Abstract
The utility model relates to a cervical dilatation sacculus pipe, the utility model discloses a keep somewhere the two sacculus pipes of silica gel system in departments such as palace opening inner edge, including the sacculus of two kinds of sizes in the structure, in two sacculus take out all arrange the cervix in after air and water during the use, the inflation of sacculus injected water, the produced mechanical stimulation of inflation through each sacculus induces the uterine contraction, makes the baby more conveniently pass through the cervical orifice smoothly to reach the purpose of delivering smoothly.
Description
Technical Field
The utility model relates to the field of medical equipment, especially, relate to a cervical dilatation sacculus pipe.
Background
The cervical opening is softened by the expansion and friction of the two water bags of the cervical dilatation balloon, so that the cervical opening is opened, and the cervical dilatation balloon is a common means for opening the cervical opening in the current hospital during the spontaneous labor delivery. The structure of the cervical dilatation balloon is that two water sacs are consistent in size, one water sac is arranged in the cervix, the other water sac is arranged outside the cervix, and the cervical orifice is softened and opened by the friction of the two balloons and the action of gravity. However, after the cervical dilatation balloon softens the cervical orifice and opens the cervical orifice by 1.5cm, the balloon is separated from the birth canal, the subsequent labor process is not affected any more, and the ideal effect of the puerpera in the later period of childbirth is still not achieved.
SUMMERY OF THE UTILITY MODEL
The utility model overcomes foretell weak point, aim at provides a cervical dilatation sacculus pipe, the utility model discloses a two sacculus are all kept somewhere in the cervix uteri and are filled the head and keep somewhere the two sacculus pipes of silica gel system outside birth canal, including two big or small sacculus in the structure, all arrange in the cervix uteri after taking out air and water in two sacculus during the use, sacculus injected water inflation, the produced mechanical stimulation of inflation through each sacculus induces the uterine contraction, make baby's head hug closely big sacculus front end concave part, baby's head, big sacculus, the whole toper shape that is of sacculus, make things convenient for the baby to pass through the cervix uteri mouth smoothly, thereby reach smooth childbirth, improve the purpose of the rate of birth of following birth.
The utility model discloses a reach above-mentioned purpose through following technical scheme: a cervical dilation balloon, comprising: the catheter comprises a catheter, a front balloon, a rear balloon, a filling head and a one-way valve; one end of the catheter is respectively connected with the front balloon and the rear balloon, and the other end of the catheter is connected with the filling head; the one-way valve is arranged in the guide pipe; the anterior balloon is larger in size than the posterior balloon.
Preferably, the catheter is provided with a mark of an insertion depth reference, and the distance from the mark of the depth reference to the outer side of the front balloon is 8.6 cm.
Preferably, the filling head is provided with a front balloon injection port and a rear balloon injection port, and recommended capacities of the front balloon and the rear balloon are marked at the front balloon injection port and the rear balloon injection port respectively.
Preferably, the catheter, the front balloon, the rear balloon and the filling head are made of silica gel.
Preferably, the material of the check valve is polypropylene and nitrile rubber polymer.
Preferably, the front balloon has a capacity of 120ml and an inflation diameter of 70 mm.
Preferably, the rear balloon has a capacity of 15ml and an inflation diameter of 30 mm.
The beneficial effects of the utility model reside in that: the utility model is used for mechanical dilatation cervix uteri, and promotes the delivery to go on smoothly to the disease that cervix uteri that causes such as uterine contraction weak can not enough expand.

Detailed Description
The invention will be further described with reference to specific examples, but the scope of protection of the invention is not limited thereto:
example (b): as shown in fig. 1, a cervical dilatation balloon catheter is composed of a catheter 1, a front balloon 2, a rear balloon 3, an inflation head 4 and a one-way valve. One end of the catheter 1 is respectively connected with the front balloon 2 and the rear balloon 3, and the other end is connected with the filling head 4; the one-way valve is arranged inside the conduit 1; the size of the anterior balloon 2 is larger than the size of the posterior balloon 3. The catheter 1 is provided with a mark 5 of an insertion depth reference, and the distance from the mark of the depth reference to the outer side of the front balloon is 8.6 cm. The filling head 4 is provided with a front balloon injection port 6 and a rear balloon injection port 7, and recommended capacities of the front balloon 2 and the rear balloon 3 are marked at the front balloon injection port 6 and the rear balloon injection port 7 respectively. The catheter 1, the front balloon 2, the rear balloon 3 and the filling head 4 are made of silica gel. The material of the one-way valve adopts polypropylene and nitrile rubber polymer. The front balloon 2 had a volume of 120ml and an inflation diameter of 70 mm. The rear balloon 3 had a volume of 15ml and an inflation diameter of 30 mm.
The utility model is a disposable instrument after ethylene oxide sterilization before use. When the artificial uterine neck is used, the two balloons are placed in the cervix after air and water are pumped out, the balloons are inflated after being injected with sterilized distilled water, mechanical stimulation generated by inflation of the balloons induces uterine contraction, and a baby is pushed to pass through the cervical orifice more conveniently and smoothly, so that the aim of delivering smoothly is fulfilled.
The foregoing is directed to embodiments of the present invention and other technical principles, and further embodiments of the invention may be devised without departing from the basic scope thereof, and the scope thereof is determined by the claims that follow.
