Patent

CA 2365080

It comprises a tube or catheter (1) that is introduced into the animal's vagina up to the cervix duct (19); characterized in that it additionally comprises a flexible probe (6) constituted of a first flexible tubular body (12), and the outside of which is covered by a layer of a flexible material; all to allow that the probe, after reaching the distal end of the tube (1), may progress through the cervix duct (19) and thereafter through the cervix horn (22). This structure allows to introduce a fluid with spermatozoids, embryos or therapeutic solutions to the anterior third of the uterus horn, or to obtain embryos from the anterior portions of the uterus horn, and all this without sedation or anesthesia and without disturbing the animal's well-being. To facilitate obtaining embryos, the probe includes an elastic small external coating (28) that is inflated through a flexible tube (27) for adapting itself to the uterus horn (22) preventing refluxes when carrying out absorption. It is essentially applied to porcine livestock, small ruminants and any other animal species.

L'invention concerne un dispositif comprenant un tube ou cathéter (1) que l'on introduit dans le vagin de l'animal jusqu'au conduit cervical (19), se caractérisant également par une sonde flexible (6) constituée d'un premier corps tubulaire flexible (7) à l'intérieur duquel se trouve au moins un conduit flexible (12), et dont l'extérieur est recouvert d'une couche (8) de matière flexible, tout ceci afin que la sonde, après avoir atteint l'extrémité distale du tube (1), avance dans le conduit cervical (19), puis dans la corne utérine (22). Cette structure permet d'introduire un fluide avec des spermatozoïdes, des embryons ou des solutions thérapeutiques dans le tiers antérieur d'une corne utérine, ou d'obtenir des embryons des parties antérieures de la corne utérine, tout ceci sans sédation ou anesthésie, et sans perturber le bien-être de l'animal. Afin de faciliter l'obtention d'embryons, la sonde comprend un petit revêtement extérieur élastique (28) que l'on gonfle au moyen d'un tube flexible (27) de façon à l'adapter à la corne utérine (22), prévenant les reflux au moment de l'absorption. L'invention concerne, en particulier, les porcins, les petits ruminants, et toute autre espèce animale.
