Abstract: A patient monitor system synchronizes patient data acquired by a plurality of sensor modules. Patient data from the sensor modules are synchronized by transmitting, from a patient monitor host, a start message that each newly connected sensor module uses to determine when to begin transmitting patient data to the patient monitor host. At a predetermined count interval, the patient monitor host also broadcasts an incrementing sequence count value to each of the connected sensor modules. The sensor modules use the sequence count values and the start message to determine when the patient monitor host expects each sensor module to transmit data packets. Each data packet sent by the sensor modules includes a sequence count value that the patient monitor host uses to align the various waveforms for display.

Abstract: Various embodiments of a rotatable electrical connector are disclosed herein that may be disposed between a patient sensor and a patient monitor. Various embodiments of rotatable electrical connectors disclosed herein may be utilized to ameliorate some of the problems of cable management in the context of patient monitoring. In various embodiments, the rotatable electrical connector may include a sensor-side power coupling and a monitor-side electrical coupling. The sensor-side power coupling and the monitor-side electrical coupling may be configured such that one electrical coupling is rotatable with respect to the other electrical coupling. A data transmission system may transmit data gathered by a patient sensor to the patient monitor. The data transmission system may comprise a transmitter on the sensor-side connector that is configured to transmit data received from a plurality of sensors to a receiver on the monitor-side connector.

Abstract: Systems and methods are provided for monitoring a patient and graphically representing ST-segment deviations. A receiver acquires, from a plurality of leads, electrocardiogram (ECG) signals that each includes an ST-segment. A processor processes the ECG signals to determine baseline and current ST-segment deviations relative to an isoelectric value. A display module displays a graph that includes a first axis representing ST-segment deviation values and a second axis representing the plurality of leads. At each location along the second axis representing a respective lead, the graph displays a first set of graphic indicia representing the baseline ST-segment deviations and a second set of graphic indicia representing the current ST-segment deviations. In certain embodiments, the graphic indicia are represented by bar graphs. In other embodiments, the graphic indicia are represented by symbols that may be connected by line segments.

Abstract: A system includes a local patient monitor and a plurality of remote patient monitors. The local patient monitor may display a plurality of physiological parameters for a local patient. The local patient monitor may further display a remote monitoring interface with the local patient's physiological parameters. The remote monitoring interface may include a plurality of status icons respectively representing the plurality of remote patient monitors. In one embodiment, the local patient monitor receives alarm information from a first remote patient monitor indicating that one or more physiological parameters for a remote patient are outside of a determined range. The alarm information may include, for example, location information for the remote patient and an alarm condition indicated by the one or more physiological parameters. The local patient monitor may display the alarm information within the remote monitoring interface.

Abstract: Patient monitoring systems can include a system for transmitting information from a patient parameter sensor to a patient monitor. The system can include an analogue-to-digital converter close to the patient parameter sensor and can transmit digital signals through a cable to the patient monitor.

Abstract: Disclosed herein are systems and method for locating medical devices on a network. The medical devices to be located comprise a unique identifier, which may be transmitted to a server over the network. The network may have a plurality of network connection points. The server may include a location subsystem configured to store a location of each of the plurality of network connection points. The server may also include a device tracking subsystem configured to store a last known device location based on the unique device identifier. The last known location of the medical device may be updated when the medical device is connected to the network based on the location of the one of the plurality of network connection points used to transmit the unique device identifier.

Abstract: A patient monitor is synchronized with a portable sensor module by detecting a first coupling of the portable sensor module to the patient monitor. In response to the first coupling, the portable sensor module and the patient monitor each store configuration settings and record patient data acquired through the portable sensor module. After the portable sensor module is decoupled from the patient monitor, the portable sensor module continues to store patient data and the configuration settings stored in the patient monitor and the portable sensor module are allowed to change relative to one another. Upon detecting a second coupling of the portable sensor module to the patient monitor, the portable sensor module and the patient monitor resynchronize with one another to remove any differences in the configuration settings and to provide copies of any patient data missing from either the portable sensor module and the patient monitor.

Abstract: A patient monitoring system allows medical personnel to customize multi-parameter alarms for particular patients and/or medical conditions. A patient monitor provides a user interface that allows medical personnel to create custom alarms by selecting patient parameters, desired levels or limits, comparators, and logic connectors to define an alarm condition that includes boundary conditions for a plurality of different patient parameters. A user may also link or group the different boundary conditions to define an order in which to process the various logic connectors.
