Problems solved by technology

[0003] 1. Since the catheter 10 extends behind the vagina 11 of the animal mother, the nozzle 20 at the front end is pushed to the position of the first cervical ring 121 of the cervix 12. However, the first cervical ring 121 and the uterus 13 must be There is still a distance, so although the uterus 13 can introduce semen from the cervix 12 through contraction, the large amount of semen ejected from the nozzle 20 must first accumulate at the position of the first cervical ring 121, and cannot flow in instantly In the case of the uterus 13, the most common phenomenon is that the semen accumulated in the first cervical ring 121 will flow back and flow out from the vulva 111. In this way, not only the uneconomical disadvantage of wasting semen, but also the semen The amount of semen flowing into the uterus13 will be relatively reduced and the chances of successful insemination will be reduced
[0004] 2. As mentioned above, in response to the phenomenon that semen is easy to reflux, usually the industry will dilute the semen used in large quantities (generally 5 milliliters to 50-120 milliliters), and also set the inner diameter of the catheter 10 to be larger, which can Provide and accommodate more semen for insemination, but the large amount of diluted semen will obviously reduce the pregnancy rate and the number of conceptions, and the use of more semen also has the uneconomical disadvantage of direct waste
[0005] 3. As mentioned above, since the semen of the catheter 10 is directly released from the nozzle 20, and when the nozzle 20 extends from the outside of the animal mother 1 to the cervix 12, it is unavoidable that the dirt from the outside or the vagina 11 will be accidentally discharged. In this way, it is very easy to cause the risk of bacterial infection and inflammation in the animal's vagina, cervix, and even the uterus during the process of artificial insemination, and at the same time, it also endangers the biological safety of the uterus. sex
[0006] 4. As mentioned above, in order to improve the success rate and safety of artificial insemination, the operation of artificial insemination procedures for animals usually needs to be performed by professionals (such as veterinarians or professional technicians), and this is not the case for raising many livestock. (Such as raising pigs) For the industry, this is obviously a heavy economic load and even has the disadvantage that manpower cannot fully cooperate
[0007] 5. As mentioned above, when the operator extends the catheter 10, that is, the nozzle 20, into the vagina 11 of the animal mother, that is, the cervix 12, he must hold the rear end of the catheter 10 with one hand, and hold and squeeze it with the other hand. The semen bottle 30 obviously has the disadvantages of troublesome, inconvenient, troublesome and time-consuming inefficiency in operation
[0010] 1. Since the film 410 is inserted through the front opening 421 of the catheter 420 and fixed with the nozzle 440 by the guide edge 412, the nozzle 440 must be added first when the tip 411 is extruded from the inside to the outside by the force of semen extrusion. The channel length B (shown in Figure 6) can enter the animal cervix, so, in order to make the film 410 can enter the animal uterus smoothly, the film 410 must have a longer length, however, the longer the length of the film, then Desire to push it out so that the extruding force exposed to the nozzle must be greater, and this obviously has a relatively troublesome situation; If the bottle or syringe, then in the implementation of more limited disadvantages
[0011] 2. When the guide edge 412 of the film 410 is buckled back and combined with the positioning ring 422 of the conduit 420, the film 410 is tightly bound to the peripheral surface of the front end of the conduit 420 in a tension state of a certain degree of tightness, and the nozzle 440 is connected in a tight shape. The most common occurrence is that the film 410 is stuck and combined on the peripheral surface of the film 410. When the film 410 in tension is pushed by the stuck nozzle 440, it is very easy to push and break at the front edge of the conduit 420. hole situation (c as shown in Figure 6), and then, when the semen is squeezed into the catheter 420, the hole will cause air leakage, and the film 410 will not be able to be squeezed out smoothly and quickly poor artificial insemination efficiency or even failure
[0012] 3. As mentioned in the above item, since the perforation c of the film 410 is completely concealed by the nozzle 440, when the authenticity detection cannot be implemented, there are great variables in the quality of its production. It will also greatly reduce the effect of using
[0013] 4. Since the film 410 is inserted inwardly from the opening 421 of the catheter 420, the inner diameter of the catheter 420 (i.e. the hollow space 424) is set to be relatively large for the smoothness of the insertion operation. However, the larger diameter However, it will directly increase the amount of semen used, which is the same as the conventional wisdom, and obviously cannot achieve the economic benefit of saving semen
[0014] 5. In order to reduce the injury of the animal mother during the artificial insemination procedure, usually the nozzles are all set as soft bodies. During the artificial insemination procedure, due to factors such as improper application of force during operation or animal disturbances, it is easy for those skilled in the art to cause injuries. The front end of the nozzle is squeezed, deformed or bent to block the passage, and this, for the film 410 built in the catheter 420, it is very easy to be unable to smoothly extrude for artificial insemination
[0015] This shows that the above-mentioned existing artificial insemination device for animals obviously still has inconvenience and defects in structure and use, and needs to be further improved urgently.
In order to solve the problems existing in artificial insemination devices for animals, relevant manufacturers have tried their best to find a solution, but no suitable design has been developed for a long time, and there is no suitable structure for general products to solve the above problems. This is obviously a problem that relevant industry players are eager to solve

Abstract

The present invention relates to an artificial micro fertilization device for animals. If an elastic insemination sleeve is gathered in a compressed form between the nozzle channel and the front end of the central hole of the catheter, the rear end of the elastic insemination sleeve is positioned at the front end of the nozzle. constituted. It is characterized in that: the catheter, that is, the nozzle, is inserted into the animal's vagina and the nozzle is positioned behind the first cervical ring, and the semen container is squeezed into the semen from the back end of the catheter, and the stretching part of the soft elastic insemination sleeve will be instantly self-sustaining. The front end of the nozzle extends outwards, and the front end freely extends forward along the cervix to the position of the uterus, and with the contraction of the uterus of the animal, the semen squeezed into the extension part of the insemination sleeve will smoothly enter the uterus or uterus through the preset slit at the front end The two corner channels not only improve the effect of semen counterflow, but also provide the economy of micro-insemination and the efficiency of artificial insemination.
