Artificial insemination transplantation device for reproductive medicine

Abstract

The invention discloses an artificial insemination transplantation device for reproductive medicine, and belongs to the field of the reproductive medicine. The artificial insemination transplantationdevice comprises a sperm storage portion and a force applying portion; the sperm storage portion comprises a sperm storage cylinder, an airbag sleeve is slidably mounted on the outer side of the middle of the sperm storage cylinder, a sperm outlet hole is formed in the middle of the top end of the sperm storage cylinder, and a moving plug is mounted in the sperm storage cylinder; the force applying portion comprises a force applying cylinder, a fixing rod is mounted in the middle of the lower end of the force applying cylinder, a grip rod is mounted on the left side of the lower end of the fixing rod, a rotating rod is connected to the middle of the right end of the fixing rod through a hinge rod, a stop plate is mounted at the bottom end of the force applying cylinder, an air outlet checkvalve is mounted in the middle of the stop plate, a pressing airbag is connected to the bottom end of the stop plate, an air inlet tube is mounted in the middle of the bottom end of the pressing airbag, and an air inlet check valve is mounted in the middle of the air inlet tube. The artificial insemination transplantation device has the advantages that the situation that the sperm storage portioncannot be used when the force applying portion is broken is avoided; through cooperation between the rotating rod and the pressing airbag, a single person can complete air inflation and sperm pushingsimultaneously, so that time and labor are saved, and practicality and reliability are high.

Description

technical field [0001] The invention relates to the field of reproductive medicine, in particular to an artificial insemination transplantation device for reproductive medicine. Background technique [0002] Intrauterine artificial insemination, one of human assisted reproductive technologies, generally requires the use of semen transplantation equipment. When artificial insemination is performed, the transplantation tube is installed on the corresponding syringe, and the negative pressure is generated through the syringe, and the sperm suspension is extracted from the transplantation tube. , and then put the transplant tube into the uterine cavity, push the syringe to inject the sperm suspension in the transplant tube into the uterine cavity, thereby completing artificial insemination. Since the general transplant tube is generally thin, there is a gap between it and the cervix, which may easily lead to semen overflow . [0003] Chinese patent (notification number: CN24384...

Problems solved by technology

[0002] Intrauterine artificial insemination, one of human assisted reproductive technologies, generally requires the use of semen transplantation equipment. When artificial insemination is performed, the transplantation tube is installed on the corresponding syringe, and the negative pressure is generated through the syringe, and the sperm suspension is extracted from the transplantation tube. , and then put the graft tube into the uterine cavity, push the syringe to inject the sperm suspension in the graft tube into the uterine cavity, thereby completing artificial insemination. Since the general graft tube is generally thin, there is a gap between it and the cervix, which may easily lead to semen overflow

[0003] Chinese patent (notification number: CN2438429Y) discloses a double-chamber semen transplanter, which is a round tubular instrument made of medical silica gel, consisting of a pipette and an air branch tube located at the tail of the pipette. The ventilated core chamber extends to the annular airbag chamber at the front of the pipette in the pipette interlayer. The annular airbag formed after the annular airbag chamber is inflated blocks the semen from overflowing. The pipette head is a solid hemisphere with a smooth and round surface. Blunt, to avoid damage to the endometrium, the front of the pipette is equipped with a scale line for the tube, which can improve the pregnancy rate of the intrauterine artificial insemination cycle, but the patent still has the following shortcomings: First, the existence of the bronchial tube increases Second, in the process of actual operation, if a single person operates, it is necessary to inflate the air bag first, and then push the semen, which cannot be done at the same time, unless multiple people can guarantee the inflation and push The semen is carried out at the same time, but it will waste manpower, which will bring certain difficulties to the operator; the third, because the air bag chamber and the pipette are integral, the whole pipette cannot be used when the air bag chamber is damaged. use
