Technical field
The present invention relates to gynicologycal medical instrument field, specially a kind of gynemetrics's film breaking unit and its application method.
Background technique
Artificial rupture of membrane is relatively conventional a kind of induced labor mode during spontaneous labor, i.e., tears palace by artificial mode
Amnion at mouthful, to observe amniotic fluid color, to reinforce uterine contraction, acceleration progress of labor.Currently, being clinically often used pricker carries out the behaviour
Make, pricker used is common medical needle, specific operation process are as follows: medical staff's hand wears the gloves that disappear, middle finger and index finger clamping thorn
Needle probes into birth canal, finds out by finger and judges rupture of membranes position and rupture of membranes opportunity, and then thumb force pushes pricker to keep pricker point sliding
Broken amnion realizes rupture of membranes.
This operation using hand-held pricker artificial rupture of membrane, be easy to cause pricker to wander off, influences accuracy and the behaviour of indagation
The sensitivity of work, sharp pricker are also easy to cause to damage to birth canal, increase the probability of infection；Hand-held pricker carries out artificial simultaneously
Rupture of membranes needs more fingers to probe into birth canal jointly, can not be operated when cervix is less than 3 centimetres, time-consuming and laborious, increases puerpera
Sense of discomfort, and be easy amniotic fluid outflow after puncturing, can not retain and extract, contaminated operation environment brings pole for medical staff
Big inconvenience.
