The double-cavity double-bag cervical dilatation tube is characterized in that a collateral branch tube body is arranged on the tube body and integrated with the tube body, and also provided with a communicating cavity, a communication cavity opening on the collateral branch tube body is provided with a sealing plug closing the communicating cavity, the uterine cavity cell is communicated with the injection cavity through a first communicating hole, and the uterine neck cell is communicated with the communicating cavity through a second communicating hole. The utility model has the advantages of simple structure, accurate positioning, convenience for operation, and high factor of safety, and is suitable for cervical dilatation of forcep curettage, odinopoeia and ante partum.
Description
Technical field
This utility model relates to a kind of expandable dilator, especially a kind of two capsule cervical dilatation catheters of two-chamber that are used for gravid woman's cervical dilatation.
Background technology
Cervical dilator is department of obstetrics and gynecology apparatuses commonly used, is used for cervix dilating, in being beneficial to before pregnant induced labor, the forcep curettage, prepartal cervical dilatation, guarantees carrying out smoothly of operation, reduces delivery time, alleviates puerpera's misery.A present clinical single cavity double sac cervical dilatation catheter commonly used, its uterine cavity capsule and cervix uteri capsule are to be connected with injection chamber on the body, no matter which breaks for uterine cavity capsule and cervix uteri capsule, promptly do not reach the purpose of cervix dilating, there is the low deficiency of safety factor.
Summary of the invention
In order to overcome the low deficiency of single cavity double sac cervical dilatation catheter safety factor in the prior art, this utility model provides a kind of two-chamber two capsule cervical dilatation catheters, and the two capsule cervical dilatation catheters of this two-chamber are not only simple in structure, reasonable in design, and accurate positioning, vi have high safety.
The technical scheme that its technical problem that solves this utility model adopts is: the two capsule cervical dilatation catheters of a kind of two-chamber, it comprises that one has the body that injects the chamber, the one end sealing of this body, the other end is provided with the accent that injects the chamber, end in the body sealing is provided with an expandable uterine cavity capsule and an expandable cervix uteri capsule successively, injection accent place on body is provided with the sealing-plug that the chamber is injected in a sealing, it is characterized in that: on described body, be integrally formed with Zhi Guanti on one side with it, this collateral branch's body is provided with a connected chamber, connection accent place on collateral branch's body is provided with the sealing-plug of a sealing connected chamber, described uterine cavity capsule is connected with described injection chamber through first intercommunicating pore, and described cervix uteri capsule is connected with connected chamber through second intercommunicating pore.
Described uterine cavity capsule, its utricule is a shape of falling the calabash.
Described cervix uteri capsule, its utricule is provided with annular protrusion.
Described collateral branch body, it is close in the cervix uteri capsule on the body.
Play fixation after the uterine cavity capsule of the present utility model water filling, cylindrical after the water filling of cervix uteri capsule, there are a plurality of annular protrusions on the surface, more can stimulate cervical canal effectively, promotes cervical dilatation.The cervix uteri capsule that collateral branch's body is close on the body can play localized effect, prevents to insert in the operation dark.This utility model is simple in structure, and accurate positioning is easy and simple to handle, vi have high safety, in being applicable to pregnant pincers scrape, induced labor, prepartal cervical dilatation.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing
Accompanying drawing is a kind of structure master's cutaway view of the present utility model
Among the figure: 1. sealing-plug, 2. inject the chamber, 3. body, 4. cervix uteri capsule, 401. annular protrusions, 5. first intercommunicating pore, 6. uterine cavity capsule, 7. sealing-plug, 8. collateral branch's body, 9. connected chamber, 10. second intercommunicating pore.
The specific embodiment
In the accompanying drawings, the two capsule cervical dilatation catheters of a kind of two-chamber, it comprises a body 3, is provided with one and injects chamber 2 on body 3.The one end sealing of body 3, the other end is provided with the accent that injects chamber 2, is provided with the sealing-plug 1 that the chamber is injected in a sealing on this injection accent.Sealing plug 1 can prevent to inject the leaked liquid in the chamber 2.
End in body 3 sealings is provided with an expandable uterine cavity capsule 6 and an expandable cervix uteri capsule 4 successively.Wherein the utricule of uterine cavity capsule is a shape of falling the calabash.The utricule of cervix uteri capsule is provided with annular protrusion 401.
Be provided with Zhi Guanti 8 on one side on body 3, collateral branch's body 8 is close in the cervix uteri capsule 4 on the body 3, and designs with body 3 one, utilizes its ramose structure can play localized effect to convergent divergent channel.
Be provided with a connected chamber 9 on collateral branch's body 8, the connection accent place on collateral branch's body is provided with the sealing-plug 7 of a sealing connected chamber 9.
As shown in the drawing, uterine cavity capsule 6 is connected with injection chamber 2 through first intercommunicating pore 5; Cervix uteri capsule 4 is connected with connected chamber 9 through second intercommunicating pore 10.
When this utility model uses, it is sent into the uterus earlier, adopt syringe to extract physiological saline solution 100ml then, syringe puncture seal plug 1 injects normal saline in the uterine cavity capsule 6 through injecting chamber 2, makes 6 expansions of uterine cavity capsule and plays fixation in uterus; Utilize syringe to extract sterile water for injection 50-60ml again, syringe puncture seal plug 7 injects cervix uteri capsule 4 with normal saline through connected chamber 9, expands after 4 water fillings of cervix uteri capsule, annular protrusion on its utricule, can more effectively stimulate cervix uteri, promote cervical dilatation, reduce expansion time and patient suffering.Operation finishes the back extracts cervix uteri capsule 4, uterine cavity capsule 6 physiological saline solution out respectively with syringe, can take out the two capsule cervical dilatation catheters of this two-chamber.
In a single day cervix uteri capsule 4 of the present utility model breaks, and uterine cavity capsule 6 moves down under the effect of gravity gradually, and it is down lageniform utricule and helps it and enter and continue cervix dilating in the cervical canal, can play the dual fail-safe effect.
