The Supply Section provides an internal working and storage area for nursing staff. It is suspended from a trolley mounted framework which contains gloved sleeves and a supply port allowing the introduction and removal of supplies.

Filtered room air is drawn in into the Bed Isolator by an air supply unit, and passed via a HEPA filter into the Patient Section where it circulate. Air is drawn out through a double HEPA filter, and the now sterile air passes through the air supply unit into an exhaust outlet. Within the Isolator’s automatic control system, negative atmospheric pressure is maintained to ensure that contaminated air is not expelled should a leak occur. Should a fault occur in the pressure, flow or power supply an audible and visible alarm is activated.

The Patient Section provides accommodation and treatment area for the patient. The envelope is suspended from a steel framework with the bed and mattress remaining outside. Half suits and gloved sleeves are incorporated into the walls of the envelope to allow for care, medical examination and treatment of the patient whilst maintaining the microbiological barrier.
