Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a blood vessel closure device. Background Technology

[0002] Femoral artery puncture is a common approach in interventional vascular treatment. Vascular complications at the puncture site during the procedure are a recurring problem for interventional physicians. Methods for hemostasis at the puncture site after femoral artery intervention include manual compression and mechanical compression.

[0003] Traditional manual compression methods have a long clinical application time, but prolonged compression for hemostasis and bed rest not only increase the workload of medical staff but also increase the patient's suffering. Therefore, this invention proposes a vascular closure device to address the shortcomings of existing technologies. Utility Model Content

[0004] To address the aforementioned problems, the present invention aims to provide a vascular closure device. This device consists of a closure device at one end of an internal tube and an external plugging component on the internal tube. The closure device comprises a closure balloon, an intermediate balloon, and an internal plugging block. Inflating the closure balloon through the internal tube expands the balloon to block the inner wall of the blood vessel. Inflating the intermediate balloon pushes the internal plugging block to further clamp and block the inner wall of the blood vessel.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A vascular closure device includes an outer sheath, an inner tube, and a closure device. The outer sheath contains an inner tube, one end of which extends beyond the outer sheath and has a connecting end. The other end of the inner tube has a closure device. An external plugging assembly is movably mounted on the inner tube between the closure device and the connecting end. The closure device includes a closure balloon, an intermediate balloon, and an internal occlusion block. The closure balloon is located at one end of the inner tube, and the inner tube extends into the closure balloon. The internal occlusion blocks are symmetrically arranged inside the closure balloon. An intermediate balloon is located inside the closure balloon between two internal occlusion blocks. The intermediate balloon communicates with the inner tube, and the internal occlusion block is movably connected to the inner tube.

[0007] A further improvement is that the outer protective tube includes a round tube and a tapered tube, one end of the round tube is provided with a tapered tube, and the closure device is located inside the tapered tube.

[0008] A further improvement is that a through hole is provided at the center of the built-in sealing block, and the built-in sealing block is movably connected to the built-in tube through the through hole.

[0009] A further improvement is that: the inner wall of the closed balloon is provided with a flexible reinforcing sheet, and at least two sets of the flexible reinforcing sheet are provided; the intermediate balloon is provided with a first outlet.

[0010] A further improvement is that the outer plugging assembly includes a sheath and a piston plugging component, the sheath is movably disposed on the outer wall of the inner tube, and the piston plugging component is movably disposed inside the sheath.

[0011] A further improvement is that a second outlet is provided on the outer wall of the built-in tube inside the sheath, and the second outlet is located above the piston sealing component.

[0012] The beneficial effects of this utility model are as follows: This utility model sets a closure device at one end of the internal tube and sets an external plugging component on the internal tube. The closure device consists of a closure balloon, an intermediate balloon, and an internal plugging block. Inflating the closure balloon through the internal tube expands the closure balloon to block the inner wall of the blood vessel. After the intermediate balloon is inflated, it can push the internal plugging block to clamp and block the inner wall of the blood vessel again. The piston plugging component of the external plugging component is pushed in and moves until it blocks the outer wall of the blood vessel after inflation. The device can quickly block and close the inner and outer walls of the blood vessel to reduce the patient's pain and discomfort. Attached Figure Description

Detailed Implementation

[0023] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0024] according to Figure 1-9 As shown, this embodiment proposes a vascular closure device, including an outer protective tube 1, an inner tube 2, and a closure device 3. The outer protective tube 1 has an inner tube 2 inside it. One end of the inner tube 2 extends out of one end of the outer protective tube 1, and a connecting end 4 is provided at the end of the inner tube 2 extending out of the outer protective tube 1. The other end of the inner tube 2 has a closure device 3. An outer plugging component 5 is movably provided on the inner tube 2 between the closure device 3 and the connecting end 4. The closure device 3 includes a closure balloon 301, an intermediate balloon 302, and an inner occlusion block 303. The closure balloon 301 is disposed at one end of the inner tube 2, and one end of the inner tube 2 extends into the interior of the closure balloon 301. The inner occlusion blocks 303 are symmetrically disposed inside the closure balloon 301. An intermediate balloon 302 is provided inside the closure balloon 301 between the two inner occlusion blocks 303. The intermediate balloon 302 is connected to the inner tube 2, and the inner occlusion block 303 is movably connected to the inner tube 2.

[0025] When using the vascular closure device of this utility model, the device is inserted into the blood vessel using a sheath, then the sheath is removed, followed by the removal of the outer protective tube 1. Inflation is then performed through the internal tube 2, causing the closure balloon 301 to be inflated. During inflation, the external plugging component 5 is also inflated, causing the piston sealing component 502 to be compressed and moved until it approaches the outer side of the blood vessel to seal it. As the closure balloon 301 continues to be inflated, the intermediate balloon 302 is expanded, which pushes the internal sealing block 303 to move until the internal sealing block 303 contacts the inner wall of the closure balloon 301, thereby sealing the inner side of the blood vessel from the inside of the closure balloon 301 and improving the vascular closure capability of the closure balloon 301.

[0026] The outer sheath 1 includes a round tube 101 and a tapered tube 102. One end of the round tube 101 is provided with the tapered tube 102, and the closure device 3 is located inside the tapered tube 102. This arrangement facilitates the insertion of the outer sheath 1 into the sheath tube.

[0027] The built-in occlusion block 303 has a through hole 6 at its center, and the built-in occlusion block 303 is movably connected to the built-in tube 2 through the through hole 6. This configuration makes the movement of the built-in occlusion block 303 directional, enabling it to move in a directional manner to block and close blood vessels.

[0028] The inner wall of the closed balloon 301 is provided with a flexible reinforcing sheet 7, and at least two sets of the flexible reinforcing sheet 7 are provided. The intermediate balloon 302 is provided with a first outlet 8. The first outlet 8 is provided so that the closed balloon 301 expands after the gas overflows. By providing the flexible reinforcing sheet 7, the structural strength of the closed balloon 301 and the stability of the closed blood vessel by the closed balloon 301 can be improved.

[0029] The outer plug assembly 5 includes a sheath 501 and a piston plug 502. The sheath 501 is movably mounted on the outer wall of the inner tube 2, and the piston plug 502 is movably mounted inside the sheath 501. The piston plug 502 of this invention is also movably connected to the inner tube 2, allowing it to move along the inner tube 2 when air is injected into the sheath 501.

[0030] The inner tube 2 inside the sheath 501 has a second outlet 9 on its outer wall, which is located above the piston sealing member 502. When the inner tube 2 is inflated, air enters the sheath 501 through the second outlet 9, thus pushing the piston sealing member 502 to move.

[0031] This invention features a closure device 3 at one end of an internal tube 2 and an external plugging component 5 on the internal tube 2. The closure device 3 consists of a closure balloon 301, an intermediate balloon 302, and an internal plugging block 303. Inflating the closure balloon 301 through the internal tube 2 expands the balloon, causing it to block the inner wall of the blood vessel. Inflating the intermediate balloon 302 pushes the internal plugging block 303 to further clamp and block the inner wall of the blood vessel. The piston plugging component 502 of the external plugging component 5 is pushed in and moves after inflation until it blocks the outer wall of the blood vessel. The device can quickly block and close the inner and outer walls of the blood vessel, thereby reducing patient pain and discomfort.
