[0002] In thoracic surgery clinical nursing work, sputum suction operation is an important means to maintain the patency of the airway of patients, prevent lung infection and protect respiratory function, and the sputum suction device as the core tool for realizing the operation is directly related to the nursing quality and the tolerance of patients in rationality of design and convenience of use, and the sputum suction tube as the key component directly contacting the airway of patients bears the core function of secretion suction and discharge. In the prior art, the sputum suction tube needs to be inserted into the body when the patient is sputum suctioned, and the medical staff needs to reciprocally rotate the sputum suction tube and synchronously perform the extraction operation during the operation. However, there are obvious defects in actual application: the sputum suction tube is easy to cause strong foreign body sensation of the patient when being placed, resulting in physical discomfort; in order to alleviate the problem, medical paraffin oil is usually applied to the outer wall of the sputum suction tube to improve the lubricity, which makes the medical staff prone to hand slipping during the reciprocating rotation and extraction operation, affecting the operation stability; at the same time, the medical staff is easy to cause the sputum suction tube to be squeezed and deformed when holding the hose to rotate and extract, resulting in the reduction of the cross-sectional area of the sputum suction tube, and further causing the sputum suction tube to be blocked, affecting the sputum suction efficiency and even interrupting the operation. In summary, the existing sputum suction device for thoracic surgery nursing has the problems of poor patient comfort, easy slipping operation and easy blockage of the sputum suction tube in actual application due to the limitations of the design and operation mode of the sputum suction tube, which not only increases the operation difficulty of the medical staff, but also may have potential impact on the treatment safety of the patient, therefore, it has important clinical significance to develop a new sputum suction device for thoracic surgery nursing which can solve the above problems.

[0036] It should be noted that when the inside of the negative pressure adsorption channel is under negative pressure, in order to avoid the collapse of the communication tube 28, the material of the communication tube 28 is hard.

[0037] Please refer to Figure 9 and Figure 10 , the lower end of the handle 22 and the end close to the shell 21 of the ventilation end 26 are fixed with a switch 49, the inside of the handle 22 is provided with a circuit cavity, the switch 49 and the driving motor 41 are electrically connected through wires, the inside of the coating cavity 25 is fixed with an energy storage element, the outside of the coating cavity 25 is provided with a charging female head, and the energy storage element and the driving motor 41, the energy storage element and the charging joint are electrically connected through wires, the outside of the sputum suction device main machine 10 is provided with a storage groove, the inside of the storage groove is provided with a charging male head, and the storage groove and the shell 21, the storage groove and the handle 22 and the charging female head and the charging male head are mutually matched.

[0038] It should be noted that the charging male head and the charging female head are both mature applications, and their specific structural forms can be referred to the prior art.

[0039] In this embodiment, since the single sputum suction should not exceed fifteen seconds, the sputum suction operation can be performed after the sputum suction device host 10 is started and the medical staff presses and blocks the ventilation end 26 with the thumb. After the ventilation end 26 is released, the airflow outside the device passes through the ventilation end 26 and the guide pipe 12 into the inside of the collection tank 11 in turn, and the negative pressure space in the inside of the sputum suction pipe 13 is no longer formed, so that the sputum suction can be stopped.
