Description

Technical Field

[0001] The present invention relates to the field of tracheal catheter devices with an external bronchial occluder, and particularly to a tracheal catheter device with an external bronchial occluder. Background Art

[0002] A tracheal catheter is a medical device inserted into a patient's trachea and / or bronchi to create a temporary artificial respiratory passage for the patient, especially for those who cannot breathe independently. A bronchial occlusion catheter is a disposable medical device used in clinical surgeries, mainly applied to thoracic surgeries that require one-lung ventilation. By occluding one main bronchus, lung isolation is achieved, providing a good surgical field for surgeons. At the same time, it prevents secretions or blood from the operative side lung from entering the healthy side lung, ensuring the patency of the airway of the healthy side lung and avoiding cross-infection.

[0003] However, in traditional operations, when a bronchial occluder is used together with a tracheal catheter, the bronchial occluder is usually placed into the balloon through-hole on the outer side of the tracheal catheter, and then the balloon part of the bronchial occluder is introduced into the bronchus and the balloon is inflated to occlude the bronchus, causing the lung tissue on that side to collapse, facilitating the surgical operation of the surgeon. However, when the bronchial occluder is withdrawn, the through-hole on the outer side balloon of the tracheal catheter is hollow, causing the tracheal catheter to lose its occluding effect and affecting the surgery.

[0004] Therefore, it is necessary to provide a new tracheal catheter device with an external bronchial occluder to solve the above technical problems. Summary of the Invention

[0005] To solve the above technical problems, the present invention provides a tracheal catheter device with an external bronchial occluder that is easy to peel off.

[0006] The tracheal catheter device with an external bronchial occluder provided by the present invention includes a tracheal tube, an external sealing mechanism is arranged on the outer side of the tracheal tube, and a bronchial occlusion tube is inserted into the internal part of the external sealing mechanism. The external sealing mechanism is used to ensure the occluding effect of the tracheal tube when the bronchial occlusion tube is externally connected to the outer side of the tracheal tube.

[0007] In order to achieve the effect of easily making the inner wall of the first balloon contact the outer wall of the bronchial occlusion tube by blowing in gas to maintain the seal, as a tracheal catheter device with an external bronchial occluder provided by the present invention, preferably, the external sealing mechanism includes a first balloon installed on the tracheal tube, a Y-shaped through-hole is opened inside one side of the first balloon, and the bronchial occlusion tube is slidably inserted into the internal part of the Y-shaped through-hole.

[0008] In order to achieve the effect of facilitating the sealing effect even when no bronchial occluder is inserted, the present invention provides a tracheal catheter device with an external bronchial occluder. Preferably, a plurality of elastic silicone flap blocks are connected to the first balloon. A cavity is formed inside the elastic silicone flap block, and an inner valve is connected to one side of the elastic silicone flap block.

[0009] In order to achieve the effect of facilitating the closure of the human tracheal passage in cooperation with the first balloon, the present invention provides a tracheal catheter device with an external bronchial occluder. Preferably, a first air port and a second air port are respectively arranged on the tracheal duct. A second balloon is arranged on the tracheal duct. The air outlet end of the first air port is communicated with the inside of the first balloon, and the air outlet end of the second air port is communicated with the inside of the second balloon.

[0010] In order to achieve the effect of facilitating the insertion of other accessories, the present invention provides a tracheal catheter device with an external bronchial occluder. Preferably, a wire routing hole is arranged at one end of the tracheal duct, and a third balloon is arranged on the bronchial occluding tube.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] External sealing mechanism: It is convenient to install the bronchial occluding tube on the outside of the tracheal duct, and the first balloon can cooperate with the third balloon to block the trachea. When the bronchial occluding tube is withdrawn, without the bronchial occluding tube blocking the Y-shaped through hole, the elastic silicone flap block can cooperate with the inner valve to close the Y-shaped through hole, ensuring the sealing effect and the hygiene inside the Y-shaped through hole, avoiding contact between the Y-shaped through hole and the outside and preventing contamination. At the same time, it can also prevent damage caused by sudden ventilation of both lungs when the bronchial occluding tube is removed after a long operation. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation mode

[0018] The present invention will be further described below in conjunction with the accompanying drawings and implementation modes.

[0019] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , where Figure 1 is a schematic structural diagram of a preferred embodiment of the tracheal catheter device for externally placing the bronchial occluder provided by the present invention; Figure 2 is Figure 1 a schematic structural diagram of the tracheal tube shown in Figure 3 is Figure 2 a structural sectional view of the first balloon shown in Figure 4 is Figure 3 an enlarged schematic diagram of the structure at A in . The tracheal catheter device for externally placing the bronchial occluder includes a tracheal tube 1. An external sealing mechanism 3 is arranged on the outer side of the tracheal tube 1. A bronchial occlusion tube 2 is inserted inside the external sealing mechanism 3. The external sealing mechanism 3 is used to ensure the occlusion effect of the tracheal tube 1 when the bronchial occlusion tube 2 is externally connected to the outer side of the tracheal tube 1.

[0020] In the specific implementation process, as shown in Figure 3 and Figure 4 , the external sealing mechanism 3 includes a first balloon 31 installed on the tracheal tube 1. A Y-shaped through-hole 32 is opened inside one side of the first balloon 31. The bronchial occlusion tube 2 is slidably inserted inside the Y-shaped through-hole 32.

[0021] Referring to Figure 3 and Figure 4 , a plurality of elastic silica gel flaps 33 are connected to the first balloon 31. A cavity 34 is opened inside the elastic silica gel flap 33. An inner valve 35 is connected to one side of the elastic silica gel flap 33.

[0022] It should be noted that when the tracheal tube 1 and the bronchial occlusion tube 2 are used, a guiding tube is required. The guiding tube has a certain curvature and elasticity and fits the curvature of the laryngoscope. The first balloon 31 and the tracheal tube 1 are integrally injection-molded. The Y-shaped through-hole 32 is opened inside the first balloon 31. The elastic silicone flap 33 is circular in the normally closed state and is adapted to the shape at the through-hole of the Y-shaped through-hole 32. The inner valve 35 and the elastic silicone flap 33 are integrally injection-molded. By opening a cavity 34 inside the elastic silicone flap 33, when the elastic silicone flap 33 is deformed by an external force, the air pressure inside the cavity 34 can cooperate with the elasticity of the elastic silicone flap 33 itself, so that the elastic silicone flap 33 and the inner valve 35 can fit the outer wall of the bronchial occlusion tube 2.

[0023] Reference Figure 2 and Figure 3 As shown, a first air port 4 and a second air port 5 are respectively arranged on the tracheal tube 1. A second balloon 6 is arranged on the tracheal tube 1. The air outlet end of the first air port 4 is communicated with the inside of the first balloon 31, and the air outlet end of the second air port 5 is communicated with the inside of the second balloon 6.

[0024] Reference Figure 1 and Figure 2 As shown, a wire hole 7 is arranged at one end of the tracheal tube 1, and a third balloon 8 is arranged on the bronchial occlusion tube 2.

[0025] It should be noted that the first air port 4 is communicated with the inside of the first balloon 31 through a trachea, the second air port 5 is communicated with the inside of the second balloon 6 through a trachea. The tracheas of the first air port 4 and the second air port 5 are embedded inside the tracheal tube 1. The third balloon 8 is connected to the air port on the bronchial occlusion tube 2. Anti-backflow measures are taken for the other air ports of the first air port 4 and the second air port 5 to avoid the situation that the gas inside the first balloon 31, the second balloon 6 and the third balloon 8 leaks out through the air ports.

[0026] The working principle of a tracheal catheter device with an external bronchial occluder provided by the present invention is as follows:

[0027] During use, the bronchial occlusion tube 2 and the tracheal tube 1 are sleeved on the guiding tube, and then the bronchial occlusion tube 2 is inserted into the interior of the Y-shaped through hole 32 of the first balloon 31 through the guiding tube. When the multiple elastic silica gel flap blocks 33 at the through hole of the Y-shaped through hole 32 on the first balloon 31 are squeezed by the bronchial occlusion tube 2, the elastic silica gel flap blocks 33 are deformed, enabling the bronchial occlusion tube 2 to enter the interior of the Y-shaped through hole 32 and extend out from the bottom of the Y-shaped through hole 32. After the installation is completed, the root of the patient's tongue is lifted by a laryngoscope, the guiding tube is inserted into the human trachea, and then the tracheal tube 1 is fed into the trachea along the guiding tube. The interior of the first balloon 31 is inflated through the first air port 4, causing the first balloon 31 to expand and block the trachea inside the human body. When the first balloon 31 is deformed, the inner wall of the first balloon 31 can fit against the outer wall of the bronchial occlusion tube 2 to ensure the sealing performance of the occlusion of the first balloon 31. Since the opening of the Y-shaped through hole 32 is Y-shaped, during the deformation process of the first balloon 31, the elastic silica gel flap blocks 33 on the Y-shaped through hole 32 will be squeezed inward by the external force, enabling the elastic silica gel flap blocks 33 to fit against the outer wall of the bronchial occlusion tube 2. The interior of the second balloon 6 is inflated through the second air port 5, and the second balloon 6 can cooperate with the first balloon 31 to ensure the occlusion effect of the human trachea. The air port on the bronchial occlusion tube 2 inflates the interior of the third balloon 8, thereby enabling the third balloon 8 to occlude the bronchus. After the operation, the first balloon 31 can be loosened, and the bronchial occlusion tube 2 can be withdrawn through the Y-shaped through hole 32. The elastic silica gel flap blocks 33 and the inner valve 35 are restored to block the Y-shaped through hole 32, preventing the sudden ventilation of both lungs after a long operation and causing damage to the lungs. Then, the second balloon 6 is slowly deflated to allow both lungs to ventilate. The removal of the tracheal tube 1 can be carried out by the ICU medical staff according to the actual situation.

Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present invention.
