Abstract:
A device for artificial insemination of pigs comprising:a catheter having a front end and a rear end, the catheter comprising a tubular elongated flexible element; a widening tip at the front end of the catheter, the widening tip being helical with respect to a side surface thereof; a tubular element at the rear end of the catheter, the tubular element of larger diameter than the catheter and having a handle for support; and a cannula within the tubular elongated flexible element of the catheter, the cannula being capable of being longitudinally fixed to the inside of the tubular elongated flexible element of the catheter with a tight fit, the cannula being capable of emerging through a first outlet that serves as the rear end of the catheter, the cannula having a front end in the shape of a sphere or rounded point, the diameter of which is approximately equal to or slightly greater than the diameter of the cannula and approximately equal to or less than the diameter of the inside of the tubular elongated flexible element of the catheter, the sphere or rounded point acting as a lid for closing the front end of the cannula and being suitable for movement along the length of the uterine neck of the pig until the uterine horns without eroding or damaging the mucus of the pig, wherein, at a short distance away from the lid there is a gentle narrowing of the diameter of the cannula, forming a depression in which there are two lateral orifices that connect the inside of the cannula with the outside, equipped for depositing semen into the body of the uterus of the pig to be inseminated.
