Description

Technical Field

[0001] The utility model relates to the technical field of reproductive medical equipment, in particular to an artificial insemination and transplantation device for reproductive medicine. Background Art

[0002] Artificial insemination refers to an assisted reproductive technology that uses non-sexual intercourse to deliver sperm to the female reproductive tract to achieve the purpose of making a woman pregnant. In artificial insemination, a semen transfer device is generally required. The transfer tube is installed on the corresponding first syringe, and negative pressure is generated by the first syringe. The sperm suspension is extracted from the transfer tube, and then the transfer tube is placed in the uterine cavity. The first syringe is pushed to inject the sperm suspension in the transfer tube into the uterine cavity, thereby completing artificial insemination.

[0003] The existing artificial insemination devices have a single function. After the syringe is pushed to the bottom, it is easy to overflow and backflow, so that the semen cannot be completely discharged, causing waste and affecting the success rate of artificial insemination; the material of the catheter is relatively soft, and it is difficult to pass through the cervical opening into the uterine cavity, and it is not easy to control the depth of entering the uterine cavity. The hard catheter is easy to injure the cervix or uterine cavity tissue during the insemination process; the speed and temperature of the semen injection cannot be accurately controlled and constant. Too fast or too slow injection speed will cause pain to the patient. As the temperature drops (below 37 degrees), it will have a certain impact on the vitality of the sperm.

[0004] Therefore, there is an urgent need for an artificial insemination and transplantation device for reproductive medicine to solve the problems encountered in the above-mentioned lithotomy position treatment. Utility Model Content
