[0048] It should be noted that the drawings provided in the following embodiments only illustrate the basic concept of the present application in a schematic manner.

[0050] The following embodiments of the present application provide a specimen filter plate, which solves the technical problem of how to more easily filter specimens.

[0051] The principle and implementation manner of a specimen filter plate in the following embodiments will be elaborated in detail with reference to the drawings, so that those skilled in the art can understand the specimen filter plate of the embodiments without creative labor.

[0052] As Figures 1 to 6 shown, the present embodiment provides a specimen filter plate, including a filter plate 1 and a centrifugal plate 2. A plurality of first mounting holes 11 are provided on the filter plate 1, and a plurality of filter tubes 12 are arranged on the filter plate 1 through the plurality of first mounting holes 11; a plurality of second mounting holes 21 are provided on the centrifugal plate 2, and a plurality of centrifugal tubes 22 are arranged on the centrifugal plate 2 through the plurality of second mounting holes 21.

[0053] Among them, Figure 3 is a schematic structural diagram of the filter plate 1. Please refer to Figure 3 shown, the plurality of first mounting holes 11 provided on the filter plate 1 are arranged in an array.

[0054] Specifically, a pressing ring 122 is provided on the filter tube 12 , and the filter tube 12 is installed on the filter plate 1 through the pressing ring 122 . Figure 7 and Figure 8 The specific structural design of the pressing ring 111 is shown. When the filter tube 12 is inserted into the first mounting hole 11, since the diameter of the pressing ring 122 is larger than the first mounting hole 11, the filter tube 12 can be fixed to achieve the effect of snap-fit ​​installation. Figure 11 shown.

[0055] Furthermore, a filter membrane is provided under the pressure ring 122. The filter membrane is resistant to high temperatures, and the pore size is sufficient to prevent liquid from leaking easily under micro-motion conditions, thereby achieving liquid filtration under high-speed centrifugation. Figure 6 As shown, the plurality of second mounting holes 21 provided on the centrifugal plate 2 are arranged in an array.

[0056] Figures 9 to 10 The structure of the centrifuge tube 22 is shown. Figure 10 As shown, both sides of the outer wall of the centrifuge tube 22 are provided with an inverted latch 221. Figure 11 The centrifuge tube 22 can be connected with the second mounting hole 21 by the inverted snap-in position 221, that is, the tube body snap-in position is inverted, as shown. Figure 13 As shown, the centrifuge tube 22 is stably mounted on the centrifuge plate 2.

[0057] Please continue reading Figure 1 In the sample filter plate provided in the embodiment of the present application, the filter plate 1 is stacked on the centrifugal plate 2, and the first mounting hole 11 corresponds to the second mounting hole 21. At this time, each of the filter tubes 12 is correspondingly inserted into the centrifugal tube 22. Figure 12 shown.

[0058] Please continue reading Figure 3 and Figure 5 , first fixing members 13 are provided on both sides of the filter plate 1 .

[0059] Please continue reading Figure 6 , second fixing members 23 are provided on both sides of the centrifugal plate 2.

[0060] For details, please refer to Figure 1 and Figure 12As shown, the filter plate 1 and the centrifuge plate 2 are snap-connected through the first fixing member 13 and the second fixing member 23. That is, the forensic sample filter plate provided in the embodiment of the present application includes two layers of plates, namely the upper filter plate 1 and the lower centrifuge plate 2. When the filter plate 1 and the centrifuge plate 2 are stacked, they are snap-connected through the first fixing member 13 on both sides of the filter plate 1 and the second fixing member 23 on both sides of the centrifuge plate 2. At this time, since the first mounting holes 11 and the second mounting holes 21 correspond one by one, the filter tubes 12 inserted into each first mounting hole 11 will correspondingly be inserted downward into the centrifuge tubes 22 in each second mounting hole 21, and the stacking effect is as Figure 1 shown.

[0061] Please continue to refer to Figure 3 shown, at least one through hole 14 is provided on the filter plate 1. Taking the filter plate 1 shown in Figure 3 as an example, a total of 6 through holes are provided thereon, and the 6 through holes are evenly distributed on the filter plate 1. The specific layout can be referred to Figure 3 shown. After the filter plate 1 and the centrifuge plate 2 are stacked, after the forensic sample is heated and filtered, the forensic sample to be retained will enter the centrifuge tube 2, and the substances remaining in the filter tube 12 will be discarded. At this time, in order to perform subsequent centrifugation operations, the filter plate 1 and the centrifuge plate 2 need to be separated. For this purpose, a tool can be used to apply pressure downward on the centrifuge plate 2 through the through hole 14 and apply an upward pushing force with a tool. In this way, the separation of the filter plate 1 and the centrifuge plate 2 can be achieved. The type of the tool can be set according to the specific scenario, and the present application is not limited thereto.

[0062] It should be noted that the structures of the filter plate 1 and the centrifuge plate 2 are the same except that the filter plate 1 is further provided with through holes 14.

[0063] Figures 14 to 15 The structure diagram of the filter tube 12 is shown. Please refer to Figure 14 shown, a filter hole 121 is provided at the bottom of the filter tube 12. After the forensic sample in the filter tube 12 is heated and filtered, it will enter the lower centrifuge tube 22 through the filter hole 121, and the filtered substances will remain in the filter tube 12.

[0064] Please continue to refer to Figure 10 , Z is the angle of inclination inward on both sides of the bottom of the centrifuge tube 22. That is, the bottom of the centrifuge tube 22 is inclined inward on both sides, so that when the forensic sample in the filter tube 12 enters the centrifuge tube 22 after being filtered, it can flow along the bottom inclination angle into the bottom of the tube body, reducing the possibility of adhering to the tube body side wall.

[0065] Further, the length of the centrifuge tube 22 is greater than the length of the filter tube 12, and the upper opening of the centrifuge tube 22 is larger than the bottom diameter of the filter tube 12, so that when the filter plate 1 and the centrifuge plate 2 are stacked, the filter tube 12 located above can be correspondingly inserted into the centrifuge tube 22 below.

[0066] In some embodiments, the specimen filter plate provided by the present application can be used in the experimental cabin. For example, after extracting a biological sample with a cotton swab, it can be placed in the specimen filter plate provided by the embodiments of the present application. After filtration and cell lysis, the liquid on the filter tube is centrifuged to the bottom of the test tube of the lower centrifuge tube. Then, tools such as cotton swabs remaining in the filter tube are discarded. The clamp continues to hold the biological sample in the lower centrifuge tube for subsequent experimental processing, thereby effectively filtering the sample, reducing manual processing steps, and improving the practicability.

[0067] It should be noted that the size parameters in the above-mentioned respective drawings provided by the embodiments of the present application are only illustrative of one embodiment and do not limit the sizes of the respective units in the specimen filter plate provided by the present application.

[0068] A specimen filter plate provided by the present application can be stacked, assembled or separated according to requirements, thereby effectively filtering the specimen and improving the practicability of the specimen filter plate.

[0069] The descriptions of the processes or structures corresponding to the above-mentioned respective drawings each have their own emphases. For parts not detailed in a certain process or structure, reference can be made to the relevant descriptions of other processes or structures.
