Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an anti-slip and anti-compression device and method for a bronchial occlusion tube cuff with a grid structure. Background Art

[0002] A bronchial occluder, also known as a bronchial plug, is a medical device used to block a patient's bronchus. It is usually composed of a catheter, a catheter seat, a balloon, a balloon inflation connector, and a possible multi-way airway conversion connector. The balloon is the key part of the occluder, and its size is adjusted by inflation or deflation to achieve bronchial blockage or opening.

[0003] The existing bronchial occluder still has some shortcomings in actual use: 1. The cuff set on the bronchus is easy to shift on the smaller bronchus, which may cause the position of the support tube to shift when supporting the bronchus; 2. After the bronchial occluder is inserted into the patient's bronchus, the mucus produced in the bronchus cannot be cleaned, which easily leads to the accumulation of mucus in the patient's bronchus and is difficult to clean; 3. When inflating the cuff, an external inflation device is required, and it is difficult to control the expansion degree of the cuff, which can easily cause compression to the patient's bronchial wall.

[0015] A method for using a grid structure bronchial occlusion tube cuff anti-slip and anti-compression device, which is applied to the grid structure bronchial occlusion tube cuff anti-slip and anti-compression device as described above, comprises the following steps: S1. First, insert the tube holder into the patient's oral cavity, then pass the outer tube through the tube holder, the mounting tube and the support frame, and after inserting the outer tube into the predetermined bronchus, use the limit clamp to clamp and position the outer tube; S2, clamp the cannula and the docking tube, and then push the push plate horizontally to make the waste liquid collecting tube move horizontally in the suction tube, and at this time, the piston plate can be driven to move, so when the piston plate moves to the side away from the cannula, a negative pressure device will appear in the suction tube, so that the second one-way valve can be in an open state, so that the mucus can be sucked into the suction tube, and when the piston plate approaches the cannula, the mucus entering the suction tube can be squeezed, and after the mucus is subjected to pressure, it can generate pressure on the first one-way valve, so that the first one-way valve is in an open state, so that the mucus can be transported to the waste liquid collecting tube, so when the waste liquid collecting tube moves back and forth horizontally, the mucus in the bronchus can be continuously sucked out, and after the mucus in the bronchus is sucked out, the limiting ring is disconnected from the first threaded ring by rotating the limiting ring, and then the waste liquid collecting tube is taken out, and then the waste liquid collecting tube and the piston plate are disassembled, so that the mucus in the waste liquid collecting tube can be cleaned; S3. After the mucus in the bronchus is completely sucked out, the blocking tube is passed through the outer tube and the inner tube, and one end of the blocking tube is moved to a predetermined position. The adhesive tape is wound around the support shaft, and the bandage is contracted. The outer tube is contracted with the bandage, so that the bent tube contracts and clamps the blocking tube. The adhesive tape is then fixed and bonded, so that the blocking tube can be stably limited. S4. After the threaded cover plate is connected to the fourth threaded ring, the inner lining part of the threaded cover plate will be inserted into the mounting cover, which can push the movable cover to move so that the first vent hole and the second vent hole remain connected. Then, when the air-filling balloon is pressed, the gas in the air-filling balloon can be compressed. At this time, the third one-way valve will be affected by the air pressure and be in an open state. At this time, the gas can enter the mounting cover, and then the gas can be transported to the blocking tube to expand the anti-slip bag cuff. The surface of the anti-slip bag cuff has a grid structure, which can be used to block the bronchus. The fourth one-way valve is in an open state under the action of negative pressure, and the external gas can be sucked into the inflating balloon through the air inlet pipe at this time. Therefore, when the inflating balloon is repeatedly pressed, gas can be supplied to the blocking tube to expand the anti-slip cuff until the anti-slip cuff is expanded to a suitable volume, so that when the patient's bronchus is blocked, the inner wall of the bronchus can be prevented from being crushed; S5. After the anti-slip cuff is expanded to block the bronchus, the threaded cover plate is disconnected from the fourth threaded ring. The tension spring in a stressed state can pull the movable cover to move, causing the first vent hole and the second vent hole to be misaligned, thereby blocking the installation cover and keeping the circumference of the anti-slip cuff unchanged.

[0016] It is to be understood that the foregoing general description and the following detailed description are exemplary only and are not restrictive of the invention.

[0017] Beneficial effects: In the present invention, by providing the inner lining assembly, after the outer tube is inserted into the patient's bronchus, the outer tube and the suction hole on the suction nozzle remain in a connected state, so when the liquid suction assembly is operated, suction can be generated in the outer tube, so that the mucus generated in the patient's bronchus can be sucked out, and at the same time, the inner tube and the mounting ring can play an isolation effect, so that the mucus can only be sucked into the liquid suction assembly, so that the mucus can be collected; In the present invention, the liquid suction assembly can push the collecting member laterally to make the collecting member reciprocate laterally in the suction tube to generate suction, so that the mucus in the bronchus of the patient can be sucked into the outer tube under the cooperation of the first one-way valve and the second one-way valve, and then transported to the suction tube through the docking tube and the cannula, and finally the mucus can be collected by the collecting member; In the present invention, by setting up the air replenishing component, after the balloon component is connected to the fourth threaded ring, the blocking component can be put in a connected state under the push of the blocking component. Thereafter, the air supply tube can be inflated by operating the balloon component, and the gas can be transported into the blocking tube, so that the anti-slip bag cuff can be expanded. The surface of the anti-slip bag cuff has a grid structure, which can stably contact the inner wall of the bronchus when blocking the bronchus, thereby preventing the problem of mesh position deviation.

[0018] When the anti-slip cuff is used to block the patient's bronchus, the present invention can prevent the problem of sliding and has good stability. At the same time, the mucus generated in the bronchus can be sucked out and cleaned in time, and the anti-slip cuff can be expanded to an appropriate circumference without causing a sense of oppression to the patient's bronchus, so it has good convenience in use.

[0025] Example 1: Reference Figure 1-Figure 10 The present embodiment is an anti-slip and anti-compression device, which mainly includes a pipe frame 1, and a mounting pipe 2 is firmly installed at one end of the pipe frame 1. On the pipe frame 1, we fixedly sleeve a bite sleeve 3 to increase the stability of the device. Inside the mounting pipe 2, we further fixedly install a support frame 4, and one side of the support frame 4 is fixedly connected to a limit clamp 6 located outside the mounting pipe 2.

[0026] like Figure 1 and Figure 2 As shown, the pipe sleeve mechanism of the device is composed of an outer pipe 5, which passes through the pipe rack 1, the mounting pipe 2 and the support frame 4 respectively, and fits tightly with the inner wall of the support frame 4. The function of the limit clamp 6 is to clamp the outer pipe 5 to ensure its stability during operation. Inside the outer pipe 5, we installed a lining assembly, and at the same time, on the inner wall of one side of the outer pipe 5, we penetrated and connected a liquid suction assembly.

[0027] like Figure 3As shown, the detailed structure of the lining assembly includes a mounting ring 7 and a hollow frame 8 respectively fixedly mounted in the outer tube 5, and an inner tube 9 is fixedly connected to the side where the mounting ring 7 and the hollow frame 8 are close to each other. A suction nozzle 10 is also fixedly mounted at one end of the outer tube 5, and a plurality of suction holes 11 are provided on the suction nozzle 10 at equal intervals. The blocking tube 28 passes through the inner tube 9 and the suction nozzle 10 respectively, and a sheath 12 is also fixedly mounted on the outer tube 5. Such a design enables the outer tube 5 to maintain a connected state with the suction holes 11 on the suction nozzle 10 after the outer tube 5 is inserted into the patient's bronchus, so that when the liquid suction assembly is operated, suction can be generated in the outer tube 5, and the mucus generated in the patient's bronchus can be effectively sucked out. At the same time, the inner tube 9 and the mounting ring 7 have an isolation effect, ensuring that mucus can only be sucked into the liquid suction assembly, which is convenient for subsequent collection and processing.

[0028] like Figure 4 , Figure 5 and Figure 6 As shown, the structure of the liquid suction component includes a butt joint pipe 13 that passes through the inner wall of one side of the outer tube 5 and is fixedly connected to the inner wall of one side of the outer tube 5, and a cannula 14 is tightly and movably clamped on one end of the butt joint pipe 13. A suction tube 15 is fixedly installed at one end of the cannula 14, and a first threaded ring 16 is fixedly sleeved on the suction tube 15, and a limit ring 17 is threadedly sleeved on the first threaded ring 16. A collecting component is connected through the limit ring 17, and one side of the collecting component extends into the suction tube 15 and fits tightly with the inner wall of the suction tube 15. A second one-way valve 27 is fixedly installed in the cannula 14, and a first one-way valve 26 is connected to the collecting component. By pushing the collecting component laterally so that it performs a laterally reciprocating motion in the suction tube 15 to generate suction, the mucus in the patient's bronchus can be sucked into the outer tube 5 with the cooperation of the first one-way valve 26 and the second one-way valve 27, and then transported to the suction tube 15 through the docking tube 13 and the cannula 14, and finally the mucus is collected by the collecting component.

[0029] like Figure 4 and Figure 5As shown, the specific structure of the collecting member includes a waste liquid collecting barrel 18 that penetrates the limit ring 17, a push plate 19 is fixedly installed on one side of the waste liquid collecting barrel 18, and the other side extends into the suction barrel 15. A connecting ring 20 is fixedly sleeved on the waste liquid collecting barrel 18, a rotating ring 21 is rotatably connected to the connecting ring 20, a second threaded ring 22 is fixedly installed on one side of the rotating ring 21, and a third threaded ring 23 is threadedly connected to the second threaded ring 22. One side of the third threaded ring 23 extends to the outside of the second threaded ring 22 and is fixedly installed with a piston plate 24, and one side of the piston plate 24 is fixedly installed with a sealing ring 25, and the sealing ring 25 is tightly fitted with the inner wall of the suction barrel 15. One side of the waste liquid collecting barrel 18 extends into the third threaded ring 23 and is tightly fitted with the inner wall of the third threaded ring 23, and the first one-way valve 26 penetrates the piston plate 24 and is fixedly connected to the piston plate 24. By pushing the push plate 19 laterally, the waste liquid collection tube 18 is moved laterally in the suction tube 15, thereby driving the piston plate 24 to move. When the piston plate 24 moves to the side away from the cannula 14, the suction tube 15 will be in a negative pressure state, and the second one-way valve 27 will open at this time to suck the mucus into the suction tube 15. When the piston plate 24 approaches the cannula 14, the mucus entering the suction tube 15 will be squeezed, and the mucus will generate pressure on the first one-way valve 26 after being subjected to pressure, so that it opens, thereby transporting the mucus to the waste liquid collection tube 18. After the mucus in the bronchus is sucked out, the limit ring 17 is rotated to disconnect it from the first threaded ring 16, and then the waste liquid collection tube 18 is taken out, and the waste liquid collection tube 18 and the piston plate 24 are disassembled to clean the mucus in the waste liquid collection tube 18.

[0030] like Fig.10 As shown, the blocking mechanism of the device includes a blocking tube 28 that passes through the inner lining component, and a lining tube 31 is installed in the blocking tube 28. A fixing ring 30 located on one side of the blocking tube 28 is fixedly installed on the inner lining tube 31, and an anti-skid bag sleeve 29 is fixedly installed on the fixing ring 30 and one end of the blocking tube 28. A mesh structure is provided on the anti-skid bag sleeve 29 to increase the friction between it and the inner wall of the bronchus to prevent position deviation. A gas replenishing component is connected to the inner wall of one side of the blocking tube 28.

[0031] like Figure 3As shown, a shrinking opening 33 is also provided on the outer tube 5, and a binding band 34 is sleeved. A connecting frame 35 and an adhesive band 37 are fixedly installed on the binding band 34, and a supporting shaft 36 is fixedly installed on the connecting frame 35. The adhesive band 37 is wound around the supporting shaft 36 and connected to the supporting shaft 36. After the blocking tube 28 passes through the outer tube 5 and one end of the blocking tube 28 is moved to a predetermined position, the adhesive band 37 can be wound around the supporting shaft 36, and then the binding band 34 is shrunk, and the outer tube 5 is shrunk by the binding band 34, so that the outer tube 5 is shrunk and clamped on the blocking tube 28. Then, the adhesive band 37 is fixed and bonded, so as to stably limit the blocking tube 28.

[0032] like Figure 8 As shown, the detailed structure of the gas replenishment component includes a gas delivery pipe 32 that penetrates the inner wall of one side of the blocking tube 28 and is fixedly connected to the inner wall of one side of the blocking tube 28, and a mounting cover 38 is fixedly installed at one end of the gas delivery pipe 32. A fourth threaded ring 45 is fixedly sleeved on the mounting cover 38, and a balloon component is connected to the fourth threaded ring 45. The balloon component is used to replenish gas into the blocking tube 28. A blocking component is also installed in the mounting cover 38 to ensure the stable flow of gas and the blocking effect.

[0033] After the balloon component is connected to the fourth threaded ring 45, the blocking component is in a connected state under the push of the blocking component. Then, the balloon component can be operated to inflate the gas delivery tube 32, and the gas can be transported into the blocking tube 28, thereby expanding the anti-slip bag cuff 29. And because the surface of the anti-slip bag cuff 29 has a grid structure, it can stably contact the inner wall of the bronchus when blocking the bronchus, effectively preventing the problem of position deviation.

[0034] like Fig. 9As shown, the specific structure of the balloon component includes a threaded cover plate 46 threadedly connected to the fourth threaded ring 45, and a connecting pipe 47 is fixedly connected to the threaded cover plate 46. A third one-way valve 50 is fixedly installed in the connecting pipe 47, and a balloon 48 is fixedly installed at one end of the connecting pipe 47. An air inlet pipe 49 is fixedly connected to the inner wall of one side of the balloon 48, and a fourth one-way valve 51 is fixedly installed in the air inlet pipe 49. After the threaded cover plate 46 is connected to the fourth threaded ring 45, the lining part of the threaded cover plate 46 will be inserted into the installation cover 38 and push the blocking component to move, so that the blocking component remains in a connected state. After that, when the balloon 48 is pressed, the gas in the balloon 48 can be compressed, and at this time, the third one-way valve 50 will be in an open state due to the air pressure, so that the gas can enter the installation cover 38, and then be transported to the blocking tube 28 to expand the anti-slip bag sleeve 29. When the inflating balloon 48 is restored, a negative pressure state is formed, so the fourth one-way valve 51 is in an open state under the action of the negative pressure, and the external gas can be sucked into the inflating balloon 48 through the air inlet pipe 49. Therefore, when the inflating balloon 48 is repeatedly pressed, gas can be continuously supplied to the blocking tube 28, so that the anti-slip bag cuff 29 is continuously expanded until it expands to a suitable volume. In this way, when the patient's bronchus is blocked, it can avoid pressure injury to the inner wall of the bronchus.

[0035] Example 2: Reference Figure 8 This embodiment is based on the first embodiment, and is a grid structure bronchial blocking tube cuff anti-slip and anti-compression device. The detailed structure of the blocking component includes a limiting tube 39 fixedly installed in the mounting cover 38, and a first vent 40 is provided on the inner walls on both sides of the limiting tube 39. A movable cover 41 is tightly slidably connected in the limiting tube 39, and a second vent 42 is provided on the inner walls on both sides of the movable cover 41. The first vent 40 and the second vent 42 can be movably connected. After the threaded cover plate 46 is connected to the fourth threaded ring 45, the lining part of the threaded cover plate 46 will be inserted into the mounting cover 38 and push the movable cover 41 to move, so that the first vent 40 and the second vent 42 remain in a connected state, so that the gas can be stably transported from the first vent 40 and the second vent 42 to the mounting cover 38.

[0036] like Figure 8As shown, a tension spring 44 is also sleeved on the movable cover 41 and the limit tube 39, and a connecting plate 43 is fixedly installed on one side of the movable cover 41. The two ends of the tension spring 44 are fixedly connected to one side of the limit tube 39 and the connecting plate 43 respectively. After the anti-skid bag sleeve 29 is expanded to block the bronchus, the threaded cover plate 46 can be disconnected from the fourth threaded ring 45. The tension spring 44 in a stressed state will pull the movable cover 41 to move, so that the first vent 40 and the second vent 42 are misaligned, thereby achieving the blocking effect of the installation cover 38. In this way, the circumference of the anti-skid bag sleeve 29 can be kept unchanged, ensuring the stability and durability of the blocking effect, and when it is necessary to release the gas in the anti-skid bag sleeve 29 and the blocking tube 28, only a thin wooden stick is needed to push the movable cover 41 to move, so that the first vent 40 and the second vent 42 are kept connected, and the gas in the anti-skid bag sleeve 29 and the blocking tube 28 can be released.

[0037] The present invention provides a method for using a grid structure bronchial occlusion tube cuff anti-slip and anti-compression device, which is applied to the grid structure bronchial occlusion tube cuff anti-slip and anti-compression device as described above, and comprises the following steps: S1. First, insert the tube holder 1 into the patient's oral cavity, then pass the outer tube 5 through the tube holder 1, the mounting tube 2 and the support frame 4, and after the outer tube 5 is inserted into the predetermined bronchus, use the limit clamp 6 to clamp and position the outer tube 5; S2, the cannula 14 and the butt joint 13 are clamped together, and then the push plate 19 is pushed horizontally to make the waste liquid collection tube 18 move horizontally in the suction tube 15, which can drive the piston plate 24 to move. Therefore, when the piston plate 24 moves to the side away from the cannula 14, a negative pressure device will appear in the suction tube 15, so the second one-way valve 27 can be opened, so that the mucus can be sucked into the suction tube 15. When the piston plate 24 approaches the cannula 14, the mucus entering the suction tube 15 can be squeezed. After that, pressure can be generated on the first one-way valve 26, so that the first one-way valve 26 is in an open state, so that the mucus can be transported to the waste liquid collection tube 18. Therefore, when the waste liquid collection tube 18 moves back and forth horizontally, the mucus in the bronchus can be continuously sucked out. After the mucus in the bronchus is completely sucked out, the limiting ring 17 is rotated to disconnect the limiting ring 17 from the first threaded ring 16, and then the waste liquid collection tube 18 is taken out, and then the waste liquid collection tube 18 and the piston plate 24 are disassembled, so that the mucus in the waste liquid collection tube 18 can be cleaned; S3. After the mucus in the bronchus is completely sucked out, the blocking tube 28 is passed through the outer tube 5 and the inner tube 9, and one end of the blocking tube 28 is moved to a predetermined position. After the adhesive tape 37 is wound around the support shaft 36, the binding tape 34 is contracted, and the outer tube 5 is contracted by the binding tape 34, so that the curved tube 5 contracts and clamps the blocking tube 28, and then the adhesive tape 37 is fixed and bonded, so that the blocking tube 28 can be stably limited. S4. After the threaded cover plate 46 is connected to the fourth threaded ring 45, the inner lining portion of the threaded cover plate 46 will be inserted into the mounting cover 38, which can push the movable cover 41 to move, so that the first vent hole 40 and the second vent hole 42 remain connected. Then, when the inflating balloon 48 is pressed, the gas in the inflating balloon 48 can be compressed. At this time, the third one-way valve 50 will be subjected to the gas pressure and be in an open state. At this time, the gas can enter the mounting cover 38, and then the gas can be transported to the blocking tube 28 to expand the anti-slip bag cuff 29. The surface of the anti-slip bag cuff 29 has a grid structure. When the bronchus is inflated, During the occlusion, the air can stably contact the inner wall of the bronchus, and the problem of the net position deviation can be prevented. When the inflating balloon 48 is restored, the inflating balloon 48 will form a negative pressure state, so the fourth one-way valve 51 will be in an open state under the action of the negative pressure. At this time, the external gas can be sucked into the inflating balloon 48 through the air inlet pipe 49. Therefore, when the inflating balloon 48 is repeatedly pressed, gas can be supplied to the occlusion tube 28 to expand the anti-slip bag cuff 29 until the anti-slip bag cuff 29 is expanded to a suitable volume, so that when the patient's bronchus is blocked, it can avoid the inner wall of the bronchus from being crushed. S5. After the anti-slip bag sleeve 29 is expanded to block the bronchus, the threaded cover plate 46 is disconnected from the fourth threaded ring 45. The tension spring 44 in a stressed state can pull the movable cover 41 to move, so that the first air hole 40 and the second air hole 42 are misaligned, thereby blocking the installation cover 38, thereby keeping the circumference of the anti-slip bag sleeve 29 unchanged.

10. A method for using a mesh structure bronchial occlusion tube cuff anti-slip and anti-compression device, applied to the mesh structure bronchial occlusion tube cuff anti-slip and anti-compression device as claimed in any one of claims 1 to 9, characterized in that: The following steps are involved: S1. First, insert the tube holder (1) into the patient's oral cavity, then pass the outer tube (5) through the tube holder (1), the mounting tube (2) and the support frame (4), and after the outer tube (5) is inserted into the predetermined bronchus, use the limit clamp (6) to clamp and position the outer tube (5); S2. The cannula (14) and the docking tube (13) are clamped together, and the push plate (19) is then pushed laterally to make the waste liquid collection tube (18) move laterally in the suction tube (15). At this time, the piston plate (24) can be driven to move. Therefore, when the piston plate (24) moves to the side away from the cannula (14), a negative pressure device will be present in the suction tube (15). Therefore, the second one-way valve (27) can be in an open state, so that the mucus can be sucked into the suction tube (15). When the piston plate (24) approaches the cannula (14), the mucus entering the suction tube (15) can be squeezed. When the pressure is reached, the first one-way valve (26) can be pressurized, so that the first one-way valve (26) is in an open state, so that the mucus can be transported to the waste liquid collection tube (18), so that when the waste liquid collection tube (18) moves back and forth horizontally, the mucus in the bronchus can be continuously sucked out. After the mucus in the bronchus is completely sucked out, the limit ring (17) is rotated to disconnect the limit ring (17) from the first threaded ring (16), and then the waste liquid collection tube (18) is taken out, and then the waste liquid collection tube (18) and the piston plate (24) are disassembled, so that the mucus in the waste liquid collection tube (18) can be cleaned; S3. After the mucus in the bronchus is completely sucked out, the blocking tube (28) is passed through the outer tube (5) and the inner tube (9), and one end of the blocking tube (28) is moved to a predetermined position. Then, the adhesive tape (37) is wound around the support shaft (36), and the binding tape (34) is retracted. The outer tube (5) is retracted by the binding tape (34), so that the curved tube (5) is retracted and clamped to the blocking tube (28), and then the adhesive tape (37) is fixed and bonded, so that the blocking tube (28) can be stably limited. S4. After the threaded cover plate (46) is connected to the fourth threaded ring (45), the inner lining portion of the threaded cover plate (46) will be inserted into the mounting cover (38), which can push the movable cover (41) to move, so that the first vent hole (40) and the second vent hole (42) remain connected. Then, when the air filling balloon (48) is pressed, the gas in the air filling balloon (48) can be compressed. At this time, the third one-way valve (50) will be subjected to the air pressure and be in an open state. At this time, the gas can enter the mounting cover (38), and then the gas can be transported to the sealing tube (28) to expand the anti-skid bag sleeve (29). The surface of the anti-skid bag sleeve (29) has a grid structure. When the bronchus is blocked, it can stably contact the inner wall of the bronchus, which can prevent the problem of the net position deviation. When the inflating balloon (48) is restored, the inflating balloon (48) will form a negative pressure state, so the fourth one-way valve (51) will be in an open state under the action of the negative pressure. At this time, the external gas can be sucked into the inflating balloon (48) through the air inlet pipe (49). Therefore, when the inflating balloon (48) is repeatedly pressed, gas can be transported into the blocking tube (28) to expand the anti-slip bag cuff (29) until the anti-slip bag cuff (29) is expanded to a suitable volume, so that when the patient's bronchus is blocked, it can avoid causing pressure injuries to the inner wall of the bronchus; S5. After the anti-slip bag sleeve (29) is expanded to block the bronchus, the threaded cover plate (46) is disconnected from the fourth threaded ring (45), and the tension spring (44) in a stressed state can pull the movable cover (41) to move, so that the first ventilation hole (40) and the second ventilation hole (42) are misaligned, thereby blocking the installation cover (38), thereby keeping the circumference of the anti-slip bag sleeve (29) unchanged.
