Full Description

Scope

The specifications and guidelines set forth in this standard are intended to define a local area network (LAN) for the interconnection of computers and medical devices. This standard defines the functions, features, and protocols of the intra-room communications subnet of a bedside communications network known as the Medical Information Bus (MIB). This communications subnet is the functional equivalent for the MIB of the Transport, Network, Data Link, and Physical layers of the Organization for International Standards (ISO) Reference Model for Open Systems Interconnection (OSI). This standard defines the services and protocols for the MIB Transport, Network, and Data Link layers. The Physical Layer, specified in IEEE Std 1073.4.1-1994 Uses EIA-485 for data transfer.Provides DC power distribution for device communications hardware.Provides a pair of special function signals for the purposes of providing device connection indications, interrupt requests, time synchronization, and frame delimiting.Specifies a unique MIB connector and cable. The MIB Data Link layer offers services for data line connection, data transfer, and disconnection using high-level data link control (HDLC) procedures. The Transport and Network layers are inactive [i.e., there are no functions for packet assembly and disassembly (PAD) or end-to-end acknowledgments or any other services usually associated with Transport and Network layers]. See figure .

Purpose

The purpose of this subnet is to provide connection-oriented communications services. It is functional as a stand-alone network for any application entity that can directly use the transport services offered. The LAN is designed to provide a logical association between a patient and those medical devices connected to, monitoring, or otherwise data-related to that patient and in close physical proximity. New device connections are automatically detected and communications are established with those new devices without the need of any user input. The network is intended to provide a highly reliable data transfer medium with a priority on providing quantitative throughput to each attached node. The network is intended to be highly robust in an environment where devices are frequently connected to and disconnected from the network. It responds to a changing device topology by establishing new connections and detecting disconnections in a manner that is transparent to the clinical user. Hence, in regard to the device nodes on the network, it is a completely automatic and self-regulating communications subnet.

Abstract

New IEEE Standard - Inactive-Withdrawn. Withdrawn Standard. Withdrawn Date: Jan 25, 2005. A local area network (LAN) for the interconnection of computers and medical devices is defined by the specifications and guidelines set forth in this standard. The functions, features, and protocols of the intra-room communications subnet of a bedside communications network known as the Medical Information Bus (MIB) are defined. This communications subnet is the functional equivalent for the MIB of the Transport, Network, Data Link, and Physical layers of the Organization for International Standards (ISO) Reference Model for Open Systems Interconnection (OSI). This standard defines the services and protocols for the MIB Transport, Network, and Data Link layers.
