Patent ID: 8744875

Claim:
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.
