Rigid cervical collar made of cross-linked polyethylene foam of 11 millimeters, easy to place thanks to its design that opens in two to place it without moving the patient, also has occipital and chin support to maximize patient comfort. Its tracheal opening allows ventilation and, if needed, quick and direct access to the trachea. With immobilizing support, its rivets are radiolucent so that X-rays can be taken without having to remove it, thus ensuring a better recovery. It is water resistant and is indicated for severe cervicalgia treatments, adapting to a neck circumference between 33 and 40.6 centimeters.
