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 provides a patch for monitoring physiological data, having a base configured to come in contact with a surface of a user and one or more electrodes operably coupled to the base to collect physiological data. An electronic module in communication with the one or more electrodes receives the collected physiological data, and the electronic module is part of a compact physiological monitoring system for wireless physiological monitoring.
The patch includes safety circuitry that reduces a voltage shock generated by an external source of electrical current. One or more resistors are operably coupled to the one or more electrodes and/or the electronic module to reduce the voltage shock, and at least two diodes are configured to be coupled back to back as a safety diode assembly.
A battery is associated with a battery voltage and includes a positive terminal and a negative terminal, with a first diode coupled to the positive terminal and a second diode coupled to the negative terminal. The safety diode assembly further reduces the voltage shock by rectifying a voltage pulse to the battery voltage. The described system supports physiological measurements such as ECG, respiration, heart rate, and SpO2, and provides a data collection device and system communication architecture to send monitoring results to a server for signal analytics and to deliver results to healthcare users and patients.

The independent claim identified (clm-00001) defines 5 inventive features combining a patch with sensing electrodes and an electronic module with shock-reduction circuitry using resistors and a battery-associated back-to-back safety diode assembly.
Base-contact electrode physiological data collection
A base configured to come in contact with a surface of a user, with one or more electrodes operably coupled to the base to collect the physiological data from the user.
Electronic module for receiving collected physiological data
An electronic module in communication with the one or more electrodes, configured to receive the collected physiological data.
Voltage-shock reduction using resistors
One or more resistors operably coupled to the one or more electrodes and/or the electronic module, configured to reduce a voltage shock generated by an external source of electrical current.
Battery with positive and negative terminals and battery voltage association
A battery comprising a positive terminal and a negative terminal, the battery associated with a battery voltage.
Back-to-back diode safety assembly rectifying voltage pulses to battery voltage
