Wherein one side of the water bag is connected with a water injection pipe, the tube core is inserted into the cervix uteri, then the tube core is taken out, and water is injected into the water bag through the water injection pipe so as to achieve cervical dilatation, and the cervical dilatation device comprises the tube core and the water bag arranged on the outer surface wall of the tube core, and the water injection pipe is further arranged on one side of the water bag and inserted into the cervix uteri through the tube core. The cervix uteri is expanded in the mode that water is injected into the water bag through the water injection pipe, the expansion size of the cervix uteri is controllable, the speed is high, the cervix uteri can be used after anesthesia, the pain of a patient is small, the outer surface wall of the water bag is provided with the elastic protection layer, and the service life of the water bag is prolonged.

The utility model relates to a rotatable cervical dilation rod, which belongs to the technical field of medical instruments and comprises a front end portion and a deformation portion, the front end portion is guided to penetrate into the cervix, and the deformation portion is arranged at one end of the front end portion and used for dilating the cervix. The deformation part comprises an air cylinder fixedly connected to one end of the front end part, an air bag fixedly connected to the outer portion of the air cylinder in a sleeving mode, an injection opening formed in the end, close to the front end part, of the air cylinder, and a piston assembly arranged in the air cylinder and used for injecting air in the air cylinder into the air bag from the injection opening. The size of the air bag can be adjusted to achieve gradual expansion of the cervix uteri, compared with a traditional mode that metal cervix uteri rods of different sizes repeatedly enter and exit the uterine cavity one by one for expansion, efficiency is high, the operation process is greatly simplified, and operation cost is reduced. Therefore, infection caused by repeatedly entering and exiting the uterine cavity can be reduced, and the probability of cervical injury and uterine perforation is reduced.

The present invention relates to the technical field of medical instruments, in particular to an anti-blocking and anti-adhesion intrauterine balloon device. The anti-blocking and anti-adhesion intrauterine balloon device comprises a dual lumen cannula, a balloon is wrapped on the surface of the upper end of the dual lumen cannula, an air outlet end of an air cavity of the dual lumen cannula is communicated with an inner cavity of the balloon, and a liquid outlet end of an injection cavity of the dual lumen cannula is exposed out of the outer surface of the balloon; a cervical dilatation tube is sleeved on the surface of the dual lumen cannula, and the outer surface of one side of the dual lumen cannula is fixedly connected to the inner surface of the cervical dilatation tube; and the lower end of the cervical dilatation tube is circumferentially provided with a plurality of skirt edges that can be connected to the surface of the dual lumen cannula to shield the lower end of the cervical dilatation tube. The present invention can prevent adhesion of the uterine cavity after dilatation and curettage by dilating the uterine cavity by means of the balloon; and according to the prevent invention, the cervical dilatation tube widens the cervix, and then the lower end of the cervical dilatation tube is sealed by means of the skirt edges, thereby preventing pathogens in the vagina from entering the uterine cavity, and when blood clots flow out of the cervical dilatation tube, the cervix can be widened for normal excretion.

The invention belongs to the technical field of medical instruments, particularly relates to a disposable cervical dilatation balloon catheter and an assembling method thereof, and aims to solve the problem that when an existing disposable cervical dilatation balloon catheter is used for dilating the cervix of a puerpera, a large space is still reserved between a uterus balloon and a vagina balloon on the catheter after normal saline is injected into the uterus balloon and the vagina balloon for dilation, and the uterus balloon and the vagina balloon cannot be used for dilating the cervix of the puerpera. In order to solve the problem that the mature state of the cervix uterus and the success rate of labor induction are affected due to incomplete expansion of the cervix uterus of a lying-in woman, the following scheme is provided: the device comprises an outer catheter, and a vagina balloon and a uterus balloon are arranged outside the outer catheter. According to the disposable cervical dilation balloon catheter and the assembling method thereof, the disposable cervical dilation balloon catheter can fully dilate the cervix of a puerpera during labor induction, so that the size of a gap between the vagina balloon and the uterus balloon after dilation is reduced, and the cervix of the puerpera reaches a completely dilated mature state; the labor induction success rate of the puerpera is improved.

The utility model provides a kind of slidable balloon type cervical dilatation balloon, including closed catheter, the one end outside fixed connection of catheter has fixed balloon, the bottom of fixed balloon is equipped with the sliding balloon of being slidably connected with the outside of catheter by sliding mechanism, sliding mechanism includes the sliding ring of being sleeved with catheter, sliding ring is fixedly embedded in the inside of sliding balloon, the slidable balloon type cervical dilatation balloon of the utility model is slidably connected by being equipped with sliding mechanism, using the cooperation of sliding ring, sliding tube and upper slide groove of catheter, make sliding balloon can slide along catheter, can be adjusted according to the actual length and form of puerperal cervix, accurately positioned in suitable position, improve the comfort degree of puerperal in use process, provide strong support for safe, efficient cervical dilatation and induction, effectively guarantee to promote cervical ripening for pregnant woman.

The application discloses a device for delaying premature delivery, which comprises a plurality of split rings arranged in a ring structure in sequence along a circumference, a fixing ring and a connecting piece. Each split ring comprises an upper ring body and a lower ring body, the fixing ring is sleeved on each lower ring body, and the connecting piece is connected to each adjacent two upper ring bodies. The device further comprises a locking structure for locking the position of the upper ring body and the connecting piece, which is arranged between the connecting piece and one upper ring body connected thereto. The locking structure has a plurality of locking positions, and the inner diameter of the ring structure formed by each upper ring body is different at different locking positions. The locking structure can automatically adjust the locking structure to be in different locking positions according to the ligation force. The device can effectively prevent cervical dilatation and thinning, prevent or delay premature delivery, avoid amniotic sac inflammation, and avoid the increase of the ligation force with the increase of the weight of the baby, thereby avoiding the damage to the cervix and the discomfort and pain of the patient.
