Abstract
The utility model discloses a cervical dilator, comprising a hard conduit (1) and an air bag arranged in front of the conduit (1), wherein the front end of the conduit (1) is sealed, and the side wall is provided with a hole (3) which is communicated with the air bag, and the back end of the conduit (1) is provided with an air-filling port (4). The utility model has the advantages of simple operation and little stimulation to the patients.
Description
Technical field
This utility model relates to a kind of gynecologic operating instruments, particularly a kind of cervical dilator.
Background technology
Artificial abortion need be to cervical dilatation, and prior art cervical dilatation apparatus mostly is the expansion metal rod, and the stimulation to the patient during use is bigger, particularly knockdown expansion metal rod needs conversion repeatedly to insert, cause the cervix uteri damage easily, troublesome poeration, the patient suffering is big.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned shortcoming, provide a kind of easy and simple to handle, the patient is stimulated little cervical dilator.
This utility model is achieved in that a kind of cervical dilator, comprises hard conduit and places the forward air bag of conduit, and the catheter proximal end sealing, side-wall hole is communicated with air bag, and the rear end is provided with the inflation interface.
As further improvement of the utility model, this inflation seam is provided with breather cheek valve, and catheter proximal end is the round sealed head.
This utility model utilizes catheter directed insertion, and is easy and simple to handle by airbag aeration cervix dilating gradually, and expansionary force is even simultaneously, cervix uteri stimulated little, damages for a short time, and the patient suffering is little.
Description of drawings
Accompanying drawing is a sectional structure sketch map of the present utility model.
Among the figure: 1, conduit, 2, air bag, 3, the hole, 4, the inflation interface, 5, breather cheek valve.
The specific embodiment
Make this utility model with reference to accompanying drawing, this utility model conduit 1 can adopt diameter to make less than three millimeters stereoplasm tube, mainly plays guiding and gas pipeline effect.The front end of conduit 1 can reduce the insertion resistance for the round end of sealing, and the side-wall hole 3 of conduit 1 and is arranged on conduit 1 forward air bag 2 and is communicated with.Conduit 1 rear end connects to be provided with inflates interface 4, and inflation interface 4 places are provided with breather cheek valve 5.
During use, utilize conduit 1 guiding air bag 2 to insert the cervix uteri mouth, connect aerating device by inflation interface 4, to air bag 2 inflations, air bag 2 is evenly expanded, and reaches the cervix dilating purpose.
