Description
Technical field
The invention belongs to the field of medical instrument technology, and in particular to one kind is exclusively used in pretreatment unit before Sputum culturing.
Background technique
Phlegm is the secretion of human respiratory tract, it be by the movement of bronchus ciliary movement epithelial cilia, from lung to
The upper respiratory tract pushes, finally, the normal cough reflex by people is excreted from intratracheal expectoration, normal person's phlegm is seldom, only
The a small amount of mucus for keeping respiratory tract wet and secreting.But when people sucks the nocuousness such as irritative gas, dust, pathogenic bacteria, virus
When microorganism, the upper respiratory tract may be inflamed or disease occurs for lung, and respiratory tract will secrete increase, and amount of expectoration will
Increase, and the property of phlegm can also change, and can become yellowish purulent sputum by viscous phlegm.
Sputum sample is that clinical microbiology examines most common sample, with the progress of science and technology, medical level
It increases, Medical scientists have invented more and more various certain inspection method, and many diseases can be by draining body
The inspection of object ingredient and find out, Sputum culturing, be exactly a kind of new inspection method, Sputum culturing, be primarily used to check pulmonary tuberculosis
Disease.
Often there is patient to need to carry out sputum chemical examination inside hospital, there are many factor for influencing bacteriologic test result reliability,
Acquisition, utilization including sample, are separately cultured technology and methods and identification of means.Wherein people often only pay attention to culture identification
Method, and the acquisition method of sample and the quality of sample are had ignored, it is sputum specimen the problem of most serious at present.Therefore, phlegm mark
Originally the pretreatment before Sputum culturing, it is most important for whether Sputum culturing succeeds.Some hospitals are using salt washing phlegm or with 1%
37 DEG C of 90min processing of trypsase, make phlegm homogenize, and in contrast, conventional method is time-consuming, cumbersome, are unfavorable for clinical real
Border work, and sputum specimen only wash it is not broken or broken not enough completely, the Oral normal flora of miscellaneous band is not easy to be disappeared in sample
It removes, the pathogenic bacteria being wrapped in dense phlegm are not separated adequately, and the culture of pathogenic bacteria is contaminated, and are not able to satisfy now
Actual demand much pretreated for Sputum culturing.
Summary of the invention
Against the above technical problems, the present invention provides one kind and is exclusively used in pretreatment unit before Sputum culturing, and phlegm mark can be improved
