Artificial breeding device for dogs

Abstract

The invention discloses an artificial breeding device for dogs. The artificial breeding device comprises an imitated penis, an expansion ball, a handle, sperm ducts, a spray head, inflation and deflation tubes, valves, a sperm inlet and a check valve. The imitated penis and the handle are integrated, the expansion ball is arranged in the middle of the imitated penis, the sperm ducts are arranged in the imitated penis and the handle, the inflation and deflation tubes are arranged in the imitated penis and the handle from the expansion ball to the tail end of the handle, the valves are arranged at the outer ends of the inflation and deflation tubes, the spray head is arranged at the front lower end of the imitated penis, at the outlet positions of the sperm ducts, and the sperm inlet and the check valve are arranged at the tail end of the handle and the outer ends of the sperm ducts. The artificial breeding device is based on a bionic principle of natural mating of the dogs, the imitated penis is plugged into the vagina of a bitch by means of an inflation method, and a working environment for depositing semen into the uterine cavity by utilizing long time is created for artificial semen deposition. By means of the artificial breeding device, artificial fertilization and pregnancy rate is improved from about 20% in the prior art to higher than 90%, and the artificial breeding rate of the dogs is greatly improved.

Description

technical field [0001] The invention relates to an artificial insemination device, in particular to an artificial insemination device for dogs. Background technique [0002] At present, three methods of surgical insemination, intrauterine insemination and intravaginal insemination are usually used in the breeding and improvement of dogs. The disadvantages of the prior art: the surgical insemination method is not easy to popularize due to the complicated operation. The intrauterine insemination method lacks special insemination equipment, which is difficult and easy to cause bleeding, which is more harmful to the bitch. There are also cases where beginners use insemination equipment to penetrate the vaginal wall to inject semen into the abdominal cavity. The lack of ideal tools for intravaginal insemination cannot make the semen enter the uterus smoothly, resulting in backflow of semen and a decrease in the conception rate. According to domestic and foreign reports, the conc...

Disadvantages in the prior art: Surgical insemination is not easy to popularize due to the complexity of the operation

Compared with the traditional method of artificial insemination, this patent has made great progress, but there are still some problems, such as the combination of the insemination device and the vagina during artificial insemination, which needs to be manually grasped, especially the glass tube is used as the outer catheter. Easier to slip off, thus affecting the fertilization effect
