Device for examining size of cervical opening

Abstract

The invention discloses a device for examining the size of a cervical opening, which comprises a hose speculum, wherein an annular mounting ring groove is arranged on the outer round surface of a probe of the hose speculum, a rubber tube is sheathed outside the probe, an annular locating boss is arranged on the inner wall of the front end part of the rubber tube, and the locating boss is clamped in the mounting ring groove on the probe. In the invention, the traditional hose speculum and the rubber tube are skillfully combined, the cervical opening size, the amniotic condition and the fetal presentation height of a pregnant woman can be accurately and quantitively examined, the pain feeling and the uncomfortable feeling of the patient are small, the pain of the patient is greatly reduced, and infection is avoided. Meanwhile, the examining device is simple and convenient to use and has strong operability. The device not only can be used by obstetricians receiving professional training, but also can be operated by the pregnant woman or other people who are given simple introduction. The work intensity of the obstetricians is greatly reduced, the tension of the patient can be effectively released, and problems in the field of cervical opening examination are successfully solved. The device is suitable for large-scale popularization and application.

Description

technical field [0001] The invention relates to a medical detection device, in particular to a detection device for dilation of the cervix used in obstetrics and gynecology. Background technique [0002] As we all know, increasing the rate of vaginal delivery, curbing cesarean section and reducing maternal death caused by postpartum hemorrhage and infection are the focus of attention at home and abroad. Evaluation of the soft birth canal before labor and anal and vaginal examination after labor are essential methods to understand the condition of the cervix, whether the membranes are ruptured, the size of the pelvic cavity, determine the position of the fetus and the degree of descent of the fetal head, determine whether vaginal delivery is possible, and observe the labor process. A woman's vagina is usually closed and connected to the uterus. The cervix of pregnant women should be opened before giving birth. Only when the opening of the cervix reaches a certain level can t...

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.
