Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and specifically to a bronchial occluder. Background Art

[0002] Currently, during thoracotomy, in order to effectively perform one-lung ventilation, a bronchial occluder is often required. The currently used bronchial occluder is composed of a blocking balloon, a multi-functional conversion joint connected through a bronchial catheter (occluder suction tube), a Y-shaped joint, and a pre-inflated indicating balloon connected to the Y-shaped joint. When this kind of bronchial occluder is used, especially during right thoracotomy, since the distance from the opening of the left upper lobe of the lung to the carina is about 4 cm, while the distance from the opening of the right upper lobe of the lung to the carina is only about 2 cm. Since the outer shape of the blocking balloon after inflation is an oval spherical structure, during the operation, the blocking balloon is extremely likely to mistakenly block the opening of the right upper lobe of the lung: after mistakenly blocking the opening of the right upper lobe of the lung, in mild cases, the right upper lobe of the lung shows poor atrophy, affecting the exposure of the operative field; in severe cases, lung tissue and important organ tissue damage will occur due to hypoxia.

[0003] There are many hoses on the existing bronchial occluder, which are easily entangled together during use, thus affecting the operation process. In view of the above problems, a bronchial occluder is provided accordingly. Summary of the Invention

[0004] The purpose of the present invention is to provide a bronchial occluder to solve the problems raised in the above background art.

[0005] To solve the above technical problems, the present invention is realized through the following technical solutions: The present invention is a bronchial occluder, including a connector. An auxiliary component is provided on the circumferential side of the connector. The auxiliary component includes a mounting plate, a mounting block, a limiting belt, a connecting block, a positioning belt, a magic tape, and a sticking block. A mounting plate is provided on the circumferential side of the connector. Mounting blocks are provided on the upper surface of the mounting plate. The number of the mounting blocks is fixed at two. Limiting belts are provided on the upper surfaces of the mounting blocks. One end of each limiting belt is provided with a connecting block. A positioning belt is provided on the lower surface of the connecting block. A magic tape is provided on the inner wall of the positioning belt. A sticking block is provided on the outer surface of the positioning belt. By picking up the two limiting belts and then wrapping the branch hoses on the bronchial occluder, after wrapping is completed, sticking the magic tape on the sticking block, the positioning belt can be fixed to the hoses on the bronchial occluder. Since the two limiting belts are arranged in opposite directions, when fixing multiple hoses on the bronchial occluder, the hoses will be separated and pulled, thus avoiding the situation that multiple hoses on the bronchial occluder are entangled together during use, and the practicability is relatively improved.

[0006] Further, two groups of clamping blocks are provided on the outer surface of the connector. Installation grooves are formed on the inner walls of the two groups of clamping blocks. The number of the installation grooves is fixed at two. Springs are arranged on the inner walls of the installation grooves. The number of the springs is fixed at two. One ends of the springs are fixedly installed with pressing blocks. The number of the pressing blocks is fixed at two. The clamping blocks are engaged with the limiting belt, and the pressing blocks are abutted against the limiting belt.

[0007] Further, a fiber bronchoscope access port is provided on the upper surface of the connector.

[0008] Further, a connecting belt is provided on the upper surface of the connector, and a fixing frame is provided at one end of the connecting belt.

[0009] Further, a standard interface for the ventilation circuit is provided on one side of the connector.

[0010] Further, a catheter is provided on the upper surface of the connector. An inflation mechanism is arranged on the outer surface of the catheter, and a speed regulating valve is arranged on the outer surface of the inflation mechanism.

[0011] Further, a protective ring is arranged on the inner wall of the connector. By providing the protective ring, the situation that the trachea is damaged due to friction with the connector is avoided, and the service life of the trachea is increased.

[0012] Further, a trachea is arranged inside the connector, and the trachea is connected to the inflation mechanism through a catheter.

[0013] Further, an airbag is arranged at one end of the trachea, and a suction tube is arranged on the lower surface of the airbag.

[0014] Further, the suction tube includes a suction inlet, a flexible tube body and a tube connector; The tube connector is installed at one end of the airbag, and the tube connector is connected to the tube connector through the flexible tube body; The end of the pull rope passing through the tube connector is fixed on the suction inlet. A hose is arranged inside the trachea, and one end of the hose passes through the tube connector and the flexible tube body in sequence and is fixed inside the suction inlet.

[0015] The present invention has the following beneficial effects: (1) In the present invention, by picking up the two limiting belts and then wrapping the branch hoses on the bronchial occluder, after the wrapping is completed, the magic tape is pasted on the pasting block, and then the positioning belt can be fixed to the hoses on the bronchial occluder. Since the two limiting belts are arranged in opposite directions, when fixing the multiple hoses on the bronchial occluder, the hoses will be separated and pulled, so as to avoid the situation that the multiple hoses on the bronchial occluder are entangled with each other during use, and the practicability is relatively improved.

[0016] (2) The present invention avoids the damage caused by the friction between the trachea and the connector through the setting of the protective ring, increasing the service life of the trachea. Through the cooperation of the spring and the pressing block, when the limiting belt is clamped into the inside of the clamping block, the pressing block can tighten the limiting belt through the resilience of the spring, preventing the limiting belt from easily falling off from the inside of the clamping block.

[0017] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figure 1 - Figure 8 As shown, the present invention is a bronchial occluder, including a connector 1. An auxiliary component 2 is provided on the circumferential side surface of the connector 1. The auxiliary component 2 includes a mounting plate 201, a mounting block 202, a limiting belt 203, a connecting block 204, a positioning belt 205, a magic tape 206, and a sticking block 207. A mounting plate 201 is provided on the circumferential side surface of the connector 1. Mounting blocks 202 are provided on the upper surface of the mounting plate 201. The number of the mounting blocks 202 is fixed at two. Limiting belts 203 are provided on the upper surfaces of the mounting blocks 202. One end of each limiting belt 203 is provided with a connecting block 204. A positioning belt 205 is provided on the lower surface of the connecting block 204. A magic tape 206 is provided on the inner wall of the positioning belt 205. A sticking block 207 is provided on the outer surface of the positioning belt 205. By picking up the two limiting belts 203 and then wrapping the branch hoses on the bronchial occluder, after the wrapping is completed, the magic tape 206 is pasted on the sticking block 207, and the positioning belt 205 can be fixed to the hoses on the bronchial occluder. Since the two limiting belts 203 are arranged in opposite directions, when fixing multiple hoses on the bronchial occluder, the hoses will be separated and pulled, thereby avoiding the entanglement of multiple hoses on the bronchial occluder during use, and the practicability is relatively improved.

[0022] Two groups of clamping blocks 3 are provided on the outer surface of the connector 1. Mounting grooves 301 are opened in the inner walls of the two groups of clamping blocks 3. The number of the mounting grooves 301 is fixed at two. Springs 302 are provided in the inner walls of the mounting grooves 301. The number of the springs 302 is fixed at two. One end of each spring 302 is fixedly installed with a pressing block 303. The number of the pressing blocks 303 is fixed at two. The clamping blocks 3 are engaged with the limiting belts 203, and the pressing blocks 303 are abutted against the limiting belts 203; Through the cooperation of the springs 302 and the pressing blocks 303, when the limiting belts 203 are clamped into the inside of the clamping blocks 3, the pressing blocks 303 can abut against the limiting belts 203 through the resilience of the springs 302, avoiding the easy detachment of the limiting belts 203 from the inside of the clamping blocks 3; A fiber bronchoscope access port 4 is provided on the upper surface of the connector 1.

[0023] A connecting belt 5 is provided on the upper surface of the connector 1. A fixing frame 6 is provided at one end of the connecting belt 5.

[0024] One side of the connector 1 is provided with a standard interface 7 for the ventilation circuit.

[0025] The upper surface of the connector 1 is provided with a conduit 8, the outer surface of the conduit 8 is provided with an inflation mechanism 9, and the outer surface of the inflation mechanism 9 is provided with a speed regulator valve 10.

[0026] The inner wall of the connector 1 is provided with a protective ring 11. By setting the protective ring 11, the trachea 12 is prevented from being damaged due to friction with the connector 1, and the service life of the trachea 12 is increased.

[0027] The inside of the connector 1 is provided with a trachea 12, and the trachea 12 is connected to the inflation mechanism 9 through the conduit 8.

[0028] One end of the trachea 12 is provided with an airbag 13. The airbag 13 is installed at the bent end of the trachea 12. During use, by rotating the trachea 12, the orientation of the end of the airbag 13 is changed, so as to facilitate adjusting the advancing direction of the airbag 13. The lower surface of the airbag 13 is provided with a suction tube 14.

[0029] During use, first pick up the two limit bands 203 and then wrap the branch hoses on the bronchial occluder. After wrapping is completed, paste the magic tape 206 on the paste block 207, and then the positioning band 205 can be fixed to the hose on the bronchial occluder. Since the two limit bands 203 are arranged in opposite directions, when fixing to the multiple hoses on the bronchial occluder, the hoses will be separated and pulled, thus avoiding the situation that the multiple hoses on the bronchial occluder are entangled together during use, and the practicability is relatively improved. By the clamping and fixing of the clamping block 3 to the limit band 203, the limit band 203 will not fall too long and cause inconvenient storage. By setting the protective ring 11, the trachea 12 is prevented from being damaged due to friction with the connector 1, and the service life of the trachea 12 is increased. Through the cooperation of the spring 302 and the pressing block 303, when the limit band 203 is clamped into the inside of the clamping block 3, the pressing block 303 can press and tighten the limit band 203 through the resilience of the spring 302, preventing the limit band 203 from easily falling off from the inside of the clamping block 3.

The nozzle connector 1403 is connected to the nozzle connector 1403 through the flexible tube body 1402. The end of the pull cord 1405 passing through the nozzle connector 1403 is fixed to the suction port 1401. A hose 1404 is arranged inside the trachea 12, and one end of the hose 1404 passes through the nozzle connector 1403 and the flexible tube body 1402 in sequence and is fixed inside the suction port 1401; The flexible tube body 1402 is of a spring structure. At the same time, the cross-sections of the suction inlet 1401, the flexible tube body 1402 and the tube orifice connecting member 1403 are all oval. The pulling rope 1405 is a metal rope. One end of the pulling rope 1405 is welded to the suction inlet 1401. As the length of the pulling rope 1405 extending into the flexible tube body 1402 increases, the flexible tube body 1402 bends to one side; The end of the suction inlet 1401 is a curved surface to avoid scratching the inner wall of the trachea.
