The standards developed within IEEE represent a consensus of the broad expertise on the subject within the Institute as well as those a

The existence of an IEEE Standard does not imply that there are no other ways to produce, test, measure, purchase, mar- ket, or provide other

Furthermore, the viewpoint expressed at the time a standard is approved and issued is subject to change brought about through developments in the state of the art and com- ments received from users of the standard. Every IEEE Standard is
10、subjected to review at least every fi ve years for revision or reaffi rmation. When a document is more than fi ve years old and has not been reaffi rmed, it is reasonable to conclude that its contents, although still of some value, do not wholly refl ect the present state of the art.

Comments for revision of IEEE Standards are welcome from any interested party, regardless of membership affi liation with IEEE.

When the need for interpretations is brought to the attention of IEEE, the Institute will initiate action to pre

Since IEEE Standards represent a consensus of all concerned inter- ests, it is important to ensure that any interpretation has also received the concurrence of a balance of interests.

17、 for Medical Device CommunicationsPhysical Layer InterfaceCable Connected.) This standard is a member of the 1073 family of standards for medical device communications. This particular standard specifi es the services and protocols for the Physical layer connection between a device communications co
18、ntroller (DCC) and a bedside communications controller (BCC) using an electrical cable for connection. This standard is intended to facilitate fast, reliable, and robust communications with a variety of medical devices at a single patient bedside in an integrated manner. The services and protocols d
19、efi ned address the special requirements of the medical users in the patient bedside environment. These include providing some degree of electromagnetic noise elimination, immunity to electrostatic discharge (ESD), dynamic connection and disconnection, and provision of power from the BCC to the DCC.
20、 There are no restrictions on the user entities that make use of this standard. The scope of this standard does not preclude the use of the standard for domains outside of the medical bedside environment. However, it is not the intent to defi ne the requirements for, nor to optimize this standard fo
21、r, those other domains. At the time this standard was completed, the P1073.4.1 Working Group had the following membership: Robert J. Kennelly, Chair John J.
