Description

Technical Field

[0001] The present invention relates to the technical field of closed drains, in particular to a clinical closed drain for thoracic surgery that is prevented from accidental touch. Background Art

[0002] Closed thoracic drainage involves placing one end of a drainage tube into the chest cavity and connecting the other end to a water-seal bottle located lower than the tube. This allows for the removal of air or collection of fluid within the chest cavity, allowing the lungs to reopen and restore function. This procedure is widely used as a treatment for hemothorax, pneumothorax, and empyema, as well as after thoracotomy, and plays a crucial role in the treatment of these conditions.

[0003] In the prior art, 3M tape is usually used to fix the closed chest drainage tube. Since the drainage tube is thick and heavy and the water seal bottle is heavy, the tape limiting the water seal bottle is easily torn by the weight, causing the risk of the closed chest drainage tube being accidentally pulled out. At the same time, the distal end of the drainage tube is connected to the water seal bottle. At this time, the drainage tube is in a fixed position, and it is easy to bend due to the thin tube mouth, affecting the normal drainage. Summary of the Invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: a clinical closed drainage device for thoracic surgery that prevents accidental touch, comprising a water seal bottle and a connecting tube fixedly mounted on the top of the water seal bottle, wherein the end of the connecting tube away from the water seal bottle is fixedly connected to a connecting assembly;

[0005] Drainage tube, the drainage tube is fixedly connected to the water seal bottle through a connecting assembly;

[0006] A fixing component, the fixing component is fixedly connected to the outer side of the drainage tube;

[0007] Among them, the fixing component includes an arc block, which is sleeved on the outside of the drainage tube, and a patch is fixedly connected to the axial outside of the arc block, and the patch is fixedly connected to a connecting block on the side close to the arc block, and a supporting block is fixedly connected to the side of the connecting block away from the patch. The connecting block is fixedly connected to a limiting block near the inner wall of the drainage tube, and the top of the supporting block is slidably connected to a square plate. When working, the medical staff first trims the peripheral shape of the patch according to the situation around the drainage tube, and then disinfects the skin around the drainage tube with medical disinfectant alcohol. The drainage tube directly passes through the middle of the arc block, and the patch is torn off after adjusting the position. The protective film of the patch sticks tightly to the skin to fix the drainage tube, ensuring that the drainage tube is not easily displaced or falls off, especially when the patient moves or turns over, and the drainage tube is turned and clamped inside the circular hole. By setting a slot and a block, the square plate and the cover plate are clamped on the support block, and then the drainage tube installed on the support block is pressed and fixed in position. The top of the limit block is fixedly connected to a compression spring, and the middle block is fixedly connected to the middle of the square plate near one end of the support block. The two ends of the compression spring are respectively fixedly connected to the middle block and the limit block. A cover plate is provided on the top of the square plate, and the square plate is hinged to the cover plate.

[0008] Preferably, a circular hole is provided in the middle of the interior of the support block, and there are multiple limit blocks, which are evenly distributed around the drainage tube. By arranging the limit blocks circumferentially on the drainage tube, the limit blocks fit tightly with the outer wall of the drainage tube, which can limit the movement of the drainage tube in all directions, preventing it from sliding unnecessary inside or outside the body, thereby preventing the drainage tube from falling out of the body or shifting inside the body, ensuring that the drainage tube is always in the correct drainage position, and maintaining an effective drainage function. The compression spring is located inside the circular hole, and an inner cavity is provided inside the support block. The square plate is fixedly connected to a slider near the outer side of the support block, and the slider is located inside the inner cavity. The support block and the square plate are slidably connected through the slider and the inner cavity. A slot is provided on the inner side of the slider near the limit block, and there are multiple slots, which are evenly distributed on the slider. The inner wall of the inner cavity near the slot is fixedly connected to a block, and the block is elastic, and one end of the block is connected to the inside of the inner cavity. When the medical staff presses the square plate, the square plate drives the slider to slide downward inside the inner cavity, so that the slider and the inner cavity are The internal clamping block contacts and generates extrusion, and the clamping block is compressed by force, so that the slider passes smoothly. Then, under the elastic force of the clamping block, the clamping block is reset. At this time, the clamping block is located inside the clamping groove, so that the square plate and the supporting block are clamped together through the clamping groove and the clamping block. Combined with the wrapping of the drainage tube by the circular hole, the axial and radial movement of the pipeline can be effectively restricted. At the same time, by setting a compression spring and utilizing the elastic force of the compression spring, the clamping structure can apply appropriate clamping force to the drainage tube to ensure that the drainage tube is firmly fixed and prevent it from shifting or falling out. When the patient moves, the drainage tube will be subjected to a certain amount of tension and displacement. The elasticity of the compression spring and the card block can buffer these external forces, prevent the drainage tube from being over-pulled, and reduce the risk of accidental extubation. Therefore, there are multiple card blocks, and the multiple card blocks are evenly distributed inside the inner cavity. The card blocks and the card slots are snap-fitted together. A through hole is provided inside the square plate, and a through hole is provided on the side of the cover plate close to the square plate. The two through holes form a circular hole. The drainage tube is located inside the circular hole, and a circular groove is provided on the support block close to the top edge of the square plate.

[0009] Preferably, the connecting assembly includes a connecting tube, and there are two connecting tubes, the inner wall of one connecting tube is fixedly connected to the outer side of the drainage tube, the connecting tube is sleeved on the outer side of one end of the drainage tube, and the inner wall of the other connecting tube is fixedly connected to the outer side of the connecting tube, and the opposite side of the connecting tube is rotatably connected with an adjusting piece, and the adjusting piece is located at the interval between the two connecting tubes, the inner wall of the connecting tube is fixedly connected to an intermediate tube, and the intermediate tube is fixedly connected to an extension tube axially outward away from one end of the connecting tube, and the connecting tube and the intermediate tube are respectively located on the outer side and the inner side of the drainage tube. At this time, the connecting tube and the intermediate tube constitute a double-layer sleeve design, which enhances the stability of the connection. At the same time, the connecting tube, as an independent force-bearing component, can disperse the tension and bending force at the pipeline connection to avoid the drainage tube or the connecting tube. The interface is directly subjected to external force, resulting in rupture or deformation. A circular plate is fixedly connected to the inner wall of the extension tube near one end of the adjusting part. A through groove is provided inside the circular plate. There are two through grooves, and the two through grooves are evenly distributed on the circular plate. A trapezoidal hole is provided on the inner wall of the middle tube away from the end of the circular plate. A convex ring is fixedly connected to the outer side of the extension tube. The convex ring is located inside the annular groove, so that the convex ring and the annular groove form a labyrinth-shaped sealing structure to prevent the drainage fluid from leaking out of the body, avoid contaminating the wound, bed sheets or operating environment, reduce the cleaning burden of medical staff and the risk of infection for patients, and prevent external air or bacteria from flowing back into the body through the connection to prevent secondary infection, pneumothorax or other complications. There are multiple convex rings, and multiple convex rings are evenly arranged on the extension tube.

[0010] The cam is secured to the outside of the two guide rails and is located adjacent to the two rails, with the guide rails being secured to the outside of the two guide rails and having two intermediate plates. The inner wall of the slide groove is provided with a return spring, and two ends of the return spring are fixedly connected with the inner wall of the slide groove and one end of the cylinder.

[0011] Preferably, the water seal bottle includes a bottle body, and a partition is fixedly connected to the inside of the bottle body. There are multiple partitions. By setting the partitions, when the liquid passes through the dislocated partitions, the flow path will become longer, which plays a certain buffering role and slows down the flow rate of the liquid. During the drainage process, if the drainage liquid flow rate is large, the partition can prevent the liquid from quickly impacting the water seal part or causing a sharp change in the pressure in the bottle. At the same time, it can also limit the backflow of the liquid to a certain extent. When the position of the bottle body changes, the possibility of the drainage liquid flowing back to the body cavity along the connecting tube and the drainage tube is reduced. The multiple partitions are alternately arranged left and right in the vertical direction. A feed pipe is fixedly connected to the top of the bottle body, and sterile water or saline is injected into the bottle body to form a liquid column of a certain height. When the internal pressure is greater than the bottle body pressure, the accumulated fluid and gas in the chest cavity enter the interior of the bottle body through the drainage tube, connecting tube and feed pipe. The gas overflows in the form of bubbles, and the liquid remains in the bottle body. A physical barrier is formed by the pressure of the liquid column, which prevents outside air from entering while allowing gas to be discharged in one direction. The feed pipe runs through the bottle body, and the outer side of the top of the feed pipe is fixedly connected to the connecting pipe. The top of the bottle body away from the feed pipe is fixedly connected to an exhaust piece, and the inside of the feed pipe is fixedly connected to a limit piece.

[0012] Preferably, the limiter includes a cross plate, which is fixedly connected to the inner wall of the feed tube, and the cross plate is arranged perpendicular to the feed tube. The middle part of the cross plate is fixedly connected to a fixed rod. When the pressure in the body is greater than the pressure in the drainage bottle, the accumulated fluid and gas in the chest cavity enter the interior of the feed tube along the drainage tube and the connecting tube under the action of the pressure difference. At this time, the baffle is deformed by force, so that the liquid and gas enter the interior of the bottle body through the gap between the baffle and the feed tube, and the liquid and gas are allowed to pass through. When the pressure in the drainage bottle increases or the pressure in the body decreases, the liquid in the bottle body contacts the baffle, and the baffle does not deform under the support of the cross plate. At this time, the pipeline leading to the connecting tube is closed to prevent the drainage liquid and gas from flowing back. The fixed rod passes through the cross plate, and the outer side of the fixed rod is fixedly connected to the baffle. The end of the fixed rod close to the baffle is fixedly connected to the arc plate.

[0013] Preferably, the exhaust component includes an exhaust pipe, which is fixedly connected to the bottle body, and a cylinder is fixedly connected to the top of the exhaust pipe. The cylinder is connected to the exhaust pipe, and a filter cartridge is fixedly connected at the middle of the interior of the cylinder. The filter cartridge is made of hydrophobic filter material, and the inner wall of the cylinder is fixedly connected to a fixed plate. The fixed plate plays a role of a fixed support, and the gas inside the bottle enters the interior of the cylinder through the exhaust pipe and the limit cylinder. The gas entering the cylinder is evenly in contact with the filter cartridge under the diversion action of the fixed plate, and then passes through the filter cartridge and is discharged from the top. The exhausted gas may carry pathogens in the patient's body. The filter cartridge can prevent pathogens from entering the ward or the air, protecting medical staff and other patients. At the same time, since the filter cartridge has a porous and uniform structure, the exhausted airflow can be dispersed to avoid turbulence or pressure fluctuations caused by concentrated gas injection. One side of the fixed plate is fixedly connected to the outer side of the filter cartridge, and there are multiple fixed plates. The inner wall of the exhaust pipe near one end of the cylinder is fixedly connected to the limit cylinder, and the inner wall of the exhaust pipe is fixedly connected to an inclined plate. There are two inclined plates, and the two inclined plates are symmetrically arranged inside the exhaust pipe.

[0014] The present invention provides a closed drainage device for thoracic surgery that prevents accidental touch. It has the following beneficial effects:

[0015] 1. The anti-accidental-touch clinical closed drainage device for thoracic surgery allows the drainage tube to pass directly through the middle of the arc block. After adjusting the position, the protective film of the patch is torn off and adhered to the skin to complete the fixation of the drainage tube, ensuring that the drainage tube is not easy to shift or fall off, especially when the patient moves or turns over. The drainage tube is turned and clamped inside the circular hole. By setting a clamping slot and a clamping block, the square plate and the cover plate are clamped on the supporting block, and then the drainage tube installed on the supporting block is pressed and fixed in position.

[0016] 2. The anti-accidental-touch clinical closed drain for thoracic surgery has limit blocks set around the drainage tube. The limit blocks fit tightly with the outer wall of the drainage tube, which can limit the movement of the drainage tube in all directions and prevent it from sliding unnecessary inside or outside the body, thereby avoiding the drainage tube from falling out of the body or shifting inside the body, ensuring that the drainage tube is always in the correct drainage position and maintaining an effective drainage function.

[0017] 3. The anti-accidental-touch clinical closed drain for thoracic surgery is equipped with a compression spring. The elastic force of the compression spring is used to enable the clamping structure to apply appropriate clamping force to the drainage tube, ensuring that the drainage tube is firmly fixed and preventing it from shifting or falling out. When the patient moves, the drainage tube will be subjected to a certain amount of tension and displacement. The elasticity of the compression spring and the clamping block can buffer these external forces, avoid excessive pulling of the drainage tube, and reduce the risk of accidental extubation.

[0018] 4. The anti-accidental-touch clinical closed drainage device for thoracic surgery has a connecting tube and an intermediate tube located on the outside and inside of the drainage tube respectively. At this time, the connecting tube and the intermediate tube form a double-layer sleeve design to enhance the stability of the connection. At the same time, the connecting tube serves as an independent force-bearing component, which can disperse the tension and bending force at the pipeline connection, avoiding the drainage tube or the connecting tube interface from being directly subjected to external force and causing rupture or deformation.

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] The first embodiment, as Figures 1 to 4 As shown, the present invention provides a technical solution: a clinical closed drainage device for thoracic surgery that prevents accidental touch, comprising a water seal bottle 1, and a connecting tube 2 fixedly mounted on the top of the water seal bottle 1, wherein the end of the connecting tube 2 away from the water seal bottle 1 is fixedly connected to a connecting component 3;

[0031] Drainage tube 5, which is fixedly connected to the water seal bottle 1 through the connecting assembly 3;

[0032] A fixing component 4, which is fixedly connected to the outer side of the drainage tube 5;

[0033] Among them, the fixing component 4 includes an arc block 42, which is sleeved on the outside of the drainage tube 5, and the axial outside of the arc block 42 is fixedly connected to the patch 41, and the patch 41 is fixedly connected to the side of the arc block 42 close to the arc block 42. The side of the connecting block 43 away from the patch 41 is fixedly connected to the supporting block 44, and the connecting block 43 is fixedly connected to the limiting block 412 near the inner wall of the drainage tube 5. The top of the supporting block 44 is slidably connected to the square plate 47. When working, the medical staff first trims the peripheral shape of the patch 41 according to the situation around the drainage tube, and then disinfects the skin around the drainage tube with medical disinfectant alcohol. The drainage tube directly passes through the middle of the arc block 42, and the patch 41 is torn off after adjusting the position. The protective film sticks tightly to the skin to complete the fixation of the drainage tube, ensuring that the drainage tube is not easily displaced or falls off, especially when the patient moves or turns over, the drainage tube 5 is turned and clamped inside the circular hole. By setting the clamping groove 410 and the clamping block 411, the square plate 47 and the cover plate 48 are clamped on the support block 44, and then the drainage tube mounted on the support block 44 is pressed and fixed in position. The top of the limit block 412 is fixedly connected to the compression spring 49, and the middle of the square plate 47 near one end of the support block 44 is fixedly connected to the middle block 413, and the two ends of the compression spring 49 are respectively fixedly connected to the middle block 413 and the limit block 412. A cover plate 48 is provided on the top of the square plate 47, and the square plate 47 is hinged to the cover plate 48.

[0034] A circular hole 415 is provided in the middle of the inner part of the support block 44, and there are multiple limit blocks 412. The multiple limit blocks 412 are evenly distributed with the drainage tube 5 as the center. By arranging the limit blocks 412 circumferentially on the drainage tube 5, the limit blocks 412 are tightly matched with the outer wall of the drainage tube 5, which can limit the movement of the drainage tube 5 in all directions, preventing it from sliding unnecessarily inside or outside the body, thereby avoiding the drainage tube 5 from falling out of the body or shifting inside the body, ensuring that the drainage tube 5 is always in the correct drainage position, and maintaining an effective drainage function. The compression spring 49 is located inside the circular hole 415, and the inner part of the support block 44 is provided with an inner cavity 45. The square plate 4 7 A slider 46 is fixedly connected to the outside of the support block 44. The slider 46 is located inside the inner cavity 45. The support block 44 and the square plate 47 are slidably connected to the inner cavity 45 through the slider 46. A card slot 410 is opened on the inner side of the slider 46 near the limit block 412. There are multiple card slots 410, and the multiple card slots 410 are evenly distributed on the slider 46. A card block 411 is fixedly connected to the inner side wall of the inner cavity 45 near the card slot 410. The card block 411 is elastic, and one end of the card block 411 is connected to the inside of the inner cavity 45. The medical staff presses the square plate 47, and the square plate 47 drives the slider 46 to slide downward inside the inner cavity 45, so that the slider 4 6 contacts and squeezes the block 411 inside the inner cavity 45. The block 411 is compressed by force, allowing the slider 46 to pass smoothly. Then, under the elastic force of the block 411, the block 411 is reset. At this time, the block 411 is located inside the card groove 410, so that the square plate 47 and the supporting block 44 are engaged with each other through the card groove 410 and the block 411. Combined with the wrapping of the drainage tube by the circular hole, the axial and radial movement of the pipeline can be effectively restricted. At the same time, by providing a compression spring 49, the elastic force of the compression spring 49 can be used to make the card connection structure apply appropriate clamping force to the drainage tube, ensuring that the drainage tube is firmly fixed and prevented from shifting or falling out. When the patient moves, the drainage tube 5 will be subjected to a certain amount of tension and displacement. The elasticity of the compression spring 49 and the block 411 can buffer these external forces, prevent the drainage tube 5 from being over-pulled, and reduce the risk of accidental tube removal. There are multiple blocks 411, and the multiple blocks 411 are evenly distributed inside the inner cavity 45. The blocks 411 are snap-fitted with the slots 410. A through hole 414 is provided inside the square plate 47, and a through hole 414 is provided on the side of the cover plate 48 close to the square plate 47. The two through holes 414 form a circular hole, and the drainage tube 5 is located inside the circular hole. A circular groove 416 is provided on the support block 44 close to the top edge of the square plate 47.

The connecting tube 31 and the intermediate tube 32 are respectively located on the outer side and the inner side of the drainage tube 5. At this time, the connecting tube 31 and the intermediate tube 32 constitute a double-layer sleeve design to enhance the stability of the connection. At the same time, the connecting tube, as an independent force-bearing component, can disperse the tension and bending force at the pipeline connection to avoid the drainage tube 5 or the connecting tube 2. The interface is directly subjected to external force, causing rupture or deformation. The inner wall of the extension tube 38 near the end of the adjusting member 36 is fixedly connected to the circular plate 34, and a through groove 35 is opened inside the circular plate 34. There are two through grooves 35, and the two through grooves 35 are evenly distributed on the circular plate 34. The inner wall of the intermediate tube 32 away from the end of the circular plate 34 is provided with a trapezoidal hole 33. The outer side of the extension tube 38 is fixedly connected to a convex ring 37, and the convex ring 37 is located inside the annular groove 366, so that the convex ring 37 and the annular groove 366 form a labyrinth-shaped sealing structure to prevent the drainage fluid from leaking out of the body, avoid contaminating the wound, bed sheets or operating environment, reduce the cleaning burden of medical staff and the risk of infection for patients, and also prevent external air or bacteria from flowing back into the body through the connection to prevent secondary infection, pneumothorax or other complications. There are multiple convex rings 37, and multiple convex rings 37 are evenly arranged on the extension tube 38.

[0036] The adjusting member 36 includes a swivel 361, the outer side of the swivel 361 is rotatably connected to the two connecting tubes 31 on both sides, the swivel 361 is located at the interval between the two connecting tubes 31, the inner wall of the swivel 361 is fixedly connected with a round rod 362, the round rod 362 is located inside the swivel 361, and the end of the round rod 362 away from the swivel 361 is fixedly connected with an intermediate plate 363. There are multiple round rods 362, and the multiple round rods 362 are evenly distributed with the intermediate plate 363 as the center. The axial outer side of the intermediate plate 363 is fixedly connected with a limiting ring 365, and there are two limiting rings 365. The two limiting rings 365 are symmetrically arranged on both sides of the intermediate plate 363. When in use, the staff rotates The rotating ring 361 drives the middle plate 363 and the limiting ring 365 to rotate through the round rod 362, so that the overlapping area between the notch 364 on the middle plate 363 and the through groove 35 on the circular plate 34 increases until the notch 364 and the through groove 35 overlap. By adjusting the rotation of the rotating ring 361, the cross-sectional area of the connection can be changed, thereby achieving the effect of accurately controlling the flow rate, thereby avoiding the negative pressure imbalance or tissue damage caused by too fast drainage, or the treatment effect affected by too slow drainage. The middle plate 363 is provided with a notch 364 inside, and the number of the notches 364 is two, and the two notches 364 are evenly distributed on the middle plate 363. The notches 364 are located at the limiting ring 365. The inner wall of the limit ring 365 is provided with an annular groove 366, the limit ring 365 is sleeved on the outer side of the extension tube 38, the convex ring 37 is located inside the annular groove 366, and the inner wall of the swivel 361 is provided with a sliding groove 367. There are multiple sliding grooves 367, and the multiple sliding grooves 367 are respectively provided on both sides of the swivel 361. The multiple sliding grooves 367 on one side of the swivel 361 are evenly distributed on the swivel 361. The inner wall of the sliding groove 367 is slidably connected with a cylinder 369. A limiting hole is provided on the side of the connecting tube 31 close to the cylinder 369. There are multiple limiting holes, and the multiple limiting holes are evenly distributed on the connecting tube 31. In the initial state, the cylinder 369 is located at the limiting position. Inside the hole, when the swivel 361 rotates, extrusion is generated between the cylinder 369 inside the swivel 361 and the connecting tube 31, and the return spring 368 is compressed. The return spring 368 drives the cylinder 369 to move toward the inside of the slide groove 367, so that the swivel 361 rotates smoothly. When the swivel 361 stops rotating, the cylinder 369 is reset under the elastic force of the return spring 368, so that the cylinder 369 is located inside the limiting hole, which plays a self-locking role to prevent accidental touch and cause unnecessary harm. The inner wall of the slide groove 367 is provided with a return spring 368, and the two ends of the return spring 368 are fixedly connected to the inner wall of the slide groove 367 and one end of the cylinder 369 respectively.

[0037] The third embodiment, based on the first and second embodiments, see Figures 7 to 9As shown, the water seal bottle 1 includes a bottle body 11, and a partition 12 is fixedly connected to the interior of the bottle body 11. There are multiple partitions 12. By setting the partitions 12, when the liquid passes through the dislocated partitions 12, the flow path will become longer, which plays a certain buffering role and slows down the flow rate of the liquid. During the drainage process, if the drainage liquid flow rate is large, the partition can prevent the liquid from quickly impacting the water seal part or causing a sharp change in the pressure in the bottle. At the same time, it can also limit the backflow of the liquid to a certain extent. When the position of the bottle body 11 changes, the possibility of the drainage liquid flowing back to the body cavity along the connecting tube 2 and the drainage tube 5 is reduced. The multiple partitions 12 are alternately arranged left and right in the vertical direction, and the top of the bottle body 11 is A feeding pipe 13 is fixedly connected to the bottle body 11, and sterile water or physiological saline is injected into the bottle body 11 to form a liquid column of a certain height. When the internal pressure is greater than the bottle body pressure, the accumulated fluid and gas in the chest cavity enter the interior of the bottle body 11 through the drainage tube 5, the connecting tube 2 and the feeding pipe 13. The gas overflows in the form of bubbles, and the liquid remains in the bottle body 11. A physical barrier is formed by the pressure of the liquid column, which prevents the outside air from entering while allowing the gas to be discharged in one direction. The feeding pipe 13 runs through the bottle body 11, and the outer side of the top of the feeding pipe 13 is fixedly connected to the connecting pipe 2. The top of the bottle body 11 away from the feeding pipe 13 is fixedly connected with an exhaust part 14, and the inside of the feeding pipe 13 is fixedly connected to a limiting part 15.

[0038] The limiting member 15 includes a cross plate 152, which is fixedly connected to the inner wall of the feeding tube 13. The cross plate 152 is arranged perpendicular to the feeding tube 13. The middle part of the cross plate 152 is fixedly connected to a fixing rod 151. When the pressure in the body is greater than the pressure of the drainage bottle, the effusion and gas in the chest cavity enter the interior of the feeding tube 13 along the drainage tube 5 and the connecting tube 2 under the action of the pressure difference. At this time, the baffle 153 is deformed by the force, so that the liquid and gas enter through the gap between the baffle 153 and the feeding tube 13. The interior of the bottle body 11 allows liquid and gas to pass through at this time. When the pressure in the drainage bottle increases or the pressure in the body decreases, the liquid in the bottle body 11 contacts the baffle 153. The baffle 153 does not deform under the support of the cross plate 152. At this time, the pipeline leading to the connecting pipe 2 is closed to prevent the drainage liquid and gas from flowing back. The fixing rod 151 passes through the cross plate 152. The outer side of the fixing rod 151 is fixedly connected to the baffle 153, and the end of the fixing rod 151 close to the baffle 153 is fixedly connected to the arc plate 154.

[0039] The exhaust member 14 includes an exhaust pipe 141, which is fixedly connected to the bottle body 11. The top of the exhaust pipe 141 is fixedly connected to a cylinder 144, which is communicated with the exhaust pipe 141. A filter cartridge 146 is fixedly connected to the middle of the cylinder 144. The filter cartridge 146 is made of a hydrophobic filter material. The inner wall of the cylinder 144 is fixedly connected to a fixing plate 145, which plays a role of a fixed support. The gas inside the bottle 11 enters the interior of the cylinder 144 through the exhaust pipe 141 and the limiting cylinder 143. The gas entering the cylinder 144 is evenly contacted with the filter cartridge 146 under the diversion effect of the fixing plate 145, and then passes through the filter cartridge 146 from The gas discharged from the top may carry pathogens in the patient's body. The filter cartridge 146 can prevent pathogens from entering the ward or the air, protecting medical staff and other patients. At the same time, since the filter cartridge 146 has a porous and uniform structure, the discharged airflow can be dispersed to avoid turbulence or pressure fluctuations caused by concentrated gas injection. One side of the fixed plate 145 is fixedly connected to the outer side of the filter cartridge 146. There are multiple fixed plates 145. The inner wall of the exhaust pipe 141 near one end of the cylinder body 144 is fixedly connected to the limiting cylinder 143. The inner wall of the exhaust pipe 141 is fixedly connected to the inclined plate 142. There are two inclined plates 142, and the two inclined plates 142 are symmetrically arranged inside the exhaust pipe 141.

[0040] When in use, medical staff first trim the shape of the patch 41 around the drainage tube according to the situation around the drainage tube, and then use medical disinfectant alcohol to disinfect the skin around the drainage tube. The drainage tube is directly inserted through the middle of the arc block 42. After adjusting the position, the protective film of the patch 41 is torn off and the skin is adhered tightly to complete the fixation of the drainage tube.

[0041] The medical staff presses the square plate 47, so that the square plate 47 drives the slider 46 to slide downward inside the inner cavity 45, so that the slider 46 contacts and squeezes the block 411 inside the inner cavity 45, and the block 411 is compressed, so that the slider 46 passes smoothly. Then, under the elastic force of the block 411, the block 411 is reset. At this time, the block 411 is located inside the slot 410, so that the square plate 47 and the support block 44 are engaged through the slot 410 and the block 411. Combined with the wrapping of the drainage tube by the circular hole, the axial and radial movement of the pipeline can be effectively limited.

[0042] Sterile water or physiological saline is injected into the bottle body 11 to form a liquid column of a certain height. When the body pressure is greater than the bottle pressure, the accumulated fluid and gas in the chest cavity enter the interior of the bottle body 11 through the drainage tube 5, the connecting tube 2 and the feeding tube 13.

[0043] The gas inside the bottle body 11 enters the interior of the cylinder 144 through the exhaust pipe 141 and the limiting cylinder 143. The gas entering the cylinder 144 is evenly contacted with the filter cylinder 146 under the diversion effect of the fixing plate 145, and then passes through the filter cylinder 146 and is discharged from the top.
