Abstract
The utility model relates to a double-sac cervix expanding duct, comprising a duct body with an injection cavity. The double-bag cervix expanding duct is characterized in that the closed top end of the duct body is sequentially provided with an expandable uterine cavity sac and at least one expandable cervix sac, one side of the duct body, which is close to the cervix sac, is provided with a butterfly-shaped baffle which is integrally arranged with the duct body, a seal plug for closing the injection cavity is arranged at the opening of injection cavity at the tail end of the duct body, and the uterine cavity sac and the cervix sac are respectively communicated with the injection cavity through communication holes. The utility model has the advantages of reasonable design, novel conception, accurate positioning, simple and convenient operation and suitability for cervix expansion before abortion, odinopoeia and parturition.
Description
Technical field
This utility model relates to a kind of expandable dilator, especially a kind of two capsule cervical dilatation catheters 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, is beneficial to miscarry, the carrying out smoothly of operations such as induced labor, childbirth.The method of clinical cervix dilating commonly used has at present: the one, adopt expansion metal rod cervix dilating, and it is big to there is mechanical stimulus, the painful big deficiency of patient; The 2nd, adopt the dilatation of ureter cervix uteri, the degree of depth that there is insertion is difficult for grasping, and pulls and pushes easy infection, easily slippage repeatedly; The 3rd, adopt medicine Radix Achyranthis Bidentatae, Sargassum rod cervix dilating, there is the deficiency of medicine source anxiety.
Summary of the invention
Big in order to overcome in the prior art mechanical stimulus, easy infection, inaccurate deficiency is located in easily slippage, and this utility model provides a kind of pair of capsule cervical dilatation catheter, and this pair capsule cervical dilatation catheter is simple in structure, and accurate positioning is fixed, is difficult for slippage, and is easy and simple to handle.
The technical scheme that its technical problem that solves this utility model adopts is: a kind of pair of capsule cervical dilatation catheter, it comprises that one has the body that injects the chamber, it is characterized in that: the top in this body sealing is provided with an expandable uterine cavity capsule and at least one expandable cervix uteri capsule successively, on the body that closes on cervix uteri capsule one side, be provided with a butterfly block that is wholely set with body, be provided with the sealing-plug that the chamber is injected in a sealing at the injection accent place of described body end, described uterine cavity capsule, cervix uteri capsule are connected with described injection chamber through intercommunicating pore respectively.
It is 3 that the described capsule of uterine cavity successively is arranged on the vertical inflatable cervix uteri capsule of body.
This utility model is successively set on the vertical uterine cavity capsule of body and at least one cervix uteri capsule, and after full normal saline expanded, liquid can circulate mutually in it, massage cervical canal and lower uterine segment better, and the uterine cavity capsule is positioned at the cervix uteri top, plays fixation, is difficult for deviating from; After its cervix uteri capsule expanded, the cervix uteri capsule was splayed at interval, and the capsule ectosome is similar cylindrical, can adapt to the anatomical structure of cervix uteri tube chamber better.The butterfly block that it closes on the body of cervix uteri capsule one side can effectively prevent to insert in the operation dark, and turnover repeatedly reduces infection.This utility model design is ingenious, novel, and accurate positioning is easy and simple to handle, is applicable to miscarriage, induced labor, prepartal cervical dilatation.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is this utility model master cutaway view.
Fig. 2 is the cutaway view of A-A line among Fig. 1.
Among the figure: 1. sealing-plug, 2. inject chamber, 3. body, 4. butterfly block, 5. cervix uteri capsule, 6. intercommunicating pore, 7. uterine cavity capsule.
The specific embodiment
In Fig. 1, a kind of pair of capsule cervical dilatation catheter, it comprises a body 3, on this body 3, is provided with one and injects chamber 2, the end sealing of body 3, the other end is provided with the sealing-plug 1 that the chamber is injected in a sealing for injecting the accent in chamber on this injection accent.Sealing plug 1 can prevent to inject the leaked liquid in the chamber 2.
As shown in Figure 1, be provided with an expandable uterine cavity capsule 7 and 3 expandable cervix uteri capsules 5 successively on the top of body 3 sealings.
Among Fig. 1, Fig. 2, be provided with a butterfly block 4 on the body 3 that closes on cervix uteri capsule 5 one sides, this butterfly block 4 is wholely set with body 3.Butterfly block 4 can effectively prevent to insert in the operation dark, and turnover repeatedly reduces and infects, and also can prevent to puncture amniotic sac, causes premature rupture of fetal membrane,
As shown in Figure 1, uterine cavity capsule 7, cervix uteri capsule 5 are connected with injection chamber 2 through intercommunicating pore 6 respectively.
During use, the two capsule cervical dilatation catheters of this utility model are sent into the uterus, extract physiological saline solution 150ml, syringe puncture seal plug 1 with syringe, normal saline is injected respectively in cervix uteri capsule 5, the uterine cavity capsule 7 through injecting chamber 2, make cervix uteri capsule 5, uterine cavity capsule 7 fill normal saline and expand.Wherein uterine cavity capsule 7 is positioned at the cervix uteri top, plays fixation, is difficult for deviating from.After cervix uteri capsule 5 expanded, interval each other was splayed, and its ectosome is similar cylindrical, can adapt to the anatomical structure of cervix uteri tube chamber better.In addition, uterine cavity capsule 7 can circulate mutually with cervix uteri capsule 5 interior liquid, massages cervical canal and lower uterine segment better.Operation finishes the back extracts physiological saline solution out with syringe, can take out this pair capsule cervical dilatation catheter.
Claims (2)
