Description

TECHNICAL FIELD

[0001] The utility model relates to the field of medical equipment, in particular to a device for protecting the vulva during childbirth. BACKGROUND

[0002] Vulvar laceration is a common phenomenon in clinical practice, and most puerperas will have vulvar laceration, especially primiparae, which is mainly due to the poor elasticity of the vulva of primiparae. When the head of the fetus passes through the perineal body, the descent of the fetal head will exert a certain pressure on the perineal body. When the perineal body reaches the limit, it will cause the vulva to tear. Vulvar laceration will have a great adverse effect on the physical and mental health of puerperas and will also reduce the quality of life after childbirth.

[0003] Therefore, there is a need for a technical solution to solve the technical problem of easy perineal laceration when the maximum diameter of the fetal head is delivered through the vaginal orifice or the puerpera exerts excessive force during childbirth. SUMMARY

[0004] The utility model aims at overcoming the technical problem of easy perineal laceration when the maximum diameter of the fetal head is delivered through the vaginal orifice or the puerpera exerts excessive force during childbirth, and provides a device for protecting the vulva during childbirth.

[0005] The utility model provides a device for protecting the vulva during childbirth, which comprises a patch, the patch is provided with an avoidance window, the patch comprises a protective layer and a connecting layer, the connecting layer is arranged on one side of the protective layer, the protective layer is a structure made of elastic material, and the connecting layer has adhesion for sticking around the perineum of puerpera.

[0006] The utility model relates to a device for protecting the vulva during childbirth. During use, one side of the connecting layer of the patch is stuck around the perineum of puerpera, and the vaginal orifice of puerpera is exposed through the avoidance window. During childbirth, the patch with elasticity expands along with the vaginal orifice. On the one hand, the protective layer provides a certain contraction force for the vaginal orifice. When the vaginal orifice expands to a certain extent, the contraction force provided by the protective layer increases, thereby reducing the problem of vaginal laceration caused by expansion to the limit. On the other hand, the protective layer has elasticity, which plays a buffering role during the expansion of the vaginal orifice. Compared with the prior art, the utility model increases the elasticity of the skin around the vaginal orifice, thereby reducing the problem of perineal laceration caused by the limit tension and compression of the perineal body during vaginal childbirth.

[0007] Preferably, the patch is provided in the shape of U.

[0008] The patch adopts a U-shaped structure, the avoidance window is formed in the middle of the U-shaped structure, and the patch can be installed around the vulva of puerpera during use. The bottom of the U-shaped structure is located below the perineal body, and the two sides of the U-shaped structure are located on both sides of the vulva, so that the parts that may be torn during childbirth are comprehensively protected.

[0009] Preferably, a gap is provided between the side edge of the connecting layer and the side edge of the protective layer.

[0010] The connecting layer is laid on one side of the protective layer for adhesion to the skin of the parturient woman, and by providing a gap between the edge of the connecting layer and the edge of the protective layer, the entire protective layer is prevented from being adhered to the skin of the parturient woman, facilitating the tearing of the patch from the skin of the parturient woman after use.

[0011] Preferably, the patch is a structure made of silicone.

[0012] Silicone has excellent elastic properties and can stretch and twist adaptively with the expansion of the vaginal orifice, and can provide a perineal body contraction force when the vaginal orifice of the parturient woman expands. In addition, silicone has good skin-friendliness and will not cause irritation or harm to the skin, and has good plasticity and can be processed into various shapes as needed.

[0013] Preferably, the thickness of the protective layer is set as d, 1mm≤d≤3mm.

[0014] The thickness of the protective layer is mainly designed to consider the change of the elastic limit of the patch caused by the thickness. The thickness of the protective layer is set to be less than 3mm to avoid the normal expansion of the vagina being greatly affected by the excessive elasticity of the protective layer, and the thickness of the protective layer is set to be more than 1mm to enable the protective layer to have sufficient elasticity and play a good buffering role in the expansion of the vagina before the perineum reaches the tearing limit.

[0015] Preferably, the width of the protective layer is set as c, 1cm≤c≤2cm.

[0016] The width of the protective layer needs to be considered in terms of the size of the elasticity and the problem of limited adhesion of the protective layer around the vaginal orifice of the parturient woman. The width of the protective layer is set to be less than 2cm to ensure that the protective layer can be smoothly adhered around the vaginal orifice of the parturient woman, and at the same time, not to cause excessive tightening force on the skin of the parturient woman, ensuring that the vaginal orifice of the parturient woman can expand normally. The width of the protective layer is set to be more than 1cm to ensure that the patch has sufficient elasticity to play a buffering role in the expansion of the vagina of the parturient woman.

[0017] Preferably, the patch further comprises an oil paper layer, which is arranged on the side of the connecting layer away from the protective layer.

[0018] The oil paper protects the connecting layer to prevent the connecting layer from being contaminated during non-use, and ensures that the connecting layer has good adhesion when used.

[0019] Preferably, the side edge of the oil paper layer extends beyond the side edge of the connecting layer.

[0020] Convenient in use pull out the side edge of oil paper layer, tear off the oil paper layer from the connecting layer, the operation is more convenient.

[0021] Compared with the prior art, the utility model has the beneficial effects of:

[0022] 1.The patch of the present application is installed at the vaginal orifice of a puerpera, and the elastic patch expands with the vaginal orifice during the delivery process, thereby providing a certain contraction force to the vaginal orifice and perineal body; when the vaginal orifice expands to a certain extent, the contraction force provided by the protective layer increases, thereby reducing the problem of vaginal tearing caused by expansion to the limit.

[0023] 2.The protective layer has elasticity and plays a buffering role during the expansion of the vaginal orifice, thereby increasing the elasticity of the skin around the vaginal orifice and reducing the problem of perineal body tearing caused by the tension limit of the perineal body due to the fetal head during vaginal delivery.
