Description

Technical Field

[0001] The invention relates to animal husbandry equipment, in particular to a device for extracting bovine reproductive tract mucus. Background Art

[0002] Accurate estrus identification is one of the key factors to improve the estrus disclosure rate and estrus conception rate of dairy cows. Artificial observation of estrus is one of the main methods for estrus identification of dairy cows, and observation of genital tract mucus is the focus of artificial observation of estrus. The resistance value of mucus can be used to predict the stage of the estrus cycle of dairy cows, thereby predicting the time of artificial insemination. Studies have found that the resistance value of mucus is negatively correlated with follicular development, and the resistance value is lowest 24 hours before ovulation. However, genital tract mucus is generally automatically retained outside the body during the peak of estrus, and it is not easy to observe at other times. Therefore, in order to accurately evaluate the estrus cycle and artificial insemination time, we need a dedicated mucus suction device to extract mucus for analysis. Vaginal mucus is generally thinner, while cervical mucus is more viscous. Therefore, vaginal mucus can be extracted using the piston method, while cervical mucus needs to be extracted by pulling or pushing. However, there are almost no mucus extraction devices for cattle at present, and the few that are available cannot extract vaginal and uterine horn mucus at the same time. Summary of the invention

[0003] 1. Technical issues to be resolved

[0004] A bovine reproductive tract mucus extraction device can extract mucus from the vagina and uterus of the bovine, and can extract mucus from the vagina and uterus of the bovine at the same time.

[0005] (II) Technical solution

[0006] In order to solve the above technical problems, the present invention proposes a bovine reproductive tract mucus extraction device, comprising a first tube body, a second tube body and a push rod, wherein one end of the first tube body is closed, the other end of the first tube body is open, and the closed end of the first tube body is provided with a first through hole;

[0007] One end of the second tube body is closed, and the other end of the second tube body is open. The closed end of the second tube body is provided with a second through hole. The closed end of the second tube body is movably inserted in the first tube body, and the push rod is movably inserted in the second tube body.

[0008] Further improved, there are multiple first through holes, each of which is evenly distributed on the first tube body, the number of the second through holes is the same as the number of the first through holes, and when the second tube body is rotated a certain angle relative to the first tube body, the positions of the second through holes on the second tube body are opposite to the first through holes.

[0009] Further improved, the first tube body is a transparent tube, a first positioning line is provided along the axis of the first tube body, a second positioning line corresponding to the first positioning line is provided along the axis of the second tube body, and when the first positioning line and the second positioning line correspond to each other on a straight line, the second through hole is opposite to the first through hole.

[0010] As a further improvement, a pushing recessed portion adapted to fit a finger is provided at the opening end of the first tube.

[0011] As a further improvement, a first sealing ring is sleeved on the second tube body.

[0012] As a further improvement, a first annular groove is provided along the circumference of the inner wall of the first tube body, the first sealing ring is movably clamped in the first annular groove, and when the second tube body moves in the axial direction relative to the first tube body, the first sealing ring has an interference fit with the inner wall of the first tube body.

[0013] As a further improvement, a second annular groove is provided along the circumference of the outer wall of the second tube body, and the first sealing ring is clamped in the second annular groove.

[0014] As a further improvement, there is an interference fit between the first sealing ring and the first tube body.

[0015] As a further improvement, a second sealing ring is provided between the push rod and the second tube body, and the second sealing ring is sleeved on the push rod.

[0016] As a further improvement, the opening at one end of the first tube body is a trumpet-shaped opening, and a handle is provided at the end of the push rod located outside.

[0017] (III) Beneficial effects

[0018] The mucus in the present invention is divided into vaginal mucus and cervical mucus. When extracting vaginal mucus, the first tube body of the bovine reproductive tract mucus extraction device is first pushed into the vagina, the first through hole and the second through hole are aligned, and the push rod on the second tube body is pulled. Since vaginal mucus is thin, it is easier to obtain. Vaginal mucus enters the second tube body through the first through hole and the second through hole in turn.

[0019] When the first tube body of the bovine reproductive tract mucus extraction device is further pushed inward to the cervix, the second tube body is rotated so that the first through hole and the second through hole are not opposite to each other. At this time, a relatively closed environment is formed in the second tube body. The second tube body is then pushed outward by the thumb, and the relatively viscous cervical mucus is sucked into the first tube body from the first through hole through a greater suction force.

[0020] Finally, the first tube is taken out to collect the cervical mucus, and the push rod is removed to collect the vaginal mucus in the second tube. In this way, the vaginal mucus and cervical mucus of the cow are extracted at the same time, and the estrus of the cow can be identified by the mixed mucus. The structure is simple and the operation is convenient. BRIEF DESCRIPTION OF THE DRAWINGS

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] Please refer to Figure 1 to Figure 2A bovine reproductive tract mucus extraction device comprises a first tube body 1, a second tube body 2 and a push rod 3, one end of the first tube body 1 is closed, the other end of the first tube body 1 is open, and the closed end of the first tube body 1 is provided with a first through hole 4;

[0028] One end of the second tube body 2 is closed, and the other end of the second tube body 2 is open. The closed end of the second tube body 2 is provided with a second through hole 5. The closed end of the second tube body 2 is movably inserted in the first tube body 1, and the push rod 3 is movably inserted in the second tube body 2. The first tube body 1 is made of non-metallic material, such as plastic. The second tube body 2 and the push rod 3 are made of metal, and the push rod 3 can be solid or hollow.

[0029] In this embodiment, there are multiple first through holes 4, each of which is evenly distributed on the first tube body 1, and the number of second through holes 5 is the same as the number of first through holes 4. When the second tube body 2 rotates a certain angle relative to the first tube body 1, the positions of the second through holes 5 on the second tube body 2 are opposite to the first through holes 4. By providing multiple first through holes 4 and multiple second through holes 5, it is more convenient to extract vaginal mucus and cervical mucus. When the first through holes 4 and the second through holes 5 correspond to each other, it is convenient to allow vaginal mucus to enter the second tube body 2. When extracting cervical mucus, the first through holes 4 and the second through holes 5 do not need to be aligned.

[0030] In the scheme of the present invention, when extracting mucus, the first tube body is first pushed into the vagina, the first through hole and the second through hole are aligned, and the push rod in the second tube body is pulled to allow the mucus to enter the second tube body through the first through hole and the second through hole in turn, and the vaginal mucus is collected; the first tube body is further pushed inward into the cervix, the second tube body is rotated, the first through hole and the second through hole are staggered, and the second tube body is pushed and pulled outward by the thumb, and the mucus is sucked into the first tube body from the first through hole, and the cervical mucus is collected.

[0031] In this embodiment, the first tube body 1 is a transparent tube, and a first positioning line 11 is provided along the axial direction of the first tube body 1, and a second positioning line 21 corresponding to the first positioning line 11 is provided along the axial direction of the second tube body 2, and when the first positioning line 11 and the second positioning line 21 correspond to each other on a straight line, the second through hole 5 is opposite to the first through hole 4. By referring to the first positioning line 11 and the second positioning line 21, it can be seen whether the first through hole 4 and the second through hole 5 overlap. The preferred solution is that when the first positioning line 11 and the second positioning line 21 overlap, the first through hole 4 and the second through hole 5 also overlap, and the correspondence between the first positioning line 11 and the second positioning line 21 can be observed through the transparent tube.

[0032] In this embodiment, a push recess 12 adapted to a finger is provided at the open end of the first tube body 1. When pushing or pulling the first tube body 2 and the push rod 3, a finger is used to press the push recess 12 to keep the first tube body 1 stationary, so that the second tube body 2 and the push rod 3 can be rotated or pushed or pulled.

[0033] In this embodiment, a first sealing ring 22 is sleeved on the second tube body 2, and the first sealing ring 22 can seal the open end of the first tube body 1. When the second tube body 2 is pulled, negative pressure can be generated inside the first tube body 1, allowing vaginal mucus to enter the first tube body 1.

[0034] In this embodiment, a first annular groove 13 is provided along the circumference of the inner wall of the first tube body 1, and the first sealing ring 22 is movably clamped in the first annular groove 13. The first sealing ring 22 is fixedly sleeved on the second tube body 2, and the first sealing ring 22 moves following the pulling of the second tube body 2. When the second tube body 2 is rotated, the first sealing ring 22 is located in the first annular groove 13, and when the second tube body 2 moves in the axial direction relative to the first tube body 1, the first sealing ring 22 has an interference fit with the inner wall of the first tube body 1. The interference fit makes the sealing between the first sealing ring 22 and the first tube body 1 better. Through the limitation of the first annular groove 13, the second tube body 2 can have a fixed rotation range, which is convenient for the alignment of the first through hole 4 and the second through hole 5. On the other hand, when the device is not used, the first sealing ring 22 is also clamped in the first annular groove 13 for easy storage.

[0035] In this embodiment, a second annular groove 23 is provided along the circumference of the outer wall of the second tube body 2, and the first sealing ring 22 is clamped in the second annular groove 23. The second annular groove 23 is used to fix the first sealing ring 22 so that the first sealing ring 22 can be fixedly sleeved on the second tube body 2.

[0036] In this embodiment, a second sealing ring 31 is provided between the push rod 3 and the second tube body 2, and the second sealing ring 31 is sleeved on the push rod 3. The function of the second sealing ring 31 is similar to that of the first sealing ring 22, both of which are to improve the sealing performance, but the parts used are different. When the first sealing ring 22 and the second sealing ring 31 are not provided, it is necessary to make the outer diameter of the second tube body 2 close to the inner diameter of the first tube body 1, and the outer diameter of the push rod 3 close to the inner diameter of the second tube body 2, so that the function of sucking mucus can also be achieved, but it is more laborious to suck in this way.

[0037] In this embodiment, the opening at one end of the first tube body 1 is a trumpet-shaped opening 14, and a handle 32 is provided at the end of the push rod 3 located outside. The trumpet-shaped opening 14 facilitates operations such as pulling the second tube body 2 and the push rod 3. The handle 32 is spherical, and it is more convenient to pull the push rod 3 through the handle 32.

[0038] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
