Uterus ovary multi-part accurate dosing and artificial insemination device special for cows

Abstract

The invention relates to the field of livestock epidemic prevention, in particular to a uterus ovary multi-part accurate dosing and artificial insemination device special for cows, which comprises anouter catheter, a guide wire sleeve, a guide wire, a power conveying structure, a medicament supply structure, a medicament tube, a spiral extrusion structure and a self-suction blowing head. According to the uterus ovary multi-part accurate dosing and artificial insemination device special for the cows, the guide wire with the memory bending characteristic extends into the tip of the top end of the oviduct of the cows according to the structural characteristic that the oviduct of the cows is bent from the two sides of the uterus to the rear lower side of the uterus in a bilateral symmetry mode. An air blowing cavity structure is designed in the outer catheter, the air blowing cavity structure blows a medicine and seminal fluid to a farther area range in the uterus by rapidly spraying airfrom front end opening, and the treatment range and the pregnancy probability are increased. The operation is simple, convenient and practical.

Description

technical field [0001] The invention relates to the field of livestock epidemic prevention, in particular to a multi-part precision drug delivery and artificial insemination device dedicated to cows and ovaries. Background technique [0002] Dairy cow endometritis is a common and frequently-occurring disease in the dairy farming industry, mostly concentrated within 2 weeks after delivery, and the general incidence rate is 20% to 35%. Cow endometritis is usually mucous or purulent inflammation of uterine mucosa. The toxic substances produced by inflammation can kill sperm and embryos and cause infertility in cows. Cow endometritis has become one of the common causes of infertility in cows. Moreover, cow endometritis usually causes various complications such as ovarian cysts. In my country, dairy cow endometritis-type infertility accounts for more than 17% of adult cow infertility. Cow endometritis can not only affect the estrus and pregnancy of dairy cows, reduce the milk pro...

AI Technical Summary

Problems solved by technology

[0004] 1. Traditional treatment methods cannot directly reach the patient's part of the cow, and cannot directly act on the lesion, and the drug infusion range is small, so it cannot effectively cover the lesion area. There is a high probability that there will be no drug in some lesion areas. In this case, it is necessary to repeatedly give medicine to the cow's uterus, the treatment efficiency is low, and the operation is cumbersome

[0005] 2. Traditional uterine treatment cannot simultaneously deliver drugs directly to the complications of the ovary. In the follow-up treatment, separate treatment is required, which prolongs the treatment cycle, and cannot increase the drug concentration in local tissues during treatment, and the drug often refluxes, etc. and other loss phenomena, a large amount of liquid medicine cannot be gathered at the lesion site, which affects the therapeutic effect

[0006] 3. During the insertion of the traditional uterine drug delivery device into the cow's vagina, the catheter has no limit and relatively fixed structure relative to the vagina, which often causes the catheter or syringe to be inserted too deeply during drug delivery, causing discomfort to the livestock. And possible slippage phenomenon, leading to the failure of this operation

[0007] 4. When the traditional uterine drug delivery device infuses powdered therapeutic drugs, the powdered drugs may accumulate in the infusion tube due to poor fluidity and cause blockage. Therefore, the delivery of powdered drugs has always been an important part of the drug administration operation An extremely difficult problem, the existing conventional methods have not been able to achieve the desired effect

[0008] 5. Although the existing applicator can be used as an insemination tool for artificial insemination, it cannot evenly mix the internal semen concentration, resulting in some semen being too thick, and the local sperm concentration being too high, resulting in most of the other semen The concentration of middle sperm cannot reach the minimum concentration index, which greatly reduces the probability of conception of cows
