technical field

The utility model relates to a medical device, in particular to a sputum suction device.

Background technique

Clinically, sputum suction is commonly used to remove respiratory secretions, so as to maintain the patency of the airway. Sputum suction is mainly suitable for: (1) patients undergoing endotracheal intubation due to various reasons; (2) patients with dyspnea due to weak cough and expectoration, such as coma, newborns, critically ill patients, and patients after anesthesia (3) First aid for suffocation, such as first aid for patients who are drowning or inhaling amniotic fluid.

For critically ill patients, endotracheal suction is a necessary nursing operation for critically ill patients who have established an artificial airway. After the patient is intubated, the function of "cilia swing" in the upper respiratory tract is weakened, and the normal cough mechanism is destroyed. Suction in the trachea can remove various secretions produced in the respiratory tract. Specifically, sputum suction is realized through negative pressure, which is generally 0.033-0.053Mpa for adults and 0.013-0.033Mpa for children. However, if the sputum suction method is improper, in addition to causing airway mucosal damage and inducing bronchial asthma, a certain amount of alveolar gas may also be taken away. At the same time, due to the increase in airway resistance after the suction tube is inserted into the catheter, insufficient ventilation will result, which will reduce the ventilation in the lungs, lead to atelectasis, and may aggravate hypoxia.

Therefore, oxygen supply is very important for some patients, such as patients with respiratory failure, chronic bronchitis, cerebrovascular disease, and coronary heart disease. Even some patients with no obvious symptoms of clinical hypoxia may also have oxygen debt and microcirculation metabolism. abnormal.
