ABSTRACT:
A head-immobilizing device for holding a patient's head, or other part of a patient's anatomy, rigidly for tomographic diagnosis or treatment comprises a head cradle having a base portion (10) and an upwardly-extending boss (12) with a concave portion (20) in the center thereof. The concave portion has a plurality of holes (22) therein and a chamber (24) thereunder. A vacuum hose (38,40,46) is in communication with the chamber. The upper rim of the cradle has a resilient sealing ring (14). A patient's head may be placed in the cradle and the chamber partially evacuated, whereby the patient's head can be held against the rim by the vacuum. A repositioning device can be used to obtain the patient's position so that the patient can be repositioned for a later treatment or diagnosis. The repositioning device comprises a mouthpiece (60) which can be unambiguously attached to the patient's head and an adjustable level (52) which can be attached to the mouthpiece in an unambiguous manner. After the patient's head is positioned, the level is adjusted to indicate a level condition. Then at a later session the positioning device is reinserted in the patient's mouth and the patient's head is adjusted until the level indicates a level condition, whereupon the patient's head will be positioned precisely in its former position. The vacuum is then applied to lock the patient's head in the former position.
