Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a detachable quantitative orifice plate. Background Technology

[0002] PCR plates are devices used for polymerase chain reaction (PCR) experiments. In the PCR process, specific DNA fragments need to be amplified to a certain quantity. Each well has its own unique identity. By distributing different mixtures into each well, each well can undergo only one PCR cycle, thereby achieving high-throughput, rapid and accurate DNA amplification. Therefore, it can be ensured that only one specific sample is used in each reaction.

[0003] Existing PCR plates typically use a 96-well or 384-well design, generally designed for single use. Once the experiment is completed, the plate is not reused to avoid contamination, thus ensuring the accuracy and reliability of the experiment. However, in actual experiments, there may be situations where not all wells are used, resulting in the waste of unused wells. Furthermore, when adding samples to the wells, the wells are densely packed, and if the operator makes a mistake, samples may be added to wells that have already been used, leading to cross-contamination of the samples. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a disassembled quantitative orifice plate that can be used as needed to avoid cross-contamination.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A detachable quantitative well plate includes several plate bodies. Several sample dispensing tubes are fixedly connected to the top of each plate body, and the sample dispensing tubes penetrate the top of the plate body. A protective mechanism is installed on each plate body to guide the dispensing of samples to the sample dispensing tubes. Opposite mounting grooves and receiving grooves are formed around the top of each plate body. A connecting mechanism is installed inside the mounting groove, and a receiving mechanism is installed inside the receiving groove. Several plate bodies are connected to each other through the connecting mechanism and the receiving mechanism.

[0007] The connecting mechanism includes a second protrusion and two racks connected to each other. The second protrusion is stepped on the side near the outside. The racks are arranged on both sides of the second protrusion on the side near the outside and are parallel to the plate. The second protrusion is slidably connected to the mounting groove.

[0008] The receiving mechanism includes an "L"-shaped first protrusion, with gears fixedly connected to both sides of the first protrusion. The gears are rotatably connected to the inner wall of the receiving groove. A spring block is fixedly connected to the bottom inner wall of the receiving groove, and the top of the spring block abuts against the first protrusion.

[0009] The protective mechanism includes a protective shell that is slidably connected to a plurality of the plates. The top of the protective shell is provided with a through groove, and the two sides of the through groove are provided with L-shaped sliding grooves facing each other. The through groove and the sliding groove are connected to each other.

[0010] The chute is slidably connected to the same U-shaped plate, the U-shaped plate has a sample loading groove in the middle, one side of the U-shaped plate passes through the chute and is fixedly connected to a handle, and the other side of the U-shaped plate away from the handle passes through the chute and is fixedly connected to a connecting plate.

[0011] A spring is provided on the top of the connecting plate, one end of the spring is fixedly connected to the U-shaped plate, and a trapezoidal block is fixedly connected to the other side of the spring; a fixing block is fixedly connected to the top of the protective shell, and a toothed plate that fits and abuts against the trapezoidal block is fixedly connected to the side of the fixing block near the trapezoidal block.

[0012] The top inner wall of the protective shell is fixedly connected to a third protrusion that can abut against the first protrusion to limit the sliding of the protective shell.

[0013] A protective frame is rotatably connected to the top of the protective shell, and the protective frame is used to protect the trapezoidal block from sliding on the toothed plate.

[0014] A rotating plate is rotatably connected to the top of the plate on the side of the receiving groove, and the rotating plate is used to restrict the rotation of the first protrusion.

[0015] A limiting block is fixedly connected inside the receiving groove. The side of the limiting block closest to the first protrusion is arc-shaped. The limiting block is used to restrict the rotation path of the first protrusion.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] This invention, by setting up a receiving mechanism and a connecting mechanism, allows two plates to be installed together. The plates are placed side-by-side, with the receiving groove of one plate facing the mounting groove of the other. A second protrusion inside the mounting groove is pushed from the top towards the receiving groove of the other plate, causing a rack to mesh with a gear inside the receiving groove of the other plate. Continuing to push the second protrusion causes the gear to rotate, rotating the L-shaped first protrusion into the receiving groove, compressing a spring block. Then, rotating the rotating plate restricts the rotation of the first protrusion, allowing the two plates to connect. This design allows the plates to be used as needed. When fewer holes are required, rotating the rotating plate releases the restriction on the first protrusion, allowing the second protrusion to be pulled back, separating the two plates. Unused plates can be used for future experiments, avoiding the waste of unused holes by discarding plates when not all holes are needed. Attached Figure Description

[0026] The present invention provides a detachable quantitative orifice plate in detail below with reference to the accompanying drawings and specific embodiments.

[0027] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, a detachable quantitative well plate includes several plate bodies 1. Several sample tubes 2 are fixedly connected to the top of the plate body 1, and the sample tubes 2 penetrate the top of the plate body 1. A protective mechanism 6 is installed on the plate body 1 to guide the sample addition to the sample tubes 2. The top of the plate body 1 is provided with opposing mounting grooves 3 and receiving grooves 11. A connecting mechanism 5 is installed inside the mounting groove 3, and a receiving mechanism 4 is installed inside the receiving groove 11. Several plate bodies 1 are connected to each other through the connecting mechanism 5 and the receiving mechanism 4.

[0028] The connecting mechanism 5 includes a second protrusion 51 and two racks 52 connected to each other. The side of the second protrusion 51 near the outside is stepped. The racks 52 are arranged on both sides of the side of the second protrusion 51 near the outside and are parallel to the plate 1 at the same height. The second protrusion 51 is slidably connected to the mounting groove 3.

[0029] The receiving mechanism 4 includes an "L"-shaped first protrusion 41, with gears 42 fixedly connected to both sides of the first protrusion 41. The gears 42 are rotatably connected to the inner wall of the receiving groove 11. A spring block 43 is fixedly connected to the bottom inner wall of the receiving groove 11, and the top of the spring block 43 abuts against the first protrusion 41.

[0030] A rotating plate 7 is rotatably connected to the top of the plate 1 on the side of the receiving groove 11. The rotating plate 7 is used to restrict the rotation of the first protrusion 41. A limiting block 8 is fixedly connected inside the receiving groove 11. The side of the limiting block 8 near the first protrusion 41 is arc-shaped. The limiting block 8 is used to restrict the rotation path of the first protrusion 41.

[0031] By setting up the receiving mechanism 4 and the connecting mechanism 5, when two plates 1 need to be installed together, the two plates 1 are placed together, so that the receiving groove 11 of one plate 1 is opposite to the mounting groove 3 of the other plate 1. The second protrusion 51 inside the mounting groove 3 is pushed from the top toward the receiving groove 11 of the other plate 1, so that the rack 52 meshes with the gear 42 inside the receiving groove 11 of the other plate 1. The second protrusion 51 is pushed to make the gear 42 rotate, which drives the L-shaped first protrusion 41 to rotate into the inside of the receiving groove 11, squeezing the spring block 43. Then the rotating plate 7 is rotated to restrict the rotation of the first protrusion 41, so that the two plates 1 can be connected together. The advantage of doing this is that the plates 1 can be used according to the needs of the situation.

[0032] When fewer holes are needed, the rotating plate 7 can be rotated to release the restriction on the first protrusion 41, and the second protrusion 51 can be pulled again to separate the two plates 1. The unused plates 1 can be used for the next experiment, avoiding the waste of unused holes caused by discarding plates 1 when not all holes are needed.

[0033] like Figure 1 , Figure 3 and Figure 4 As shown, the protective mechanism 6 includes a protective shell 601 that is slidably connected to several plates 1. A through groove 602 is provided on the top of the protective shell 601, and "L"-shaped sliding grooves 603 are provided on both sides of the through groove 602. The through groove 602 and the sliding groove 603 are connected.

[0034] The same U-shaped plate 604 is slidably connected inside the slide 603. A sample loading groove 605 is opened in the middle of the U-shaped plate 604. A handle 606 is fixedly connected to one side of the U-shaped plate 604 after passing through the slide 603. A connecting plate 607 is fixedly connected to the other side of the U-shaped plate 604 away from the handle 606 after passing through the slide 603.

[0035] A spring 608 is provided on the top of the connecting plate 607. One end of the spring 608 is fixedly connected to the U-shaped plate 604. A trapezoidal block 609 is fixedly connected to the other side of the spring 608. A fixing block 610 is fixedly connected to the top of the protective shell 601. A toothed plate 611 that is adapted to and abuts against the trapezoidal block 609 is fixedly connected to the side of the fixing block 610 near the trapezoidal block 609.

[0036] The top inner wall of the protective shell 601 is fixedly connected to a third protrusion 10 that can abut against the first protrusion 41 to limit the sliding of the protective shell 601. The top of the protective shell 601 is rotatably connected to a protective frame 9, which is used to protect the sliding of the trapezoidal block 609 on the toothed plate 611.

[0037] By setting up the protective mechanism 6, when adding a sample to the sample tube 2, the protective shell 601 can be slid to align the sample groove 605 on the U-shaped plate 604 with the sample tube 2 that needs to be sampled. The sample tube 2 is then sampled through the sample groove 605. After a sample tube 2 has been sampled, the U-shaped plate 604 is slid by the handle 606 to allow the connecting plate 607 to slide on the protective shell 601, thereby driving the trapezoidal block 609 to slide on the toothed plate 611.

[0038] When sliding, the inclined surface of the trapezoidal block 609 leaves the serrated groove of the toothed plate 611 and no longer contacts it. At this time, the spring 608 is compressed. When the U-shaped plate 604 moves above the next sample tube 2, the spring 608 rebounds at the serrated groove of the toothed plate 611. The trapezoidal block 609 re-engages with the serrated groove of the toothed plate 611 through the inclined surface, so that the U-shaped plate 604 is temporarily fixed. At this time, the new sample tube 2 can be sampled.

[0039] After all the sample tubes 2 in a row have been sampled, the protective shell 601 is slid back down to sample the next row of sample tubes 2 one by one. When the protective shell 601 slides to the last plate 1, the third protrusion 10 abuts against the protruding first protrusion 41, stopping the sliding of the protective shell 601. The advantage of this is that the operator can use the sliding of the U-shaped plate 604 in conjunction with the sample groove 605 to sample the next row of sample tubes 2 one by one, avoiding cross-contamination of the sample due to operator error in adding the sample to a previously operated hole. At the same time, the protective shell 601 also protects the other sample tubes 2, preventing the sample from being accidentally added to other rows of sample tubes 2 during sample addition.

[0040] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
