In prior art, progestational llormones can be utilized to suppress ewe to oestrus and to ovulate, realize the adjustment in estrus cycle, described ewe progestational llormones is a kind of vagina progesterone delayed release device, is made up of the intravaginal suppository of the full sponge cylindrical shape of carrying full medicine.But the feature of oestrusing of dog and sheep is different, and dog has secretions constantly to discharge in during oestrus intravaginal, if therefore birth control device outside ewe palace is applied directly on dog, the secretions silt resistance of dog during oestrus will certainly be caused to discharge, cause inflammation of uterus.If directly draw out a vertical aperture to ensure the words that secretions is discharged smoothly by the middle of sponge, its middle spongy embolus with vertical aperture is after entering vagina, owing to being subject to vaginal wall ground squeezing action, device is out of shape, can block aperture, the sponge leaving aperture simultaneously also easily comes off because quality is too soft.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, birth control device and method of birth control thereof outside the palace providing a kind of applicable dog, with provide a kind of use simple to operate, to contraception device and method of birth control thereof outside small, the cheap dog palace of dog injury.
The present invention is achieved by the following technical solutions:
The invention provides birth control device outside a kind of dog palace, comprise drug delivery layer (1) and supporting layer (2), described drug delivery layer (1) is for being loaded with the cylindric sponge vaginal suppository of the progestogens medicine suppressing bitch to be oestrused, described supporting layer (2) is located in the through hole of the cylindrical shape of drug delivery layer (1), for match with the through hole of drug delivery layer (1) one in siphunculus body.
The medicine sustained-release suppository that described drug delivery layer (1) is is carrier with full sponge.
Described supporting layer (2) is made up of silica gel material; Silica gel material has certain hardness, can ensure that aperture can not be out of shape blocking when dog vagina contraction, and the surface texturisation of silica gel material is general comparatively coarse, and forms certain frictional force between sponge, and bi-material can not be separated.
The progestogens medicine that described suppression bitch is oestrused is progesterone.
The length of described birth control device is 1 ~ 5cm, and diameter is 0.5 ~ 3cm, according to the size design different size using kind of dog.
Present invention also offers a kind of method utilizing birth control device birth control outside above-mentioned dog palace, step comprises: enter early stage in oestrus at discovery bitch, select and the sizeable described birth control device of bitch vagina, by the full disinfectant solution of described birth control device leaching, then send into from bitch vaginal orifice, be pushed into vagina front end, to reach the object of birth control, can take out in bitch later stage of oestrusing, to keep the reproductive performance of bitch.
Described disinfectant solution is bromo geramine.
Principle of the present invention is: dog had two mating periods in 1 year, and each mating period only once oestruses, and generally the estrus cycle of dog is divided into the fourth phase, i.e. proestrum, oestrus, the later stage of oestrusing, anestrus; There is edema in proestrum bitch vaginal orifice, vagina stream haemorrhagic exudates, occurs pheromone in urethra and vaginal secretions during this, can stimulate the generation excitement of public dog, but now bitch refusal and public dog copulation; The progestogens medicine contained in spongy embolus in birth control device of the present invention can suppress bitch to be oestrused during this period; Oestrus, bitch started to be ready to accept copulation, public dog with the barrier effect due to device during bitch copulation, the penis of public dog can not enter bitch vagina completely, thus plays certain inhibition to the ejaculation behavior of public dog; Even if there is a small amount of seminal fluid to enter bitch vagina, the disinfectant solution on device also can have killing action to sperm; Below what time complement each other, jointly ensured the unsuccessful of copulation, thus reach the object of bitch birth control.
