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.

Claims

1. A patient monitor system, comprising:

a patient monitor comprising;

a sensor module interface to receive and process patient data according to a first set of configuration settings;

a first display device to display the patient data according to the first set of configuration settings; and

a first memory device to store the patient data and the first set of configuration settings; and

a portable sensor module configured to selectively couple with and decouple from the sensor module interface of the patient monitor, the portable sensor module configured to receive patient data signals directly from one or more sensors attached to a patient, the portable sensor module comprising;

a patient data acquisition unit for receiving and processing the patient data signals from the one or more sensors and to communicate the processed patient data signals as patient data to the sensor module interface of the patient monitor; and

a second memory device to store the patient data and a second set of configuration settings,

wherein in response to coupling the portable sensor module to the patient monitor, the portable sensor module and the patient monitor communicate with each other to synchronize their respective patient data and to selectively synchronize the first set of configuration settings with the second set of configuration settings, wherein the first set and second set of configuration settings define one or more display settings;

wherein the first memory device comprises a first circular buffer for storing the patient data and the second memory device comprises a second circular buffer for storing the patient data, wherein a circular buffer overwrites newest data over oldest data when the buffer is full, and wherein the patient monitor is configured to synchronize the respective patient data by;

identifying one or more memory blocks in the second circular buffer which includes patient data that is missing from the first circular buffer;

identifying one or more memory blocks in the first circular buffer having a time correspondence with the one or more memory blocks identified in the second circular buffer; and

copying the patient data in the identified one or more memory blocks in the second circular buffer to the identified one or more memory blocks in the first circular buffer.

2. The system of claim 1, wherein the portable sensor module further comprises:

a second display device; and

a user interface,

wherein the second display device and the user interface allow the portable sensor module to operate in a monitor mode that allows a user to view at least some of the second set of configuration settings using the second display device.

3. The system of claim 2, wherein the portable sensor module operating in the monitor mode is further configured to provide an alarm based on the patient data signals and to allow the user to silence the alarm.

4. The system of claim 1, wherein the patient monitor comprises a portable patient monitor.

5. The system of claim 1, wherein the portable sensor module is configured to receive patient data signals directly from the one or more sensors without passing through an intermediate device.

6. The system of claim 1, further comprising a plurality of docking stations that are each associated with a respective monitoring location, wherein each docking station stores default configuration settings associated with its corresponding monitoring location, and when the patient monitor is coupled to a particular docking station the patient monitor is configured to prompt a user to select one or more of the default configuration settings stored in the particular docking station to be part of the first set of configuration settings.

7. The system of claim 1, wherein the patient monitor comprises a first patient monitor, the system further comprising a second patient monitor, wherein the portable sensor module is further configured to be coupled with and decoupled from the second patient monitor, and wherein in response to coupling the portable sensor module to the second patient monitor the second patient monitor copies the patient data signals and the second set of configuration settings stored in the second memory device.

8. The system of claim 1, wherein the first memory device further comprises an index of patient identifiers (IDs) and the second memory device further comprises a patient ID, and wherein the synchronization of the patient data is based on an association of the patient ID stored in the second memory device with the index of patient IDs stored in the first memory device.

9. The system of claim 1, wherein the patient monitor is further configured to selectively synchronize the first set of configuration settings with the second set of configuration settings by:

determining differences between the first set of configuration settings and the second set of configuration settings;

prompting a user to select between the different configuration settings; and

updating the first set of configuration settings according to selections received from the user.
