Description

Improper fetal position aids

The new model relates to an auxiliary appliance, especially an auxiliary appliance for fetal position irregularity, which is aimed at vaginal production in the breech position and assists the delivery of the head of the fetus.

The so-called breech vaginal delivery means that the fetus is delivered from the feet or buttocks first out of the vagina, then the body is delivered out of the vagina, and the head of the fetus is delivered last. About 1% of fetuses, when the head is finally delivered, the back of the head interferes with the mother's pubic bone, causing dystocia. However, the condition that the back of the fetus's head is stuck in the mother's pubic bone needs to be eliminated quickly, otherwise the fetus may be hypoxic. In the past, most of the practice is to press the mother’s lower abdomen with bare hands and indirectly press the fetus’s head to make the fetus’s head close to the chest to relieve the pubic bone of the mother from the back of the head. Or directly by the doctor. The staff put their hands into the vagina of the parturient to press the chin of the fetus, hoping to make the head of the fetus close to the breast of the fetus, so that the back of the head can be free from the interference of the pubic bone of the parturient, but this move depends on the experience of the doctor and nurse, and sometimes it fails. It is possible to adopt invasive methods or even surgery, which increases the risk of maternal and fetal injury.

The present invention provides an auxiliary device for malposition of the fetus, which is especially aimed at vaginal delivery in the breech position. After the buttocks, legs and body of the fetus are delivered in sequence, the final delivery of the head may be difficult. The device can help doctors and nurses to quickly eliminate the condition that the back of the fetus's head is stuck in the pubic bone of the parturient.

A fetal misalignment aid disclosed in an embodiment of the present invention is suitable for a breech fetus delivered from the vagina, and is used to be set on the head of the fetus to assist the head of the fetus to be delivered. Because during breech vagina delivery, the fetus’s buttocks and feet are delivered first, and the fetus’s head is delivered last. It is possible that the angle of the fetus’s head is not correct, and the fetus’s head is jammed by the mother’s pelvis, causing difficult delivery. The assistive tool for fetal malposition includes a plurality of assembling pieces and at least one handle. These assembling pieces are grouped in sequence to form an arc-shaped plate, and the arc-shaped plate is arranged on the head of the fetus. The handle is arranged on one side of the arc-shaped plate. The handle is used to receive an external force to drive the head of the fetus to move relative to the body of the fetus, so that the head of the fetus can be separated from the pelvis and delivered smoothly.
