Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a drainage tube occluder. Background Technology

[0002] After choledochotomy for stone removal, a T-tube is usually placed for drainage. The T-tube typically needs to be left in the patient's body for at least six weeks, and longer if stones are still found during follow-up examinations. When the T-tube achieves the treatment goals of draining residual stones, restoring bilirubin levels to normal, or completing the first stone removal and awaiting the next stone removal, the drainage tube is usually clamped to allow bile to return to its normal flow path, awaiting the formation of a sinus tract in the common bile duct or a second surgery. Usually, the drainage bag is first raised, and if there is no discomfort after raising it, the drainage tube can be clamped. Current techniques typically use simple clamps to close the drainage tube, or use a rope to tie the drainage tube to achieve blockage. Excess parts of the drainage tube are also cut off to minimize the impact on the patient's daily life.

[0003] However, during follow-up examinations, it is still necessary to insert a cholangioscope through the original drainage tube for examination, requiring the previously clamped drainage tube to be reopened. Sometimes, patients may experience temporary edema, blockage, or excessive bile secretion after the drainage tube is clamped, requiring the drainage to be reopened until recovery and tube insertion. In such cases, simply using clamps or ropes to seal the drainage tube and cutting off the excess tube can make the reopening process inconvenient. At the same time, using clamps or ropes to seal the drainage tube carries the risk of poor sealing effect due to improper operation, leading to bile leakage, wound infection, and other problems. Utility Model Content

[0004] The purpose of this utility model is to provide a drainage tube plugging device that is simple and secure to seal and facilitates secondary re-opening after sealing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A drainage tube occlusion device includes an occlusion tube, with a pair of connecting tubes coaxially arranged at both ends of the occlusion tube, and an expansion plug fitted on the outer side of each connecting tube; a pair of connecting platforms coaxially arranged between the occlusion tube and the two connecting tubes, and an occlusion clamp sandwiched between the pair of connecting platforms; the two open ends of the occlusion clamp are fixedly connected to the two connecting platforms respectively, and the occlusion clamp is held in the middle section of the occlusion tube; the occlusion tube is connected to both connecting tubes.

[0006] Preferably, a pair of connecting platforms are symmetrically provided with connecting protrusions on the inner side of one end, and the two open ends of the sealing clamp are provided with connecting pieces that are integrally connected to the two connecting protrusions respectively.

[0007] Preferably, pull rings are provided at both ends of the opening of the sealing clamp, and the pull rings are located on the outside of the connecting piece.

[0008] Preferably, the sealing tube is a silicone flexible tube, which is in a closed state when clamped by the sealing clamp.

[0009] Preferably, a protective sleeve is fitted on the outside of the connecting pipe, and the inner diameter of the protective sleeve is smaller than the maximum diameter of the expansion plug.

[0010] Preferably, pull tabs are provided at both ends of the opening of the sealing clamp, and the two pull tabs have different lengths.

[0011] Preferably, the expansion plug includes a plurality of frustum-shaped structures arranged in sequence, wherein the outer diameter of the frustum-shaped structures is smaller than the inner diameter.

[0012] The beneficial effects of this utility model are as follows: This invention employs a structure with a built-in sealing clamp and sealing tube. When the drainage tube needs to be sealed, the excess portion of the drainage tube is cut off, and the connecting tube of the sealing device is inserted into the end of the drainage tube to complete the sealing. When drainage needs to be restored after sealing, a new drainage tube is inserted and connected to the connecting tube at the other end. The sealing clamp is then pulled open using the pull ring to restore the drainage tube's flow, achieving rapid and non-damaging restoration. The entire process is simple and requires no professional medical personnel. If a patient develops acute symptoms outside the hospital after the tube has been clamped, the patient can quickly restore the drainage tube themselves, saving more time for timely medical examination.

[0013] This invention effectively maintains the seal between the drainage tube and the external environment during the sealing and recanalization process. During sealing, the protective sleeve isolates the inside of the drainage tube from the external environment, preventing contamination and avoiding the risk of direct communication between the patient's body cavity and the external environment. This application eliminates the need for manual sealing of the drainage tube, as the sealing tube is clamped from the beginning. Simply insert the connecting tube into the drainage tube to connect it, avoiding the risk of poor sealing effect due to improper manual operation. Attached Figure Description

[0016] Example 1 The following is a further explanation of the present invention in conjunction with specific embodiments, such as... Figure 1 and Figure 2 As shown, this embodiment is a drainage tube occluder, which is mainly used to clamp the drainage tube when using T-tube drainage after surgeries such as common bile duct lithotomy; it includes an occluder tube 3, which is made of flexible silicone material, and is soft and elastic; an occluder clip 4 is provided in the middle of the occluder tube 3, which clamps the outside of the occluder tube 3, and can close the occluder tube 3 when closed.

[0017] At both ends of the sealing tube 3, a pair of connecting platforms 2 are respectively provided. The connecting platform 2 is a circular plate structure, and a through hole that mates with the sealing tube 3 is provided at its center; for example Figure 5 As shown, a pair of connecting protrusions 21 are symmetrically arranged on the inner surface of the same end of the two connecting platforms 2. The connecting protrusions 21 are used to connect with the sealing clamp 4. The open end of the sealing clamp 4 is provided with a connecting piece that mates with the connecting protrusions 21. The connecting piece and the connecting protrusions 21 are integrally connected, as shown. Figure 4 As shown; when it is necessary to unlock the sealing clip 4, the connection between the connecting piece 4 and the connecting protrusion 21 can be broken by using the two pull rings 5 ​​at the end of the sealing clip 4, so that the sealing clip 4 is in a free state and the sealing tube 3 is unlocked; under the elastic action of the sealing tube 3 itself, the sealing tube 3, which has lost the restriction of the sealing clip 4, can restore its original cylindrical structure, as shown. Figure 5 As shown.

[0018] like Figure 3 and Figure 4As shown, connecting pipes 6 are connected to the outer surfaces of both connecting platforms 2. The connecting pipes 6 and the sealing pipes 3 are coaxially arranged, and their central through holes are connected to the sealing pipes 3. An expansion plug 1 is fitted on the outer surface of the connecting pipe 6. The expansion plug 1 includes multiple frustum-shaped structures arranged in sequence, and the outer diameter is smaller than the inner diameter. The expansion plug 1 is also made of flexible silicone material and can be inserted into the drainage tube. The sealing device and the drainage tube are fixedly connected by friction. A protective sleeve 7 is provided on the outer side of both expansion plugs 1. The protective sleeve 7 is a barrel-shaped structure with one open end. Its open end allows the connecting pipe 6 and the expansion plug 1 to be inserted and fixed firmly. When not in use, it provides sealing protection for the internal connecting pipe 6 and the sealing pipe 3. When in use, the protective sleeve 7 can be removed to insert the exposed expansion plug 1 into the drainage tube.

[0019] In practical use, this embodiment first uses clamps or ropes to clamp the upper end of the drainage tube, then cuts off the excess drainage tube; then, the protective sleeve 7 at one end of the occluder in this embodiment is removed, exposing the connecting tube 6 and the expansion plug 1 at one end, as shown. Figure 1 As shown; insert the connecting tube 6 and the expansion plug 1 together into the upper drainage tube 8, as shown. Figure 6 As shown, then remove the previously set clips or ropes to complete the sealing of the drainage tube.

[0020] When the drainage tube needs to be reopened, first remove the remaining protective sleeve 7 to expose the connecting tube 6 and expansion plug 1 at the other end. Then, insert the prepared lower drainage tube 9, which is connected to the drainage bag, into the connecting tube 6 and expansion plug 1. At this time, pull the pull ring 5 to both sides to break the connecting piece, which will open the sealing clamp 4 and open the sealing tube 3. This will form a connected drainage channel between the upper drainage tube 8 and the lower drainage tube 9, thus achieving the reopening of the drainage tube.

[0021] Example 2 like Figure 8 As shown, the difference between this embodiment and embodiment 1 is that the opening end of the sealing clip 4 in this embodiment does not use a pull ring 5 structure, but uses a pair of pull tabs 10 of different lengths; the pull tabs 10 can avoid the risk of the pull ring 5 being pulled open due to accidental circumstances. When the sealing clip 4 needs to be opened, a person needs to hold the longer end and pull it outward.

[0022] Example 3 like Figure 9 As shown, the difference between this embodiment and embodiment 2 is that in this embodiment, the end of the sealing clip 4 is connected by a buckle 11 structure, and the connecting protrusion 21 is no longer provided on the connecting platform 2, and the connecting piece is no longer provided on the sealing clip 4, so that the sealing clip 4 and the connecting platform 2 are set independently; when opening the sealing clip 4, the longer end of the buckle 11 is pulled outward to unlock the buckle, and then the sealing clip 4 is unlocked.

[0023] The above description is merely a further explanation of the present utility model in conjunction with specific embodiments. All descriptions made do not imply any limitation on the protection scope of the present utility model. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be determined by the protection scope of the claims.
