Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, to a visual double-lumen endotracheal tube adapter that can perform sterile sputum suction. Background Technology

[0002] Double-lumen bifurcation intubation is the primary intubation method in bronchial anesthesia surgery. It effectively achieves lung isolation and one-lung ventilation, and is a crucial supporting technique for minimally invasive thoracic and cardiac surgeries. Visual double-lumen bifurcation intubation facilitates intraoperative positioning of the double-lumen bifurcation tube, enabling precise positioning without the need for traditional bronchoscope guidance. This eliminates the need for bronchoscope intrusion into the airway for positioning, thereby avoiding airway infection problems caused by bronchoscope positioning procedures.

[0003] However, ventilation dysfunction caused by excessive respiratory secretions during surgery remains a significant issue in the clinical use of double-lumen bifurcated tubes. Increased secretions lead to airway obstruction, which in turn increases airway pressure. This not only causes hypoxia in patients but also barotrauma to the lung tissue, resulting in poor prognosis. Therefore, sputum suction is a common procedure in such surgeries. However, traditional sputum suction is an invasive procedure that can easily cause airway infection and affect patient prognosis. To address these issues, a sterile airway management technique for sputum suction is needed to better serve patients. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing double-lumen bifurcated tubes lack a tubing structure for intraoperative suctioning without sputum suction, and the traditional sputum suction method poses an infection risk. In view of the problems of the existing technology, a visual double-lumen endotracheal tube adapter that can perform sterile sputum suction is provided.

[0005] The purpose and effect of this utility model are achieved by the following specific technical means: including a double-lumen bifurcated tube, wherein a connecting hose is sleeved on both ends of the double-lumen bifurcated tube, a three-way valve tube is provided through the connecting hose, and an adapter and a suction interface tube are respectively inserted into the front and rear ends of the three-way valve tube. The dual-lumen bifurcated tube, connecting hose, three-way valve tube, suction interface tube, and adapter are all transparent sterile plastic tubes; Both the adapter tube opening and the suction interface tube opening have plugs that can be assembled and installed. The plug end extends outward to a sleeve seat, and the sleeve seat has a core tube seat. A sterile tube is sleeved between the outside of the sleeve seat and the plug.

[0006] A further preferred embodiment: the three-way valve pipe is a T-shaped pipe, a valve is rotatably mounted on the three-way valve pipe, and a spring seat is sleeved between the three-way valve pipe and the adapter.

[0007] A further preferred embodiment: the adapter has an internally threaded insertion port structure, and the port end of the adapter has a two-section stepped surface.

[0008] A further preferred embodiment: the plug end is a recessed tube head, and a sealing ring is fitted around the outside of the plug end.

[0009] A further preferred embodiment: the sterile tube is a sealed tube bag, and the connection end of the sterile tube and the plug is inserted and limited through the core tube socket.

[0010] A further preferred embodiment: a stepped groove for insertion and matching is formed between the core tube seat and the sleeve seat, and a spring tube connector is formed by extending the core tube seat towards the end of the stepped groove, wherein the spring tube connector is a snap-fit ​​corrugated tube section.

[0011] The beneficial effects of this utility model are: This aseptic suction visual double-lumen bifurcated tube adapter, combined with the double-lumen bifurcated tube structure and the three-way valve in the middle, can realize independent ventilation of the left and right lungs, and independent aseptic suction of the left and right lungs. The three-way valve allows for flexible switching between suction and ventilation modes, facilitating operation. In addition, the three-way valve also eliminates the need for clamps when using ordinary double-lumen bifurcated tubes. The aseptic suction tube is connected to the suction interface tube to provide a sealed environment for aseptic operation of the tubing. During suctioning, the suction tube does not come into contact with the outside world, preventing contamination and providing a safe operating environment for the entire surgical suction process, avoiding respiratory tract infections caused by suctioning. Combined with the visual operation of the double-lumen bifurcated tube, the safety and practicality of this adapter are greatly improved. Attached Figure Description

[0015] To better understand the above-mentioned objectives, features, and advantages of this utility model, the following description is provided in conjunction with the accompanying drawings. Figs. 1-3The present invention will be further described in detail below with specific embodiments. The following embodiments are merely examples for implementing the present invention. It must be noted that the disclosed embodiments do not limit the scope of the present invention. On the contrary, any modifications and refinements made without departing from the scope of the present invention are within the patent protection scope of the present invention.

[0016] A visual double-lumen endotracheal tube adapter for sterile suction includes a double-lumen bifurcation tube 1. Connecting hoses 2 are sleeved on both ends of the double-lumen bifurcation tube 1. A three-way valve tube 3 is installed through the connecting hoses 2. An adapter 5 and a suction interface tube 4 are respectively inserted into the front and rear ends of the three-way valve tube 3. The double-lumen bifurcated tube 1, connecting hose 2, three-way valve tube 3, suction interface tube 4, and adapter 5 are all transparent sterile plastic tubes; Both the adapter 5 and the suction interface tube 4 have plugs 8 that can be assembled and installed. The plug 8 has a sleeve seat 13 extending outward from the end, and the sleeve seat 13 has a core tube seat 10 in the tube compartment. A sterile tube 11 is sleeved between the outside of the sleeve seat 13 and the plug 8. This type of visual double-lumen bifurcated tube adapter for sterile sputum suction mainly uses the end port of the double-lumen bifurcated tube 1 as the access end of the ventilator connection line, and the two adapters 5 connected in sequence by the connecting hose 2 and the three-way valve tube 3 as the access ends of the endotracheal tube, and the other end of the suction interface tube 4 as the access end of the suction tube. The entire adapter adopts a transparent tubing structure to support the visualization operation during the operation. Based on the above, such as Fig. 1 , 3 As shown, the adapter has a tube end for plug 8 to connect to. Depending on the connection end, when connected to adapter 5, the end of plug 8 is sealed and isolated from the connection end of adapter 5 by an external sterile tube 11. The sleeve seat 13 and the core tube seat 10 serve as the catheter locking inlet. The sterile tube 11 seals and protects the sterile environment of the catheter connection end, improving operational safety. At the same time, plug 8 can also serve as a connection socket for suction catheters. The sterile tube 11 covers and seals the suction catheter segment to ensure a sterile environment outside the suction catheter, preventing contamination of the airway by the tubing structure. The connection structure is as follows. Fig. 2 As shown, one end of the suction interface tube 4 is used as the access end of the suction tube, and the other end is used as the access end of the suction device's suction line. This allows the suction operation to be completed during the procedure by connecting the endotracheal tube to the adapter 5 at the other end. This avoids the risk of infection caused by repeated airway intrusion and improves the practicality and safety of the adapter. The three-way valve tube 3 is a T-shaped tube. A valve 6 is rotatably installed on the three-way valve tube 3. A spring tube seat 7 is sleeved between the suction port tube 4 and the adapter 5. The direction of the suction port tube 4 is switched based on the structure of the valve 6 installed on the tube. The three-way valve tube 3 is divided into three ports, namely the three-way valve tube side hole, the three-way valve tube lower hole, and the three-way valve tube upper hole. Each hole of the three-way valve tube corresponds to the directional mark on the valve 6. The connecting hose 2 is connected to the three-way valve tube side hole, the three-way valve tube lower hole is connected to the adapter 5, and the three-way valve tube upper hole is connected to the suction port tube 4. The suction port tube 4 is usually also externally equipped with a rubber sealing cap based on the shape of the tube opening. The sealing cap is used to seal the upper hole of the three-way valve tube. The sealing cap needs to be removed when performing aseptic suction. like Fig. 1 As shown, the adapter 5 has an internally snapped intubation port structure. The intubation end of the adapter 5 has a two-section stepped surface. The two-section stepped surface, combined with the internal snapping combination, ensures that the insertion end of the endotracheal tube and the end of the adapter 5 are internally snapped and matched. The stepped surface structure improves the sealing performance within the intubation port diameter. Based on the above, the plug end of the plug 8 is a recessed tube head, and a sealing ring 9 is fitted on the outside of the plug end of the plug 8. The added sealing ring 9 is to improve the sealing performance of the plug 8 at the recessed edge when it is inserted into the pipeline structure. Furthermore, the sterile tube 11 is a sealed tube bag with a covering, and the connection end of the sterile tube 11 and the plug 8 is inserted and limited through the core tube seat 10. The fixed end of the sterile tube 11 is further limited by the penetration of the core tube seat 10, and the tube wall step of the core tube seat 10 is used to limit the tube opening of the sterile tube 11 and the inner wall of the plug 8, so as to improve the tensile strength of the sterile tube 11 in the entire pipeline direction. Furthermore, a stepped groove for insertion and matching is formed between the core tube seat 10 and the sleeve seat 13, and a spring tube connector 12 extends from the core tube seat 10 to the end of the stepped groove. The spring tube connector 12 is a snap-fit ​​corrugated tube section, such as... Fig. 3 As shown, the reed connector 12 is further used as the snap-fit ​​section of the insertion pipe structure to provide the reed connector 12 with the flexibility to extend and retract the corrugated pipe length for pipe access, thereby improving the tensile strength of the entire connection between the access pipe and the plug 8.

[0017] Working principle: The double-lumen bifurcation tube 1 enables independent ventilation of the left and right lungs. When in use, the main end of the double-lumen bifurcation tube 1 is connected to the threaded tube of the anesthesia machine, while the bifurcation end of the double-lumen bifurcation tube 1 is connected to the connecting hose 2. The connecting hose 2 is connected to the three-way valve tube 3, which has a three-way function. When the three-way valve marking is aligned with the lower hole of the three-way valve tube connected to adapter 5, and the three-way valve marking is aligned with the side hole of the three-way valve tube connected to connecting hose 2, only air can be passed through, not suctioned. When the three-way valve marking is aligned with the lower hole of the three-way valve tube connected to adapter 5, and the three-way valve marking is aligned with the upper hole of the three-way valve tube connected to suction port tube 4, suctioning is possible but ventilation is not possible. When the three-way valve marking side is aligned with the three-way valve tube side hole connected to the connecting hose 2, the three-way valve marking bottom is aligned with the three-way valve tube bottom hole connected to the adapter 5, and the three-way valve marking top is aligned with the three-way valve tube top hole connected to the suction port tube 4, both suctioning and ventilation can be performed. The lower hole of the three-way valve tube is connected to the adapter 5, and the adapter 5 is connected to the double-lumen bifurcated tube to achieve mechanical ventilation. The three-way valve tube is connected to the suction port tube 4. When performing suctioning, the sealing cap needs to be removed. Then, the sterile suction tube can be connected to the sterile suctioning visual double-lumen bifurcated tube adapter through the suction port tube 4 to achieve sterile suctioning.

[0018] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
