Abstract
In embodiments, a wearable medical system (WMS) for an ambulatory patient, which can be a wearable cardioverter defibrillator (WCD) system, analyzes the patient's ECG signal to generate a detection outcome. The WMS also has an ambulatory user interface that outputs a human-visible indication. A programming device, such as a PC, a tablet, etc., establishes a communication link with the WMS during an in-person session with the patient. The programming device may include a programming screen that reproduces the human-visible indication in real time. An advantage can be that the person programming the WMS need not strain to look also at the ambulatory user interface at the time they are looking at the programming device. Another advantage can be that the patient will recognize that he or she is better protected, and have their confidence in the WMS increased, and therefore better comply with wearing the WMS as required.
Core Innovation
The invention relates to a wearable cardioverter defibrillator (WCD) system configured to be worn by an ambulatory patient and includes electrodes coupled to a support structure to sense an electrocardiogram (ECG) signal. An ambulatory processor analyzes the sensed ECG signal to generate a detection outcome, and the defibrillator is configured to discharge an electrical charge through the patient via at least some of the electrodes responsive to the detection outcome while the support structure is worn.
The WCD system further includes an ambulatory user interface coupled to the support structure and the defibrillator, where the ambulatory user interface outputs a human-visible indication that includes a light source configured to be turned on and then off according to a certain pattern. The ambulatory user interface is therefore configured to output the human-visible indication as the patient indication.
A separate programming device, distinct from the defibrillator and operable while not coupled to the support structure, receives defibrillator data over a local communication link shorter than 99 feet. The programming device displays a diagnostic image about the human-visible indication responsive to the received defibrillator data by depicting the light source and its turning on and off according to the certain pattern.
Claims Coverage
The provided portion includes two independent claims, one system claim and one method claim. Across the independent claims, the core inventive coverage includes a wearable defibrillator with ambulatory ECG analysis and shock delivery, a light-source human-visible indication, and a separate programming device that receives indication-related defibrillator data over a local communication link shorter than 99 feet and displays a diagnostic image depicting the light source pattern.
Wearable defibrillator with ambulatory detection outcome and shock discharge
A defibrillator includes an ambulatory processor configured to analyze the sensed ECG signal so as to generate a detection outcome from the sensed ECG signal, and is configured to discharge, through the patient via at least some of the electrodes, an electrical charge responsive to the detection outcome while the support structure is worn by the patient.
Ambulatory light-source human-visible indication with on/off pattern
An ambulatory user interface configured to output a human-visible indication and to include a light source configured to be turned on to output the human-visible indication and then off, where the light source is turned on and off according to a certain pattern.
Local communication link under 99 feet transmitting defibrillator data related to indication
An ambulatory communication module configured to transmit defibrillator data over a local communication link shorter than 99 feet in length, where the defibrillator data is related to the human-visible indication.
Separate programming device reproducing indication as diagnostic image depicting the light source
A programming device distinct from the defibrillator and operable while not coupled to the support structure, comprising a programming communication module configured to receive the transmitted defibrillator data over the local communication link, a programming user interface that includes a programming screen arranged for viewing by a person other than the patient, and a programming processor configured to cause the programming screen to display a diagnostic image about the human-visible indication responsive to the received defibrillator data by depicting the light source, where the diagnostic image further depicts the light source turning on and off according to the certain pattern.
Method sensing ECG, analyzing detection outcome, and transmitting indication-related defibrillator data
The method comprising sensing, via at least some of the electrodes, an electrocardiogram (ECG) signal of the patient; analyzing, by the ambulatory processor, the sensed ECG signal so as to generate a detection outcome from the sensed ECG signal; and transmitting, by the ambulatory communication module, defibrillator data over a local communication link shorter than 99 feet in length, where the defibrillator data is related to the human-visible indication.
Method outputting light-source indication and displaying diagnostic image depicting light source pattern
Outputting, by the ambulatory user interface, a human-visible indication where the ambulatory user interface includes a light source configured to be turned on to output the human-visible indication and then off; receiving, by the programming communication module over the local communication link, the transmitted defibrillator data; and displaying, by the programming screen, a diagnostic image about the human-visible indication responsive to the received defibrillator data by depicting the light source.
Across the independent claims, the coverage focuses on a wearable defibrillator system that generates a detection outcome from sensed ECG and drives a light-source human-visible indication in an on/off pattern, while a separate programming device receives indication-related defibrillator data over a local link shorter than 99 feet and displays a diagnostic image depicting the light source and its on/off pattern for viewing by a person other than the patient.
