The Vacuum Bell is a non‑surgical, non‑invasive device for correcting pectus excavatum. Through its professionally designed suction cup, it uses the principle of negative pressure to gently lift the chest wall, allowing the sternum to gradually return to a near‑normal position.
Main functions:
Improves the appearance of chest wall depression
Supports gradual correction of the sternum and ribs
No surgery or hospitalisation required
Can be used safely at home
Applicable age: Children and adolescents aged 1–18 years
Indications:
Mild to moderate pectus excavatum
Chest wall is flexible and not yet fully ossified
As a pioneer in thoracic and pediatric surgery, EMK's vacuum bell for Pectus Excavatum has been granted 4 national patents:
lRetractable Pectus Excavatum Correction Device and Preparation Method
lAn Air-Leakproof Pectus Excavatum Vacuum Bell
lVariable-Thickness Pectus Excavatum Correction Device
lPectus Excavatum Corrector
Choosing the right size = faster, more effective results
EMK offers the world's most advanced vacuum bell selection — tailored to every unique case of pectus excavatum.
Based on the patient's 3D scan or CT data, we reconstruct a precise chest model and design the vacuum bell's structure and contact surface according to individual depression patterns. This achieves true one-to-one customization, significantly improving treatment efficiency and fit stability.
Ensures precise fit over the depressed area
Breaks through the limitations of conventional sizing
Superior fit compared to traditional suction cups
Provides the optimal non-surgical solution for every patient
Made from food-grade silicone — soft, skin-friendly, and safe like a baby pacifier.
Traditional manual vacuum bells have significant limitations:
Prone to air leakage
Require constant parental supervision and manual pressure adjustment
EMK's intelligent constant pressure system features a high-sensitivity pressure monitoring module that instantly detects suction status and automatically compensates for pressure fluctuations caused by body movement or minor air leaks — maintaining stable therapeutic negative pressure for consistent correction.
Our segmented pressure control strategy applies different ramp-up rates for each pressure range, achieving gradual, gentle negative pressure increase. This effectively reduces initial discomfort and significantly improves long-term wear compliance — especially for children and sensitive users.
Treatment pressure limits can be customized based on the patient's age, body type, chest structure, and tolerance. The system automatically limits pressure to prevent over-pressurization, achieving dynamic balance between efficacy and safety.
Real-time data upload via Bluetooth
Automatic local storage when offline
Seamless synchronization upon reconnection
Ensures data continuity and integrity for long-term treatment tracking and evaluation.
Parents can track their child's usage duration, pressure levels, and treatment trends in real time through WeChat Mini Program. Data can be shared with doctors or other family members, enabling remote treatment adjustments and collaborative care.
One-key automatic operation — set time and pressure values
Precisely regulates pressure and automatically compensates for air leakage
No parental supervision required, reducing care burden
Stable pressure output supports gradual, safe, and effective personalized treatment plans
Clinical Cases
A 3-year-old patient with pectus excavatum, first noticed one year ago. The patient had tried a conventional manual vacuum bell with unsatisfactory results before switching to the EMK custom vacuum bell.
l1 month: Significant improvement observed
l2 years: Full recovery achieved; treatment discontinued
A 15-year-old patient with pectus excavatum for 3 years. Recently experienced chest tightness and shortness of breath. Patient refused surgery and chose conservative treatment with EMK.
l3 months: Noticeable improvement achieved
lOngoing: Patient satisfied and continuing treatment
A 28-year-old patient with pectus excavatum for over 10 years. Previous use of vacuum bells from other brands showed poor results with persistent air leakage. Switched to EMK 3D-printed custom vacuum bell.
l6 months: Significant improvement observed
lAdditional benefit: Physical activity ability improved
lOverall: Patient highly satisfied with results

A Vacuum Bell is a non-surgical device that uses controlled negative pressure to gently elevate the depressed chest wall in selected pectus excavatum patients.
Most children experience pressure or a pulling sensation rather than pain. Comfort levels vary between individuals, and treatment should always follow professional guidance.
Treatment duration varies depending on factors such as age, chest wall flexibility, severity of the condition, and treatment consistency. Some patients may use the device for several months, while others may require longer treatment periods.
Yes. After receiving appropriate instructions and medical guidance, many children use the device at home under parental supervision.
A professional assessment is recommended to determine whether Vacuum Bell therapy may be appropriate based on your child's chest anatomy, age, and overall condition.
