在产妇分娩过程中第二产程延长,可危及胎儿生命,为了缩短第二产程,保障母婴安全,我们研制了一种头位助产器,它不但能扩张会阴,还能起胎头负压吸引作用,使第二产程明显缩短,以减少母婴损伤。现介绍如下。结构和原理头位助产器是由会阴扩张和胎头负压吸引两部分组成。外面为不锈钢制成的四叶扩张片,闭合时呈圆桶状,扩张后呈圆台状,最大直径为9cm,扩张片里面为一硅胶材料制成的吸头,吸头下面有螺纹杆构成负压吸引装置,有支杆连于扩张片和螺纹之间,由调整把和拉块相对转动,使扩张片扩张(如图)。
In the process of maternal delivery of the second stage of extension, can endanger the life of the fetus, in order to shorten the second stage of labor, to ensure the safety of mother and child, we developed a first-position midwifery, which not only can expand the perineum, but also from negative fetal head Attraction, so that the second stage of labor was significantly shortened to reduce maternal and child injuries. Now introduced as follows. Structure and principle The first bit midwifery is caused by the expansion of the perineum and fetal head suction to attract two parts. The outside is made of stainless steel four-leaf expansion piece, closed when the barrel-shaped, expanded after the round table-shaped, the maximum diameter of 9cm, expansion piece inside a silicone material made of the tip, the tip below the threaded rod constitutes a negative Press suction device, a strut connected between the expansion and the thread between the adjustment and the relative rotation of the slider, the expansion piece expansion (Figure).
