Description

Technical Field

[0001] This utility model belongs to the field of medical technology, specifically relating to a sliding balloon-type cervical dilation balloon. Background Technology

[0002] In obstetrics and gynecology, cervical dilation balloons are commonly used tools for promoting cervical ripening and inducing labor. However, traditional cervical dilation balloons have certain limitations. On the one hand, most balloons have a fixed structure and cannot flexibly adapt to the physiological differences in the cervix of different mothers. The length, shape, and elasticity of the cervix vary from mother to mother, and a fixed-structure balloon cannot accurately apply appropriate pressure to different parts of the cervix, resulting in poor dilation. On the other hand, existing balloons are prone to displacement or excessive local pressure on the cervix during placement and operation, increasing the discomfort of the mother and potentially causing unnecessary damage to the cervical tissue, affecting the subsequent delivery process. Utility Model Content

[0003] The purpose of this invention is to provide a sliding balloon-type cervical dilation balloon, which aims to solve the above-mentioned technical problems.

[0004] This utility model provides a sliding balloon-type cervical dilation balloon, including a closed catheter. A fixed balloon is fixedly connected to one end of the catheter. The bottom of the fixed balloon is provided with a sliding balloon that is slidably connected to the outside of the catheter via a sliding mechanism. The sliding mechanism includes a sliding ring fitted with the catheter, which is fixedly embedded inside the sliding balloon. A sliding tube communicating with the inside of the sliding balloon is fixedly connected to the bottom of the sliding ring. One side of the sliding tube is slidably connected to a groove formed on the surface of the catheter. A limiting collar is also fitted outside the sliding tube and is fixedly connected to the outside of the catheter. An annular push plate is fixedly connected to one end of the sliding tube. An injection tube communicating with the inside of the sliding tube is connected to one side of the push plate. The injection tube is connected to a first injection connector. The fixed balloon is connected to a second injection port through the injection tube built into the catheter.

[0005] In one embodiment of this utility model, a guide wire is inserted and connected inside the catheter, and a pull ring is fixedly connected to one end of the guide wire.

[0006] In one embodiment of this utility model, both the fixed balloon and the sliding balloon are disc-shaped after being filled with fluid.

[0007] In one embodiment of this utility model, the cross-section of the slide groove is T-shaped, and the slide groove slides in conjunction with the protrusions on both sides of the sliding tube.

[0008] In one embodiment of this utility model, the shapes of the first injection connector and the second injection interface are both adapted to the shape of the syringe.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] This utility model's sliding balloon-type cervical dilation balloon, through its sliding mechanism—utilizing the cooperation of a sliding ring, sliding tube, and groove on the catheter—allows the balloon to slide along the catheter. It can be adjusted according to the actual length and shape of the mother's cervix, precisely positioning it in the appropriate location. This ensures even pressure is applied to the internal and external os of the cervix and different areas, effectively promoting cervical dilation. The limiting ring prevents excessive sliding of the balloon, ensuring its stability. Furthermore, the guidewire and pull ring configuration facilitates precise operation by medical staff during balloon placement and adjustment, improving the mother's comfort during use. This provides strong support for safe and efficient cervical dilation and labor induction, effectively promoting cervical ripening in pregnant women. Attached Figure Description

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] Example 1

[0018] Please see Figure 1-3 A sliding balloon-type cervical dilation balloon includes a closed catheter 100. A fixed balloon 200 is fixedly connected to one end of the catheter 100. A sliding balloon 400 is provided at the bottom of the fixed balloon 200 and is slidably connected to the outside of the catheter 100 via a sliding mechanism 300. The sliding mechanism 300 includes a sliding ring 310 sleeved on the catheter 100, which is fixedly embedded inside the sliding balloon 400. A sliding tube 320 communicating with the inside of the sliding balloon 400 is fixedly connected to the bottom of the sliding ring 310. The sliding tube 320 is slidably connected to the groove 330 on the surface of the catheter 100. A limiting collar 340 is also fitted on the outside of the sliding tube 320. The limiting collar 340 is fixedly connected to the outside of the catheter 100. An annular push plate 350 is fixedly connected to one end of the sliding tube 320. A liquid injection hose 360 ​​communicating with the inside of the sliding tube 320 is connected to one side of the push plate 350. The liquid injection hose 360 ​​is connected to a first injection connector 500. The fixed balloon 200 is connected to a second injection port 600 through a liquid injection tube built into the catheter 100.

[0019] Specifically, when cervical dilation is required, the catheter 100 is carefully inserted into the cervix. A fixed balloon 200 is attached to one end of the catheter 100, maintaining a relatively stable position within the cervix and applying continuous pressure near the internal cervical os. Then, based on the actual length and shape of the cervix, medical personnel can inject an appropriate amount of fluid into the sliding balloon 400 via the push plate 350, the injection tubing 360, and the first injection connector 500. As the fluid is injected, the sliding balloon 400 inflates, simultaneously with the cooperation of the sliding tube 320 and the groove 330. Under these conditions, the balloon 200 can slide along the catheter 100 to a suitable position. At this time, the fixed balloon 200 and the sliding balloon 400 apply pressure to the internal and external os of the cervix and different parts, respectively, to promote cervical dilation. The limiting ring 340 can effectively prevent the sliding balloon 400 from sliding excessively, ensuring that the balloon is always within the appropriate working range and maintaining stable pressure on the cervix. The fixed balloon 200 is connected to the second injection port 600 through the infusion tube built into the catheter 100, which facilitates medical staff to perform individual infusion operations to adjust the pressure of the fixed balloon 200 and further optimize the effect on the cervix.

[0020] In this embodiment, a guide wire 110 is inserted and connected inside the catheter 100, and a pull ring 120 is fixedly connected to one end of the guide wire 110.

[0021] Specifically, before inserting catheter 100, medical staff can hold pull ring 120 and adjust the position of guidewire 110 within catheter 100 by controlling the movement of pull ring 120, thereby adjusting the shape of the catheter tip to better conform to the physiological curvature of the cervix. During insertion, if the position of catheter 100 needs fine-tuning, medical staff can pull or push pull ring 120 to move guidewire 110, thus changing the direction of catheter 100. Once catheter 100 reaches the predetermined position, if further adjustment of balloon position is needed, the cooperation of guidewire 110 and pull ring 120 can be used to ensure the accuracy of the operation.

[0022] In this embodiment, both the fixed balloon 200 and the sliding balloon 400 are disc-shaped after being filled with fluid.

[0023] Specifically, in the actual scenario of cervical dilation, the internal and external os of the cervix and surrounding tissues require uniform and effective pressure stimulation to promote maturation and dilation. The disc-shaped fixed balloon 200, located at the internal os of the cervix, can closely fit the edge of the internal os, distributing the pressure evenly over a large area, avoiding excessive concentrated pressure on local tissues and reducing the risk of tissue damage. At the same time, the disc-shaped sliding balloon 400, after sliding along the catheter 100 to the appropriate position, can also fit well against the external os of the cervix and surrounding areas.

[0024] In this embodiment, the cross-section of the groove 330 is T-shaped, and the groove 330 slides in conjunction with the protrusions on both sides of the sliding tube 320.

[0025] Specifically, the T-shaped groove 330 and the sliding tube 320 slide in cooperation, allowing the sliding balloon 400 to slide on the correct track. At the same time, the stable sliding also ensures the accuracy of the balloon when applying pressure to the cervix.

[0026] In this embodiment, the shapes of the first injection connector 500 and the second injection interface 600 are both adapted to the shape of the syringe.

[0027] Specifically, when it is necessary to infuse fluid into the balloon, medical staff only need to connect the syringe containing an appropriate amount of sterile fluid directly to the first injection connector 500 or the second injection interface 600. The appropriate shape design ensures a tight connection between the syringe and the injection connector, avoiding fluid leakage during the filling process.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
