multiple medical practitioners are required for airway management and oxygen therapy, then proper airway opening is achieved, but the device complexity and operational difficulty increase
Solution Approach 1:
The device combines head positioning mechanisms and oxygen mask support into a single integrated structure. The adjustable head support simultaneously achieves proper airway alignment and provides a stable platform for mask application, allowing one practitioner to manage both functions without requiring complex separate systems or multiple operators.
Solution Approach 2:
The head support features adjustable and movable components that allow dynamic adaptation to different patient anatomies. The positioning mechanisms can be quickly adjusted by a single practitioner to achieve optimal airway alignment, providing the effectiveness of multiple practitioners with simplified operation.
3Reliability
If traditional resuscitation devices are used requiring multiple practitioners, then oxygen therapy is provided, but continuous oxygen supply during chest compressions cannot be maintained
Solution Approach 1:
The integrated head support and mask holder design allows the oxygen mask to remain securely positioned on the patient's face throughout continuous chest compressions. The stable structural support prevents mask displacement, ensuring uninterrupted oxygen flow and maintaining continuous therapeutic action without requiring practitioners to adjust or reposition equipment during compressions.
4Reliability
If known resuscitation devices are used, then ventilation support is provided, but quick patient repositioning for vomiting is not enabled
Solution Approach 1:
The device is designed with modular components including the head support, mask holder, and positioning mechanisms that can be quickly adjusted or reconfigured. This segmentation allows rapid repositioning of the patient's head and body when vomiting occurs, while maintaining ventilation support through the integrated oxygen delivery system.

AI summary
A device for cardio-pulmonary resuscitation of a patient includes a support base, a swivel support, a mask holder and two lateral support elements. The support base is wedge-shaped in order to support the patient. There are guiding means and swivel elements provided in the support base and in the swivel support. The device makes it possible to adjust the position of the mask holder both vertically and horizontally to adapt to the dimensions of the user via a plurality of toothed elements. The configuration allows the combination with any existing continuous ventilation equipment.
