Slide the back of the collar, with the elliptic hole, behind the patient’s neck. Continue pushing beneath the patient until you can reach it on the opposite side.
Wrap the front side around the lower jaw, aligning the oval hole under the chin. Secure the collar tightly around the patient’s neck using the Velcro strap.
Push the small wings against the chin and check that they are in a supportive position. Adjust the collar into a position that immobilizies the neck of the patient and readjust the Velcro strap if necessary.
