The specific meaning of the above terms in the present utility model will be understood in specific cases by those of ordinary skill in the art.
Referring to fig. 1 to 3, a sample collection reagent tube according to an embodiment of the present utility model can save sample preservation solution or lysate to a great extent. The reagent tube comprises a tube body 1, a tube cover 2 and a flexible connecting piece 3.
The pipe body 1 comprises a pipe body 11 with a cylindrical shape, a pipe bottom 12 arranged at the lower end of the pipe body 11, a pipe orifice 13 arranged at the upper end of the pipe body 11, a pipe body outer edge 14 arranged at the periphery of the upper end of the pipe body 11 and a sealing film 15 arranged on the pipe orifice 13, wherein an inverted conical inner cavity 16 is arranged in the pipe body 1, and a bending piece 17 is arranged on the side wall of the inner cavity 16. By means of the inverted conical design of the inner cavity 16, when the sampling swab is inserted into the reagent tube, the swab head stained with the sample can be completely immersed by only a small amount of sample preservation solution or lysis solution, so that the sample preservation solution or lysis solution is saved to a great extent. Meanwhile, the diameter of the inner cavity 16 gradually increases from the bottom to the upper part, and when a pipette or a pipette gun is used for loading detection, the pipette or the pipette gun can smoothly enter a reagent tube to suck a sample solution; during manual drop-in sample detection, the problem that the sample solution is accumulated at the bottom 12 of the sampling tube under the action of surface tension and cannot be extruded does not occur. The inner wall of the tube body 1 is a smooth curved surface so as to avoid the sample solution from being adsorbed on the inner wall of the tube body 1.
The bending member 17 is an arcuate rigid plate with a gap, the width of which is adapted to the diameter of the swab handle. The cavity between the chord of the arcuate rigid plate and the side wall of the cavity 16 is larger than the diameter of the pipette or pipette tip for the pipette or pipette to enter the cavity 16. The distance from the bending piece 17 to the bottom of the inner cavity 16 is larger than the distance from the breaking point of the sampling swab to the end of the swab head of the sampling swab, so that the swab head is broken in the inner cavity 16 by the fit clearance of the swab inserted into the inner cavity 16.
The tube body 1 is made of transparent materials, so that the condition in the reagent tube can be observed in real time. The tube bottom 12 is flat bottom and is convenient to be placed on a table top.
In this embodiment, the sealing film 15 is an aluminum plastic composite film, and the sealing film 15 has an extension portion. The aluminum-plastic composite film is heated at high temperature to enable the plastic film to be melted and then cooled and bonded with the pipe orifice 13 so as to realize sealing of the reagent pipe. In use, the sealing film 15 can be easily torn off by the extension. In other embodiments, the sealing film 15 may be made of other materials, which is not limited in particular.
The tube cap 2 comprises a cap body 21 matched with the tube opening 13, a dropper 22 arranged on the cap body 21, a tube cap 23 arranged on the dropper 22 and detachably connected with the dropper 22, a tube cap outer edge 24 arranged on the upper periphery of the cap body 21, and a sealing gasket 25 closely attached under the tube cap outer edge 24. When the reagent tube is used for sampling, the sealing film 15 is torn off, a swab stained with a sample is inserted into the inner cavity 16, the swab head is broken off in the inner cavity 16 through the bending piece 17, and then the tube cover 2 is covered, and the subsequent processing is waited for.
The tube 1 further includes a tube outer rim 14 provided on the outer periphery of the upper end of the tube 11, and the tube outer rim 14, the cap outer rim 24, and the sealing gasket 25 are fitted to each other to tightly seal the reagent tube.
The tube cap 23 is detachably connected with the dropper 22, and when manual drop loading detection is carried out, the tube cap 23 can be detached, and the reagent tube is inverted to extrude the sample solution so as to complete loading monitoring.
The pipe body 1 is connected with the pipe cover 2 through the flexible connecting piece 3, and the use is convenient.
In conclusion, the sample preserving fluid or the lysis solution is contained in the inverted conical inner cavity, and the swab head stained with the sample can be completely immersed only by a small amount of the sample preserving fluid or the lysis solution, so that the sample preserving fluid or the lysis solution is saved to a great extent; meanwhile, the diameter of the inner cavity is gradually increased from the bottom to the upper part, so that the problems that a pipette or a pipette cannot enter a sampling tube and sample solution is accumulated at the bottom of the sampling tube under the action of surface tension in an inverted state and cannot be extruded are effectively avoided.
The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
The above examples illustrate only a few embodiments of the utility model, which are described in detail and are not to be construed as limiting the scope of the utility model. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the utility model, which are all within the scope of the utility model.
