Abstract
Description
Catéter para inseminación artificial.Catheter for artificial insemination.
La presente invención se refiere a un catéter concebido para facilitar la inseminación artificial de animales, en especial de ganado porcino.The present invention relates to a catheter designed to facilitate artificial insemination of animals, in Special pigs.
Es objeto de la invención que el catéter incorpore un terminal de geometría optimizada para facilitar su entrada sencilla a presión vía vaginal y que quede acoplado en el cuello del útero impidiendo la salida de semen al exterior.It is an object of the invention that the catheter incorporate an optimized geometry terminal to facilitate your simple entry to vaginal pressure and that is coupled to the cervix preventing semen outflow.
Es asimismo objeto de la invención que el terminal disponga de medios de rigidización que adapten su elasticidad en orden a optimizar el efecto tapón que evita el reflujo seminal.It is also the object of the invention that the terminal has stiffening means that adapt its elasticity in order to optimize the stopper effect that prevents seminal reflux.
La aplicación de la dosis seminal en las cerdas en celo se realiza de forma rutinaria, por vía vaginal y sirviéndose de un instrumento denominado catéter. Este catéter es un útil tubular, que aunque puede presentar diferentes formas, en todos los casos sirve para alcanzar el cuello del útero y fijarse en sus 3-4 primeros centímetros, como lo hace un tornillo en una tuerca, permitiendo la aplicación a su través de la dosis seminal, que tiene que atravesar el resto del cuello uterino y aproximadamente otros 15 centímetros hasta llegar al cuello del útero.The application of the seminal dose in the sows in heat is performed routinely, vaginally and using an instrument called a catheter. This catheter is a tubular tool, which although it can have different forms, in All cases are used to reach the cervix and fix in its first 3-4 centimeters, as does a screw in a nut, allowing the application through the seminal dose, which has to go through the rest of the cervix and approximately another 15 centimeters to reach the neck of the uterus.
Existen en la actualidad diferentes tipos de catéteres que van desde el clásico reutilizable tipo "Melrose" fabricado en una sola pieza en caucho o similar y que guarda un gran parecido con el pene del berraco, pasando por una casi inagotable lista de catéteres de plástico de un solo uso.There are currently different types of catheters ranging from the reusable classic "Melrose" type manufactured in one piece in rubber or similar and that keeps a great resemblance to the cock of the berraco, going through an almost inexhaustible list of single-use plastic catheters.
Éstos últimos están constituidos generalmente por tres piezas, mango, caña y punta.The latter are generally constituted by three pieces, handle, cane and tip.
El mango, no presente en todos los catéteres, es una pieza de pequeñas dimensiones que sirve para manejar el catéter con facilidad y, en los que lo poseen, para fijar al catéter la canulita del envase seminal.The handle, not present in all catheters, is a small piece that serves to handle the catheter with ease and, in those who own it, to fix the catheter canulite of the seminal container.
La caña o cuerpo del catéter, es un tubo de aproximadamente 50 centímetros de largo, que sirve como conducción de líquido seminal. El diámetro de este tubo es variable, aunque en ningún caso su cota exterior supera los 10 milímetros.The rod or body of the catheter is a tube of approximately 50 centimeters long, which serves as a driving of seminal fluid. The diameter of this tube is variable, although in no case its outer dimension exceeds 10 millimeters.
La punta, elemento principal del catéter es una pieza de tamaño y forma variable, que en cualquier caso posibilita su introducción y fijación en el cuello del útero. Las hay de forma cilíndrica (tapón), fabricadas en espuma y de un tamaño próximo a los 2 centímetros, y que se introducen por presión, y las hay con forma cónica, fabricadas con diferentes tipos de plásticos y con tamaños muy variables pero que suelen situarse entre los 3 y 8 centímetros y que se introducen con movimientos de atornillado en sentido contrario a las agujas del reloj. La sujeción al cuello del útero se facilita en unos casos gracias a la forma helicoidal del cono y en otros casos a la existencia de unos anillos o láminas suplementarias que aumentan el nivel de acoplamiento entre el catéter y las irregularidades de la pared cervical.The tip, the main element of the catheter is a piece of variable size and shape, which in any case allows its introduction and fixation in the cervix. There are so cylindrical (cap), made of foam and of a size close to the 2 centimeters, and that are introduced by pressure, and there are them with conical shape, manufactured with different types of plastics and with very variable sizes but usually between 3 and 8 centimeters and that are introduced with screwed movements in counterclockwise. The fastening to the neck of the uterus is facilitated in some cases thanks to the helical shape of the cone and in other cases the existence of rings or sheets supplements that increase the level of coupling between the catheter and irregularities of the cervical wall.
El catéter para inseminación artificial que constituye el objeto de esta invención cumple las expectativas expuestas mediante la incorporación de un terminal que permite su introducción a presión sin necesidad de recurrir al atornillado. Se propone un terminal que se introduce a través de la vagina del animal a presión hasta fijarse en el cuello del útero con la colaboración de unos anillos redondeados.The artificial insemination catheter that constitutes the object of this invention meets expectations exposed by incorporating a terminal that allows its introduction to pressure without resorting to screwing. Be proposes a terminal that is introduced through the vagina of the pressurized animal until it is fixed on the cervix with the collaboration of rounded rings.
El catéter comprende el terminal y un cuerpo tubular, que ajusta por unos de sus extremos en el interior del terminal, por el que circula la dosis seminal suministrada normalmente desde una bolsa que se ajusta a la embocadura del otro extremo del cuerpo tubular. El terminal dispone por tanto un primer tramo interior cilíndrico habilitado para el acoplamiento del cuerpo tubular y un segundo tramo, asimismo cilíndrico de menor diámetro que el primero, a través del que sale la dosis seminal hacia el cuello del útero.The catheter comprises the terminal and a body tubular, which adjusts at one of its ends inside the terminal, through which the seminal dose supplied circulates normally from a bag that fits the mouth of the other end of tubular body. The terminal therefore has a first cylindrical inner section enabled for the coupling of tubular body and a second section, also cylindrical of smaller diameter than the first, through which the seminal dose comes out towards the cervix.
Exteriormente el terminal está configurado a base de una serie de anillos circulares espaciados, paralelos entre sí y perpendiculares a los tramos interiores, que disponen su contorno redondeado y se distribuyen con diferentes diámetros desde la extremidad anterior del terminal hasta su extremidad posterior mostrando un perfil simétrico a modo de sinusoide.Externally the terminal is configured to base of a series of spaced circular rings, parallel to each other and perpendicular to the inner sections, which have their contour rounded and distributed with different diameters from the anterior extremity of the terminal to its posterior extremity showing a symmetric profile as a sinusoid.
Visto de perfil el terminal de catéter comprende un sector anterior convexo constituido por anillos paralelos, de diámetros progresivamente crecientes hasta un punto a partir del cual disminuyen, prolongándose a continuación un sector intermedio cóncavo, desde el que se extiende hacia atrás un sector posterior convexo de anillos con diámetros inicialmente crecientes hasta un punto a partir del cual decrecen.Seen in profile the catheter terminal comprises a convex anterior sector consisting of parallel rings, of progressively increasing diameters up to a point from which decrease, then prolonging an intermediate sector concave, from which a posterior sector extends backwards convex rings with initially increasing diameters up to a point from which they decrease.
Esta forma sinusoidal del terminal permite la introducción a presión de forma sencilla del terminal hasta el cuello del útero, su fijación, al adaptarse perfectamente a los mamelones del cervix, la estimulación de la motilidad uterina y la reducción de la cantidad de semen refluido al exterior.This sinusoidal form of the terminal allows the easily pressurized from the terminal to the cervix, its fixation, to adapt perfectly to the cervix mamelons, uterine motility stimulation and reduction of the amount of semen refluxed abroad.
Una vez que el terminal queda fijo y se procede a la introducción de la dosis seminal, los anillos constitutivos del sector anterior han quedado apoyados en las paredes del cervix impidiendo la posible salida del semen hacia el exterior, en especial la salida se ve dificultada por el anillo de mayor diámetro del sector anterior.Once the terminal is fixed and proceeds to the introduction of the seminal dose, the constitutive rings of the anterior sector have been supported on the cervix walls preventing the possible outflow of semen to the outside, in special the exit is hindered by the larger diameter ring from the previous sector.
El terminal incorpora una serie de nervios de rigidización axiales dispuestos entre las láminas e uniformemente distribuidos que permite adaptar el diámetro del terminal al del cuello del útero al asegurar que las laminas siempre queden lo más extendidas posible, asegurándose, de esta manera, la máxima reducción del reflujo seminal y la mayor estimulación del cuello uterino que al ver aumentadas sus contracciones mejora el transporte seminal hacia el cuerpo y cuernos uterinos.The terminal incorporates a series of nerves of axial stiffness arranged between the sheets and evenly distributed that allows adapting the diameter of the terminal to the cervix to ensure that the laminae always remain the most extended possible, ensuring, in this way, the maximum reduction of seminal reflux and increased neck stimulation uterine that seeing increased contractions improves transport seminal towards the body and uterine horns.
