  • Patent number: 6254560
    Abstract: A cervical collar in which a sternum brace has an extension extending below the clavicle of the patient and to which a footplate is attached so that the footplate rests on the sternum of the patient. Also, certain components of the cervical collar, for example a jaw support and the sternum brace, are secured together to permit relative sliding movement between these components. Further, to accommodate the differences in the anatomy of a child from the anatomy of adult, the jaw support is mounted to the sternum brace so that the jaw support is disposed below the shoulder of a patient and an occipital support is mounted to a back support at an angle greater than forty-five degrees.

  • Patent number: 5437612
    Abstract: A cervical collar is provided which has front and rear semi-rigid portions, attached by hook and loop fasteners. The front portion-comprises a semi-rigid preformed jaw support contoured to follow the jaw line of a patient, and a preformed sternum brace contoured to contact the sternum and upper trapezius of the patient and to support said jaw support. The rear portion of the cervical collar is contoured to follow the curve of the back of the head or occiput and to support the head and neck. The sternum brace has right, left, and central sections, wherein the height of the central section is adapted to correspond to the distance between a patient's sternum and jaw at the chin and the height of the right and left sections is adapted to correspond to the distance between a patient's upper trapezius muscle and jaw. The height of the right and left sections is independent of the height of the central section. Further, the jaw support may include a cushioning pad and a covering of anti-decubitus material.
