Which Vacuum Bell Model Should You Choose? A Practical Guide
Choosing the right Vacuum Bell is an important part of achieving the best possible results in the non-surgical treatment of Pectus Excavatum. This guide explains how to select the correct model based on age, anatomy, chest shape and comfort needs.
Why Does Correct Model Selection Matter?
A properly selected Vacuum Bell provides:
- a secure seal for effective vacuum pressure,
- greater comfort during use,
- faster visible improvement,
- reduced risk of air leakage or discomfort.

Recommended for:
- children aged 6–12,

- teenage girls who do not feel comfortable using the Classic model,
- women with sensitive chest areas.

How to Take Your Chest Measurement (With Templates)
Use a soft tape measure and, if needed, print the measurement templates before ordering your device. The following templates are available:
- Large model template (26 cm): download template
- Small model template (19 cm): download template
- Woman model template: download template
- Mini model template (if recommended by your clinician): download template
After printing, place the template on the chest to check coverage and position relative to the depression.
Which Model Should You Choose?
As a general guideline:
- 19 cm model → narrow chest, mild deformity
- Woman model → female users of any age
- 26 cm model → wider chest, moderate–deep deformity
