AI Technical Summary
Existing insemination devices are easily affected by high temperatures during transportation and storage, causing premature semen overflow. The low-temperature wax in existing solutions is prone to premature melting and cannot effectively prevent semen overflow.
A low-temperature wax layer and a biological gel layer are filled in the sealing head. When the low-temperature wax layer melts at high temperature, the gel layer flows out under the action of external force, ensuring that semen does not overflow before use. During use, the gel layer opens the channel under the action of the sow's body temperature.
It effectively prevents semen from spilling out during transportation and storage due to premature melting of low-temperature wax, ensuring that semen can smoothly enter the sow's body during fertilization.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of animal insemination devices, in particular to a sow pregnancy insemination device. Background Art
[0002] At present, in order to improve the efficiency of sow pregnancy during sow mating, artificial insemination is generally used, that is, the boar semen collected in advance is sent into the sow's body through an insemination device to achieve the purpose of fertilization.
[0003] Most insemination devices currently on the market generally have a problem, that is, there is a risk of semen overflow during transportation and storage. The root cause is that in order to facilitate the rapid insertion of semen in the insemination device into the sow's body, a barrier layer with low-temperature wax is set at the end of the insemination device, and a disposable safety cap is equipped on the outside. When in use, the safety cap is broken off and the insemination device is inserted into the sow's body. The sow's body temperature is used to melt the low-temperature wax, allowing the semen to flow out smoothly.
[0004] However, during transportation, low-temperature wax is easily affected by the ambient temperature. Once the ambient temperature is slightly higher, the low-temperature wax will melt prematurely, causing the semen in the vas deferens to overflow before it is inserted into the sow's body.
[0005] To solve this problem, our company developed this insemination device. Utility Model Content
[0006] (1) Technical problems solved
[0007] In view of the deficiencies in the prior art, the utility model provides a sow pregnancy insemination device, which solves the problem that the prior insemination device is easily affected by high temperature and causes premature semen overflow.
[0008] (2) Technical solution
[0009] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a sow pregnancy insemination device, comprising a vas deferens, a semen storage bag and a sealing head for sealing semen.
[0010] The vas deferens comprises a filling port with an open top, a rod and an insemination portion. A liquid inlet is provided between the rod and the filling port, and a liquid outlet is provided between the rod and the insemination portion.
[0011] The sperm storage bag comprises an expandable sperm storage chamber in the middle, an anti-dropping clamping head is provided at the head of the sperm storage chamber, and a bionic annular head is provided at the tail of the sperm storage chamber.
[0012] As a further preference, the sealing head includes a sealing plug and a safety cap.

[0014] As a further preference, an anti-slip step is provided at the upper middle portion of the rod.
[0015] (3) Beneficial effects
[0016] The utility model provides a sow pregnancy insemination device, which has the following beneficial effects:
[0017] The sow conception insemination device is improved on the basis of the existing insemination device by adding a filling link inside the sealing head. After the low-temperature wax is filled in the sealing head, a layer of biological gel is filled to completely seal the low-temperature wax in the sealing head. In this way, even if the low-temperature wax is affected by high temperature and melts prematurely, there is still a layer of gel to protect the semen, which can effectively prevent the semen from overflowing prematurely. When in use, the gel layer will flow out under the action of external force, thereby allowing the semen to flow into the sow's body. Therefore, as long as no external force is applied before fertilization, the gel layer will not flow out, thus preventing semen from overflowing. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0024] like Figure 1-4 As shown, the utility model provides a technical solution: a sow pregnancy insemination device, comprising a vas deferens 1, a semen storage bag 2 and a sealing head 3 for sealing semen.
[0025] The vas deferens 1 includes a filling port 12 with an open top (the open structure is convenient for filling), a rod 11 and a sperm deferens 13. The middle and upper part of the rod 11 is provided with an anti-slip step 111, and the anti-slip clamp 22 is sleeved on the anti-slip step 111, thereby preventing the sperm storage bag 2 from falling off (it should be noted that Figure 1 The middle semen storage bag 2 is only a schematic diagram. During the actual filling process, the anti-slip clamp 22 at the head of the semen storage bag 2 must not exceed the anti-slip step 111). A liquid inlet 14 is provided between the rod 11 and the filling port 12, and a liquid outlet 15 is provided between the rod 11 and the semen delivery part 13.
[0026] The semen storage bag 2 (made of silicone) includes an expandable semen storage chamber 21 in the middle. The head of the semen storage chamber 21 is provided with an anti-slip clamp 22, and the tail of the semen storage chamber 21 is provided with a bionic ring head 23. The bionic ring head 23 consists of 6-8 pieces. These 6-8 pieces are roughly divided into three groups. The front group consists of approximately 3-5 pieces, the middle group has 1 piece, and the tail group has 2 pieces. Spaces are reserved between the front, middle and tail (to imitate the length of the sow's birth canal folds, so as to better advance the inseminator).
[0027] The sealing head 3 includes a sealing plug 31 and a safety cap 32 .
[0028] An inlet 311 is provided at one end of the sealing plug 31 away from the safety cap 32, and an injection port 312 is provided at the other end. The injection port 312 is sealed and connected to the safety cap 32. A low-temperature wax layer 313 and a gel layer 314 are respectively provided in the sealing plug 31 (food-grade bio-gel is used, which is non-toxic and harmless and will not affect the sow's birth canal).
[0029] Compared with the traditional sealing head 3, the sealing head 3 in this structure is longer in size. This is to allow the low-temperature wax layer 313 and the gel layer 314 to be filled at the same time. The ratio of the low-temperature wax layer 313 to the gel layer 314 is 5:5 or 6:4, and the ratio of the low-temperature wax layer 313 must not be less than one-half.
[0030] At the same time, the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.
[0031] During use, semen is poured into the semen storage bag 2 through the filling port 12 at the top of the vas deferens 1 and then flows into the semen storage bag 2 through the liquid inlet 14. After the semen is filled, the semen storage bag 2 is in an expanded state, and then the filling port 12 is sealed (tightened with a practical silicone plug).
[0032] During fertilization, the safety cap 32 is first broken off, and then the sealing head 3 is inserted into the sow's reproductive tract. The bionic ring head 23 at the tail of the sperm storage chamber 21 facilitates the advancement of the insemination device as a whole into the sow's body until it reaches the sow's uterus. The low-temperature wax layer 313 is melted by the sow's body temperature. At this time, the sperm storage chamber 21 is connected to the sow's birth canal, and the high pressure inside the sperm storage chamber 21 will be released (because the sperm storage chamber 21 expanded in the early stage and formed pressure). The gel layer 314 inside the sealing plug 31 will be automatically squeezed out under pressure, thereby completely opening the channel of the sealing head 3, and the semen is ejected into the sow's uterus under pressure to complete fertilization.
[0033] It should be particularly noted that when the low-temperature wax layer 313 melts prematurely, the safety cap 32 is broken off and the low-temperature wax layer 313 will gradually flow out from the injection port 312 of the sealing plug 31. At this time, the gel layer 314 inside the sealing plug 31 still remains inside the sealing plug 31. As the pressure inside the semen storage chamber 21 is gradually released, the gel layer 314 will slowly flow out from the injection port 312. This reserves valuable preparation time for the staff. The staff can use the time difference of the slow outflow of the gel layer 314 to quickly insert the insemination device into the sow's body, thereby preventing the semen from overflowing prematurely.
[0034] To sum up, the sow pregnancy insemination device is improved on the basis of the existing insemination device, and a filling link is added inside the sealing head. After the low-temperature wax is filled in the sealing head, a layer of biological gel is filled, so that the low-temperature wax is completely sealed in the sealing head. In this way, even if the low-temperature wax is affected by high temperature and melts prematurely, there is still a layer of gel to protect the semen, which can effectively prevent the semen from overflowing prematurely. When in use, the gel layer will flow out under the action of external force, thereby allowing the semen to flow into the sow's body. Therefore, as long as no external force is applied before fertilization, the gel layer will not flow out, and semen overflow can be prevented.
