Its main function is to provide timely and effective sputum suction treatment for patients with severe airway sputum accumulation to ensure the patency of the airway. However, the existing sputum suction device has exposed many problems in actual use, mainly reflected in the lack of functional integration and the difficulty in further improving hygiene and safety. These problems seriously restrict the nursing efficiency of the equipment and the safety of patients;

[0003] In the existing suction devices, suction tubes, hoses and other suction parts are mostly placed by nursing staff, and there is no special storage area in the device. This practice not only wastes space, but also easily leads to the loss of parts, and even difficult to find quickly when urgently needed, and the parts need to be disinfected again before use; secondly, in the intensive care unit of the Department of Neurology, patients are often adversely affected by suction operations, such as heart rate fluctuations or respiratory arrest. However, the existing suction devices lack the function of real-time monitoring of patients' vital signs. Nursing staff can only operate based on experience and cannot quickly identify abnormal conditions of patients. Even if the patient is If abnormal heart rate or increased airway resistance occurs during suctioning, the automatic protection mechanism cannot be triggered. As a result, it is difficult to intervene in time for sudden risks, which not only increases the patient's life risk, but also makes the operation of nursing staff more tense. Finally, the fixing and cleaning of the liquid storage bottle are often done manually.
