Technical Field
The utility model relates to the technical field of sample collection, in particular to a sampling tube capable of eliminating foam.
Background
For the detection of novel coronaviruses, sample collection and storage are very important. At present, most common sampling tubes for the new coronavirus specimen mostly adopt inactivating tubes such as guanidinium salts, namely, virus preserving fluid in the sampling tubes adopts inactivating agents such as guanidinium salts to inactivate viruses for preservation, and meanwhile, the integrity of virus nucleic acid is not influenced, so that the safety in the process of sample collection and transportation can be greatly improved.
But the guanidine salt can generate a large amount of foam after shaking, and aerosol can be generated instantly when the foam is broken after the sampling tube is opened during detection. And when adopting the pipettor to absorb liquid, the pipettor is every time installed the suction head and is inserted in the sampling pipe, and these foams can be stained with on the pipettor or spatter liquid on the pipettor during the sample, causes cross contamination and laboratory biosafety risk like this easily. Therefore, if a sample is sucked under the condition that foam exists, the probability that the sampling liquid is stained on a glove or a pipettor is very high, and if the sampling liquid is not disinfected immediately, the biological safety risk and the cross contamination risk in a laboratory are very serious, and the new coronas detection result is directly influenced. And the gloves or pipettors are disinfected immediately, so that the detection timeliness is seriously influenced, and particularly, the existence of foam can cause the biological safety, the cross-contamination risk to rise by times and the timeliness to be seriously reduced when the large-scale new crown nucleic acid is detected. Therefore, how to eliminate the foam in the sampling tube becomes a very critical factor.
In order to solve the problems, the scheme is developed accordingly.

Detailed Description
The utility model is explained in more detail below with reference to the figures and examples.
As shown in fig. 1: the utility model provides a sampling pipe that can eliminate foam, includes body 1 and pipe cap 2, has placed virus in the body 1 and has preserved the liquid, is provided with on the inside wall of pipe cap 2 to be used for stretching into 1 inside installation pole 3 of body, and the tip of installation pole 3 is provided with defoaming structure 4 in the top that virus preserved the liquid.
Because virus preservation liquid vibrates and produces a large amount of foams in the transportation, and the foam gathers on the surface of preservation liquid level basically, consequently, this scheme locates the liquid level department of this preservation liquid (flush, preserve a little below of liquid level, top all can) with defoaming structure 4 for when taking off pipe cap 2, defoaming structure 4 breaks away from and preserves the liquid level, and then can eliminate most foam in the twinkling of an eye. Wherein, the defoaming structure 4 can puncture the swelled foam when the liquid level of the preservation liquid is slightly above, and the formation of the foam is avoided to a certain extent.
Specifically, the defoaming structure 4 comprises an annular plate 41 connected to the end of the mounting rod 3 and blades 42 arranged at intervals along the circumferential direction of the mounting rod 3 and connected with the annular plate 41, and defoaming needles 43 extending downwards are arranged on the annular plate 41 and the blades 42.
Because the capacity of the virus preservation solution in the test tube cannot be completely kept consistent, and the page difference exists, the scheme improves the defoaming structure 4 to a certain extent, so that the slightly-changed liquid level of the preservation solution can be better adapted for use.
Referring to fig. 2-3, specifically, the installation rod 3 is connected with the pipe cap 2 by a thread 5, and the thread 5 on the installation rod 3 has a certain margin compared with the thickness of the joint of the thread 5 of the pipe cap 2, so that the defoaming structure 4 can be adjusted to extend into the pipe 1 with a slight liquid level difference. The upper end of the installation rod 3 is provided with an annular rotary block 6 which slides up and down and is arranged outside the pipe cap 2, so that the installation rod 3 can rotate relative to the pipe cap 2 after the pipe cap 2 is fixed and the pipe body 1 is formed.
In order to fix the position of the mounting pipe, a magnet 7 with different magnetism is arranged at the upper end of the pipe cap 2 and the lower end of the rotary block 6 for attracting and fixing, so that the mounting rod 3 connected with the screw thread 5 and the pipe cap 2 are prevented from rotating to cause the position change of the two to influence the defoaming function.
As shown in fig. 4, the sliding manner of the rotary block 6 relative to the mounting rod 3 may be that a vertical groove 8 is provided at the side of the mounting rod 3, and a sliding block 9 with a size matched with the vertical groove 8 is provided at the inner side wall of the rotary block 6 to realize the process. Meanwhile, a fixing block 11 can be arranged at the outermost end of the mounting pipe to prevent the rotary block 6 from being separated from the mounting rod 3.
Further, since the foam in the pipe body 1 is accumulated at the unaffected place, for example, at the edge of the inner wall of the pipe body 1, the size of the annular plate 41 is adapted to the radial size of the inner cavity of the pipe body 1 as much as possible, but there is a problem in that if a slight shift in the vertical direction occurs when the cap 2 is removed, a large frictional force is easily generated, resulting in difficulty in removal. Consequently, this scheme sets up the size of annular plate 41 and is less than in the radial size of 1 inner chamber of body, at the circumference ring cloth water conservancy diversion piece 10 of annular plate 41 simultaneously, further carries out the defoaming to the border position and handles.
In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the utility model. The technical scope of the present invention is not limited to the content of the specification, and the protection scope must be determined by the scope of the claims.
