Abstract

The utility model relates to a cow sperm delivery device, which is composed of a push rod, an inner sleeve, and an outer sleeve. The push rod is inserted into the inner sleeve, the inner sleeve is inserted into the outer sleeve, the front end of the outer sleeve is enclosed, a sperm outlet hole is arranged at the side of front end, and an inner hole with trapezoid cross section is arranged in the outer sleeve; the length design of the cow sperm delivery device is 40 cm to 50 cm. The opening of the outer pipe for cow sperm delivery device is position aside, during delivering the sperm to the cow, the mucus in the gonopore is uneasy to enter the sperm delivery device and cause the sperm delivery pipe being plugged, no back flow of the sperm occurs, thus the pregnant rate of the cow is effectively improved.

Description

Cattle is used seme-deposition device

One, technical field:

The utility model relates to the instrument of semen deposition, specifically is that a kind of cattle is used seme-deposition device.

Two, background technology: the seme-deposition device that uses is made up of push rod, inner sleeve, trocar sheath at present, push rod is inserted in the inner sleeve, and then with in the two insertion trocar sheath, the front end of inner sleeve is open, and there is smart hole at the front end center of trocar sheath, during use, the deferent duct that seminal fluid is housed is inserted in the push rod front end, then push rod and inner sleeve are inserted trocar sheath jointly, push rod is pushed away forward, the seminal fluid in the deferent duct promptly is output from the smart hole of going out of trocar sheath front end.The artificial insemination's of cattle Best Times is that carry out 3-8 hour after cattle oestruses end, and the interior mucus of cow reproductive tract this moment presents thick, at present used seme-deposition device go out the dead ahead of smart hole at seme-deposition device, during use, cow genitals mucus opening part very easily in the past enters the seme-deposition device tube chamber, seme-deposition device is blocked, caused the cattle seminal fluid not release, the refluence phenomenon of seminal fluid takes place.

Three, summary of the invention:

The purpose of this utility model provides a kind of cattle and uses seme-deposition device, and the heavy-gravity mucus of reproductive tract enters the seminal fluid backward flow problem that in the seme-deposition device seme-deposition device line clogging is caused when using this cattle to solve to the cow semen deposition with seme-deposition device, improves the breeding conception rate of cow.

The technical scheme that its technical problem that solves this utility model adopts is: this cattle is made up of push rod, inner sleeve, trocar sheath with seme-deposition device, push rod inserts inner sleeve, inner sleeve inserts trocar sheath, the front end of trocar sheath seals, there is smart hole the side of front end, has the cross section to be trapezoid endoporus in the pipe.

The Design of length of seme-deposition device is 40CM-50CM in the such scheme.

Beneficial effect:

1, the telescopic opening in this utility model China and foreign countries is at side, and when giving the cow semen deposition, the heavy-gravity mucus of reproductive tract is difficult for entering in the seme-deposition device the semen deposition line clogging, and seminal fluid refluence phenomenon can not take place, and can improve the breeding conception rate of cow effectively.

2, this cattle is 40CM-50CM with the Design of length of seme-deposition device, can carry out the semen deposition of cow cornua uteri, low or when using the semen deposition of the seminal fluid of control property at present at the frozen semen motility rate, seminal fluid directly can be injected in the cornua uteri of cow in estrus, do not make the not high problem of conception rate to solve owing to sperm quantity reaches a certain physical constants, can improve the utilization rate of seminal fluid thus.

Fig. 4 is the telescopic structural representations in this utility model China and foreign countries.

1 push rod, 2 inner sleeves, 3 trocar sheaths, 4 go out smart hole, 5 endoporus

Five, the specific embodiment:

As shown in Figure 1, this cattle is made up of push rod 1, inner sleeve 2, trocar sheath 3 with seme-deposition device, push rod 1 is inserted in the inner sleeve 2, push rod 1 and inner sleeve 2 common insertions in the trocar sheath 3, as shown in Figure 4, the front end of trocar sheath 3 seals, and the front end both sides respectively have one to go out smart hole 4, and the position that the interior correspondence of pipe goes out smart hole 4 has the cross section to be trapezoid endoporus 5; This cattle is 40CM-50CM with the Design of length of seme-deposition device, longer than existing seme-deposition device, best length is 50CM, seminal fluid directly can be injected in the cornua uteri of cow in estrus, do not make the not high problem of conception rate to solve owing to sperm quantity reaches a certain physical constants, improve the utilization rate of seminal fluid.

Fig. 2 provides the structural representation of push rod in this utility model, and push rod 1 is front fine and rear thick, is with metal.

Fig. 3 provides the structural representation of inner sleeve in this utility model, and inner sleeve 2 is cylindrical body, and front end is open, and inner sleeve 2 is with metal.

When this utility model uses, the deferent duct that seminal fluid is housed is inserted in push rod 1 front end, then push rod 1 and the inner sleeve 2 common trocar sheaths 3 that insert, whole seme-deposition device is inserted the uterus of cow, promote push rod 1 forward, seminal fluid promptly goes out smart hole 4 and is output to the uterus from trocar sheath 3 is lateral, owing to go out 4 designs of smart hole at side, it is interior with the semen deposition line clogging that the heavy-gravity mucus of reproductive tract is difficult for entering seme-deposition device, and seminal fluid refluence phenomenon can not take place.
