The Ambu Perfit collar is a one-piece rigid cervical spine immobilisation device available in 4 standard adult and 2 standard pediatric sizes. The Ambu Perfit comes with a flip chin piece for flat storage and preshape to fit the chin, and to facilitate intubation and removal of vomitus from the patient's mouth. The Ambu Perfit is CT and MRI compatible, and comes with a ventilated posterior shell for fluid drainage and a large hole for easy airway access. Nasal cannula holders are located on the collar body to secure the oxygen tubes (except for infant). Ambu collars are fully disposable. You no longer have to worry about collars being returned to the source of origin and cross contamination issues are avoided.
