Abstract

The present invention is directed to an improved method, system and product to provide wireless ECG patient monitoring. Although embodiments make specific reference to monitoring electrocardiogram signal with an adherent patch, the system methods, and device herein may be applicable to any application in which physiological monitoring is used. Unlike prior art methods and devices which require a wired solution to enable patient monitoring, this solution presents a safe, intuitive means ECG measurements without the use of wires. Also, the present invention also presents a reliable means for docking the interface while minimizing signal interference and user error. In addition, a novel means for transmitting and receiving a patient'"'"'s ECG measurements is introduced which includes the use of an epidermal communication network (ECN). Although embodiments make specific reference to the use of the ECN for ECG measurements, the system methods, and protocol herein may be applicable to any wearable device and/or other smart device which is ECN enabled.

Claims

1. A leadless ECG measurement system for measuring of bio-potential electrical activity of the heart in a patient'"'"'s body, comprising:

a multi-contact electrode assembly adapted for attachment to the patient'"'"'s body;

a plurality of contact points for engagement with the surface of the patient'"'"'s body and configured to measure short-lead ECG signals in response to electrical activity in the heart;

a processing unit configured to produce a transfer function which computes estimated long-lead ECG signals based on the measured short-lead ECG signals from said plurality of contact points, wherein said leadless ECG system is wireless, includes a transceiver unit for transmitting and receiving wireless communications and is placed on top of the cardiac area on the surface of the patient'"'"'s skin in proximity to the cardiac area;

a head-mountable support structure comprising a frame configured to be worn on the head of a user, the frame including a bridge configured to be supported on the nose of the user wherein the bridge is adjustable for selective positioning to an eye of the user through a generally transparent display; and

an input device affixed to the frame and configured for receiving from the user an input associated with a heart monitor function transmitted from the processing unit, wherein information related to the function is presentable on the display;

wherein said ECG measurement system is operably associated with a smartphone having a non-transitory computer-readable storage medium storing a set of instructions that when executed, records an electrocardiogram (ECG) from the patient, said electrode assembly having at least four electrodes that are arranged in parallel lines.

2. The system as set forth in claim 1, where the electrode assembly and processing unit form a monitoring device configured to include a user interface having a magnetic contact configuration adapted to permit a doctor to retrieve a patient'"'"'s information by means of a scroll wheel, said monitoring device comprising a multi-input capacitive touch user-interface with said magnetic contacts positioned at various locations along the wheel to access services selected from the group consisting of a patient'"'"'s records and ECG data.

3. The system as set forth in claim 2, wherein the monitoring device communicates via an epidermal communication network, wherein the epidermal communication network includes transmission and reception of a plurality digital and/or analog signals across an epidermis of a body, wherein the epidermal communication network provides a medium for transferring the patient'"'"'s information from the monitoring device to one or more secondary devices, wherein the one or more secondary devices include one or more of an:

epidermal communication network enabled wearable device, an wired external device with an epidermal communication network enabled interface, a wireless external device with an epidermal communication network enabled interface, a smart module docketed on an epidermal communication network enabled interface, and/or an ingestible sensor, wherein the patient information includes vital records, demographic information, personal information, credentials, and/or bank information, wherein the personal information is encrypted and necessitates the use of a fingerprint scanner to access.
