Abstract
An amniotic membrane pushing-in device for the cerclage comprises a pipe body with the top end provided with a supporting bag. The supporting bag is connected with an injection connector outside the tail end of the pipe body through an infusion pipe inside the pipe body. The supporting bag is in a bowl shape after being filled with liquid. The diameter of the pipe body is 2 cm, and the length of the pipe body ranges from 20 cm to 25 cm. After being filled with water, the supporting bag becomes a bowl-shaped silicon rubber bag with the diameter being 4 cm and the height being 1.5 cm. The injection connector is provided with a shutoff valve. The amniotic membrane pushing-in device is simple in structure, convenient to operate, good in using effect and low in cost. By means of the amniotic membrane pushing-in device, the hurt to the foetal membrane and the possibility of foetal membrane rupture in the cerclage process are avoided, and a protruding amniotic membrane bag can be put back into the uterine cavity through the bowl-shaped supporting bag; after the cervix uterus is sutured, knotting is carried out on the amniotic membrane bag, the amniotic membrane bag cannot protrude any more, the foetal membrane can be protected against hurt, and labor is saved.
Description
Technical field
This utility model relates to a kind of medical auxiliary apparatus, is specifically related to a kind of cerclage amniotic membrane feeder.
Background technology
Incompetence,cervical also claims internal cervical orifice inadequacy, cervical orifice laxity.Incompetence,cervical patient's cervix uteri fibre-bearing tissue, elastic fiber and smooth muscle etc. are all less, or due to the fracture of cervix uteri internal orifice fibrous tissue, isthmus sphincter ability reduces, and make cervix uteri be pathologic expansion and lax.The performance of cervical incompetence cervical incompetence be mainly premature labor and in, late period Recurrent spontaneous abortion, habitual abortion person's incidence rate is 8%～15%.Second trimester or occur the Silent Neuritis expansion of cervix uteri pregnant late period, enters vagina with gestation sac swollen, can see shortening or the funnel (fetal membrane is funnel-form and enters cervix uteri internal orifice) of cervix uteri internal orifice under B ultrasonic.Cause subsequently giving birth to of premature rupture of fetal membrane and immature fetus.Unless take effective treatment, otherwise each this process of gestation all can repeat to occur.
When trimester of pregnancy carries out cerclage does not have unified final conclusion at present.Gestation month is more late, and operation causes the probability of miscarriage and premature rupture of fetal membrane just larger.Prophylactic cervical cerclage art was generally carried out at pregnant 14 weeks-16 weeks.When cervical dilatation and effacement of cervix have occurred pregnant middle and advanced stage, implement cerclage and be called as " emergency case " cerclage or " remedying " property cerclage to stop to further develop.Now how amniotic sac has charged into intravaginal; when annular interrupted suture cervix uteri; there is assistant with gauze or cotton balls; outstanding amniotic sac is protected; sew up back the amniotic sac taking off into vagina is returned to uterine cavity; limit knotting, causes the probability of rupture of membranes greatly to increase in art, the probability of operative failure is high.
Summary of the invention
The purpose of this utility model is to provide a kind of cerclage amniotic membrane feeder, to overcome the deficiencies in the prior art.
A cerclage amniotic membrane feeder, is characterized in that comprising that a top is provided with the body of holder capsule, and this holder capsule is connected with the injection joint outside body end via the tube for transfusion in body, after described holder capsule is full of liquid, is bowl-type.
The diameter of above-mentioned body is 2CM, and length is 20CM-25CM.
After the water filling of above-mentioned holder capsule, be diameter 4CM, height is 1.5CM bowl type silicon capsule.
Above-mentioned injection joint is provided with shut off valve.
The utility model has the advantage of: simple in structure, easy to operate, result of use is good; with low cost; while having solved cerclage, the damage to fetal membrane, has avoided the probability of rupture of membranes; the design of bowl-type holder capsule is convenient to outstanding amniotic sac also to receive the chamber of being put in prison; after cervix uteri ties, tie a knot and can again not give prominence to amniotic sac, withdraw from this device; so not only can protect fetal membrane injury-free, and save manpower.
Accompanying drawing explanation
Population structure schematic diagram when Fig. 1 is this utility model use.
Wherein, 1, body, 2, holder capsule, 3, tube for transfusion, 4, injection joint, 5, shut off valve.
The specific embodiment
As shown in Figure 1, a kind of cerclage amniotic membrane feeder, is characterized in that comprising that a top is provided with the body 1 of holder capsule 2, and this holder capsule 2 is connected with the injection joint 4 outside body 1 end via the tube for transfusion 3 in body 1, after described holder capsule 2 is full of liquid, is bowl-type.
Consider that vaginal orifice is to the distance of cervix uteri mouth, the diameter of above-mentioned body 1 is 2CM, and length is 20CM-25CM.
Considering the size of fetal membrane capsule, is diameter 4CM-5CM after above-mentioned holder capsule 2 water fillings, and height is 1.5CM bowl type silicon capsule.
Consider convenient control, above-mentioned injection joint 4 is provided with shut off valve 5.
While using this utility model, first body 1 is inserted to intravaginal, make body 1 and amniotic sac keep certain distance, before use, first with syringe, connect injection joint 4 and to the interior water filling of holder capsule 2, make its expansion by tube for transfusion 3, form bowl type silicon capsule, put it into vagina, hold the amniotic sac taking off into vagina, by promoting body 1, drive holder capsule 2 to make amniotic sac slowly also receive the chamber of being put in prison, final holder capsule 2 is got back to intrauterine together with amniotic sac, after cervix uteri ties, tie a knot to amniotic sac and can again not give prominence to, shut off valve 5 on injection joint 4 is opened, make to hold in the palm the water in capsule 2 to flow out, holder capsule 2 becomes flat thereupon, extract out together with body 1.The utility model has the advantage of: simple in structure; easy to operate, result of use is good, with low cost; while having solved cerclage; damage to fetal membrane, has avoided the probability of rupture of membranes, the design of bowl-type holder capsule to be convenient to outstanding amniotic sac also to receive the chamber of being put in prison; after cervix uteri ties; tie a knot and can again not give prominence to amniotic sac, so not only can protect fetal membrane injury-free, and save manpower.
