Benefits of technology

The present invention is a defibrillator for delivering defibrillation energy to a patient. The defibrillator includes a controller that monitors patient information and uses it to control the delivery of defibrillation energy to the patient. This allows for more effective treatment of cardiac arrhythmias. The invention also includes a variety of techniques for increasing the wear of the electrodes without causing skin irritation or damage. Additionally, the invention includes a memory that stores patient information and an external interface for transmitting and analyzing the patient information. These features make the defibrillator more efficient and effective in treating cardiac arrhythmias.

Problems solved by technology

Also, the size, configuration, and materials used to construct the electrodes contribute the amount of time that the electrodes can be worn by a patient.

Embodiment Construction

[0062] The present invention is directed to a defibrillation system for use in treating patients who have suffered from cardiac arrhythmias. A representative embodiment of the invention is shown in FIGS. 1 and 2. As shown in these figures, defibrillation system 1 is comprised of base station 2, electrode harness 4, personal computer 6, patient simulator 7, central repository 9, and wearable defibrillator 10. A brief overview of the operation of each of these components is provided below, followed by detailed descriptions thereof.

[0063] Defibrillator 10 is capable of interfacing either to base station 2, as shown in FIG. 1, or to electrode harness 4, as shown in FIG. 2. To this end, both electrode harness 4 and base station 2 include physical connector identifiers at their respective interfaces to defibrillator 10. By reading these connector identifiers, defibrillator 10 is able to determine both the type of interfaced device (i.e., a base station or electrode harness) and the ident...

Abstract

A method of treating a patient for ventricular tachycardia using a wearable defibrillator includes monitoring the patient for a predetermined condition via one or more electrodes on the defibrillator, sending a message to the patient in response to the predetermined condition, activating the defibrillator so that the defibrillator delivers defibrillation energy to the patient, and storing at least one of the results of the monitoring, sending and activating steps in a memory on the defibrillator. The method also includes downloading information stored in the memory of the defibrillator to a base station having an external interface, and transmitting the information downloaded from the memory of the base station to an external location via the external interface of the base station.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention is directed to a defibrillation device, and more particularly to a personal wearable pacer / cardioverter / defibrillator which monitors a patient's condition, detects shockable or paceable arrhythmias, determines consciousness, and, in the case that the patient is determined to be unconscious, administers therapy to the patient. [0003] 2. Description of the Related Art [0004] Cardiac arrhythmias, such as ventricular fibrillation and ventricular tachycardia, are electrical malfunctions of the heart, in which regular electrical impulses in the heart are replaced by irregular, rapid impulses. These irregular, rapid impulses can cause the heart to stop normal contractions, thereby interrupting blood flow therethrough. Such an interruption in blood flow can cause organ damage or even death. [0005] Normal heart contractions, and thus normal blood flow, can be restored to a patient through application of...
