Small-scale sputum aspirator special for pneumology department

Abstract

The invention discloses a small-scale sputum aspirator special for pneumology department. The small-scale sputum aspirator comprises a sputum aspirating tube and a rubber tube, wherein a piston rod isarranged in the sputum aspirating tube in a sleeving manner; a piston rubber sleeve is arranged at the piston end of the piston rod in a sleeving manner; a connecting tube also communicates with thebottom end of the sputum aspirating tube; a valve is mounted on the connecting tube; a collection bottle is connected to the tail end of the connecting tube; a sputum aspirating connecting tube communicates with the sputum aspirating end of the sputum aspirating tube; a sealing cover is mounted on the sputum aspirating connecting tube; biting protrusions are also arranged on the inner side of thesealing cover; the sputum aspirating connecting tube communicates with the rubber tube; a steel ball communicates with the sputum aspirating end of the rubber tube; and three sputum aspirating holes are formed in the steel ball. According to the small-scale sputum aspirator disclosed by the invention, the piston rod can be stretched outwards by medical personnel, so that aspirating force is produced in the sputum aspirating tube, and then sputum is aspirated by the sputum aspirating holes in the steel ball; when the sputum enters the sputum aspirating tube, the valve can be opened to enable the sputum to enter the collection bottle; and the sputum aspirating process is simple and convenient, the effect is good, sputum leakage cannot be generated, and germ infection cannot be generated, sothat the small-scale sputum aspirator is safe and convenient.

Description

technical field [0001] The invention relates to a sputum suction device, in particular to a small sputum suction device dedicated to the respiratory department, and belongs to the technical field of sputum suction equipment in the respiratory department. Background technique [0002] In the respiratory department of a hospital, the medical staff needs to test the patient's sputum. In the prior art, the medical staff first needs to suck out the sputum with the help of medical equipment, and the sucked sputum is manually operated for testing. During this process, the patient Sometimes the sputum is spit out, thereby bringing germs into the air, causing cross-infection between patients and medical staff, and bringing great harm to the health of patients and medical staff; The appliance has a complicated structure and is inconvenient to use, and the effect of sucking sputum is not good at the same time, which is unfavorable for use. Contents of the invention [0003] The pres...
