[0002] Acquiring sperm is very important in the field of assisted reproduction. How to obtain sperm simply, quickly and without damaging the sperm itself is something that deserves attention. Conventional sperm acquisition methods: After 5 days of abstinence, semen is obtained through masturbation, liquefied at room temperature for 30 minutes, and the liquefied semen is placed in a centrifuge tube. The upstream liquid is gently added to the upper layer. However, during the operation of "gently adding the upstream liquid", the upstream liquid and semen may be mixed together due to operational errors and excessive surface tension of the droplets. When extracting sperm from the upstream liquid, since the upstream liquid and semen are mixed together, it is easy to extract sperm with lower motility below the upstream liquid, affecting the sperm extraction effect, and then affecting the fertilization rate of the egg. Utility Model Content

[0016] The process of adding upstream liquid to semen can easily cause the upstream liquid to mix with the semen. When extracting sperm from the upstream liquid, since the upstream liquid is mixed with the semen, it is easy to extract sperm with lower motility below the upstream liquid, which affects the sperm extraction effect and further affects the fertilization rate of the egg. In view of this, the inventor of the present application provides an upstream tube suitable for sperm extraction. When the upstream liquid is added to the semen, it can prevent the upstream liquid from mixing with the semen. At the same time, when extracting the upstream liquid, it can prevent the sperm with lower motility below the upstream liquid from being extracted.

[0017] like Figure 1-3 As shown, an upstream tube suitable for sperm extraction includes a centrifuge tube 1, which includes a tube cover 11 and a tube body 12. The outer wall of the tube body 12 is provided with scale lines. The tube cover 11 is connected to the opening of the tube body 12. The bottom of the tube body 12 is arc-shaped. A plurality of guide protrusions 13 are provided inside the tube body 12, and the plurality of guide protrusions 13 are evenly arranged on the inner wall of the tube body 12 in a circular shape. One end of the guide protrusion 13 is in the same horizontal plane as one end of the arc at the bottom of the tube body 12, and the other end of the guide protrusion 13 is located at the 1.5 ml scale line on the tube body 12. A guide groove 14 is formed between two adjacent guide protrusions 13.

[0018] Among them, a flow guide component 2 is provided inside the tube body 12, and the flow guide component 2 includes a first flow guide member 21 and a second flow guide member 22. The first flow guide member 21 and the second flow guide member 22 are both truncated cone-shaped, and the first flow guide member 21 and the second flow guide member 22 are both hollow structures. The end of the first flow guide member 21 with a larger diameter is overlapped on the end of the guide protrusion 13 distributed in a circumference, and a plurality of flow guide holes 23 are opened at one end of the first flow guide member 21, and the positions of the flow guide holes 23 and the guide grooves 14 correspond; the other end of the first flow guide member 21 is fixed to the end of the second flow guide member 22 with a larger diameter to form a whole, and a through hole 24 is penetrated through the middle of the first flow guide member 21 and the second flow guide member 22.

[0019] Based on the above embodiment, semen is added into the centrifuge tube 1 through the through holes 24 on the first guide member 21 and the second guide member 22, and the dosage of semen added is 1-1.5 ml, so that the liquid level of the added semen is lower than the bottom of the guide component 2, and upstream liquid is added to the first guide member 21. The upstream liquid flows downward along the inclined surface of the first guide component 21, and the upstream liquid flows to the bottom of the guide component 2 through the guide hole 23, and is guided by the guide groove 14 to avoid the upstream liquid from mixing with the semen due to impact force. The dosage of the upstream liquid added is 2-3 ml, so that the upstream liquid completely submerges the guide component 2.

[0020] In this embodiment, if Figure 1 , Figure 3 As shown, the centrifuge tube is a transparent centrifuge tube made of polypropylene, and the capacity of the centrifuge tube is 10-12 ml; the transparent guide component made of polypropylene is hollow truncated cone as a whole, and the top of the guide component is located below the 2 ml scale line of the tube body.

[0021] Based on the above embodiments, the transparent centrifuge tube 1 and the flow guide assembly 2 made of polypropylene can better observe the conditions of the semen and the upstream liquid therein, and at the same time have good acid resistance, alkali resistance, and corrosion resistance and are not easy to denature.

[0022] In this embodiment, if Figure 3 As shown, the slope of the first air guide 21 is smaller than the slope of the second air guide 22 .

[0023] Based on the above embodiment, the upstream liquid is slowly flowed onto the liquid surface of the semen through the first guide member 21. When the upstream liquid is added, the upstream liquid is avoided from being added into the through hole 24. Since the slope of the second guide member 22 is larger, the through hole 24 can be better avoided when the upstream liquid is added.

[0024] In this embodiment, if Figure 1-2 As shown, an outer wall of one end of the tube body 12 is provided with an outer thread, and an inner wall of the tube cover 11 is provided with an inner thread. The tube body 12 is threadedly connected with the tube cover 11, and a plurality of anti-slip stripes 15 are arranged on the outer wall of the tube cover 11.

[0025] The working principle of the utility model is as follows: unscrew the tube cover 11, add the semen into the lower part of the inner part of the centrifuge tube 1 through the through hole 24 on the second guide member 22, and after adding 1-1.5 ml of semen, add the upstream liquid into the centrifuge tube 1. In the process of adding the upstream liquid, avoid the upstream liquid from dripping directly from the through hole 24 into the lower part of the guide component 2, drop the upstream liquid on the surface of the first guide member 21, and the upstream liquid flows down along the inclined surface of the first guide member 21 to the edge of the first guide member 21, and flows along the guide hole 23 to the guide member 21. The liquid flows to the bottom of the guide component 2 and flows to the liquid surface of the semen through the guide groove 14, thereby avoiding the upstream liquid and the semen from being mixed together due to the liquid impact when the upstream liquid is added to the semen. After 2-3 ml of the upstream liquid is added, the upstream liquid will submerge the guide component 2 as a whole, and the sperm will flow upstream to the top of the guide component through the guide hole 23 and the through hole 24. When extracting the upstream liquid, it is only necessary to avoid the through hole 24 to extract the upstream liquid on the first guide component 21, thereby avoiding the extraction of sperm with lower activity below the guide component 2, thereby improving the fertilization rate of the egg.

[0026] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
