Adhesive Pad Suction Cup CPR Device Adherence
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current CPR methods face challenges in optimizing chest compressions and decompressions, particularly in maintaining adherence of active compression decompression devices to the patient's chest, which affects the effectiveness of blood circulation and ventilation during cardiopulmonary resuscitation.
Innovation Solution
The system employs an adhesive pad with a gel-like material and a coupling surface that complements a suction cup, along with a sensor and a mechanical attachment mechanism, to ensure secure adherence of the active compression decompression device to the patient's chest, allowing for controlled and efficient compression and decompression phases.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an active compression decompression device is used to improve blood circulation and ventilation, then CPR effectiveness is improved, but device adherence to the patient's chest deteriorates
Solution Approach 1:
The landing pad is constructed as a composite structure combining a rigid base layer for structural support, a gel layer for conformability and seal formation, and an adhesive layer for secure attachment. This multi-material composition allows the device to simultaneously maintain structural integrity for force transmission and adaptability for stable adherence to the chest surface during compression-decompression cycles.
Solution Approach 2:
The gel layer's viscoelastic properties enable it to change its physical parameters dynamically - becoming more compliant during device attachment to form a seal, and providing stable support during compression phases. The material's ability to adjust its mechanical properties in response to applied forces resolves the contradiction between needing rigidity for force transmission and flexibility for adherence.
2Stability of the object's composition
If a suction cup coupling mechanism is used to maintain device adherence, then attachment stability is improved, but device complexity increases
Solution Approach 1:
The suction cup coupling mechanism utilizes pneumatic principles to create a vacuum seal between the device and the landing pad. By employing atmospheric pressure differential rather than mechanical fasteners or adhesives alone, the system achieves stable attachment with relatively simple component structure. The suction cups conform to the curved surface of the applicator body, providing secure attachment during dynamic CPR movements.
3Stability of the object's composition
If a gel-like material is used to form a seal, then adherence consistency is improved, but manufacturing complexity increases
Solution Approach 1:
The gel layer functions as a flexible sealing film that conforms to irregularities in both the chest surface and the device interface. This thin, compliant layer compensates for manufacturing tolerances and surface imperfections, ensuring consistent seal formation without requiring high-precision manufacturing. The gel's flowability during application allows it to self-level and fill gaps, simplifying the manufacturing process while maintaining adherence consistency.

AI summary
Systems and apparatuses related to the field of cardiac resuscitation, and in particular to devices for assisting rescuers in the administration of cardio-pulmonary resuscitation (CPR) are described herein. The system includes an adhesive pad configured to be adhered to at least a portion of a patient's chest, a sensor configured to be placed on the patient's chest and to measure at least one chest compression parameter during CPR treatment, and a landing pad having a coupling surface at least partially surrounding the sensor and configured for maintaining adherence with an active compression decompression device, the adherence sufficient to transfer decompression force between the active compression decompression device and the patient's chest during the CPR treatment.
