Abstract: The invention relates to an automatically adjustable device for affixing to the nose of animals, which may be used simultaneously for administering medicinal or non-medicinal substances and/or for collecting and transmitting information about the animal by means of onboard sensors, the device being composed of a flexible support body and a pair of adjustable members that are connected by a system of swivel joints, allowing the articulation of the members in all directions. The system of swivel joints enables the adjustable members to automatically adjust to the wall of the nasal septum of each animal, which affords greater comfort and offers a larger area of contact between the face of the adjustable members of the device and the nasal mucous membrane of the animal.

Abstract: A protected follicular aspiration device containing a tube that protects the guide line providing enhanced sealing of the system, said device also having a sealing bung arrangement that forms a foam-retaining chamber preventing foam from entering the vacuum pump and a conical coupling between the guide line with the needle cannula and the sealing bung. The follicular aspiration device is intended for collecting follicles during an in vitro fertilization process, showing improvements in protecting and minimizing exposure of the collected material.

Abstract: The invention refers to a needle for follicular aspiration, having a base with a through-hole, inside of which a needle cannula is coupled, the needle cannula having a front aspiration end which protrudes from a front end of the base, and a rear end which freely protrudes from the rear end of the base, the through-hole of the base having a frustro- conical segment tapering from the rear end towards the front end of the base, forming a gap between the inner surface of the base and the outer surface of the needle cannula for coupling a biological sample collecting line.

Abstract: It refers to an artificial insemination device which comprises a tube and a tip engageable at one end of the tube, the tip being formed by a hollow tubular body with a semi-spherical upper end provided with at least three orifices; the tip internally comprises at least a first frustoconical portion tapering towards the upper end for insertion of a first vane containing biological material to be inseminated, followed by a first annular portion for coupling this vane, a second frustoconical portion tapering toward the upper end, arranged next to the first annular portion for insertion of a second vane containing biological material having a smaller diameter than the first vane, a second annular portion, arranged after the second additional frustoconical portion, for coupling with the second vane smaller than the first one, and a niche in the region of the upper semi-spherical end where the at least three orifices are arranged.
