Description

Technical Field

[0001] This utility model belongs to the field of duct balloons, specifically a novel bronchial duct balloon. Background Technology

[0002] A bronchial balloon is a medical device used in bronchial-related medical procedures, primarily for treatment or intervention within the bronchi.

[0003] When used, bronchial tube balloons are used to compress and stop bleeding at bronchial bleeding points. First, a person takes the tube and inserts both the tube and balloon into the patient's bronchus, moving the balloon to the bleeding point. Then, the balloon is inflated to compress the bleeding point, achieving hemostasis. After hemostasis is achieved, the balloon is deflated to shrink, allowing the balloon and tube to be removed, completing the hemostasis procedure. However, in existing technology, the balloon is deflated directly during extubation, causing rapid gas expulsion. This can easily lead to balloon deformation or uneven shrinkage, resulting in a size larger than the tube. This creates resistance during extubation, making the process difficult and potentially damaging surrounding bronchial tissues, reducing the convenience and safety of use.

[0004] In summary, this utility model provides a novel bronchial catheter balloon to solve the above-mentioned problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A novel bronchial catheter balloon includes a catheter assembly, a balloon assembly disposed on the surface of the catheter assembly, and an air delivery assembly disposed on one side of the catheter assembly. The catheter assembly includes an outer tube, and an inner tube is disposed within the inner lumen of the outer tube. A connector is disposed at the top of the outer tube. The balloon assembly includes an outer balloon, and an inner balloon is fixedly connected to the inner wall of the outer balloon. Elastic bands are fixedly connected to the upper and lower ends of the inner lumen of the inner balloon. The air delivery assembly includes a buffer tube, and an inflation tube is disposed at the top of the buffer tube. A baffle is fixedly connected to the inner lumen of the buffer tube, and an air delivery tube is connected to the bottom of the buffer tube.

[0007] Furthermore, in this invention, the outer capsule is fixedly connected to the outer tube, and the inner cavity of the outer capsule is connected to the inner cavity of the outer tube.

[0008] Furthermore, in this utility model, the end of the gas delivery pipe away from the buffer pipe is fixedly connected to the outer pipe, and the inner cavity of the buffer pipe is connected to the inner cavity of the outer pipe.

[0009] Furthermore, in this invention, the end of the elastic band away from the inner bladder is fixedly connected to the surface of the inner tube, the outer bladder is made of silicone, the inner bladder is made of polyurethane, and the elastic band is made of polyether ester elastomer.

[0010] Furthermore, in this utility model, the air injection pipe can be connected to an external air injection device, the bottom of the air injection pipe is fixedly connected to a buffer pipe, and the inner cavity of the buffer pipe is connected to the inner cavity of the air injection pipe, and a round cover is movably connected to the top of the air injection pipe.

[0011] Furthermore, in this invention, the bottom of the connector is connected to a connecting pipe, the bottom of which extends into the inner cavity of the inner tube and is movably connected to the inner cavity of the inner tube.

[0012] Beneficial effects: This utility model has the following beneficial effects:

[0013] This invention uses a catheter assembly to guide a balloon assembly into the bleeding point of the patient's bronchus. Inflation of the balloon assembly via the gas delivery assembly causes the outer balloon, inner balloon, and elastic band to gradually expand and deform, thereby compressing the bleeding point and achieving hemostasis. Opening the inflation tube allows gas from the outer balloon to gradually flow into the inner lumen of the outer tube, which then transmits the gas to the inner lumen of the gas delivery tube and buffer tube. A baffle plate inside the buffer tube impedes the gas flow, reducing its velocity. The slow expulsion of gas, combined with the repositioning elasticity of the inner and outer balloons and the elastic band, gradually reduces the volume of the outer balloon until it matches the diameter of the outer tube. This matching diameter effectively prevents resistance during extubation, thus avoiding damage to surrounding bronchial tissues and ensuring convenience and safety during use.

Various aspects of this utility model are described in this disclosure with reference to the accompanying drawings, which illustrate numerous illustrative embodiments. The embodiments of this disclosure are not necessarily defined to include all aspects of this utility model. It should be understood that the various concepts and embodiments described above, as well as those described in more detail below, can be implemented in any of many ways, because the concepts and embodiments disclosed in this utility model are not limited to any particular implementation. Furthermore, some aspects of this utility model can be used alone or in any suitable combination with other aspects disclosed in this utility model.

[0022] Example 1

[0023] like Figure 1-5 As shown, this is the first embodiment of the present invention. This embodiment provides a novel bronchial catheter balloon, including a catheter assembly 1, a balloon assembly 2 disposed on the surface of the catheter assembly 1, and an air delivery assembly 3 disposed on one side of the catheter assembly 1. The catheter assembly 1 includes an outer tube 11, and an inner tube 12 disposed in the inner cavity of the outer tube 11. A connector 13 is disposed at the top of the outer tube 11. The balloon assembly 2 includes an outer balloon 21, and an inner balloon 22 is fixedly connected to the inner wall of the outer balloon 21. An elastic band 23 is fixedly connected to the upper and lower ends of the inner cavity of the inner balloon 22. The air delivery assembly 3 includes a buffer tube 31, and an injection tube 34 is disposed at the top of the buffer tube 31. A baffle 32 is fixedly connected to the inner cavity of the buffer tube 31, and an air delivery tube 33 is connected to the bottom of the buffer tube 31.

[0024] like Figure 1-5As shown, the balloon assembly 2 can be inserted into the bleeding point of the patient's bronchus via the catheter assembly 1. The balloon assembly 2 is inflated by the gas delivery assembly 3, causing the outer balloon 21, inner balloon 22, and elastic band 23 to gradually expand and deform, thereby compressing the bleeding point and achieving hemostasis. When the inflation tube 34 is opened, the gas inside the outer balloon 21 is gradually transferred to the inner lumen of the outer tube 11. The outer tube 11 then transfers the gas to the inner lumen of the gas delivery tube 33 and the buffer tube 31. The baffle 32 inside the buffer tube 31 can block the gas, thereby reducing the gas flow rate. The slow expulsion of the gas, combined with the repositioning elasticity of the inner balloon 22, outer balloon 21, and elastic band 23, allows the outer balloon 21 to gradually decrease in volume until it matches the diameter of the outer tube 11. By ensuring that the outer balloon 21 matches the diameter of the outer tube 11, the resistance generated during extubation can effectively prevent damage to the tissues around the bronchus, ensuring convenience and safety during use.

[0025] Example 2

[0026] Reference Figure 1-3 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0027] In this embodiment, the outer bladder 21 is fixedly connected to the outer tube 11, and the inner cavity of the outer bladder 21 is connected to the inner cavity of the outer tube 11.

[0028] The end of the gas supply pipe 33 away from the buffer pipe 31 is fixedly connected to the outer pipe 11, and the inner cavity of the buffer pipe 31 is connected to the inner cavity of the outer pipe 11.

[0029] The end of the elastic band 23 away from the inner bladder 22 is fixedly connected to the surface of the inner tube 12. The outer bladder 21 is made of silicone, and the inner bladder 22 is made of polyurethane material. The elastic band 23 is made of polyether ester elastomer.

[0030] like Figure 1-3 As shown, the outer capsule 21 is connected to the inner cavity of the outer tube 11, and the buffer tube 31 is also connected to the inner cavity of the outer tube 11. Thus, the buffer tube 31 can transmit the injected gas to the inner cavity of the outer tube 11, and the outer tube 11 can transmit the gas to the inner cavity of the outer capsule 21, thereby facilitating the gradual expansion of the outer capsule 21. Since the outer capsule 21 is made of silicone, the inner capsule 22 is made of polyurethane, and the elastic band 23 is made of polyether ester elastomer, the balloon assembly 2 can have good reset effect and elasticity, enabling it to effectively recover after being subjected to external force.

[0031] Example 3

[0032] Reference Figure 4 and 5 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0033] In this embodiment, the air injection pipe 34 can be connected to an external air injection device. The bottom of the air injection pipe 34 is fixedly connected to the buffer pipe 31, and the inner cavity of the buffer pipe 31 is connected to the inner cavity of the air injection pipe 34. A round cover is movably connected to the top of the air injection pipe 34.

[0034] The bottom of the connector 13 is connected to the connecting pipe 131, the bottom of the connecting pipe 131 extends into the inner cavity of the inner tube 12 and is movably connected to the inner cavity of the inner tube 12.

[0035] like Figure 4 and 5 As shown, during gas injection, the gas injection pipe 34 can be connected to an external gas injection device, thereby transmitting gas to the inner cavity of the buffer pipe 31. After gas injection is completed, the gas injection pipe 34 can be sealed by the round cover to effectively prevent gas leakage. When the outer pipe 11 and the connector 13 are connected, the connector 13 drives the connecting pipe 131 into the inner cavity of the inner pipe 12, thereby achieving a snap-fit ​​and completing the connection between the outer pipe 11 and the connector 13, and making the inner cavities of the inner pipe 12, the connector 13 and the connecting pipe 131 connected.

[0036] In use, the catheter assembly 1 is first taken by personnel, and the balloon assembly 2 is inserted into the bronchial bleeding point of the patient through the catheter assembly 1. Gas is delivered to the inner lumen of the buffer tube 31 through the injection tube 34 in conjunction with the external injection device. The baffle 32 inside the buffer tube 31 slows down the gas flow rate, allowing the gas to be slowly delivered to the inner lumen of the delivery tube 33. The delivery tube 33 delivers gas to the inner lumen of the outer tube 11 and the outer balloon 21. The slow injection of gas causes the outer balloon 21 to expand evenly. The outer balloon 21 causes the inner balloon 22 and the elastic band 23 to stretch and deform synchronously. The expanded outer balloon 21 compresses the bronchial bleeding point to achieve hemostasis. After hemostasis is achieved, the injection tube 34 is opened by separating it from the round cap. The gas inside the outer capsule 21 is gradually transferred to the inner cavity of the outer tube 11. The outer tube 11 then transfers the gas to the inner cavities of the gas delivery tube 33 and the buffer tube 31. The baffle 32 inside the buffer tube 31 can block the gas flow, thereby reducing the gas velocity. As the gas is slowly discharged, the outer capsule 21 gradually reduces in volume. Since the inner capsule 22 and the elastic band 23 have good restoring and tensile forces, the restoring elasticity of the inner capsule 22 and the elastic band 23 can gradually reduce the volume of the outer capsule 21 to be consistent with the diameter of the outer tube 11. Afterwards, since the outer capsule 21 and the outer tube 11 have the same diameter, the resistance generated during tube removal is prevented, and damage to the tissues around the bronchus is avoided, ensuring convenience and safety during use.
