Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical devices, in particular to a sputum suction device. BACKGROUND

[0002] Sputum suction nursing is a common medical measure for treating critically ill patients, which aims to timely suction the secretions in the respiratory tract to maintain the patency of the respiratory tract.

[0003] At present, the Chinese patent with the application number CN111632210A discloses an infection department disinfection sputum suction device, which comprises a shell, a collecting barrel, a disinfection box, a barrel cover and a conveying pipe. The shell is provided with a groove in which the collecting barrel is placed. The upper end of the collecting barrel is screwed with the barrel cover. The upper end of the barrel cover is provided with a connector B. The connector B is connected with a sputum suction pipe at the upper end. The sputum suction pipe is sleeved with a mouth plug at one end. The lower end of the barrel cover is provided with an overflow preventer. The inside of the shell is fixed with a negative pressure machine through a screw nut. The interface of the negative pressure machine is located on the outside of the shell. One side of the shell is fixed with a binding rope port. The binding rope port is sleeved with a connecting rope. The infection department disinfection sputum suction device can control the depth of the sputum suction pipe into the oral cavity through the scale provided on the sputum suction pipe. The mouth plug sleeved at one end of the sputum suction pipe can prevent the sputum suction pipe from falling and the adverse reaction of placing the sputum suction pipe in the oral cavity for a long time.

[0004] Because the end of the sputum suction pipe away from the barrel cover needs to be inserted into the patient's body, the sputum suction pipe, especially the end inserted into the patient's body, cannot be exposed in the air for a long time to avoid the internal pollution of the sputum suction pipe. Therefore, the sputum suction pipe is generally disposable, that is, it will be discarded after completing the sputum suction once. When using the device, the shell needs to be placed at a certain distance from the patient's bed. Therefore, the length of the sputum suction pipe needs to be long enough. When the patient forms a lot of sputum, sputum suction needs to be performed at different times. The disposal of the long sputum suction pipe each time will cause the waste of resources. Practical new type content

[0005] In order to save resources, the present application provides a sputum suction device.
