Definitions

  • the present invention relates to an improved artificial insemination device with an inner catheter for animals, more particularly, a simple, practical, ideal and inventive device that is easy and convenient to use and allows animal semen to reach the two ducts to uterine horns or the uterus swiftly and smoothly, thereby improving the success rate of artificial insemination and effectively saving the amount of semen needed.
  • the invention herein requires minimal amounts of insemination semen and offers economic benefit. It also renders artificial insemination safer, more hygienic, and more humane.
  • FIG. 1 and FIG. 2 typically comprises a plastic catheter tube 10 of certain hardness and a nozzle 20 made of softer material installed protrusively on the front end of catheter tube 10.
  • the catheter tube 10 and nozzle 20 are inserted along the vagina 11 of female animal body 1 until the nozzle 20 at the front penetrates into cervical tract 12.
  • the insertion tube 31 of the semen dispenser (bag or syringe) 30 containing the animal semen is inserted into the rear end of catheter tube 10, and as the operator continuously squeezes the semen dispenser (bag or syringe) 30, the semen contained therein is ejected into the cervical tract 12 through the nozzle 20 of catheter tube 10, where the uterus 13 contracts to draw in semen from cervical tract 12.
  • such devices include an Al Buddy 40, an elastic saddle-like apparatus resembling the two front legs of an animal, wherein a connector 50 with open posterior is installed at the rear end of catheter tube 10, with a positioning strap 41 disposed between the Al Buddy 40 and the connector 50; as such, during the artificial insemination procedure, the operator straddles the Al Buddy 40 over the back of the female animal 1 such that the female animal feels that a male animal has mounted with its two front legs, a guide bush 60 is then placed at the vaginal orifice 111 of female animal body 1 and after the catheter tube 10 and nozzle 20 penetrate the vagina 11 and reaches the cervical tract 12 through the guide bush 60, the rear end of catheter tube 10 is flexed upward and directly secured by the positioning strap 41 connected to the Al Buddy 40; following the ingress of a semen dispenser 30 insertion tube 31 into the connector 50, the operator only has to squeeze the semen dispenser 30.
  • FIG. 4 and FIG. 5 U.S. Patent No.6526917
  • the front end opening 421 of catheter tube 420 is inserted into a sheath-like membrane 410 and the leading edge 412 of membrane 410 is snapped into a positioning ring 422 of catheter tube 420.
  • nozzle 440 is inserted into the front end of catheter tube 420 to immobilize membrane 410.
  • the various components including the member 410 sandwiched between nozzle 440 and catheter tube 420 can be further secured to each other by sonically welded or heat staked.
  • the object of such artificial insemination assembly is to cause the tip 411 of sheath-like membrane 410 to begin unfolding in an inside-out manner not unlike removing one's sock by pulling from the open end when semen is squeezed into the rear end of catheter tube 420 and enters the uterus along the cervical tract where semen is ejected from the opening of tip 411 to enhance the efficiency of insemination, prevent the entry of contaminants into uterus, and prevent the backflow of semen.
  • Such artificial insemination apparatus is more effective in comparison with prior art. But it still has some drawbacks in actual implementation:
  • FIG. 6 and FIG. 7 depict another artificial insemination apparatus for animals, characterized in which a longer plastic inner catheter 70 is movably inserted in the catheter tube 10 of a conventional device that comes with a nozzle 20, and a smaller second nozzle 80 is disposed at the forward portion of inner catheter 70.
  • the object of such artificial insemination assembly is to allow the operator to advance the smaller inner catheter 70 inside the catheter tube 10 more smoothly along the cervical tract and bring the smaller second nozzle 80 to the location of uterus after the catheter tube 10 and nozzle 20 enter the cervical tract of female animal body and the nozzle 20 reaches the first cervical ring.
  • semen contained in the semen dispenser (bag or syringe) is expelled from the rear end of inner catheter and enters uterus smoothly via the second nozzle 80.
  • the semen dispenser bag or syringe
  • such design facilitates the delivery of semen to the uterus and the use of smaller inner catheter 70 saves the volume of semen required.
  • Still operators find some deficiencies with the device after using it in actual operations. That is, when the inner catheter is extended inward, operator is unable to see if the second nozzle 80 at the front has reached the uterus and can only rely on experience to control the depth of inward extension. What happens most frequently in actual implementation is that the inner catheter 70 overextends and injures the uterus.
  • the primary object of the present invention is to provide an improved artificial insemination device with an inner catheter for animals, characterized in which a thin flexible tube is disposed inside the front end of inner catheter, which extends automatically forward and outward when semen is squeezed into the inner catheter.
  • a thin flexible tube is disposed inside the front end of inner catheter, which extends automatically forward and outward when semen is squeezed into the inner catheter.
  • Another object of the present invention is to provide an improved artificial insemination device with an inner catheter for animals, characterized in which a positioning stop member is disposed at the rear end of inner catheter to control the distance of its inward extension.
  • a positioning stop member is disposed at the rear end of inner catheter to control the distance of its inward extension.
  • a further object of the present invention is to provide an improved artificial insemination device with an inner catheter for animals, wherein by conveniently advancing the inner catheter inside the cervical tract a proper distance after engaging the nozzle of catheter tube at the first cervical ring, the length of thin flexible tube inside the front end of inner catheter can be effectively shortened. As such, the pressure required from squeezing the semen dispenser to push the thin flexible tube forward and outward is also reduced, which facilitates the movement of thin flexible tube in the cervical tract and renders the whole process simpler, thereby improving the efficiency of artificial insemination.
  • Yet another object of the present invention is to provide an improved artificial insemination device with an inner catheter for animals, wherein by setting the length of said inner catheter to allow it and the thin flexible tube at its front to conveniently and smoothly advance inside the cervical tract of animal without resistance, semen can be swiftly and accurately delivered to uterus.
  • semen used for artificial insemination does not require massive dilution, while only more concentrated semen in small amount needs to be injected into the inner catheter.
  • the present invention not only offers the economic benefit of saving the semen used, the fertilization rate and the number of fetus are also expected to increase.
  • Yet another object of the present invention is to provide an improved artificial insemination device with an inner catheter for animals, wherein the second nozzle disposed at the front end of inner catheter is an assembly of two rubber sheaths having proper rigidity and elasticity that will not bend or deform after it enters the cervical tract, and the thin flexible tube immobilized therein is not prone to perforation.
  • the forward and outward extension movement of the thin flexible tube is made smoother and more accurate, rendering the practice of artificial insemination more efficient.
  • the improved artificial insemination device with an inner catheter for animals features an inner catheter movably disposed inside a catheter tube 10 of the artificial insemination device with a thin flexible tube 81 and a positioning stop member 82 configured at its front and rear ends respectively.
  • the thin flexible tube 81 is mounted at the front end of inner catheter through a second nozzle 80; the second nozzle is an assembly of a first sheath body 801 and a second sheath body 802 made of material with proper rigidity and elasticity. That is, one end of the first sheath body 801 is securely mounted to the front end of inner catheter 70, while its other end is arranged with an insertion member 8011 of smaller diameter.
  • the outer end of insertion member 8011 is provided with a chamfer R, while its center is disposed with a through guide hole K; the diameter of the thin flexible tube 81 is smaller than the lumen 701 of inner catheter 70 where its open front end 811 is inserted inversely into inner catheter 70 through the guide hole K of first sheath body 801 and extends inwardly to the lumen 701 of inner catheter 70, while its rear end inversely envelops the insertion member 8011 of first sheath body 801.
  • the second sheath body 802 is provided with a sheathing member 8021 that engages exactly the insertion member 8011 of first sheath body 802; its inner end is disposed with an enlarging slot member M and its center is arranged with a through guide hole K.
  • the guide hole K of second sheath body 802 secures the rear end 812 of the thin flexible tube 81 exactly and the slot member M at the inner end corresponds exactly to the chamfer R at outer end of insertion member 8011 without contacting each other (FIG. 13), such that the rear end of thin flexible tube 81 that envelops the chamber R of insertion member will not perforate due to friction.
  • the inner catheter 70 may be mounted inside the catheter tube 10 and nozzle 20 in advance as in prior art and then have the second nozzle 80 and the thin flexible tube 81 disposed at its front end, or the inner catheter 70 may have the second nozzle 80 and the thin flexible tube 81 disposed at its front end and then have its rear end inserted into the catheter tube 10 from nozzle 20. After the second nozzle 80 is mounted at the front end of inner catheter 70, it may be exposed at the front of nozzle 20 or concealed inside the center hole 201 of nozzle 20.
  • the positioning stop member 82 is directly mounted on the exposed portion of inner catheter 70 at P distance apart from the rear end of catheter tube 10. As such, the distance inner catheter 70 can advance is based on the set distance of P.
  • the positioning stop member 82 may be a clipping fastening, or sheathing means so long as it can be securely mounted on inner catheter 70 (the example cited below is a connector 50 for the insertion of insertion tube 31 of semen bottle, bag or syringe 30).
  • the rear end of thin flexible tube 81 at the guide hole K of second nozzle 80 and having a guide member W that unfolds in an inside-out manner forms an accommodation space T.
  • the accommodation space T communicates directly with the lumen 701 of inner catheter 70, while the guide member W is positioned exactly at where guide hole K of the second sheath body 802 of the second nozzle 80 is located.
  • the operator would use conventional operating procedure when using the present invention for artificial insemination in animals. That is, the nozzle 20 and catheter tube 10 are inserted into the vagina 11 of animal body 1 through guide bush 60, where nozzle 20 is extended approximately to the position of first cervical ring 121 of cervical tract 12. Next, the inner catheter 70 is pushed inward so that it and the second nozzle 80 at its front end extend into cervical tract 12 from nozzle 20; when the inner catheter 70 is pushed inward, it would advance no more than a set distance of P because of the positioning stop member 82 provided at its rear end and the set space of P between the positioning stop member 82 and the rear end of catheter tube 10 (FIG. 8).
  • the second nozzle 80 is exposed outside nozzle 20 at an equidistance of P' and will not reach too far into the uterus of animal as in prior art to traumatize the uterus.
  • the catheter tube 10 and the positioning stop member 82 may be bent upward and secured to the positioning strap 41 of Al Buddy 40 as in prior art, or left unbent and laid directly outside the vaginal orifice 111 of female animal 1.
  • the insertion tube 31 of semen dispenser (bag or syringe) 30 is then inserted into the rear end of inner catheter 70 or connector 50 (connector 50 is used as a positioning stop member 82 in this example) and semen fluid is squeezed in.
  • the second nozzle 80 at the front end of inner catheter 70 is in somewhat closed state.
  • the inversely inserted thin flexible tube 81 is also under the exertion of pressure and automatically pushes forward.
  • the outwardly unfolding guide member W provided at the rear end of thin flexible tube 81 around the guide hole K of second nozzle 80 forms an accommodation space T that communicates with the lumen 701 of inner catheter (FIG. 12 and FIG. 13)
  • semen squeezed into the lumen 701 of inner catheter will directly fill the accommodation space T and exert pressure.
  • the entire thin flexible tube 81 would gradually unfold outwardly from its guide member W and extend forward, and deposit semen into the uterus after it is totally extended. That is, because the thin flexible tube 81 is smaller than the lumen 701 of inner catheter and has a certain length, it advances fast along the cervical tract with practically no friction when it extends gradually from the second nozzle 80 under the pressure of semen. When the thin flexible tube 81 is completely stretched, its open front end 811 will reach the uterus or its vicinity to deposit semen into the uterus, thereby completing the artificial insemination procedure in a highly efficient manner.
  • the thin flexible tube 81 is smaller than the lumen 701 of inner catheter, made of pliable material and is of certain length, and its front end 811 is open when semen is deposited into inner catheter 70. But the semen in the inner catheter 70 will not flow out from the open front end 811, but instead, squeezes and closes the front end 811, and is automatically expelled from the front end 811 when the entire thin flexible tube 81 becomes extended. Also because of the pliable nature of thin flexible tube 81, it will advance in the cervical tract 12 smoothly and swiftly without traumatizing the delicate tissue of cervical tract 12 or the uterus.
  • the outwardly unfolding guide member W provided on the thin flexible tube 81 of inner catheter forms an accommodation space T that communicates with an inner catheter 70
  • semen squeezed into the inner catheter 70 will directly fill the accommodation space T and exert pressure, which pushes the entire thin flexible tube 81 to unfold inside-out quickly and smoothly.
  • minimal squeeze force is required, which renders the whole operation convenient and simple.
  • the inner catheter 70 has smaller diameter than catheter tube 10 and the thin flexible tube 81 therein is even smaller than its lumen 701, the thin flexible tube 81 is able to deliver semen swiftly to uterus after its is fully extended.
  • semen used for artificial insemination does not require massive dilution, while only more concentrated semen in small amount needs to be injected into the inner catheter.
  • the present invention not only offers the economic benefit of saving the semen used, the fertilization rate and the number of fetus are also expected to increase.
  • the second nozzle 80 is smaller than nozzle 20 and may be directly extended into the cervical tract 12 of animal. But because the second nozzle 80 is made of rubber material with proper rigidity and elasticity, there is no concern of it traumatizing cervical tract 12 when it advances in it. More so, confined by the advancing length P of inner catheter 70, second nozzle 80 is not expected to reach into uterus and traumatize it. In addition, because the second nozzle 80 has proper rigidity and elasticity, it will not deform to block the extension of thin flexible tube 71 when it is pushed into cervical tract by inner catheter 70, but instead, enables the thin flexible tube 811 to deliver the semen to the uterus to complete the insemination process in an efficient manner.
