Description

A sputum suction device

technical field

The utility model relates to the technical field of auxiliary medical appliances, in particular to a sputum suction device.

Background technique

Respiratory system disease is a common and frequently-occurring disease. The main lesions are in the trachea, bronchi, lungs and chest cavity. Mild cases often cause coughing, chest pain, and respiratory problems. Severe cases have dyspnea, hypoxia, and even death due to respiratory failure. The death rate in the city is the third, while in the countryside it is the first. What should be paid more attention to is that due to air pollution, smoking, population aging and other factors, chronic obstructive pulmonary disease (referred to as COPD, including chronic bronchitis, emphysema, pulmonary heart disease), bronchial asthma, lung cancer, The morbidity and mortality of diseases such as pulmonary diffuse interstitial fibrosis and pulmonary infection have increased unabated.

For patients with respiratory diseases, many diseases will cause excessive secretion of sputum, block the airway, cause the patient to have difficulty breathing, and in severe cases, the patient will suffocate and die. Therefore, the Department of Respiratory Medicine must be equipped with a sputum suction device. When sputum blocks the respiratory tract, the patient should be sucked as soon as possible. For existing sputum suction devices, a negative pressure pump is often combined with a sputum suction bottle, and a pipeline is inserted into the patient's throat for sputum suction treatment. The sputum suction device needs to be disassembled and cleaned after sputum suction, but the sputum is relatively viscous and will adhere to the inner cavity of the storage box, making it difficult to clean. The suction head inserted into the patient's respiratory tract in the existing sputum suction device can only suck sputum in one direction. If you want to clean up the sputum, you need to rotate it in the patient's mouth, which will increase the pain of the patient.
