Description

Technical Field

[0001] This utility model relates to the field of drainage tube technology, specifically a drainage tube with a locking structure. Background Technology

[0002] A drainage tube is a medical device used in clinical surgical drainage to guide pus, blood, and fluid accumulated between body tissues or in body cavities to the outside of the body, preventing postoperative infection and promoting wound healing. There are many types of surgical drainage tubes used clinically; some are used for urinary catheterization, others for wounds, and they are used in the thoracic cavity, brain cavity, gastrointestinal tract, and biliary tract, among others. Surgical drainage aims to guide pus, blood, and fluid accumulated between body tissues or in body cavities to the outside of the body, preventing postoperative infection and affecting wound healing. The drainage tube is generally connected to the end of a urinary catheter. To prevent patients from unconsciously pulling the drainage tube off the urinary catheter, a locking mechanism has been developed.

[0003] As disclosed in the authorization announcement number CN219050007U, a drainage tube with a fixed structure includes a main fixing plate. A threaded block is fixedly connected to the upper surface of the main fixing plate. A telescopic support rod is threadedly connected to the inner wall of the threaded block. Fixing devices are fixedly connected to the top and bottom of the surface of the telescopic support rod. A hook is fixedly connected to the upper surface of the telescopic support rod. A drainage bag is attached to the upper surface of the hook. An air bladder is fixedly connected to the upper surface of the drainage bag. A drainage tube is fixedly connected to the lower surface of the drainage bag. A puncture needle is fixedly connected to one end of the drainage tube.

[0004] Although it achieves the drainage tube with a fixed structure, through the setting of a fixing device, telescopic support rod and other structures, the fixing device is fixed on the telescopic support rod, the second connecting rod is pushed inward, so that the rubber arc block presses against the drainage tube, and at the same time the second fixing block slides on the first fixing block to prevent it from bending. While fixing the drainage tube, it can also allow it to drain normally.

[0005] However, this does not solve the problem that the existing drainage tubes are not convenient for modular assembly and disassembly, nor are they easy to lock in multiple ways, which affects the strength of the structure and the effectiveness of preventing detachment. Utility Model Content

[0006] The purpose of this utility model is to provide a drainage tube with a locking structure to solve the problems mentioned in the background art, such as the drainage tube being inconvenient to modularly disassemble and assemble, the drainage tube being difficult to lock in multiple ways, and the impact on the strength of the structure and the anti-loosening effect.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a drainage tube with a locking structure, comprising a connecting tube and a urinary catheter, wherein a urinary catheter is installed at one end of the connecting tube, and an insertion tube is provided at the other end of the connecting tube; a tapered tube is installed at the end of the insertion tube near the connecting tube, and the tapered tube can be inserted into the interior of the connecting tube; a drainage tube is installed at the end of the insertion tube away from the tapered tube; a urine collection bag is installed at the end of the drainage tube away from the insertion tube; a nut is provided on the outer surface of the insertion tube, and the nut is slidably connected to the insertion tube, and an internal thread is provided on the inner wall of the nut; an external thread is provided on the outer wall of the connecting tube on one side of the tapered tube, and the external thread is threadedly connected to the internal thread.

[0008] Preferably, the surface of the connecting tube is provided with a label, and the label is connected to the connecting tube by a snap fastener.

[0009] Preferably, a sleeve is provided on the surface of the connecting tube on one side of the label, and the sleeve is fixedly connected to the connecting tube.

[0010] Preferably, the sleeve has three sets of equally spaced jaws inside, and each jaw has a movable shaft installed on its side wall, and the jaws are movably connected to the sleeve through the movable shafts.

[0011] Preferably, a spring is installed at one end of each claw, and the spring is connected to the sleeve.

[0012] Preferably, a slip ring is provided on the outer wall of the sleeve, and the slip ring is slidably connected to the sleeve and to the chuck.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the drainage tube not only realizes convenient modular disassembly and assembly, and facilitates multiple locking of the drainage tube, but also increases the structural robustness and improves the anti-detachment effect;

[0014] (1) First, slide the slip ring to the left. The slip ring slides on the surface of the sleeve. Under the sliding engagement of the slip ring and the chuck, the slip ring drives the chuck to rotate around the movable shaft and squeeze the spring to open the three sets of chucks. Then, take out the insertion tube. The insertion tube drives the tapered tube to move and insert into the inside of the connecting tube. Then, screw the nut on the external thread. The nut moves on the surface of the external thread. The nut drives the tapered tube to continuously squeeze into the inside of the connecting tube. Because the tapered tube is a conical design, under the continuous squeezing of the nut, a sealing connection is completed between the tapered tube and the external thread. Then, slide the slip ring to the right. The slip ring returns to its original position, and the chuck is no longer under external pressure. Under the action of elasticity, the spring drives the claws to rotate around the movable shaft and then reset, so that the three sets of claws lock onto the protruding part of the insertion tube, thereby locking the insertion tube and the connecting tube together to prevent the insertion tube from falling off the connecting tube. When quick disassembly is required, the above operation is repeated in reverse to complete the quick disassembly and assembly. Then, connect the drainage tube and urine collection bag to the insertion tube, connect the urine catheter to the connecting tube, and install the label on the connecting tube with a snap fastener. The drainage tube can then be used. This achieves convenient modular disassembly and assembly, facilitates multiple locking of the drainage tube, increases the structural strength, and improves the anti-dislodgement effect.

[0021] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0022] Please see Figure 1-5 An embodiment of this utility model provides a drainage tube with a locking structure, including a connecting tube 2 and a urinary catheter 1. The urinary catheter 1 is installed at one end of the connecting tube 2, and the insertion tube 4 is provided at the other end of the connecting tube 2. A tapered tube 11 is installed at the end of the insertion tube 4 near the connecting tube 2, and the tapered tube 11 can be inserted into the interior of the connecting tube 2. A drainage tube 5 is installed at the end of the insertion tube 4 away from the tapered tube 11. A urine collection bag 6 is installed at the end of the drainage tube 5 away from the insertion tube 4. A nut 12 is provided on the outer surface of the insertion tube 4, and the nut 12 is slidably connected to the insertion tube 4. An internal thread 13 is provided on the inner wall of the nut 12. An external thread 10 is provided on the outer wall of the connecting tube 2 on one side of the tapered tube 11, and the external thread 10 is threadedly connected to the internal thread 13.

[0023] A label 3 is provided on the surface of the connecting tube 2, and the label 3 is connected to the connecting tube 2 by a snap fastener;

[0024] A sleeve 7 is provided on the surface of the connecting tube 2 on one side of label 3, and the sleeve 7 is fixedly connected to the connecting tube 2;

[0025] The sleeve 7 has three sets of equally spaced claws 9 inside. Each claw 9 has a movable shaft 15 installed on its side wall, and the claws 9 are movably connected to the sleeve 7 through the movable shaft 15.

[0026] Each of the claws 9 is equipped with a spring 14, and the spring 14 is connected to the sleeve 7;

[0027] A slip ring 8 is provided on the outer wall of the sleeve 7, and the slip ring 8 is slidably connected to the sleeve 7, and the slip ring 8 is slidably connected to the pawl 9;

[0028] First, slide the slip ring 8 to the left. The slip ring 8 slides on the surface of the sleeve 7. Under the sliding engagement of the slip ring 8 and the pawl 9, the slip ring 8 drives the pawl 9 to rotate around the movable shaft 15, causing the pawl 9 to squeeze the spring 14, thereby opening the three sets of pawl 9. Then, take out the insertion tube 4. The insertion tube 4 drives the tapered tube 11 to move and insert into the interior of the connecting tube 2. Then, screw the nut 12 onto the external thread 10. Under the threaded connection between the external thread 10 and the internal thread 13, the nut 12 moves on the surface of the external thread 10. The nut 12 drives the tapered tube 11 to continuously squeeze into the interior of the connecting tube 2. Because the tapered tube 11 is a conical design, the continuous squeezing of the nut 12 completes the sealing connection between the tapered tube 11 and the external thread 10. Then, slide the slip ring 8 to the right. After resetting, the claws 9 are no longer subjected to external pressure. Under the elastic action of the spring 14, the spring 14 drives the claws 9 to rotate around the movable shaft 15 and reset, so that the three sets of claws 9 are locked onto the protruding part of the insertion tube 4, thereby locking the insertion tube 4 and the connecting tube 2 together to prevent the insertion tube 4 from falling off the connecting tube 2. When quick disassembly is required, the above operation is repeated in reverse to complete the quick disassembly and assembly work. Then, the drainage tube 5 and the urine collection bag 6 are connected to the insertion tube 4, the urine catheter 1 is connected to the connecting tube 2, and the label 3 is installed on the connecting tube 2 with a snap fastener. The use of the drainage tube is then completed, realizing convenient modular disassembly and assembly, facilitating multiple locking of the drainage tube, increasing the structural strength, and improving the anti-dislodgement effect.

[0029] Working principle: First, slide the slip ring 8 to the left. The slip ring 8 slides on the surface of the sleeve 7. Under the sliding engagement of the slip ring 8 and the pawl 9, the slip ring 8 drives the pawl 9 to rotate around the movable shaft 15, causing the pawl 9 to squeeze the spring 14, thereby opening the three sets of pawl 9. Then, take out the insertion tube 4. The insertion tube 4 drives the tapered tube 11 to move and insert into the interior of the connecting tube 2. Then, screw the nut 12 onto the external thread 10. Under the threaded connection between the external thread 10 and the internal thread 13, the nut 12 moves on the surface of the external thread 10. The nut 12 drives the tapered tube 11 to continuously squeeze into the interior of the connecting tube 2. Because the tapered tube 11 is a conical design, under the continuous squeezing of the nut 12, the tapered tube 11 and the external thread 13 are squeezed together. After the threaded connection 10 is sealed, slide the slip ring 8 to the right. The slip ring 8 returns to its original position, and the claws 9 are no longer under external pressure. Under the elastic action of the spring 14, the spring 14 drives the claws 9 to rotate around the movable shaft 15 and return to their original position, so that the three sets of claws 9 are locked on the protruding part of the insertion tube 4, thereby locking the insertion tube 4 and the connecting tube 2 together to prevent the insertion tube 4 from falling off the connecting tube 2. When quick disassembly is required, repeat the above operation in reverse to complete the quick disassembly and assembly work. Then connect the drainage tube 5 and the urine collection bag 6 to the insertion tube 4, connect the urine catheter 1 to the connecting tube 2, and install the label 3 on the connecting tube 2 with a snap tie to complete the use of the drainage tube.
