Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a multifunctional intrauterine balloon. Background Art

[0002] Clinically, various intrauterine surgeries such as artificial abortion, intrauterine adhesion separation or myomectomy, uterine septum resection, etc. are gradually increasing. After intrauterine surgery, if the intrauterine wound is not isolated, adhesion of the intrauterine wall is prone to occur. Once adhesion of the intrauterine wall occurs, it will make it difficult for the intrauterine secretions to be discharged, causing a series of symptoms such as intrauterine infection and dysmenorrhea.

[0003] At present, intrauterine balloons are needed to isolate the inner walls of the uterus from each other, thereby preventing intrauterine adhesions. The current intrauterine balloons have the following shortcomings:

[0004] 1. At present, when inserting the intrauterine balloon into the uterine cavity, the balloon needs to be folded into a tube, and after the cervical opening is expanded to the maximum, the balloon can be clamped with a clip before it can be smoothly inserted into the uterine cavity. This is not only inconvenient to use, but also the clip may damage the balloon of the multifunctional intrauterine balloon during the insertion process, causing the inserted balloon to lose its isolation effect;

[0005] 2. After the intrauterine balloon is inflated with water, the balloon may not fit the contour of the uterine cavity, affecting the effect of use.

[0006] 3. The current drug delivery method of intrauterine balloon is only a channel in the tube wall. After drug delivery, the drug distribution in the uterus is relatively limited and cannot be evenly distributed on the inner wall of the uterus, which affects the drug delivery effect.

[0007] 4. The surface of the current intrauterine balloons is a smooth structure. If the balloon is inflated with water, the balloon surface may completely cover and compress the inner wall of the uterine cavity, which may cause local ischemia and hypoxia, and is not conducive to the recovery of the uterine cavity wound.

[0008] 5: The situation inside the uterine cavity cannot be observed. The condition cannot be judged. Only the situation of the wound surface inside the uterine cavity can be estimated. Utility Model Content

[0009] The technical solution to be solved by the utility model is to provide a multifunctional intrauterine balloon, and the use of the multifunctional intrauterine balloon can solve the technical problems mentioned in the background technology.

[0010] The technical solution adopted by the utility model is: a multifunctional uterine intrauterine balloon, which includes a drainage tube, a first balloon and a second balloon, one end of the drainage tube passes through the first balloon and the second balloon, the first balloon is wrapped outside the second balloon, and the first balloon and the second balloon are both connected to the drainage tube, the drainage tube is integrated with a drug cavity, a balloon cavity and a drainage cavity, the other end of the drainage tube is provided with a drainage port, a drug injection port and a balloon injection port, the drainage cavity is connected with the drainage port, one end of the balloon cavity is connected with the second balloon, the other end of the balloon cavity is connected with the balloon injection port, and a drug inlet is provided between the connection between the first balloon and the drainage tube and the connection between the second balloon and the drainage tube, one end of the drug cavity is connected with the drug inlet, the other end of the drug cavity is connected with the drug injection port, and the outer surface of the first balloon is provided with a plurality of circular holes for drug outflow.

[0011] Preferably, it also includes a leak-proof balloon, which is located below the first balloon and connected to the drainage tube. A leak-proof balloon cavity is integrated in the drainage tube, and a leak-proof balloon injection port is also provided at the other end of the drainage tube. One end of the leak-proof balloon cavity is connected to the leak-proof balloon, and the other end of the leak-proof balloon cavity is connected to the leak-proof balloon injection port.

[0012] Preferably, the leak-proof balloon is gourd-shaped, with two sides of the leak-proof balloon connected to drainage tubes, and a middle portion for medium injected from an injection port of the leak-proof balloon to flow in and expand the leak-proof balloon.

[0013] Preferably, the circular holes are pinpoint-shaped circular holes, and the pinpoint-shaped circular holes are evenly arranged on the outer surface of the first balloon.

[0014] Preferably, a plurality of protrusions are arranged on the outer surface of the first balloon.

[0015] Preferably, the protrusions are dot-shaped protrusions, and the dot-shaped protrusions are evenly arranged on the outer surface of the first balloon.

[0016] Preferably, the drainage tube, the first balloon and the second balloon are all made of transparent materials, and a micro camera and a wireless communication module for transmitting image information captured by the micro camera are embedded in the tube wall of the drainage tube.

[0017] Preferably, the micro camera is a micro camera with a light source.

[0018] Preferably, the drainage tube is provided with a scale.

[0019] Preferably, an anti-reflux drainage bag is provided on the drainage port.

[0020] Compared with the prior art, the utility model has the following advantages: by setting a drug inlet between the first balloon and the second balloon, and then allowing the drug to flow out through the circular holes on the outer surface of the first balloon, the drug can flow evenly to the uterine wall and achieve a slow release effect.

[0021] A leak-proof balloon is set up so that it can block the area below the cervix during use to prevent the drug from leaking out, allowing the drug to be retained in the uterine cavity as much as possible to prevent drug leakage and the resulting deterioration of efficacy.

[0022] A gourd-shaped leak-proof balloon is used, which has a better sealing effect and can better retain the drug in the uterine cavity.

[0023] The needle-shaped circular holes are used so that the drug can slowly flow out from the needle-shaped circular holes to achieve a sustained release effect, and is evenly distributed on the outer surface of the first balloon, so that the drug distribution is also relatively uniform.

[0024] A plurality of protrusions are arranged on the outer surface of the first balloon, so as to avoid the balloon surface completely covering the inner wall of the uterine cavity, causing local ischemia and hypoxia, which is beneficial to the recovery of the uterine cavity wound surface.

[0025] The dot-shaped protrusions are evenly distributed on the surface of the first balloon, which can better avoid the balloon surface from fully covering the inner wall of the uterine cavity, thereby achieving a better recovery effect of the uterine cavity wound.

[0026] The drainage tube, the first balloon and the second balloon are all made transparent, and a miniature camera is embedded in the inner wall of the drainage tube. This allows the doctor to take pictures of the situation in the uterine cavity and make an intuitive judgment on the condition.

[0027] Using a miniature camera with a light source can better view the situation inside the uterine cavity.

[0028] Graduations are set on the drainage tube to facilitate the user to place the stent in a suitable position.

[0029] An anti-reflux drainage bag is provided at the drainage port to prevent reflux. BRIEF DESCRIPTION OF THE DRAWINGS
