Sperm ascending device for sperm optimization

Abstract

The invention discloses a sperm ascending device for sperm optimization. The device is characterized by comprising an ascending pipe, an upper connecting pipe, a lower connecting pipe and a sperm pipe which are detachably connected sequentially from top to bottom, wherein the upper end of the ascending pipe is sealed; the lower end of the ascending pipe is communicated with the upper connecting pipe; the lower end of the sperm pipe is sealed; the upper end of the sperm pipe is communicated with the lower connecting pipe; a first sector plate is fixedly arranged at an inner wall of the upper connecting pipe; a second sector plate complementary to the first sector plate is fixedly arranged at an inner wall of the lower connecting pipe; when the first sector plate and the second sector plate are at least overlapped partially, the upper connecting pipe is communicated with the lower connecting pipe; when the first sector plate and the second sector plate are complementary on the same horizontal plane so as to be connected into a circular shape, a closed passage is formed between the upper connecting pipe and the lower connecting pipe. The sperm ascending device for sperm optimization has the advantages of simple structure, good separating effect and high repeatability.

Description

technical field [0001] The invention relates to the field of assisted reproduction, in particular to a sperm upstream device for sperm optimization. Background technique [0002] High motility sperm is an important guarantee for successful conception. Therefore, in the field of assisted reproduction, semen samples are generally pretreated during sperm preparation to screen out sperm with higher motility. At present, in assisted reproductive technology, the sperm upstream method is commonly used, using an ordinary 5ml round bottom test tube, first add 1-2ml of upstream liquid, and slowly add the sperm precipitate after washing and centrifugation to the bottom of the round bottom test tube; or add 1ml of semen Place it at the bottom of the test tube and add 1-2ml of upstream solution above the liquid level; or carefully add 1ml of semen to the bottom of the upstream solution, keeping the interface of the liquid. Incline the test tube at 45°, incubate at 37°C for 30-60 minute...

AI Technical Summary

Problems solved by technology

[0003] As mentioned above, the possible problems of the traditional upstream method are: the separation layer has relatively high requirements for the operator, and air bubbles may be generated, which can easily disturb the semen-culture solution separation layer, or directly bring the lower layer of semen to the upper layer, thus affecting the final separation. Due to the difference in technical proficiency among operators, the separation effect of the same semen sample may be significantly different, which will eventually affect the fertilization process of sperm and eggs, and the fertilization may have potential effects on the development of embryos
