Description

Vagina expanding device, placement device of vagina expanding device and use method of vagina expanding device

Technical Field

The invention belongs to the field of medical equipment, and particularly relates to a vagina expanding device, a placement device of the vagina expanding device and a use method of the vagina expanding device.

Background

In order to avoid prolongation of labour and to promote uterine contraction, artificial rupture of membranes and the use of oxytocin in labour are common interventions. The artificial membrane rupture technology is firstly proposed by an obstetrician Thomas Denman in England in the middle of the 18 th century, means that a common medical operation of puncturing, hooking or clamping amnion by using a sharp medical instrument is adopted in a medical intervention mode to enable amniotic fluid to flow out, uterine contraction can be strengthened and the labor process can be accelerated when the labor process is stopped, the amniotic fluid can also be observed to evaluate whether the fetus has oxygen deficiency, and the artificial membrane rupture technology is a medical intervention measure which is often used in the process of vaginal delivery and is widely applied in developing countries. Artificial rupture of membranes can be considered firstly when uterine contraction is lack of strength, the latent period is prolonged, fetal heart monitoring is abnormal, and the like. Manual membrane rupture is usually performed clinically using tissue forceps and needles. Researches show that the incidence of injury of operators, injury of pregnant women and injury of fetuses is greatly reduced by using the tissue forceps to perform the manual membrane rupture, and the success rate of the tissue forceps to perform the manual membrane rupture is higher than that of the needle to perform the manual membrane rupture. Therefore, tissue forceps are often used for manual membrane rupture in clinic.

The artificial membrane rupture method comprises the following steps: the method comprises the steps that a parturient takes a bladder lithotomy position, vulva is disinfected conventionally, an operator wears sterile gloves, a middle finger and an index finger of one hand stretch into a cervical canal to check the cervical dilatation condition, the size of a amniotic sac is known, the other hand holds tissue forceps to slightly clamp the amniotic sac through the middle of the two fingers of the previous hand and then withdraw from the cervix and the vagina, and the previous hand stays at the original position to wait for amniotic fluid to flow out. However, the conventional operation is performed by means of an instrument by touch under non-direct vision, which is inconvenient, and the tissue forceps are sharp and easily injure the vaginal wall, cervical tissue, fetal scalp and the like of the parturient, so that the proficiency of obstetricians and midwives on the handling of the rupture of membranes is very important. Especially, the new doctors are not familiar with the artificial membrane rupture, which not only takes a long time, but also brings more physical and mental discomfort and pressure to the puerpera, and increases the risk of self injury.

According to clinical experience, when a new doctor carries out artificial membrane rupture, due to insufficient proficiency, the time is often consumed for a long time, the damage to a pregnant woman is easily caused, and the discomfort and the tension of the pregnant woman are easily increased. Meanwhile, the failure of multiple manual membrane rupture operations also increases the frustration and self-doubt of new physicians. The design of a product provides a direct viewing condition, further reduces the difficulty of the artificial membrane rupture, and is beneficial to pregnant women and new doctors.

Conventionally, a vaginal speculum is used to observe the vaginal and cervical conditions. The disposable vaginal speculum or the recyclable vaginal speculum is hard in material, and the disposable vaginal speculum or the recyclable vaginal speculum can enter the vagina of a woman to cause discomfort to the woman. The designed product is soft in material, small in initial volume, capable of slowly expanding the vagina and the cervix, capable of providing a buffering process for women, capable of improving the experience satisfaction of women and more humanized.

Disclosure of Invention
