Abstract
A head immobilization device, or head immobilizer, is disclosed. The head immobilizer includes an adjustable stable structure obtained by a middle wall standing vertically above the patient's head. The middle wall in an operative condition restricts hinges from up and down movement in a first perpendicular plane, and sideways movement in a second perpendicular plane, while still allowing vertical side walls to be folded flat against the temple areas of a patient's head. This structure permits the head immobilizer to secure a large variety of head sizes. Attachment flanges for the side walls are secured to the board at an angle of approximately 90° to the middle wall. This attachment locks the structure from movement in a third perpendicular plane. The patient's head is prevented from moving forward by a restraining band joining the two side walls across the patient's forehead.
