摘要:
A substantially rigid defibrillator carrying case having a hinged side, a latch disposed on a latch side opposite the hinged side, and a handle disposed on a handle side disposed between the hinged side and the latch side. The carrying case is constructed without protrusions and with a rigid handle, which combine to allow easy removal and deployment of the contents from a vehicle storage location to a cardiac arrest patient. The carrying case integrates a actuator to periodically test the operation of the defibrillator push buttons.

摘要:
A training adapter (28) for an automated external defibrillator (AED) (10) which provides for safe training use of any AED. The training adapter includes a circuit which ensures that any defibrillation voltage/current is shunted away from the trainee, training electrodes(26), and patient simulation equipment. The training adapter simultaneously provides to the AED a simulated patient ECG signal which causes the AED to operate as if an actual cardiac rescue were occurring, thus heightening the realism of the training experience.

摘要:
An electrotherapy apparatus includes a connecting mechanism coupled between an energy source and a pair of electrodes for contacting a patient. A controller coupled to the energy source configures the energy source to provide a selected one of a plurality of energy levels. The controller actuates the connecting mechanism to couple the energy source to the electrodes. A sensor coupled to the controller measures a parameter or parameters related to the energy delivered to the patient through the electrodes. The controller performs an operation using the output received from the sensor. Based upon the operation, the controller actuates the connecting mechanism to decouple the energy source from the electrodes. In an embodiment of the electrotherapy apparatus, the energy source includes a high voltage power supply for charging a capacitor to a selected one of a plurality of initial voltages. The sensor includes a voltage sensor to measure the voltage across the capacitor and a current sensor to measure the current supplied by the capacitor. The connecting mechanism includes electronic switches coupled between the capacitor and the electrodes to permit application of an electrotherapy waveform in either polarity. The controller performs the operation using the measured voltages and currents to control the electronic switches. The operation may include computing the patient impedance, determining a time constant of the voltage or current, determining a quantity of charge delivered to the patient, or determining the time required for the voltage or current to substantially equal a predetermined fraction of the voltage or current.

摘要:
An intelligent battery having an advance low battery warning for a battery powered device is provided. The intelligent battery comprises a battery suitable for powering a battery powered device and a charge monitor circuit. The charge monitor circuit continuously measures the amount of electrical charge input and output from the battery. When the amount of charge remaining in the battery goes below a threshold amount, an advance low battery warning is generated, wherein the charge remaining in the battery is calculated by subtracting the amount of electrical charge output from the battery from the amount of electrical charge input into the battery. The low battery warning occurs independently of the output voltage of the battery such that an advance low battery warning may be provided for a battery that maintains a substantially constant output voltage until just prior to complete discharge. The circuit also includes an imminent shutdown warning circuit that measures the output voltage of the battery, and provides a battery shutdown warning when the output voltage drops below a shutdown threshold voltage. In a preferred embodiment, the battery powered device is a defibrillator/monitor, and the threshold amount is equal to a selected percent of the battery's capacity plus sufficient charge to provide a selected number of charges to a defibrillator.
