Description

Technical Field

[0001] The present invention relates to the technical field of sampling devices, and in particular to a novel sampling device for sperm detection. Background Art

[0002] Sperm quality can be tested using a sperm analyzer. This electronic instrument uses image processing to analyze male semen, determining data such as semen volume, sperm concentration, and sperm motility, thereby determining sperm quality. In the typical sperm sampling process, consumables such as a measuring cup, dropper, and test strips are essential. The specific process is as follows: Place the semen sample in a measuring cup and wait 15-30 minutes for the semen sample to liquefy. Then, insert the dropper into the measuring cup containing the sample to draw a small amount of the sample. The sample is then dripped onto the sample port of the test strip in the sperm analyzer. The test strip is then placed under a microscope to capture a video of the sample, which is then analyzed to obtain the results. This process requires a large number of consumables, is complex, and has a high probability of sample contamination during transfer. This contaminated sperm sample can affect the final test quality and reduce test reliability. Therefore, existing sperm sampling devices are susceptible to contamination during the sampling process.

[0023] It should also be understood that the terms used in the present specification are only for the purpose of describing particular embodiments and are not intended to limit the present invention. As used in the present specification and the appended claims, the singular forms "a", "an", and "the" are intended to include the plural forms unless the context clearly indicates otherwise.

[0024] It should be further understood that the term "and / or" used in the present description and the appended claims refers to and includes any and all possible combinations of one or more of the associated listed items.

[0025] In this example, see Figure 1 and Figure 4 As shown in the figure, an embodiment of the present invention provides a novel sampling device for sperm testing, comprising a sampling cup 10 and a detection groove 11. The sampling cup comprises a base 101, a cup wall 102, and a cup cover 103. The base 101 and the cup wall 102 are detachably connected. A detachable sampling block 104 is provided on the base 101. A protrusion is formed on the sampling block 104. The detection groove 11 is adapted to fit the sampling block 104.

[0026] Specifically, the sampling cup 10 is composed of a base 101, a cup wall 102 and a cup cover 103. When performing semen sample testing, the sampling block 104 and the testing groove 11 can be combined and placed in the sperm detector. Figure 4 As shown, after the user uses the sampling cup 10 to collect semen, he waits for 15-30 minutes for the semen to liquefy. Figure 4(a) As shown. Then, the sampling cup 10 is gently and slowly turned upside down. At this time, some semen sample will remain on the convex top of the sampling block 104, as shown in FIG. Figure 4 (b) As shown. Remove the base 101 and the sampling block 104 assembly from the inverted sampling cup 10, and splice the assembly with the detection groove 11, as shown. Figure 4 As shown in (c), the base 101 is disassembled from the assembly, and the detection groove 11 is now combined with the sampling block 104, as shown in FIG. Figure 4 As shown in (d), after being assembled with the upper lens and the lower lens, a detection sampling piece is formed. Figure 4 As shown in (e), the obtained test sample can be placed in a vertical light source and a microscopic imaging module for testing to obtain corresponding test results.

[0027] In a more specific embodiment, the cross-section of the protrusion is trapezoidal. The sampling block 104 is rectangular, circular, or elliptical. Specifically, the protrusion is an elongated protrusion. The volume of the sampling cup corresponding to the liquid level being flush with the top of the protrusion is less than 5 ml.

[0028] To ensure that semen sample remains on the top of the protrusion of sampling block 104 after sampling cup 10 is inverted, the cross-section of the protrusion in sampling block 104 can be designed to be trapezoidal. When sampling cup 10 is inverted, semen can slide down the sides of the trapezoidal protrusion to the top of the protrusion, resulting in a portion of the semen sample remaining on the top of the protrusion of sampling block 104. To increase the amount of semen sample remaining on the top of the protrusion, thereby facilitating subsequent testing, the protrusion can be designed to be elongated, and the outer shape of sampling block 104 can be configured to be rectangular, circular, or elliptical, so that sampling block 104 is compatible with the elongated protrusion. In this embodiment, the outer shape of sampling block 104 is rectangular, and the elongated protrusion is provided on sampling block 104. The volume V corresponding to the liquid level when the sampling cup is flush with the top of the protrusion can be set to be less than 5 ml. When the sampling cup 10 is placed upright, the volume V corresponding to the liquid level when the sampling cup 10 is flush with the top of the protrusion is less than 5 ml. Normal semen is usually 2-7 ml. Therefore, in order to ensure that there will be residual semen sample on the protrusion, the volume corresponding to the liquid level when the top of the protrusion is flush with the top of the protrusion in the sampling cup 10 is less than 5 ml. This can ensure that when a certain amount of semen is placed in the sampling cup 10, the liquid level can submerge the protrusion, and can also ensure that the residual semen sample can be obtained in cases where there is less or more semen; in a more specific embodiment, the volume V corresponding to the liquid level when the sampling cup is flush with the top of the protrusion can be set to be less than 3.5 ml, so as to ensure that when a small amount of semen is placed in the sampling cup 10, the liquid level can submerge the protrusion; in the optimal embodiment, the volume V corresponding to the liquid level when the sampling cup is flush with the top of the protrusion can be set to be less than 2 ml, so as to ensure that when any amount of semen is placed in the sampling cup 10, the liquid level can submerge the protrusion. In addition, the shape of the top of the protrusion can be a flat surface or a round head. As long as the semen can remain on the top of the protrusion, the top of the protrusion can also be set to any other shape.

[0029] In a more specific embodiment, the opening size of the upper end of the cup wall 102 is larger than the opening size of the lower end. The depth of the detection groove 11 is greater than the height of the protrusion of the sampling block 104.

[0030] To facilitate the collection of semen, the opening size at the upper end of the cup wall 102 can be set to be larger than the opening size at the lower end. The cross-section of the cup wall can be circular, elliptical, or rectangular. Regardless of the shape of the cross-section of the cup wall, the opening size at the upper end can be kept larger than the opening size at the lower end. When the sampling block 104 is upright, the base 101 attachment can collect semen to a certain height, thereby facilitating the semen sample to remain at the top of the protrusion when the sampling block 104 is inverted. A groove matching the protrusion is provided in the detection groove 11. The depth of the groove in the detection groove 11 can be set to be greater than the height of the protrusion in the sampling block 104. When the sampling block 104 with the attached semen sample is combined with the detection groove 11, the attached semen sample can be accommodated in the gap between the protrusion and the groove in the detection groove 11, facilitating subsequent detection operations.

[0031] In a more specific embodiment, the base 101 is connected to the cup wall 102 by snapping. Alternatively, the base 101 is connected to the cup wall 102 by screwing. The cup wall 102 is provided with a scale 105.

[0032] The base 101 and the cup wall 102 can be connected by a snap-fit ​​method, such as providing a snap-fit ​​and a bayonet connection, or by a screw-fit method, such as providing an internal thread on the base and an external thread on the cup wall for a rotational connection. To enhance the tightness of the connection between the base 101 and the cup wall 102, a sealing ring can be provided between the base 101 and the cup wall 102. A scale 105 can be provided on the cup wall 102, and when semen is placed in the sampling cup 10, the scale can be used to read the amount of semen inside.

[0033] Conventional sperm sampling procedures require numerous consumables and complex procedures, leading to a high probability of sample contamination. The present invention is a simple, easy-to-use sampling device for sperm testing. By improving upon the existing sampler structure, it simplifies the sperm sampling process, reduces consumables, and minimizes the likelihood of sample contamination, thereby enhancing sampling reliability and improving detection efficiency.

[0034] In the common sperm testing sampling process, measuring cups, droppers, and test strips are essential consumables. However, the novel sampling device of the present invention is simplified into two parts: a sampling cup 10 and a test groove 11. Furthermore, most consumables on the market are vacuum-packed, and the volume of the vacuum packaging itself is 5-10 times the size of the consumables inside. Therefore, the present invention reduces the number of sampling consumables while also saving packaging costs and space.

[0035] The novel sampling device employed in this invention features a structural improvement that simplifies the sperm sampling process. The simplified process is as follows: A semen sample is collected using a sampling cup 10. After the semen sample liquefies, the cup 10 is slowly inverted. A sampling block 104, which contains a small amount of semen sample, is removed and joined to the detection groove 11 to form a detection sampling unit, which can then be placed under a microscope for observation and analysis.

[0036] Furthermore, during the sperm sampling process using the novel sampling device of the present invention, the sperm sample comes into contact with fewer consumables, and the base 101 at the upper end of the sampling block 104 is removed prior to microscopic analysis. Therefore, the present invention reduces the possibility of sample contamination and provides clearer and more accurate microscopic imaging results.

[0037] An embodiment of the present invention provides a novel sampling device for sperm testing. The novel sampling device includes a sampling cup and a testing groove. The sampling cup includes a base, a cup wall, and a cup cover. The base and the cup wall are detachably connected. A detachable sampling block is provided on the base. A protrusion is formed on the sampling block, and the testing groove is adapted to fit the sampling block. The novel sampling device described above places the collected semen in the sampling cup. After a period of time, the semen liquefies and the sampling cup is inverted. The sampling block, which is dipped in a small amount of semen sample, is removed from the sampling cup and placed in the testing groove for testing. This reduces the number of operating steps in the semen sampling process, avoids contamination of the sperm sample during the sampling process, and can significantly improve the reliability of sperm testing.

[0038] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and such modifications or substitutions are intended to be within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be subject to the scope of protection of the claims.
