Abstract:
A package in which a medical device is stored, the package comprising an outer shell providing a vapor barrier between an interior space inside the outer shell and an exterior environment, a medical device positioned in the interior space inside the outer shell, the medical device including a liquid-containing element that is subject to drying out as liquid from the liquid-containing element vaporizes and travels from the interior space to the external environment, a condition sensor comprising two metallic elements, each of the two metallic elements being 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:
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, a breakaway connection element positioned at the perimeter of the outer shell, one or more defibrillation electrodes positioned in the interior space inside the outer shell, a further electrical element positioned in the interior space inside the outer shell, electrical paths extending from the further electrical element through the breakaway element to the exterior environment, wherein the breakaway element and electrical paths are configured so that, when the outer shell is opened and the defibrillation electrodes are removed, the electrical paths are disconnected within the breakaway element.
Abstract:
Electrodes and circuitry for monitoring and stimulating the exterior of the human body, comprising delivering stimulation pulses to stimulation electrodes applied to the exterior of the body, detecting an electrical potential at monitoring electrodes applied to the exterior of the body, positioning at least a first and second monitoring electrode at locations at which an electrical artifact caused by the electrical stimulation pulses is substantially cancelled in a signal formed from the electrical potentials detected at the first and second monitoring electrodes.
