Description

Technical Field

[0001] The utility model relates to an anti-pollution PCR tube and belongs to the technical field of biological experimental equipment. Background Art

[0002] The sterilization quality of surgical instruments is closely related to the life safety of patients. Similarly, the sterility quality of laboratory equipment is closely related to the experimental results. If the laboratory equipment is not sterile, it will not only contaminate the experimental reagents and samples, but also may cause laboratory safety accidents and even harm the experimental personnel. Therefore, the awareness of sterile operation occupies a large position in medical experiments.

[0003] The existing PCR test tubes used in laboratories are usually composed of a tube body and a tube cover. Usually, the edge of the tube cover is close to the inner contact part. During the experimental operation, it is difficult for the operator to open the tube cover, and the gloves are easy to touch the inside of the tube cover of the test tube machine, causing contamination to the test tube, so that the desired experimental results can never come out, causing the experimental progress to stagnate and undermining the confidence of the experimenters. Not only that, if the bacteria being tested are seriously lethal, it is also easy to contaminate the operator's limbs and cause infections of varying degrees. Such experimental accidents are common. Specific common PCR test tube structures are as follows: Figure 1 In addition, not only is it easy to touch the inside of a single PCR test tube during operation, but the PCR tube array used in fluorescent quantitative PCR will also cause contamination inside the tube, resulting in a huge deviation in the gradient curve. Therefore, a PCR tube is needed that allows operators to open the tube cover easily without contaminating the tube cover. Utility Model Content

[0004] The utility model aims at solving the problems existing in the prior art and provides an anti-pollution PCR tube.

[0005] The purpose of the utility model is achieved through the following technical scheme: an anti-contamination PCR tube, comprising a tube body, a tube cover and a cover opener, wherein the tube cover is connected to the tube body, and the tube cover and the opening of the tube body form a snap connection; the cover opener is wrapped around the surface of the tube cover, the bottom of the cover opener is tightly fitted with the top wall of the tube cover, and an opening lever is provided on one side of the cover opener, and the tube cover is driven to open by using the opening lever.

[0006] A bending portion is provided between the tube body and the tube cover, and the tube cover rotates around the bending portion to control the opening and closing state of the tube cover.

[0007] The bent portion is provided with a fold.

[0008] The side of the cover opener away from the opening lever is connected to the bent part.

[0009] A detachable nested connection is formed between the cover opener and the tube cover.

[0010] An extension wall is arranged around the outer wall of the tube body.

[0011] The tube cover comprises a cover top wall, a cover side wall and a convex block, wherein the convex block is arranged on one side of the cover top wall, and the cover side wall is located in the opening of the tube body.

[0012] The utility model provides an anti-pollution PCR tube, which can be a single PCR tube or multiple tubes connected together, and is used for opening the tube cover. In order to prevent the leakage of the tube contents, the sealing of the PCR tube is improved by the tube cover, and the tube body and the tube cover are connected by a retractable plastic to prevent falling off. The outer layer cover opener and the tube cover are detachably nested, so the tube cover can be opened at any time without touching the tube cover, and the opening lever can be convenient for the operator to use, thereby improving the operation efficiency.

[0013] The utility model has the following beneficial effects: the utility model increases the sealing and stability of the PCR tube by connecting the tube body and the tube cover, and is not easy to fall off; the tube cover can be opened at any time without contact by connecting the cover opener and the tube cover, and the operator's hand can be prevented from contacting the inside of the tube during operation, thereby avoiding contamination of the PCR tube; the operator can better open the PCR valve by using the opening lever and the cover opener, and also reduce direct contact with the PCR tube; the utility model can not only prevent contamination of the tube cover of the PCR tube during operation, avoid the growth of bacteria or microorganisms, but also better increase the sealing of the tube, and at the same time increase the operating efficiency. It can reduce the contamination rate and achieve aseptic operation. It ensures the aseptic operation required by the experimental process. BRIEF DESCRIPTION OF THE DRAWINGS
