Description

A sputum suction tube capable of accurate sampling

technical field

The utility model belongs to the technical field of medical instruments, in particular to a sputum suction tube capable of accurate sampling.

Background technique

Sputum suction refers to a method of sucking out respiratory secretions through the oral cavity, nasal cavity, and artificial airway (tracheotomy) to keep the airway unobstructed and prevent complications such as aspiration pneumonia, atelectasis, and suffocation. It is suitable for comatose patients, patients with a lot of sputum that may cause suffocation, need intratracheal administration, inject contrast medium or dilute sputum. Patients with tracheal intubation or tracheotomy cannot actively spit, and patients often need to suck sputum when spitting. There are also patients with lung infection, who also need to suck sputum when spitting. After the tube is inserted into the trachea, suction is performed using negative pressure.

In clinical medicine, the sampling test of patient's sputum is of great significance, and the sputum sampling of the prior art is mostly to insert the sputum suction tube into the patient and suck out the sputum as the test sample. The liquid is relatively thin and cannot accurately reflect the patient's physical condition, so there will naturally be certain deviations in the doctor's diagnosis of the condition based on the test results.
