Abstract
A three-balloon cervical dilation balloon catheter comprises a catheter body and three balloons. A tip is formed at the front end of the catheter body, and the three balloons are arranged close to the tip of the catheter body. During use, the tip is inserted into the uterus, and the three balloons are filled with normal saline through the catheter body and used for dilating the cervix. The three balloons comprise two large balloons and a small balloon. The small balloon is clamped between the two large balloons, and the size of the small balloon is smaller than that of the large balloons. The catheter comprises the three balloons, the two large balloons are located on two sides of the internal ostium of the uterus, the small balloon is clamped between the large balloons and located at the position of the internal ostium of the uterus to dilate the cervix, the time for promoting cervical ripening is greatly reduced, and the catheter is simple in structure and convenient to use and can greatly improve the clinical efficiency.
Description
Technical field
This utility model relates to medical apparatus and instruments, relates in particular to a kind of cervical dilatation foley's tube for cervix uteri mechanical expansion.
Background technology
Clinically, often have puerpera due to self or fetus reason or pregnant 42 Zhou Erwei just before giving birth, need to impel cervix maturation by manual method, thereby carry out induced labor.
Current topmost induced laboring method has two kinds: one is pharmaceutical methods, as vagina is placed Dinoprostone and intravenous drip oxytocin; Another kind is physical method, places Foly urinary catheter or COOK impel cervix maturation sacculus etc. as cervix uteri.Because pharmaceutical methods has side effect, relatively, using balloon expandable cervix uteri is by conduit and the inside and outside two balloon pressure of cervix uteri mouth, mechanical irritation cervical canal, promote that the local endogenous prostaglandin of cervix uteri is synthetic and discharge, thereby promote uterus softening maturation, without the side effect of pharmaceutical methods, become a kind of selection preferably.But existing foley's tube is that two sacculus are expanded from cervix uteri both sides respectively, its force limited, is equivalent to be only aimed at cervix uteri both sides and carries out the expansion of mechanical force, and less for the effect of whole cervix uteri, has very large limitation.
Summary of the invention
In view of this, provide a kind of three sacculus cervical dilatation foley's tubes with larger expansionary force.
A kind of three sacculus cervical dilatation foley's tubes, comprise body and three sacculus, the front end of described body tapers off to a point, described three sacculus arrange near the tip of body, described in when use most advanced and sophisticated intron in utero, in described three sacculus by after body saline injection for cervix dilating, described three sacculus comprise two large sacculus and a little sacculus, described little sacculus is folded between two large sacculus, and the volume of little sacculus is less than the volume of described large sacculus.
Further, also comprise that the normal saline that the check (non-return) valve being contained in body prevents from injecting in described three sacculus refluxes.
Further, when use, two large sacculus lay respectively at the both sides of orificium internUm isthmi, and little sacculus is positioned at orificium internUm isthmi place, and the normal saline that large sacculus injects is no more than 80ml, and the normal saline injecting in described little sacculus is no more than 30ml.
This utility model three sacculus cervical dilatation foley's tubes have three sacculus, two large sacculus lay respectively at the both sides of orificium internUm isthmi, and being folded between large sacculus, little sacculus is positioned at orificium internUm isthmi place cervix dilating itself, so the time of cervix maturation-stimulating shortens greatly, and simple in structure, easy to use, can greatly improve clinical efficiency.
Brief description of the drawings
Fig. 1 is the structural representation of this utility model three sacculus cervical dilatation foley's tubes.
Fig. 2 is that this utility model three sacculus cervical dilatation foley's tube sacculus fill the schematic diagram after normal saline.
Fig. 3 is the using state schematic diagram of this utility model three sacculus cervical dilatation foley's tubes.
Detailed description of the invention
Below with reference to the drawings and the specific embodiments, this utility model is elaborated.
As shown in Figures 1 and 2, this utility model three sacculus cervical dilatation foley's tubes comprise 10, three sacculus of body 20,22,24, check (non-return) valve 30, and joint 40.
Described body 10 is slim-lined construction, and the front end of body 10 tapers off to a point 12, can be inserted in human body, and the tail end of body 10 is connected with described joint 40, normal saline etc. can be injected in sacculus 20,22,24 by joint 40.Described check (non-return) valve 30 is contained in body 10, to avoid injecting the medicinal liquid adverse current of sacculus 20,22,24.Described sacculus 20,22,24 arranges near the tip 12 of body 10, in the present embodiment, described sacculus 20,22,24 comprises two large sacculus 20,22 and a bead capsule 24, described bead capsule 24 is folded between described two large sacculus 20,22, and the volume of bead capsule 24 is much smaller than the volume of two large sacculus 20,22.
Please refer to Fig. 3, this utility model three sacculus cervical dilatation foley's tubes in use, the tip of body 10 12 is inserted into intrauterine, and ensure all sacculus 20, 22, 24 all pass through cervix uteri internal orifice, then to outermost, the i.e. about 40ml normal saline of the interior injection of the largest sacculus 20 at the tip 12 of close conduit, after the large sacculus 20 in outside has filled, be pulled outwardly described body 10 until the large sacculus 20 in outside approaches orificium internUm isthmi, now be positioned at inner side, away from most advanced and sophisticated 12 large sacculus 22 at orifice of uterus,external, in the large sacculus 22 of inner side, be filled with normal saline, be about equally 40ml, after completing, in bead capsule 24, be filled with about 40ml normal saline, finally respectively to all sacculus 20, 22, 24 are filled with saline, large sacculus 20, 22 inject maximum about 80ml saline, bead capsule 24 is filled with at most about 30ml saline, after completing, the tail end of body 10 being attached to puerpera's femoribus internus fixes, the longest time of inserting is no more than 12 hours, when puerpera occurs after uterine contraction reaction, can emit immediately sacculus 20, 22, saline in 24, take out this utility model three sacculus cervical dilatation foley's tubes.
This utility model three sacculus cervical dilatation foley's tubes have three sacculus 20,22,24, two large sacculus 20,22 lay respectively at the both sides of cervix uteri mouth, and being folded between large sacculus 20,22, bead capsule 24 is positioned at cervix uteri mouth place cervix dilating itself, thereby not only the expansion of mechanical force is carried out in 20,22 pairs of cervix uteri both sides of two large sacculus, bead capsule 24 has the expansion of mechanical force to cervix uteri itself simultaneously, so the time of cervix maturation-stimulating shortens greatly, and simple in structure, easy to use, can greatly improve clinical efficiency.
It should be noted that; this utility model is not limited to above-mentioned embodiment; according to creative spirit of the present utility model; those skilled in the art can also make other variations; the variation that these do according to creative spirit of the present utility model, within all should being included in this utility model scope required for protection.
