Description

Clinical rupture of membranes device of using of gynaecology and obstetrics

Technical Field

The utility model relates to a clinical auxiliary assembly field of gynaecology and obstetrics, concretely relates to clinical rupture of membranes device of using of gynaecology and obstetrics.

Background

The artificial rupture of the membrane is a common induced labor mode in the natural delivery process, namely the amniotic membrane at the uterine opening is torn in an artificial mode so as to observe the color of amniotic fluid, strengthen uterine contraction and accelerate the progress of the labor process. At present, the puncture needle is commonly used for carrying out the operation clinically, the used puncture needle is a common medical needle head, and the specific operation process is as follows: medical personnel wear the gloves that disappear with the hand, middle finger and forefinger centre gripping felting needle probe into birth canal, rely on finger to know to judge rupture of membranes position and rupture of membranes opportunity, then the thumb pushes the felting needle hard to make the puncture needle point slide and break the amnion and realize rupture of membranes, above-mentioned operating method is at the in-process that the pjncture needle got into birth canal, because the pjncture needle need exert certain power direction and can move forward, very easily because the application of force is inhomogeneous and leads to the felting needle to walk partially in this in-process, and then causes the puncture needle head to stab the birth.
