Description
Technical Field
The utility model relates to a tuberculosis patient sample sampling field especially relates to a tuberculosis patient sputum collector.
Background
Mycobacterium tuberculosis (m. tuberculosis), commonly known as mycobacterium tuberculosis, is the causative agent of tuberculosis. It can invade all organs of the body, but pulmonary tuberculosis is the most common. Tuberculosis remains an important infectious disease to date.
The current methods for detecting tubercle bacillus mainly include etiological method, immunological method and molecular biological method. The etiology detection is the only tuberculosis diagnosis method at present, and the etiology methods mainly comprise two methods: one, sputum smear method. The method is the most basic bacteriological examination method used in tuberculosis laboratories all over the world, and has the advantages of rapidness, convenience, low cost and the like. The sputum smear method is a quick, cheap and feasible method for clinical diagnosis. And secondly, a sputum culture method. The conventional culture method for the tubercle bacillus has the advantages of higher sensitivity, specificity and accuracy, is a reliable method for identifying dead and live bacteria, is an irreplaceable method for detecting the live bacteria at present, and is also a main monitoring index of chemotherapy reaction; the disadvantages are that the culture time is too long, the result can be reported after 4-8 weeks, the new rapid culture method has expensive instruments, needs to import liquid culture medium, has high cost and is not beneficial to popularization.
At present, the clinical sputum smear detection mode is that after a sputum sample is obtained, a part of the sputum sample is directly smeared and stained by a staining microscope for detection, and due to the fact that the sputum sample is large in viscous substances and poor in fluidity, contains cells exfoliated from a human body and is limited in the number of possible tubercle bacillus, all bacteria in the sputum cannot be effectively collected on a glass sheet by the method. Therefore, if the sputum is liquefied by adopting a corresponding method or reagent to release the tubercle bacillus and simultaneously the human exfoliative cells in the sputum are cracked, all the tubercle bacillus can be collected by simple centrifugal treatment for flaking. Not only increases the bacterial visual field density under a microscope, but also eliminates the interference of mucus and human exfoliated cells, and greatly improves the diagnosis sensitivity. At present, sputum of a patient is collected firstly and then returned to a laboratory for treatment, but problems are many, aerosol splashes everywhere when the patient expectorates, and the pollution to personnel collecting samples and the environment is very serious; the second sputum is sometimes insufficient, and after returning to a laboratory, an operator finds that the second sputum needs to be returned for re-sampling; the third sputum receiving flask can not handle the sputum, so collect the sputum that returns and need just handle immediately, still need transfer to the centrifuging tube in laboratory in the sputum receiving flask in suitable containers such as centrifuging tube, the more possibility of polluting of operation is big more, but also increase work load.
SUMMERY OF THE UTILITY MODEL

In order to achieve the above objects and other related objects, the utility model provides a tuberculosis patient sputum collector, a serial communication port, tuberculosis patient sputum collector includes: the device comprises a sampling cover, a sampling port, a sampling funnel, a flow guide pipe, a sample collecting pipe, a collecting pipe cover and sputum treatment liquid; the sputum treatment solution is contained in the sample collection tube; a threaded interface is arranged on the inner side of the sampling cover; the outer side of the upper end of the sampling port is provided with a thread; the sampling cover is connected with the sampling port through threads; the lower end of the sampling port is connected with the upper end of the sampling funnel; the lower end of the sampling funnel is divided into an inner layer and an outer layer in an extending mode, the inner layer is directly connected with the flow guide pipe, and a threaded connector is arranged on the inner side of the lower end of the outer layer; the guide pipe is arranged along the side wall of the sample collecting pipe, and the outlet of the guide pipe is positioned at the lower end of the sample collecting pipe; the outlet of the draft tube is immersed below the liquid level of the sputum treatment liquid; the outer side of the top end of the sample collecting pipe is provided with a threaded interface; the outer layer of the lower end of the sampling funnel is connected with the sample collecting pipe through threads; the collecting tube cover is internally provided with threads and can be connected with a sample collecting tube through the threads;
preferably, the sampling port is cylindrical, and the diameter of the upper end of the sampling port is 4.5-8cm and is slightly larger than the normal caliber of a human body; the height of the sampling port is 2-5 cm; the size of the sample collecting tube is the same as that of a conventional 15ml centrifugal tube, and the wall of the sample collecting tube is written with corresponding capacity; the sputum treatment fluid is 5-8 ml; the sputum treatment fluid is sterile sputum treatment fluid commonly used by tubercle bacillus in the market; the diameter of the flow guide pipe is 0.3-1 cm;
preferably, the inner diameter of the sampling cover is equal to the outer diameter of the sampling port; the inner diameter of the collecting tube cover is equal to the outer diameter of the sample collecting tube, and the outer diameter of the sample collecting tube is equal to the inner diameter of the bottom of the sampling funnel.
As mentioned above, the sputum collector for tuberculosis patients of the utility model has obvious advantages when in use, firstly, when the patient expectorates sputum, the oral part is aligned with the sampling port to directly collect the sputum, the sampling port not only seals the oral part of the patient, the sputum can not splash around to pollute the environment, but also the sampling port is deeper, the lips of the patient can not touch the sputum collector for tuberculosis patients, and the discomfort of the patient is reduced; secondly, the diversion pipe designed by the utility model can make the sputum directly slide in the sputum treatment fluid, the sputum cannot be wasted, and the sputum cannot be splashed everywhere to pollute the sputum collector of the tuberculosis patient; the third sputum treatment solution is used for pretreating the sputum, and the sputum can be placed for a period of time even if the sputum cannot be immediately treated in time; the sample collecting pipe in the fourth tuberculosis patient sputum collector is the same size with the common 15ml centrifuging tube in laboratory, consequently after gathering the sputum, if environmental condition does not allow, can cover the sampling lid back, takes tuberculosis patient sputum collector back to the laboratory, covers sampling lid, sample connection, sampling funnel, honeycomb duct again and takes off disinfection processing, covers the collecting tube lid, can not the polluted environment also need carry out disinfection processing at the outdoor environment of laboratory to the utensil that pollutes.
