Medical device configured to test for user responsiveness
First Claim
1. A wearable defibrillator configured to deliver therapy to a patient, the wearable defibrillator comprising:
- electrocardiogram sensing electrodes configured to sense an electrocardiogram signal of the patient wearing the wearable defibrillator;
therapy electrodes configured to provide a defibrillation treatment to the patient wearing the wearable defibrillator based on the sensed electrocardiogram signal;
a housing;
a response mechanism comprising a single response button or switch located on a portion of the housing and configured to be actuated by the patient in a predetermined sequence and within a certain time interval to generate a signal comprising an indication that the single response button or switch has been actuated in the predetermined sequence and within the certain time interval, the response mechanism comprising the single response button or switch are located on the housing so as to avoid accidental activation of the single response button or switch; and
at least one controller disposed within the housing and operatively connected to the electrocardiogram sensing electrodes, the therapy electrodes, and the single response button or switch, the at least one controller being configured todetect a cardiac arrhythmia based on the electrocardiogram signal of the patient wearing the wearable defibrillator,issue an alarm based on the detected cardiac arrhythmia,activate the defibrillation treatment via the therapy electrodes to the patient wearing the wearable defibrillator in response to expiration of a first time interval following the issuance of the alarm,receive the signal comprising the indication that the single response button or switch has been actuated in the predetermined sequence and within the certain time interval, andat least one of delay and withhold the defibrillation treatment to the patient wearing the wearable defibrillator in response to receiving the signal comprising the indication that the single response button or switch has been actuated in the predetermined sequence and within the certain time interval;
wherein the predetermined sequence comprisesa first movement by the patient of the single response button or switch from a first position to a second position anda second movement by the patient of the single response button or switch from the second position back to the first position within the certain time interval, the certain time interval being less than the first time interval.

Abstract
A medical device is disclosed that includes one or more treatment electrodes, one or more sensors, and one or more controllers connected to the one or more treatment electrodes and one or more sensors. The medical device also includes one or more response mechanisms connected to the one or more controllers. The one or more controllers are configured to receive input from the one or more response mechanism and are also configured to determine whether a patient wearing the medical device actuated the one or more response mechanisms based, at least in part, on the input received from the one or more response mechanisms. In some disclosed embodiments, the medical device is a wearable defibrillator.
