Description
Technical Field
The utility model relates to the technical field of medical equipment, especially, relate to a disposable inhales phlegm pipe.
Background
Sputum suction is an important emergency nursing technology, and refers to a method for sucking secretions in a respiratory tract out through an oral cavity, a nasal cavity and an artificial airway (tracheotomy) so as to keep the respiratory tract smooth and prevent complications such as aspiration pneumonia, atelectasis, asphyxia and the like. It is an invasive operation that utilizes the principle of negative pressure suction and connects the catheter to suck out sputum. The selection of the sputum suction tube is the basic guarantee of correct sputum suction. The existing disposable sputum suction tube is generally of a common tubular structure, and because the edge of the end face of the tube opening is relatively sharp, the mucosa of the trachea can be easily damaged when the sputum suction tube is inserted, and the tube opening is easily blocked. Meanwhile, in the sputum suction process, if the patient has cough, the operation needs to be suspended, the sputum suction pipe is drawn out, and the patient continues to suck sputum after the sputum in the deep part is coughed out. However, since the conventional sputum aspirator does not have a function of preventing the reverse flow of sputum, the sputum remaining in the sputum aspirator easily flows back into the respiratory tract of the patient when the sputum is withdrawn.
SUMMERY OF THE UTILITY MODEL
In order to solve the defects and shortcomings existing in the prior art, the utility model aims to provide a disposable sputum suction tube; the sputum suction opening of the sputum suction tube body is provided with the hemispherical cutting cover, so that tracheal mucosa can be prevented from being damaged during insertion, and the blockage of the tube opening can be prevented; in addition, the sputum suction port is also provided with a reverse flow prevention valve for preventing the reverse flow of the sputum, so that the sputum can be prevented from flowing back to the respiratory tract of a patient when being pumped out.
For realizing the purpose, the utility model adopts the following technical scheme:
