The appliance comprises a handle, a speculum tube (23) extending axially from the handle (21) as far as a distal end (22) where it has an opening (28), a video viewing system having a lens (35) arranged in the speculum tube and a transmission device (36) connected to the lens and connectable to a remote viewing screen, and a lens support (49) for keeping the lens (35) in a predetermined position with respect to the speculum tube, in which position the lens is near said opening (28) and opposite the space situated beyond said opening (28), characterized in that said speculum tube has an end part (26) and a main part (27) extending between said end part and said handle, said end part (26) being arranged around said support (49) and delimiting said opening (28), said end part (26) being elastically deformable and said main part (27) being rigid.

A sperm injection tube for artificial insemination of swine has a tube and a plug mounted on an end of the tube. The plug has a plug body, a guiding portion, and a blocking portion. The guiding portion is formed around the plug body and has multiple guiding fins near the injection hole. The blocking portion is formed around the plug body and has at least one blocking fin near the connecting hole. Each guiding fin is umbrella-shaped and flexible. When inserting the sperm injection tube into the uterus, the guiding fins are concentrated toward the plug body to led the plug to easily pass through the cervix. The blocking portion block the cervix to prevent the semen flowing out and to keep the tube from being pushed out to raise the conception rate of the sow.

Everting balloon systems and methods for using the same are disclosed herein. The systems can be configured to access and dilate body lumen and cavities. For example, the systems can be used to dilate the cervix and access the uterine cavity. The systems can also be used to occlude the cervix. The systems can also be used to occlude the urethra.

Bodily fluid collection systems are described where the system may be used for collecting and transferring sperm into a syringe. The syringe is configured to have a distal collection tip which is gently tapered or radiused to present a smooth and atraumatic surface and which is specifically configured and shaped to be inserted within and received by the collection receptacle. The distal collection tip has a shape which corresponds directly to a tapered reservoir defined at the bottom of the collection receptacle such that a distal opening defined through the tip is optimally positioned within the concentrated bodily fluid pooled within the reservoir for collection. Moreover, the gentle taper of the collection tip may present an atraumatic surface for inhibiting damage to the sperm contained within the ejaculate as the sperm is suctioned into the distal opening for insemination into the female.

In accordance with one aspect of the invention, an apparatus for depositing semen into a uterus of a mammal includes a non-linear probe portion that is curved to approximate the angle between the vagina and cervix of a mammal. The probe has a caudal end that is flared to accept a stopping device, the stopping device preventing airflow that would cause the lens of a camera to become contaminated. The probe has a plunger that passes through the length of the probe that, when activated, deposits the semen into the uterus of the mammal through an opening in the distal end of the probe. The distal end of the probe is equal to, or less than, the penis of a male of the same species that is being inseminated

An apparatus for collecting seminal fluids, and specifically an artificial cervix for collecting seminal fluids for artificial insemination, is provided herein. The cervix comprises an elongated cylindrical member having either a closed end for receiving and storing ejaculated semen or an open end for allowing ejaculate to pass through, and an open end having a rim of a diameter sufficient to receive the penis of the animal. A handle can be detachably connected to said cylindrical member that allows users to hold the cervix in the correct position during collection of the animal's seminal fluids.

The present artificial insemination instrument may include a single use, hollow, elongate, metal pipette and a single disposable syringe that is not toxic to bovine sperm. The apparatus is used with any type of diluent that is not toxic to bovine sperm. In various embodiments, a technician may use non-sorted reduced sperm count semen straws from a bull stud, cut an unsorted semen straw into several pieces to use one piece at a time per cow, thaw one straw and mix the non-sorted semen with diluent, or use reduced sperm count semen straws filled with sex sorted semen by the manufacturer. A procedure is disclosed to use the artificial insemination instrument, reduced sperm count semen from any of the aforementioned sources, a non-toxic syringe, and a diluent to achieve conception rates at least as good as conventional prior art device and procedure conception rates.

For example, the systems can be used to dilate the cervix and access the uterine cavity. The systems can also be used to occlude the cervix. The systems can also be used to occlude the urethra.

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.
