Description
Technical Field
The utility model belongs to the technical field of the microorganism collection utensil, specifically speaking are supporting stopper of swab sampling pipe.
Background
The detection of nucleic acids of infectious diseases in PCR laboratory testing projects dominates, and many of these projects use "disposable sampling swabs" (abbreviated as "swabs") for specimen collection. The swab consists of two parts, one is a sealed tube for storing the sample and the other is a cotton swab for collecting the sample.
The swab is used for wiping and smearing a sampling part to serve as an original sample, during subsequent experiment operation, normal saline needs to be added into the tube and then vibrated, so that pathogen components on the cotton swab are eluted, and an experimenter uses the eluted normal saline to perform pathogen nucleic acid detection.
But because the swab pipe is overlength, the application of sample rifle can not stretch into the swab pipe and take a sample, can only incline 95 degrees and make the sample flow to mouth of pipe footpath department just can the imbibition, the application of sample can lead to having following several inconveniences or risks like this:
1. because the experimental projects made by the subject are subjected to an amplification procedure, the 'pollution prevention' is most important in the whole experimental process, and when the sample liquid flows into the caliber of the tube and flows out, the sample liquid is easy to overflow, so that the sample liquid in the biological safety cabinet is easy to leak, and the risk of pollution is generated to a certain extent;
2. if the samples overflow, air pollution is generated if the samples are not processed in time, the whole two areas need to be ventilated, disinfected and cleaned on peripheral table tops, so that all experiments cannot be smoothly carried out;
3. the periphery of the diameter wall of the tube opening is wiped by paper towels when sample adding is carried out every time, so that experiment workers must replace gloves, and a large amount of time is wasted for processing the pollution possibly caused by the glove replacement.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
The swab sampling tube is fitted with a stopper as shown in FIGS. 1-2. Including transparent bottle stopper 1, 1 covers on test tube 2 of bottle stopper, be equipped with a first cone 3 and a transparent second cone 4 in the bottle stopper 1, the central line and the test tube 2 level of a first cone 3 and a second cone 4, a first cone 3 fixed mounting in the bottle stopper 1, the annular third rubber pad of periphery fixed mounting of a second cone 4 11, the cooperation of the big bore contact of a first cone 3 and a second cone 4, the outer ring diameter ratio of third rubber pad 11 is 1mm big than the inner ring diameter of bottle stopper 1. A third conical cylinder 12 is fixedly arranged in the bottle stopper 1, the inner diameter of the third conical cylinder 12 is consistent with that of the test tube 2, and the small caliber of the third conical cylinder 12 is opposite to that of the first conical cylinder 3. The inner wall fixed mounting annular first rubber pad 5 of 2 one ends of test tube is close to bottle plug 1, first rubber pad 5 and the cooperation of 2 contacts of test tube. The top of bottle plug 1 is equipped with test tube cap 6, and test tube cap 6 includes inserted bar 7 and baffle 8, and inserted bar 7 and baffle 8 fixed connection, the periphery fixed connection of inserted bar 7 and the 1 contact complex second rubber pad 9 of bottle plug, fixed mounting handle 10 on the baffle 8.
In this device, the test tube 2 cover is at the lower extreme of bottle plug 1, because the first rubber pad of lower extreme inner wall fixed mounting 5 of bottle plug 1, the outer wall contact cooperation of first rubber pad 5 and bottle plug 1, consequently, in close contact with as an organic whole between test tube 2 and the bottle plug 1.
When this device does not use, inserted bar 7 on the test tube cap 6 is inserted in bottle plug 1, thereby can protect the leakproofness of 1 department of bottle plug, prevent that the liquid in the test tube 2 from volatilizing to the external world through bottle plug 1, baffle 8 can block that inserted bar 7 is whole to insert in bottle plug 1 simultaneously, and the second rubber pad 9 and the 1 contact cooperation of bottle plug of the periphery fixed mounting of inserted bar 7, the leakproofness of inserted bar 7 and bottle plug 1 can further be increased in the cooperation of second rubber pad 9 and the 1 contact of bottle plug, prevent that the liquid in the test tube 2 from volatilizing through bottle plug 1 and 7 clearance departments of inserted bar.
This device is when using, extract test tube cap 6 from bottle plug 1, then transversely place test tube 2, because test tube 2 is when violently putting, the bottom surface inner wall when the small-bore of first cone 3 and test tube 2 are violently put forms certain difference in height, consequently first cone 3 can guarantee test tube 2 when violently putting, liquid in test tube 2 can not all flow out from test tube 2, and simultaneously, when test tube 2 is violently put, can form certain space between two big bores of second cone 4 and first cone 3, consequently, the liquid that flows out can exist temporarily in this space in the test tube 2, and then make things convenient for the application of sample rifle to sample, consequently, first cone 3 and second cone 4's combined action can effectually prevent that liquid from appearing overflowing when test tube 2 flows out from test tube 2. And when the installation of third conical cylinder 12 can guarantee that test tube 2 is horizontal, the liquid in the test tube 2 can flow in the small-bore of first conical cylinder 3 through third conical cylinder 12 in, and then prevents that the liquid in the test tube 2 from piling up between first conical cylinder 3 and test tube 2.
The use of this device can prevent effectively that test tube 2 from putting transversely, and the liquid in the test tube 2 is excessive to can prevent to leak and then prevent the air pollution who causes because of the excessive interior sample of biological safety cabinet that causes of liquid. Simultaneously, because the interior liquid of test tube 2 can not be excessive, thereby the staff need not to wipe the pipe orifice footpath wall around with the paper towel at every turn application of sample thereby the staff need not change gloves often, further save time and physical power that the staff consumed.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
