Wearable cardioverter defibrillator (WCD) system having WCD mode and also AED mode
In embodiments, a Wearable Cardioverter Defibrillator (WCD) system includes a support structure for the patient to wear, and components that the support structure maintains on the patient's body. The components include a defibrillator, associated electrodes, and so on. The defibrillator can operate in a WCD mode while the patient wears the support structure. The defibrillator can further operate in a different, AED mode, during which time the patient need not wear a portion of the support structure, or even the entire support structure. Sometimes the AED mode is a type of a fully automatic AED mode. Other times the AED mode is a type of a semi-automated AED mode, where an attendant is present to administer the shock; at such times, the patient may not even need to have electrodes attached. This way the patient is more comfortable for a longer time.
1. A wearable cardioverter defibrillator (WCD) system for an ambulatory patient, comprising:
a support structure configured to be worn by the ambulatory patient;
a defibrillator configured to be coupled to the support structure; and
a defibrillation electrode, including:
a wire lead that is configured to be coupled to the defibrillator,
a pad having two functional sides comprising a first functional side and a second functional side, and coupled to the wire lead, the pad configured to be coupled to the support structure so that the first functional side of the pad is maintained on a body of the ambulatory patient when the support structure is worn by the ambulatory patient, and
an adhesive material arranged on the second functional side of the pad so that the adhesive material is shielded from contacting the support structure or the body of the ambulatory patient when the first functional side of the pad is maintained on the body of the ambulatory patient when the support structure is worn by the ambulatory patient,
wherein the defibrillation electrode is configured to be manipulated to unshield the adhesive material to allow the second functional side of the pad to be maintained on the body of a person or the ambulatory patient with the adhesive material when the support structure is not worn by the ambulatory patient, and
wherein the pad is configured to apply a therapeutic shock through the first functional side of the pad when the support structure is worn by the ambulatory patient, and through the second functional side of the pad when the support structure is not worn by the ambulatory patient.

7. A method of operating a wearable cardioverter defibrillator (WCD) system that is intended for a patient who is ambulatory, the WCD system including a support structure, a defibrillator, a defibrillation electrode including a wire lead, a pad having a first functional side and a second functional side, and an adhesive material arranged on the second functional side of the pad, the method comprising:
coupling the pad to the support structure when the support structure is worn by the patient with the defibrillator coupled to the support structure, wherein the first functional side of the pad is maintained on a body of the patient, the wire lead is coupled to the pad and to the defibrillator, and the adhesive material is shielded from contacting the support structure or the body of the patient;
manipulating the defibrillation electrode when the patient is not wearing the support structure, wherein the defibrillation electrode is adapted to unshield the adhesive material; and
adhering the pad to a body of a person or a patient using the unshielded adhesive material so that the second functional side of the pad is maintained on the person or the patient when the support structure is not worn by the patient;
applying a therapeutic shock through the first functional side of the pad when the support structure is worn by the patient, and through the second functional side of the pad when the support structure is not worn by the patient.
8. The method of claim 7 , further comprising:
uncoupling the defibrillator from the support structure to deliver the therapeutic shock when the support structure is not worn by the patient.
9. The method of claim 7 , further comprising:
uncoupling the defibrillation electrode from the support structure to deliver the therapeutic shock when the support structure is not worn by the patient.
