Detailed Implementation

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to specific embodiments.

[0027] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] In the description of this utility model, "several" means one or more, "multiple" means two or more, "greater than," "less than," "exceeding," etc. are understood to exclude the stated number, while "above," "below," "within," etc. are understood to include the stated number. If terms such as "first," "second," etc., are used only to distinguish technical features and should not be construed as indicating or implying relative importance, or implicitly specifying the number of indicated technical features, or implicitly specifying the order of the indicated technical features.

[0029] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0030] like Figures 1-4 As shown, the sample cup of this utility model includes a cup body 1 and a cup lid 2.

[0031] The cup body 1 has a cavity inside that holds biological fluid samples (such as semen).

[0032] The lid 2 is attached to the opening at the top of the cup body 1. The lid 2 and the cup body 1 can be connected by means of screwing or interference fit. Several anti-slip grooves 24 can also be provided on the surface of the lid 2 to facilitate the removal of the lid 2 from the cup body 1.

[0033] To simplify the sample transfer process from the sample cup, this invention includes a sealing plate 22 on the cup lid 2, consisting of multiple elastic flaps 222. These elastic flaps 222 are arranged close together or partially overlapped to minimize gaps and prevent dust and other debris from entering the cup body 1 and contaminating the sample. A pipetting device (e.g., a pipette) can pass through the sealing plate 22 into the cup body 1 to pick up and place biological fluid samples. Since the biological fluid samples in the cup body 1 can be picked up and placed without opening the cup lid 2, the sample transfer process from the sample cup is simplified.

[0034] The sealing piece 22 and the cup lid 2 can be integrally molded, for example, made of polypropylene (PP) or silicone, preferably a transparent material for easy observation. Correspondingly, the cup body 1 can also be made of polypropylene (PP) or silicone, preferably a transparent material for easy observation.

[0035] The sealing piece 22 can also be detachably connected to the cup lid 2, for example, by snap-fit, fastening, or interference fit. As an optional embodiment, the cup lid 2 has a mounting through hole. Figure 8 and Figure 9 As shown, the sealing piece 22 includes an annular portion 221 and elastic flaps 222. The outer periphery of the annular portion 221 has a groove 2211 for engaging with the mounting through hole; a plurality of elastic flaps 222 are circumferentially distributed on the inner periphery of the annular portion 221 to form the sealing piece 22. The sealing piece 22 and the cup lid 2 are separate components, allowing them to be made of different materials, such as polypropylene (PP) for the cup lid 2 and silicone for the sealing piece 22, to meet specific requirements.

[0036] As an optional implementation method, such as Figure 4 , Figure 6 and Figure 7 As shown, the middle part of the cup lid 2 can be recessed downward to form an extension 21; the sealing piece 22 is disposed at the bottom of the extension 21. The extension 21 makes it easier for the pipetting device to be aligned when passing through the sealing piece 22; and if the pipetting device accidentally carries out some sample during the liquid collection process, this sample will also drip into the extension 21, thereby preventing it from dripping outside the sample cup; and if the sample cup is accidentally overturned, the sample in the cup body 1 will not easily flow out from the sealing piece 22.

[0037] Optionally, the sealing piece 22 is integrally formed with the extension 21.

[0038] The sealing piece 22 can also be detachably connected to the extension 21, for example, by snap-fit, fastening, or interference fit. As an optional implementation, such as... Figure 4 As shown, the bottom of the extension 21 has a through hole 23. (As indicated...) Figure 8 and Figure 9 As shown, the sealing piece 22 includes an annular portion 221 and elastic flaps 222. The outer periphery of the annular portion 221 has a groove 2211 for engaging with the through hole 23; a plurality of elastic flaps 222 are distributed circumferentially on the inner periphery of the annular portion 221 to form the sealing piece 22.

[0039] As an optional implementation method, such as Figure 5 As shown, the cup body 1 may include a cup body 11 and a cup base 12 located at the bottom of the cup body 11. The cup body 11 has an internal cavity for holding biological fluid samples (e.g., semen). The cup base 12 is used to increase the stability of the entire sample cup when placed.

[0040] The cup body 11 gradually decreases in size from top to bottom, and the cup base 12 is larger than the lower part of the cup body 11, making the entire sample cup resemble a stemmed glass. Compared to existing cylindrical sample cups, the stemmed glass-shaped sample cup described in this invention is easier to handle. Here, "size" mainly refers to the diameter at the cross-section.

[0041] The inner wall of the cup body 1 is a smooth surface, so that the sample can automatically flow downward under the action of gravity and be concentrated at the bottom of the cup body 11. At the same time, the gradual decrease in size from top to bottom of the cup body 11 also helps to concentrate the sample at the bottom of the cup body 11 when the sample is small, so as to facilitate liquid collection.

[0042] Optional, such as Figure 5 As shown, the cup body 11 is divided into a large-size section 111, an arc-shaped transition section 112, and a small-size section 113 from top to bottom. The cup seat 12 is located at the bottom of the small-size section 113; the size of the cup seat 12 is larger than the size of the small-size section 113. The small-size section 113 has a liquid collection chamber 114; the liquid collection chamber 114 is located below the sealing plate 22. When the amount of sample in the cup body 11 is small, the sample will flow down along the smooth surface of the inner wall of the arc-shaped transition section 112 into the liquid collection chamber 114. Since the size of the liquid collection chamber 114 is small, the sample is concentrated in the liquid collection chamber 114, which facilitates the liquid collection device to collect the liquid. Preferably, the bottom of the liquid collection chamber 114 can be designed with a slightly concave shape at the center, such as a cone or arc, to facilitate the concentration of the sample.

[0043] like Figure 5 As shown, a groove 121 can also be provided at the bottom of the cup holder 12, so that when the sample cup is placed on a smooth surface, the air in the groove 121 is squeezed to adhere the cup holder 12 to the smooth surface, preventing the sample cup from accidentally tipping over. In this case, the cup body 1 is preferably made of a relatively soft material such as silicone to facilitate squeezing.

[0044] For surfaces that are not very smooth, a counterweight can be installed at the groove 121 to lower the center of gravity of the entire sample cup, making it more stable when placed and less likely to tip over.

[0045] The groove 121 can be any shape, such as circular or polygonal. The shape of the counterweight is preferably the same as that of the groove 121. The counterweight can be installed in the groove 121 by adhesive bonding.

[0046] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0047] The above preferred embodiments should not be considered as limitations on this utility model, and the scope of protection of this utility model should be determined by the scope defined in the claims. For those skilled in the art, several improvements and modifications can be made without departing from the spirit and scope of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
