This utility model relates to a kind of obstetrics and gynecology department medical apparatus and instruments, particularly a kind of negative pressure absorbing formula department of obstetrics and gynecology film breaking unit.
Background technology
At present, in department of obstetrics and gynecology clinical practice, for the puerpera of active phase uterine inertia and uterine contraction difficulty, general needs helps it to puncture amniotic membrane by artificial mode, to help it to produce, owing to lacking the rupture of membranes instrument of specialty, medical personnel generally adopt vascular forceps to carry out rupture of membranes, in the process of rupture of membranes, because the tip of vascular forceps is sharp keen not, be difficult to fixing for amniotic membrane absorption, so be difficult to the degree of depth controlling to puncture amniotic membrane simultaneously, not only rupture of membranes efficiency is low, also other can be caused to injure to anemia of pregnant woman.
Summary of the invention
Problem to be solved in the utility model is: provide the negative pressure absorbing formula department of obstetrics and gynecology film breaking unit that can also control the rupture of membranes degree of depth while that a kind of structure is simple, convenient adsorbing amniotic membrane and puncture.
In order to solve the problems of the technologies described above, negative pressure absorbing formula department of obstetrics and gynecology film breaking unit of the present utility model, comprise cylindrical shell, through hole is provided with in described cylindrical shell, a rupture of membranes bar is inserted with in described through hole, the top of described rupture of membranes bar is evenly equipped with several pointed cones, vacuum chamber is provided with in described rupture of membranes bar, the end of described rupture of membranes bar is fixed with one piece of limited block, the rear portion of described limited block is fixed with handle, described handle is connected with suction pipe, the end of described suction pipe is connected with vacuum generator, described suction pipe is connected with vacuum chamber, described suction pipe is provided with controlled valve, sealing ring is provided with between the entrance point of described through hole and rupture of membranes bar.
Conveniently be inserted in birth canal by cylindrical shell, negative pressure absorbing formula department of obstetrics and gynecology film breaking unit of the present utility model, the first half of described cylindrical shell is taper.
In order to rupture of membranes bar slide anteroposterior in the through hole of cylindrical shell can be guided smoothly, can automatically realize automatically reseting of rupture of membranes bar after rupture of membranes simultaneously, negative pressure absorbing formula department of obstetrics and gynecology film breaking unit of the present utility model, described through hole internal fixtion has guide collar, described rupture of membranes bar is inserted in guide collar, the rupture of membranes bar at described guide collar rear is fixed with back-up ring, between described back-up ring and guide collar, is provided with back-moving spring.
Thrust the degree of depth of amniotic membrane to control rupture of membranes bar, negative pressure absorbing formula department of obstetrics and gynecology film breaking unit of the present utility model, the length of described pointed cone is 1-2mm.
The beneficial effect that this utility model obtains is: (1) structure is simple; (2) when concrete use, cylindrical shell is inserted in the birth canal of anemia of pregnant woman, then controlled valve is opened, under the effect of vacuum generator, by suction pipe, the air in vacuum chamber is siphoned away, make to form negative pressure in vacuum chamber, then promote handle, make the slippage forward of rupture of membranes bar, when rupture of membranes bar stretches out in after outside cylindrical shell, owing to being negative pressure in vacuum chamber, thus can be firm be held by the amniotic membrane in anemia of pregnant woman's body, finally rotates rupture of membranes bar, utilizes pointed cone to be punctured by amniotic membrane, whole rupture of membranes process is very simple, is easy to operation; (3) first half of cylindrical shell is taper, is convenient to cylindrical shell to insert in birth canal; (4) through hole internal fixtion has guide collar, and rupture of membranes bar is inserted in guide collar, thus when driving rupture of membranes bar is movable, due to the guide effect of guide collar, the glide direction of rupture of membranes bar can be avoided to occur skew; The rupture of membranes bar at guide collar rear portion is fixed with back-up ring, is provided with back-moving spring between back-up ring and guide collar, thus after rupture of membranes completes, unclamp handle, under the effect of the elastic force of back-moving spring, rupture of membranes bar can automatically reset; (5) length of pointed cone is 1-2mm, is convenient to control the degree of depth that rupture of membranes bar thrusts amniotic membrane, avoids causing other to injure to anemia of pregnant woman.
