Problems solved by technology

However, because the shape of the uterine cavity is an inverted cone with a wide top and a narrow bottom, the spherical shape of the Foley catheter cannot fit the endometrium, resulting in uneven stress on the endometrium and reducing the local endometrial blood supply. , affect the regeneration of the endometrium, an

Example Embodiment

[0019] like Figure 1-2 As shown, the balloon device for preventing and treating intrauterine adhesion includes an intermediate lumen 1, the upper end of the intermediate lumen 1 is open, and the lower end of the intermediate lumen 1 is provided with an injection assembly 11, the injection assembly includes a syringe and a valve. The contents are drained, the valve is closed and the anti-adhesion or endometrial growth-promoting drug can be injected into the uterine cavity through the syringe.

[0020] The middle lumen 1 is provided with a uterine cavity water bag 2 which is inverted conical after water injection, and the uterine cavity water bag 2 surrounds the upper part of the middle lumen 1 . The uterine cavity water bag 2 is equipped with a uterine cavity water injection valve 21. By controlling the uterine cavity water injection valve 21, water is injected into the uterine cavity water bag 2. When the uterine cavity water bag 2 and the endometrium achieve the most perfect...

Abstract

The invention discloses a balloon device for preventing and treating intrauterine adhesion. The balloon device comprises a middle pipe cavity, an opening is formed in the upper end of the middle pipe cavity, an injection assembly is arranged at the lower end of the middle pipe cavity, an intrauterine water balloon which is shaped like an inverted cone after being filled with water is arranged on the portion, next to the opening, of the middle pipe cavity, the intrauterine water balloon is arranged on the upper portion of the middle pipe cavity in a surrounding mode, the intrauterine water balloon is provided with an intrauterine water injection valve in a matched mode, and the outer surface of the intrauterine water balloon is provided with an anti-adhesion membrane capable of preventing the intrauterine adhesion. By arranging the intrauterine water balloon which is shaped like the inverted cone after being filled with the water on the upper portion of the middle pipe cavity, the balloon device can be perfectly attached to the endometrium, therefore, a better anti-adhesion effect is achieved, the condition that adhesion preventing or endometrium growth promoting drugs injected into the uterine cavity flow out can be prevented, and the ascending infection risk is reduced. The balloon device can be applied to the field of medical treatment.

Description

technical field [0001] The invention relates to a medical device, in particular to a balloon device for preventing and treating intrauterine adhesion. Background technique [0002] At present, the Foley catheter is used to prevent postoperative adhesions in the uterine cavity and cervical cavity. Its structure includes a drainage tube and a balloon at about 2.5 cm from the front end of the drainage tube. The balloon is spherical after water injection, and the drainage tube The end is connected with a drainage bag, and there is a water injection soft valve on the side of the end of the drainage tube, and the length of the catheter is about 50cm. In clinical use, cut off about 1.5cm of the catheter head and place it in the uterine cavity, inject water into the balloon, prevent uterine cavity adhesion through the balloon, tie the end of the drainage tube and place it in the vagina or fix it at the root of the thigh. However, because the shape of the uterine cavity is an invert...
