Technical Field

The invention relates to animal husbandry equipment, in particular to a cattle genital tract mucus extraction device.

Background

Accurate estrus identification is one of key factors for improving the oestrus uncovering rate and the oestrus conception rate of the dairy cows, artificial observation of estrus is one of the main methods for the oestrus identification of the dairy cows, and observation of mucus in the reproductive tract is the key point for artificial observation of estrus. The resistance value of the mucus can be used for predicting the period of the oestrus cycle of the cow so as to predict the artificial insemination time, and research finds that the resistance value of the mucus is negatively correlated with follicular development and is lowest 24h before ovulation. However, the mucus in the genital tract is generally left outside the body only in the full estrus period, and is not easy to observe in other time. Therefore, in order to accurately evaluate the oestrus cycle and the artificial insemination time, a special mucus suction device is needed to extract mucus for analysis. Vaginal mucus is generally thin and cervical mucus is more viscous, so vaginal mucus can be extracted by a piston method, and cervical mucus is extracted by pulling or pushing with great force. However, there are few available devices for extracting mucus from cattle, and the only devices that do not provide for the simultaneous extraction of mucus from the vagina and uterine horn.

Disclosure of Invention

Technical problem to be solved

A mucus extraction device for cow genital tract can extract mucus in cow vagina and uterus, and can simultaneously extract mucus in cow vagina and uterus.

(II) technical scheme

In order to solve the technical problem, the invention provides a cow genital tract mucus extraction device which comprises 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 provided with an opening, and one closed end of the first tube body is provided with a first through hole;

one end of the second pipe body is closed, the other end of the second pipe body is an opening, a second through hole is formed in the closed end of the second pipe body, the closed end of the second pipe body is movably inserted into the first pipe body, and the push rod is movably inserted into the second pipe body.

In a further improvement, the number of the first through holes is multiple, the first through holes are evenly distributed on the first pipe body, the number of the second through holes is the same as that of the first through holes, and when the second pipe body rotates for a certain angle relative to the first pipe body, the positions of the second through holes distributed on the second pipe body are opposite to the first through holes.

In a further improvement, the first tube body is a transparent tube, a first positioning line is arranged along the axis direction of the first tube body, a second positioning line corresponding to the first positioning line is arranged along the axis of the second tube body, and when the first positioning line and the second positioning line are corresponding to each other on a straight line, the second through hole is opposite to the first through hole.

In a further improvement, a pushing concave part adapted to fingers is arranged at the opening end of the first pipe body.

Further improved, the second pipe body is sleeved with a first sealing ring.

Further improved, be equipped with first annular groove along first body inner wall circumference, first sealing ring activity card is established in first annular groove, and when the second body removed at the axis direction for first body, first sealing ring with first body inner wall interference fit.

Further improved, a second annular groove is formed in the circumferential direction of the outer wall of the second pipe body, and the first sealing ring is clamped in the second annular groove.

In a further improvement, the first sealing ring and the first pipe body are in interference fit.

In a further improvement, a second sealing ring is arranged between the push rod and the second pipe body, and the second sealing ring is sleeved on the push rod.

In a further improvement, the opening at one end of the first pipe body is a horn-shaped opening, and a handle is arranged at one end of the push rod, which is located outside.

(III) advantageous effects

The mucus in the present invention is classified into vaginal mucus and cervical mucus. When the vaginal mucus is extracted, the first tube body of the cow genital tract mucus extraction device is pushed into a vagina, the first through hole and the second through hole are aligned, and the push rod on the second tube body is pulled, so that the vaginal mucus is relatively thin and is relatively easy to obtain. Vaginal mucus enters the second tube body through the first through hole and the second through hole in sequence.

When further inwards propelling movement to the cervix with cow genital tract mucus extraction element's first body, rotate the second body, make first through-hole and second through-hole not relative, form the environment airtight relatively in the second body this moment, rethread thumb promotes the outside pull of second body, and it is internal to follow first through-hole suction first body with comparatively thick and viscous cervix mucus through great suction.

And finally, taking out the first tube body, collecting cervical mucus, taking down the push rod, and collecting vaginal mucus in the second tube body. Therefore, vaginal mucus and cervical mucus of the cattle are extracted simultaneously, and the cattle can be estrualized by mixing the mucus. Simple structure and convenient operation.
