Description
Technical field
The present invention relates to obstetrics' medical instruments field, it is specifically related to a kind of vacuum suction and manually breaks fetal membrane device.
Background technique
Pregnant woman is frequently encountered uterine inertia, fetal distress, prolonged labor when giving a birth, and understands amniotic fluid character, adds
Fast progress of labor, it usually needs manually puncture fetal membrane, the method for artificial rupture of membrane is commonly doctor and holds disposable syringe at present
Syringe needle enters vagina and punctures fetal membrane.But use disposable syringe there are many drawbacks, the depth of piercing is unable to accurately control,
It is easy to pierce fetus, pregnant woman's vaginal wall and medical staff.And since fetus wriggles in amnion, the position of piercing is bad really
It is fixed, it is easy thorn partially, and pass through vagina when amniotic fluid outflow, is easy to be influenced by vaginal fluid, thimerosal, bleeding, Wu Fazhun
Really judge the character of amniotic fluid.
Summary of the invention
The purpose of the present invention is to overcome defect in above-mentioned technology, provides the device that fetal membrane is manually broken in a kind of vacuum suction, mentions
High security realizes one-handed performance.
The invention adopts the following technical scheme: a kind of vacuum suction manually break fetal membrane device, it include sleeve, push rod,
Piston, pricker, assister bar, limit casing, the sleeve upper end opening, lower end are equipped with pricker, and pricker is connected to sleeve, institute
The push rod lower end connection installation piston stated, is placed in sleeve, a slide opening, the assister bar one is provided on the side wall of sleeve
End is connected on push rod, and the other end extends sleeve by slide opening, and the lower end of the sleeve is connected and installed with limit casing.
Preferably, the upper port of the sleeve extends inward as a circular press section.
Preferably, the lower end of the limit casing lower edge and pricker is in an elevation of water.
Preferably, the assister bar is set as being adjacent to the trigonal slider of sleeve outer wall in the one end for extending sleeve.
Preferably, the limit casing is pyramidal structure.
Preferably, the lower end edge of the limit casing is equipped with silica gel ring.
The beneficial effects of the present invention are: whole device can easily enter vagina, form negative pressure by upper push piston,
It is attracted to fetal membrane on puncture needle, to puncture fetal membrane, avoids damage to fetus and pregnant woman's vaginal wall.Rupture of membranes afterwaters enter should
Whether device is not influenced by vaginal fluid, thimerosal, bleeding, accurate judgement amniotic fluid character, if limpid, have meconium dirty
Dye etc., and registration, one-hand operation.
Detailed description of the invention
Fig. 1 is the schematic diagram of one embodiment of the present of invention.
Specific embodiment
The present invention is further illustrated for embodiment with reference to the accompanying drawing.
As shown in Figure 1, a kind of vacuum suction manually break fetal membrane device, it include sleeve 1, push rod 2, piston 3, pricker 4,
Assister bar 5, limit casing 6,1 upper end opening of sleeve, lower end are equipped with pricker 4, and pricker 4 is connected to sleeve 1, described
2 lower end of push rod connection installation piston 3, is placed in sleeve 1, a slide opening, the assister bar 5 is provided on the side wall of sleeve 1
One end is connected on push rod 2, and the other end extends sleeve 1 by slide opening, and the lower end of the sleeve 1 is connected and installed with limit sleeve
Pipe 6.
A circular press section 11 is extended inward as in the upper port of the sleeve 1.Facilitate the hair of finger
Power, and guarantee that whole device can smoothly enter into vagina.
4 lower ends of 6 lower edge of limit casing and pricker are in an elevation of water.Such design can use
When prevent plowing from vaginal wall, improve safety.
The assister bar 5 is set as being adjacent to the trigonal slider 51 of sleeve outer wall in the one end for extending sleeve 1.This structure
Design ensure that whole device can smoothly enter into vagina.
The limit casing 6 is pyramidal structure.The lower end edge of the limit casing 6 is equipped with silica gel ring 61.?
When operation, amnion can be adjacent to, when piston upwards, guarantee will not gas leakage, negative pressure is formed in spacing collar 6, to make
Amnion is heaved upwards, and pricker 4 is enabled to puncture piercing amnion, extracts amniotic fluid.
