Abstract
Abstract This specification discloses a wall with a window in it. The wall may be in the form of a closure for a room to prevent cross contamination between service personnel and the environment in which they work. The wall has a tent-like sheet with ''''builtin'''' suits, adapters and life support equipment that permit one or more persons to perform work with a high degree of dexterity and accessability within a sealed chamber. In a lowered position, the tent becomes a closure for the window. In the raised position, the tent permits ingress and egress of service personnel. The suits are attached to the tent by means of adapters which permit access to the full length of a reclining patient. A clear plastic helmet is attached to the suit. An air supply provides air to the helmet and to the gloves through a passage formed by two layers of the plastic. The air flow prevents fogging of the inside of the helmet and helps to keep the hands dry and comfortable.
