Description

Technical Field

[0001] This utility model belongs to the field of drainage tube technology, specifically relating to a surgical negative pressure drainage tube. Background Technology

[0002] Surgical negative pressure drainage is a technique used in surgical treatment to drain abnormal fluids (such as blood, pus, and exudate) or gases from the body. It aims to reduce tissue pressure, control infection, and promote healing. Its purpose is to drain abnormal fluids such as blood, pus, and digestive juices, reduce the risk of infection, reduce the pressure on local tissues caused by fluid accumulation, avoid secondary damage, and accelerate wound repair by reducing dead space and inflammatory response. Drainage tubes are generally used in the process of negative pressure drainage.

[0003] Currently, existing surgical negative pressure drainage tubes collect the drained fluid through a drainage bottle or bag. Once the bottle or bag is full, it needs to be replaced. However, traditional drainage tubes lack a sealing function, which can easily lead to fluid overflow if the replacement is not handled properly. This hinders the collection of the fluid and can also pollute the surrounding environment. Therefore, we propose a surgical negative pressure drainage tube. Utility Model Content

[0004] The purpose of this invention is to provide a surgical negative pressure drainage tube to solve the existing problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a surgical negative pressure drainage tube, comprising a tube body, a connecting end, and an L-shaped spring plate. One end of the tube body is provided with a connecting end, and a flexible tube is sealed to the end of the connecting end. A stop block is fixedly installed on the outer periphery of the connection between the connecting end and the tube body. Movable grooves are provided on both sides of the inner side of the stop block. An L-shaped spring plate is provided inside each of the two movable grooves. One end of the L-shaped spring plate is placed inside the movable groove and slidably connected thereto. The other end of the L-shaped spring plate extends through the shell of the connecting end to the outside of the flexible tube. The L-shaped spring plate passes through the shell of the connecting end and is slidably connected to the shell of the connecting end.

[0006] Preferably, guide blocks are fixedly installed on both sides of the connection between the hose and the docking end, the guide blocks cover the outside of the hose, and the L-shaped spring sheet extends between the guide block and the hose.

[0007] Preferably, a U-shaped spring sheet is fixedly installed on the inner wall of one side of the movable groove, and the bottom end of the U-shaped spring sheet is in contact with the L-shaped spring sheet.

[0008] Preferably, an extension block is slidably provided at the opening of the movable groove, one end of the extension block extends to the outside of the movable groove, and the other end of the extension block is fixedly connected to an L-shaped spring sheet.

[0009] Preferably, the mating end is provided with mating threads on its exterior, and the mating threads extend to both ends of the mating end.

[0010] Preferably, one end of the tube is provided with an insertion end, which is located at the end of the tube away from the docking end.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. By setting a connecting end, a stop block, and a hose at one end of the tube body, the return spring force at the bottom of the L-shaped spring plate extends to both sides of the hose. The return spring force of the L-shaped spring plate clamps the hose, thereby achieving the sealing of the hose. In conjunction with the extension block, the L-shaped spring plate is driven to extend and retract, so that the opening and closing of the hose can be controlled during the disassembly and assembly of the connecting end. This prevents the overflow of drainage fluid when changing the drainage bottle or drainage bag.

[0013] 2. By setting a U-shaped spring plate inside the movable groove, the function of pushing the L-shaped spring plate and the extension block to reset is realized. After the connection between the docking end and the drainage bottle or drainage bag is disassembled, the L-shaped spring plate can quickly reset and clamp the hose, thereby achieving the purpose of rapid sealing and avoiding over-sealing, which would cause the drainage liquid to drip.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-3 This utility model provides a surgical negative pressure drainage tube technical solution: including a tube body 1, a docking end 3, and an L-shaped spring plate 7. One end of the tube body 1 is provided with a docking end 3, and the end of the docking end 3 is sealed and connected to a flexible tube 5. A stop block 8 is fixedly installed on the outer periphery of the connection between the docking end 3 and the tube body 1. Movable grooves 10 are opened on both sides of the inside of the stop block 8. An L-shaped spring plate 7 is provided inside the two movable grooves 10. One end of the L-shaped spring plate 7 is placed inside the movable groove 10 and slidably connected thereto. The other end of the L-shaped spring plate 7 extends through the shell of the docking end 3 to the outside of the flexible tube 5. The L-shaped spring plate 7 passes through the shell of the docking end 3 and is slidably connected to the shell of the docking end 3.

[0020] Specifically, guide blocks 6 are fixedly installed on both sides of the connection between the hose 5 and the docking end 3. The guide blocks 6 cover the outside of the hose 5, and the L-shaped spring sheet 7 extends between the guide block 6 and the hose 5.

[0021] Specifically, a U-shaped spring plate 11 is fixedly installed on the inner wall of one side of the movable groove 10, and the bottom end of the U-shaped spring plate 11 contacts the L-shaped spring plate 7.

[0022] Specifically, an extension block 9 is slidably provided at the opening of the movable groove 10. One end of the extension block 9 extends to the outside of the movable groove 10, and the other end of the extension block 9 is fixedly connected to the L-shaped spring sheet 7.

[0023] Specifically, the mating end 3 is provided with mating threads 4 on its exterior, which extend to both ends of the mating end 3.

[0024] Specifically, one end of the tube body 1 is provided with an insertion end 2, which is located at the end of the tube body 1 away from the docking end 3.

[0025] In this implementation scheme, under normal conditions, the bottom end of the extension block 9 extends mostly to the outside of the movable groove 10, and the bottom ends of the two L-shaped spring plates 7, under their own restoring elastic force, squeeze the hose 5 from both sides of the hose 5, so that the hose 5 is in a closed state. During use, the connecting thread 4 on the outer periphery of the connecting end 3 is threadedly connected to the internal thread at the opening of the drainage bottle or drainage bag, ensuring the sealing and stability of the connection between the connecting end 3 of the tube body 1 and the drainage bottle or drainage bag. During the connection process, the bottle mouth of the drainage bottle or the bag mouth of the drainage bag gradually moves closer to the stop block 8, and during this process, the extension block 9 is gradually pushed into the interior of the movable groove 10, so that the extension block 9 drives the upper end of the L-shaped spring plate 7 to move into the interior of the movable groove 10, so that the lower end of the L-shaped spring plate 7... The L-shaped spring plate 7 gradually retracts into the housing of the docking end 3, thereby removing the pressure on the bottom of the tubing 5 and opening the passage in the tubing 5. At this time, the tubing 5 is inside the drainage bottle or drainage bag. In this state, the top of the L-shaped spring plate 7 is compressed by the extension block 9, causing it to deform. After the drainage bottle or drainage bag is full, the connection between the docking end 3 and the drainage bottle or drainage bag is removed, causing the extension block 9 to compress it. Under the action of the U-shaped spring plate 11, the L-shaped spring plate 7 is pushed downward to reset, so that the L-shaped spring plate 7 extends to the outside of the tubing 5 again. Under the action of the restoring elasticity, it compresses both sides of the tubing 5, thereby sealing the tubing 5 and preventing the drainage fluid from overflowing.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
