Unlike most pediatric collars which are simply smaller versions of an adult collar, Aspen® Pediatric Collars were designed with input from nurses to meet the unique needs of children Five Sizes to Custom Fit Infants and Pediatric Patients Aspen Pediatric Collars are offered in 5 sizes specifically designed to automatically conform to provide a custom fit for infants and pediatrics. Collars are also available with a set of replacement pads. Offers Motion Restriction With the similar features as the Aspen Collar, the Aspen Pediatric Line was designed specifically for infants and pediatric patients to provide the same level of motion restriction found in the adult versions. Safe for Delicate Skin Aspen Pediatric Collars minimize the potential for skin breakdown, while maintaining a therapeutic level of motion restriction. The FlexTabs™ have been designed to spread support across the contact surfaces, helping to eliminate hot spots that can lead to skin breakdown. Custom Fit The PD 4 and PD 5 have an occipital support strap on the back panel that when adjusted, provides a custom cradle for the back of the head. Gentle by Design The pads are made of breathable, open cell foam with a soft, hypoallergenic cotton lining which helps keep the skin clean, cool and comfortable.
