Universal Defibrillation Electrode Pad for Adult and Pediatric Use
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing defibrillation electrode pad assemblies require multiple sizes for adult and pediatric subjects, leading to potential errors in positioning the electrodes and CPR administration area, which can result in suboptimal treatment during cardiac distress.
Innovation Solution
A universal defibrillation electrode pad with a mechanically coupled electrode section and CPR administration section, allowing for adjustable orientation between adult and pediatric settings, indicated by visual or tactile markers, enabling proper placement on subjects of different sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If differently sized defibrillation electrode pad assemblies are provided for pediatric and adult subjects, then proper positioning of electrodes and CPR administration area is achieved for each subject size, but device complexity and potential for selection errors increase
Solution Approach 1:
The electrode pad assembly is designed to serve both pediatric and adult subjects through a single universal configuration. The pad incorporates an electrode section and CPR administration section with dimensions and positioning that can properly accommodate both pediatric and adult anatomies when oriented correctly, eliminating the need for separate pediatric and adult pad sizes.
Solution Approach 2:
The pad assembly allows for rotational reorientation to adapt to different subject types. By rotating the pad 180 degrees, the relative positions of the electrode section and CPR administration section change, enabling proper positioning for either pediatric or adult subjects without requiring different pad designs.
2Device complexity
If a single universal defibrillation electrode pad is used for both pediatric and adult subjects, then device complexity is reduced and selection errors are minimized, but positioning accuracy may be compromised without proper orientation indicators
Solution Approach 1:
The pad incorporates visual indicators such as color-coded markings or symbols that change or differentiate based on the required orientation. These indicators guide the user to rotate the pad to the correct orientation for either pediatric or adult use, ensuring proper positioning accuracy while maintaining a single universal pad design.
Solution Approach 2:
The pad design incorporates asymmetric features including non-uniform placement of electrodes, CPR administration area, and orientation indicators. These asymmetric elements create a unique orientation that must be aligned correctly for proper function, preventing incorrect placement while allowing the same pad to serve both pediatric and adult subjects when oriented appropriately.
3Reliability
If the electrode section and CPR administration section are positioned for adult subjects, then proper treatment is achieved for adults, but the positioning is suboptimal for pediatric subjects
Solution Approach 1:
The relative positioning of the electrode section and CPR administration section is made dynamically adaptable through rotation. The pad can be oriented in two distinct configurations: one optimized for adult anatomy and another optimized for pediatric anatomy. This dynamic reorientation allows the same physical pad to provide reliable treatment for both subject sizes.
Solution Approach 2:
The pad design achieves universality by incorporating both adult-optimized and pediatric-optimized positioning within a single pad structure. Through proper orientation, the electrode section and CPR administration section are positioned to match the anatomical requirements of either adult or pediatric subjects, ensuring treatment efficacy across different age groups.

AI summary
A defibrillation electrode pad includes an electrode section and a CPR administration section. The electrode section and the CPR administration section are positioned in the defibrillation electrode pad relative to each other such that the CPR administration section is located above a sternum of an adult subject and the electrode section is located in a position appropriate for the administration of a defibrillation shock to the adult subject when the defibrillation electrode pad is oriented in a first orientation and such that the CPR administration section is located above a sternum of a pediatric subject and the electrode section is located in a position appropriate for the administration of a defibrillation shock to the pediatric subject when the defibrillation electrode pad is oriented in a second orientation different from the first orientation.
