Filed:

Apr 8, 1998

Appl. No.:

09/057030

Inventors:

Kenneth F. Olson - Edina MN
William S. Parker - Maple Grove MN

Assignee:

SurVivaLink Corporation - Minnetonka MN

International Classification:

A61N 118

US Classification:

607 5, 607 29

Abstract:

A defibrillator battery includes at least one battery cell, a housing surrounding the at least one battery cell, and a memory connected to the at least one battery cell. The memory can be positioned inside of the housing that surrounds the at least one battery cell. The defibrillator battery can be used with a defibrillator including a battery status indicator which communicates with the defibrillator battery to indicate the status of the defibrillator battery. In a method of determining defibrillator battery status using the defibrillator battery and associated battery status indicator enables an operator to always determine the remaining charge of the battery and to determine when to replace the battery. The defibrillator battery, and associated battery status indicator, insures constant readiness of an automated external defibrillator for defibrillating a patient by preventing defibrillator failure due to an unknown reduced battery charge.

International Classification:

A61N 139

US Classification:

607 5

Abstract:

An apparatus and method for determining an optimal transchest external defibrillation waveform that provides for variable energy in the first or second phase of a biphasic waveform that, when applied through a plurality of electrodes positioned on a patients torso, will produce a desired response in the patients cardiac cell membranes. The method includes the steps of providing a quantitative model of a defibrillator circuit for producing external defibrillation waveforms, the quantitative model of a patient includes a chest component, a heart component, a cell membrane component and a quantitative description of the desired cardiac membrane response function. Finally, a quantitative description of a transchest external defibrillation waveform that will produce the desired cardiac membrane response function is computed. The computation is made as a function of the desired cardiac membrane response function, the patient model and the defibrillator circuit model.

International Classification:

A61N 139

US Classification:

607 5, 607 59, 600522

Abstract:

An automated external defibrillator (AED) includes the ability to store rescue information. The AED has a case for housing a power supply that is electrically connected to a circuit for generating a defibrillation pulse. The circuit is electrically connected to a pair of electrodes that are applied to a patient to deliver the defibrillation pulse. The AED further comprises an archival storage means for storing rescue information. The archival storage means is containable within the case and is able to store various types of rescue information including patient data, operational data of the AED, and sound that occurs within the immediate vicinity of the AED during a rescue.

International Classification:

A61N 1/365

US Classification:

607 5

Abstract:

A defibrillator enclosure system generally includes an automated external defibrillator (AED), an openable cabinet, a detector, and an alarm circuit. The openable cabinet is used to enclose the AED while the detector monitors the presence and absence of the AED within the cabinet. Specifically, upon detecting that the AED is no longer within the cabinet, the detector activates an alarm circuit whereby an alarm indicating the absence of the AED is issued.

Assignee:

SurVivaLink Corporation - Minneapolis MN

International Classification:

A61N 139

US Classification:

607 5

Abstract:

An external defibillator including an operator interface and a high voltage circuit responsive to a controller for producing monophasic waveform defibrillation pulses and/or biphasic waveform defibrillation pulses. The controller can implement a biphasic waveform test protocol by causing the high voltage circuit to sequentially generate one or more biphasic waveform defibrillation pulses before generating monophasic waveform defibrillation pulses in response to sequential actuations of the operator interface during a patient rescue.
