Description
Technical field
The present invention relates to the field of medical instrument technology, are specifically related to a kind of amniotic fluid rupture of membranes drainage of obstetrics and gynecology department anti-overflow
Device.
Background technique
Currently, in clinical obstetrics, it, generally will be by artificial broken for the puerpera of active period uterine inertia and uterine contraction difficulty
The method help of film produces.Artificial rupture of membrane, exactly artificial mode, which is intervened, tears uteri position fetal membrane, to observe amniotic fluid color,
Reinforce uterine contraction, accelerate progress of labor.In clinical manipulation, amnion generally is sucked using film breaking unit negative pressure, is pierced using membrane puncture needle
Broken amnion, sucks amniotic fluid later, and since film breaking unit is protruded into private parts for convenience, film breaking unit front end is typically small,
Therefore after puncturing amnion, amniotic fluid may overflow on front side of film breaking unit to be caused to infect, it is therefore necessary to be improved.
Chinese patent CN207445018U discloses a kind of gynemetrics's film breaking unit, including liquid storage cylinder, further includes from liquid storage
The push rod that tube rear end protrudes into, push rod are fixedly arranged at the front end with the piston that air-tight movable is located in liquid storage cylinder, and rear end is fixed with pushing block, liquid storage
