Description

Technical Field

[0001] The utility model belongs to the technical field of auxiliary appliances, and more specifically, particularly relates to an artificial membrane rupture device. Background Art

[0002] Clinically, many women fail to rupture membranes naturally and need doctors to assist in artificial rupture of membranes. Artificial rupture of membranes is to artificially rupture the amniotic membrane at the cervical os, discharge amniotic fluid, lower the presenting part, stimulate the cervix, cause uterine contraction, dilate the cervical os, and accelerate the progress of labor. It is a common method of inducing labor during natural delivery.

[0003] Based on the above, the inventors have found the following problems: in the current traditional method of artificial rupture of membranes, the needle is usually clamped between the index finger and the middle finger to enter the vagina for artificial rupture of membranes. This method cannot accurately control the depth of needle insertion, which may injure the fetus. After rupture of membranes, it is necessary to use fingers to enlarge the ruptured membrane opening, which is very inconvenient. After rupture of membranes, a large amount of amniotic fluid will gush out. The outflowing amniotic fluid needs to be collected and the properties and color of the amniotic fluid need to be observed. The traditional method is not conducive to collecting the amniotic fluid well, resulting in a large loss of amniotic fluid, which is not conducive to observing and measuring the amount of amniotic fluid.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and an artificial membrane rupture device is provided to achieve a purpose with greater practical value. Utility Model Content
