CPR Machine Camera for Patient Position Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current CPR chest compression machines face challenges in maintaining effective blood circulation due to potential shifts in the patient's body position, which can lead to ineffective compressions and reduced efficacy in preventing organ damage and death during medical emergencies.
Innovation Solution
A CPR machine equipped with a retention structure, compression mechanism, and integrated camera or ultrasound capabilities to monitor and adjust for patient position shifts, utilizing sight targets and imaging to ensure accurate and consistent compressions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If manual CPR is performed by trained rescuers, then CPR can be initiated quickly, but the quality of compressions degrades over time due to rescuer fatigue and stress
Solution Approach 1:
The CPR machine performs chest compressions autonomously without requiring continuous human intervention. The device self-regulates compression depth, rate, and quality while maintaining consistent performance throughout the resuscitation period, eliminating the degradation seen in manual CPR due to rescuer fatigue.
Solution Approach 2:
The patent replaces the manual mechanical system of human rescuers with an automated mechanical CPR device. This substitution ensures consistent, guideline-compliant compressions are delivered without the variability and fatigue inherent in human-performed manual CPR.
2Reliability
If CPR chest compression machines are used to maintain consistent compression quality, then compression reliability improves, but the patient's body position may shift during repeated compressions, reducing effectiveness
Solution Approach 1:
The CPR machine incorporates a camera system that continuously monitors the patient's body position and the location of sight targets. This visual feedback is processed by a controller that adjusts the compression mechanism in real-time to maintain accurate placement on the chest, compensating for any body shifts that occur during resuscitation.
Solution Approach 2:
The system transitions from a static compression approach to a dynamic one, where the compression mechanism continuously adapts its position and parameters based on real-time visual feedback from the camera system. This allows the machine to maintain optimal compression placement even as the patient's body position changes.
3Speed
If the chest is actively decompressed using suction cup lifting, then decompression speed improves, but the system complexity increases
Solution Approach 1:
The suction cup mechanism serves multiple functions: it provides active decompression by lifting the chest, maintains secure attachment of the compression device to the patient's body, and potentially aids in positioning. This multi-functionality justifies the added complexity by delivering multiple benefits from a single integrated component.

AI summary
A CPR chest compression machine includes a retention structure (140) configured to retain a patient's (182) body, and a compression mechanism (148) configured to perform automatically CPR compressions to the patient's (182) chest. The CPR machine also includes a camera (161) coupled to the retention structure (140) or to the compression mechanism (148). The camera (161) has a field of view (162) that spans at least a certain portion of the patient's (182) body, and is configured to acquire an image (407) of what is spanned by its field of view. The image (407) may be stored in a memory (130), displayed, transmitted, analyzed to diagnose the patient, detect shifting of the patient within the CPR machine, etc.
