Abstract

Recent advances in technology have brought a variety of leading age technology devices into the operating room. The additional equipment  increased the  amount of signals in the operating room, resulting in clutter of lines, cables, tubes and wiring running in all directions, taking up space of the operating-room, blocking passages and generating the "spaghetti effect".
The goal of the study was to analyze the function of the man/machine /environment  " (patient; staff/ operating room/equipment)" and to suggest alternative solutions, at the conceptual level, for reduction of the physical/electrical wiring and tubing in the operating room.
Data were collected  from continuous video recordings conducted in the operating room,  personal  interviews with surgeons, anesthetists, technicians, and search of technical/medical database.
The equipment in the operating room has been sorted by various categories,, input - output relationship were defined, and the problem of excessive equipment resulting from the conduct of the wiring and tubing has been understood, electrical signals were divided by  range and frequencies and flow charts and information flow were created.
Through the task analyses, the relations among the functions and the major processes had been discovered. Alternative solutions are presented in two levels: a. Substituting the wiring with wireless transmission using Radio Frequency (RF) and Infra-Red (IR) technology. b. Routing the physical tubing to non-intrusive tracks, using upper ceiling and lower story  solutions. We believe that the cordless/ wireless solutions presented will decrease the clutter in the operating room and increase the safety of the patient and the staff.
