Technical Field
The utility model relates to a inhale phlegm apparatus technical field, concretely relates to sample sampling device of phlegm is inhaled to closed.
Background
The sputum aspirator is commonly used for carrying out conventional sputum aspiration, tracheotomy and other treatments on the sick and wounded, and is an indispensable important tool for preventing and treating respiratory tract obstruction and rescuing asphyxia of patients. The sputum aspirator can adopt an open type sputum suction method or a closed type sputum suction method. The closed sputum suction method has the advantages of not interrupting treatment of the breathing machine, avoiding cross infection and environmental pollution, reducing workload of nursing staff and the like, and is widely used for clinical treatment and nursing of infectious diseases. The closed sputum suction method generally utilizes a closed sputum suction tube to connect a liquid storage bottle and a negative pressure aspirator for sputum suction. The sputum is in the liquid storage bottle.
For the treatment of infectious diseases, it is often necessary to sample the aspirated sputum for analysis. Because the sputum suction tube of the closed sputum suction method is positioned in the protective sleeve, the sputum suction tube is inconvenient to sample. The method that is commonly used at present is to take a sample from the liquid storage bottle, and the connection between the sputum suction pipe and the liquid storage bottle needs to be disconnected or the liquid storage bottle needs to be taken down during sampling. Thus, there is a risk of exposure to sputum, environmental pollution and infection.
