The invention provides, in some aspects, a coupler for inline connection of two bodies where one of the bodies provides linear motion to the other. Further aspects of the invention provide such a coupler comprising a first adapter linearly engaging a second adapter in a capture B. The first adapter defines a capture C for temporarily securing a first compatible body, and the second adapter defines a connector for securing a second compatible body. The capture B and the connector are oriented one to the other such that linear movement of the first compatible body translates into linear movement of the second compatible body. The capture B releases the secured compatible body upon pressing together of the first and second adapter. In a particular embodiment, a coupler of the type described above joins a compression module of a mechanical CPR device to a patient interface of that device.
The invention provides, in some aspects, an AMCPR method and apparatus that apply a continuous flex correction where a flex correction is determined based on one or more strokes, and applied to a subsequent compressive stroke. In these aspects, for example, the AMCPR's control system determines the flex correction to a future compressive stroke based on the rail voltage and amperage applied to a motor during a prior compressive stroke, such as an immediately prior stroke or such as the penultimate stroke. As a result of using the rail voltage and amperage applied to tire motor, the need for an additional sensor means, such as a force sensor, has been removed.

A charging circuit for a capacitor in a defibrillator includes a control enabling a setting of a desired time to charge a capacitor to a desired voltage in the defibrillator. The charging circuit further includes a flyback charge-pump circuit comprising a switch, an energy transfer transformer, an energy storage capacitor and a control. The switch is configured to stop or allow storage of energy in a transformer. The transformer transfers the energy to the capacitor. The flyback charge-pump circuit controls a duty-cycle on the switch so that a current draw from a power source (e.g. battery) is sufficient to enable charging the capacitor to the desired voltage within the desired time set on the control.

The connector between the patient electrode pads and the base unit of an automatic external defibrillator (AED) system can be formed by capturing a printed circuit board (PCB) within a connector housing. The PCB can have conductive metal traces that serve as the contact points between the wires from the patient electrodes and the electronics within the AED base unit. The PCB in combination with the conductive metal traces can be shaped similar to a conventional two-prong or two-blade connector. Employing such a PCB-based connector may result in AED pads which are less complex and less costly to manufacture. The PCB can also support a configuration circuit that is positioned between the conductive metal traces and that allows the AED to read and store information about the attached pads. For example, the AED can use this data storage feature to check the expiration date of the pads.

A semi-automated AED with a second shock switch. In an illustrative embodiment, programming running on the AED after prompting a user of the AED to push a shock switch looks to see if an event associated with pushing the shock switch, such as the delivery of a shock, has occurred. If the event being monitored for has not occurred within a given time, the user is prompted to push another button to initiate the event.
External portable medical devices, such as portable external defibrillators (PEDs), have long standby times and may be required to indicate their operational status to a user while conserving battery power. Frequently, numerous PEDs are scattered throughout one or more large facility, which may make identifying a PED that is indicating an operational status that requires attention more difficult. To conserve power and provide more effective notice, a PED may use a broadcast transmitter, which minimizes power usage, to communicate the PED's status to a remote monitor that is connected to a relatively unlimited power supply. The remote monitor may then provide a wide variety of sensory alerts to indicate the status of the PED without concern for the power consumption associated with the sensory alert.
Battery powered systems with long standby times, such as automatic external defibrillators (AEDs), may be required to indicate their operational status to a user by blinking lights or sounding speakers or buzzers. These active status indication activities consume power thereby reducing the battery life of the system. To conserve power and to be more effective in seeking attention from a human operator, the status alerts for the AED produced by an active status indicator (ASI) system can be more meaningful to humans or more unique relative to status alerts provided by conventional devices. Additionally, the ASI system may automatically adjust power consumed by the indicators in response to sensing environmental conditions of the AED.

The PCB can also support a configuration circuit that is positioned between the conductive metal traces and that allows the AED to read and store information about the attached pads. For example, the AED can use this data storage feature to check the expiration date of the pads.
A video display coupled to an automatic external defibrillator (AED) and capable of full-motion video can support added functionality of the AED. One advantage of the video display is that it can be used to present standby status information of the AED quickly to an AED operator while the AED is in a low power standby mode or non-operative state. The video display may present status information in response to touching the display or activating a button while the AED is in a non-operative state. When the AED is in an operative state, such as during a rescue, the display may comprise a graphical user interface that may be navigated using touch-screen technology or buttons built into the AED. During a rescue, the video display may present live or stored electrocardiograms (ECGs) and instructions for operating the AED.

Battery powered systems with long standby times, such as automatic external defibrillators, may be required to indicate their operational status to a user by blinking lights or sounding speakers or buzzers. These active status indication activities consume power thereby reducing the battery life of the system. Automatically adjusting the level and frequency of these indication activities to match the ambient environment can reduce power consumption of the battery operated system. For example, in a dimly lit room, an indicator light may be visible even though it might be too dim to be seen in a bright room. Thus, if the room is dim, indicator lights can be dimmed to conserve power. These automatic adjustments made in response to the environment may help conserve power and extend battery life.
