Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an anti-blocking and anti-adhesion uterine intracavitary balloon device. Background Art

[0002] After uterine curettage, intrauterine adhesions can develop due to endometrial trauma, leading to fertilization and implantation difficulties and, consequently, infertility risks for women who wish to have children. Therefore, clinically, women planning fertility require postoperative adhesion prevention. Using a balloon to expand the uterine cavity, preventing adhesions from forming within the wound, is an effective method for preventing adhesions. However, in cases of cervical stenosis, the balloon catheter can easily block the passage of blood clots and exfoliated endometrium, leading to pain and intrauterine inflammation, and affecting intrauterine medication use. Summary of the Invention

[0003] In response to the shortcomings of the above-mentioned existing production technology, the present application provides an anti-blockage and anti-adhesion intrauterine balloon device, which can not only expand the uterine cavity through the balloon to prevent adhesions in the uterine cavity after curettage, but also avoid the balloon catheter from blocking the cervix, bringing convenience to recovery after curettage.

[0004] The technical solutions adopted in the present invention are as follows:

[0005] An anti-blocking and anti-adhesion intrauterine balloon device comprises a double-lumen catheter, wherein an air cavity and an injection cavity are arranged side by side in the tube body of the double-lumen catheter, a balloon is wrapped around the upper end surface of the double-lumen catheter, an air outlet end of the air cavity of the double-lumen catheter is connected to the inner cavity of the balloon, and a liquid outlet end of the injection cavity of the double-lumen catheter is exposed on the outer surface of the balloon; a cervical dilator tube is sheathed on the surface of the double-lumen catheter, an outer surface of one side of the double-lumen catheter is fixedly connected to the inner surface of the cervical dilator tube, and a plurality of meshes are evenly arranged on the surface of the cervical dilator tube; a plurality of skirts are arranged on the lower end of the cervical dilator tube along the circumferential direction, and the plurality of skirts can overlap on the surface of the double-lumen catheter to shield the lower end of the cervical dilator tube.

[0020] The specific embodiments of the present invention will be described below with reference to the accompanying drawings.

[0021] like Figure 1 As shown, the anti-blocking and anti-adhesion intrauterine balloon device includes a double-lumen catheter 1, in which an air cavity and an injection cavity are arranged side by side. The air cavity is used to introduce a gas medium, and the injection cavity is used to introduce a liquid medium.

[0022] like Figure 1As shown, a double-lumen catheter 1 has an elastically extendable tubular section 2 disposed in the middle thereof. The elastically extendable tubular section 2 has a spiral structure and can be elastically extended or retracted under external force. During use, the elastically extendable tubular section 2 can be pulled out of the vaginal opening for operation and retracted back into the vagina after release.

[0023] like Figure 1 As shown, a balloon 3 is wrapped around the upper surface of a double-lumen catheter 1. The air outlet of the double-lumen catheter 1 is connected to the inner lumen of the balloon 3, and the liquid outlet of the injection lumen of the double-lumen catheter 1 is exposed on the outer surface of the balloon 3. During use, the balloon 3 is inflated through the air lumen of the double-lumen catheter 1. After inflation, the balloon 3 forms a flat heart-shaped structure, which can expand the uterine cavity and prevent contact and adhesion of the uterine curettage wound surface.

[0024] like Figure 1 and Figure 3 As shown, a cervical dilator tube 4 is sheathed over a dual-lumen catheter 1. The outer surface of one side of the dual-lumen catheter 1 is fixedly connected to the inner surface of the cervical dilator tube 4. Multiple mesh holes 5 are evenly distributed on the surface of the cervical dilator tube 4. Made of an elastic material, the mesh holes 5 facilitate the drainage of cervical fluid secretions. During use, the cervical dilator tube 4 extends from the internal cervical os and terminates in the vagina outside the cervical os. This supports the cervical os, facilitating the discharge of blood clots and other excretions within the uterine cavity.

[0025] like Figure 1 and Figure 3 As shown, a plurality of skirts 6 are provided along the circumferential direction at the lower end of the cervical dilator tube 4. The skirts 6 are made of a soft silicone membrane. The plurality of skirts 6 can overlap the surface of the double-lumen catheter 1 to shield the lower end of the cervical dilator tube 4 to prevent pathogens in the vagina from entering the uterine cavity along the double-lumen catheter 1. When blood clots flow out of the cervical dilator tube 4, it can be expanded for normal excretion.

[0026] like Figure 4 As shown, the lower end of the double-lumen catheter 1 is connected to the filling connector 8, and an air inlet and a liquid inlet are arranged side by side on the filling connector 8. The air inlet is connected to the air inlet end of the air cavity of the double-lumen catheter 1, and an air inlet plug 9 is provided in the air inlet for sealing. The liquid inlet is connected to the liquid inlet end of the injection cavity of the double-lumen catheter 1, and a liquid inlet plug 10 is provided in the liquid inlet for sealing.

[0027] like Figure 1 As shown, the inner surface of the cervical dilator tube 4 is provided with a detachable connecting guide wire 7, which can temporarily position the entire balloon device in the uterus. When the guide wire 7 is pulled out of the vagina, it can be separated from the cervical dilator tube 4. The guide wire 7 is a metal wire or polymer material wire with elastic hardness and scale marks on the surface.

[0028] The present invention is in standby mode, as Figure 2As shown, the balloon 3 is in a vacuum state and is attached to the upper surface of the double-lumen catheter 1. A sheath 11 is sheathed on the outer surface of the cervical dilator tube 4, and a scale size is set on the sheath 11 along the length direction.

[0029] The working principle of the present invention is: after the uterine curettage operation is completed, a sheath tube 11 with a diameter smaller than or equal to that of the uterine curettage negative pressure suction tube is inserted into the uterine cavity. Note that the guide wire 7 scale shows that the cervical dilation tube 4 is in place and then stopped (compared with the uterine depth detected by the bougie before uterine curettage). The guide wire 7 is held up and the sheath tube 11 is withdrawn to the cervix to expose the balloon 3. A rated volume of air is injected into the air inlet end of the air cavity of the filling connector 8 with a syringe with a needle to expand the balloon 3. Then the sheath tube 11 and the guide wire 7 are removed, and the elastic telescopic tube section 2 is disinfected and retracted into the vagina.

[0030] When the medicine needs to be injected, the filling connector 8 is clamped out of the vaginal opening with tweezers, and after disinfection, the medicine is injected into the uterine cavity with a syringe with a needle at the liquid inlet end of the injection cavity.

[0031] When the device needs to be removed, use tweezers to clamp the filling port out of the vaginal opening. After disinfection, use a syringe with a needle to insert the air inlet end of the filling connector 8 to extract the gas in the balloon 3. Then, pinch the filling connector 8 with your hand and slowly pull it out of the vaginal opening to pull out the entire device.

[0032] When the guide wire 7 is not used, the balloon 3 can be packaged with the front end of the sheath 11 exposed. After entering the uterine cavity and reaching its position, a syringe with a needle is used to inject a rated volume of air into the air inlet end of the filling connector 8 to expand the balloon 3. Then the sheath 11 is removed, and the elastic telescopic tube section 2 is disinfected and retracted into the vagina.

[0033] The above description is an explanation of the present invention, not a limitation of the present invention. The scope of the present invention is defined in the claims. Any modifications may be made within the scope of protection of the present invention.
