Embodiment Construction

[0025] figure 1A medical body area network (MBAN) 10 implementing a channelization scheme and channel usage regulation for IEEE 802.15.4j standardization is shown. In a first channelization scheme, non-overlapping channels are defined in the MBAN spectrum that can only be accessed on coordination from within the healthcare facility, while overlapping channels that can be accessed anywhere are defined within the first part of the MBAN spectrum. The fixed non-overlapping channels defined in the second part of the MBAN spectrum will simplify implementation and facilitate coexistence with other in-band MBAN users (eg, IEEE 802.15.6 radios, etc.) within the healthcare facility. At the same time, the overlapping channels defined in the first part of the MBAN spectrum provide flexibility for out-of-hospital MBAN applications to mitigate mutual interference with other users in the second part of the MBAN spectrum. The second channelization scheme improves spectrum usage efficiency in...

Abstract

A medical system includes one or more medical body area network (MBAN) systems. Each MBAN system includes one or more MBAN devices which acquire and communicate patient data with a hub device via short-range wireless communication. The communication of the patient data via the short-range wireless communication is within a predefined spectrum. The hub device receives patient data communicated from the one or more MBAN devices and communicates with a central monitoring station via a longer range communication. A MBAN channelization scheme defines one or more overlapping channels in the predefined spectrum and a MAC parameter dynamically enables or disables access to each defined channel.A channel regulator manages the MBAN utilization of the predefined spectrum by setting the MAC parameter todynamically enable / disable the one or more predefined MBAN channels within the predefined spectrum.

Description

technical field [0001] The present application relates to medical monitoring and clinical data devices for monitoring the physiological condition of patients. It has unique application in the use of channelization schemes and channel usage regulation for IEEE 82.15.4j standardization. Background technique [0002] Rapid developments in physiological sensors, low-power integrated circuits, and wireless communications have enabled the adoption of next-generation medical body area networks (MBANs) for monitoring patients. MBANs provide low-cost wireless patient monitoring (PM), overcoming the inconvenience and safety hazards of wired connections that could trip medical personnel or potentially lose medical data by becoming disengaged. In the MBAN approach, multiple low-cost sensors are attached to different locations on or around the patient. These sensors take readings of a patient's physiological information, such as patient temperature, pulse, blood sugar levels, electroca...
