Abstract
A head frame for use in non-invasively determining the absolute value of intracranial pressure of a living body having a hard, flexible shield for covering the eye area of a patient. The shield has an inner surface and an outer transducer surface. An elastic film is sealed along its outer edge to the inner surface of the shield forming an expandable chamber. First and second connectors are located on the shield, permitting an inflow and outflow of pressurized liquid to the chamber. The elastic film expands inward toward the patient with an inflow of pressurized liquid, imparting a pressure against the patient's eye. An adjustable strap is attached to the shield for securing the head frame to the head of the patient.
