Description

Technical Field

[0001] The utility model relates to the technical field of instruments for introducing or retaining a medium, such as medicine, in a body cavity, and in particular to an intracavitary anti-adhesion balloon structure after uterine cavity surgery. Background Art

[0002] In the prior art, the post-operative intrauterine adhesion prevention device is an intrauterine balloon. When the common intrauterine balloon is used, water is often injected or air is inflated in the balloon to open the balloon to support the uterine cavity. However, when the existing balloon is inflated and opened, the balloon expands outward as a whole, causing the inner wall of the uterine cavity to open outward as a whole, resulting in the risk of the surgical area being torn. Therefore, a post-operative intrauterine adhesion prevention balloon structure is proposed. Utility Model Content

[0003] In order to solve at least one of the above-mentioned technical shortcomings, the utility model provides a post-operative intracavitary anti-adhesion balloon structure, including a balloon, the balloon is made of flexible material, the balloon is flat, an inflation cavity is provided inside the balloon, the top end of the connecting tube is inserted into the inflation cavity, the bottom end of the connecting tube is connected to a valve, and the top outer wall of the connecting tube is provided with a plurality of air outlet holes connected to the inflation cavity.

[0004] Furthermore, a shrinkage frame fixed on the connecting pipe is provided inside the inflation cavity.

[0005] Furthermore, a connecting horizontal block integrally connected to the inner wall of the inflation cavity is provided at the top end of the connecting pipe.

[0006] Furthermore, the shrinkage skeleton includes two fixed blocks fixed to the outer wall of the middle part of the connecting tube, the fixed blocks are located inside the inflation chamber, and at least one rotating hole is provided on the fixed blocks. A U-shaped skeleton is provided inside the rotating hole, and the two ends of the U-shaped skeleton are respectively connected to the top wall and the bottom wall of the inflation chamber, and the middle part of the U-shaped skeleton is rotatably connected to the rotating hole.

[0007] Furthermore, the top wall and the bottom wall of the inflation cavity are both concave and have a plurality of contraction grooves.

[0008] Furthermore, the balloon is made of medical silicone material.

[0009] Furthermore, an air pump is provided for inflating the air chamber. Beneficial Effects

[0010] Open the valve, first extract the gas inside the inflation cavity to form a negative pressure inside the inflation cavity, close the valve, and deflate the balloon under the action of atmospheric pressure. Send the balloon to the surgical area by holding the connecting tube. Open the valve again, and fill the gas from the outer end of the valve. The gas passes through the connecting tube into the inflation cavity, causing the deflated balloon to expand and spread out to cover the surgical area, thereby preventing adhesion to the inner wall of the uterine cavity.

[0011] When limiting the shape of the balloon, when the interior of the inflation cavity is inflated with gas, the balloon will expand under the action of air pressure, passing through the two ends of the U-shaped skeleton, so that the balloon cannot expand in the upper and lower planes, and the balloon can only expand to the left and right sides, so that the balloon is spread out flat. When expanding to the left and right, the middle part of the U-shaped skeleton rotates inside the rotating hole.
