Embodiment 1

[0046] like figure 1 As shown, a reagent tube includes a tube body 10 and a tube cover 20; a sealing member is provided in the contact area between the tube cover and the tube body, so that the tube cover seals the tube body, wherein the tube The inner wall of the cover 20 is provided with a groove 40 , and the outer wall of the nozzle at the top of the pipe body 10 is provided with at least two convex rings 30 matched with the grooves 40 .

[0047] Specifically, two convex rings 30 are provided, including the first convex ring 31 and the second convex ring 32. The first convex ring 31 cooperates with the groove 40 to play a pre-fixing function. At the same time, when the second convex ring 32 is fitted with the groove 40 , the convex ring one 31 is attached to the inner wall of the tube cover 20 to form a secondary seal, which greatly improves the sealing effect.

[0048] In some embodiments, as figure 2 As shown, the top of the tube cover 20 is provided with a pierceable ...

Embodiment 2

[0054] Different from the first embodiment, in this embodiment, the tube cover 20 is inserted into the tube body 10 .

[0055] Specifically, as Figure 4 As shown, a reagent tube includes a tube body 10 and a tube cover 20; a sealing member is provided in the contact area between the tube cover and the tube body, so that the tube cover seals the tube body, wherein the tube A groove 40 is provided at the mouth of the top of the body 10 , and at least three protruding rings 30 are provided on the outer wall of the pipe cover 20 for matching with the grooves 40 .

[0056] Further, a brim 201 is also provided in the opposite direction parallel to the connecting strip, the width of the brim is smaller than the distance between the connecting strips, and the thickness of the brim is less than 0.4 mm.

[0057] In this embodiment, three protruding rings 30 are provided, including the first protruding ring 31, the second protruding ring 32 and the third protruding ring 33. The first p...

Abstract

The invention discloses a reagent tube. The reagent tube comprises a tube body and a tube cover connected with the tube body, wherein the pipe body comprises a cylinder part and a cone-shaped body part, and the wall thickness delta of the cone-shaped body part is smaller than 0.22 mm; a sealing component is arranged at the joint of the tube cover and the tube body so that the tube cover can seal the tube body. Due to the fact that the groove and the protruding ring which can be mutually embedded are arranged on the tube cover and the tube body, and the protruding ring is attached to the inner wall of the tube cover to form secondary sealing, the sealing effect is greatly improved, and the situation that a solution in the tube body leaks is avoided.

Description

technical field [0001] The present application relates to the technical field of medical devices, and in particular, to a reagent tube. Background technique [0002] The polymerase chain reaction (PCR) is a molecular biology technique used to amplify specific DNA fragments. It can be regarded as a special DNA replication in vitro. The biggest feature of PCR is that it can greatly increase the trace amount of DNA. . Polymerase chain reaction technology is widely used in the field of biology, and usually PCR reactions need to be carried out in reagent tubes (PCR tubes). [0003] Existing PCR tubes generally include a tube body. During storage, a tube cover is inserted into the mouth of the tube body to achieve sealing. However, the tube body of the existing PCR tube is made of a hard material as a whole. The material has poor elastic properties and the sealing effect is not good. In order to achieve a better sealing effect. SUMMARY OF THE INVENTION [0004] The embodime...
