The utility model relates to the technical field of
medical instruments, in particular to a portable
sputum suction device for severe illness, which comprises a
sputum storage structure, an extraction structure, an
intubation structure and an air slowing chamber, a connector mounting seat is fixedly mounted on the upper side of the air slowing chamber, a built-in pipeline is clamped at the inner top of the connector mounting seat, and a tank body sealing cover is fixedly mounted at the bottom of the air slowing chamber. A
sputum storage tank is screwed on the bottom side of the tank body sealing cover; one end of the extraction structure communicates with one side of the air slowing chamber; one end of the
intubation structure is communicated with the upper side of the interface mounting seat. According to the utility model, a proper disinfection
solvent is selected to be filled into the sputum
storage tank, the
intubation structure is inserted into the
respiratory system of a patient, the extraction structure is started to extract air, a negative pressure space is formed in the sputum
storage tank, the built-in pipeline and the intubation structure extract sputum in the
respiratory system of the patient, and the sputum can directly enter the disinfection
solvent in the sputum storage tank; the germs are directly killed.
