Abstract
The utility model relates to a veterinary apparatus and provides a semen deposition machine for cattle. The machine is characterized in that the semen deposition machine comprises a pushing rod, an inner sleeve pipe and an outer sleeve pipe, wherein the pushing rod is inserted in the inner sleeve pipe in a matching mode and the inner sleeve pipe is inserted in the outer sleeve pipe in a matching mode. The front end of the outer sleeve pipe is provided with a semen-out hole, and a one-way valve used for preventing liquid from flowing into the inner portion of the semen deposition machine for the cattle is installed inside the semen-out hole. By installation of the one-way valve in the semen-out hole, and because of the one-way valve used for preventing the liquid from flowing back, when the semen deposition machine is in use, grume can be prevented from entering the semen-out hole and the inner portion of the semen deposition machine. During semen deposition, by preventing the semen from flowing back, and the problems in the prior art that the grume can enter the semen-out hole and the inner portion of the semen deposition machine easily and the semen is easy to flow back can be solved.
Description
Technical field
This utility model relates to a kind of veterinary's apparatus, is specifically related to the cattle seme-deposition device.
Background technology
The seme-deposition device that uses at present mainly is comprised of push rod, inner sleeve and trocar sheath, push rod is inserted in inner sleeve, inner sleeve is inserted in trocar sheath, the inner sleeve front end is open, and there is smart hole at trocar sheath front end center, during use, the deferent duct of seminal fluid is housed at 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 deferent duct namely goes out the output of smart hole from the front end of trocar sheath.Artificial insemination's Best Times of cattle is to oestrus cattle to finish to carry out in 3-8 hour afterwards, and this moment cow reproductive tract endocrine mucus, in the process that seme-deposition device pushes forward, mucus easily enters out smart hole and seme-deposition device is inner, after seminal fluid is injected the cow reproductive tract, due to the abdominal pressure effect, the part seminal fluid easily is back in seme-deposition device.
The utility model content
The purpose of this utility model is to provide the cattle seme-deposition device, and with cattle in the solution prior art with seme-deposition device in use, mucus easily enters out smart hole and seme-deposition device is inner, during semen deposition, and the problem that seminal fluid easily refluxes.
The technical solution of the utility model is: the cattle seme-deposition device, comprise push rod, inner sleeve and trocar sheath, described push rod inserting is in described inner sleeve, described inner sleeve inserting is in described trocar sheath, the front end of described trocar sheath is provided with out smart hole, described go out to be provided with in smart hole prevent that liquid from flowing into this cattle with the check valve of seme-deposition device inside.
Preferably, describedly go out the end that described trocar sheath front end is located in smart hole.
preferably, described check valve comprises valve body, valve ball and spring, be provided with shoulder hole in described valve body, described shoulder hole comprises a large diameter hole and small diameter bore that communicates, the external port of described small diameter bore is for going out the essence mouth, the external port of described large diameter hole and described trocar sheath internal communication, the inwall of described large diameter hole is provided with convex shoulder, in the large diameter hole of described valve ball between described small diameter bore and described convex shoulder and this valve ball diameter greater than the aperture of described small diameter bore, described spring is located between described valve ball and described convex shoulder, the two ends of this spring respectively with described valve ball and the top interference fit of described convex shoulder.
This utility model arranges check valve in going out smart hole, existence due to the check valve that prevents liquid return, in use, can prevent that mucus from entering out smart hole and seme-deposition device is inner, during semen deposition, prevent that seminal fluid from refluxing, solved in prior art that mucus easily enters out smart hole and seme-deposition device is inner, the problem that seminal fluid easily refluxes.
Description of drawings
Fig. 1 is the structural representation that in this utility model embodiment, cattle is used seme-deposition device;
Fig. 2 is the structural representation of check valve in this utility model embodiment.
The specific embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail:
The cattle embodiment of seme-deposition device, as shown in Figure 1 and Figure 2, comprise push rod 1, inner sleeve 2 and trocar sheath 3, push rod 1 inserting is in inner sleeve 2, inner sleeve 2 insertings are in trocar sheath 3, the front end end of trocar sheath 3 is provided with out smart hole 4, goes out to be provided with in smart hole 4 to prevent that liquid from flowing into this cattle with the check valve 5 of seme-deposition device inside; Check valve 5 comprises valve body 6, valve ball 7 and spring 8, be provided with shoulder hole in valve body 6, shoulder hole comprises a large diameter hole 9 and small diameter bore 10 that communicates, the external port of small diameter bore 10 is for going out the essence mouth, the external port of large diameter hole 9 and trocar sheath 3 internal communication, the inwall of large diameter hole 9 is provided with convex shoulder 11, in the large diameter hole 9 of valve ball 7 between small diameter bore 10 and convex shoulder 11 and these valve ball 7 diameters greater than the aperture of small diameter bore 10, spring 8 is located between valve ball 7 and convex shoulder 11, the two ends of this spring 8 respectively with valve ball 7 and convex shoulder 11 top interference fits.
In use, the deferent duct that seminal fluid is housed is inserted in push rod 1 front end, and the common trocar sheath 3 that inserts of push rod 1 and inner sleeve 2 then inserts the cow uterus with whole cattle with seme-deposition device, promote forward push rod 1, seminal fluid namely enters the uterus by check valve 5, due to the existence of the check valve 5 that prevents liquid return, can prevent that mucus from entering out smart hole 4 and seme-deposition device is inner, during semen deposition, prevent that seminal fluid from refluxing, be fertilized effective, improved the pregnancy rate of cow.
In other embodiment of the present utility model, different from above-described embodiment is, describedly goes out smart hole and can also be arranged on the sidewall of trocar sheath front end; In other embodiment of the present utility model, different from above-described embodiment is that described check valve also can replace with other Medical check valves on the existing market.
