Abstract
A compact integrated patch may be used to collect physiological data. The patch may be wireless. The patch may be utilized in everyday life as well as in clinical environments. Data acquired by the patch and/or external devices may be interpreted and/or be utilized by healthcare professionals and/or computer algorithms (e.g., third party applications). Data acquired by the patch may be interpreted and be presented for viewing to healthcare professionals and/or ordinary users.
Core Innovation
The invention describes a compact wireless ECG patch system that includes a base having electrodes configured to gather information sufficient to generate at least three limb lead signals, with the base having a diameter of less than or equal to 5 inches. The patch includes a cover coupled to the base and an electronic module housed between the base and the cover.
The electronic module is configured to interface with the electrodes and includes one or more non-electrode sensors configured to gather other information. The electronic module comprises a first instrumentation amplifier configured to receive and amplify signals from a first electrode and a second electrode to generate a first differential input signal, and a second instrumentation amplifier configured to receive and amplify signals from a third electrode and the second electrode to generate a second differential input signal.
The at least three limb lead signals are generated by calculating differentials between the first differential input signal, the second differential input signal, and a third input signal. The system further includes a radio in communication with the electronic module that wirelessly transmits or receives data.
The described architecture supports generating limb leads and augmented limb leads, and it is integrated with additional capabilities such as alerts, lead-off detection, respiration handling, and pacemaker signal handling, while wireless operation is described for external devices and clinical monitors using a triple-mode hybrid radio.
