Abstract
Example defibrillator electrode assemblies compression assemblies are described that may be dimensioned and configured for use on a patient despite physical constraints that limit the area or locations on a patient onto which an electrode assembly may be placed. A cardio pulmonary resuscitation (CPR) assembly is also described that protects a patient with a transthoracic incision from further injury during application of CPR compressions proximate to the incision.
Core Innovation
The invention provides a medical assembly for use in providing resuscitative treatment to a patient. The assembly includes three therapy pads, each having a non-conductive substrate and an electrically conductive layer in contact with the non-conductive substrate, and a chest compression sensor removably attached to a top surface of at least one of the therapy pads, where the bottom surface is arranged to contact skin when in use.
A controller is coupled to each of the therapy pads and is configured to initiate application of a first defibrillation current between the respective electrically conductive layers of at least two therapy pads such that a first vector of current travel occurs between the at least two therapy pads. The controller is also configured to initiate a second defibrillation current between the respective electrically conductive layers of two or more therapy pads such that a second vector of current travel different from the first vector of current travel occurs between the two or more therapy pads.
The disclosed configuration and structure include configurable electrode assemblies and chest compression sensor assemblies intended for patients with limited thoracic placement area and for patients with transthoracic or surgical incisions. The therapy pads are described as including separable patterns or boundaries that enable reconfiguration into different sizes or shapes, including high aspect ratio electrodes, to fit around other devices and avoid sensitive regions, while using low-peel-strength adhering materials to reduce re-opening or injury of sensitive tissue.
The chest compression sensor is described as being stored in a sterile pouch for placement within a sterile field, and the sensor modalities include inertial measurement sensors using an accelerometer and optionally a gyroscope for rate, depth, and orientation. A chest compression assembly is described as distributing force over opposing sides of an incision and/or raising or protecting a sensitive region to mitigate further injury during manual CPR compressions.
Claims Coverage
The independent claim defines a medical assembly with three therapy pads and a chest compression sensor removably attached to a pad, where a controller initiates defibrillation currents between selected pad pairs to create different current vectors. The inventive features are centered on removable sensor attachment and controller-driven current vector changes using conductive layers on different therapy pads.
Three therapy pads with conductive layers and removably attached chest compression sensor
A medical assembly includes first, second, and third therapy pads each having a non-conductive substrate and an electrically conductive layer, with a chest compression sensor removably attached to a top surface of at least one therapy pad opposite from a bottom surface arranged to contact skin when in use.
Controller configured to initiate defibrillation currents to create different current vectors
A controller coupled to each of the therapy pads initiates a first defibrillation current between the electrically conductive layers of at least two therapy pads such that a first vector of current travel occurs between the at least two therapy pads, and initiates a second defibrillation current between the electrically conductive layers of two or more therapy pads such that a second vector of current travel different from the first vector occurs between the two or more therapy pads.
Overall, the claimed coverage focuses on pairing a chest compression sensor removably attached to a multi-pad defibrillation electrode assembly with controller-initiated defibrillation currents applied between different combinations of therapy pads to produce different current vectors.
