Integrated ECG and Defibrillation Applicator for Active Compression-Decompression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cardiac resuscitation systems face challenges in efficiently integrating chest compressions with defibrillation treatments, leading to delays and interruptions in acute care due to the need to switch between devices for monitoring and administering ECG signals and defibrillation shocks.
Innovation Solution
A medical apparatus that combines an electrocardiogram (ECG) input, defibrillation output, and an applicator body for active compression-decompression therapy, allowing for simultaneous monitoring of ECG signals and administration of defibrillation shocks during chest compressions, minimizing pauses and optimizing blood circulation and ventilation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If separate devices are used for ECG monitoring and defibrillation treatment, then device functionality is specialized, but treatment time is increased due to switching between devices
Solution Approach 1:
The patent combines ECG monitoring, defibrillation treatment, and active compression-decompression therapy into a single integrated medical apparatus. The applicator body houses both the ECG input for monitoring and the defibrillation output for treatment, allowing simultaneous or sequential operations without device switching. This merging eliminates treatment delays while maintaining specialized functionality for each therapeutic modality.
Solution Approach 2:
The medical apparatus is designed with multi-functionality, where a single device performs multiple functions: ECG signal monitoring, defibrillation shock delivery, and active compression-decompression chest therapy. The applicator body serves as a universal platform that can deliver different therapeutic interventions through integrated components, reducing the need for multiple separate devices and minimizing interruptions in acute care.
2Productivity
If device switching is required for ECG monitoring and defibrillation, then operational simplicity is maintained, but treatment continuity is interrupted
Solution Approach 1:
The patent merges ECG monitoring and defibrillation operations into a single integrated apparatus. The applicator body contains both the ECG input for continuous monitoring and the defibrillation output for shock delivery, allowing rescuers to perform both functions without switching devices. This integration maintains ease of operation by providing a unified control interface while dramatically improving treatment efficiency through continuous, uninterrupted care.
3Reliability
If conventional chest compressions are used, then device simplicity is maintained, but blood flow enhancement is insufficient compared to active compression-decompression
Solution Approach 1:
The patent implements active compression-decompression therapy using a dynamic mechanism that alternates between compressing and actively decompressing the patient's chest. The applicator body incorporates a coupling surface that adheres to the chest and a mechanical system that performs both downward compression strokes and upward decompression strokes. This dynamic active decompression phase enhances venous refilling of the heart and improves blood flow compared to conventional static compressions, while the mechanism remains integrated within the single apparatus.

AI summary
A medical apparatus provides resuscitative therapy to a patient. The apparatus includes an electrocardiogram (ECG) input, a defibrillation output configured to provide an electrical defibrillation shock treatment, and an applicator body configured to provide active compression decompression therapy to the patient's chest. The applicator body includes a rescuer end configured for hands of the rescuer to press and pull on the applicator body, a coupling surface configured to adhere to the patient's chest to provide active compression decompression therapy, a capacitor, and processor(s) configured to receive and analyze the ECG signal of the patient, determine whether the patient is in need of defibrillation, and administer the defibrillation shock treatment to the patient.
