Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a PCR tube-assisted cap-opening device. Background Technology

[0002] PCR tubes 10 (e.g., PCR eight-tube bundle) are side-by-side tube structures composed of several tube bodies 101 arranged at intervals and several tube caps 102 arranged at intervals; the number of tube bodies 101 is the same as the number of tube caps 102. Figure 1 As shown, two adjacent tubes 101 are connected by tube connecting straps 103, and all tubes 101 and all tube connecting straps 103 are integral structures; two adjacent tube caps 102 are connected by tube cap connecting straps 104, and all tube caps 102 and all tube cap connecting straps 104 are integral structures. The tube connecting straps 103 and the tube cap connecting straps 104 above them are arranged alternately, with a connecting strap gap 105 between them. When performing a PCR reaction using the PCR tubes 10, medical personnel need to first open the tube caps 102 of the PCR tubes 10, and then add the sample into each tube 101.

[0003] The Chinese utility model patent with patent number ZL 202422296734.0 and patent name "A PCR tube cap opener" specifically discloses the following technical solution: A PCR tube cap opener, including a plate assembly and a support assembly. The plate assembly includes a lower plate and an upper plate rotatably connected to the lower plate. The support assembly includes a grip rod fixedly connected to the rear end of the lower plate and a rotating rod fixedly connected to the upper plate. The lower plate is provided with multiple lower rods, and the upper plate is provided with multiple upper rods. The front ends of the lower rods and the upper rods are rotatably hinged.

[0004] When using the PCR tube opener described above to open PCR tubes, first place the PCR tubes into the appropriate tube rack box to position the tubes. Then, insert the tips of the multiple lower rods into the connecting gaps between the eight PCR tubes. During the opening action, the operator holds the handle with one hand and presses the lower plate so that the lower rod on the lower plate is pressed tightly against the connection of the PCR tubes. The other hand holds the rotating rod and rotates it upward so that the upper rod pushes open the tube cap, thus completing the opening operation.

[0005] However, the aforementioned PCR tube opener still has the following drawbacks, specifically:

[0006] Defect 1: Because opening the cover requires pressing down through the lower insert plate, this downward pressing action can easily cause the tube rack box to tip over, resulting in poor stability during use.

[0007] Defect 2: When opening the lid, the operator needs to operate the lever of the lower insert plate with one hand and the rotating lever of the upper insert plate with the other hand. That is, both hands are required to open the lid, which makes it inconvenient to use. Utility Model Content

[0008] The purpose of this invention is to provide a PCR tube opening aid device to address the shortcomings of existing technologies. This PCR tube opening aid device has a novel structural design, is easy to use, and has good stability.

[0009] To achieve the above objectives, this utility model is implemented through the following technical solution.

[0010] A PCR tube opening aid includes a tube rack body, and the upper end of the tube rack body has a plurality of tube placement holes arranged from left to right at intervals and opening upwards respectively.

[0011] The upper end of the pipe rack body is provided with an upwardly protruding fixed vertical plate on the rear end side of the pipe placement hole;

[0012] A rotating plate is rotatably mounted on the front end of the pipe placement hole of the pipe rack body. The lower end of the rotating plate is hinged to the pipe rack body via a pivot. Several wedge-shaped protrusions are arranged from left to right at intervals and are wedge-shaped respectively. Each wedge-shaped protrusion protrudes from the rear surface of the rotating plate and is perpendicular to the rotating plate. The wedge-shaped protrusions and the rotating plate are an integral structure.

[0013] When using the PCR tube-assisted cap-opening device to open the cap, each tube of the PCR tube is inserted into the corresponding tube placement hole of the tube rack body, and the rotating plate is flipped so that each wedge-shaped protrusion is inserted into the corresponding connection strip gap of the PCR tube.

[0014] The fixed vertical plate is provided with a clearance hole corresponding to each of the wedge-shaped protrusions.

[0015] The fixed vertical plate is provided with a fixed handle at its upper end, and the rotating plate is provided with a rotating handle at its upper end.

[0016] The tube frame body is equipped with an auxiliary stop block on the front end side of the rotating plate. When the rotating plate is flipped forward to the limit position, the front surface of the rotating plate abuts against the auxiliary stop block.

[0017] The main body of the pipe rack and the fixed vertical plate are an integral structure.

[0018] The lower surface of the main body of the pipe rack is equipped with an anti-slip pad.

[0019] Compared with the prior art, the present invention has the following beneficial effects, specifically:

[0020] 1. Since the fixed vertical plate is connected to the main body of the pipe rack and the rotating plate is hinged to the main body of the pipe rack, the main body of the pipe rack will not tip over when the rotating plate is rotated and the fixed vertical plate and the rotating plate are brought together and closed. Compared with the prior art, the present invention has better stability in use.

[0021] 2. The operator can close the fixed vertical plate and the rotating plate with one hand, which makes the present invention more convenient to use than the prior art.

[0022] 3. Therefore, the PCR tube-assisted cap-opening device of this utility model has the advantages of novel structural design, convenient use and good stability. Attached Figure Description

Detailed Implementation

[0031] The present invention will now be described in conjunction with specific embodiments.

[0032] Example 1, as Figures 2 to 5As shown, a PCR tube-connecting auxiliary capping device includes a tube rack body 1, and the upper end of the tube rack body 1 has a plurality of tube placement holes 11 arranged sequentially from left to right and opening upwards respectively.

[0033] Among them, such as Figures 2 to 5 As shown, a fixed vertical plate 2 protruding upwards is provided at the upper end of the pipe support body 1 at the rear end of the pipe placement hole 11. It should be explained that the fixed vertical plate 2 in this embodiment can be a one-piece structure design or a split structure design; for the fixed vertical plate 2 with a one-piece structure design, the pipe support body 1 and the fixed vertical plate 2 are a single structure; for the fixed vertical plate 2 with a split structure design, the fixed vertical plate 2 can be fastened to the upper end of the pipe support body 1 by screwing.

[0034] Furthermore, such as Figures 2 to 5 As shown, a rotating plate 3 is rotatably mounted on the front end of the pipe body placement hole 11 of the pipe support body 1. The lower end of the rotating plate 3 is hinged to the pipe support body 1 via a pivot 4. Several wedge-shaped protrusions 31 are arranged from left to right at intervals and are wedge-shaped respectively on the rear surface of the rotating plate 3. Each wedge-shaped protrusion 31 protrudes from the rear surface of the rotating plate 3 and is perpendicular to the rotating plate 3. The wedge-shaped protrusions 31 and the rotating plate 3 are an integral structure.

[0035] When using the PCR tube-assisted cap-opening device of this embodiment to open the cap, the operation process includes the following steps, specifically:

[0036] Step a: Insert each tube body 101 of the PCR tube 10 into the corresponding tube body placement hole 11 of the tube rack body 1. The tube rack body 1 positions the tube body 101 of the PCR tube 10 through the tube body placement hole 11.

[0037] Step b: Flip the rotating plate 3 toward the fixed vertical plate 2. At this time, the rotating plate 3 rotates around the pivot 4 as the center of rotation. During this process, each wedge-shaped protrusion 31 of the rotating plate 3 is aligned and inserted into the gap 105 of each connecting strip of the PCR tube 10. As the rotating plate 3 gradually rotates toward the fixed vertical plate 2, each wedge-shaped protrusion 31 pushes upward against the corresponding tube cap connecting strip 104, thereby causing the tube cap 102 of the PCR tube 10 to gradually move upward and retract from the tube body 101 to complete the opening operation.

[0038] It should be emphasized that during the opening operation using the PCR tube-assisted capping device of this embodiment, when the wedge-shaped protrusion 31 of the rotating plate 3 is inserted into the gap 105 of the connecting strip of the PCR tube 10, the wedge-shaped protrusion 31 is positioned above the tube body connecting strip 103. This effectively prevents the tube body 101 of the PCR tube 10 from exiting the tube body placement hole 11 of the tube rack body 1. Furthermore, since the fixed vertical plate 2 is connected to the tube rack body 1 and the rotating plate 3 is hinged to the tube rack body 1, the tube rack body 1 will not tip over when the rotating plate 3 is rotated and the fixed vertical plate 2 and the rotating plate 3 are brought together and closed. Compared to the prior art, this embodiment has better stability in use.

[0039] It should be further emphasized that the operator can close the fixed vertical plate 2 and the rotating plate 3 with one hand, which is more convenient to use than the prior art. In addition, when the rotating plate 3 pushes the tube cap connecting strap 104 of the PCR tube 10 upward through the wedge-shaped protrusion 31, the force application position of the rotating plate 3 is at the upper end. At this time, the entire rotating plate 3 is like a lever structure, which can achieve the effect of saving effort.

[0040] In summary, the PCR tube-assisted capping device of this embodiment has the advantages of novel structural design, convenient use, and good stability.

[0041] Example 2, as Figures 2 to 5 As shown, the difference between this embodiment 2 and embodiment 1 is that: the fixed vertical plate 2 is provided with a clearance through hole 21 for each wedge-shaped protrusion 31.

[0042] Regarding the clearance through hole 21 in this embodiment 2, when the rotating plate 3 is flipped upward to the limit position, each wedge-shaped protrusion 31 is inserted into the corresponding clearance through hole 21 to avoid interference between the wedge-shaped protrusion 31 and the fixed vertical plate 2.

[0043] Example 3, as Figures 2 to 5 As shown, the difference between this embodiment 3 and embodiment 1 is that: the upper end of the fixed vertical plate 2 is provided with a fixed handle 22, and the upper end of the rotating plate 3 is provided with a rotating handle 32.

[0044] When the operator flips the rotating plate 3 and closes it with the fixed vertical plate 2, the fixed handle 22 and the rotating handle 32 of this embodiment can be easily operated by the operator with one hand to hold the fixed vertical plate 2 and the rotating plate 3.

[0045] Example 4, as Figure 4 As shown, the difference between this embodiment four and embodiment one is that: the tube frame body 1 is equipped with an auxiliary stop block 5 on the front end side of the rotating plate 3. When the rotating plate 3 is flipped forward to the limit position, the front surface of the rotating plate 3 abuts against the auxiliary stop block 5.

[0046] Example 5, as Figures 2 to 5 As shown, the difference between this fifth embodiment and the first embodiment is that the lower surface of the tube rack body 1 is equipped with an anti-slip pad 6.

[0047] The anti-slip pad 6 in this embodiment 5 can effectively improve the anti-slip effect of the pipe rack body 1, thereby improving the stability of the pipe rack body 1.

[0048] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
