Description

Sputum discharging device for respiratory training

Technical Field

The utility model relates to the technical field of medical instruments, in particular to a sputum discharging device for respiratory training.

Background

Respiration refers to the process of gas exchange between the body and the external environment, and can deliver oxygen to tissue cells and discharge carbon dioxide generated in vivo. Many conditions occur if a normal human cannot breathe normally. Breathing mainly has two major processes: inspiration and expiration. When a person inhales normally, the diaphragm contracts and the external intercostal muscles contract, and when the person inhales forcefully, the person also needs to inhale auxiliary muscles such as the trapezius muscles and the scalene muscles, so that the chest is widened and lifted as a result of the contraction of the muscles, the chest space is expanded to the limit, and the inspiratory muscles need to be exercised; the exhalation of a human body is caused by the fact that the pressure in the lung is over atmospheric pressure, the exhalation in normal time does not produce the contraction of muscles, when the human body exhales forcibly, the intercostal muscles and the abdominal muscles contract, the pressure in the lung is increased to the maximum, and the carbon dioxide in the human body can be exhaled in a large amount.

The difficulty in discharging phlegm is a common symptom of the respiratory system, and the clinical patients often have difficulty in discharging phlegm due to excessive phlegm, or the elderly and the infirm, chest pain, disturbance of consciousness and the like. Unsmooth sputum discharge often causes respiratory dysfunction and lung infection, and timely sputum removal is the primary care measure for ensuring the smoothness of the respiratory tract of a patient, and is also an effective method for preventing lung infection, so that it is very important to effectively remove the sputum of the respiratory tract of the patient.

With the increase of age, the respiratory muscle can become no longer powerful, and the respiratory function of the human body can be gradually reduced, and the human body can not breathe normally, so that the respiratory muscle needs to be exercised to remold the function of the respiratory muscle. The existing breathing training device generally increases the flow velocity through rapid expiration and inspiration, is applied to a plastic ball, and achieves the exercise of breathing muscles through the fluctuation of the plastic ball, but the training device can only do expiration or inspiration exercise once, and has poor continuity. The sputum is relaxed through positive pressure breathing or vibration to current sputum excretion equipment, impels the spontaneous cough of patient to carry out the sputum excretion, but can't form effective cough to the patient that respiratory muscle ability is relatively weak, and then appears coughing weak phenomenon, can't discharge the sputum.

Therefore, it is desirable to design a respiratory training sputum excretion device that can be used consistently and can exercise respiratory muscles and promote sputum excretion.
