Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to a chest drainage tube. Background Technology

[0002] In modern medicine, chest drainage tubes are commonly used medical devices, widely applied for draining pleural effusions, pneumothorax, and other pleural effusions. Through chest drainage tubes, unwanted substances can be drained from the pleural cavity, thereby restoring and maintaining normal lung function, alleviating patient symptoms, and promoting recovery.

[0003] In existing technologies, common chest drainage tubes are typically made of flexible materials and designed to fit insertion into the chest cavity. To prevent slippage during use, they are usually secured to the patient's body surface using methods such as silk sutures.

[0004] However, suturing not only increases patient pain and infection risk, but also makes the chest drainage tube prone to slippage, and its stability and ease of use need to be further improved. Utility Model Content

[0037] In treating conditions such as pneumothorax, pleural effusion, and empyema, chest drainage tubes are typically used to drain air, fluid, or pus from the pleural cavity, thereby alleviating symptoms and promoting recovery. However, current chest drainage tubes generally have several unresolved issues.

[0038] Understandably, placing a chest drainage tube requires piercing the entire thickness of the patient's chest wall, which inevitably damages the blood vessels in the chest wall, causing bleeding. Since there are currently no effective methods for stopping chest wall bleeding, chest wall hemorrhage and hematoma are highly likely to occur after the chest drainage tube is placed. Furthermore, pneumothorax can also enter the subcutaneous tissue through the chest wall opening, causing subcutaneous emphysema.

[0039] Furthermore, after placing the chest drainage tube into the patient's chest cavity, it needs to be secured to prevent slippage. Traditionally, this is done using a pin and suture to fix the tube to the body surface, which is an invasive procedure that increases patient pain and the risk of infection. In addition, when unsuitable sutures are chosen, such as silk sutures, the fixation effect is not ideal, easily leading to slippage of the chest drainage tube. This method also requires skilled suturing techniques and is not very convenient.

[0040] To address the aforementioned technical problems, this application provides a chest drainage tube. Considering that suturing is an invasive procedure that increases patient discomfort and infection risk, this application incorporates a skin adhesion fixation device on the chest drainage tube for secure fixation, achieving non-invasive fixation. Furthermore, recognizing that a single fixation method may not achieve ideal results, this application also includes an anti-slip groove on the chest drainage tube, and the skin adhesion fixation device is movable within the groove's range. This allows for better adaptation to patients of different body types by flexibly adjusting the device's position, improving ease of use. The anti-slip groove also prevents the chest drainage tube from slipping. By incorporating both the skin adhesion fixation device and the anti-slip groove on the chest drainage tube, this application not only reduces patient discomfort and infection risk but also achieves a dual anti-slip effect.

[0041] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0042] Figure 1 This is a schematic diagram of a chest drainage tube provided in an embodiment of this application. Figure 1 As shown, the chest drainage tube provided in this embodiment includes: an insertion section 10, a middle section 20, and an exposed section 30. The insertion section 10 and the exposed section 30 are connected via the middle section 20, and at least a portion of the middle section 20 near the insertion section 10 is used for insertion into the patient's body. The middle section 20 is provided with an anti-slip groove 21 and is also fitted with a skin adhesion fixation device 22, which is movably connected to the anti-slip groove 21.

[0043] For example, when using a chest drainage tube, the insertion section 10 of the chest drainage tube is inserted into the patient's chest cavity to drain accumulated air, fluid, or pus, etc. It may be designed as a flexible material to facilitate insertion into the patient's body and reduce damage to muscle tissue.

[0044] The insertion section 10 and the exposed section 30 of the chest drainage tube are connected by an intermediate section 20, and at least a portion of the intermediate section 20 near the insertion section 10 is used for insertion into the patient's body. Because the intermediate section 20 is provided with multiple anti-slip grooves 21, which increase the friction between the chest drainage tube and surrounding tissues, slippage can be prevented.

[0045] Optionally, the anti-slip groove 21 can be designed in any suitable shape or structure, such as an annular groove, a spiral groove, a sawtooth groove, etc. The embodiments of this application are not limited, and are intended to provide relatively uniform friction to prevent the chest drainage tube from sliding in the body.

[0046] Furthermore, a skin adhesion fixation device 22 is fitted onto the middle section 20 of the chest drainage tube, and the skin adhesion fixation device 22 is movably connected to the anti-slip groove 21. When using the chest drainage tube, the skin adhesion fixation device 22 can be moved on the middle section 20 according to actual needs. After the position is determined, it is then adhered to the patient's skin to fix the position of the chest drainage tube, thereby further increasing the stability of the chest drainage tube in the patient's body.

[0047] For example, the skin adhesion fixation device 22 in this application embodiment is used to stably fix the chest drainage tube to the patient's skin in a non-invasive manner to prevent it from moving or slipping. The structure of the skin adhesion fixation device 22 is not limited in this application embodiment.

[0048] The exposed section 30 of the chest drainage tube is located outside the patient's body and is used to connect a drainage device or collection container to drain air, fluid, or pus accumulated in the patient's chest cavity.

[0049] The chest drainage tube provided in this embodiment has an anti-slip groove 21 and a skin adhesion fixation device 22 simultaneously provided on the middle section 20, and the skin adhesion fixation device 22 is movably connected to the anti-slip groove 21. On the one hand, by flexibly adjusting the position of the skin adhesion fixation device 22, it can better adapt to patients of different body types, making it more convenient to use. Moreover, the skin adhesion fixation device 22 can achieve non-invasive fixation of the chest drainage tube, which reduces patient pain and discomfort and lowers the risk of infection. On the other hand, the anti-slip groove 21 can also prevent the chest drainage tube from slipping. By simultaneously providing the anti-slip groove 21 and the skin adhesion fixation device 22, this application can achieve a double anti-slip effect, improving the fixation stability of the chest drainage tube.

[0050] Alternatively, in one possible embodiment, such as Figure 1 As shown, the skin adhesion fixing device 22 includes a skin adhesive sheet 222 and a fixing buckle 221 that are integrally formed, wherein the fixing buckle 221 is movably connected to the anti-slip groove 21.

[0051] Exemplarily, the skin adhesive patch 222 and the fixing buckle 221 are integrally formed, so that the skin adhesive patch 222 moves with the movement of the fixing buckle 221. The skin adhesive patch 222 can be medical tape or an adhesive patch, etc., and the fixing buckle 221 can be a fixing clip, etc. This application embodiment does not limit the shape and size of the skin adhesive patch 222; the illustration is merely an example.

[0052] For example, Figure 2 This is a schematic diagram of a skin adhesion fixation device provided in an embodiment of this application. Figure 2 As shown, this is a view of the skin adhesion fixation device 22 from the front of the skin adhesive patch 222. The fixing buckle 221 has a circular hollow structure, and the skin adhesive patch 222 is also circular, fitting over the fixing buckle 221. During installation, the chest drainage tube passes through the hollow structure of the fixing buckle 221, so that the fixing buckle 221 fits onto the middle section 20 of the chest drainage tube.

[0053] During use, the position of the fixing buckle 221 on the middle section 20 can be adjusted according to actual needs. After the position is determined, the integrated structure is fixed on the middle section 20 by fixing buckle 221, and then the skin adhesive patch 222 is glued to the patient's skin. In this way, the purpose of fixing the chest drainage tube without trauma can be achieved.

[0054] Alternatively, in one possible embodiment, a drug with anti-inflammatory effects may also be disposed on the skin adhesive patch 222.

[0055] Understandably, since the chest drainage tube is inserted into the patient's chest cavity by piercing the entire thickness of the chest wall, a wound will be present on the patient's body, and the wound site is more prone to inflammation than other areas. To reduce the probability of inflammation, an anti-inflammatory drug can be applied to the skin adhesive patch 222 that adheres to the skin, thereby reducing inflammation and preventing infection.

[0056] Optionally, an anti-inflammatory drug can be placed at all locations of the skin adhesive patch 222, or it can be placed only at the location where it directly contacts the external chest wall incision, near the connection point between the fixing buckle 221 and the skin adhesive patch 222 as shown in the figure (i.e., the cylindrical protrusion in the middle). This application embodiment does not impose any limitations.

[0057] Optionally, to improve breathability and patient comfort, multiple ventilation holes can be provided on the skin adhesive patch 222. More specifically, multiple ventilation holes can be provided near the connection point between the fixing buckle 221 and the skin adhesive patch 222 (as shown in the figure) where they directly contact the external chest wall incision, to improve breathability.

[0058] Optionally, in one possible embodiment, the connection between the intermediate segment 20 and the inserted segment 10 and the exposed segment 30 can be configured as a detachable connection.

[0059] Exemplary examples show that detachable connections can be snap-fit ​​connections, threaded connections, plug-in connections, etc., and this application does not limit the embodiments. Snap-fit ​​connections refer to connections that use snap-fit ​​or locking mechanisms, allowing segments to be connected and separated through simple pressing or rotating actions. Snap-fit ​​connections facilitate quick assembly and disassembly. Threaded connections refer to connections where threads are designed at the connecting ends of each segment, allowing for a tight connection between segments through rotation. Threaded connections provide high connection strength and sealing performance. Plug-in connections refer to connections achieved through insertion and removal, typically used in conjunction with sealing rings to ensure a tight seal at the connection point.

[0060] The detachable design allows medical staff to adjust the length of the chest drainage tube or replace different functional segments according to specific clinical needs, providing greater flexibility. In addition, each segment can be disassembled individually, which facilitates thorough cleaning and disinfection, helping to reduce the risk of infection. Furthermore, if a segment is damaged or malfunctions, it is not necessary to replace the entire drainage tube when it needs to be replaced; that segment can be replaced separately without affecting the use of other parts, reducing medical costs and patient suffering.

[0061] Alternatively, in one possible embodiment, such as Figure 1 As shown, the chest drainage tube also includes: an air bag 40, a trachea 41, and an inflation assembly 42. The air bag 40 is mounted on the insertion section 10, and a first connection port 43 is provided at the connection between the exposed section 30 and the intermediate section 20. One end of the trachea 41 extends into the chest drainage tube through the first connection port 43 and connects to the air bag 40, while the other end of the trachea 41 extends out of the chest drainage tube through the first connection port 43 and connects to the inflation assembly 42.

[0062] Exemplarily, the airbag 40 is an inflatable component disposed on the insertion segment 10 of the chest drainage tube. The trachea 41 is a long, narrow tube, such as... Figure 1 As shown, one end of the trachea 41 extends into the chest drainage tube through the first connection port 43 and is connected to the air bag 40, while the other end extends out of the chest drainage tube through the first connection port 43 and is connected to the inflation assembly 42.

[0063] Optionally, the first connection port 43 can be as follows: Figure 1 As shown, it is set at the connection between the exposed section 30 and the intermediate section 20; in addition, it can also be set at any position of the exposed section 30, and this application embodiment does not limit it. The first connection port 43 allows the trachea 41 to pass through, guiding the trachea 41 from the inside of the chest drainage tube to the outside. When setting it, it is necessary to ensure the sealing of the connection between the first connection port 43 and the trachea 41 to prevent liquid or air leakage.

[0064] The trachea 41 serves as a connection channel between the air bag 40 and the inflation assembly 42, allowing gas to enter and exit. The inflation assembly 42 may include a manual pump, syringe, or automatic inflation device, etc., for controlling the inflation and deflation of the air bag 40, adjusting the degree of inflation of the air bag 40, thereby adjusting the fixation state of the chest drainage tube.

[0065] After the chest drainage tube is placed, when inflation is needed, the inflation assembly 42 can be controlled to inflate the cuff 40 through the trachea 41, causing the cuff 40 to expand and the chest drainage tube to be pulled back appropriately, so that the cuff 40 exerts appropriate pressure on the chest wall. On the one hand, the expansion of the cuff 40 can create a larger contact surface in the body, increasing friction and thus enhancing the fixation of the chest drainage tube, preventing it from slipping or moving. On the other hand, if active bleeding or subcutaneous emphysema occurs after the chest drainage tube is placed, the position of the skin adhesion fixation device 22 can be adjusted to increase the pressure of the cuff 40 on the chest wall, thereby stopping the bleeding or preventing the subcutaneous emphysema from worsening. When it is time to remove the chest drainage tube, the inflation assembly 42 can be controlled to release the gas in the cuff 40 through the trachea 41 to facilitate tube removal.

[0066] Optionally, in one possible embodiment, the inflation assembly 42 includes an electronic control unit (not shown) and an inflation pump (not shown); the electronic control unit is used to control the inflation pump to inflate the airbag 40 with a target amount of gas through the air tube 41.

[0067] For example, in order to accurately control the inflation and deflation of the airbag 40, an inflation assembly 42 with an electronic control unit and an inflation pump can be selected.

[0068] The electronic control unit is the core component of the entire inflation assembly 42. It manages and controls the inflation pump to ensure that the airbag 40 is inflated with the precise amount of gas. Optionally, the electronic control unit may include components such as a microprocessor and a user interface. The microprocessor executes control algorithms to adjust the operation of the inflation pump according to preset parameters or user input. The user interface allows medical personnel to input the target gas volume or other control parameters and displays information such as the current inflation status.

[0069] The air pump is a mechanical device responsible for delivering gas through the air tube 41 to the airbag 40. Under the control of the electronic control unit, the air pump can achieve precise start-stop control, flow regulation and pressure control to ensure that the airbag 40 reaches the required degree of inflation. The air pump can be an electric pump or other types of pumps, and this application embodiment does not limit it.

[0070] By controlling the inflation pump to inflate the airbag 40 with the target amount of gas, the airbag 40 can achieve the required degree of inflation. It should be noted that the target amount of gas refers to the precise amount of gas that the airbag 40 needs to be inflated according to clinical needs or surgical requirements. This amount can be adjusted according to the patient's specific situation to provide better fixation and safety.

[0071] The inflatable component 42 configured in this embodiment includes an electronic control unit and an air pump. Medical staff can set specific inflation parameters and control the air pump to perform corresponding operations to ensure that the airbag 40 reaches the expected inflation state. This not only improves the efficiency and safety of the operation, but also reduces the possibility of human error.

[0072] Alternatively, in one possible embodiment, such as Figure 1 As shown, the chest drainage tube also includes: a drug sac 50, a drug tube 51, and a drug replenishment assembly 52. ​​The drug sac 50 has a drug outlet 54 and is positioned on the insertion section 10. A second connection port 53 is also provided at the connection between the exposed section 30 and the intermediate section 20. One end of the drug tube 51 extends into the chest drainage tube through the second connection port 53 and connects to the drug sac 50, while the other end of the drug tube 51 extends out of the chest drainage tube through the second connection port 53 and connects to the drug replenishment assembly 52.

[0073] For example, the sac 50 is a container for storing medicine, such as Figure 1 As shown, the drug capsule 50 is installed on the insertion section 10 of the chest drainage tube. The drug capsule 50 is provided with a drug outlet 54, through which the drug can be released into the chest cavity. The drug tube 51 is a long and thin tube. One end of the drug tube 51 extends into the chest drainage tube through the second connection port 53 and is connected to the drug capsule 50. The other end extends out of the chest drainage tube through the second connection port 53 and is connected to the drug replenishment component 52.

[0074] Optionally, the second connection port 53 can be as follows: Figure 1 As shown, it is located at the connection between the exposed section 30 and the intermediate section 20; however, it can also be located at any position on the exposed section 30, and this embodiment of the application does not impose any limitations. The second connection port 53 allows the medicine tube 51 to pass through, guiding the medicine tube 51 from the inside of the chest drainage tube to the outside. When setting it, it is necessary to ensure the sealing of the connection between the second connection port 53 and the medicine tube 51 to prevent liquid or air leakage.

[0075] The medication delivery component 52 is located outside the chest drainage tube and can supply medication to the medication capsule 50. Optionally, the medication delivery component 52 may include a medication infusion pump, a medication reservoir, or other types of medication delivery devices, etc., which are not limited in this embodiment. Through the medication delivery component 52, medical personnel can precisely control the amount and timing of medication delivery, ensuring the effectiveness and safety of treatment.

[0076] For example, when active bleeding occurs after the placement of a chest drainage tube, hemostatic drugs can be injected into the drug sac 50 through the drug tube 51 based on the drug replenishment component 52 in order to stop the bleeding as soon as possible.

[0077] The drug capsule 50, drug tube 51, and drug replenishment component 52 can directly deliver drugs into the pleural cavity during the drainage process, providing a local therapeutic effect. This is very beneficial for patients who need local drug treatment and improves the ease of use.

[0078] Optionally, in one possible embodiment, the medication assembly 52 includes a valve-type self-closing rubber fitting (not shown in the figure). The valve-type self-closing rubber fitting is used to seal the medication tube 51.

[0079] For example, the valve-operated self-closing rubber fitting uses a valve and self-closing rubber material to achieve an automatic sealing function. When medication needs to be delivered to the sac 50, the valve can open under pressure to allow the medication to pass through; when delivery stops, the valve can automatically close to prevent medication from flowing out. The self-closing rubber has elasticity and sealing properties, providing an additional sealing effect when the valve is closed. The elasticity of the rubber material allows the fitting to automatically return to a closed state when no external force is applied, achieving the effect of sealing the medication tube.

[0080] The self-closing rubber fitting with a valve not only prevents drug leakage but also prevents outside air or contaminants from entering the patient's chest cavity, while also providing flexible drug delivery capabilities, making it highly practical.

[0081] Alternatively, in one possible embodiment, the sac 50 is located on the side of the airbag 40 facing the middle section 20.

[0082] For example, such as Figure 1 As shown, the drug sac 50 is designed at the proximal end of the airbag 40 and towards the middle section 20, that is, the drug sac 50 is designed to be located on the left side of the airbag 40.

[0083] Understandably, this design brings the sac 50 closer to the bleeding site, allowing the hemostatic agent to quickly reach the bleeding site when it overflows from the outlet 54 of the sac 50, thus achieving a better hemostatic effect.

[0084] Optionally, in one possible embodiment, the intermediate section 20 is a telescopic tube section, which has an anti-slip groove 21 when it is in a compressed state and a smooth tube section when it is in an extended state.

[0085] For example, the intermediate segment 20 can be designed as a telescopic tube to adapt to different operational needs and functional requirements. For instance, after the chest drainage tube is placed in the patient's chest cavity, to prevent accidental slippage, the intermediate segment 20 can be kept compressed, with anti-slip grooves 21 on its surface. These grooves increase friction, preventing accidental slippage of the chest drainage tube within the chest cavity. After treatment, when removing the chest drainage tube from the patient, to reduce patient discomfort, the intermediate segment 20 can be extended. In this extended state, the intermediate segment 20 becomes a smooth tube, reducing friction and allowing the chest drainage tube to be pulled out more smoothly, thus minimizing patient pain.

[0086] In this embodiment, the middle section 20 is designed as a retractable tube section, which enables the chest drainage tube to provide different functional characteristics under different conditions, thereby enhancing the overall performance and ease of use of the chest drainage tube.

[0087] For example, the chest drainage tube of this application embodiment can be used when performing various surgeries on the chest, lungs, mediastinum, etc., or when pleural effusion or pneumothorax occurs due to various reasons. Specifically, medical staff can first place the chest drainage tube in the patient's chest cavity according to the placement specifications; then, they can control the inflation component 42 to inflate the air bag 40, so that the air bag 40 is fully inflated; then, the chest drainage tube is pulled back appropriately so that the air bag 40 provides appropriate pressure to the patient's chest wall; then, the position of the fixing buckle 221 on the skin adhesion fixation device 22 on the anti-slip groove 21 of the middle section 20 is adjusted. After reaching the appropriate position, the skin adhesive patch 222 is used to adhere the patient's skin for fixation, thereby avoiding traumatic fixation of the chest drainage tube; through the air bag 40, the skin adhesion fixation device 22, and the anti-slip groove 21, a triple anti-slip effect can be achieved.

[0088] Furthermore, if active bleeding or subcutaneous emphysema occurs after the placement of the chest drainage tube, on the one hand, the position of the fixing buckle 221 can be adjusted to increase the pressure of the air bag 40 on the patient's chest wall, thereby stopping the bleeding and preventing the subcutaneous emphysema from worsening; on the other hand, hemostasis can also be achieved by injecting an external hemostatic agent into the drug bag 50 through the drug replenishment component 52.

[0089] The chest drainage tube of this embodiment has an anti-slip groove 21 and a skin adhesion fixation device 22 in the middle section 20, and an air bladder 40 in the insertion section 10, with a drug sac 50 integrated on the outer edge of the air bladder 40. Through the proper use of the anti-slip groove 21, the skin adhesion fixation device 22, the air bladder 40, and the drug sac 50, the effects of preventing bleeding, preventing subcutaneous emphysema, non-invasive fixation, and preventing slippage can be achieved.
