Technical Field

[0001] The utility model relates to the technical field of biomedical consumables, in particular to a cryopreservation tube for storing blood clots. Background Art

[0002] A blood clot, whose full name is blood clot, refers to the phenomenon that red blood cells in the blood aggregate into lumps under the action of chemical reagents, toxic substances, biological substances, temperature, etc. After coagulation, the blood changes from a sol state to a gel state of a blood clot. For example, under the action of the fibrin network, red blood cells are gathered together to form a blood clot.

[0003] The blood clot is in gel form. The existing blood clot freezing procedure is to use a glass rod to gently crush the blood clot and then use a medicine spoon to dispense it into ordinary cryopreservation tubes. In this process, the glass rod is mixed and the medicine spoon is dispensed, which takes a long time. In addition, when a large number of samples need to be frozen, there is a shortage of glass rods and medicine spoons. The general treatment method is to directly rinse the glass rods and medicine spoons and recycle them. This process is time-consuming and laborious. There is also a situation where the glass rods and medicine spoons are not completely cleaned, resulting in the risk of cross-contamination between samples, which in turn causes inaccurate experimental results and waste of biological samples in the later stage. Utility Model Content

DETAILED DESCRIPTION

[0022] The following is a further clear and complete description of the technical features of the technical solution provided by the utility model in conjunction with the specific implementation methods. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0023] Example 1

[0024] This embodiment provides a cryotube for storing blood clots. The cryotube is an internally rotating cryotube, and its structural schematic diagram is shown in FIG. Figure 1 As shown, the cryopreservation tube includes a tube body 1, a tube cover 2, a cutting piece 3 and a supporting piece 4; the cutting piece 3 is used to cut off blood clots, and the cutting piece 3 is connected to the inner wall of the tube body 1; an opening is provided on the top of the tube body 1, and a accommodating cavity 5 is provided inside the tube body 1; one end of the supporting piece 4 is fixedly connected to the tube cover 2, and the other end of the supporting piece 4 extends into the accommodating cavity 5 of the tube body 1.

[0025] The cryopreservation tube provided in this embodiment has a cutting piece connected to the inner wall of the tube body and a supporting piece fixedly connected to the tube cover. When pouring the blood clot from the blood collection tube into the cryopreservation tube for packaging and storage, the cutting piece can cut off the blood clot, and the supporting piece fixedly connected to the middle part of the tube cover can assist the cutting piece in cutting off the blood clot and then packaging it into the cryopreservation tube, which is convenient for one-handed operation to store the blood clot. Compared with the traditional cryopreservation tube for packaging and storing blood clots, the cryopreservation tube provided in this embodiment does not need to use a glass rod to crush the blood clot and a medicine spoon to package and store the blood clot. There is no need to clean the glass rod and the medicine spoon, which saves time and avoids the risk of cross-contamination between blood clot samples due to unclean cleaning of the glass rod and the medicine spoon, as well as the problem of incorrect experimental results and waste of biological samples in the later stage. Moreover, when there are a large number of blood clots, compared with directly storing a large number of blood clots in the same cryopreservation tube, using the cryopreservation tube provided by the utility model to divide and store the blood clots is convenient for subsequent experiments and can prevent the blood clot samples in the same cryopreservation tube from being degraded and unusable due to repeated freezing and thawing.

[0026] Further, see Figure 2The schematic diagram of the structure of the cutting piece in the internally rotating cryogenic tube rotating counterclockwise and the top view of the tube mouth of the cryogenic tube are shown. In this embodiment, one end of the cutting piece 3 is hinged to the inner wall of the tube body 1 through the hinge shaft 6, and the other end of the cutting piece 3 extends out of the tube body 1, and the hinge shaft 6 is parallel to the opening direction of the tube body 1, and the diameter of the tube body 1 is greater than the length of the cutting piece 3.

[0027] On the basis of the above structure, when using the cryopreservation tube of the utility model, during use, the carrier 4 can be used to carry the blood clot and the blood clot can be cut off by using the cutting piece 3 that extends out of one end of the tube body 1, and then the carrier 4 carrying the blood clot can be extended into the accommodating cavity 5 of the tube body 1 and the blood clot can be packed into the tube body 1. Since the length of the cutting piece 3 is smaller than the diameter of the tube body 1 and one end of the cutting piece 3 is hinged to the inner wall of the tube body 1 through the hinge shaft 6, after the blood clot is packed into the tube body 1, the carrier 4 can be used to rotate the end of the cutting piece 3 that extends out of the tube body 1 counterclockwise along the hinge shaft 6 so that the cutting piece 3 is flipped into the accommodating cavity 5 of the tube body 1 and is parallel to the opening direction of the tube body 1 or folded to the inner wall of the tube body 1. The above arrangement can ensure that the carrier 4 will not extend out of the tube body 1 after cutting off the blood clot, and will not affect the sealing between the tube cover 2 and the tube body 1 of the cryopreservation tube.

[0028] Figure 2 The cutting member 3 shown is a top view when the end of the cutting member 3 extending out of the tube body 1 is flipped along the hinge axis 6 into the accommodating cavity 5 of the tube body 1 by the supporting member 4 and parallel to the plane direction of the tube mouth of the tube body 1.

[0029] Furthermore, the tube cover 2 includes a tube cap 7 and a connecting column 8 , and the outer wall of the connecting column 8 is connected to the inner wall of the tube body 1 via a thread 9 .

[0030] Furthermore, the outer wall of the pipe cap 7 is provided with anti-slip grooves 10 .

[0031] By providing the anti-slip grooves 10 on the outer wall of the tube cap 7, the risk of the tube cover 2 slipping or falling off due to the smooth outer wall of the tube cap 7 when the cryotube is in use can be reduced.

[0032] Furthermore, a sealing member 11 is provided on the tube cover 2 , and the sealing member 11 is used to seal the tube cover 2 and the tube body 1 .

[0033] By providing a sealing member 11, such as a rubber sealing ring, on the tube cover 2, when the tube cover 2 is connected to the tube body 1 by rotation, the sealing between the tube cover 2 and the tube body 1 can be improved, thereby reducing the risk of blood clots or liquid seeping out of the cryopreservation tube during storage or transfer.

[0034] Furthermore, a slot 12 is provided on the tube cover 2 .

[0035] When using external testing equipment to test the sample in the cryotube, the tube cover 2 can be provided with a card slot 12 whose structure can match the structure of the manipulator of the external testing equipment, so as to facilitate automated sample injection testing.

[0036] Furthermore, the tube cover 2 is connected to the tube body 1 via a connecting strip 13 .

[0037] The tube cover 2 is connected to the tube body 1 by the connecting belt 13, so that the tube cover 2 can be prevented from being lost during the use of the cryopreservation tube.

[0038] Furthermore, the cryotube also includes a base 14, which is used to support the tube body 1, and the base 14 is detachably connected to the tube body 1.

[0039] By providing a base 14 for supporting the tube body 1 at the bottom of the cryotube, there is no need to hold the tube body 1 of the cryotube in hand during the operation of packaging and storing the blood clot, so that the cryotube can stand stably on the laboratory table, which is more convenient to operate.

[0040] Furthermore, the outer wall of the tube body 1 is provided with a capacity scale 15 , and the bottom of the base 14 is provided with an identification QR code 16 .

[0041] Providing a volume readable mark 15 on the outer wall of the tube body 1 of the cryotube is beneficial for quantitative packaging and storage of blood clots, while providing an identification QR code at the bottom of the base 14 can facilitate the distinction between different biological samples and avoid confusion.

Compared with Embodiment 1, the difference is that the cryopreservation tube provided in this embodiment is an externally rotating cryopreservation tube, the inner wall of the tube cover 2 is connected to the outer wall of the tube body 1 through a thread 9, and the outer wall of the tube cover 2 is provided with an anti-slip pattern 10. The structural diagram thereof is shown in FIG. Figure 3 Except for the above differences, other structures of the cryopreservation tube provided in this embodiment are strictly consistent with those in Example 1.

[0044] The above embodiments are only used to illustrate the technical solution of the utility model rather than to limit the protection scope of the utility model. Although the utility model is described in detail with reference to the above embodiments, ordinary technicians in the relevant field should understand that the technical solution of the utility model can be modified or replaced by equivalents, but these modifications or replacements are all within the protection scope of the utility model.
