Background

Intensive care therapy means that advanced medical technology and modern monitoring and rescuing equipment are applied to various critical patients for receiving and treating, and intensive treatment and nursing are carried out on the critical patients so as to ensure the survival and the subsequent life quality of the critical patients to the maximum extent. In intensive care units, sputum aspiration nursing devices are generally used to complete the sputum aspiration operation for patients. At present, when a patient is given phlegm in a hospital, oral mucosa of the patient is often damaged in the process of sucking oral secretions, oral bleeding of the patient is caused, the patient with poor blood coagulation function can stop bleeding, and even serious patients can have infection. In patients with tracheal intubation or patients who are not anaesthetized, the oral secretion is excessive, and VAP (ventilator associated pneumonia) can be caused if the secretion is mistakenly entered into the airway. At present, the sputum suction tubes on the market can not protect the oral mucosa of a patient well, and VAP occurs frequently. In addition, according to the statistical analysis of departments, the patient feels uncomfortable by self, which is a main reason for causing the unplanned extubation, so that for the patient who is awake but cannot swallow secretion by oneself, the discomfort of the patient is increased because the oral cavity is full of the secretion, the frequency of the unplanned extubation is increased, a large amount of manpower and material resources are consumed, and secondary injury is easily caused.
