Description

A Injector For Embryo Transplant and Inseminate

The present invention relates to a device used for artificial insemination or fertilization of livestock such as cattle and horses, and more particularly, to a fertilized egg implantation and artificial insemination device for inserting a fertilized egg or semen loaded into straw into a genital organ. .

In order to improve livestock, especially cattle, males can see more offspring by physiological reproduction than females.

In nature, females can only see 6 to 10 offspring during their lifetime, but males can see hundreds of offspring, depending on the number of females.

If the semen is collected and diluted in the natural breeding of male cows, it can make 100-300 straws that store one batch of semen at the time of artificial insemination. It will be modified. `

Artificial insemination, instead of directly mating males and females, thaws the frozen semen stored in the straw and uses it as an injector to inject it into a cow's womb to be fertilized and is currently being practiced in general livestock farms.

In addition to such artificial insemination, fertilized egg transplantation has been carried out as an active technique for artificially increasing female reproductive efficiency.

The fertilized egg transplant,

In the case of cows, one egg ovulates on the 21st day of pregnancy in non-pregnancy. In the case of cows, females who have a particularly large amount of milk or Hanwoo cows select females with excellent meat quality and meat mass, and induce ovulation by hormonal injection to induce ovulation of a large number of eggs at a time. The fertilized egg that comes down to the uterus from the fallopian tube, which is a reproductive organ for pregnancy, is implanted after a certain period (6-9 days) after fertilization. After collection, the condition can be examined under a microscope, and then transferred to another cow's womb for transplantation. Extra fertilized eggs are stored frozen and transplanted when necessary.

Fig. 7 is a use state diagram schematically showing a state in which a conventional injection device is inserted into a bovine genital organ.

As shown in FIG. 7, the bovine genital organ 20 has a cervical canal 22 that is tightly closed except the ovulatory body, which passes from the vagina 21 formed of a large space to the uterus 23, and the inside of the cervical canal 22. The uterus 23 is formed of the uterine body and the uterine angle 24, long oval tubes (not shown) are formed at both ends of the uterine angle, and ovaries (not shown) are formed at the ends of both ovaries.

As described above, injecting semen into the cervix or uterus for artificial insemination to become fertilized eggs, or in performing fertilized egg transplantation in which artificially collected fertilized eggs are implanted into another cow's uterus 23, The genitals are injected using the injection device 10.

The injection mechanism 10 supports the sheath 14 loaded with semen loaded at the end and is inserted to pass through the cervix formed by the zigzag irregularities to reach the uterus. The cervix 22 formed by the unevenness is tightly closed so that a strong force is required to navigate through the place, and thus, it is difficult to insert the injector.

8 is an overall configuration (a) and partially omitted enlarged cross-sectional view (b) of an injector according to the prior art.

Referring to the configuration of the conventional injector 10, as shown in Figure 8, the semen or fertilized egg enters into the loaded straw 500, to the piston 11 and the cylinder 12 for discharging the loaded material The cylinder 12 has a handle portion 12b having a sheath fixing portion for fixing the sheath 14 thereon and a diameter of about 3.5 mm for supporting the sheath 14 externally. The length is about 420 mm long thin long long sheath insert portion 12a, the sheath insert portion 12a is located between the straw 500 and the sheath 14, the uterus when entering the device uterus It is a support for the entrance resistance of the officer.

When the injection device is inserted into the genitals of the livestock, the thin part of the sheath insert is required to be a cervical canal 22, which is tightly closed, and the vagina 21 is formed wide. It doesn't have to be thin.

In addition, the length of the straw 500 loaded with the semen or fertilized egg inserted into the sheath 14 is less than about three-quarters of the total length of the sheath inserting portion 12a, and thus the sheath for inserting the straw 500 into the sheath 14a. The length of the 14 and the length of the sheath inserting portion 12a for inserting the sheath 14 are sufficient to add only a predetermined margin to the length of the straw 500.

Nevertheless, the prior art forms almost all of the thin sheath insert 12a except for the upper handle 12b, which is only a fraction of the total length of the cylinder. From the uterus to the broadly formed vagina 21 connected to the cervical canal 22, the uterus is formed of the sheath insert portion 12a of the tape, that is, the length of the uterus is formed too long compared to the tape, and the uterus is hard to get through. The landscape (22) is the sheath insertion portion 12a whistle when passing through the tunnel, giving the difficulty of the operation of the unfamiliar worker due to this whistle, especially in the non-ovulatory period, most of the period when the cervix 22 is firmly closed There was a problem that suffered even more difficulties.

On the other hand, as the length of the sheath inserting portion 12a is formed unnecessarily long, the length of the sheath of the resin material, which is a transparent material inserted therein, must also be formed unnecessarily long, thereby increasing the cost burden of the expensive sheath and increasing the production cost. Wasted and produced waste in the disposal process has become a problem in terms of environment.

In addition, in the conventional injector 100 to secure the sheath 14 to the injector, as shown in Fig. 5, the sheath fixing portion 12c of the cylinder is formed in an incomplete configuration such as a button type, work There is a problem that the sheath is separated from the cylinder.

On the other hand, in the prior art, since the cylinder through-hole 12d is formed larger than the outer diameter of the piston for inserting the straw when the piston 11 is operated, it is difficult to enter straight, and it is easy to have a slope, so that the inside of the straw 500 There is a problem in that the inserted semen or fertilized egg to be loaded inside the straw to push the straw itself in contact with the straw circumference.

On the other hand, such an injection device has a large difference in the length of the genital organs according to the breed and size of the livestock, and even in the same livestock, the insertion length of the injector at the time of artificial insemination and implantation of fertilized egg is different. Since the technique has a fixed length of the sheath inserting portion and the handle portion, it cannot cope with this, and thus, the work cannot be efficiently performed, and there is a burden of preparing an injection device having a different length according to the specification depending on the application case.

The present invention has been devised to solve the above problems,

An object of the present invention, in the injection device for performing semen injection or fertilized egg implantation for artificial insemination in the genitals of livestock, especially cattle,

The length of the thin sheath insert of the cylinder is formed only by the actual required length to be inserted after the cervix of the livestock, and extends the handle of a relatively thick thickness to the insertion position of the cervical canal instead.

By providing a rigid fastening means to prevent the separation of the sheath to the cylinder, forming a guide portion in the inner through-hole, by separating and coupling the handle portion and the sheath inserting portion, and also to form the handle portion by combining several assembly nodes,

The thick tube of the extended handle portion is inserted into the vagina, which is the entrance to the cervical canal, to hold the sheath insertion portion formed in a relatively short length.

When the piston is operating, the piston enters the inside of the straw accurately, and the length of the device can be adjusted according to the application.

Whistling is minimized when passing through the cervical canal and inserting the sheath, and the sheath is firmly tightened to prevent the detachment while significantly shortening the length of the disposable sheath and precisely injecting the straw contents. To adjust the length according to the application,

The present invention provides an implantation apparatus for fertilized egg implantation and artificial insemination, which enables the fertilization and fertilization of the fertilized egg to be remarkably easy and efficient, reduces material costs for the sheath, and minimizes environmental pollution.
