BROADCAST DATA TRANSMISSION AND DATA PACKET REPEATING TECHNIQUES FOR A WIRELESS MEDICAL DEVICE NETWORK
First Claim
1. A communication method for a wireless medical device network having a plurality of devices configured to communicate data in a synchronized manner using a common carrier frequency, the method comprising:
- a first device in the wireless medical device network broadcasting a data packet to a plurality of other devices in the wireless medical device network;
the first device receiving, in a pseudorandom order, response packets from the other devices in response to the data packet; and
the first device correlating the response packets to the other devices.

Abstract
A fluid infusion system as described herein includes a number of local “body network” devices, such as an infusion pump, a handheld monitor or controller, a physiological sensor, and a bedside or hospital monitor. The body network devices can be configured to support communication of status data, physiological information, alerts, control signals, and other information between one another. In addition, the body network devices can be configured to support networked communication of status data, physiological information, alerts, control signals, and other information between the body network devices and “external” devices, systems, or communication networks. The networked medical devices are configured to support a variety of wireless data communication protocols for efficient communication of data within the medical device network. In addition, the wireless medical devices may be configured to support a number of dynamically adjustable wireless data communication modes to react to current operating conditions, application-specific data content, or other criteria.

6. A communication method for a wireless medical device network having a plurality of devices for communicating data in a synchronized manner using a common carrier frequency, the method comprising:
-
a transmitting device in the wireless medical device network broadcasting a data packet to a plurality of other devices in the wireless medical device network, the plurality of other devices including a first receiving device and a second receiving device; receiving the data packet at the first receiving device and at the second receiving device; in response to receiving the data packet, the first receiving device generating a first response packet; in response to receiving the data packet, the second receiving device generating a second response packet; the first receiving device transmitting the first response packet to the transmitting device using a first time slot that is determined by a pseudorandom order; and the second receiving device transmitting the second response packet to the transmitting device using a second time slot that is determined by the pseudorandom order. - View Dependent Claims (7, 8, 9)

10. A wireless medical device system comprising:
-
a transmitting device to broadcast a data packet to a plurality of other devices in the wireless medical device system; a first receiving device in the wireless medical device system, the first receiving device to communicate with the transmitting device in a synchronized manner using a common carrier frequency, wherein the first receiving device receives the data packet during a first time slot; and a second receiving device in the wireless medical device system, the second receiving device to communicate with the transmitting device in a synchronized manner using the common carrier frequency, wherein the second receiving device receives the data packet during the first time slot; and the transmitting device receiving, in a pseudorandom order, response packets generated by the first receiving device and the second receiving device in response to the data packet. - View Dependent Claims (11, 12, 13, 14, 15, 16)
