Preferably, it is 1~2cm that the front end of the protective case, which extends beyond the size of the membrane puncture needle,.
Preferably, the protective case is rubber protecting jacket.
Preferably, the accommodating chamber that there is the protective case the past end to be through to rear end, the outer surface of the membrane puncture needle and institute
State the inner surface fitting of accommodating chamber.
The artificial rupture of membrane tool of the utility model can be directly attached on injector syringe nipple use, use process
In, the membrane puncture needle for being arranged with protective case is first extend into the intravaginal of pregnant and lying-in women, the front end of protective case is made to resist uteri position amnion,
Then the piston in injector syringe is pulled out, amnion is sucked in protective case by negative pressure and is contacted with membrane puncture needle, rupture of membranes is made
Needle punctures amnion, to complete rupture of membranes operation.Due to the presence of protective case, when membrane puncture needle extend into pregnant and lying-in women's intravaginal, rise
To protective effect, prevent membrane puncture needle from causing to damage to pregnant and lying-in women's vaginal wall and uterine neck；And amnion is sucked by negative pressure and is protected
Contact with membrane puncture needle after in set and implement to puncture, effectively control membrane puncture needle punctures depth, avoids to its phase of fetus in amnion
It closes tissue to cause to damage, the skill requirement to medical worker is also reduced, so that operation ease and safety are all improved；Separately
Outside, the artificial rupture of membrane tool construction of the utility model is simple, low in cost, and can directly cooperate as disposable medical apparatus
It is used on to the syringe of disposable syringe, it is convenient and healthy.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the artificial rupture of membrane tool of the utility model.
Description of symbols
1 protective case, 2 membrane puncture needle
21 channel, 3 interconnecting piece
Specific embodiment
It should be noted that in the absence of conflict, the spy in embodiment and embodiment in the utility model
Sign can be combined with each other.
In the present invention, it is to be understood that the orientation or positional relationship of the instructions such as term "front", "rear" be based on
Orientation or positional relationship shown in the drawings, it is also corresponding with the orientation or positional relationship of actual use；" inside and outside " refer to relative to
The profile of each component itself it is inside and outside；It is merely for convenience of describing the present invention and simplifying the description, rather than indicates meaning
Device or element must have a particular orientation, be constructed and operated in a specific orientation, therefore should not be understood as practical new to this
The limitation of type.
The utility model is described in detail below with reference to the accompanying drawings and in conjunction with embodiment.
The utility model provides a kind of artificial rupture of membrane tool, which includes interconnecting piece 3,2 and of membrane puncture needle
Protective case 1, the interconnecting piece 3 have the hollow cavity that rear end is through to from front end, and the membrane puncture needle 2 from front end with after being through to
The rear end in the channel 21 at end, the channel 21 is connected to the front end of the hollow cavity, and the hollow cavity is formed in rear end to be used for
It is connected to the connection structure of injector syringe nipple, the protective case 1 is set on the membrane puncture needle 2.
The artificial rupture of membrane tool of the utility model can be directly attached on injector syringe nipple use, use process
In, the membrane puncture needle 2 for being arranged with protective case 1 is first extend into the intravaginal of pregnant and lying-in women, the front end of protective case 1 is made to resist uteri position sheep
Then film pulls out the piston in injector syringe, suck in protective case 1 amnion by negative pressure and contact with membrane puncture needle 2, into
One step pulls out piston to increase negative pressure and membrane puncture needle 2 can be made to puncture amnion, and after amnion punctures, amniotic fluid can be along needle membrane puncture needle
2 channel 21 flows into injector syringe, to prompt medical worker to complete rupture of membranes operation.
In the process, it due to the presence of protective case 1, when membrane puncture needle 2 extend into pregnant and lying-in women's intravaginal, plays protection and makees
With preventing membrane puncture needle 2 from causing to damage to pregnant and lying-in women's vaginal wall and uterine neck；And after amnion is sucked in protective case 1 by negative pressure
It is contacted with membrane puncture needle 2 to implement to puncture, effectively control membrane puncture needle 2 punctures depth, avoids its to fetus in amnion related
Tissue causes to damage, and the skill requirement to medical worker is also reduced, so that operation ease, safety and agility are all mentioned
It is high；In addition, the artificial rupture of membrane tool construction of the utility model is simple, low in cost, and can be straight as disposable medical apparatus
It connects and is used on the syringe for be cooperated to disposable syringe, it is convenient and healthy.
Preferably, the front end of the protective case 1 extends beyond the front end of the membrane puncture needle 2, so that extending into motherhood
After woman's intravaginal, contacting with amnion is protective case 1 rather than membrane puncture needle 2, and protective case 1 is that membrane puncture needle 2 provides longer blocking
Distance is not only more advantageous to the linked groups such as protection pregnant and lying-in women's vagina, uterine neck, but also is conducive to pull out syringe subsequent
Negative pressure is generated in the front of protective case 1 when piston in syringe, is connect with preferably sucking amnion in protective case 1 with membrane puncture needle 2
Touching.
Further, in present embodiment, the front end of the protective case 1 extend beyond the membrane puncture needle 2 size be 1~
2cm, rationally to control depth of the membrane puncture needle 2 in protective case 1, to keep rupture of membranes depth safer rationally, to facilitate medical matters people
Member implements operation.
Wherein, protective case 1 is using having material flexible to be made, to optimize contact impression of pregnant and lying-in women's vagina with uterine neck,
Be conducive to preferably generate negative pressure wherein simultaneously, rupture of membranes operation completed, for example, the protective case 1 can be rubber protecting jacket.
Also, membrane puncture needle 2 specifically, is corresponded to, the protective case 1 also has the accommodating chamber that rear end is through to from front end,
The outer surface of the membrane puncture needle 2 is bonded with the inner surface of the accommodating chamber, in illustrated embodiment, the rear end of protective case 1 and company
The front end of socket part 3 offsets.
In addition, for the connection structure for being used to be connected to injector syringe nipple formed in the hollow cavity in rear end,
It can be set to any suitable form and size, such as can be and class in the pintle of the syringe needle of existing disposable syringe
As structure or inner surface be provided with a plurality of clamping muscle, with the nipple for being hermetically connected to existing conventional syringe,
To ultimately form the sealing communicating passage in from the front end of protective case 1 to the syringe of syringe.
Preferred embodiments of the present invention, still, the utility model and unlimited are described in detail in conjunction with attached drawing above
