Technical Field
The utility model relates to a urine cryopreservation tube, which is used for long-term urine storage or long-distance transportation and belongs to the field of medical detection and medical research tools.
Background
Collection and storage of urine is critical to the development of urine testing and urine research, especially long-term storage or long-distance cold chain transport requiring more demanding storage conditions. At present, the urine cryopreservation tube is usually replaced by a serum tube or a centrifugal tube, and the bottoms of the serum tube and the centrifugal tube are usually conical, so that the serum tube and the centrifugal tube are unstable to store and are easy to splash. In addition, the scale marks are unclear, the maximum capacity warning mark line is not striking, and the liquid is easy to overflow due to the expansion of the volume of the liquid when the ultra-low temperature (-80 ℃) storage is carried out, so that the specimen is polluted.
Therefore, a special container for long-term urine storage or long-distance cold chain transportation needs to be designed to prolong the service life of the specimen and ensure the accuracy of urine detection.

The technical problem to be solved by the utility model is as follows: the problem of urine detection accuracy can't be guaranteed to sample pollution that spills easily and spills over in long-term storage or long distance cold chain transportation process to current urine cryopreserving pipe.
In order to solve the problems, the technical scheme of the utility model is to provide a urine cryopreservation tube, which is characterized in that: the urine collecting tube comprises a tube body and a tube cap, wherein one end of the tube body is open, the other end of the tube body is a supporting end, the tube cap is arranged at the open end of the tube body and forms a cavity with the tube body for storing urine, and the bottom of the cavity is conical.
Preferably, be equipped with annular sand grip on the body inner wall, the pipe cap inboard is equipped with the arch, and when the pipe cap cooperated with the body the protruding inboard laminating with annular sand grip just in time forms sealedly.
Preferably, the outer side of the tube body is provided with a marking area for attaching a code or writing a mark.
Preferably, the tube body is provided with scale marks for displaying the storage capacity.
Preferably, a maximum allowable storage capacity line is arranged at least 1cm below the annular convex strip.
Preferably, the support end is cylindrical.
Preferably, the pipe cap and the pipe body are connected through threads.
Preferably, the inner side wall of the tube body is coated with a preservative.
Preferably, the distance between the annular convex strip and the pipe orifice is at least 0.5 cm.
Preferably, the width of the annular convex strip is 1 mm.
Compared with the prior art, the utility model has the beneficial effects that:
(1) the performance of the existing urine cryopreservation tube is improved, and the urine cryopreservation tube is particularly suitable for long-term storage or long-distance cold chain transfer of urine;
(2) the storage stability of the cryopreservation tube is improved, and the functions of specimen treatment and detection are taken into consideration;
(3) the warning mark with the maximum capacity is added, so that the safety of the specimen is protected;
(4) the sealing performance between the tube cap and the tube body is improved, and the accidental loss of the specimen is reduced;
(5) the direct antiseptic that scribbles of body inside wall need not additionally to add, has simplified the operating procedure, has reduced the possibility of polluting.

FIG. 2 is a top view of the tube;
fig. 3 is a schematic view of a cap.
Detailed Description
In order to make the utility model more comprehensible, preferred embodiments are described in detail below with reference to the accompanying drawings.
As shown in figure 1, the urine cryopreservation tube comprises a tube body 1 and a tube cap 2, wherein the top of the tube body 1 is provided with an opening, the bottom of the tube body 1 is a cylindrical support end, external threads are processed at the opening, internal threads are processed on the inner side of the tube cap 2 and are matched with the opening of the tube body 1, a cavity 3 for storing urine is formed between the tube cap 2 and the tube body 1, and the bottom of the cavity 3 is conical.
As shown in fig. 2, an annular protruding strip 11 with a width of 1mm is radially processed at least 1cm above the maximum allowable storage capacity line in the tube body 1, and the distance between the annular protruding strip 11 and the nozzle is at least 0.5 cm. As shown in fig. 3, a circular protrusion 21 is formed in the middle of the inner side of the cap 2, the protrusion 21 is shaped and sized to fit the annular protrusion 11, and the protrusion 21 is just attached to the inner side of the annular protrusion 11 to form a seal when the cap 2 is screwed to the tube 1.
The outer surface of the tube body 1 is provided with a special mark area 12 for code pasting or writing marks, and clear scale marks are marked on the outer surface of the tube body 1 for displaying the storage capacity, and the maximum allowable storage capacity line is a red line. The inner side wall of the tube body 1 is coated with boric acid serving as a preservative.
The bottom of the freezing storage pipe is designed to be cylindrical, so that the stability is greatly improved, and the operation of centrifugation and the like can be completed while the stability is improved by arranging the conical pipe body in the pipe body.
