Description

Technical Field

[0001] This utility model relates to the field of medical devices, specifically providing a flushing and drainage tube to prevent side leakage. Background Technology

[0002] Irrigation and drainage tubes are used for clinical surgical drainage. During the postoperative recovery process of some abdominal and thoracic surgeries, it is necessary to insert the tube for an extended period to aspirate accumulated fluid to prevent infection and promote wound healing. However, prolonged placement can lead to skin laxity at the insertion site, or unevenness of the skin surface due to disease. Current circular balloons cannot conform well to the skin surface, failing to maintain a proper seal with the drainage tube, resulting in fluid leakage from the insertion site and causing infection. Furthermore, during use, the drainage tube is prone to misalignment or displacement from the insertion site, leading to drainage failure and affecting patient recovery. Therefore, a more suitable irrigation and drainage tube is needed that can perform irrigation and drainage while ensuring a tight seal and good stability at the insertion site. Summary of the Invention

[0003] To address the aforementioned problems in the existing technology, this utility model provides a flushing and drainage tube to prevent side leakage. The tube includes a drainage tube with three cavities: a main drainage cavity, and two others, an inflation cavity and a flushing cavity. After the front end of the drainage tube passes through the insertion port into the thoracic or abdominal cavity, it is secured by a fixing sleeve in the middle of the tube and a conical balloon to prevent dislodgement. Simultaneously, the upper conical surface of the conical balloon fits tightly against the inner surface of the skin, ensuring a tight seal at the insertion port. If the insertion port becomes loose or leaks, the drainage tube can be pulled out a suitable distance to allow the upper conical surface of the conical balloon to re-fit tightly against the inner surface of the skin, maintaining a sealed state.

[0004] The specific technical solution provided by this utility model is as follows: A flushing and drainage tube for preventing side leakage includes a drainage tube with three cavities: a drainage cavity, an inflation cavity, and a flushing cavity. The drainage cavity can be connected to a negative pressure drainage device. An inflation tube is connected to the rear end of the inflation cavity, and a flushing tube is connected to the rear end of the flushing cavity. A fixing sleeve and a conical balloon are provided in the middle of the drainage tube to fix it. A flushing hole and a drainage hole are provided on the front side wall of the drainage tube.

[0005] Furthermore, the upper and lower openings of the inflation cavity and the upper opening of the flushing cavity are all sealed with sealant, which is placed into the curing unit during product assembly before leaving the factory.

[0006] Furthermore, both the inflation tube and the flushing tube are equipped with one-way valves to prevent backflow of gas or liquid in the pipeline, which could cause infection.

[0007] Furthermore, the fixing sleeve is fitted onto the drainage tube and can slide up and down to adjust its position. The fixing sleeve has buckles on the outside to secure it to the drainage tube. Even further, the fixing sleeve has ventilation holes on its surface to prevent prolonged contact with the skin and potential damage.

[0008] Furthermore, the conical balloon is equipped with a balloon ventilation port that communicates with the inflation cavity, allowing the balloon to be inflated or infused with saline solution via the inflation tube. When inflated, the thick upper wall of the conical balloon causes the lower part to inflate, while the upper part forms a cone shape, allowing for better contact with the inner surface of the skin to form a sealed space. This, combined with the fixing sleeve, secures the drainage tube and prevents it from dislodging. If the insertion port becomes loose or leaks, simply pulling the drainage tube out a suitable distance will allow the upper conical surface of the balloon to re-adhere tightly to the inner surface of the skin, thus maintaining a sealed state.

[0009] Furthermore, the front end sidewall of the drainage tube is provided with several flushing holes and drainage holes, the flushing holes are connected to the flushing cavity, and the drainage holes are connected to the drainage cavity.

[0010] Compared with the prior art, the present invention has achieved the following technical effects: (1) The upper and lower openings of the air-filled cavity of the drainage tube and the upper opening of the flushing cavity are all sealed with sealant to prevent flushing fluid or accumulated fluid from entering the air-filled cavity and to ensure the sealing of the drainage tube.

[0011] (2) The drainage tube is equipped with a fixing sleeve and a balloon in the middle to fix the drainage tube, preventing the drainage tube from shifting or falling off the skin. No suturing or suture removal is required, and disassembly is convenient. The fixing sleeve is a sleeve-type design that can slide up and down to adjust its position. The balloon has a conical structure, and the upper conical surface can better fit the inner surface of the skin. When the insertion port becomes loose or leaks, the drainage tube can be pulled out a suitable distance to allow the upper conical surface of the conical balloon to re-fit tightly with the inner surface of the skin, thereby maintaining a sealed state and improving the flexibility of use.

[0012] (3) The surface of the fixing sleeve has ventilation holes, which avoids long-term coverage of the skin surface and damage to the skin. At the same time, the fixing sleeve is fastened by external buckles, which further improves the stability. Attached Figure Description

Detailed Implementation

[0014] 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 protection scope of this utility model.

[0015] This invention provides a flushing drainage tube to prevent side leakage, such as... Figure 1 As shown, the device includes a drainage tube 1, which has three cavities: a main drainage cavity 1-8, an inflation cavity 1-7, and a flushing cavity 1-9. The drainage cavity 1-8 can be connected to a negative pressure drainage device. The rear end of the inflation cavity 1-7 is connected to an inflation tube 1-3, and the rear end of the flushing cavity 1-9 is connected to a flushing tube 1-2. A fixing sleeve 3 can be fitted onto the middle of the drainage tube 1. A conical balloon is also fixedly installed in the middle of the drainage tube 1. The front side wall of the drainage tube 1 has a flushing hole 1-5 and a drainage hole 1-4.

[0016] The upper and lower openings of the inflation chamber 1-7 and the upper opening of the flushing chamber 1-9 are all sealed with sealant 1-1.

[0017] Both the inflation pipe 1-3 and the flushing pipe 1-2 are equipped with one-way valves 2 to prevent backflow of gas or liquid in the pipes, which could cause infection.

[0018] like Figure 2 As shown, a fixing sleeve 3 is fitted onto the drainage tube 1, which can be slid up and down to adjust its position.

[0019] like Figure 3As shown, the fixing sleeve 3 has a buckle 4 on the outside for fastening the fixing sleeve 3 to the drainage tube 1. Furthermore, the surface of the fixing sleeve 3 has ventilation holes to avoid long-term coverage of the skin surface and damage to the skin.

[0020] like Figure 4 As shown, the conical balloon 6 has a balloon ventilation port 1-6 that communicates with the inflation channel 1-7. The conical balloon 6 is inflated or injected with physiological saline through the inflation tube 1-3. When the conical balloon 6 is inflated, the upper part is thick, causing the lower part to inflate. The upper part is conical, which allows it to better fit with the inner surface of the skin 5-1 to form a sealed space. When the insertion port loosens or there is leakage, the drainage tube 1 can be pulled out a suitable distance to allow the upper conical surface of the conical balloon 6 to re-fit tightly with the inner surface of the skin 5-1, thereby maintaining a sealed state.

[0021] like Figure 5 and Figure 6 As shown, the front end side wall of the drainage tube 1 is provided with several flushing holes 1-5 and drainage holes 1-4. The flushing holes 1-5 are connected to the flushing cavity 1-9, and the drainage holes 1-4 are connected to the drainage cavity 1-8, which can increase the flushing and drainage area.

[0022] The specific implementation method is as follows: Before use, attach the fixing sleeve 3 to the drainage tube 1. The fixing sleeve 3 is made of rubber and can be expanded. Insert the front end of the drainage tube 1 into the abdominal cavity or thoracic cavity so that the upper cone surface of the conical balloon 6 is below the inner skin surface 5-1. Inflate the conical balloon 6 or inject saline through the inflation tube 1-3 to make the upper cone surface of the conical balloon 6 fit tightly against the inner skin surface 5-1. Then adjust the fixing sleeve 3 to fit the skin. Pry the opening handle 4-2 of the buckle 4 outward to separate the connecting teeth 4-3, thereby opening the buckle 4. The buckle 4 covers the middle of the fixing sleeve 3. At the same time, press the first pressing surface 4-1 and the second pressing surface 4-4 with two fingers to make the connecting teeth 4-3 on both sides engage, and then fasten the fixing sleeve 3 to the drainage tube 1 in the appropriate position. Fluid can be injected into the flushing cavity 1-9 through the flushing tube 1-2 and sprayed out from the flushing hole 1-5 on the front side wall of the drainage tube 1 to achieve the purpose of flushing. The drainage cavity 1-8 of the drainage tube 1 is connected to a negative pressure drainage device. Fluid or body fluid enters the drainage cavity 1-8 through the drainage hole 1-4 and is then discharged from the body. During long-term use, if the insertion port becomes loose or leakage occurs, simply pull out the drainage tube 1 a suitable distance to allow the upper conical surface of the conical balloon 6 to re-adhere to the inner surface of the skin 5-1. Loosen the buckle 4 and readjust the position of the fixing sleeve 3 to fix the drainage tube 1 in conjunction with the conical balloon 6.

[0023] As another specific embodiment of this utility model, such as Figure 7As shown, when the diameter of the drainage tube 1 is large, there will be greater resistance during insertion. In this case, the skin can be punctured together with the puncture needle 7 and the dilator tube 8. Then, the puncture needle 7 is pulled out, and the drainage tube 1 is passed through the middle of the dilator tube 7 to facilitate insertion. The dilator tube 8 has a two-part structure with thin walls and a gradually tapering conical shape at the bottom to reduce puncture resistance. The middle diameter can accommodate the drainage tube 1. After the drainage tube 1 is passed through, the dilator tube 8 is pulled upward out of the skin and then separated from the drainage tube 1 by splitting it into two pieces in the middle.

[0024] While the specific embodiments of this utility model have been described in detail above, this utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this utility model. Modifications or variations that do not involve creative labor are still within the protection scope of this utility model.
