Flute tube and nasal and/or pulmonary secretion drainage device and method

Abstract

The invention relates to the technical field of discharging of secreta in the nasal cavity and / or the lung, and discloses a flute and a device for discharging secreta in the nasal cavity and / or the lung. The flute is used for the device for discharging the secreta in the nasal cavity and / or the lung, the flute comprises a flute body and a reed arranged in an inner cavity of the flute body, whereinone end of the reed is fixedly connected to one end of the flute body, the reed extends along the length direction of the flute body, the other end of the reed suspends in the air to form a free end,and the thickness of the reed is 0.05-0.15 mm. The thickness of the reed is 0.05-0.15 mm, so that the reed forms a very thin vibrating reed, the reed is enabled to vibrate only with a small mount ofair blowing, so that the sound waves of frequency needed for discharging the secreta in the nasal cavity and / or the lung are generated, thus the minimal peak flow needed by the device for dischargingthe secreta is greatly reduced, the user crowd is enlarged, the user crowd includes the patients suffering from intermediate and advanced chronic obstructive pulmonary diseases, other patents with weak lung function, and infant patients, and the discharge of the secreta in the nasal cavity is benefited.

Description

technical field [0001] The present invention relates to the technical field of secretion discharge in the nasal cavity and / or lungs, in particular to a flute tube and a secretion discharge device equipped with the flute tube, and a secretion discharge device in the nasal cavity and / or lungs. method of discharge. Background technique [0002] It is known that healthy human lungs have a natural mucus clearance system. In the lungs of healthy people, the cilia on the trachea wall vibrate in a single direction at a certain frequency in a coordinated and rhythmic manner, so that the viscous secretions in the trachea become diluted, that is, from a viscous state that is not easy to flow to one that is easy to flow Thin state, so the fluidity of mucus is significantly increased, it can flow with the movement of cilia, and transported to the throat, and finally discharged from the lungs through coughing or swallowing. However, in people with weak lungs, lung disease, or other cond...

Problems solved by technology

But in the same way, the applicant's investigation found that these devices also have certain deficiencies in actual use, for example, the minimum peak flow required by most products is 128.4 liters / minute, but this peak flow does not affect most of the three phases or It is not possible for patients with stage IV COPD, and these patients need sputum discharge the most. Therefore, such products cannot benign and effective to meet the needs of these patients

[0005] In addition, chronic rhinitis, sinusitis, allergic rhinitis, excessive nasal secretions due to cold inflammation and difficult to eliminate are also clinical unmet needs
