Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary instruments for experiments, in particular to a 96-well plate error prevention device. Background Art

[0002] As an experimental equipment widely used in the fields of enzyme-linked immunosorbent, cell culture, drug screening, gene sequencing, etc., the 96-well plate has become a powerful assistant for scientific research and clinical testing. However, it faces many inconveniences during use. Especially in the addition of samples, there are always problems of adding the wrong sample or forgetting which well to add to. At present, there are also some patents that use LED lights connected to the pipette. Every time a sample is added, the light lights up to indicate that the addition is completed, which reduces the risk of error in adding samples to a certain extent. However, this requires linkage with the pipette, and the maintenance of the LED light and linkage equipment is also required, which is easy to damage and consumes financial resources and time.

[0003] In the prior art, Chinese patent CN220258069U discloses a 96-well plate sample loading error prevention device linked to a pipette, comprising a base, the upper surface of the base is provided with a positioning groove for embedding the bottom surface of the 96-well plate, the interior of the positioning groove is provided with an LED indicator corresponding to the sample loading holes on the 96-well plate one by one, the LED indicator is electrically connected to a control module inside the base, the control module is also electrically connected to a control wire, the end of the control wire is fixedly connected to an arc-shaped slot sheet for being stuck at the bottom of the plunger button of the micropipette, and the arc-shaped slot sheet is fixedly connected to a push-type touch switch electrically connected to the control wire.

[0004] The existing technical means have the following disadvantages:

[0005] 1. It is linked with the sample adding gun, which brings inconvenience to the operator. Every time a gun of a different model is changed, the sample adding error prevention device must be reconnected, which is time-consuming;

[0006] 2. Using LED lights for counting and observation, the sample adding process takes a long time, resulting in long-term viewing of the LED lights, which increases the risk of visual impairment for the sample adder;

[0007] 3. Regular maintenance of linkage equipment and replacement of LED bulbs increases unnecessary costs.

[0008] In view of these shortcomings, the present application provides a 96-well plate sample loading error prevention device to solve the above-mentioned deficiencies. Utility Model Content

[0009] The utility model sets an anti-mistake frame on the 96-well plate 1, sets an opening 3 matching the micro-well 6 of the 96-well plate 1 on the anti-mistake frame, sets tin foil 5 on the anti-mistake frame, covers a part of the opening area of ​​the opening 3, and destroys the tin foil 5 when adding samples, so as to know whether the micro-well 6 under the opening 3 has been added with samples, thereby avoiding mistakes when adding samples. Based on this, the utility model is completed.

[0010] The utility model provides a 96-well plate error prevention device, comprising a 96-well plate 1 and an error prevention frame body 2 covering the 96-well plate 1, the 96-well plate comprising micropores 6, the error prevention frame body 2 is provided with openings 3 matching the micropores 6, the diameter of the openings 3 is consistent with the micropores 6, and it is convenient to add samples to the micropores 6; a layer of tin foil 5 is provided on the error prevention frame body 2, and holes are opened at the openings 3 to cover part of the area of ​​the openings 3, so that part of the openings 3 are opened and part is covered with the tin foil 5. When adding samples, the sample adding device 4 destroys the part of the opening 3 covered with the tin foil, so that it can be clearly observed whether the micropores 6 under the openings 3 have been added with samples, so as to avoid mistakes when adding samples.

[0011] Furthermore, the area of ​​the partial opening at the opening 3 is larger than the area of ​​the portion of the opening 3 covered by the tin foil 5 .

[0012] Furthermore, the covering portion of the tin foil 5 covers to 1 / 4 of the diameter of the opening 3 .

[0013] Furthermore, a vertical mark 8 is provided on one side of the anti-misalignment frame body 2 , and a horizontal mark 9 is provided on an adjacent side. The vertical mark 8 and the horizontal mark 9 are used to identify and locate the opening 3 .

[0014] Furthermore, the tin foil covering the openings 3 is provided with digital identifications, and all the openings 3 are numerically sorted. The clear digital identifications can be intuitively compared with the number of samples to avoid confusion.

[0015] Furthermore, the anti-mistake frame body 2 is made of transparent material for easy observation.

[0016] Furthermore, the anti-mistake frame body 2 is disposable to avoid contamination.

[0017] Compared with the prior art, the 96-well plate error prevention device provided by the utility model has the following technical advantages:

[0018] The utility model provides a 96-well plate error-proofing device. The device improves the stability of the base number by mainly using a mechanical counting technique to add a sample counting rack, and is convenient for operators to use. The use of multiple marks makes the counting intuitive and can be directly checked with the number of samples. Tin foil 5 is attached to a part of each opening 3. When an operator adds a sample to a microwell 6, the sample is generally added to a position close to the bottom of one side of the microwell 6. Therefore, when the gun head is tilted to one side, the tin foil 5 on one side of the opening 3 on the error-proofing rack body 2 is squeezed. The tin foil 5 marked with a number will be incomplete due to being squeezed, and the opening 3 with the incomplete tin foil 5 is regarded as having been filled with the sample in the microwell 6. The device is simple to use and convenient for users to identify.

[0019] Other features and advantages of the present invention will be described in detail in the subsequent specific implementation section. BRIEF DESCRIPTION OF THE DRAWINGS
