Abstract:
A defibrillator and an electrode package combination comprising a storage element, processing circuitry, and a user interface contained in a housing. The housing has a first mechanical element or elements on the exterior of the housing and configured so that an electrode package can be mechanically attached to the exterior of the housing substantially in full view on the exterior. The package comprising an outer shell, two or more defibrillation electrodes sealed inside the electrode package, a portion of the outer shell configured to be opened to remove the electrodes, and a second mechanical element or elements on the exterior of the outer shell and configured to mate with the first mechanical element on the housing of the defibrillator to mechanically attach the package to the housing.
Abstract:
An electrode package for use with a defibrillator, the electrode package comprising an outer shell providing a vapor barrier between an interior space inside the outer shell and an exterior environment, one or more defibrillation electrodes positioned in the interior space inside the outer shell, each of the defibrillation electrodes including a metallic layer (42) in electrical contact with a conductive liquid-containing layer (40) through which electrical current is delivered to a patient when the defibrillation electrodes have been applied to the patient, the conductive liquid-containing layer (40) being subject to drying out as liquid from the water-containing layer vaporizes and travels from the interior space to the external environment, and one or more electrical conductors extending from inside of the outer shell to a package electrical connector outside of the shell, the package electrical connector connected to the defibrillator, and an electronic memory device positioned outside the outer shell and in electrical contact with some of the electrical conductors extending from the outer shell to the package electrical connector
Abstract:
A package in which a medical device is stored, comprising an outer shell, a medical device positioned in the interior space inside the outer shell, a condition sensor comprising two metallic elements, each of which is composed of different metals, with each of the different metals selected so that the two metallic elements form an anode and a cathode of an electrochemical cell, each of the two metallic elements being in electrical contact with a conductive water-containing element, so that the water-containing element forms the electrolyte of the electrochemical cell, and an electrically conductive path extending from each of the metallic elements to a location wherein the electrochemical potential formed between the metallic elements can be measured to provide an indication of the degree to which the conductive water-containing element has dried out.
Abstract:
A defibrillation electrode for application to the front of the chest of a patient, the electrode comprising a metallic layer, a conductive liquid-containing layer in contact with the metallic layer and configured to contact the skin of the patient, an adhesive layer surrounding the conductive liquid-containing layer and having a layer of adhesive configured to adhere the electrode to the patient, a release layer configured to be removed from the electrode prior to application to the patient, the release layer being in contact with the adhesive and the conductive liquid-containing layer prior to removal, wherein the electrode has a lateral perimeter at or laterally outside of the adhesive layer, and wherein the lateral perimeter is generally triangular.

Abstract:
A medical device such as a defibrillator that incorporates corrective voice prompts that navigate users around operator errors. The voice prompts may, for example, address errors of readiness (e.g., failing to connect the defibrillator to an AC power source, failing to pre-connect electrodes, etc.), errors of omission (i.e., forgetting to do something, such as attempting to deliver a shock before the defibrillator is charged), and errors of commission (i.e., doing the wrong thing, such as attempting to shock VF when in the synchronization mode). The voice prompts may address errors in the delivery of therapy (e.g., attempting to shock VF when in the synchronization mode) or they may address errors other than in the delivery of therapy (e.g., failing to connect to an AC power source).
Abstract:
A device (10) for assisting a rescuer in delivering therapy to an adult or pediatric patient, the device including a user interface (21) comprising a display (23) and/or audio speakers (24), the user interface (21) being configured to deliver prompts to a rescuer to assist the rescuer in delivering therapy to a patient; a processor (20) configured to provide prompts to the user interface (21) and to perform an ECG analysis algorithm on ECG information detected from the patient; at least one detection element (253) configured to determine without rescuer input via the user interface that a pediatric patient is being treated; wherein, if a pediatric patient is detected, the processor modifies the ECG analysis algorithm or the prompts provided to the user interface to use an ECG analysis algorithm or prompts adapted for a pediatric patient rather than for an adult patient.
