Detailed Description

Hereinafter, the flip-type sampling tube of the present utility model will be described in detail with reference to the accompanying drawings.

The flip-type sampling tube as shown in fig. 1-3 comprises a tube body 1, a tube cap 2 and an inner cover 3; the pipe body 1 is a cylindrical barrel without a cover, the upper part of the pipe body 1 is provided with an external thread 11, the pipe cap 2 is a cylindrical barrel, the inner side surface of the pipe cap 2 is provided with an internal thread 21, the internal thread 21 is matched with the external thread 11, and the inner cover 3 comprises a left cover 31 and a right cover 32; the left cover 31 and the right cover 32 are of semi-cylindrical structures, the left cover 31 is fixed on the upper surface of the tube body 1, the left cover 31 is connected with the right cover 32 through the turnover connecting piece 33, the connecting piece 33 is square and is fixed on the upper surface of the joint of the left cover 31 and the right cover 32, the right cover 32 can be opened and closed along with the turnover of the connecting piece 33, and can be opened and closed only by one hand during use, so that medical staff can conveniently open and close the right cover 32 in the sample collection process and can close the right cover 32 at any time to prevent virus preservation liquid from volatilizing, and the opened right cover 32 is not dropped due to the connection and fixation with the connecting piece 33, so that the nucleic acid detection process only needs single operation, manpower is reduced, the nucleic acid detection process is more flexible and convenient, and the portability of the sampling tube is improved.

Preferably, the lower surface of the right cover 32 is provided with a semicircular fixing ring 34, the diameter of the fixing ring 34 is matched with the diameter of the inner surface of the tube body 1, and when the medical staff presses the right cover 32 to close, the sealing of the sampling tube is tighter through the mutual extrusion between the fixing ring 34 and the inner surface of the tube body 1, so that the right cover 32 cannot be opened due to collision when the sampling tube is carelessly poured.

Preferably, the lower surface of the right cover 32 is provided with the breaking part 35, the breaking part 35 is in a circular arc structure and is tightly attached to the fixing ring 34, and the breaking part 35 assists medical staff in breaking the cotton swab at the front end of the pharyngeal swab, so that the cotton swab is more labor-saving and convenient to break, and meanwhile, the medical staff is prevented from damaging the fixing ring 34 through the auxiliary breaking of the fixing ring 34, so that the sampling tube is not tightly sealed, and virus preservation liquid volatilizes even flows out of the virus preservation liquid.

Preferably, the cambered surface edge of the right cover 32 extends outwards to form an opening ring 36, the cambered surfaces of the right cover 32 extend outwards, the opening ring 36 can be pushed in different directions when a medical staff opens and closes the right cover 32 by one hand, and the medical staff can open the right cover 32 more conveniently only by pushing the opening ring 36 upwards.

Preferably, the square groove 22 is longitudinally arranged at the center of the inner bottom surface of the pipe cap 2, the shape and the size of the groove 22 are matched with those of the connecting piece 33, in order to prevent collision of the sampling pipe and leakage of virus preservation liquid in the sampling pipe in the transportation process before and after sampling, after the groove 22 is completely overlapped with the connecting piece 33, the inner bottom surface of the pipe cap 2 is completely overlapped and sealed with the upper surfaces of the left cover 31 and the right cover 32, and the right cover 32 is prevented from being opened due to collision so as to enable the virus preservation liquid to flow out.

Preferably, the outer surface of the pipe cap 2 is provided with anti-skid lines, and the outer surface of the general pipe cap 2 is vertically and uniformly provided with protrusions, so that the friction force of the pipe cap 2 is increased, and the pipe cap 2 is convenient for medical staff to unscrew.

In this embodiment, when using the sampling tube, the medical staff unscrews the cap 2 first, uses the pharyngeal swab with one hand to sample, holds the tube body 1 with the other hand, pushes the opening ring 36 upwards with the thumb, then opens the right cover 32 upwards and turns over around the connecting piece 33, then puts the pharyngeal swab into the sampling tube, then closes the right cover 32, breaks the cotton swab head into the sampling tube through the breaking part 35, finally presses the right cover 32 to enable the fixing ring 34 to squeeze the sealing sampling tube with the inner surface of the tube body 1, and tightens the cap 2 to enable the bottom surface of the groove 22 to be attached to the upper surface of the connecting piece 33.

The foregoing description is only of the preferred embodiments of the present application and is not intended to limit the same, but rather, various modifications and variations may be made by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
