Lung Flute

Toothbrush for the Lung

The Lung Flute, a small hand held device, generates acoustic (sound) waves, which loosen, mobilize, and eliminates secretions deep in the lungs.

Generates resonance like a string instrument

Thins secretion by activating the aqueous phase and breaking the hydrogen bonds thinned Secretion, results in Patient coughing and clearing

Physiology of the Lungs

Human lungs possess a natural means for clearing lung secretions. Natural rhythmic 'beating' motion of cilia creates vibration between 16-25Hz. Frequency of oscillation keeps mucus phase in a liquid state, mucus fluid can now be easily moved by natural motion of cilia and Mucus is expelled by coughing or swallowing

Physics of the Lung Flute Acoustic sound waves are amorphous, and will travel deeper into the lung structure than conventional pulsed air device

Patient exhales through the Lung Flute -operating pressure of 2.0-2.5cm H2O

Reed oscillation, horn design and lung cavity act in parallel to produce sound frequency making the secretions thinner and more easily expelled by coughing. Lung Flute operation act in parallel to produce sound frequency between 16-25Hz.

Lung Flute supplements the natural mucus clearing system by artificially vibrating the airways and cilia.

The Advantages of Applied Acoustics

  • Acoustics waves travel deep into all the distal areas of the lungs
  • Operates at a low pressure; more compatible with many patients

COPD, Asthma, Pneumonia, Tuberculosis, Lung Cancer, Cystic Fibrosis


Airway Clearance / Bronchial Hygiene Therapy
The Lung Flute is a non-invasive device designed to improve gas exchange by mobilizing and
removing retained airway secretions

Diagnostic use:

Genotyping pulmonary TB, identifying infectious agents & inflammatory markers, cell-typing pneumonia, early detection of lung cancer

Drug discovery and research requiring deep lung sputum samples

Physician Testimonials

"The Lung Flute provides physicians with a modality to help patients clear their lungs of debilitating lung congestion and take more control over managing their COPD"

Sanjay Sethi, MD FACP Division Chief, UB School of Medicine

"The Lung Flute is really an excellent device. Everyone that I gave it to has said it is the best thing they have ever used, even my very severe asthmatic patients who struggle with secretions"

Serpil Ezurum MD, Pulmonary, Allergy, and Critical Care Medicine -Cleveland

"The device allows our therapists to focus their treatment times on functional training instead of performing conventional manual chest percussion/vibration for secretion clearance. The results have shown improved secretion clearance by the patient and increased efficiency in the utilization of our staff/treatment times based on functional improvement"
