[0002] Medical devices, also known as medical instruments, refer to instruments, equipment, appliances, materials or other articles used alone or in combination on the human body, including the required software; their effects on the human body surface and inside the body are not obtained by pharmacological, immunological or metabolic means, but these means may participate and play a certain auxiliary role. Among medical devices, there is a catheter called a double-lumen endotracheal catheter, which is one of the endotracheal catheters and is used for bronchial intubation. Its characteristic is that it can temporarily separate the ventilation of the left and right main bronchi, and can both inhale anesthetic gas through the bilateral lumens, and can also perform anesthesia and ventilation only with the healthy side lumen, and can aspirate the secretions therein at any time.

[0003] The existing double-lumen bronchial catheters on the market have the following problems when in use: Traditional double-lumen bronchial catheters have the problem of a relatively high risk of cross-infection due to incomplete separation of the catheter cavity. When performing a lung isolation operation, the arc design of the existing catheter has insufficient matching with the anatomical structure of the human bronchus, and the position of the catheter needs to be readjusted during the operation, which not only increases the surgical risk but also causes complications such as postoperative throat pain in patients, and it is difficult to achieve precise airway management in the treatment of critically ill patients. Summary of the Invention

[0012] Preferably, the hydrophilic layer is added with polycaprolactone, and the diversion layer is added with PET fibers.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: For the double-lumen bronchial catheter and its manufacturing method, by providing the cuff on the tracheal body, it can ensure good sealing performance of the catheter after being inserted into the bronchus, prevent gas leakage, and improve the anesthesia effect. The design of the guide wire enables the catheter to be smoothly inserted into the bronchus and is not easily deviated from the target position.

Through the settings of the knob 8, the rotating block 9, the binding block 10 and the extension rod 11, it is convenient to fix the double-lumen bronchial catheter, avoid deviation or detachment during the operation, and improve the safety and stability of the operation. The knob 8 and the binding block 10 form a rotating structure. By rotating the knob 8, the rotating block 9 and the binding block 10 can be driven to rotate, so that the angle of the double-lumen bronchial catheter can be adjusted according to the actual situation of the patient, improving the flexibility of use. Two binding blocks 10 are arranged and are symmetrically arranged with respect to the central axis of the trachea body 1. Through the setting of the two binding blocks 10, the stability of the double-lumen bronchial catheter can be further improved. Two extension rods 11 are arranged, and the extension rods 11 are symmetrically arranged with respect to the central axis of the trachea body 1. Through the setting of the extension rods 11, it is convenient to extend the double-lumen bronchial catheter, so that the length of the double-lumen bronchial catheter can be adjusted according to the actual situation of the patient.

[0019] Furthermore, an antibacterial layer 12 is provided on the outer wall of the trachea body 1. A nylon mesh layer 13 is provided on the outer wall of the antibacterial layer 12. A hydrophilic layer 14 is provided on the outer wall of the nylon mesh layer 13. A diversion layer 15 is provided on the outer wall of the hydrophilic layer 14. Through the settings of the antibacterial layer 12, the nylon mesh layer 13, the hydrophilic layer 14, and the diversion layer 15, the antibacterial performance and comfort of the double-lumen bronchial catheter can be improved. The antibacterial layer 12 can effectively inhibit the growth of bacteria, reduce the risk of cross-infection, and ensure the safety of patients. The nylon mesh layer 13 has good air permeability and wear resistance, which can improve the durability of the catheter and the comfort of patients. The hydrophilic layer 14 can enhance the wettability of the catheter surface, reduce the friction with the bronchial wall, and reduce the discomfort of patients. The diversion layer 15 can guide respiratory secretions and excess moisture to flow smoothly along the catheter surface.

[0020] Furthermore, two guide wires 3 are provided. The guide wires 3 are symmetrically arranged with respect to the central axis of the trachea body 1. Through the setting of the guide wires 3, it is convenient to guide the catheter, enabling it to smoothly enter the bronchus, thereby improving the efficiency and accuracy of the operation. At the same time, the two guide wires 3 are symmetrically arranged with respect to the central axis of the trachea body 1, which can maintain the balance of the catheter and avoid deflection or distortion during the operation.

[0021] Furthermore, the knob 8 and the binding block 10 form a rotating structure. Two binding blocks 10 are provided and are symmetrically arranged with respect to the central axis of the trachea body 1. Through the setting of the knob 8, it is convenient for medical staff to adjust the length of the double-lumen bronchial catheter to adapt to the bronchial anatomical structures of different patients, thereby improving the accuracy and safety of the operation. The binding blocks 10 are symmetrically arranged with respect to the central axis of the trachea body 1, which not only improves the stability of the catheter but also makes the catheter more balanced when adjusting the length, avoiding discomfort to patients or an increase in surgical risks caused by improper length adjustment. In addition, this design also facilitates the rapid and accurate operation of the catheter by medical staff during the operation, improving the surgical efficiency.

[0022] Furthermore, two extension rods 11 are provided. The extension rods 11 are symmetrically arranged with respect to the central axis of the trachea body 1. Through the setting of the extension rods 11, it is convenient to adjust the length of the double-lumen bronchial catheter according to the surgical needs to adapt to the anatomical structures and surgical requirements of different patients, thereby improving the adaptability and flexibility of the operation. The extension rods 11 are made of high-strength and corrosion-resistant materials, ensuring their stability and durability during the operation. At the same time, the design of the extension rods 11 enables smooth transitions when they extend or contract, avoiding discomfort or injury to patients caused by sudden changes.

[0023] Furthermore, antibacterial silica gel is added to the antibacterial layer 12, and reinforced nylon mesh is added to the nylon mesh layer 13. Through the setting of the antibacterial layer 12, bacteria growth on the surface of the catheter can be effectively killed or inhibited, reducing the risk of postoperative infection. The use of the reinforced nylon mesh not only improves the strength and wear resistance of the nylon mesh layer 13, but also further enhances its air permeability, enabling the patient to maintain a more comfortable breathing experience during the operation.

[0024] Furthermore, polycaprolactone is added to the hydrophilic layer 14, and PET fibers are added to the diversion layer 15. Through the setting of the hydrophilic layer 14, the hydrophilicity of the catheter surface can be improved, making it easier for the moist secretions to flow along the catheter surface, reducing the accumulation of secretions on the inner wall of the catheter, and lowering the risk of blockage.

[0025] A double-lumen bronchial catheter and its manufacturing method are as follows: S1. Prepare the trachea body 1 and its related components to ensure that the material quality meets the medical-grade standard; S2. Install the cuff 2 on the outer wall of the trachea body 1 to ensure that the cuff 2 can closely fit the trachea body 1 and has good sealing performance; S3. Install the guide wire 3 at one end of the trachea body 1. The guide wire 3 should have good flexibility and guiding properties to facilitate the smooth guiding of the trachea body 1 in the bronchus; S4. Install the temperature sensor 4 inside the trachea body 1 to monitor the temperature in the bronchus in real time and ensure the safety of the operation process; S5. Install the camera connector 6 on the outer wall of the trachea body 1 to facilitate the connection of the endoscope device and observe the internal situation of the bronchus in real time; S6. Open the fixing block 7 on the outer wall of the trachea body 1 for fixing and connecting the knob 8; S7. Conduct a comprehensive inspection of the trachea body 1 and its components to ensure that all components are correctly installed and functioning properly, and then perform disinfection treatment to meet the clinical use requirements.

[0026] First, prepare the raw materials required for manufacturing the double-lumen bronchial catheter, including but not limited to high-quality medical-grade plastic or silicone materials for the tracheal body 1, and specific materials for components such as the cuff 2, guide wire 3, temperature sensor 4, etc. Then, perform the forming process of the tracheal body 1. Through processes such as injection molding or extrusion, the raw materials are processed into the tracheal body 1 with a preset shape. During this process, it is necessary to ensure that the inner wall of the tracheal body 1 is smooth to reduce the irritation to the bronchus during use. Then, accurately embed electronic components such as the temperature sensor 4 and the camera connector 6 into the predetermined positions of the tracheal body 1 and make electrical connections to ensure that each component can work properly. At the same time, install the cuff 2 on the outer wall of the tracheal body 1. The material of the cuff 2 needs to have good elasticity and sealing performance to ensure that the bronchus can be effectively sealed after being inserted into the bronchus to prevent gas leakage. Next, perform surface treatment on the tracheal body 1, successively coating an antibacterial layer 12, a nylon mesh layer 13, a hydrophilic layer 14, and a drainage layer 15. The layers need to be closely combined to improve the durability and comfort of the catheter. The antibacterial layer 12 can effectively inhibit the growth of bacteria, the nylon mesh layer 13 increases the strength and wear resistance of the catheter, the hydrophilic layer 14 helps to reduce the adhesion of secretions such as sputum, and the drainage layer 15 can guide the secretions to drain smoothly. During the manufacturing process, special treatment is also required for the guide wire 3 to ensure that it is soft and has a certain rigidity to facilitate the flexible operation and positioning of the catheter in the bronchus. Finally, conduct quality inspections on the finished products, including appearance inspection, performance testing, and function verification, etc., to ensure that each double-lumen bronchial catheter meets the design requirements and quality standards.

[0027] Working principle: During use, medical staff first guide the double-lumen bronchial catheter into the patient's bronchus through the guide wire 3. Then, according to the surgical needs, adjust the angle of the catheter by rotating the knob 8 and adjust the length of the catheter through the extension rod 11 to adapt to the bronchial anatomical structures of different patients. The temperature sensor 4 monitors the temperature in the bronchus in real time to ensure the safety of the surgical process. The camera connector 6 is connected to the endoscope device to observe the internal situation of the bronchus in real time, providing a clear surgical field of view for medical staff. The cuff 2 fits tightly against the tracheal body 1 and has good sealing performance to prevent gas leakage. The antibacterial layer 12 effectively inhibits the growth of bacteria and reduces the risk of cross-infection. The nylon mesh layer 13 increases the strength and wear resistance of the catheter, the hydrophilic layer 14 reduces the adhesion of secretions such as sputum, and the drainage layer 15 guides the secretions to drain smoothly. The design of this double-lumen bronchial catheter is reasonable and the manufacturing process is exquisite, which not only improves the accuracy and safety of the surgery, but also reduces the postoperative discomfort of the patient.
