ABSTRACT:
An improved animal-use artificial inseminator comprised of an insemination tube with a nozzle at its front extremity into which an insemination sheath is inserted and a connector at the rear extremity of the insemination tube having a check membrane. After the insemination tube penetrates the female animal body vagina and the front end of the nozzle is nominally at the first cervical ring of the cervix, the semen bottle insertion tube is utilized to pierce the connector check membrane at the rear extremity of the insemination tube and when the semen at the insemination tube is squeezed, semen is automatically squeezed out of the insemination sheath. The soft insemination sheath proceeds along the cervix without the occurrence of friction, the front end smoothly moving forward until it reaches the position of the womb. Contractions of the womb are utilized to articulate the insemination sheath such that the contained semen is ejaculated into the two Fallopian tubes or the womb from the slits along the two sides of the front end. At the same time, after the semen bottle is pulled out, since the connector check membrane automatically opens and closes along with the contraction of the womb, not only is the semen in the insemination sheath prevented from backflow or leakage, but air is admitted for smooth and complete squeezing into the Fallopian tubes or the womb.
