Author：Hanada E.Title：Smart Age and Cable Congestion in the Hospital CeilingAnnouncement information:CIVILMEET2022Keyword：Hospital Construction, cabling, wireless commuinciationAn abstract：Hospital buildings are extremely complex. All rooms must be equipped with electricity and air conditioning. Medical gas lines must be installed in rooms for serious patients and operating rooms. With advances in technology, wiring for nurse call systems, the antennas of medical telemetry systems, and that related to wireless LANs, have become essential. This complex environment must be carefully planned and implemented.
Unlike in stores and offices, the wiring and piping tends to be placed in walls and ceilings so that it is not visible in corridors and hospital rooms. This is partly for aesthetic reasons, but also because of patient safety, a top hospital priority, by preventing falls and injuries caused by exposed wiring.
In Japan, and most likely many other countries, the design and installation of communication cable, wiring, and equipment, including ICT-related equipment, is often left until the final stages of construction, especially in large hospitals. This is because they are treated as equipment, not as an integral part of the facilities. Because the amount and location of the required wiring is often not considered during the basic design and construction stages, extremely congested ceilings and difficult situations for wiring management can become problematic, causing major problems in hospital maintenance and the renovation of older buildings.
Hospitals are increasingly using wireless communication, and the antennas (access points in the case of wireless LAN) and wiring to connect routers to antennas are generally installed in the ceiling. This poses not only the problem of congestion but also the necessity of carefully designing and controlling the radio wave environment. It is important to protect against things that impact the quality of the radio waves, such as metal ducts for air-conditioning, which can reflect signals, and cables with high current, which can induce magnetic fields. Leaky co-axial cables (LCXs) are sometimes used as an antenna in wireless LAN and medical wireless telemetry systems, and it is important that they be kept away from metal. This can be difficult in a congested ceiling that has many metal components and fixtures.
To realize a "smart" hospital, the environment for communication, especially wireless communication, must be carefully managed. In this presentation, I will discuss the wiring of hospitals, focusing on the ceiling and mainly from the viewpoint of communication facilities.An abstract：Hospital buildings are extremely complex, with patient rooms, consultation rooms, examination rooms, treatment rooms, operating rooms, and nurse and doctor’s rooms necessary for the primary medical functions. Supporting these are storage rooms for materials and medicines, sterilization and food service facilities, staff offices, conference rooms, and locker rooms. All must be equipped with electricity and air conditioning. Medical gas lines must be installed in rooms for serious patients and operating rooms.
