Abstract
The utility model discloses a novel membrane breaking device, belonging to the auxiliary medical tool in the obstetrical department. The novel membrane breaking device comprises an airbag, a connecting pipe, a puncture needle, a piston, a pressure regulation valve, a puncture needle limiting block, a piston limiting block, a pressure sensor and a bushing, wherein the airbag is fixedly arranged on the tail end of the bushing through the connecting pipe, the connecting pipe is provided with the pressure regulation valve, the piston limiting block is arranged on the inner wall of the bushing to be close to the middle position of the bushing, and the puncture needle limiting block is arranged on the inner wall of the front end of the bushing. The novel membrane breaking device is reasonable in design. The extension length of the puncture needle can be effectively prevented through the pressure sensor, the piston limiting block and the puncture needle limiting block.
Description
Technical field
This utility model belongs to obstetrics medical treatment aid, particularly a kind of novel membrane-repturing device.
Background technology
In the middle of the department of obstetrics and gynecology clinical treatment, run into the puerpera of active phase uterine inertia and uterine contraction difficulty through regular meeting; generally carry out artificial rupture of membrane ability ordinary production for this class puerpera; so-called artificial rupture of membrane is exactly the amniotic membrane that uteri position is torn in the mode means intervention of thinking thought; so that the medical personnel observes the amniotic fluid color, strengthens uterine contraction, shortens the production time to reduce the discomfort that the puerpera causes because of production; and the mode of artificial rupture of membrane generally adopts the direct rupture of membranes of operating theater instruments at present; this type of rupture of membranes mode exists low precision, injures safety issues such as fetus and puerpera easily.
The utility model content
Technical assignment of the present utility model is to provide a kind of novel membrane-repturing device at above prior art deficiency.
The technical scheme that its technical problem that solves this utility model adopts is a kind of novel membrane-repturing device, comprise air bag, connection tube, puncture needle, piston, pressure regulator valve, the puncture needle limited block, the piston limited block, pressure inductor and sleeve pipe, wherein said air bag is fixedly installed on tube ends by connection tube, and described connection tube is provided with pressure regulator valve, described piston is positioned at sleeve pipe, described puncture needle is fixedlyed connected with piston, described piston limited block is arranged near on the internal surface of sleeve pipe in sleeve pipe centre position, described puncture needle limited block is arranged on the sleeve pipe front inner wall, and wherein the design of piston limited block and puncture needle limited block can guarantee that the puncture needle extension elongation is within the safety range.
Further, described puncture needle centre position goes out to be fixed with block.
Further, a side relative with puncture needle on the described piston is provided with pressure inductor, and pressure inductor can in time be reminded the operator when puncture needle is worn out film.
This utility model is reasonable in design, and wherein pressure inductor, piston limited block and puncture needle limited block all effectively prevent the puncture needle extension elongation.
Description of drawings
Fig. 1 is this utility model structural representation.
