14、from IHS-,-,-IEEE P1073.3.3 I D8, July 2003 ISOIIEEE PI 1073-30300ID8 Introduction This standard defines a communications transport profile. This profile supports short-range, point-to-point infrared wireless communication between medical devices, network access points, computers and other medical d
15、ata systems. This standard is suitable for new device designs but can also be implemented as an adaptation or modification of existing legacy devices. Specifically, this standard describes connection-oriented communications services and protocols consistent with standards of the Infrared Data Associ
16、ation (IrDA). The use of IrDA-infrared is especially appropriate for mobile and portable point-of-care (POC) clinical lab instruments (e.g. glucose meters) and other medical devices that require intermittent point-and-shoot connectivity to a data repository. This standard is one part of the family o
17、f IEEE 1073” (also known as “ISO/IEEE 11073”) standards. It is a companion standard to IEEE Std 1073.3.2” “Standard for Medical Device Communications - Transport Profile - IrDA Based - Cable Connected”. Since both standards use the same IrDA-based transport protocols, software development costs are
18、reduced and the implementation of simple, low-cost cable-to-infrared adapters is facilitated. Like IEEE Std 1073.3.2, this standard is compatible with ISO/IEEE 11073 upper layer standards (e.g., ISO/IEEE standards with document designators ISO/IEEE 11073-lxxxx and ISO/IEEE 11073-2xxxx). It is also f
19、ully compatible with (and largely based on) the Connectivity Industry Consortium (CIC) and the National Committee for Clinical Laboratory Standards (NCCLS) Point-Of-Care Connectiviy; Approved Standard (NCCLS POCT1) Device and Access Point Specification and is capable of supporting the Device Messagi
20、ng Layer upper layer device protocol developed by those organizations for point-of-care diagnostic devices. This standard also extends IEEE Std 1073.3.2” in several important areas: 1. Defines two additional client-server models for medical device interaction that support the NCCLS POCT1 communicati
21、on model. 2. Specifies and provides recommendations for how a network access point acts as a relay between the IrDA TinyTP connection to the medical device and a TCP/P connection to a remote host on the network, and the information that is registered at an Access Point regarding the network services
22、 provided by one or more remote hosts. Although not formally required by this standard, a key objective is that it should be possible to build a Common Access Point that can support ISO/IEEE 11073 and NCCLS point-of-care medical devices as well as handheld Personal Digital Assistants DAS), regardles
23、s of differences between their upper-layer protocols and clinical application. Page 3 of 70 Copyright O 2003 IEEE and ISO.
