Artificial trace insemination device for animal

Abstract

The invention relates to artificial microscale semination machine used for animal. A elastic semination sleeve is set between injector passage and front end of conduit central pore in compressed condition, and the back end of said elastic semination sleeve is located on front end of injector. The invention is characterized in that: inserting injector into animal vaginal and making it in the first neck ring of uterine cervix, the extension part of elastic semination sleeve extending from injector front end by using entry pressure of semen from conduit back end, the extension part extending to uterus along uterine cervix, the entered semen entering into uterus or two passage in uterus corner through preset joint-cutting smoothly cooperated with contraction of animal uterus. The adverse current effect of semen is improved, and the economic benefit of micro-scale semination and artificial semination efficiency are increased.

Description

technical field [0001] The present invention relates to an artificial micro-insemination device for animals, in particular to an artificial micro-insemination device which is extremely simple in design, extremely simple and convenient in use, and can enable animal semen to reach the two channels of the uterine horns or the uterus quickly and smoothly, so as to greatly improve The success rate of artificial insemination, and the effective saving of animal semen for artificial insemination, so as to give full play to the spiritual and economic benefits of micro-insemination, and make the implementation of artificial insemination more safe, hygienic and humanized, which is very practical and applicable Sexuality, ideality and progress, and an unprecedented artificial microinsemination device for animals. Background technique [0002] By the way, the traditional artificial insemination device for animals is set up and works, roughly as figure 1 , shown in Fig. 2, it is mainly m...

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 occurrence 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 inflow The semen of uterus 13 will be relatively reduced and the probability 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 a large amount (generally 5cc diluted to 50-120cc), and also set the inner diameter of the catheter 10 to be larger, so as to 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
