Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in FIGS. 1 and 2, the nucleic acid collection tube of the present embodiment includes a tube body 1, a first tube cap 2 and a second tube cap 3, wherein one end of the tube body 1 is open, the other end is closed, and both the first tube cap 2 and the second tube cap 3 can be detachably connected to the open end of the tube body 1. Specifically, the open end of the pipe body 1 is provided with a first external thread 4, the first pipe cover 2 and the second pipe cover 3 are both provided with internal threads, and the first pipe cover 2 or the second pipe cover 3 can be connected to the open end of the pipe body 1 through threads. Thus, one of the first cap 2 and the second cap 3 can be selectively attached to the open end of the tubular body 1.

The closed end of the pipe body 1 is provided with a second external thread 5, the second pipe cover 3 can be connected to the closed end of the pipe body 1 through the thread, and when the product is not in use at the initial stage, the second pipe cover 3 is connected with the pipe body 1 through the second external thread 5, so that the pollution to the inner side of the second pipe cover 3 can be avoided.

The first cap 2 can be used in the process of collecting nucleic acid, and the second cap 3 can be used after the collection, wherein the first cap 2 is provided with an inlet 6 for inserting a swab, the inlet 6 is provided with a sliding cover 7, and the sliding cover 7 can slide to open or close the inlet 6, so as to facilitate the collection of the swab by the inlet 6.

In addition, in order to restrict the sliding cover 7 from moving only in a straight line to open or close the insertion opening 6, the upper end of the first tube cover 2 is provided with sliding grooves 8 at both sides of the insertion opening 6, and both sides of the sliding cover 7 are provided with sliding blocks 9, the sliding blocks 9 being slidably provided on the sliding grooves 8. Typically, the chute 8 extends in a horizontal direction. In addition, the upper end of the slide cover 7 is provided with an anti-slip pattern 12 so that the slide cover 7 is not easily slipped when pushed.

In this embodiment, one end of the sliding cover 7 is provided with a clamping block 10, and the clamping block 10 includes two blocks arranged at intervals. The upper end of the first tube cover 2 is provided with an insertion hole 11, the insertion hole 11 is positioned at one end of the sliding chute 8, and when the sliding cover 7 slides to shield the placing inlet 6, the clamping block 10 is inserted into the insertion hole 11 to fix the position of the sliding cover 7. This arrangement has two advantages, the first is that the holding block 10 can be used to hold the rod of the swab to facilitate breaking off and storing the sample, and the second is that the position of the sliding cover 7 can be fixed by the cooperation of the holding block 10 and the insertion hole 11.

When collecting nucleic acid, at first with first tube cap 2 through first external screw thread 4 connection to the opening of body 1, remove sliding cover 7 and make put into mouth 6 and open completely, then, push sliding cover 7 again after stretching into the swab for the pole portion of swab presss from both sides between two grip blocks 10, so that break off the swab with the fingers and thumb, remove sliding cover 7 again at last, shelter from totally and cover and put into mouth 6, and utilize grip block 10 and jack 11 cooperation fixed. The above operations are repeated to collect a plurality of nucleic acid samples, and after the collection is completed, the first cap 2 can be removed from the tube body 1 and replaced with the second cap 3.

The above description is only exemplary of the present invention and should not be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
