Cabling standards for the North American medical profession

Medical industry in the integrated wiring is a relatively special user. Compared with other business users, the medical profession, especially the large hospitals, needs to consider more aspects when building. For example, in the hospital, when the start of the construction of the need to consider a good enough channel and space, so that in the future when demand changes can be expanded according to need. Especially in the need to isolate the environment, if you want to add a wall to go through the hole will become very troublesome. There are some special application needs in the medical industry that make it necessary to separate them from commercial buildings and set standards for them.

In August 2009, Tia's TR42.1 team, after years of research and development, submitted a draft of a comprehensive wiring standard for the medical profession. The draft was studied as early as 2003 and started almost at the same time as the 568C, but in order to avoid duplication of definitions, the submission of the draft was postponed until Ansi/tia-568c was released. After the release of this standard, it will become an important member of TIA's comprehensive wiring standard, and it is the supplement and refinement of the 568 standard series. The draft is drawn from the design/construction, medical users, wiring products production and medical information systems and many other aspects. Therefore, the formulation of the draft fully takes into account the medical industry's information technology standards, such as HITSP (Healthcare information Technology Standard Panel) in the guidance of the framework, the actual use of the product and the characteristics of the future development. According to the plan, the draft will be officially published in February 2010 as the ansi/tia-1179 standard (medical communication wiring standards), which is the future North American medical industry integrated wiring design guidelines and principles. At present, there is no similar standard in our country, so it is important to know the design and construction of the integrated wiring system of our domestic hospitals.

The draft standard sets out the requirements for communication systems, infrastructure, medical facilities, including cable types, topology and distance requirements, space requirements, and the wiring design and installation requirements for health care facilities. The aim is to support a wide range of applications, including other building automation systems, nurse calls, safety, outpatient tracking, drug inventory, clinical and non clinical systems, and more. In the system architecture, compared to 568C, there is no big difference, but in some detail, the draft has done more in-depth refinement. Here's a brief introduction to the different parts of 568C. Since the standards have not yet been released, the draft may be different from the final version.

The system structure in the draft directly refers to the provisions in the 568C.1

Because medical facilities are different from commercial buildings, they provide basic services that relate to people's lives and safety. Disruption of communications services will have very serious consequences, particularly in the emergency centres. Therefore, in the EF (Entrance Facility) section, the draft stipulates the redundancy and back-up of the line, especially the need for the emergency center to have multiple telecommunications access points and the path cannot be the same. Similarly, with respect to the floor wiring, the draft stipulates that the floor wiring/equipment should be at least 12 square meters, and that the backbone link between the main wiring and the floor equipment leading to the emergency and intensive care areas must have more than 2 paths. With regard to the level and backbone link cabling section, the draft uses the relevant provisions of 568C, but it is more recommended to use a higher bandwidth design to minimize possible future modifications.

Compared to the 568C standard, the whole draft changes the most is its refinement of the workspace. First, the wiring density of the workspace or area of the work area is defined as 3 levels: high, medium, and Low,

Recommended low density for 2-6 information points (outlets)

Recommended medium density for 6-14 information points (outlets)

Recommended high-density for 14 information points (outlets)

But if you take into account the new business and applications, minimize the need for upgrades. The number of information points should be above the middle point of the recommended quantity range. For low density areas, for example, the draft is recommended at 4-6 points.

Depending on the functional area, the draft divides the medical facilities into the following large areas: 1 Patient Service Area 2) Outpatient District 3 Operating Room 4) emergency/First Aid area 5) Maternity Area 6) Clinics 7) Rehabilitation Care Area 8) Depot 9) Logistics Area 10 Operation Management 11) intensive care. Then, according to the characteristics of each large area, the wiring density of the corresponding sub area or room is recommended. Specifically as follows:
