Body worn physiological sensor device having a disposable electrode module
First Claim
1. A body worn patient monitoring device comprising:
- a disposable electrode module comprising a flexible circuit layer and an insulating member having an opening on opposing sides of the module, each opening sized to receive an electrode gel, the insulating member forming a bottom layer of the disposable electrode module that is adapted to be directly and non-permanently affixed to a skin surface of a patient and configured for single patient use, the disposable electrode module being crescent-shaped to enable the monitoring device to be placed on a portion of the chest or the side of a patient;
a reusable communication-computation module removably attached to an upper surface of the disposable electrode module, the computation-computation module being configured to receive physiological signals from the flexible printed circuit layer and having a microprocessor that is configured to process and analyze the physiological signals, the communication-computation module being powered upon attachment to the disposable electrode module by batteries disposed on opposing sides of the disposable electrode module, each battery disposed above an electrode; and
a series of resistive traces screened onto the flexible printed circuit layer, at least one of the resistive traces being configured as at least one series current-limiting resistor to protect the communication-computation module.

Abstract
A body worn patient monitoring device includes a flexible substrate having a plurality of electrical connections adapted to be coupled to a skin surface to measure physiological signals. The flexible substrate is adapted to be directly and non-permanently affixed to a skin surface of a patient and configured for single patient use. A communication-computation module, removably attached to an upper surface of the flexible substrate, is configured to receive physiological signals from the flexible substrate and includes a microprocessor that is configured to process and analyze the physiological signals. A series of resistive traces screened onto the flexible substrate are configured as at least one series current-limiting resistor to protect the communication-computation module.
