Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to a semen collection optimization cup. Background Art

[0002] Assisted reproductive technology is currently the best treatment for infertile patients, among which semen collection and sperm optimization are important components of assisted reproductive technology. Major reproductive medical centers at home and abroad use wide-mouthed semen collection cups for semen collection, such as "A Semen Collection Cup" with patent number CN202222690953.8 and "A Medical Multifunctional Semen Collection Cup" with patent number CN202221640263.5.

[0003] When optimizing sperm, the swim-up method and density gradient centrifugation method are generally used to optimize the treatment of semen. The swim-up method has the characteristics of simple operation, little damage to sperm, and low cost. The swim-up method is a method that uses the characteristics of high-quality sperm that can swim upward against its own gravity to achieve separation from other sperm and impurities. At present, the embryo laboratory uses ordinary round-bottom test tubes for the swim-up method to treat semen. First, add 2ml of culture medium to the bottom, then draw 0.5-1ml of semen from the semen collection cup and slowly add it to the bottom of the test tube to form two liquid layers, place it at a 45° angle, and place it in a 37°C incubator for 30-60 minutes to collect the supernatant containing high-quality sperm. When using the existing semen collection cup, male patients may not collect semen completely, causing some semen to be omitted outside the semen collection cup, and there is no design to stimulate male patients to ejaculate. Some male patients with difficulty in semen collection cannot ejaculate and obtain semen, and need surgery to collect semen. Furthermore, during the current swim-up method, semen needs to be transferred from a semen collection cup to a test tube, which needs to be carefully checked to avoid confusion when optimizing semen for multiple patients. Furthermore, semen needs to be transferred very gently to the bottom of the test tube, otherwise the semen and culture medium will mix, which is not conducive to sperm optimization.

[0023] Figure 2 for Figure 1 sectional view of . DETAILED DESCRIPTION

[0024] The present invention is further described below in conjunction with specific embodiments, but the protection scope of the present invention is not limited thereto:

[0025] Embodiment 1, a semen collection optimization cup, such as Figure 1-2 As shown, the main body is a can-shaped container made of transparent materials such as glass or acrylic, which is convenient for observing the interior of the main body and operating it.

[0026] The inner cavity of the main body is divided into two mutually isolated spaces by the same transparent material, namely, the semen collection cavity 10 and the semen optimization cavity 9, wherein the semen optimization cavity 9 is half an inverted cone, and the inclination angle of the generatrix of the cone is 45°. The structure of large upper and small lower is convenient for operating a small amount of liquid deposited at the bottom of the semen optimization cavity 9, which is used for the upstream method to optimize sperm. In the semen optimization cavity 9, a vertical flow guide tube II 8 is provided along the side wall of the main body, and the flow guide tube II 8 can be fixedly connected with the main body by bonding or the like using a glass tube. The upper end of the flow guide tube II 8 is close to the top of the semen optimization cavity 9, and the lower end is close to the bottom of the semen optimization cavity 9. When semen is added to the flow guide tube II 8 from the upper end, it can be gently retained along the flow guide tube II 8 to the bottom of the semen optimization cavity 9.

[0027] The top of the main body is closed, but a semen optimization port 5 is opened at the top of the main body corresponding to the semen optimization chamber 9, and a semen collection port 3 is opened at the top of the main body corresponding to the semen collection chamber 10, which is used for the operation of transferring semen from the semen collection chamber 10 to the semen optimization chamber 9. The semen collection port 3 and the semen optimization port 5 are sealed by a semen collection port cover 4 and a semen optimization port cover 6 respectively.

[0028] A semen collecting tube 1 is provided on the side wall of the main body where the semen collecting chamber 10 is located. The semen collecting tube 1 is located outside the main body and the inner cavity is connected to the semen collecting chamber 10, so that semen can be easily ejected from the semen collecting tube 1 into the semen collecting chamber 10. A layer of elastic silicone 11 is laid along the inner wall of the semen collecting tube 1. The elastic silicone 11 is fixedly connected to the semen collecting tube 1 by gluing or other means, and is used to stimulate the male patient to ejaculate. The semen collecting tube 1 is tilted downward (the outer port is lower than the inner port connected to the main body), and a semen collecting port cover 2 is provided on the outer port of the semen collecting tube 1 to close the semen collecting tube 1.

[0029] A guide tube I 7 is provided below the semen collecting tube 1. The guide tube I 7 is inclined upward (i.e., the guide tube I 7, the semen collecting tube 1 and the main body form an acute triangle), one end of which is connected to the inner cavity of the semen collecting tube 1, and the other end of which is connected to the semen collecting cavity 10, for collecting semen missed in the semen collecting tube 1.

[0030] A label sticker 12 is affixed to the front of the main body for marking the name of the sperm source.

[0031] The specific method of using the utility model is as follows:

[0032] 1. Write the names of the infertile couple on the label sticker 12 of the semen collection optimization cup, open the semen collection cover 2, and the male patient ejaculates semen into the semen collection cavity 10 through the semen collection tube 1, and cover the semen collection cover 2. The semen remaining in the semen collection tube 1 will flow into the semen collection cavity 10 through the guide tube 17.

[0033] 2. The staff puts the semen collection optimization cup in a 37°C constant temperature incubator for liquefaction for half an hour. After liquefaction, the staff takes the semen collection optimization cup out of the incubator and puts it on the clean workbench, opens the semen collection port cover 4 and the semen optimization port cover 6, and adds 2 ml of culture medium into the semen optimization cavity 9 through the semen optimization port 5. The culture medium is prepared by mixing serum substitute (Serum Substitute Supplement, SSS) and gamete preparation fluid (Modified HTF Medium, mHTF) in a ratio of 1:9.

[0034] Then, 0.5-1 ml of semen is sucked through the semen collection port 3 and added to the upper end of the guide tube II8. The semen will flow to the bottom of the semen optimization chamber through the guide tube II8. The semen and the culture medium are separated into two layers, and the semen is located at the bottom. The semen collection port cover 4 and the semen optimization port cover 6 are covered and placed in a 37°C constant temperature incubator for half an hour (high-quality sperm swims to the upper culture medium and is enriched therein).

[0035] 3. The staff takes out the semen collection optimization cup from the incubator again and places it on the clean workbench, opens the semen optimization cover 6, and uses a Pasteur pipette to absorb the culture medium enriched with high-quality sperm on the upper layer. The obtained sperm suspension can be used for assisted reproductive technology treatment.

[0036] Finally, it should be noted that the above examples are only some specific embodiments of the present invention. Obviously, the present invention is not limited to the above examples, and there are many variations. All variations that can be directly derived or associated with the content disclosed by a person skilled in the art should be considered as the protection scope of the present invention.
