INTRAUTERINE INSEMINATION CATHETER
OBJECT OF THE INVENTION. The following invention, as expressed in the title of the present specification, refers to an intrauterine insemination catheter, being of preferential utility for the intrauterine insemination of the porcine species, so that the catheter is defined by a unitary element constituted by an elongated tubular body endowed at one of its ends, in particular the end to be introduced into the animal's reproductive apparatus, of a body with a rounded surface provided with a hole as an extension of the axial hole of the tubular body. The catheter described has as a main novelty the fact of being an intrauterine insemination catheter defined by a unitary element through which access is achieved to the body and / or uterine horns, in order to carry out the deposition of the insemination dose in said place. In addition, the management of intrauterine insemination in porcine species is simplified by means of the described catheter, since, with a single act, it is possible to reach the place of deposition of the insemination dose, which in turn leads to savings in the time dedicated to such activity.
SCOPE. The present catheter for intrauterine insemination is applicable to the artificial insemination of very different animal species, and, thus, it is applicable for the insemination of the ovine species, vaccine, equine, etc., being of special application for the porcine species.
BACKGROUND OF THE INVENTION. Based on the conventional technique of artificial insemination in the porcine species, we can indicate that it consists of the introduction in the first portion of the uterine cervix of a number of sperm equal to or greater than 3000 million in an insemination volume of at least 50 my. The use of a lower number of sperm produces a decrease in fertility unless, the deposition is made in a more advanced place within the genital tract. Until now, to make the deposition in a more advanced place of the genital tract, it is only possible through anesthesia of the animal and complicated surgical techniques, being this as a consequence that, in sows, intrauterine insemination is difficult due to the presence of a cervix. relatively long and with cartilaginous folds. On the other hand, intrauterine insemination systems of swine that exist in the market are characterized by two components: a catheter glula and a flexible or semi-rigid probe. The guide catheter, in a generic way, is defined by a tubular body endowed at one of its ends, which is introduced into the genital apparatus of the animal, of a body of general conical or cylindrical shape and provided with an axial hole as an extension of the body. axial hole of the tubular body, whose guiding catheter has as its mission to find the external cervical os, enter through it and fixate on the caudal portion of the cervix. On the other hand, the different models of flexible or semi-rigid probes are introduced through the internal orifice of the guide catheter so that they come out in the light of the cervix in its intermediate portion, from there, and through the propulsive force that is exerted. from the outside, be able to travel the rest of this structure to reach the body and / or uterine horns.
DESCRIPTION OF THE INVENTION. In the present specification an intrauterine insemination catheter is described, being of preferential utility for the intrauterine insemination of the porcine species, so that the intrauterine insemination catheter is defined by a unitary element constituted by an elongated tubular body provided in one of its ends, in particular the end to be introduced into the animal reproductive system, of a rounded surface body provided with a hole as an extension of the axial hole of the tubular body. The intrauterine insemination catheter has the appropriate rigidity to access, by the end endowed with the body of rounded surface, to the body and / or uterine horns, in order to carry out the deposition of the insemination dose in said place. In this way, we obtain an intrauterine insemination catheter made up of a single component, which brings advantages of an economic nature, since the materials of which, logically, are more economical than those related to a corresponding catheter and catheter, conventional, and, in addition, its manufacture is also simpler, having an impact on its cost of production, and, consequently, on its final price. Likewise, when the intrauterine insemination catheter is constituted by a single component, the management of intrauterine insemination in porcine species is simplif since, with a single act, it is possible to reach the place of deposition of the insemination dose, which In turn, it leads to savings in the time dedicated to such activity. To complement the description that will be made next, and in order to help a better understanding of the characteristics of the invention, this descriptive report is accompanby a set of drawings, whose figures are illustrative and not limiting , the most characteristic details of the invention are represented.
BRIEF DESCRIPTION OF THE DRAWINGS. Figure 1. Shows an elevation view of an intrauterine insemination catheter, being able to observe how it is defined by tubular body topped by one of its ends by a body of generally spherical shape. Figure 2. Shows a detailed view of the generally spherical body in which the tubular body forming the intrauterine insemination catheter, object of the invention, is finished. Figure 3. Shows a detailed view of a variant of practical execution in which the body, with rounded surface, in which the tubular body forming the intrauterine insemination catheter is terminated, has an oval shape. DESCRIPTION OF A PREFERRED EMBODIMENT In view of the aforementioned figures and according to the numbering adopted, we can observe how the intrauterine insemination catheter 1 is defined by a unitary element constituted by an elongated tubular body 2 endowed at one of its ends, specifically the end to be introduced into the animal reproductive apparatus, of a body 3 with a rounded surface provided with an orifice 4 as an extension of the axial hole 5 of the tubular body 2. Thus, the body 3 with a rounded surface can be defined in different ways, and, in this way, can be defined by a generally spherical, oval body or any other similar shape having a rounded surface that facilitates its introduction into the animal reproductive system. On the other hand, the intrauterine insemination catheter 1 has the rigidity suitable to access, through the end provided with the body 3 with rounded surface, to the body and / or uterine horns, in order to materialize the deposition of the insemination dose in said place. Thus, the intrauterine insemination catheter 1, constituted by a single component, entails advantages of an economic nature, since, of course, the materials of which it consists, are more economical, and, moreover, its manufacture is also simpler, having an effect on its production cost, and, consequently, in its final price. Likewise, the intrauterine insemination catheter 1 has the added advantage that being composed of a single component, it is simplified its handling in the operation of intrauterine insemination in the porcine species, since, with a single act it is possible to reach the place of deposition of the insemination dose, which in turn leads to a saving in the time dedicated to such activity. The intrauterine insemination catheter 1 is useful for the practice of intrauterine insemination in various animal species, and thus, although it is of special application for the porcine species, it is also applicable in the ovine, equine, vaccine and other species.
