Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical devices, specifically a disposable multipurpose drainage tube that can be used for pneumothorax drainage, as well as for drainage of pus, blood, and fluid accumulated in body tissues or cavities such as the abdominal cavity, brain cavity, gastrointestinal tract, and bile duct. Background Technology
[0002] Disposable drainage tubes are common medical devices with drainage or venting functions. They are frequently used in surgery to drain fluid, blood, or gas around wounds, preventing local infection and other complications. However, most existing disposable drainage tubes are straight tubes, making it difficult to adjust the drainage volume according to the patient's condition, resulting in low drainage efficiency. For example, in patients with pleural effusion or ascites, especially in the late stages of the disease, with a large amount of ascites in the thoracic and abdominal cavities, adding too many drainage tubes can increase the risk of postoperative ascites and infection, while also increasing the difficulty of management and nursing care. Therefore, current technology cannot assemble and disassemble multiple drainage tubes according to drainage needs, making it difficult to achieve multi-channel drainage operations, resulting in low practicality and flexibility. Utility Model Content
[0003] The purpose of this invention is to provide a disposable multi-purpose drainage tube to solve the problems mentioned in the background art, such as the inconvenience of adjusting the drainage volume according to the patient's condition, low drainage efficiency, and low practicality and flexibility.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a disposable multipurpose drainage tube, including a disposable drainage tube body, and further including a forked support head, an external thread, a connecting branch pipe, a sealing component, an auxiliary component, and an adjusting component; a forked support head is fixed to one side of the end of the disposable drainage tube body, the surface of the forked support head is provided with an external thread, the surface of the external thread is connected to the connecting branch pipe, the inner side of the forked support head is connected to the sealing component, the inner side of the connecting branch pipe is connected to the auxiliary component, and the upper end of the connecting branch pipe is provided with an adjusting component.
[0005] As a preferred embodiment, the sealing component enables automatic sealing of the end of the bifurcated branch, the auxiliary component facilitates automatic connection after assembly of the connecting branch tube, and the adjustment component allows for adjustment of the drainage channel flow rate according to treatment needs.
[0006] As a preferred design, the main body of the drainage tube and the opening of the connecting branch tube gradually narrow and taper along the drainage direction. This reduces the backflow of external gas and / or liquid into the drainage tube.
[0007] As a preferred embodiment, the connecting branch pipe is equipped with a unidirectional drainage structure, which is a duckbill-shaped elastic valve formed by one or more interlocking elastic valves. The elastic valves protrude in the drainage direction, and the protruding ends have openings with their edges abutting each other. The unidirectional drainage structure has an outer contour adapted to the inner wall of the connecting branch pipe for installation within the connecting branch pipe. Its advantage is that it can achieve unidirectional drainage and avoid backflow: when accumulated gas or liquid flows to the unidirectional drainage structure, under the action of pressure, the abutting part of the elastic valve opening is forced open, and the gas or liquid to be drained is flushed out through the abutting part of the valve. Conversely, when no gas or liquid flows out, or when the pressure in the drainage direction is less than the pressure in the opposite direction (assuming the drainage direction is the positive direction and the opposite direction is the negative direction), the elastic valve closes due to its own elasticity, thereby achieving the unidirectional drainage function.
[0008] As a preferred embodiment, the sealing assembly includes a connecting port and a sealing plug. One end of the forked branch has a connecting port, and the inner side of the connecting port is connected to the sealing plug. The sealing plug is engaged with the connecting port. By inserting the sealing plug into the connecting port, it is easy to achieve port sealing when assembling and connecting the branch pipe, thereby realizing straight pipe drainage and drainage flow control.
[0009] As a preferred embodiment, the sealing assembly also includes a slider and a slide rail. The slider is fixed to the surface of the sealing plug, and the slider is slidably connected to the slide rail. The slide rail is located inside the bifurcated support. By sliding the slider up and down in the slide rail, the sealing plug can move stably in a directional manner, thus playing a guiding role.
[0010] As a preferred embodiment, the sealing assembly also includes a spring. A spring is installed on the inner side of the slide rail. The spring is symmetrically arranged about the center line of the bifurcated support head. Through the deformation of the spring, the sealing plug can be automatically reset after the position is adjusted.
[0011] Preferably, the auxiliary components include a support frame, an extension rod, and a top plate. The support frame is fixed to the inside of the connecting branch pipe, the extension rod is fixed to the left side of the support frame, and the top plate is fixed to the left end of the extension rod. When the connecting branch pipe is assembled onto the bifurcated support head, the top plate can push the sealing plug upward to facilitate opening the communication port.
[0012] Preferably, the adjustment assembly includes an internally threaded post and an adjustment rod. The upper end of the connecting branch pipe is provided with an internally threaded post, and the inner side of the internally threaded post is connected to the adjustment rod. The adjustment rod is threadedly connected to the internally threaded post. By rotating the adjustment rod in the internally threaded post, the height of the movable plug can be changed, so as to adjust the flow rate of the drainage channel.
[0013] Preferably, the adjustment assembly also includes a movable plug and an adjustment cavity. The lower end of the adjustment rod is connected to the movable plug, which is rotatably connected to the adjustment rod. An adjustment cavity is provided on the outer side of the movable plug. The end of the adjustment rod rotates within the movable plug so that it does not rotate in any direction during the lifting and lowering process, thereby achieving translation.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] 1. This disposable multi-purpose drainage tube features an automatic sealing component to the ends of the bifurcated branches, an auxiliary component for easy assembly and connection of branch tubes, and an adjustment component to allow for flow rate adjustment according to treatment needs. Compared to traditional drainage methods, this drainage tube adopts an assembled Y-shaped pipe structure, which not only facilitates multi-channel drainage operations and quick connection or disassembly of different parts of the drainage tube, but also has a flow rate adjustment function to adapt to different drainage needs and operating environments, improving drainage efficiency and broadening its application range and uses. It can be used for pneumothorax drainage, as well as for drainage of pus, blood, and fluid accumulated in the abdominal cavity, brain cavity, gastrointestinal tract, bile duct, and other body tissues or cavities.
[0016] 2. This disposable multi-purpose drainage tube features external threads on the bifurcated support head, facilitating easy disassembly or installation of connecting branch tubes. This allows for quick switching between straight and Y-shaped tubes. Furthermore, the bifurcated support head contains a directionally movable sealing plug. When the connecting branch tube is assembled, the top plate lifts the sealing plug to connect the tubes. Conversely, when the tubes are disassembled, the connection point is blocked, making it very convenient to use. Attached Figure Description

Detailed Implementation
[0023] In the description of this utility model, for the convenience of explaining this patent, the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings.
[0024] like Figure 1-3 As shown, this utility model provides a technical solution: a disposable multi-purpose drainage tube, including a disposable drainage tube body 1, and further including a bifurcated support head 2, an external thread 3, a connecting branch tube 4, a sealing component 5, an auxiliary component 6, and an adjusting component 7; a bifurcated support head 2 is fixed to one side of the end of the disposable drainage tube body 1, the surface of the bifurcated support head 2 is provided with an external thread 3, the surface of the external thread 3 is connected to the connecting branch tube 4, the inner side of the bifurcated support head 2 is connected to the sealing component 5, the inner side of the connecting branch tube 4 is connected to the auxiliary component 6, and the upper end of the connecting branch tube 4 is provided with an adjusting component 7. The sealing component 5 can automatically seal the end of the bifurcated support head 2, the auxiliary component 6 facilitates automatic connection after assembling the connecting branch tube 4, and the adjusting component 7 facilitates adjustment according to treatment needs. The treatment requires adjusting the flow rate of the drainage channel. The sealing component 5 includes a connecting port 501 and a sealing plug 502. The connecting port 501 is opened at the right end of the bifurcated support 2. The sealing plug 502 is connected to the inner side of the connecting port 501. The sealing plug 502 is engaged with the connecting port 501. By inserting the sealing plug 502 into the connecting port 501, it is easy to achieve port sealing when assembling the connecting branch pipe 4, thereby realizing straight pipe drainage. The sealing component 5 also includes a slider 503 and a slide rail 504. The slider 503 is fixed on the surface of the sealing plug 502. The slider 503 is slidably connected to the slide rail 504. The slide rail 504 is set inside the bifurcated support 2. By sliding the slider 503 up and down in the slide rail 504, the sealing plug 502 can move stably in a directional direction, playing a guiding role.
[0025] like Figure 3-4As shown, in this embodiment, the sealing assembly 5 also includes a spring 505. A spring 505 is installed on the inner side of the slide rail 504. The spring 505 is symmetrically arranged about the center line of the bifurcated support head 2. The deformation of the spring 505 facilitates the automatic reset of the sealing plug 502 after adjustment. The auxiliary assembly 6 includes a support frame 601, an extension rod 602, and a top plate 603. The support frame 601 is fixed to the inner side of the connecting branch pipe 4. An extension rod 602 is fixed to the left side of the support frame 601, and a top plate 603 is fixed to the left end of the extension rod 602. When the connecting branch pipe 4 is assembled onto the bifurcated support head 2, the top plate 603 can push the sealing plug 502 upwards, facilitating the opening of the communication port 501. The adjusting assembly 7 includes an internally threaded post 70. 1. Adjusting rod 702: The upper end of the connecting branch pipe 4 is provided with an internally threaded post 701. The inner side of the internally threaded post 701 is connected to the adjusting rod 702. The adjusting rod 702 is threadedly connected to the internally threaded post 701. By rotating the adjusting rod 702 in the internally threaded post 701, the height of the movable plug 703 can be changed, so as to adjust the flow rate of the drainage channel. The adjusting assembly 7 also includes a movable plug 703 and an adjusting cavity 704. The lower end of the adjusting rod 702 is connected to the movable plug 703. The movable plug 703 is rotatably connected to the adjusting rod 702. The outer side of the movable plug 703 is provided with an adjusting cavity 704. By rotating the end of the adjusting rod 702 in the movable plug 703, it can be prevented from rotating in the same direction during the lifting and lowering process, so as to achieve translation.
[0026] When using the disposable multipurpose drainage tube of this technical solution, first grasp the main body 1 of the disposable drainage tube, and then screw the upper end of the connecting branch tube 4 onto the external thread 3 of the forked branch head 2, thereby realizing the assembly of the connecting branch tube 4.
[0027] Simultaneously, during the tightening process, the top plate 603 on the extension rod 602 pushes the sealing plug 502 upward and drives the slider 503 to slide upward in the slide rail 504, causing the spring 505 group to compress, thereby allowing the sealing plug 502 to disengage from the connecting port 501. This enables the pipeline to be connected while the assembly is complete. Finally, the adjusting rod 702 in the internal threaded column 701 can be rotated, and its end can rotate within the movable plug 703, allowing the movable plug 703 to move downward, thereby reducing the space of the adjusting cavity 704 and thus achieving flow regulation.
[0028] Through the above steps, the external thread 3 is used to facilitate the assembly and connection of the branch tube 4. At the same time, the auxiliary component 6 is used to facilitate the opening of the sealing component 5 to achieve connection. Finally, the flow rate of the drainage channel can be adjusted according to the treatment needs through the adjustment component 7 for use.
[0029] like Figure 5As shown, the connecting branch pipe 4 of this utility model is further provided with a one-way drainage structure 8. The one-way drainage structure 8 is a duckbill-shaped elastic valve formed by one or more interlocking elastic valves. The elastic valve protrudes in the drainage direction, and the protruding end has an opening 81, the edges of which abut against each other. The one-way drainage structure has an outer contour adapted to the inner wall of the connecting branch pipe for installation inside the connecting branch pipe. When the accumulated gas or liquid flows to the one-way drainage structure 8, under the action of pressure, the abutting part of the elastic valve opening 81 is forced open, and the gas or liquid to be drained is discharged from the abutting part of the valve opening 81. Conversely, when no gas or liquid flows out, or when the pressure in the drainage direction is less than the pressure in the opposite direction (assuming the drainage direction is the positive direction and the opposite direction is the negative direction), the opening 81 of the elastic valve closes due to its own elasticity, thereby realizing the one-way drainage function.
