Description

Technical Field

[0001] The utility model relates to the technical field of artificial insemination of sows, in particular to a sperm injector for artificial insemination of pigs. Background Art

[0002] In order to ensure breeding efficiency, artificial insemination using a sperm injector is a common method in pig farm breeding. During the production process of pigs, a large number of bacterial infections often exist in the uterus of sows, which affects the production performance of pigs. However, the cervix of sows only opens during estrus, and remains closed during the daily production process. However, traditional insemination tools have a single function and cannot be used for sampling, which increases the difficulty of differential diagnosis of uterine pathogens in sows. Content of the Utility Model

[0003] In view of the above-mentioned disadvantages of the prior art, the purpose of the present utility model is to provide a sperm injector for artificial insemination of pigs to sample uterine orifice tissue samples while inseminating, which facilitates the differential diagnosis of uterine pathogens in sows.

[0004] A sperm injector for artificial insemination of pigs includes a sperm injection component and an outer layer for packaging the sperm injection component; the sperm injection component includes a catheter and a sperm injection head:

[0005] The sperm injector further includes:

[0006] A sampling cloth fixedly installed on the sperm injection head; and

[0007] A protective layer located inside the outer layer, covering the sperm injection head.

[0008] In one embodiment, the outer layer has a sealed structure and is made of a plastic bag.

[0009] In one embodiment, the sperm injection head is fixedly installed at the corresponding end of the catheter, and the semen channels of the catheter and the sperm injection head are connected.

[0010] Further, the catheter is made of silica gel.

[0011] In one embodiment, the sampling cloth is a flocked cloth, and the flocked cloth is arranged to wrap the outer surface of the sperm injection head.

[0012] In one embodiment, the end of the catheter facing away from the sperm injection head passes through the protective layer, and the protective layer is made of a plastic film.

[0013] Further, in the initial state, the sperm injection head and the sampling cloth are accommodated in the space formed by the protective layer. When the catheter is pushed into the uterus of the pig, the sperm injection head pierces the protective layer.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows: The insemination device has a simple structure and good portability. While meeting the needs of insemination, it also has the function of sampling uterine orifice tissue samples, with good dual functionality, which provides convenience for the differential diagnosis of sow uterine pathogens.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used in the description of the present utility model herein are only for the purpose of describing specific embodiments, and are not intended to limit the present utility model. The term "or / and" used herein includes any and all combinations of one or more of the related listed items.

[0024] Please refer to Figures 1-3 , this embodiment provides an insemination device for artificial insemination of pigs, which includes an insemination component composed of a catheter 2 and an insemination head 3, an outer layer 1 for packaging the insemination component, a sampling cloth 4 fixedly installed on the insemination head 3, and a protective layer 5 located inside the outer layer 1.

[0025] The outer layer 1 has a sealed structure and the outer layer 1 is made of a plastic bag. The insemination head 3 is fixedly installed at the corresponding end of the catheter 2, and the semen channels of the catheter 2 and the insemination head 3 are connected, and the catheter 2 is made of silica gel. The sampling cloth 4 is a flocked cloth, and the flocked cloth is arranged to wrap the outer surface of the insemination head 3. Considering the excellent adsorption performance of the flocked cloth, this embodiment takes the flocked cloth as the sampling cloth 4 as an example for illustration. The tissue sample in the uterus adheres to the sampling cloth 4, so as to achieve the purpose of sampling.

[0026] The protective layer 5 covers the insemination head 3, the end of the catheter 2 facing away from the insemination head 3 passes through the protective layer 5, and the protective layer 5 is made of a plastic film. In this embodiment, based on the structural design that the protective layer 5 covers the insemination head 3 and the sampling cloth 4, before the insemination device is sent to the uterine orifice of the sow, since the sampling cloth 4 is protected by the protective layer 5 and is not interfered by the external environment, therefore, the contamination of other tissue samples is avoided, and accurate sampling at the uterine orifice is achieved.

[0027] In the initial state, the insemination head 3 and the sampling cloth 4 are accommodated in the space formed by the protective layer 5. When the catheter 2 is pushed into the pig's uterus, the insemination head 3 pierces the protective layer 5.

[0028] The insemination device of this embodiment has the following usage process:

[0029] First, remove the outer layer 1,

[0030] Next, place the insemination component with the protective layer 5 against the uterine orifice of the sow;

[0031] Then, push the catheter 2 towards the uterus so that the insemination head 3 breaks through the protective layer 5 to send sperm into the pig's uterus. It should be noted that during the process of the insemination head 3 breaking through the protective layer 5, the tissue sample at the uterine orifice adheres to the sampling cloth 4 to achieve synchronous sampling.

[0032] After insemination, take out the insemination component, cut off the sampling cloth 4 and transfer it to a self-sealing bag filled with physiological saline. After being fully dissolved, pour it into a centrifuge tube for tissue sample detection.

[0033] In summary, compared with the traditional single-function insemination tool, the insemination device of this embodiment has the following advantages: The insemination device of this embodiment has a simple structure and good portability. While meeting the needs of insemination, it also has the function of sampling uterine orifice tissue samples, with good dual functionality, which provides convenience for the differential diagnosis of sow uterine pathogens.

[0034] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0035] The above-described embodiments only represent several implementation manners of the present invention, and the description thereof is relatively specific and detailed. However, it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
