Abstract
The utility model relates to an obstetrics membrane breaker which comprises a sleeve, wherein a casing is connected to one end of the sleeve; a connecting base is connected to the other end of the sleeve; the sleeve is internally provided with a piston; a sucker is arranged at the other end of the casing; the casing is internally provided with a puncture needle; the puncture needle is fixedly connected with the piston; a first connecting tube and a second connecting tube are arranged at one end of the sleeve, connected with the casing; a sealing plug is arranged at the other end of the first connecting tube; an airbag is connected to the other end of the second connecting tube; a one-way valve is arranged on the second connecting tube; a bolt is in threaded connection with the connecting base; the bolt is rotatably connected with the piston. When the obstetrics membrane breaker is used, the puncture needle is positioned inside the casing, then hurt to a parturient is avoided; negative pressure can be formed inside the casing through the airbag, the embryonic membrane can be sucked through the sucker, after the bolt is rotated, the puncture needle can pierce the embryonic membrane, and a fetus is prevented from being hurt, so that the obstetrics membrane breaker is convenient to use and is safe and reliable.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, specifically relates to a kind of membrane rupturing device used in obstetrics.
Background technology
Rupture of membranes is operation commonly used in obstetrics of hospital, rupture of membranes instrument commonly used in Hospitals at Present is puncture needle, the doctor is very inconvenient when operating with puncture needle, requirement to the doctor is higher, and while puncturing fetal membrane, the degree of depth is difficult for grasping, thrust the degree of depth and cross deeply and may damage fetus, puncture needle during by vagina easily to the vagina injury, dangerous.
The utility model content
Problem to be solved in the utility model is to provide a kind of membrane rupturing device used in obstetrics esy to use, safe and reliable, that can not damage puerpera and fetus.
For addressing the above problem, the technical scheme that this utility model adopts is: a kind of membrane rupturing device used in obstetrics, comprise sleeve, one end of described sleeve is connected with sleeve pipe, the other end of described sleeve is provided with Connection Block, in described sleeve, be provided with piston, the other end of described sleeve pipe is provided with suction nozzle, in described sleeve pipe, be provided with puncture needle, described puncture needle is fixedly connected with piston, described sleeve and a telescopic joint end are provided with the first connection tube and the second connection tube, the other end of described the first connection tube is provided with sealing-plug, the other end of described the second connection tube is connected with air bag, on described the second connection tube, be provided with check valve, bolt has been threaded on described Connection Block, described bolt and piston are rotatably connected.
A kind of concrete prioritization scheme, be provided with scale on described sleeve, can control by scale the degree of depth that puncture needle enters, thereby avoid fetus is damaged.
This utility model is taked above technical scheme, have the following advantages: during use, puncture needle is positioned at sleeve pipe, can avoid the puerpera is damaged, and can make in sleeve pipe to form negative pressure by air bag, by suction nozzle, fetal membrane is held, then swivel bolt, make puncture needle that fetal membrane is punctured and gets final product, and can not hurt fetus, easy to use, safe and reliable.
The utility model is described in further detail below in conjunction with drawings and Examples.
