The invention discloses a
sputum aspirator suitable for hospital
nursing, and relates to the technical field of medical assistance, the
sputum aspirator comprises a
nursing box body and further comprises a
sputum aspiration
assembly, the sputum aspiration
assembly comprises a sputum aspiration cylinder and a negative pressure mechanism which are arranged on one side of the
nursing box body, one end of the sputum aspiration cylinder is connected with a sputum aspiration end through a sputum aspiration
pipe, and the other end of the sputum aspiration cylinder is connected with a sputum aspiration cavity; the other end of the sputum suction cylinder is connected with the negative pressure mechanism through the negative
pressure pipe, the negative pressure mechanism is used for generating negative pressure in the sputum suction cylinder through the negative
pressure pipe, the negative pressure mechanism generates vacuum negative pressure in the sputum suction cylinder through the negative
pressure pipe, and under the action of the vacuum negative pressure in the sputum suction cylinder, the sputum suction cylinder can suck the sputum. The sputum suction end sucks sputum clamped in the mouth of a patient into the sputum suction cylinder through the sputum suction
pipe, then rapid sputum suction operation is achieved, the flushing mechanism conveys external cleaning liquid into the sputum suction cylinder and flushes the interior of the sputum suction cylinder, after flushing is completed, the liquid suction mechanism pumps out waste liquid in the sputum suction cylinder, and then automatic cleaning treatment on the sputum suction cylinder is completed.
