Embodiment 1

[0039] Physical photos of the device of the present invention are as figure 1 ,:

[0040] The device is composed of an arc and two long arms. The inside is a medical nylon bracket, and the outside is a slow-release material mixed with estrogen, progesterone and antibacterial peptide.

[0041] 1. For the shape and size of the internal bracket, see figure 2 , the bracket includes an arc-shaped connecting portion 1 and two long arms 2 .

[0042] (1) The long arm of the bracket: it consists of a cuboid and its rounded top. Wherein the size of the cuboid is large at the top and small at the bottom, the top is 0.40cm long and 0.40cm wide, and the bottom is 0.30cm long and 0.20cm wide. The medial and lateral dimensions of the arm length are different, L1 = 4.00 cm, and L2 = 3.50 cm, respectively. The angle α between the two arms is 95°, the two arms are connected by an arc ring, and the diameter of the ring is 0.25 mm.

[0043] (2) Bracket arc: the arc is 265°, the outer radius r...

Abstract

The invention provides a device for controlling animal follicle development and preventing and treating reproductive tract inflammation and a preparation method thereof. The device is internally provided with a nylon support, and a sustained-release material layer with estrogen, progestational hormones and antibacterial peptide is wrapped around the outer part of the support. The device is provided with a connecting part and two long arms, the bottom ends of the two long arms are connected to the connecting part, a certain included angle is formed between the two long arms, and the portions, at the long arms, of the sustained-release material layer protrude to form a plurality of sheet structures which are orderly arranged. According to the device and the preparation method thereof, medicines and silicone rubber raw materials are mixed according to a certain ratio, and after low-temperature vulcanization forming is carried out, the medicines combined with silicone rubber and a high polymer material support are prepared into a special vaginal embedding bolt; the medicines combined with the silicone rubber can be slowly released for a long time (10 days or more), so that the effectsof effectively controlling the animal follicle development and preventing and treating the vagina and uterine inflammation can be achieved; the adopted materials are non-toxic, harmless and smooth andsoft in texture and have a good compatibility with animal tissues; and the pick-and-place operation of the device is simple.

Description

technical field [0001] The invention belongs to the animal breeding field of animal husbandry and veterinary medicine, and aims to provide a vaginal implant device for controlling animal follicle development and preventing reproductive tract inflammation and a preparation method thereof. Background technique [0002] my country is a big country that raises sheep, pigs and deer. At present, the total number of sheep and goats is close to 400 million, the number of pigs is 480 million, and the number of deer is more than 600,000. With the adjustment of industrial structure and the improvement of environmental protection requirements, intensive and large-scale breeding of fine breeds has gradually become the mainstream. Correspondingly, the demand for reproductive control technology and obstetric disease prevention and control has increased rapidly. For example, the simultaneous estrus, ovulation regulation and timed artificial insemination technology of ewes and sows can red...
