Description
Technical field
The utility model relates to a kind of medical auxiliary apparatus, and in particular to a kind of pumpkin-shaped cerclage amnion feeder.
Background technique
The patient of incompetence,cervical is easy to the increase due to intrauterine pressure due to its relaxation of cervix, in second trimester, makes
It obtains uterine neck voluntarily to expand, bag of waters bulging cervical orifice, premature rupture of fetal membranes causes to miscarry.Such patient has often gone out when seeing a doctor
Existing dilatation of cervix, bag of waters bulging cervical orifice.At this point, bag of waters bulging cervical orifice, row is promptly since vagina lacuna is narrow
Lacking suitable instrument when cerclage of cervix again and lifts fetal membrane, surgical procedure is highly difficult, and it is careless slightly, it be easy to cause artificial tire
Film is early broken, leads to operative failure.Therefore, prior art active development can be used for the medical instrument of cerclage of cervix, in amnion
When capsule bulging cervical orifice, the bag of waters has been lifted upwards, and exposure uterine neck is convenient for surgical operation.Meanwhile cerclage of cervix is deposited
In risk, other than infection, it is exactly that may cause rupture of membranes there are one material risk, is especially had been expanded to quite in cervix
When big
203953773 U of CN discloses a kind of silica gel support that can be used in cerclage of cervix, specifically includes: including support
Disk, handle, the pallet use silica gel, and the handle uses hard silica gel, and the outer bottom of the pallet connects the upper end of handle,
The pallet is in the form of annular discs, and the interior disk diameter of pallet is 2-4cm, and the decreased food is 10-15cm, the inner disc surface light
It is sliding.However, the pallet of the silica gel support is sharper, rupture of membranes may cause, be easy to the fetus in the bag of waters and the bag of waters
Damage, whole device can not accurately fixed placement position, be easy to damage birth canal.
203873843 U of CN discloses Cervical cerclage assistor, including cavity, hollow ram, Y-pipe, water pocket chamber；Three
Breeches pipe, one be connect water pocket chamber drainage tube, one be water injection pipe, one be outlet pipe, outlet pipe is seal pipe, it is described in
The front end of empty push rod is provided with water pocket support, and the drainage tube passes through hollow ram, and water pocket chamber is located in water pocket support (6), described
Hollow ram pass through cavity, the water pocket support is the wing of collapsible two or two or more.Although however, the assistor
Fetus water pocket is pushed away come on using water pocket, shares the pressure of fetus water pocket, reduces the incidence of fetus water pocket rupture, but the drainage
Pipe is not fixed, and when use is inconvenient, and load-carrying construction is inadequate under water pocket, it is difficult to smoothly be realized and above be pushed away fetus water pocket.
Therefore, the prior art still lacks one kind and can prevent rupture of membranes, fixed placement position and be easy above to push away fetus
Amnion feeder.
Utility model content
The utility model aims at the problems existing in the prior art, and provides a kind of pumpkin-shaped cerclage amnion feeder,
The air bag of the flat pumpkin-shaped in concave surface can more effectively hold fetus water pocket (bag of waters of Xiang Yindao bulging), and lifting dish can provide
The biggish power of undertaking, the opening of metallic rod can fix gas-guide tube, easy to use.To achieve the above object, the utility model
Technical solution is as follows:
A kind of pumpkin-shaped cerclage amnion feeder, including sequentially connected support rod, dish and pumpkin-shaped air bag are lifted,
The support rod be it is hollow, described to lift dish the center point setting hole, the support rod is internally provided with the rubber to match
Glue gas-guide tube, rubber gas-guide tube upper end pass through the hole for lifting dish and are connected to the pumpkin-shaped air bag, and lower end passes through
The entrance of the support rod bottom is in communication with the outside, and is internally provided with the air valve of achievable inflation/deflation.
Pregnant woman's vaginal space relative narrowness, especially asian ancestry women, vaginal wall and uterine neck matter are soft, therefore, the flat pumpkin-shaped in concave surface
Air bag design can very accurate fixed placement position, and stationarity is strong.In use, the air bag connects with puerpera's birth canal
Touching, the structure of the flat pumpkin-shaped in concave surface are convenient for the bag of waters of the pop-up to vagina bulging, are more advantageous to fetal parts limbs and swollen
It is intracavitary that the bag of waters out is also contained in pregnant woman uterus from vagina；The outer rim of pumpkin-shaped can preferably fix feeder, prevent left and right inclined
It moves.Meanwhile air bag can be according to the size of the dilatation of cervical os under the clinical birth canal state of emergency, inflation at any time, which is deflated, adjusts air bag
Size, it is adaptable.
Preferably, being provided with opening on the support rod side wall, rubber gas-guide tube lower end is provided with ventilation lumen
