Description

Vaginal expansion device, device for placing the device, and method for using the device

technical field

The invention belongs to the field of medical equipment, and in particular relates to a vaginal dilation device, a device for placing the device and a method for using the device.

Background technique

In order to avoid prolonged labor and promote uterine contractions, artificial rupture of membranes and application of oxytocin during labor are common interventions. The technique of artificial membrane rupture was first proposed by a British obstetrician Thomas Denman in the middle of the 18th century. Medical operation, making the amniotic fluid flow out, can strengthen the uterine contraction and accelerate the labor process when the progress of the labor process is stagnant. It can also be used to observe the properties of the amniotic fluid to evaluate whether the fetus is hypoxic. It is a medical intervention that is often used during vaginal delivery. widely used in developing countries. Artificial rupture of membranes may be considered first in cases of uterine atony, prolongation of the incubation period, and abnormal fetal heart rate monitoring. Usually clinically, artificial membrane rupture is performed using tissue forceps and needles. Studies have shown that artificial membrane rupture using tissue forceps greatly reduces the incidence of operator injury, maternal injury, and fetal injury, and the success rate of artificial membrane rupture using tissue forceps is also higher than that of artificial membrane rupture using needles. Therefore, artificial membrane rupture is often performed clinically with tissue forceps.

Artificial membrane rupture method: the puerpera takes the bladder lithotomy position, routinely disinfects the vulva, the operator wears sterile gloves, inserts one middle finger and index finger into the cervical canal, checks the dilatation of the cervix, and understands the size of the amniotic sac, and holds tissue forceps with the other hand Gently pinch the amniotic sac between the two fingers of the previous hand and exit the cervix and vagina. The previous hand stays in place and waits for the amniotic fluid to flow out. However, this routine operation is often inconvenient under non-direct vision with the help of tactile instruments, and the tissue forceps are sharp, which can easily damage the vaginal wall, cervical tissue, and fetal scalp of the parturient. The proficiency of membrane rupture technology is very important. Especially novice doctors are often unfamiliar with artificial membrane rupture, which not only takes a long time, but also brings more physical and mental discomfort and pressure to the parturient, and also increases the risk of self-injury.

According to clinical experience, novice doctors often take a long time to perform artificial membrane rupture due to lack of proficiency, and it is easy to cause damage to pregnant women, which can easily increase the discomfort and tension of pregnant women. At the same time, repeated failures of artificial membrane rupture also increased the frustration and self-doubt of novice physicians. Designing a product to provide direct vision conditions further reduces the difficulty of artificial membrane rupture, which is beneficial to both pregnant women and novice physicians.

Usually use a speculum to observe the vagina and cervix. Regardless of whether it is a disposable speculum or a recyclable speculum, the material is relatively hard, and its entry into the female vagina will more or less cause female discomfort. Design a product with soft material and small initial volume, slowly expand the vagina and cervix, buffer the process for women, improve women's experience satisfaction, and be more humane.

Contents of the invention

In view of the above-mentioned prior art, the object of the present invention is to provide a vaginal dilation device, a device for placing the device and a method for using the device.

Furthermore, the tiles are made of magnetic materials, for example, magnets can be used to increase the support stability of the tiles and have a simple structure.

Further, the placement device of the venereal expansion device includes a turntable, a base and a plurality of sliders, the inner surface of the base is in contact with the sliders and the end surface of the base is in contact with the turntable, the turntable can rotate relative to the base and is provided with a dovetail groove so that the sliders It can move linearly on the same conical surface relative to the turntable. Multiple sliders are distributed in a ring and the outer surface is provided with a tapered external thread that matches the tapered internal thread on the inner surface of the base so that the slider can move along the conical surface after the base rotates. There are axial movement and radial movement, and the outer end of the slider is provided with a positioning rod that can be inserted into the positioning hole provided on the tile, so that the reliability of the design is greatly improved.

Furthermore, the outer surface of the turntable is provided with a non-slip structure, and the outer surface of the slider is provided with a scale so that the stretchable length of the slider can be intuitively converted into the expansion of the diameter, and rubber can be wrapped or an uneven surface can be set to increase friction, so that It is more convenient and flexible to use.

Furthermore, a vibrating structure is provided in the base, which can improve the comfort of use.

A method of using a vaginal dilation device. First, apply lubricant evenly on the lubricating layer, and let it stand for five minutes to allow the lubricant to be fully absorbed by the lubricating layer. The vaginal device is enlarged, and the vibrating device is turned on when the user feels a slight tearing sensation. After vibrating for five minutes, it is left to stand for five minutes and then enlarged by 6mm. After that, it is enlarged by 3mm each time until the user feels a certain pain, and finally the membrane is ruptured. After surgery, use the placement device to shrink the vaginal dilation device and take it out.
