Application Instructions (Suspine) of Miami J Cervical Collar
At least two persons are needed for initial collar placement: one to maintain the patient's head and neck in proper alignment, the second to fit the collar.
- Remove any pillows from behind the patient’s head. Position patient with arms to the side, shoulders down and head centrally aligned.
- Slide the Back Piece behind the patient´s neck and center it. Ensure the blue Sorbatex padding extends beyond the edge of the plastic.
- Flare the sides of the Front out, slide it up the chest wall and scoop it up under the chin.
- Sides of the collar Front should be oriented up, off the trapezius, and toward the ears.
- While holding the Front securely, curl the ends snugly against the patient´s neck. Apply the hook and loop strap and secure the opposite side of the collar in the same fashion. Tighten straps alternately, one at a time, to an equal length on both sides. Place the Front of collar inside the Back.
- Hook and loop straps must be aligned symmetrically and oriented “blue-on-blue” to the Front adhesive sections. When the patient is properly fit, there should be equal amounts of excess hook and loop overhanging the Front blue adhesive sections. These may be trimmed. Collar application must be secure to ensure proper fit, maintain 7alignment, and to prevent the chin from slipping inside. If the patient can slip his/her chin inside the collar, it is clear indication that it is not snug enough. It is nearly impossible to fit a properly sized collar too tight.
Upright Application of Ossur Neck Support
- To fit the collar to a sitting or standing patient, follow the instructions for supine application.
- Whenever possible, fit the collar to a sitting or standing patient.
