Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical devices, and in particular to a uterine cavity anti-adhesion air bag. BACKGROUND

[0002] The wound surface of the uterine cavity left after the hysteroscopy operation will be adhered to each other, resulting in infertility. Therefore, the isolation and protection of the wound surface after the operation is not only beneficial to the healing of the wound surface, but also can avoid the uterine cavity adhesion and prevent infertility caused by this cause. At present, the gel material is injected to cover and block in the clinic, which has great uncertainty. The main reason is that the gel material has fluidity, and when it is covered on the wound surface with liquid secretion and certain activity (the uterus will move with the body), it is difficult to determine the thickness of the coverage and the length of the maintenance time, which affects the effectiveness, so the solid device is used to block than the gel.

[0003] In the prior art, Chinese patents CN204815321U and CN205626062U adopt the air bag water injection expansion method to support the uterine cavity, so that the wound surface of the uterine cavity is isolated.

[0004] This method is feasible, but the design of the two patents also has serious hidden dangers. After the air bag is injected with water, the water in the air bag will gather at the bottom of the air bag due to the influence of gravity, which will increase the weight of the prolapse of the uterus, resulting in uterine prolapse, so it has not been applied in the clinic. At the same time, the air bag seals the uterine channel, and cannot flush or administer medicine in the uterine cavity, which affects the healing effect of the uterine cavity. SUMMARY

[0005] The present application aims at the shortcomings of the above-mentioned prior art production technology, and provides a uterine cavity anti-adhesion air bag, which uses air medium to expand the uterine cavity, avoids the adhesion of the wound surfaces of the front and back walls of the uterine cavity, and since the air is uniformly dispersed in the air bag, the pressure of the air bag wall on the uterine cavity remains consistent, avoiding the occurrence of uterine prolapse. At the same time, the flushing structure arranged can flush or administer medicine in the uterine cavity, improving the healing effect of the uterine cavity.

[0006] The technical scheme adopted by the present application is as follows:

[0007] A uterine cavity anti-adhesion air bag, comprising a uterine cavity air bag, which is inflated to expand the uterine cavity. The bottom of the uterine cavity air bag is connected to an air bag inflation pipe, the upper end of the air bag inflation pipe is in communication with the air inlet and outlet of the uterine cavity air bag, and the air bag inflation pipe can inflate the uterine cavity air bag. A plurality of flushing ports are arranged at the top of the uterine cavity air bag, and the bottom of the uterine cavity air bag is connected to a flushing pipe. The uterine cavity air bag is wrapped on the flushing pipe, and the upper end of the flushing pipe extends into the uterine cavity air bag and communicates with the plurality of flushing ports.

[0008] Further, the cross-sectional area of the uterine cavity air bag after inflation decreases from top to bottom.

[0009] Further, the uterine cavity balloon surface is provided with a plurality of protruding ribs, the ribs extend along the uterine cavity balloon surface from top to bottom, and the plurality of ribs are distributed along the circumferential direction of the uterine cavity balloon.

[0010] Further, the lower end of the balloon inflation tube is connected to the inflation joint, and a one-way valve is arranged on the upper end of the balloon inflation tube.

[0011] Further, a drainage groove is arranged on the side surface of the upper end of the balloon inflation tube along the length direction, and the drainage groove is located at the uterine neck position of the uterine cavity.

[0012] Further, the lower end of the flushing pipe is connected to the syringe joint.

[0013] Further, a blocking balloon is arranged on the left and right sides of the top of the uterine cavity balloon, and the blocking balloon can block the oviduct orifice on both sides of the uterine cavity after being inflated, and the inner cavities of the uterine cavity balloon and the blocking balloon are communicated.

[0014] The beneficial effects of the present application are as follows:

[0015] The uterine cavity balloon of the present application uses air medium to expand the uterine cavity, avoiding the adhesion of the front and back wall wounds of the uterine cavity. Since the air is uniformly dispersed in the balloon, the pressure of the balloon wall on the uterine cavity remains consistent, avoiding the occurrence of uterine prolapse. The blocking balloon can block the oviduct orifice on both sides of the uterine cavity after being inflated, preventing the secretion or disinfecting flushing liquid from entering the oviduct when the pressure in the uterine cavity is increased. The ribs protruding from the surface of the uterine cavity balloon can reduce the contact area between the uterine cavity balloon and the inner wall of the uterine cavity, preventing the influence on the wound healing, and being beneficial to the cavity flushing, drug delivery and liquid flow to the uterine isthmus. The drainage groove arranged on the balloon inflation tube at the uterine neck position can weaken the obstruction of liquid discharge caused by the cervical stenosis, and drain the intrauterine liquid to the vagina. The syringe joint can inject disinfecting flushing liquid or other drug solution into the flushing pipe, and flow to the wound position in the uterine cavity through the flushing port for flushing.
