Definitions

  • the object of the invention is an artificial vagina intended for collecting semen to be used in animal breeding, the apparatus comprising at least a tubular interior consisting of resilient rubber or equivalent material.
  • the correct temperature of the artificial vaginas used as aids in collecting semen is of crucial importance when the stallion is serving. Presently, this is achieved by heating the vagina by pouring hot water (about 50-57°C) inside it. Air can also be added to the artificial vagina for - tightening the vagina.
  • the disadvantage of the foregoing known method is that holding the artificial vagina is strenuous and dangerous, because when the stallion jumps on the breeding mount, it moves its legs vigorously, thus causing a dangerous situation for the persons holding the artificial vagina and funnel.
  • One of the disadvantages of the presently used method is that the solidly fixed artificial vagina does not follow the movements of the stallion's penis unless the artificial vagina is held by hand. This is one of the reasons why some stallions do not ejaculate into an artificial vagina.
  • the inner diameter of presently used artificial vaginas can be changed in two ways. Either different sizes of vaginas are kept in store, or the amounts of air and water contained by the water-filled vagina are changed. In the first case, the method is inconvenient and expensive, because there must be several different sizes of vaginas and numerous different spare parts for them. With water-filled artificial vaginas, on the other hand, one would have to be familiar with the stallions to be able to anticipate the amount of warm water, because once serving has started, the size of the artificial vagina can no longer be changed. Adding water to the artificial vagina also tends to change the inner shape of the artificial vagina, because the mass of water pushes the vagina opening towards the lower edge of the vagina.
  • the aim of the present invention is to eliminate the foregoing problems and to achieve a new artificial vagina, by means of which the above disadvantages are eliminated.
  • the artificial vagina comprises a heatable jacket tube, to the ends of which is fastened the tubular inner part co ing inside it, and a connection for introducing air between the jacket tube and the interior part to form an air layer, and for adjusting the thickness of this air layer for heating and using the artificial vagina.
  • a padded ring encircling the outward-directed end of the jacket tube, and at the other, inward-remaining end of the jacket tube, there is a hollow stimulation ring made of rubber or other resilient material inside the jacket tube, the amount of air in the interior air duct of the stimulation ring being adjustable through the connection, for heating and using the artificial vagina.
  • the interior part passes around the padded ring and stimulation ring, over the ends of the jacket tube, for fastening.
  • an underpressure is created in the air layer and air duct through the connections before serving takes place, so that the interior part presses at least for the most part against the interior surface of the jacket tube to heat the interior part quickly to the required temperature by means of the heating elements, and after this, air is supplied through the connections to the air layer and the air duct for adjusting the interior part and the size of the stimulation ring to suit each serving animal separately.
  • the temperature of the air layer and interior part is maintained correct by means of the heating elements at least for the duration of the possible preparation period, and towards the end or at the end of serving, the pressure in the air layer is lowered if necessary in order to facilitate the animal releasing itself from the artificial vagina.
  • the movement of the artificial vagina resembles natural flexibility, and the safety of the assisting personnel and of the serving stallion are improved.
  • the artificial vagina is used either fastened to a dummy animal or breeding mount, or alternatively manually as a separate device.
  • Figure 1 shows the artificial vagina relating to the invention for facilitating the collection of the semen of a breeder.
  • Figure 2 shows the heating stage of the artificial vagina.
  • Figure 3 shows the section III-III of figure 1.
  • Figure 4 shows the structure of the jacket tube of the artificial vagina as seen from the front and in partial cross section.
  • Figure 5 shows the apparatus relating to the invention when placed in the dummy horse, as seen from the side and in partial cross section.
  • Figure 1 shows the artificial vagina 13 relating to the invention for facilitating the collection of the semen of a breeder.
  • the main parts of the artificial vagina 13 are an aluminium jacket tube 18, and the heating elements 23 and 23' fastened on its outer surface.
  • the other end of the jacket tube 18, the vagina opening 54 of the artificial vagina 13 is encircled by a padded ring 55 made from resilient material, and at the opposite end of the artificial vagina 13, to the rear part 50 of the artificial vagina on the interior surface of the jacket tube 18, is fastened a ring-like, air-filled stimulation ring 56 provided with an interior air duct 41'.
  • the outer surface of the jacket tube 18 is covered with a tight rubber-like material 29 which repels humidity and dirt.
  • the interior surface of the jacket tube 18 of the artificial vagina 13 is covered with a soft, resilient rubber film 25, which at the same time covers the padded ring 55 and the stimulation ring 56, and the end edges of which are turned over the jacket tube of the vagina 13.
  • the rubber film 25 can be changed when necessary.
  • Over the rubber film 25, through the artificial vagina 13, is in addition pulled a protective, disposable film 26 which is changed after each serving. Disposable protectors raise the level of hygiene and thus the risk of, for example, venereal disease infections between different stallions is avoided when using a common artificial vagina.
  • Compressed air is added between the jacket tube 18 and the rubber film 25 through a valve 60, thus making the resilience of the surface of the rubber film 25 steplessly adjustable and as soft as possible. Since the temperature of the interior surface of the artificial vagina 13 should correspond accurately to the temperature of a natural vagina, the air layer 41 inside the jacket tube 18 is heated by means of heating elements 23, 23' to exactly the desired temperature.
  • the shape of the interior surface of the artificial vagina 13 is changed by changing the pressure of the air layer 41 between the jacket tube 18 of the artificial vagina and the rubber film 25 through the valve 60.
  • the size of the artificial vagina 13 should correspond as well as possible to that of the stallion's penis, and the size of the artificial vagina 13 can be steplessly adjusted also after serving has started, and during it.
  • the shape of the interior surface of the artificial vagina 13 remains as natural as possible, although its diameter changes.
  • the formed padding rubber covering the rear part of the interior surface of the jacket tube 18 of the artificial vagina 13, that is, the stimulation ring 56, has for its part a stimulating effect on the stallion's penis.
  • the shape of the stimulation ring 56 is changed by changing the pressure of the air inside the ring in the air duct 41', by means of the valve 60'.
  • the stimulation ring 56 By means of the stimulation ring 56, the obtaining of an erection in serving is significantly improved.
  • the stallion often has difficulties in pulling its penis out of the artificial vagina 13, particularly if for some reason ejaculation does not take place, the penis thus remaining swollen and stiff.
  • the size of the artificial vagina 13 can be adjusted so as to be larger when serving has ended, which is particularly important for the safety of the stallion.
  • the size of the artificial vagina 13 - the diameter of the interior surface - can be enlarged towards the end of serving by removing the air from between the jacket tube 18 and the rubber film 25, and from inside the stimulation ring 56.
  • To the outer surface of the artificial vagina 13 is in addition fastened a support element 70 against which the locking bolt 16 holding the artificial vagina in place leans. All the functions of the artificial vagina 13 are monitored and controlled from a separate monitoring room located at a safe distance.
  • Figure 2 shows the heating stage of the artificial vagina 13.
  • the heating elements 23 on the outer surfaces of the jacket tube 18 heat the metal jacket 18.
  • the jacket 18 is heated, the heat released transfers to the air layer between the jacket 18 and the rubber film 25, and from there further to the rubber film 25.
  • the temperature of the rubber film 25 of the artificial vagina 13 remains lower than that of the jacket tube 18, and it must be possible to raise the temperature of the rubber film 25 rapidly to serving temperature.
  • underpressure is utilized in heating the artificial vagina 13.
  • the rubber film 25 is sucked by underpressure through the valve 60 into contact with the jacket tube 25, thus heating the film 25 rapidly to the correct temperature.
  • underpressure is sucked through the valve 60' into the air duct of the stimulation ring 56 covering the interior surface of the jacket tube 18 of the artificial vagina 13, and the transfer of heat over the entire interior surface of the artificial vagina 13 is thus made more efficient.
  • the underpressure is changed to a preset overpressure, thus adjusting the size of the artificial vagina 13 automatically to the right size.
  • the overpressure in the artificial vagina 13 is changed to underpressure, and the rubber film 25 and stimulation ring 56 are again sucked into contact with the jacket tube 18.
  • the inner diameter of the artificial vagina 13 can be changed throughout serving.
  • Figure 3 shows the sectional view III-III of figure 1.
  • the main parts of the artificial vagina 13 are the aluminium jacket tube 18, and the heating elements fastened on its outer surface.
  • the outer surface of the jacket tube 18 is covered with a tight rubber-like material 29 which repels humidity and dirt.
  • the interior surface of the jacket tube 18 of the artificial vagina 13 is covered with a soft, resilient rubber film 25, which at the same time covers the padded ring and the stimulation ring, and the end edges of which are turned over the artificial vagina 13.
  • an air layer 41 Between the jacket tube 18 and the rubber film 25 is formed an air layer 41, which makes the resilience of the surface of the rubber film 25 steplessly adjustable and as soft as possible.
  • the pressure of the air layer 41 between the jacket tube 18 and rubber film 25 is changed.
