Description

Technical Field

[0001] The utility model relates to the technical field of semen conveyors, and more specifically, to a controllable expansion type semen conveyor. Background Art

[0002] A semen transfer device is an instrument used to assist in pushing sperm to the female's cervix to increase the chance of pregnancy. In order to make up for the defects of some patients with asthenospermia, a semen transfer device is often used to assist in pushing sperm to the female's cervix to increase the chance of pregnancy.

[0003] Currently available semen transporters often include a sperm storage sac and a sperm collection sleeve consisting of a sperm storage sac and a sperm collection sleeve, a zoom device that can be opened and closed to release or accommodate the sperm storage sac, a locking clamp that can be opened and closed to release or accommodate the zoom device, and a shell. An ejection device is provided in the shell, and the ejection device is used to make the locking clamp and the zoom device close to accommodate the zoom device and the sperm storage sac respectively, or to make the locking clamp and the zoom device open to release the zoom device and the sperm storage sac respectively and push the sperm storage sac to the female's cervical opening, so as to achieve the purpose of pushing sperm to the female's cervical opening.

[0004] After the existing device is inserted into the female cervix, the expansion structure directly pushes the splint by controlling the telescopic rod to expand the female cervix. The expansion size of the expansion rod cannot be controlled and there is no buffer, which can easily cause pain and injury to the user, affecting the user's physical health and user experience. In addition, the shape of the existing fertility aid is straight, which is not easy to operate. Utility Model Content
