Abstract
Abstract The cervical traction device comprises: a body including a shoulder portion, a head portion and a bellows which extends substantially across the width and height of the body between and connected to the head portion and to the shoulder portion and acting against and between substantially the full inner end surface of the head portion and the full inner end surface of the shoulder portion. The bellows, the shoulder portion and the head portion have aligned U-shaped openings therein adapted to receive a patient's neck. A hand operated air pump is connected to the bellows for pumping air into the bellows and for relieving or pumping air out of the bellows.
