Adaptive CPR Support with Dynamic Tilt and Sensor Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for cardiopulmonary resuscitation (CPR) lack effective means to optimize blood circulation and cerebral perfusion, particularly in emergency settings where timely re-establishment of systemic blood flow is critical for patient survival.
Innovation Solution
A patient support structure with adjustable tilt angles, integrated with a chest compression device, utilizes sensors and processors to determine optimal tilt positions based on physiological parameters and phases of CPR, enhancing blood circulation and cerebral perfusion by aligning anatomical references for precise chest compression application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual CPR chest compressions are performed, then some blood circulation is maintained, but the effectiveness is insufficient and operator fatigue reduces quality over time
Solution Approach 1:
The CC device is configured to perform chest compressions autonomously without requiring continuous manual operation by care providers. The device self-regulates compression depth, rate, and timing based on sensor feedback, eliminating operator fatigue and maintaining consistent compression quality throughout the CPR treatment period.
Solution Approach 2:
The patent replaces the manual mechanical compression system with an automated mechanical system. The CC device uses motors, sensors, and control algorithms to substitute human operators, providing more precise and reliable chest compressions with consistent force and timing.
2Productivity
If patient position is fixed during CPR, then setup is simple, but blood circulation and cerebral perfusion are not optimized
Solution Approach 1:
The patient support structure transitions from a static fixed position to a dynamic adjustable position. The tilt angle can be changed during CPR treatment to optimize blood circulation and cerebral perfusion based on patient response and treatment phase, making the system adaptive rather than fixed.
Solution Approach 2:
The patent changes the positional parameter of the patient support structure by adjusting the tilt angle. This parameter modification optimizes hemodynamic outcomes during CPR without requiring complete structural redesign, balancing complexity with performance improvement.
3Loss of time
If tilt angle is manually adjusted, then equipment complexity is reduced, but response time to optimize circulation is delayed
Solution Approach 1:
The tilt adjuster system incorporates sensors that monitor patient physiological parameters and provide feedback to the control system. This feedback loop enables automatic real-time adjustment of the tilt angle to optimize blood circulation and cerebral perfusion, reducing the time delay associated with manual adjustment.
Solution Approach 2:
The manual tilt adjustment mechanism is replaced with an automated motorized system controlled by a processor. This substitution eliminates the time delay of manual operation and enables rapid response to changing patient conditions during CPR treatment.
4Measurement precision
If chest compression device position is not adjustable, then device simplicity is maintained, but alignment with anatomical reference points is imprecise
Solution Approach 1:
The CC device mount provides adjustable positioning to achieve precise local alignment with the patient's anatomical reference points (sternum). This localized precision in compression placement improves treatment effectiveness without requiring adjustment of the entire device structure.

AI summary
A patient support structure for assisting cardiopulmonary resuscitation (CPR) treatment of a patient is described. The patient support structure includes a base frame, one or more patient support sections supported by the base frame, at least one tilt adjuster coupled to at least one of the patient support sections and configured to tilt the at least one of the patient support sections, around a transverse axis of the patient support structure, to a tilt angle, and a chest compression (CC) device mount disposed on at least one of the patient support sections and configured to adjustably secure a CC device to the patient support structure. The tilt angle may be a target tilt angle and the patient support structure may further include a processor configured to determine the target tilt angle based on at least one of sensor input and user input.
