Detecting loss of full skin contact in patient electrodes

摘要

Patient electrodes, patient monitors, defibrillators, wearable defibrillators, software and methods may warn when an electrode stops being fully attached to the patient's skin. A patient electrode includes a pad for attaching to the skin of a patient, a lead coupled to the pad, and a contact detector that can change state, when the pad does not contact fully the skin of the patient. When the detector changes state, an output device may emit an alert, for notifying a rescuer or even the patient.

主权项

1. A patient electrode adapted to be used with an output device that is configured to emit an alert, comprising:
a pad configured to be attached onto a skin of a patient; an electrode lead coupled to the pad; a plug coupled to the electrode lead, and adapted to be plugged into a socket; and a contact detector coupled to the pad, the contact detector adapted to be in one of a plurality of detector states, and in which the output device is adapted to emit an alert responsive to a determination from a current one of the detector states that the pad does not contact fully the skin of the patient.
