Description

Disposable insemination device for horse artificial insemination

Technical Field

The utility model relates to a disposable insemination device for horse artificial insemination, which belongs to the technical field of animal artificial insemination.

Background

In the beginning of the 20 th century, the effort of the russian Ilya Ivanov brought the artificial insemination technology into practical use, and made a significant contribution especially in the artificial insemination of horses. The artificial insemination technology plays a revolutionary role in breeding high-level sports horses such as Hannover and the like. Taking the German Hannover as an example, before the second war, the Hannover horse is mainly used as a tractor horse and a military horse in agricultural production, other pedigrees are introduced after the second war to be improved into a sport horse, and the artificial insemination technology plays a great role in the process. 2005 data of Association of Australian Horse Breeders showed that 70% of the mares in Austria were bred using artificial insemination. French National Studs 2006 showed that 58% of the breeding of France sport horses were using artificial insemination techniques. Therefore, the artificial insemination technology is widely applied to the breeding of foreign sports horses in the pure green field of the fire. In the process of artificial insemination, how to ensure the comfort of horses, prevent semen from flowing backwards and ensure the sanitation of insemination devices to prevent horse infection becomes the key point of attention of people at present.

The utility model has the advantages that: the spermatic device comprises a spermatic pipe, a spermatic pipe main port and a spermatic hole which are arranged at the two ends of the spermatic pipe; the main mouth end of the vas deferens is also provided with a vas deferens auxiliary mouth and an auxiliary mouth sealing cover, and the auxiliary mouth is used for injecting physiological saline and the like to push semen to be completely injected into the horse body. The outer side of the semen deposition hole end is provided with a wave-shaped silica gel bag, and the inner side is provided with a non-return structure; the wave-shaped silica gel sac adopts a structure with a spherical head, a middle concave ring and a tail expansion area, the spherical head and the middle concave ring are inserted into the horse body, and the tail expansion area is left outside the horse body, so that the comfort level of the horse is ensured, the phenomenon that the horse is injured by the complete insertion of the vas deferens is avoided, and the horse is convenient to pull out. The non-return structure adopts the matching of the central hole of the wall ring in the middle of the vas deferens wall ring and the valve bulge on the non-return valve, thus preventing the semen from flowing backwards due to the pressure generated after the uterus of the horse contracts. The inseminating syringe is disposable, and can ensure sanitation and avoid infection.

In the figure: 1. vas deferens 2, a vas deferens main port 3, a vas deferens auxiliary port 4, an auxiliary port sealing cover 5, a vas deferens hole 6, a spherical head 7, a middle concave ring 8, a tail expansion area 9, a vas deferens wall ring 10, a wall ring central hole 11, a check valve 12, a valve hole 13 and a valve convex block.

Detailed Description

Fig. 1 to 3 show a disposable insemination device for horse artificial insemination, which comprises a vas deferens 1, one end of the vas deferens 1 is a vas deferens main mouth 2, and the other end of the vas deferens 1 is a vas deferens hole 5; a vas deferens auxiliary port 3 is also arranged on the vas deferens 1 at one end of the vas deferens main port 2, and an auxiliary port sealing cover 4 is arranged on the vas deferens auxiliary port 3; the wave-shaped silica gel sac is arranged on the outer side of the seminiferous duct 1 at one end of the seminiferous orifice 5, and the non-return structure is arranged in the seminiferous duct 1; the wave-shaped silica gel capsule adopts a structure of a spherical head 6, a middle concave ring 7 and a tail expansion area 8, the non-return structure adopts the structure that a vas deferens wall ring 9 is arranged on a vas deferens 1, a wall ring central hole 10 is arranged in the middle of the vas deferens wall ring 9, a non-return valve 11 is arranged on one side of the vas deferens wall ring 9 close to the vas deferens 5, and a valve lug 13 and a valve hole 12 are arranged on the non-return valve 11.
