Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a dual-lumen endotracheal tube based on dynamic pressure feedback. Background Technology

[0002] Double-lumen endotracheal intubation completely isolates the left and right main bronchi and is currently the most important lung isolation technique, widely used in non-cardiothoracic surgeries such as thoracic surgery, cardiac surgery, and spinal fusion. Double-lumen endotracheal intubation allows for separate ventilation and suction of both lungs, effectively preventing secretions from the affected lung from contaminating the healthy lung; it also allows the operated lung to collapse, facilitating surgical procedures and reducing mechanical damage to the lungs. In life-threatening situations such as severe intrapulmonary hemorrhage, double-lumen endotracheal intubation is also necessary for effective lung isolation to protect the healthy lung and prevent the patient from suffocating.

[0003] However, existing dual-lumen endotracheal intubation systems based on dynamic pressure feedback have the following problems during use: During surgery, when single-lung ventilation is required, manual clamping of one trachea in the Y-connector is typically used. This is not only labor-intensive but also results in insufficient clamping and sealing, leading to cumbersome procedures and potentially affecting intubation effectiveness. Therefore, a corresponding technical solution needs to be designed to address these problems. Utility Model Content

[0004] The purpose of this invention is to provide a dual-lumen endotracheal intubation system based on dynamic pressure feedback. This solves the technical problem that during surgery, when single-lung ventilation is required, it is generally necessary to manually clamp one of the trachea in the Y-connection. This is not only labor-intensive but also results in insufficient clamping and sealing, leading to cumbersome operation that can affect the use of the intubation system. This invention meets the actual needs of use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes a Y-type connector, a dual-lumen endotracheal cannula, a main bronchus, and a secondary bronchus. The Y-type connector has a fixing block, and the fixing block has two symmetrically arranged fixing holes. A connecting tube is arranged in each fixing hole, and a sealing plate is arranged inside the middle of the connecting tube. A rotating post is arranged between the top of the sealing plate and the fixing block. A first sealing ring is arranged on the outer edge of the sealing plate. A second sealing ring is arranged inside the connecting tube at the same position as the sealing plate. A rotating block is arranged on the top of the rotating post, and several positioning protrusions are evenly distributed on the bottom of the rotating block.

[0006] In a preferred embodiment of this utility model, the double-lumen endotracheal cannula is provided with two air bladders, and each of the top ends of the main bronchus and the accessory bronchus is provided with an air tube, and the Y-type connector is inserted into the air tube.

[0007] In a preferred embodiment of this utility model, the middle part of the fixing block has a square structure and the two ends have a rounded curved structure. The two ends of the connecting pipe are located outside the fixing block, and the connecting pipe is fixedly connected to the fixing block.

[0008] In a preferred embodiment of this utility model, the connecting tube is inserted into the Y-type connector, the sealing plate is circular in shape, a column is located between the bottom center of the sealing plate and the inner wall of the connecting tube, and one top end of the rotating column is located outside the fixed block.

[0009] In a preferred embodiment of this utility model, the top end of the rotating column is larger than the middle part, the first sealing ring and the second sealing ring are both made of rubber, and the rotating block is located outside the top of the fixed block.

[0010] In a preferred embodiment of this utility model, the positioning protrusion is generally hemispherical, and the top of the fixing block has several positioning grooves that cooperate with the positioning protrusion. Both the positioning protrusion and the positioning grooves are distributed in a circular position.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: By using components such as fixing blocks and sealing plates, a single tube in the Y-connector can be easily sealed. During surgery, if a single-lung operation is required, sealing can be easily performed without the need for manual clamping, effectively saving manpower. At the same time, the connection between the first and second sealing rings ensures the stability of the seal and the stability of single-lung ventilation, thus solving the problem of cumbersome operation that could affect the use of intubation.

A sealing plate 13 is provided in the middle of the connecting tube 11. A rotating column 10 is provided between the top of the sealing plate 13 and the fixing block 6. A first sealing ring 15 is provided on the outer edge of the sealing plate 13. A second sealing ring 12 is provided inside the connecting tube 11 at the same position as the sealing plate 13. A rotating block 8 is provided on the top of the rotating column 10. Several positioning protrusions 9 are evenly distributed on the bottom of the rotating block 8.

[0016] Further improvements include two cuffs 3 on the double-lumen endotracheal cannula 4, specifically, as follows: Figure 1 As shown, there are two cuff tubes near the top of the double-lumen endotracheal tube 4 for inflating the cuff 3. There is also a connecting tube for connecting to a pressure monitor to achieve pressure feedback of the intubation tube. The top end of the main bronchus 1 and the auxiliary bronchus 2 are both provided with trachea 7, and Y-type connector 5 is inserted into the trachea 7.

[0017] Further improvements include a square structure in the middle of the fixing block 6 and a curved structure at both ends, with the two ends of the connecting pipe 11 located outside the fixing block 6, and the connecting pipe 11 being fixedly connected to the fixing block 6.

[0018] In a further improvement, the connecting tube 11 is inserted into the Y-type connector 5, the sealing plate 13 is circular in shape, and there is a column between the bottom middle of the sealing plate 13 and the inner wall of the connecting tube 11.

Both the positioning protrusion 9 and the positioning grooves are distributed in a circular position.

[0021] In use: First, the main bronchus tube 1 is inserted into the patient's trachea. After being moved to the correct position, the cuff 3 is inflated and fixed through the cuff tube. Then, the Y-type connector 5 is inserted into the connecting tube 11 and connected to the two trachea 7. During use, if one-lung ventilation is required, the rotating block 8 at the corresponding position is rotated, which, together with the rotating column 10, drives the sealing plate 13 to rotate until the first sealing ring 15 on the sealing plate 13 is in complete contact with the second sealing ring 12, thereby sealing the connecting tube 11. There is no need to manually clamp the tube, which is convenient to use and ensures the stability of one-lung ventilation operation.

[0022] This utility model comprises a main bronchus (1), a secondary bronchus (2), a cuff (3), a double-lumen endotracheal cannula (4), a Y-connector (5), a fixing block (6), a trachea (7), a rotating block (8), a positioning protrusion (9), a rotating column (10), a connecting pipe (11), a second sealing ring (12), a sealing plate (13), a fixing hole (14), and a first sealing ring (15).
