It should be noted that like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, it does not require further discussion in subsequent drawings.

[0028] Reference is made below to Figures 1 to 4 , for a further description of the present invention:

[0029] A PCR tube annular bracket, comprising:

[0030] A bracket body 1, which is integrally circular, and a plurality of test tube holes 2 are distributed in a circular shape on the bracket body 1, and each test tube hole 2 can hold a PCR tube 3.

[0031] In this embodiment, the test tube hole 2 and the PCR tube 3 are assembled by an interference fit method, and the interference amount of the interference fit is 0.3 mm to 0.5 mm.

[0032] After testing, an interference amount of 0.3 mm to 0.5 mm is an ideal range, which can ensure that the PCR tube 3 can be easily inserted into the test tube hole 2, and can also ensure that the PCR tube can be closely fitted after being inserted into the test tube hole 2, relatively becoming a whole, and achieving the most ideal fitting effect.

[0033] In this embodiment, the diameter range of the test tube hole 2 is 6 mm to 15 mm.

[0034] Generally, the capacity of the PCR tube 3 is between 0.2 ml and 2 ml, and the diameter is between 6 mm and 11 mm. By setting the diameter of the test tube hole 2 between 6 mm and 15 mm according to different usage requirements, different specifications of the PCR tube 3 can be well adapted.

[0035] In this embodiment, the number of test tube holes 2 is 8. Currently, the more common ones are single-tube or linear 8-connected tubes. Setting the number of test tube holes 2 to 8 can better cooperate with the existing PCR tube 3 consumables and achieve fast operation.

[0036] In a preferred embodiment, the material of the bracket body 1 is an EVA foam board, and the hardness of the EVA foam board is 45 degrees.

[0037] Using an EVA foam board with a hardness of 45 degrees can achieve the best use experience and enable a better interference fit effect between the EVA foam board and the PCR tube 3. During actual use, foam boards of other hardnesses can also be selected according to the usage needs to achieve the best use effect.

[0038] In an alternative embodiment, the material of the bracket body 1 is silicone. Because silicone has a certain elasticity and a certain strength, using silicone can also achieve an interference fit with the PCR tube 3 and can achieve a use effect similar to that of the EVA foam board.

[0039] In an alternative embodiment, the material of the bracket body 1 is rubber. Rubber can also meet the usage requirements in terms of elasticity and strength, achieve an interference fit with the PCR tube 3, and achieve a relatively ideal use effect.

[0040] According to another aspect of the present application, a constant-temperature nucleic acid amplification analyzer is provided. The constant-temperature nucleic acid amplification analyzer includes the above-mentioned PCR tube circular bracket.

[0041] The constant-temperature nucleic acid amplification analyzer including the PCR tube circular bracket can cooperate with the PCR tube circular bracket. During use, the PCR tube circular bracket can be placed into the constant-temperature nucleic acid amplification analyzer together with the PCR tube 3. There is no need to take out the PCR tube circular bracket separately, and the nucleic acid analysis test can be directly carried out. The use process is simple and fast, saving operation steps.

[0042] Currently, the detection holes of some instruments on the market are arranged in a circular ring and cannot directly use linear 8-connected tubes. It is necessary to cut the 8-connected tube or use single tubes. When performing the test operation, the consumables need to be placed one by one in sequence, and the operation is cumbersome and time-consuming.

[0043] By using the PCR tube circular bracket and the constant-temperature nucleic acid amplification analyzer in the present application, the operation steps can be reduced and the operation time can be effectively saved.

[0044] The installation operation steps are as follows:

[0045] S1. Install the PCR single tube onto the PCR tube foam bracket. The PCR single tube and the holes on the PCR tube foam bracket form an interference fit to make them an integral body.

[0046] After the reagent preparation is completed, the PCR tube foam holder and the PCR single tube are taken as a whole and directly placed into the constant temperature nucleic acid amplification analyzer for nucleic acid detection.

[0047] The above steps are simple and fast, and compared with the previous methods, the efficiency is effectively improved.

[0048] In addition, the PCR single tube is installed on the PCR tube foam holder. The foam holder with the PCR single tube installed can be independently placed on the desktop, acting as a test tube rack, facilitating the preparation of various reagents. There is no need to put the single tubes one by one multiple times, which simplifies the manual operation. Moreover, the order is determined, ensuring that the loading order of the reagent tubes will not be disordered and guaranteeing the accuracy of nucleic acid detection.

[0049] The PCR tube foam holder is used in cooperation with the constant temperature nucleic acid amplification analyzer as an accessory, which simplifies the manual operation in the experiment, improves the nucleic acid detection efficiency, guarantees the accuracy of nucleic acid detection, and at the same time saves the cost of separately opening the circular 8-tube mold.

[0050] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by orientation words such as "front, rear, upper, lower, left, right", "horizontal, vertical, perpendicular, horizontal" and "top, bottom", etc. is usually based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description. Without contrary explanation, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, it should not be construed as limiting the protection scope of the present utility model; the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0051] The above is only the preferred embodiment of the present utility model and is not used to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
