Description

Technical Field

[0001] The utility model belongs to the technical field of orifice plate manufacturing, and particularly relates to an orifice plate. Background Art

[0002] Orifice plates are often used in research and development, especially in the life sciences and pharmaceutical industries. Using an orifice plate for biochemical experiment detection is a common method, which is often used in various experiments such as disease protein quantification, enzyme activity determination, ELISA, cell detection, molecular interaction, and kinetics. It has the advantages of less consumption and batch operation.

[0003] Common orifice plates are mostly in the specifications of 12-well, 24-well, 48-well, 96-well and 128-well whole plates. For details, reference can be made to the structure of the patent CN201220130089.X, "Microplate". In most existing solutions including this patent, since the specifications and the number of holes of the orifice plate are fixed, that is, only an orifice plate with 12 holes or 24 holes or 48 holes or 96 holes can be used. Once the number of detections is greater than the rated number of any orifice plate and less than the number of this orifice plate or other orifice plates, for example, when the number of test tubes to be detected is 28, only a combination of 12-well plates and 24-well plates or a combination of 3 12-well plates can be used. However, no matter which combination method is used, some micro-holes will be left over, resulting in a blank phenomenon and a large amount of waste.

[0004] To solve the above problems, designing a Lego-style spliced orifice plate is an important technical problem that those skilled in the art need to solve at present. Content of the Utility Model

[0034] As Figure 1 and Figure 3 shown, or as Figures 5 to 6 , or as Figures 7 to 8 , or as Figures 9 to 10 shown, the present utility model discloses a Lego - type splicing orifice plate, including at least one test - tube unit. Each of the test - tube units includes a separately - provided test - tube base 1 and a test - tube cap 2. The test - tube base 1 and the test - tube cap 2 can be made of plastic or silica gel; of course, the test - tube base 1 and the test - tube cap 2 can also be made of other known materials disclosed in the existing technologies, which will not be elaborated here. In the first to the fourth embodiments, it is preferably that the height of the test - tube cap 2 is not less than the height of the test - tube base 1; of course, it does not exclude the case where the height of the test - tube cap is designed to be less than the height of the test - tube base 1 in other embodiments, and it can be specifically adjusted according to the usage occasion, which will not be limited here.

[0035] At least one receiving groove 10 is provided on both the test - tube base 1 and the test - tube cap 2, and they correspond to each other one by one. The two are stacked up and down to form a receiving cavity for placing the test tube. Specifically, the number of the receiving grooves 10 provided on the test - tube base 1 and / or the test - tube cap 2 can be composed of an integral structure in units of two, three or four. The number of the receiving grooves on the same test - tube base 1 can be adjusted according to the usage requirements, which will not be limited here.

[0036] Combined with Figure 2 and Figure 4 shown, the bottom of the receiving cavity is higher than the bottom surface of the test - tube base 1, and the top of the receiving cavity is lower than the top surface of the test - tube cap 2; and connecting bridges 101 are provided on the inner surfaces of the four side walls of the test - tube base 1 or the test - tube cap 2; and the ends of the connecting bridges 101 are flush with the end surfaces of the test - tube base 1 or the test - tube cap 2. Designing the height of the receiving cavity to be less than the heights of the test - tube base 1 and the test - tube cap 2 and providing connecting bridges therebetween can facilitate the stacking of different test - tube units, and the connecting bridges play a role in limiting and stabilizing.

[0037] Through holes 102 are provided at the ends of the receiving grooves 10 located on the test - tube base 1 and / or the test - tube cap 2.

[0038] As Figure 1 or Figure 5 or Figure 7 or Figure 9As shown, preferably, at least the inner wall of the receiving groove 10 of the test tube holder 1 is integrally provided along the direction perpendicular to the axis of the receiving cavity; the receiving strip 103 is made of silica gel. The inner diameter of the receiving strip 103 is smaller than the inner diameter of the receiving groove 10. The inner diameter of the receiving groove 10 can be adjustably reduced by the receiving strip 103 to meet the stability of placing a test tube with a smaller diameter in the receiving groove 10; at the same time, when the diameter of the test tube is equal to the diameter of the receiving groove 10, the receiving strip 103 can increase the friction during the placement and storage of the test tube, ensuring the stability of the test tube after placement.

[0039] As Figures 1 to 10 As shown, clamping grooves 121 and bumps 122 are arranged at intervals on the four side walls of the test tube unit. To ensure the clamping stability and reliability, in the present utility model, preferably, the clamping groove 121 is a dovetail groove; the end width of the bump 122 is smaller than the main body width of the connecting part that mates with it, and matches the clamping groove 121 on the adjacent test tube unit.

[0040] Furthermore, the width of at least one end of the bump 122 is smaller than the width of its main body part, playing a role in splicing guidance, facilitating the quick and accurate docking of different test tube units or the test tube holder 1 and the test tube cap 2, and realizing the storage of the required number of test tubes to be tested.

[0041] The arrangement modes of the clamping grooves 121 and the bumps 122 on the two relatively arranged side walls are different, that is, a clamping groove 121 and a bump 122 are arranged on the same axis and are respectively located on two relatively arranged side walls; for example, if one side wall of the test tube unit is arranged in a cycle of the clamping groove 121 and the bump 122, then the side wall opposite to this side wall is arranged in a cycle of the bump 122 and the clamping groove 121. By providing the clamping structure of the clamping groove 121 and the bump 122 on the side wall of the test tube unit, the combined assembly between different test tube units can be realized, so that the number of receiving cavities is the same as the number of test tubes to be detected.

[0042] As Figures 1 to 4 As shown is the first embodiment of the present application. In the first embodiment, the receiving grooves 10 provided on the test tube holder 1 and / or the test tube cap 2 form an integral structure in units of four, that is, there are 4 receiving grooves 10 on the test tube unit in this embodiment. This embodiment is applicable to application places where the number of test tubes to be tested is an integer multiple of 4. Of course, it can also be spliced with one or two or three test tube holders 1 and test tube caps 2 through the clamping grooves 121 and the bumps 122 provided on the test tube holder 1 and the test tube cap 2 to form a test tube unit with 4n + 1 or 4n + 2 or 4n + 3 receiving grooves 10; where n is a natural number.

[0043] As Figures 5 to 6The following shows the second embodiment of the present application. Different from the first embodiment, in the second embodiment, the receiving grooves provided on the test tube base 1 and / or the test tube lid 2 form an integrated structure in units of 24, that is, there are 24 receiving grooves 10 on the test tube unit in this embodiment. Compared with the first embodiment, the second embodiment can reduce the splicing times, thereby improving the use efficiency. Of course, the test tube unit in this embodiment can be spliced with a test tube unit having one or two or three or four receiving grooves 10 to form a test tube unit having 4n + 1 or 4n + 2 or 4n + 3 or 4n + 4 receiving grooves 10; where n is a natural number.

[0044] As Figures 7 to 8 The following shows the third embodiment of the present application. Different from the above two embodiments, in the third embodiment, the receiving grooves provided on the test tube base and / or the test tube lid form an integrated structure in units of 48, that is, there are 48 receiving grooves 10 on the test tube unit in this embodiment. When the number of test tubes to be detected is greater than 48, the test tube unit in this embodiment can be spliced with a test tube unit in any one of the above two embodiments, or a test tube unit having one or two or three or four receiving grooves 10 to form a test tube unit having 48n + 1 or 48n + 2 or 48n + 3 or 48n + 4 or 72n or 72n + 1 or 72n + 2 or 72n + 3 or 72n + 4 receiving grooves 10; where n is a natural number.

[0045] As Figures 9 to 10 The following shows the fourth embodiment of the present application. In the fourth embodiment, the receiving grooves provided on the test tube base and / or the test tube lid form an integrated structure in units of 96, that is, there are 96 receiving grooves 10 on the test tube unit in this embodiment. When the number of test tubes to be detected is greater than 96, the test tube unit in this embodiment can be spliced with a test tube unit in any one or two or three of the above embodiments, or a test tube unit having one or two or three or four receiving grooves 10 to form a test tube unit having 96n + 1 or 96n + 2 or 96n + 3 or 96n + 4 and other numbers of receiving grooves 10; where n is a natural number.

[0046] In the first to fourth embodiments described above, 4 or 24 or 48 or 96 of the receiving grooves 10 are provided on the same test tube holder 1, which can be stacked up and down with the test tube cap 2 integrally provided with 4 or 24 or 48 or 96 of the receiving grooves 10; it can also be stacked up and down with the test tube cap 2 separately composed of 1 or 2 or 4 of the receiving grooves 10. When the number of the test tube caps 2 equal to the number of the receiving grooves 10 on the test tube holder 1 is used in the first case, the time for storing and sealing all the test tubes to be tested can be reduced; when the number of the test tube caps 2 less than the number of the receiving grooves 10 on the test tube holder 1 is used in the second case, the tested and untested test tubes can be quickly distinguished during the detection process, reducing the possibility of errors in the detection results.

[0047] As Figure 11 shown, a label plate 123 is clamped on the outer wall of the test tube unit. The card slots 121 and the bumps 122 are formed on the label plate 123 and are clamped with the card slots 121 and the bumps 122 on the test tube unit. The label plate 123 can be used to mark the number, time, detection content, etc. of the test tubes to be tested located on one test tube unit or on a total test tube unit, facilitating quick identification by the testers or the test system.

[0048] Row marks and column marks corresponding to the receiving grooves 10 are provided on the parting surfaces of the test tube holder 1 and / or the test tube cap 2. In the present utility model, it is preferably that the row marks are sequentially marked with English letters A, B, C, etc.; the column marks are sequentially marked with natural numbers such as Arabic numerals 1, 2, 3, etc.; specifically, it can be adjusted according to the use requirements. By providing row marks and column marks on the parting surfaces of the test tube holder 1 and / or the test tube cap 2, the coordinates of each of the receiving grooves 10 and the test tubes placed therein are represented.
