Abstract
The utility model discloses a sacculus posture cervical extension fixture, including the pipe, the pipe front portion sets gradually two sacculuss, and the anterior end of pipe sets up the end cap, at the rear end of pipe two branch pipes that set up that one is long and the other is short, all is provided with the check valve on two branch pipes, the terminal syringe interface that is of check valve. The utility model discloses it is rational in infrastructure, safe and reliable, carry out the machinery expansion of cervical pipe to the not good cervical of maturity before being applicable to mature induced labor.
Description
Technical field
This utility model relates to a kind of balloon uterine cervix expansion device.
Background technology
The neonate of the annual birth in the whole world, gestation is completed by induced labor, and induced labor success is relevant with various factors, and wherein cervical ripeness has been conclusive key factor.
The mechanicalness of eutocous initial cause of labor is theoretical: be in progress with gestation, uterine volume, stretching force and tension force constantly increase, in utero pressure increases, uterine muscular and the obvious pressurized of decidua; the mechanoreceptor of flesh wall is received and stimulated, and especially the mechanism of expansion occurs cervix uteri, reaches hypothalamus by sympathetic nerve; make neurohypophysis discharge oxytocin, cause uterine contraction.Primipara first occurs that the infundibulate of cervix uteri internal orifice changes, and cervical canal shortens, and then occurs the expansion of cervical orifice; In multipara's cervix uteri, collar extension expansion and cervical canal shortening are carried out simultaneously.
Cervical canal also not good to Maturity in prior art carries out the device of mechanical expansion.
Summary of the invention
The purpose of this utility model is to provide a kind of rational in infrastructure, safe and reliable balloon uterine cervix expansion device.
Technical solution of the present utility model is:
A kind of balloon uterine cervix expansion device, it is characterized in that: comprise conduit, conduit front portion sets gradually two sacculus, conduit forward terminal arranges plug, arrange in the rear end of conduit one is long and the other is short two arms, two arms are provided with check valve, and check valve end is syringe interface.
Described conduit is double walled double-layer tube.
The syringe interface of check valve end mates with standard syringe.
This utility model has the advantages such as structure is simple, accurate positioning, use safety.Along with the prolongation of indwelling time, cervix uteri is little by little expanded naturally.All the time gentle tension force---cervix uteri internal orifice and collar extension is provided in cervix uteri level; Without the side effect that medicinal application causes.Before being applicable to term induced labor, the cervix uteri not good to Maturity carries out the mechanical expansion of cervical canal.
The mechanism of action: bilateral sacculus provides gentle stable mechanical force cervix dilating, and distal balloon catheter is pressed close to cervix uteri internal orifice and caused decidua to be separated, and stimulation of endogenous prostaglandin excretion, finally brings out uterine contraction.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is the structural representation of this utility model embodiment.
Detailed description of the invention
A kind of balloon uterine cervix expansion device, comprise conduit 4, conduit front portion sets gradually two sacculus 2,3, and conduit forward terminal arranges plug 1, different being used for of one is long and the other is short two arms 5, two length of tube is set in the rear end of conduit and distinguishes the order injecting sacculus liquid; Two arms are provided with check valve 6 and mark 7, check valve end is syringe interface.
Described conduit is double walled double-layer tube.The syringe interface of check valve end mates with standard syringe.
Double-walled conduit adopts environmental protection macromolecule material (TPE, TPU, TPEE, TPV etc.) to make.Sacculus 2,3 is macromolecular elastomer material, and saline injection can swell and contraction, and inflation volume is relevant to the injection salt water yield.Two arms 5 adopt environmental protection macromolecule material (TPE, TPU, TPEE, TPV etc.) to make; Check valve 6 adopts macromolecular material (PC, PET or nylon) injection moulding, is unidirectional entering during saline injection.
When this utility model uses, first insert vaginal speculum, by guiding tube, uterine cervix expansion device is inserted vagina and cervix uteri, until two sacculus all enter cervical canal.Inject 40ml normal saline by standard syringe by the check valve on an arm and make sacculus 2 swell.Once after uterus sacculus 2 swell, apparatus of pulling back is until sacculus 2 touch cervical canal internal orifice.
Inject 20ml normal saline by standard syringe by the check valve on another arm and make sacculus 3 swell.Two sacculus lay respectively at cervix uteri both sides, and such apparatus is just secured in place.
This utility model has the advantages such as structure is simple, accurate positioning, use safety.Along with the prolongation of indwelling time, cervix uteri is little by little expanded naturally.All the time gentle tension force---cervix uteri internal orifice and collar extension is provided in cervix uteri level; Without the side effect that medicinal application causes.
