Technical Field

The invention belongs to the technical field of medical equipment, and particularly relates to a nondestructive sputum aspirator.

Background

In the treatment of patients by medical institutions, sputum aspiration is one of the current common medical procedures, and the main purpose is to keep the respiratory tract of the patient clear and to extract sputum for medical examination, so a sputum aspiration tube is also one of the most common medical instruments.

Experiments according to the fluid mechanics principle prove that the flow rates of the fluid at various points of the cross section of the pipeline are obviously different, the flow rate of the center of the pipeline is the fastest, the flow rate is slower the farther from the center, and the flow rate at the pipeline wall is zero. When medical staff sucks phlegm for patients, viscous phlegm blocks are polymers of pathogenic microorganisms such as bacteria, viruses, fungi and the like and shed human cells. These are also the most valuable parts of sputum sample analysis. Through detection and analysis of the substances, doctors can accurately judge the pathogenic factors, disease types, disease degrees, medicines and the like of patients after healing. The reliability and the value of sputum examination in respiratory diseases are far greater than those of CT, nuclear magnetism and other imaging examination means.

The sputum aspirator tube in the prior art cannot effectively collect the substances. In the sputum sucking operation, some sputum blocks are adhered to the wall of the sputum sucking pipe, so that the problem that the sputum sucking pipe cannot be smoothly sucked out exists, and even the phenomenon that the sputum sucking pipe is blocked occurs in severe cases.
