Description

Technical field [0001] The invention relates to a medical detection equipment, in particular to a detection device for the dilatation size of the cervix used in obstetrics and gynecology specialists. Background technique [0002] As we all know, increasing the rate of vaginal delivery, curbing cesarean section and reducing postpartum hemorrhage and maternal death caused by infection are the focus of attention at home and abroad. Evaluation of the soft birth canal before labor and anal and vaginal examinations after labor are essential methods to understand the condition of the cervix, whether the membrane is broken, the size of the pelvic cavity, determine the position of the fetus and the degree of fetal head decline, determine whether the vaginal delivery is possible and observe the labor process. The female vagina is usually closed, and the vagina is connected to the uterus. The cervix of pregnant women should be opened before giving birth, and only when the cervix has been o...

AI Technical Summary

Problems solved by technology

[0003] 1. Although obstetricians and gynecologists are professionals, the above methods can only roughly know the size of the opening of the cervix of pregnant women, and cannot obtain accurate quantitative results, let alone quantitative analysis;

[0004] 2. Since it is necessary to use a vagina expander to stretch the closed vagina of the pregnant woman to observe the size of the opening of the uterus, this will make the pregnant woman feel uncomfortable and increase the pain of the patient;

[0005] 3. Both vaginal examination and digital anal examination are carried out under direct vision, which can only be felt subjectively and cannot be judged objectively, which is very blind;

[0006] 4. The number of anal examinations for postpartum women increases, the chance of infection increases, which affects wound healing, increases the pain of the patient, and increases the chance of neonatal infection;

[0007] 5. The entire observation process cannot be completed by the pregnant woman herself, but must be completed by another person, and this person can only be a professionally trained obstetrician and gynecologist, which will bring about the following problems: 1. Due to the The number of pregnant women is often limited, which will increase the workload of obstetricians and gynecologists; second, under the current situation, most pregnant women are giving birth for the first time and have no personal experience, which often causes pregnant women to be more nervous.
