AUTOMATIC CONFIGURATION PROTOCOL FOR A PATIENT MONITORING NETWORK
A patient monitoring network may include patient monitoring units including patient monitors and monitoring stations. A patient monitor may be part of a patient monitoring system including devices for monitoring physiological activity of a patient and the patient monitor. A monitoring station may include a display and user interface to allow for monitoring of one or more patient monitors. The patient monitoring units may be connected to a network. A broadcast communication may be used by a patient monitoring unit to identify an address of other patient monitoring units. Patient monitoring units may then engage in addressed communications to allow for the display of information from one or more patient monitors at one or more monitoring stations.
1 . A method for a first patient monitoring unit to communicate within a patient monitoring network, comprising:
transmitting a broadcast message over a network;
receiving a response message to the broadcast message from a second patient monitoring unit; and
communicating with the second patient monitoring unit based on the response message.
2 . The method of claim 1 , wherein the broadcast message comprises a UDP broadcast message.
3 . The method of claim 1 , wherein the response message comprises an IP address of the second patient monitoring unit.
4 . The method of claim 3 , wherein communicating with the second patient monitoring unit based on the response message comprises:
receiving a user indication selecting the second patient monitoring unit;
associating the second patient monitoring unit with the IP address; and
transmitting TCP messages to the second patient monitoring unit.
5 . The method of claim 1 , further comprising:
receiving signals corresponding to one or more physiological parameters for a patient;
comparing the signals to at least one alarm threshold; and
transmitting an alarm message to the second patient monitoring unit based on the comparing.
6 . The method of claim 1 , further comprising:
receiving signals corresponding to physiological parameters for a patient;
storing patient data in memory based on the signals;
receiving a request for at least a portion of the patient data from the second patient monitoring unit; and
transmitting the at least a portion of the patient data to the second patient monitoring unit.
7 . The method of claim 1 , further comprising:
receiving patient identifying information from the second patient monitoring unit; and
retrieving additional patient information based on the patient identifying information.
8 . The method of claim 1 , further comprising:
receiving a second response message to the broadcast message from a third patient monitoring unit; and
communicating with the third patient monitoring unit based on the second response message.
9 . The method of claim 1 , further comprising:
receiving a broadcast message from a third patient monitoring unit over the network;
transmitting a response message to the third patient monitoring unit; and
receiving physiological parameter information from the third patient monitoring unit.
10 . The method of claim 9 , further comprising:
receiving physiological parameter information from the second patient monitoring unit; and
concurrently displaying physiological parameter information received from the second patient monitoring unit and the third patient monitoring unit.
11 . A patient monitoring unit comprising:
a transceiver; and
a processor coupled to the transceiver, the processor configured to enable the transceiver to transmit a broadcast message over a network, receive a response message to the broadcast message from at least a second patient monitoring unit, and communicate with the second patient monitoring unit based on the response message.
12 . The patient monitoring unit of claim 11 , wherein the broadcast message comprises a UDP broadcast message.
13 . The patient monitoring unit of claim 11 , wherein the response message comprises an IP address of the second patient monitoring unit.
14 . The patient monitoring unit of claim 13 , further comprising a user interface coupled to the processor, the user interface to enable a user to select the second patient monitoring unit, the processor further configured to associate the second patient monitoring unit with the IP address and enable the transceiver to transmit TCP messages to the second monitoring unit.
15 . The patient monitoring unit of claim 11 , the processor further configured to receive signals corresponding to one or more physiological parameters for a patient, compare the signals to at least one alarm threshold, and enable the transceiver to transmit an alarm message to the second patient monitoring unit based on the comparison of the signals to the at least one alarm threshold.
16 . The patient monitoring unit of claim 11 , the processor further configured to receive signals corresponding to physiological parameters for a patient, store patient data in memory based on the signals, and enable the transceiver to receive a request for at least a portion of the patient data from the second patient monitoring unit and transmit the at least a portion of the patient data to the second patient monitoring unit.
17 . The patient monitoring unit of claim 11 , the processor further configured to enable the transceiver to receive patient identifying information from the second patient monitoring unit, the processor further configured to retrieve additional patient information based on the patient identifying information.
18 . The patient monitoring unit of claim 11 , the processor further configured to enable the transceiver to receive a second response message to the broadcast message from a third patient monitoring unit and communicate with the third patient monitoring unit based on the second response message.
19 . The patient monitoring unit of claim 11 , the processor further configured to enable the transceiver to receive a broadcast message from a third patient monitoring unit over the network, transmit a response message to the third patient monitoring unit, and receive physiological parameter information from the third patient monitoring unit.
20 . The patient monitoring unit of claim 19 , further comprising a display coupled to the processor, the processor configured to enable the transceiver to receive physiological parameter information from the second patient monitoring unit, and configured to enable the display to concurrently display received information from the second patient monitoring unit and the third patient monitoring unit.
