ARTIFICIAL INSEMINATION DEVICE FOR ANIMALS

Abstract

The artificial insemination device for animals comprises a cannula (1); an insertion tip (2) placed on one of the ends of the catheter (1), said insertion tip (2) having one or more holes (7); and a fixing element (3) placed on a cannula (1), wherein said fixing element (3) comprises a tubular portion (8), a first frustoconical portion (4) and a second frustoconical portion (5),

The artificial insemination device for animals according to the present invention enables, by not disturbing or hyperstimulating the animal, the cannula to reach the uterus and be fixed in the correct position in order to suitably perform post-cervical insemination in young sows.

Claims

1. An artificial insemination device for animals, comprising: a cannula (1); an insertion tip (2) placed on one of the ends of the cannula (1), said insertion tip (2) having one or more holes (7); and a fixing element (3) placed on the cannula (1), characterised in that said fixing element (3) comprises a tubular portion (8), a first frustoconical portion (4) and a second frustoconical portion (5).

2. The artificial insemination device for animals according to claim 1, wherein said first and second frustoconical portions (4, 5) are made from a flexible material.

3. The artificial insemination device for animals according to claim 2, wherein said first and second frustoconical portions (4, 5) define an end with a larger diameter (41, 51) and an end with a smaller diameter (42, 52), such that during the insertion of the cannula (1), said ends with a larger diameter (41, 51) are farther from the insertion tip (2) and during the removal of the cannula (1), said ends with a larger diameter (41, 51) are closer to the insertion tip (2).

4. The artificial insemination device for animals according to claim 1, wherein said cannula (1) comprises an indication of insertion (6).

5. The artificial insemination device for animals according to claim 3, wherein the diameter of the end with a larger diameter (41) of the first frustoconical portion (4) is smaller than the diameter of the end with a larger diameter (51) of the second frustoconical portion (5).

6. The artificial insemination device for animals according to claim 5, wherein said first frustoconical portion (4) is arranged closer to the insertion tip (2) than said second frustoconical portion (5).

Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0025] To better understand what has been set forth above, several drawings schematically depicting a practical embodiment only by way of non-limiting example are attached.

[0026] FIG. 1 is a perspective view of the artificial insemination device according to the present invention in the insertion position thereof; and

[0027] FIG. 2 is a perspective view of the artificial insemination device according to the present invention in the removal position thereof.

DESCRIPTION OF A PREFERRED EMBODIMENT

[0028] As shown in FIGS. 1 and 2, the artificial insemination device for animals according to the present invention comprises a cannula 1, which is a tubular element that is inserted in the cervix of the animal to be inseminated.

[0029] To facilitate the insertion thereof, said cannula 1 comprises on one of the ends thereof an insertion tip 2 comprising one or more holes 7 to enable the semen to exit therethrough to inseminate the animal.

[0030] To enable fixing of the cannula 1 in position during insemination, the insemination device further comprises a fixing element 3 placed on said cannula in a portion thereof.

[0031] Said fixing element 3 comprises a first frustoconical portion 4 and a second frustoconical portion 5, both frustoconical portions 4, 5 being placed in a tubular portion 8 which is that which surrounds said cannula 1 in a fitted manner.

[0032] Said frustoconical portions 4 and 5 are made from a flexible material, such that they vary their orientation based on the direction of movement of the cannula 1 and it also enables the insertion and removal of the cannula without disturbing the animal.

[0033] Said first and second frustoconical portions 4, 5 each comprise an end with a larger diameter 41, 51 and an end with a smaller diameter 42, 52 and the diameter of the end with a larger diameter 41 of the first frustoconical portion 4 is smaller than the diameter of the end with a larger diameter 51 of the second frustoconical portion 5.

[0034] Moreover, the first frustoconical portion 4 is placed closer to the insertion tip 2 than the second frustoconical portion 5.

[0035] When the cannula 1 is inserted, said first and second frustoconical portions 4, 5 are oriented as shown in FIG. 1, i.e. with the ends with a smaller diameter 42, 52 closer to the insertion tip 2 than the ends with a larger diameter 41, 51.

[0036] On the other hand, when the cannula 1 is removed, the orientation of said first and second frustoconical portions 4, 5 changes thanks to the flexible nature of the material. In other words, during the removal of the cannula, the ends with a larger diameter 41, 51 are closer to the insertion tip 2 than the ends with a smaller diameter 42, 52.

[0037] To facilitate the correct placement of the cannula 1, said cannula comprises an indication of insertion 6, shown in FIG. 1, for example, indication lines, which indicate the correct position of the cannula 1 in the insemination position, with a margin of error of, for example, 2-3 cm.

[0038] Despite the fact that reference has been made to a specific embodiment of the invention, it is evident for the person skilled in the art that numerous variations and changes may be made to the artificial insemination device for animals described, and that all the aforementioned details may be substituted by other technically equivalent ones, without detracting from the scope of protection defined by the attached claims.
