Description

Sputum aspirator

Technical Field

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

Background

Respiratory diseases are common and frequently-occurring diseases, and are mainly caused by the diseases of trachea, bronchus, lung and chest, and the patients with light diseases are affected by cough, chest pain and respiration, and the patients with serious diseases are caused by dyspnea, hypoxia and even respiratory failure. Mortality in cities takes the 3 rd place, and rural areas take the first place. It is more important to pay attention to the increase or decrease of the incidence and death rate of chronic obstructive pulmonary disease (chronic bronchitis, emphysema and pulmonary heart disease for short), bronchial asthma, lung cancer, pulmonary diffuse interstitial fibrosis, pulmonary infection and other diseases at home and abroad due to atmospheric pollution, smoking, aging population and other factors.

For patients with respiratory diseases, many diseases can cause excessive secretion of sputum, block respiratory tract, cause dyspnea and suffocate and die when serious. Therefore, the respiratory department must be equipped with a sputum aspirator to treat sputum as soon as possible when sputum is blocked in the respiratory tract. For the existing sputum aspirator, a negative pressure pump is often combined with a sputum aspirator bottle, and a pipeline is used for inserting into the throat of a patient to perform sputum aspiration treatment. The sputum suction device is required to be disassembled and cleaned after sputum suction, but the sputum has larger viscosity, can be attached to the inner cavity of the storage box, and is not easy to clean. The existing sputum suction device is inserted into the suction head of the respiratory tract of a patient, and only one direction is used for sucking sputum, if the sputum is required to be cleaned, the sputum needs to be rotated in the oral cavity of the patient, so that the pain of the patient can be increased.
