20100179378 | Insemination catheter for artificial insemination in animals - The invention discloses an improved insemination catheter for artificial insemination in animals, characterized in which a center orifice disposed at the rear end of the nozzle for connecting the catheter tube is a blind orifice, and a diversion slit is configured between and connecting the front end of center orifice and the front end of nozzle, the diversion slit being opened when semen in the catheter tube is being squeezed and closed when semen in the catheter tube is not being squeezed. As such, the front end of the nozzle would be closed when it is inserted along with the catheter tube into the vaginal orifice of female animal body during artificial insemination such that contaminants from outside the female animal body or lubricant used will not flow into the center orifice of the nozzle, thereby enhancing the safety of artificial insemination. When the animal semen is squeezed in from the rear end of catheter tube, the diversion slit will open under pressure to allow the semen to be released smoothly, rapidly and accurately into the animal uterus, thereby enhancing the efficiency of artificial insemination. Under the circumstance where the diversion slit is closed when not under pressure, semen flown into the animal uterus or amassed around the cervix will not back flow into the center orifice of nozzle or the catheter tube, thereby reducing wasteful outflow of semen and increasing the chance of conception. | 07-15-2010 |
20100331610 | Artificial insemination device for animals - An improved artificial insemination device for animals is disclosed. The device has an inner catheter tube inserted inside a catheter tube where the front end of the inner catheter tube is closed in arc shape and its periphery is arranged with a plurality of spray release openings with arc-shaped invagination at outer edges and an extension member that communicates with the interior. As such, when the front end of the inner catheter tube enters the uterus along the cervical tract, it will not scratch the walls of cervical tract during movement because the outer edges of the spray release openings are in arc invaginated shape. When the contraction of the uterus sucks out the animal semen inside the inner catheter tube, it works like a straw through the extension members of the spray release openings, and the semen pooled together inside the catheter could be released rapidly and smoothly into different parts of the uterus to fully enhance the efficiency and the success rate of artificial insemination. | 12-30-2010 |
