Abstract
The utility model relates to a cervical dilator, which belongs to the field of medical appliances. The cervical dilator comprises a base, a guide tube, a cervix dilating air sac, metal signs, a vagina positioning air sac, an air cavity, an air valve and an inflating ball, wherein the front end of the guide tube is respectively provided with the cervix dilating air sac and the vagina positioning air sac; the back end of the guide tube is provided with the base; and the periphery of the base is provided with the inflating ball. The guide tube is divided into a main cavity and a sub cavity; the main cavity is a communicated cavity; the sub cavity is an air cavity; and the air cavity is communicated with the inflating ball, the cervix dilating air sac and the vagina positioning air sac. One end of the air cavity adjacent to the inflating ball is provided with the air valve; both of the cervix dilating air sac and the vagina positioning air sac have double layers; the inner layer is a glue layer and the outer layer is a fiber layer; and both ends of the cervix dilating air sac are respectively provided with the metal signs, and the position of the air sac can be displayed through the metal signs in x rays, so the air sac can be accurately and conveniently positioned. The utility model has the advantages of reasonable structure, accurate positioning, safe use and the like.
Description
Technical field
This utility model relates to technical field of medical instruments, especially a kind of cervical dilator.
Background technology
In clinical, treatment hysteropathy or when artificially inducing abortion, often will carry out the expansion of cervix uteri, the cervix dilator of now having announced is of a great variety, and the inflated type cervix dilator is arranged, the water pocket cervix dilator is also arranged, though different characteristics is all arranged separately, the expansion of cervix uteri is also had certain effect, also there is following defective in comprehensive the measurement, the one, operating difficulties is located inaccurate; The 2nd, not obvious to the expansion effect of cervix uteri.
Summary of the invention
This utility model is at the deficiencies in the prior art, and a kind of accurate positioning, cervical dilator easy and simple to handle, safe in utilization are provided.
This utility model is achieved through the following technical solutions:
The cervical dilator that this utility model provides includes pedestal, guiding tube, cervical dilatation air bag, metal flag, vagina positioning gasbag, air cavity, air valve, inflatable ball composition.The guiding tube front end is established cervical dilatation air bag, vagina positioning gasbag successively, and pedestal is established in the rear end, is provided with inflatable ball near the pedestal.
Described guiding tube is divided into main chamber and secondary chamber, main chamber is for connecting the chamber, be used to reduce the intrinsic pressure of uterine cavity, secondary chamber is an air cavity, air cavity connection inflatable ball and cervical dilatation air bag, vagina positioning gasbag, air cavity is equipped with air-filled pore in two air bags, air cavity is established air valve near inflatable ball one end, and inflatable ball and air valve all adopt rubber bulb (being commonly called as foot blower) and the air valve that uses on the sphygomanometer.
Described cervical dilatation air bag, vagina positioning gasbag are bilayer, internal layer is a glue-line, skin is a fibrous layer, the air bag internal layer expands when guaranteeing airbag aeration, and outer layer fiber layer restriction air bag can infinitely not expand, simultaneously because fiber layer surface is coarse relatively, be convenient to the location of air bag in cervix uteri and vagina, the cervical dilatation balloon ends is established metal flag respectively, can show the position of air bag under x light, is convenient to accurate location.
When this utility model uses, by guiding tube cervical dilator is inserted vagina and cervix uteri, under the supervision of x line, make the cervical dilatation air bag just be in position of uterine neck, expand to airbag aeration, the cervical dilatation air bag carries out the compression type expansion to cervix uteri, and the vagina positioning gasbag plays certain positioning action.
The utlity model has rational in infrastructure, accurate positioning, advantage such as safe in utilization.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Wherein: 1, pedestal 2, guiding tube 3, cervical dilatation air bag 4, metal flag 5, vagina positioning gasbag 6, air cavity 7, air valve 8, inflatable ball
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples, and cervical dilator includes pedestal 1, guiding tube 2, cervical dilatation air bag 3, metal flag 4, vagina positioning gasbag 5, air cavity 6, air valve 7, inflatable ball 8 compositions.Guiding tube 2 front ends are established cervical dilatation air bag 3, vagina positioning gasbag 5 successively, and pedestal 1 is established in the rear end, are provided with inflatable ball 8 nearby apart from pedestal 1.Guiding tube 2 is divided into main chamber and secondary chamber, and main chamber is for connecting the chamber, and secondary chamber is an air cavity 6, air cavity 6 connection inflatable ball 8 and cervical dilatation air bag 3, vagina positioning gasbag 5, and air cavity 6 is equipped with air-filled pore in two air bags, and air cavity 6 is established air valve 7 near inflatable ball one ends.Cervical dilatation air bag 3, vagina positioning gasbag 5 are bilayer, and internal layer is a glue-line, and skin is a fibrous layer, and metal flag 4 is established at cervical dilatation air bag 3 two ends respectively, can show the position of air bag under x light, are convenient to accurate location.
