WIRELESS DATA COMMUNICATION PROTOCOLS FOR A MEDICAL DEVICE NETWORK
First Claim
1. A communication method for a medical device system having a first device and a second device, the method comprising:
- the first device selecting between a synchronous wireless data communication mode and an asynchronous wireless data communication mode for a wireless data communication session with the second device; and
transmitting a mode identifier to the second device, wherein the mode identifier designates the synchronous wireless data communication mode or the asynchronous wireless data communication mode, and wherein the mode identifier prompts the second device to configure itself to support the synchronous wireless data communication mode or the asynchronous wireless data communication mode as designated by the mode identifier.

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.

15. A communication method for a medical device system having a first device and a second device, the method comprising:
-
operating in a synchronous data communication mode between the first device and the second device, during which wireless data packets are exchanged in accordance with a first timing scheme; selecting, in response to an unacknowledged wireless data packet, a designated retry periodicity setting from a plurality of retry periodicity settings, each of the retry periodicity settings corresponding to a respective retry timing scheme that is different than the first timing scheme; and retransmitting at least one wireless data packet using the designated retry periodicity setting. - View Dependent Claims (16, 17, 18, 19)
