Abstract
This utility model relates to a kind of obstetrics cervix dilatation device, there is the ringent reaming cylindrical shell in loudspeaker, the edge of one end that reaming cylindrical shell upper shed diameter is less flips to the outside and bends and looping draw-in groove, annular slot is provided with bellows, elastic tape is provided with in one end of bellows, the valve inside mouth be connected with external air pump is installed by O-ring seal in outer field one end of bellows, one end of spacing body is inserted in bellows, the other end is half cone-shaped structure and snaps in the less one end of reaming cylindrical shell upper shed diameter.This utility model uses for reference the telescopic structure of corrugated tube, being filled with by gas, bellows is extended and becomes through state, play the effect of expansion, there is certain flexibility, avoid the pain that simple and crude stretching pliers causes, simultaneously due to the existence of bellows, operating theater instruments can be avoided to touch non-surgical, can superinfection be avoided, safe and reliable, have practical value.
Description
Technical field
This utility model relates to a kind of obstetrics cervix dilatation device.
Background technology
In known technical field, artificial abortion is artificial abortion, is deliberately terminate gestation, takes out embryo or causes the behavior of foetal death.Before the surgery, regular hospital should carry out preoperative planning to anemia of pregnant woman, as comprised routine blood test, urine examination, B ultrasonic, electrocardiogram, leucorrhea routine etc., check knownly whether suffer from systemic disease by these, whether be ectopic pregnancy, with or without gynecological inflammation, and accurately can judge pregnant capsule size and position etc., increase the safety of operation.In the carrying out of operation, generally need the expansion carrying out vagina, cervix uteri mouth with cervix dilatation device, so that the intervention of apparatus, the general expansion cylinder of stretching pliers or tubular of using directly inserts, in the operation of reality, because the sign of individual patient is different, the mode of stretching pliers or expansion cylinder is adopted to seem comparatively rough, also easily cause pain, in the process of apparatus intervention, apparatus can touch the sidewall of cervix uteri, vagina simultaneously, easily causes superinfection.
Utility model content
The technical problems to be solved in the utility model is: overcome the problems referred to above, provides a kind of adaptable, obstetrics' cervix dilatation device that is low, that not easily cause superinfection of keenly feeling.
This utility model solves the technical scheme that its technical problem adopts: a kind of obstetrics cervix dilatation device, there is the ringent reaming cylindrical shell in loudspeaker, the edge of one end that described reaming cylindrical shell upper shed diameter is less flips to the outside and bends and looping draw-in groove, described annular slot is provided with bellows, elastic tape is provided with in one end of described bellows, and described elastic tape hoop is in annular slot, in the tube wall of described bellows has, two-layer outward, and the valve inside mouth be connected with external air pump is installed by O-ring seal in outer field one end of bellows, spacing body is provided with between described reaming cylindrical shell and bellows, one end of described spacing body is inserted in bellows, the other end is half cone-shaped structure and snaps in the less one end of reaming cylindrical shell upper shed diameter.
The beneficial effects of the utility model are: this utility model structure is simple, reasonable in design, use for reference the telescopic structure of corrugated tube, being filled with by gas, bellows is extended and becomes through state, play the effect of expansion, there is certain flexibility, avoid the pain that simple and crude stretching pliers causes, simultaneously due to the existence of bellows, operating theater instruments can be avoided to touch non-surgical, can superinfection be avoided, safe and reliable, have practical value.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, this utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the partial enlargement structural representation at A place in Fig. 1;
In figure: 1. reaming cylindrical shell, 2. annular slot, 3. bellows, 4. elastic tape, 5. O-ring seal, 6. valve inside mouth, 7. spacing body.
Detailed description of the invention
By reference to the accompanying drawings this utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with this utility model.
The preferred embodiment of this utility model obstetrics cervix dilatation device as depicted in figs. 1 and 2, there is the ringent reaming cylindrical shell 1 in loudspeaker, the edge of one end that described reaming cylindrical shell 1 upper shed diameter is less flips to the outside and bends and looping draw-in groove 2, annular slot 2 is provided with bellows 3, elastic tape 4 is provided with in one end of bellows 3, and elastic tape 4 binds round in annular slot 2, in the tube wall of described bellows 3 has, two-layer outward, and the valve inside mouth 6 be connected with external air pump is installed by O-ring seal 5 in outer field one end of bellows 3, spacing body 7 is provided with between reaming cylindrical shell 1 and bellows 3, one end of described spacing body 7 is inserted in bellows 3, the other end is half cone-shaped structure and snaps in the less one end of reaming cylindrical shell 1 upper shed diameter.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content in description, must determine its technical scope according to right.
