Description

Injection device for artificial insemination {Injection device of frozen semen for artificial insemination}

The present invention relates to an apparatus for injecting fertilizer for artificial insemination, and more particularly, to provide an improved crystallizer injector for easily injecting sperm of a frozen male contractile into the genital organ of a female livestock for fertilization of animals. It is about.

Artificial insemination is to increase fertility rate by injecting male sperm into the genitals so that male sperm can be fertilized artificially without artificial sperm binding to the egg.

The artificial insemination can be modified several times during the estrus of livestock, which can contribute to excellent seed improvement while improving fertilization (conservation) rate, and also can prevent various diseases that can occur during natural mating process. For example, most livestock are in artificial insemination.

Various types of injection devices have been developed and used for injecting male crystallites into the female genitalia for artificial insemination, and the applicant has also devised Utility Model Registration No. 293240.

Looking at the contents of such a pre-registration through Figure 5,

The injection device 1 of the pre-registration includes an injection guide member 5 such as a syringe having a piston 2, a cylinder 3, and an injection hole 4, and the injection hole 4 has a straw tube 6 at the tip. The support member 7 is connected using the coupling member 8.

The coupling member 8 is configured to be coupled to the coupling guide member 10 having an injection tube 9 for receiving the straw tube (6).

In the conventional injection device as described above, the copper crystal in the injection guide member is thrown by inserting the injection tube into the female vagina of the target livestock and then operating the injection guide member coupled to the coupling member having the stove tube coupled with the injection tube. It is discharged through the tube to the entrance of the uterus inside the vagina.

In this conventional technique, since the straw tube discharging the copper crystals is inserted only to the entrance of the uterus, even if the crystallites are supplied to the entrance of the uterus, it is difficult to reach the ovaries through the fallopian tubes.

In the case of the determinant, the survival time is short (about 10 hours), so the conception rate is not high because the life span before reaching the ovary through the fallopian tube having a fairly narrow and long length at the entrance of the uterus.

In other words, when sperm proceeds to the ovary through the fallopian tube at the entrance of the uterus during natural mating, the sperm in the natural state can survive for a considerable time (a few days). There is.

The reason is that the diameter of the straw tube is large and free movement is not possible. Therefore, it is difficult for the straw tube to enter the tubular tube, which is taken like a bow.

Therefore, the present invention is designed to solve the above problems and is configured to be freely movable (bent) while reducing the diameter of the straw tube which is interposed inside the injection tube and injects (supplies) substantially copper crystals. The main purpose is to increase the fertility rate by injecting the crystallites in close proximity to the ovary while having artificial sequestration by providing a separate flow prevention device that can limit the movement of the livestock.
