Description

Sputum aspirator for respiratory system nursing Technical Field The invention relates to the technical field of medical auxiliary instruments, in particular to a respiratory system nursing sputum aspirator. Background In respiratory clinical care practice, sputum aspiration is a basic interventional procedure that maintains patient airway patency, ensures effective gas exchange, and prevents related complications. The aim is to safely, rapidly and thoroughly remove pathological secretions accumulated in the upper and lower respiratory tracts of patients, including sputum, pus, blood, gastric contents aspiration and the like. Especially for the patients with mechanical ventilation, the patients with cough reflex weakening caused by nervous system diseases and the patients with acute attacks of chronic respiratory diseases, the autonomous sputum discharging capability of the patients is often damaged or lost, if airway secretions cannot be cleared in time, the airway can be directly blocked, the pulmonary ventilation/blood flow proportion is disordered, the hypoxia and the hypercapnia are caused, and even life is endangered in serious cases. At present, a sputum suction device commonly used clinically mainly comprises a negative pressure source, a sputum suction tube, a sputum collection bottle and a control valve, and the working principle is that sputum is led out by suction force generated by the negative pressure source. However, the existing device only depends on the suction effect of the fluid negative pressure, can only effectively remove the secretion which is fallen off or has better fluidity, and is difficult to peel off the sputum scab or viscous sputum which is tightly adhered to the airway wall due to the factors such as water loss, inflammation and the like by the simple negative pressure. Operators are often forced to repeatedly attract in the same area for a plurality of times, so that the efficiency is low, and because the orifice of the sputum suction tube continuously acts on the mucous membrane part in a short distance, tissue edema, hemorrhage and even mucous membrane avulsion at the part are extremely easy to cause iatrogenic injury, and pain and infection risk of patients are increased due to repeated intubation.
