Description

Injector cover of artificial insemination device for livestock {SYRINGE COVER FOR ARTIFICIAL INSEMINATION APPARATUS FOR LIVESTOCK}

The present invention relates to an injector cover of an artificial insemination apparatus for livestock, and more particularly, for livestock, which is not only easy to manufacture but also allows seed seeding liquid to be ejected into the womb of a livestock without being refluxed, thereby improving implantation rate. It relates to an injector cover of an artificial insemination device.

Generally, cattle, horses, deer, and the like have been widely used for artificial fertilization, in which fertilized seeds are freeze-preserved so that fertility can be improved and then fertilized at the appropriate time after fertilization.

As a method of artificial insemination, rectal vaginal injection method, planar injection method and uterine forceps method and the like are known, the artificial insemination apparatus using a syringe-type injector in consideration of these problems is disclosed in Korean Patent Laid-Open Publication No. 1999-048206 (July 5, 1999) is disclosed as a "self-correcting device."

In general, the artificial insemination device for livestock is pressurized by receiving a seed body fluid tube, one end of which is inserted into the vagina of the target animal, and one end of which is housed in the device body and inserted into the womb of the livestock, and the seed crystal solution is received at the insertion end. Thereby comprising a semen injector for ejecting the seed sperm into the uterus and an injector cover coupled to the outside of the semen injector to block the end of the semen injector.

The seed sperm tube generally comprises a tube made of a synthetic resin member and a cotton swab accommodated for ejecting the seed sperm at the same time as the seed sperm is contained in the tube while preventing the bleeding of the seed sperm in the open end. Are kept in.

1 is a cross-sectional view of the injector cover of a conventional artificial insemination device for livestock. As shown, the semen injector 101 is composed of a tubular injection tube 103 formed of a metal member, and a rod-shaped plunger 105 accommodated in a reciprocating manner inside the injection tube 103. The seed sperm tube 111 has a tube 113 containing the seed sperm 115 and a cotton swab 117 housed in contact with the plunger 105 in one end of the tube 113.

On the other hand, the injector cover 120 is formed of a transparent soft synthetic resin member and the tube body 121 is coupled to the outside of the injection tube 103 to accommodate the injection tube 103 of the semen injector 101 therein, It is composed of a nozzle member 131 is coupled to one end of the tube body 121 to prevent the seed crystal solution tube 111 is separated and the seed crystal solution 115 is ejected through the nozzle hole 132a formed along the axis. .

The front end portion of the tube body 121 is formed with a locking portion 123 reduced in the radial direction to prevent the nozzle member 131 from being separated. An injection tube accommodating part 132b and an injection tube accommodating part 132b are accommodated in the nozzle member 131 so as to accommodate the end region of the injection tube 103 of the semen injector 101, and the seed crystal solution is reduced in the radial direction. The tip of the tube 111 is accommodated so that the seed-seated liquid tube accommodation hole 132c, which is held and held, and the fine nozzle hole 132a reduced along the radial direction on one side of the seed-seated liquid tube accommodation hole 132c, respectively. Formed.

However, in the injector cover 120 of the conventional artificial insemination apparatus for livestock, the radial direction at the tip of the tube body 121 in order to prevent the nozzle member 131 accommodated inside the tube body 121 is separated. In order to form a reduced engaging portion 123 along the current, it is currently difficult to manufacture due to technical and cost problems in the domestic situation is mainly dependent on imports. Accordingly, there may be a problem of supply and demand imbalance and relatively high purchase cost.

In addition, the seed crystal solution 115 is ejected through the fine nozzle hole 132a so that the nozzle hole is easily blocked when it comes in contact with the inner wall of the uterus, whereby the seed crystal solution 115 is not injected into the uterus and the nozzle member ( 131) and the tube body 121 has a structural problem that is not flown back to the gap between the body.

2 is a view showing another example of the injector cover of a conventional artificial insemination device for livestock. The same reference numerals are given to the same and the same components as those described above with reference to FIG. 1, and a detailed description thereof will be omitted. As shown, the injector cover 150 is formed of a soft transparent synthetic resin member, a cylindrical tube body 151 into which the semen injector 101 is inserted, and a conical shape coupled to one end of the tube body 151. It is configured to include an injection guide 161.

In one side of the inner side along the longitudinal direction of the injection guide 161, a tube accommodation hole 162a is formed to accommodate one end of the tube body 121 at a predetermined length, and a tube at one side of the tube accommodation hole 162a. The seed sperm tube receiving hole 162b is formed in communication with the receiving hole 162a and reduced along the radial direction to accommodate the seed sperm tube 111.

On one side of the seed crystal tube receiving hole (162b) is formed a fine nozzle hole 162c is reduced in the radial direction and in communication with the seed crystal tube receiving hole (162b). On the outer surface of the injection guide 161, a plurality of spiral ribs 162d extending from the attachment to the tube body 151 side are formed so as to facilitate insertion.

However, in the injector cover 150 of the conventional artificial insemination device for livestock, as in the injector cover 120 described above with respect to FIG. 1, the tip region of the injection guide 161 may contact the inner wall of the uterus. In this case, there is a problem that the fine nozzle hole 162c is easily clogged and the seed crystal solution 115 flows backward to prevent the successful implantation.

Accordingly, it is an object of the present invention to provide an injector cover of an artificial insemination device for livestock, which is not only easy to manufacture but also improves the implantation rate by allowing the seed sperm to be ejected into the uterus of the animal without being refluxed.
