Strengthen uterine contraction, accelerate progress of labor.In clinical manipulation, the general film breaking unit using syringe cylinder structure inhales amniotic fluid, but is sucking
During amniotic fluid, fetal membrane persistently by vacuum suction, makes pricker persistently work, and easily triggers dangerous, it is therefore necessary to changed
Enter.
The content of the invention
The purpose of this utility model is to be directed to the above-mentioned problems in the prior art, there is provided a kind of rupture of membranes operation is more
Gynemetrics's midwifery film breaking unit of safety.
The purpose of this utility model can be realized by following technical proposal：A kind of gynemetrics's midwifery film breaking unit, it is special
Sign is：Including the cylindric outer barrel and inner cylinder being coaxially disposed, outer tube inner wall is bonded with inner tank theca, in addition to from interior tube rear end
The bar-shaped piston bar stretched into inner cylinder, piston rod bar wall are bonded with the activity of inner cylinder inwall, and inner cylinder front end is located in outer barrel, and close
Outer cylinder front end is set, and inner cylinder front end is provided with pricker, and interior tube rear end is located at outside outer barrel, and is fixed with ring-shaped handle ring, and ring of shaking hands
Offseted with outer tube rear end, and pricker is located in outer barrel.
Outer cylinder front end is withstood into fetal membrane, piston rod of pulling back, drives absorbed portion fetal membrane, fetal membrane is encountered pricker and is punctured, it
Handle ring is pulled afterwards, pricker is separated with fetal membrane, and is moved towards outer tube rear end, pulls piston rod afterwards, can be smoothly amniotic fluid
It is drawn into inner cylinder, because pricker can utilize inner cylinder post-tensioning after rupture of membranes, therefore avoids too destroying fetal membrane so that rupture of membranes is more
Add safety.
In a kind of above-mentioned gynemetrics's midwifery film breaking unit, outer tube inner wall is coaxially fixed with annular stop ring, spacing ring
Some pin holes, pricker and inner cylinder diameter parallel are provided with, and when ring of shaking hands offsets with outer tube rear end, pricker passes through pin hole, and
Set towards outer cylinder front end, and stretchy handle ring, pricker is separated with pin hole.
In a kind of above-mentioned gynemetrics's midwifery film breaking unit, inner cylinder is fixedly arranged at the front end with annular baffle ring, and pricker is fixed on
On baffle ring top surface, and when baffle ring top surface and spacing ring bottom surface fit, described pricker is located in pin hole, shake hands ring and outer barrel
Rear end offsets.
Spacing ring and baffle ring, which coordinate, plays position-limiting action, avoids pricker from too stretching out, while spacing ring can also play resistance
Keep off the effect of fetal membrane.
In a kind of above-mentioned gynemetrics's midwifery film breaking unit, described inner cylinder and outer barrel are that transparent material is made.
Compared with prior art, the utility model has the following advantages that：
Outer cylinder front end is withstood into fetal membrane, piston rod of pulling back, drives absorbed portion fetal membrane, fetal membrane is encountered pricker and is punctured, it
Handle ring is pulled afterwards, pricker is separated with fetal membrane, and is moved towards outer tube rear end, pulls piston rod afterwards, can be smoothly amniotic fluid
It is drawn into inner cylinder, because pricker can utilize inner cylinder post-tensioning after rupture of membranes, therefore avoids too destroying fetal membrane so that rupture of membranes is more
Add safety.

Embodiment
It is specific embodiment of the utility model and with reference to accompanying drawing below, the technical solution of the utility model is made further
Description, but the utility model is not limited to these embodiments.
As shown in figure 1, a kind of gynemetrics's midwifery film breaking unit of the utility model, including the cylindric outer barrel 1 being coaxially disposed
With inner cylinder 2, the inwall of outer barrel 1 is bonded with the outer wall of inner cylinder 2, in addition to the bar-shaped piston bar 3 stretched into from the rear end of inner cylinder 2 in inner cylinder 2, living
The bar wall of stopper rod 3 is bonded with the activity of the inwall of inner cylinder 2, and the front end of inner cylinder 2 is located in outer barrel 1, and is set close to the front end of outer barrel 1, before inner cylinder 2
End is provided with pricker 21, and the rear end of inner cylinder 2 is located at outside outer barrel 1, and is fixed with ring-shaped handle ring 22, and shake hands ring 22 and the rear end of outer barrel 1
Offset, and pricker 21 is located in outer barrel 1.
Further, the inwall of outer barrel 1 is coaxially fixed with annular stop ring 11, and spacing ring 11 is provided with some pin holes 12, thorn
Pin 21 and the diameter parallel of inner cylinder 2, and when ring 22 of shaking hands offsets with the rear end of outer barrel 1, pricker 21 pass through pin hole 12, and towards outer barrel
1 front end is set, and stretchy handle ring 22, pricker 21 is separated with pin hole 12.Inner cylinder 2 is fixedly arranged at the front end with annular baffle ring 23, and
