Size Selection Guidelines for ThumbGuard/FingerGuard
(Please read the guidelines and carefully consider your selection)
The ThumbGuard appliance comes in three sizes:
- Small
Children below 4 years of age whose weight is below 14 kilograms.
Children who are taller than average but have small bone structure
Children over 4 years of age who are small for their age. - Medium
Children 5 to 6 years of age whose weight is between 14 and 25 kilograms.
Children under 5 years old whose physical development is above average
Children over 6 years old who are small for their age
Children over 6 years who are tall for their age but have small bone structure - Large
Children 7 years of age and older whose weight is above 25 kilograms.
Children 6 years old whose physical development is above average.
If you find that your child is between two sizes, we recommed you select the larger size, for the following reasons;
- Choosing a larger size will guarantee better air flow inside the tube to prevent a seal that could be caused by suction
- Improved ventilation inside the tube will reduce condensation and moisture that could cause skin irritation
