Sputum excretion device

Technical Field

The utility model relates to the field of medical equipment, especially, relate to a sputum discharging device.

Background

Respiration is an essential feature of the human body, and abnormal respiration is often accompanied by the occurrence of diseases. And the lungs are the most important organs of the human respiratory system. Our lungs constantly produce mucus, which is a natural way to protect the lungs from infection. In a healthy lung, the patient swallows mucus naturally. Airway clearance therapy is becoming increasingly important when a person is no longer able to effectively clear lung mucus on their own, helping to prevent infection and inflammation. In recent years, epidemic disease, air pollution, etc. have caused many people with pneumonia, chronic obstructive pulmonary disease, bronchiectasis and other respiratory diseases to use high frequency chest wall oscillation vests as part of a routine airway clearance procedure.

High Frequency Chest Wall Oscillations (HFCWO) are an airway clearing technique in which external Chest Wall oscillations are applied to the Chest by using an inflatable vest surrounding the Chest. The variable frequency and intensity of vibrations produced by the machine helps to loosen and thin the mucus and separate or break off the mucus from the airway wall, helping to expel the mucus out of the body (coughing or artificial suction) and thus achieve a therapeutic effect. Meanwhile, high frequency chest wall oscillations can drive the lungs to vibrate, and help make cilia move faster, help cilia bring relaxed mucus to the upper respiratory tract, and finally discharge the mucus. Conventional high frequency chest wall shaking vests have flexible plastic hoses connecting the vest, the electrical outlet to be operated and the air compressor/generator, and the air outlet releases a large volume of air to rapidly inflate and deflate the vest, thereby vibrating the chest wall. A mechanical vibration module built into the portable high frequency chest wall oscillation vest, powered by a battery to strike and vibrate the forethorax and the hindchest against the upper and lower lobes of the lungs. The patient can move freely in the using process without the limitation of the hose, the generator and the power socket of the traditional high-frequency chest wall oscillation vest. High frequency chest wall oscillations provide a good alternative to manual chest physiotherapy, and do not require skilled professional manipulation, all of which will be automated and performed correctly.
