Adherent device for sleep disordered breathing
First Claim
1. An adherent device to monitor an apnea and/or hypopnea of a patient for an extended period, the device comprising:
- a breathable tape comprising a porous material with an adhesive coating to adhere the breathable tape to a skin of the patient;
at least one electrode affixed to the breathable tape and capable of electrically coupling to a skin of the patient;
at least one gel disposed over a contact surface of the at least one electrode to electrically connect the electrode to the skin;
a printed circuit board supported with the breathable tape when the tape is adhered to the patient, the circuit board connected to the at one electrode with a flexible intermediate connector to provide strain relief between the printed circuit board and the at least one electrode;
electronic components electrically connected to the printed circuit board and the at least one electrode to measure breathing of the patient and determine the apnea and/or hypopnea of the patient;
an electronics housing adhered to at least one of the electronics components or the printed circuit board; and
a breathable cover disposed over the circuit board and the electronic components such that the electronics housing is disposed between the cover and electronics components, the breathable cover connected to at least one of the electronics components, the printed circuit board or the breathable tape.

Abstract
An adherent device is configured to adhere to the skin of the patient with an adherent patch, for example breathable tape, coupled to at least four electrodes. The device comprises impedance circuitry coupled to the at least four electrodes and configured to measure respiration of the patient to detect sleep apnea and/or hypopnea. The impedance circuitry may be used to measure hydration of the patient. An accelerometer can be mechanically coupled to the adherent patch such that the accelerometer can be coupled to and move with the skin of the patient. Electrocardiogram circuitry to generate an electrocardiogram signal may be coupled to at least two of the at least four electrodes to detect the sleep apnea and/or hypopnea.
