Open medical system

An open medical system for deploying, supporting and organizing medical equipment and medical utilities comprising a utility connection, and a main assembly having an upper plate and lower plate held in fixed spaced apart relation by a plurality of spacers, at least one core located between the upper plate and lower plate, with each core having at least one utility supply line and one outlet. An open space bounded by the upper and lower plates and the inner surfaces of the cores is free of utility outlets. Equipment rails are connected between the spacers to support medical equipment.The utility connection can be a ceiling tube or a base assembly, permitting the supplying of utilities from above or below the main assembly. Alternatively, the system can be supported by a support which can be a base assembly and can rotate. A rotating base assembly can be used to restrict rotation, and several alternative means can provide indexed rotation. Alternatively, the support can be provided from above the main assembly by a fixed support, or a moving articulating arm, or from both above and below.
