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.
