The auxiliary device used for cervical dilatation can limit the cervical dilatation balloon at the cervix uteri accurately, the cervical dilatation is promoted effectively, the inner opening of the cervix uteri can be expanded properly, the cervix uteri is not injured, and use is safe and convenient.
Description
Technical field
The present invention relates to medical auxiliary apparatus technical field, be specifically related to a kind of auxiliary device for cervical dilatation.
Background technology
Induced labor refers to because of mother or fetus reason, need to bring out uterine contraction, cervical dilatation by artificial method, and carcass and appurtenance thereof are discharged outside uterus and termination of pregnancy.Main induced laboring method comprises induction of labor by rivanol and induction of labor with water bag at present.Adopt induction of labor by rivanol success rate higher, safe and reliable, but the shortcoming of this method is to have minority anemia of pregnant woman to generate heat when induced labor; Another shortcoming is Hemorrhage, so that the postoperative need of most of pregnant woman induced labor are done uterine curettage.Adopt induction of labor with water bag method, to water pocket saline injection, uterus can automatically produce and shrink after the expansion of water pocket external force, and water pocket can be oppressed lower uterine segment hemostasis simultaneously, but cannot provide induced labor required cervix uteri mechanicalness expansion, and the speed of cervical dilatation determine the induced labor time.
Summary of the invention
The object of the invention is the deficiency for solving the problems of the technologies described above, a kind of auxiliary device for cervical dilatation is provided, this device can be limited to cervix uteri place accurately by cervical dilatation sacculus, effectively promote cervical dilatation, also internal cervical orifice place suitably can be expanded, and can not damage cervix uteri, safe and convenient to use.
The technical scheme that the present invention adopted is for achieving the above object: a kind of auxiliary device for cervical dilatation, the interior guiding tube and the outer guiding tube that comprise nested setting, outer guiding tube outside is provided with cervical dilatation sacculus near its head end place, by near caudal end part, be provided with the spacing sacculus of pudendum, in the tube wall of outer guiding tube, be provided with two waterflood paths, article two, waterflood path is communicated with respectively cervical dilatation sacculus and the spacing sacculus of pudendum, the tube wall of guiding tube is provided with water filling port I and the water filling port II being communicated with two waterflood paths respectively outside, described interior guiding tube outside is provided with the spacing sacculus in uterus near its head end place, the tail end of interior guiding tube is provided with the water filling port III that the waterflood path by arranging in its tube wall is communicated with the spacing sacculus in uterus, the tail end of interior guiding tube stretches out outer guiding tube and connects pull plate, and the tail end of interior guiding tube is provided with graduation mark.
The described spacing sacculus of the spacing sacculus of cervical dilatation sacculus, pudendum and uterus is made by silica gel material.
The head end of described interior guiding tube is hemispherical.
beneficial effect
The assistant apparatus structure advantages of simple of cervical dilatation provided by the invention, by the spacing sacculus of the spacing sacculus of pudendum and uterus, cervical dilatation sacculus can be limited to cervix uteri place accurately, thereby can effectively promote cervix maturation expansion, and internal cervical orifice place suitably can be expanded, improve the effect of expansion, can not damage cervix uteri, safe and convenient to use.

Labelling in figure: 1, interior guiding tube, 2, outer guiding tube, 3, cervical dilatation sacculus, 4, the spacing sacculus of pudendum, 5, water filling port I, 6, water filling port I, 7, the spacing sacculus in uterus, 8, water filling port III, 9, pull plate, 10, graduation mark.
The specific embodiment
As shown in the figure: a kind of auxiliary device for cervical dilatation, the interior guiding tube 1 and the outer guiding tube 2 that comprise nested setting, the head end of interior guiding tube 1 is hemispherical, outer guiding tube 2 outsides are provided with cervical dilatation sacculus 3 near its head end place, by near caudal end part, be provided with the spacing sacculus 4 of pudendum, in the tube wall of outer guiding tube 2, be provided with two waterflood paths, article two, waterflood path is communicated with respectively cervical dilatation sacculus 3 and the spacing sacculus 4 of pudendum, the tube wall of guiding tube 2 is provided with water filling port I 5 and the water filling port II 6 being communicated with two waterflood paths respectively outside, described interior guiding tube 1 outside is provided with the spacing sacculus 7 in uterus near its head end place, the tail end of interior guiding tube 1 is provided with the water filling port III 8 that the waterflood path by arranging in its tube wall is communicated with the spacing sacculus 7 in uterus, the tail end of interior guiding tube 1 stretches out outer guiding tube 2 and connects pull plate 9, and the tail end of interior guiding tube 1 is provided with graduation mark 10.The spacing sacculus 7 of the spacing sacculus 4 of described cervical dilatation sacculus 3, pudendum and uterus is made by silica gel material.
The using method of the auxiliary device for cervical dilatation provided by the invention is: outer guiding tube 2 is inserted in cervix uteri, control is to pudendum spacing ball capsule 4 saline injections, then promoting pull plate 9 makes interior guiding tube 1 head end from outer guiding tube 2, stretch out and enter in uterine cavity, control is spacing sacculus 7 saline injections to uterus, the pull plate 9 of slowly pulling back, according to the judgement of the graduation mark 10 of drag effect and interior guiding tube 1 tail end, make interior guiding tube 1 bounce back to the spacing sacculus 7 in uterus and be close to cervix uteri internal orifice, now control again to cervical dilatation sacculus 3 saline injections, reach the object of cervix dilating.Assistant apparatus structure advantages of simple for cervical dilatation provided by the invention, by the spacing sacculus 7 of the spacing sacculus 4 of pudendum and uterus, cervical dilatation sacculus 3 can be limited to cervix uteri place accurately, thereby can effectively promote cervix maturation expansion, and internal cervical orifice place suitably can be expanded, improve the effect of expansion, can not damage cervix uteri, safe and convenient to use.
