WEARABLE MEDICAL DEVICE WITH DISPOSABLE AND REUSABLE COMPONENTS
Embodiments of a wearable device are provided. The wearable device comprises a reusable component and a disposable component. The disposable component comprises a patient engagement substrate comprising adhesive on a bottom side, an electrode on the bottom side, a disposable component electrical connector, and a disposable component mechanical connector. The reusable component comprises a plurality of sealed housings mechanically coupled to each other and movable with respect to each other, each of the plurality of housings containing one or more of a capacitor and a controller, a reusable component mechanical connector adapted to removably connect to the disposable component mechanical connector, and a reusable component electrical connector adapted to removably connect to the disposable component electrical connector. The device can comprise a cardiopulmonary physiologic monitor or an automatic external defibrillator, among other types of devices.
1 . A method of using a wearable device, the wearable device comprising a first disposable component comprising a patient engagement substrate comprising adhesive and an electrode on a bottom side and a reusable component comprising a plurality of sealed housings mechanically and electrically coupled to the disposable component, each of the plurality of housings containing one or more of a capacitor, batteries, or a controller, the method comprising:
adhering the wearable device to a skin surface portion of a patient for a first time period; monitoring patient ECG signals with the controller and the electrode during the first time period;
removing the wearable device from the skin surface portion of the patient at the end of the first time period;
mechanically and electrically disconnecting the disposable component from the reusable component;
mechanically and electrically connecting to the reusable component a second disposable component comprising a patient engagement substrate comprising adhesive and electrodes on a bottom side;
applying the second disposable component to a skin portion of the patient; and
monitoring patient ECG signals using the controller and the electrode of the second disposable component.
