DISPOSITIVO PARA INSEMINACION ARTIFICIAL POR VIA CERVICAL DEDEVICE FOR ARTIFICIAL INSEMINATION BY CERVICAL VIA

PEQUENOS RUMIANTESSMALL RUMINANTS

DESCRIPCIONDESCRIPTION

Campo tecnico de la invencionTechnical field of the invention

La invencion pertenece a los dispositivos para inseminacion artificial. Mas concretamente, a aquellos destinados a pequenos rumiantes y que emplean la via cervical.The invention pertains to devices for artificial insemination. More specifically, to those intended for small ruminants and who use the cervical route.

Antecedentes de la invencion o Estado de la TecnicaBackground of the invention or State of the Art

Son conocidos los dispositivos de inseminacion intrauterina. Por ejemplo, WO03084584A2 se refiere a un dispositivo de inseminacion intrauterina que incluye un cateter modificado que incorpora una boquilla en un extremo y una membrana previamente enrollada o recogida en el interior del cateter. Por la presion aplicada por el semen a depositar, se desenrolla extendiendose profundamente dentro del tracto cervical. Una vez desenrollada la membrana, su extremo cede a la presion y se rompe liberando el semen en el interior del utero. Es un dispositivo complejo que requiere maniobras complicadas.Intrauterine insemination devices are known. For example, WO03084584A2 refers to an intrauterine insemination device that includes a modified catheter incorporating a nozzle at one end and a membrane previously wound or collected inside the catheter. Due to the pressure applied by the semen to be deposited, it is unrolled extending deep into the cervical tract. Once the membrane is unwound, its end yields to the pressure and breaks freeing the semen inside the uterus. It is a complex device that requires complicated maneuvers.

Se conocen otros dispositivos de inseminacion cervical como el Inyector QuickLock para ovino y caprino comercializado por Minitube GmbH® o el Cateter recto de IMV®.Other cervical insemination devices such as the QuickLock Injector for sheep and goats marketed by Minitube GmbH® or the IMV® Straight Catheter are known.

Con el avance del dispositivo por el cervix, se suelen producir heridas. Para buscar el canal por donde avanzar y superar los pliegues del cervix, se suelen realizar movimientos con la punta del cateter, que en la mayorla de los dispositivos existentes es rlgida y puede danar al animal. La reaccion inflamatoria de estas lesiones, junto con la posible salida de sangre, liberando globulos blancos que actuaran contra el semen al considerarlo un cuerpo extrano, lo cual hace menos efectiva la inseminacion reduciendo la tasa de fertilidad. Aparte de las lesiones que se puedan producir en una zona tan sensible, el procedimiento descrito es mas lento y molesto por lo que genera estres en el animal con liberacion de cortisol y otras sustancias corticoesteroides. ElloWith the advance of the device through the cervix, wounds usually occur. To find the channel through which to advance and overcome the folds of the cervix, movements are usually made with the tip of the catheter, which in most of the existing devices is rigid and can damage the animal. The inflammatory reaction of these lesions, together with the possible blood flow, releasing white blood cells that will act against the semen when considered a foreign body, which makes insemination less effective reducing the fertility rate. Apart from the lesions that may occur in such a sensitive area, the procedure described is slower and more annoying, which causes stress in the animal with the release of cortisol and other corticosteroids.

Breve descripcion de la invencionBrief Description of the Invention

A la vista de las limitaciones detectadas, serla deseable mejorar la tasa de fertilidad en procedimientos de inseminacion artificial de forma segura para el animal. Especialmente, en el caso de pequenos rumiantes.In view of the limitations detected, it would be desirable to improve the fertility rate in artificial insemination procedures safely for the animal. Especially, in the case of small ruminants.

Serla deseable llevar a cabo una tecnica mlnimamente invasiva que evitara lesiones y estres al animal. La presente invencion propone un dispositivo que consigue realizar la inseminacion disminuyendo ademas la cantidad necesaria de semen.It would be desirable to carry out a minimally invasive technique that will prevent injuries and stress to the animal. The present invention proposes a device that manages to carry out the insemination, also reducing the necessary amount of semen.

El dispositivo logra una penetracion suficientemente profunda para salvar los pliegues del cervix. Sin embargo, el dispositivo minimiza la posibilidad de lesiones.The device achieves a penetration deep enough to save the folds of the cervix. However, the device minimizes the possibility of injury.

Para lograr estas y otras ventajas, se propone un dispositivo para inseminacion artificial por via cervical de pequenos rumiantes que incluye un elemento longitudinal hueco que se estrecha conicamente hacia un primer extremo con punta roma y con orificio de salida. Dicho elemento longitudinal tiene al menos lateralmente otro segundo orificio.

La FIG. 2 muestra un ejemplo de dispositivo desde arriba.FIG. 2 shows an example of a device from above.

Descripcion detallada de la invencionDetailed description of the invention

Con referencia a las figuras, se describe un ejemplo de realizacion de la invencion. Sin caracter limitativo, la realizacion esta especialmente adaptada a pequenos rumiantes, por ejemplo preferentemente ovejas.With reference to the figures, an example of embodiment of the invention is described. Without limitation, the embodiment is especially adapted to small ruminants, for example preferably sheep.

Se sabe que el cervix de la oveja esta compuesto por una serie de pliegues irregulares entre los cuales discurre un pequeno canal, no alineado, que comunica la vagina con el utero y por el que debe avanzar el semen. Estos pliegues estan dispuestos de una forma distinta en cada animal. Ademas la apertura del cervix a la vagina esta protegida por una estructura, en forma mas o menos triangular, llamada plica.It is known that the sheep's cervix is composed of a series of irregular folds between which a small, non-aligned channel runs, which connects the vagina with the uterus and through which the semen must advance. These folds are arranged differently in each animal. In addition, the opening of the cervix to the vagina is protected by a structure, more or less triangular, called plica.

Mediante el dispositivo mostrado en las FIG. 1 y FIG. 2, la inseminacion es mlnimamente invasiva ya que solo se introduce la parte delantera del dispositivo, a traves del elemento longitudinal 1 con forma de lanza, evitando que haya reflujo hacia el exterior.By the device shown in FIG. 1 and FIG. 2, the insemination is minimally invasive since only the front part of the device is introduced, through the lance-shaped longitudinal element 1, preventing the outward reflux.

Al introducir el cateter (no mostrado) en el interior del dispositivo, la base 2, que es de forma semiesferica alrededor del elemento longitudinal 1, contacta y presiona exteriormente contra el cuello del utero. A su vez, la base 2 tiene una porcion rebajada o achatamiento lateral 21 que tiene una doble funcion. Le sirve al tecnico para mejorar la vision durante la maniobra. Ademas sirve para salvar la plica del cuello del utero. Esto facilita dirigir el cateter y colocarlo en el cervix salvando la plica y dejando el cuello sellado, de forma que solamente se introduzca dentro del mismo el elemento longitudinal 1 del dispositivo, resultando una penetracion nada invasiva.Upon inserting the catheter (not shown) into the device, the base 2, which is semi-spherical about the longitudinal element 1, contacts and presses externally against the cervix. In turn, the base 2 has a lowered portion or lateral flattening 21 that has a double function. It helps the technician to improve vision during the maneuver. It also serves to save the cervical plica. This facilitates directing the catheter and placing it in the cervix saving the plica and leaving the neck sealed, so that only the longitudinal element 1 of the device is inserted into it, resulting in a non-invasive penetration.

Al disponer el dispositivo ademas del orificio extremo 11, de otros dos orificios 12 situados lateralmente (a 5 mm del extremo) se consigue que, si alguno de ellos queda tapado por el contacto con un pliegue del cervix, el semen pueda salir por los restantes. La disposition asegura que siempre quede algun orificio libre para el semen. Debido a las reducidas dimensiones de estos orificios (0,5 mm - 2 mm) y al angulo de salida (45°) con el que se han disenado se consigue que el semen sea proyectado a alta velocidad por tres orificios simultaneamente, lo que facilita que el semen progrese mas alla del segundo pliegue que es el mas problematico.By arranging the device in addition to the end hole 11, two other holes 12 located laterally (5 mm from the end) it is achieved that, if any of them is covered by contact with a fold of the cervix, the semen can leave the remaining . The provision ensures that there is always some free hole for semen. Due to the small dimensions of these holes (0.5 mm - 2 mm) and the exit angle (45 °) with which they have been designed, the semen is projected to be projected at high speed by three holes simultaneously, which facilitates that the semen progress beyond the second fold that is the most problematic.

En suma, el dispositivo mostrado tiene entre otras, las siguientes ventajas:In sum, the device shown has, among others, the following advantages:

• Evitar reflujo del semen desde el cervix a la vagina, adaptandose a la anatomla de la oveja, especialmente al anillo de entrada cervical y a la protection de la plica.• Avoid semen reflux from the cervix to the vagina, adapting to the anatomy of the sheep, especially the cervical entry ring and the protection of the plica.

• Facilitar la vision y tarea del tecnico durante la realization de la insemination.• Facilitate the vision and task of the technician during the realization of the insemination.

• No modificar el procedimiento actual ni los instrumentos que se utilizan actualmente en la inseminacion.• Do not modify the current procedure or the instruments that are currently used in the insemination.

• Salvar el segundo pliegue del cervix.• Save the second fold of the cervix.

• No danar al animal.• Do not harm the animal.

En Las pruebas realizadas in vivo, se ha constatado un aumento de 15 puntos en la tasa de exito de fertilidad con respecto a los medios convencionales. El dispositivo empleado tenia las siguientes dimensiones: diametro exterior de la base de 12 mm y una altura total de 23 mm.In the tests carried out in vivo, there has been a 15-point increase in the fertility success rate with respect to conventional means. The device used had the following dimensions: external diameter of the base of 12 mm and a total height of 23 mm.

El dispositivo ha sido disenado para ser un elemento mas dentro del instrumental utilizado actualmente, no se requiere de ninguna adaptation en este material ya que es compatible con los cateteres existentes.The device has been designed to be an element within the instruments currently used, no adaptation is required in this material as it is compatible with existing catheters.

Tampoco es preciso formation adicional para el tecnico, ya que este hara la operation como venla haciendola con anterioridad. Incluso se facilita la maniobra y se reduce el tiempo necesario para la inseminacion, al no tener necesidad de buscar la mas minima penetration. Unicamente tendra que incorporar el dispositivo al cateter, para ello, se ha dispuesto un canal 22 que sirve de alojamiento para el cateter cuya forma troncoconica se extiende hasta el elemento longitudinal 1 de tal manera que al tener una section que va disminuyendo puede adaptarse a cateteres de distintos diametros.Nor is additional training required for the technician, since he will do the operation as he has done before. It even facilitates the maneuver and reduces the time necessary for insemination, having no need to seek the smallest penetration. Only the device will have to be incorporated into the catheter, for this purpose, a channel 22 has been provided that serves as a housing for the catheter whose trunk shape extends to the longitudinal element 1 such that by having a section that is decreasing it can adapt to catheters of different diameters.

A diferencia de otras especies, en el caso particular del ganado ovino, la inseminacion debe ser muy economica para que resulte atractiva. Fundamentalmente, porque lasUnlike other species, in the particular case of sheep, insemination must be very economical to be attractive. Fundamentally, because the

tasas de exito son inferiores a otras especies y por el propio valor economico en el mercado del animal, en comparacion con otros como el cerdo o la vaca.Success rates are lower than other species and for their own economic value in the animal market, compared to others such as pig or cow.

Otro aspecto interesante para que pueda ser utilizado tanto para ganado ovino como en otras especies, es la posibilidad de poderse fabricar en una sola pieza. Por 5 ejemplo, mediante inyeccion de plastico. Estas caracterlsticas hacen que su coste de fabrication sea bajo. Hay que tener en cuenta que este dispositivo debe ser preferiblemente desechable. Su reutilizacion puede ocasionar la transmision de enfermedades entre diferentes animales y la esterilizacion del mismo, serla un proceso muy caro y poco practico para este tipo de operaciones.Another interesting aspect so that it can be used for both sheep and other species, is the possibility of being manufactured in one piece. For example, by plastic injection. These features make your manufacturing cost low. Keep in mind that this device should preferably be disposable. Its reuse can cause the transmission of diseases between different animals and its sterilization, it would be a very expensive and impractical process for this type of operations.
