Abstract
The invention relates to an auxiliary uterine cervix dilation device. The auxiliary uterine cervix dilation device comprises an inner guiding catheter and an outer guiding catheter. A cervix dilation balloon is arranged at the head end of the outer guiding catheter, a vulva limiting balloon is arranged close to the tail end of the outer guiding catheter, two water injection channels are arranged in the wall of the outer guiding catheter and communicated with the cervix dilation balloon and the vulva limiting balloon respectively, and a water injection port I and a water injection port II which are communicated with the two water injection channels are formed in the wall of the outer guiding catheter. A uterus limiting balloon is arranged at the position, close to the head end of the inner guiding catheter, of the outer side of the inner guiding catheter, a water injection port III is formed in the tail end of the inner guiding catheter, the tail end of the inner guiding catheter stretches out of the outer guiding catheter and is connected with a baffle, and the tail end of the inner guiding catheter is sleeved with a compression spring used for pushing the inner guiding catheter backwards. The auxiliary uterine cervix dilation device can effectively facilitate ripening and dilating of the cervix and cannot injure the cervix, the cervix dilation balloon can be accurately limited at the cervix through the vulva limiting balloon and the uterus limiting balloon, the dilation effect is enhanced, and the auxiliary uterine cervix dilation device is safe and convenient to use.
Description
Technical field
The present invention relates to medical auxiliary apparatus technical field, be specifically related to a kind of cervix uteri auxiliary expanding equipment.
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 in the time of induced labor; Another shortcoming is Hemorrhage, so that the postoperative need of most of pregnant woman induced labor do 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 cervix uteri auxiliary expanding equipment 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 cervix uteri auxiliary expanding equipment, comprise interior guiding tube and the outer guiding tube of nested setting, outer guiding tube outside is provided with cervical dilatation sacculus near its head end place, be provided with the spacing sacculus of pudendum by near caudal end part, 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 the water filling port I and the water filling port II that are 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 baffle plate, and the tail end of interior guiding tube is arranged with for the Compress Spring to pusher by interior guiding tube, the two ends of spring are fixedly connected with baffle plate with outer guiding tube respectively.
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
Cervix uteri auxiliary expanding equipment provided by the invention is simple and reasonable, 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.

Detailed description of the invention
As shown in the figure: a kind of cervix uteri auxiliary expanding equipment, comprise interior guiding tube 1 and the outer guiding tube 2 of 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, be provided with the spacing sacculus 4 of pudendum by near caudal end part, 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 the water filling port I 5 and the water filling port II 6 that are 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 baffle plate 9, and the tail end of interior guiding tube 1 is arranged with for the Compress Spring 10 to pusher by interior guiding tube 1, the two ends of spring 10 are fixedly connected with baffle plate 9 with outer guiding tube 2 respectively.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 cervix uteri auxiliary expanding equipment of the present invention is: outer guiding tube 2 is inserted in uterine cavity, control to pudendum spacing ball capsule 4 saline injections, then promote baffle plate 9 stretches out interior guiding tube 1 head end from outer guiding tube 2, control to uterus spacing sacculus 7 saline injections, slowly decontrol baffle plate 9, under the effect of spring 10, interior guiding tube 1 can bounce back, until the spacing sacculus 4 of pudendum is close to cervix uteri collar extension, the spacing sacculus 7 in uterus is close to cervix uteri internal orifice, now control again to cervical dilatation sacculus 3 saline injections, reach the object of cervix dilating.Cervix uteri auxiliary expanding equipment provided by the invention is simple and reasonable, 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.
