What is CAREWAY?

CAREWAY is an airway clearance oscillator which was developed and commercialized with a patented technology by Korust Co., Ltd. CAREWAY obtained a CE certification and a patent. Its effectiveness and efficiency are well recognized worldwide where it is currently being sold.

CAREWAY uses high frequency air vibrating waves generated from a sealed air cylinder with high-speed, high-capacity air filled into, which is specially built into the device. When the cylinder is repeatedly compressed and released at high speed, the high frequency air vibration waves are generated.

When the air vibration wave is supplied to a specially manufactured air vest, the chest wall is subjected to rapid and repeated compression and relief.

This force acts equally on the lungs through the chest wall, causing the lung tissue to vibrate, and the viscoelasticity and smoothness of the lung secretions (sputum) located deep in the capillaries or bronchioles are physically reduced, resulting in a respiratory mucus shear effect.

In particular, the shear effect of secretions from the lining of the lungs caused by high-frequency repetitive vibrations occurs more frequently than coughing, which is more effective for the discharge of pulmonary secretions. Through this process, the separated lung secretions are pushed up to the upper airway. The compressed force of the vest causes a “Staccato cough” (short and sharp cough) in the patient, which makes the patient spit out the pushed up lung secretions on their own or with suction.

    Applied patented technology

    Acquisition of a patent for a high frequency air-pulse generating device, which is the core technology of the high frequency chest wall oscillator, enables the efficient generation of high frequency air pulses according to the condition and needs of the patients.

    The most effective chest physical therapy (CPT)

    CAREWAY is a medical device used for high frequency chest wall oscillation therapy, one of the airway clearance treatments, which does not require special skills or breathing methods. The treatment stress is significantly low because there is no need for changing in the patient's position. Also, the discharge of lung secretions is greater than that of other treatments.

    Various indications

    CAREWAY can be used without restrictions on the patient's condition and can be applied from adults to children who are more difficult to treat. It can be also used to improve breathing in patients with reduced lung function. Its indications are gradually expanding through domestic and international research.

    CAREWAY reduces costs in drug treatment for relief of inflammation in the bronchi and treatment time for sputum (pulmonary secretion) discharge.
    (According to statistics, the treatment time is reduced for critically ill patients who require nursing assistants).

    Safety and Convenience

    CAREWAY makes continuous and independent treatments with no treatment stress, which makes the high patient satisfaction and compliance.
    It can be used on an outpatient basis and can be treated during daily life and activities rather than inpatient treatment.
    CAREWAY has relatively few side effects from treatment, and there is no age limit for use, which makes a wide range of treatment possible.


  • When it is necessary to promote the excretion of sputum (pulmonary secretions) to prevent worsening of symptoms.

    CAREWAY, the high frequency chest wall oscillator, helps to excrete the mucus deposits (sputum, lung secretions) in the lungs by transmitting vibrations to the chest wall of the patient.

    When it is difficult to cough voluntarily.

    When lung secretions cannot be removed naturally (due to a spinal injury after chest surgery, multiple sclerosis, critically ill patients, and scoliosis)

  • Helps people who have difficulty in excreting sputum (pulmonary secretions) due to chronic lung disease

  • If spontaneous breathing is difficult due to other neuromuscular diseases

    A high-frequency chest wall oscillator is a treatment for airway clearance related to respiratory diseases. It induces the discharge of sputum in patients who have difficulty breathing spontaneously due to neuromuscular disease by facilitating the discharge of pulmonary secretions using a high-frequency chest wall oscillator.
