Description

Technical Field

[0001] This invention relates to the field of drainage assistance technology, and more specifically to a drainage assistance device for pleural effusion. Background Technology

[0002] The pleural cavity is a potential space between the visceral and parietal pleura. A normal person's pleural cavity contains 5-15 ml of fluid, which acts as a lubricant during respiration. 500-1000 ml of fluid is formed and absorbed daily within the pleural cavity. Any cause leading to increased fluid production or decreased fluid absorption within the pleural cavity can result in pleural effusion. More severe pleural effusions require drainage. When using drainage tubes, sometimes the tube becomes blocked due to high fluid concentration or the inhalation of tissue debris. This necessitates clearing the tube. Common methods include flushing and repeatedly squeezing the tube. Squeezing the tube changes the fluid pressure within, causing the fluid to surge and thus clearing the blockage. However, this is usually done manually by medical staff or the patient, resulting in low efficiency. A more efficient drainage aid is needed. Summary of the Invention

[0003] To overcome the aforementioned technical problems, the present invention aims to provide an auxiliary device for pleural effusion drainage. Through the arrangement of horizontal and vertical clamps, when the clamping plate passes through the compression unit, it drives the horizontal and vertical clamps to repeatedly compress the drainage tube, causing the fluid inside the tube to surge, thereby clearing the drainage tube. Furthermore, when the clamping plate disengages from the compression unit, the two vertical clamps return to their clamping state on the drainage tube. Thus, as the clamping plate passes through the slide rail from front to back, multiple compression units sequentially clamp the drainage tube after horizontal and vertical compression, squeezing out the original fluid from the rear end of the drainage tube. When the clamping plate is inserted again from the front end of the slide rail and dragged towards the rear end, it again drives multiple compression units to sequentially compress the drainage tube from front to back. After the clamping plate passes through, neither the two horizontal nor two vertical clamps clamp the drainage tube, allowing the drainage tube to return from a compressed, flattened state to a cylindrical state, thereby improving the drainage efficiency of the drainage tube.

[0004] The objective of this invention can be achieved through the following technical solutions: A pleural effusion drainage auxiliary device includes a fixed plate and a clamping plate. Multiple compression units are fixedly connected to the bottom surface of the fixed plate. Each compression unit includes a base plate. Fixed rods are fixedly connected to both sides of one end of the base plate. Two opposing horizontal clamping plates are arranged below the base plate. Connecting rods are fixedly connected to the outer walls of the horizontal clamping plates. One end of the outer wall of the connecting rod is slidably connected to an adjacent fixed rod. A reciprocating module is arranged between the two connecting rods. Vertical clamping plates are arranged between the two ends of the two horizontal clamping plates. A transmission module is arranged between the two vertical clamping plates and the bottom surface of the base plate. A slide rail is fixedly connected to one side of the fixed plate. The clamping plate is slidably connected to the slide rail. When the clamping plate passes the compression units, it drives the horizontal and vertical clamping plates to repeatedly compress the drainage tube, causing the fluid inside the drainage tube to surge, thereby clearing the drainage tube. Furthermore, the clamping plate... When disengaged from the squeezing unit, the two vertical clamps return to their clamping position on the drainage tube. As the clamping plate passes through the slide rail from front to back, multiple squeezing units sequentially clamp the drainage tube after squeezing it horizontally and vertically. This forces the liquid in the drainage tube to be squeezed out from the rear end. When the clamping plate is inserted again from the front end of the slide rail and dragged towards the rear end, it causes the clamping plate to once again drive multiple squeezing units to squeeze the drainage tube sequentially from front to back. After the clamping plate passes through, neither the two horizontal nor the two vertical clamps clamp the drainage tube. This allows the drainage tube to return from its flattened state to a cylindrical state, gradually returning from the front end to the rear end. This allows the accumulated liquid to be drawn in from the front end of the drainage tube. This process of squeezing the drainage tube to clear it while simultaneously squeezing out the liquid from the rear end and drawing it in from the front end improves the drainage efficiency of the drainage tube.

[0005] Furthermore, the transmission module includes a U-shaped frame, the top surface of which is fixedly connected to the bottom surface of the base plate. The U-shaped frame contains multiple sliding columns. Support plates are fixedly connected to both bottom ends of the U-shaped frame. A sliding rod is fixedly connected to the outer wall of the vertical clamping plate, and the sliding rod is slidably inserted into the adjacent support plate. A compression spring is fixedly connected between the vertical clamping plate and the adjacent support plate. A pull rope is fixedly connected to the outer wall of the vertical clamping plate, and one end of the pull rope is fixedly connected to three adjacent sliding columns and a horizontal clamp. The outer walls of the plate are fixed. When the two connecting rods approach each other, they drive the two horizontal clamps to move towards the middle. When one horizontal clamp moves down, it pulls the vertical clamps to both sides through the pull rope, so that the two vertical clamps overcome the elastic force of the compression spring and move away from each other. The vertical clamps and the horizontal clamps move the same distance. The two horizontal clamps squeeze the drainage tube laterally. When the two horizontal clamps move away from each other, the two vertical clamps move towards the middle under the action of the compression spring, so that the two vertical clamps clamp the drainage tube vertically.

[0006] Furthermore, the reciprocating module includes a gear one, a fixed frame one fixedly connected between one side of the two fixed rods, one side of the fixed frame one rotatably connected to the gear one, a fixed frame two fixedly connected between the outer walls of the other side of the two fixed rods, a gear two rotatably connected to the inner wall of one side of the fixed frame two, a toothed groove opened on the outer wall of one end of the connecting rod, the gear one meshing with the two connecting rods, a cylinder one fixedly connected to the outer periphery of one side of the gear one, a cylinder two fixedly connected to the outer periphery of one end of the gear two, a connecting rod rotatably connected between the cylinder one and the cylinder two, and a limiting module for limiting the position of the gear two fixedly connected to the outer wall of the fixed frame two. The forward movement of the clamping plate drives the gear two to rotate, and the gear two drives the gear one to reciprocate through the connecting rod. The reciprocating rotation of the gear one drives the two connecting rods to move towards each other.

[0007] Furthermore, the limiting module includes a fixed base, one end of which is fixedly connected to the outer wall of the second fixing frame, and the other end of which is fixedly connected to a sleeve. A rod is slidably fitted onto the inner wall of the sleeve, one end of which is fixedly connected to a limiting plate. A tension spring is fixedly connected between the sleeve and the limiting plate, and the tension spring is sleeved with the rod. A limiting hole is formed on the outer wall of the other end of the second gear. A guide plate is provided at one end of the clamping plate, and a toothed groove is formed on the bottom surface of the clamping plate. When the clamping plate is inserted from the front end of the slide rail for the second time and dragged towards the rear end, the clamping plate... After the plate passes through gear two, gear two and gear one rotate to state d as shown in the figure. When the plate changes from state d to state a, gear two deflects clockwise under the action of the compression spring, so that the limiting hole is inserted and locked by the insertion rod when it passes through the insertion rod, so that gear two stops at state c. At this time, neither the two horizontal clamps nor the two vertical clamps clamp the drainage tube, so that the drainage tube returns from the compressed flat state to the cylindrical state, and gradually returns from the front end to the rear end, which facilitates the suction of the accumulated liquid from the front end of the drainage tube and improves the drainage efficiency of the drainage tube.

[0008] Furthermore, an insert plate is fixedly connected to the outer wall of the second fixing frame, and one end of the insert plate is slidably inserted into the limiting plate to limit and support the limiting plate and prevent the limiting plate from rotating.

[0009] Furthermore, a gripping plate is fixedly connected to the top surface of the fixing plate, and a gripping plate is fixedly connected to the outer side wall of one side of the clamping plate, which facilitates gripping the fixing plate and the clamping plate.

[0010] Furthermore, the number of tooth grooves on the clamping plate is (n+0.5) times the number of tooth grooves on the outer side of the gear, so that the two vertical clamping plates maintain different states after the clamping plate passes through for the first time and after it passes through for the second time.

[0011] Furthermore, the distance between the centerline of cylinder two and gear two is less than the distance between the centerline of cylinder one and gear one, which facilitates the reciprocating rotation of gear one.

[0012] The beneficial effects of this invention are: 1. With the horizontal and vertical clamping plates, when the clamping plate passes through the extrusion unit, the guide plate presses the limiting plate to the right, causing the limiting plate to overcome the tension of the tension spring and move the insert rod to the right, thus removing it from the limiting hole. This allows the insert rod to release its restriction on gear two, and the clamping plate engages with gear two. The clamping plate moves forward, causing gear two to rotate. Gear two drives gear one to rotate reciprocally via a connecting rod. The reciprocating rotation of gear one drives the two connecting rods to move towards each other. When the two connecting rods approach each other, they cause the two horizontal clamping plates to move towards the center. When one horizontal clamping plate moves downward, it is controlled by a pull rope. Pull the vertical clamps to both sides, causing them to move away from each other against the force of the compression springs. The vertical clamps move the same distance as the horizontal clamps. The two horizontal clamps then compress the drainage tube laterally. When the two horizontal clamps move away from each other, the two vertical clamps move towards the center under the force of the compression springs, thus clamping the drainage tube vertically. When the clamping plate passes the second gear, it drives the second gear to rotate. The second gear drives the horizontal and vertical clamps to repeatedly compress the drainage tube, causing the liquid inside the drainage tube to surge, thereby clearing the drainage tube. 2. Through the setting of the limiting module, the clamping plate passes through the slide rail twice. When the clamping plate passes through the slide rail for the first time, the clamping plate disengages from the squeezing unit, and the two vertical clamping plates return to the state of clamping the drainage tube. Thus, when the clamping plate passes through the slide rail from front to back, multiple squeezing units squeeze the drainage tube horizontally and vertically and then clamp the drainage tube in sequence, thereby squeezing out the liquid originally present in the drainage tube from the rear end of the drainage tube. When the clamping plate passes through for the second time, the horizontal and vertical clamping plates return to the state where neither of the two horizontal or two vertical clamping plates clamps the drainage tube. This allows the drainage tube to return from the squeezed flat state to the cylindrical state, and it gradually returns from the front end to the rear end, thereby sucking the accumulated liquid from the front end of the drainage tube. This achieves the goal of squeezing the drainage tube to clear the drainage tube while squeezing and sucking the accumulated liquid from the rear end and sucking it in from the front end, thereby improving the drainage efficiency of the drainage tube.

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0017] Please see Figure 1-10As shown, a pleural effusion drainage auxiliary device includes a fixing plate 100 and a clamping plate 300. Multiple compression units 200 are fixedly connected to the bottom surface of the fixing plate 100. Each compression unit 200 includes a seat plate 230. Fixing rods 231 are fixedly connected to both sides of one end of the bottom surface of the seat plate 230. Two opposing horizontal clamping plates 210 are arranged below the seat plate 230. A connecting rod 211 is fixedly connected to the outer wall of each horizontal clamping plate 210. One end of the outer wall of the connecting rod 211 is slidably connected to the adjacent fixing rod 231. A reciprocating module 250 is provided between the two connecting rods 211. Vertical clamping plates 220 are provided between both ends of the two horizontal clamping plates 210. A transmission module 240 is provided between the two vertical clamping plates 220 and the bottom surface of the base plate 230. A slide rail 120 is fixedly connected to one side of the fixed plate 100. The clamping plate 300 is slidably connected to the slide rail 120. When the clamping plate 300 passes the extrusion unit 200, it drives the horizontal clamping plates 210 and vertical clamping plates 220 to repeatedly extrude the drainage tube, causing the liquid inside the drainage tube to surge. The drainage tube is cleared, and when the clamping plate 300 disengages from the squeezing unit 200, the two vertical clamping plates 220 return to their clamping state on the drainage tube. This allows multiple squeezing units 200 to sequentially clamp the drainage tube after horizontal and vertical squeezing, thus squeezing out the liquid originally present in the drainage tube from its rear end. When the clamping plate 300 is reinserted from the front end of the slide rail 120 and dragged towards the rear end, the clamping plate 300 is again pulled... Multiple squeezing units 200 squeeze the drainage tube sequentially from front to back. After the clamping plate 300 passes through, the two horizontal clamping plates 210 and the two vertical clamping plates 220 do not clamp the drainage tube, allowing the drainage tube to return from a flattened state to a cylindrical state, and gradually from the front end to the rear end. This allows the accumulated fluid to be drawn in from the front end of the drainage tube. This achieves the goal of squeezing the drainage tube to clear the blockage while simultaneously squeezing out the accumulated fluid from the rear end and drawing it in from the front end, thereby improving the drainage efficiency of the drainage tube.

[0018] The transmission module 240 includes a U-shaped frame 241, the top surface of which is fixedly connected to the bottom surface of the seat plate 230. The interior of the U-shaped frame 241 includes multiple sliding columns 242. Support plates 244 are fixedly connected to both bottom ends of the U-shaped frame 241. A sliding rod 245 is fixedly connected to the outer wall of the vertical clamping plate 220. The sliding rod 245 is slidably inserted into the support plate 244 on the adjacent side. A compression spring 246 is fixedly connected between the vertical clamping plate 220 and the adjacent support plate 244. A pull rope 243 is fixedly connected to the outer wall of the vertical clamping plate 220. One end of the pull rope 243 is fixedly connected to the outer side of a horizontal clamping plate 210 through three adjacent sliding columns 242. The wall is fixed. When the two connecting rods 211 approach each other, they drive the two horizontal clamps 210 to move towards the middle. When one horizontal clamp 210 moves down, it pulls the vertical clamps 220 to both sides through the pull rope 243, so that the two vertical clamps 220 overcome the elastic force of the compression spring 246 and move away from each other. The vertical clamps 220 and the horizontal clamps 210 move the same distance. The two horizontal clamps 210 squeeze the drainage tube laterally. When the two horizontal clamps 210 move away from each other, the two vertical clamps 220 move towards the middle under the action of the compression spring 246, so that the two vertical clamps 220 clamp the drainage tube vertically.

[0019] The reciprocating module 250 includes a gear 252, a fixing bracket 251 fixed between one side of the two fixing rods 231, one side of the fixing bracket 251 rotatably connected to the gear 252, a fixing bracket 256 fixed between the outer walls of the other side of the two fixing rods 231, a gear 255 rotatably connected to the inner wall of one side of the fixing bracket 256, a toothed groove on the outer wall of one end of the connecting rod 211, and the gear 252 meshing with the two connecting rods 211. The outer wall of one side of the gear 252 has a toothed groove. A cylinder 253 is fixedly connected to the position. A cylinder 257 is fixedly connected to the outer periphery of one end of the gear 255. A connecting rod 254 is rotatably connected between the cylinder 253 and the gear 257. A limiting module 260 for limiting the position of the gear 255 is fixedly connected to the outer wall of the fixing frame 256. The forward movement of the clamping plate 300 drives the gear 255 to rotate. The gear 255 drives the gear 252 to reciprocate through the connecting rod 254. The reciprocating rotation of the gear 252 drives the two connecting rods 211 to move towards each other.

[0020] The limiting module 260 includes a fixed base 267. One end of the fixed base 267 is fixedly connected to the outer wall of the second fixed bracket 256. The other end of the fixed base 267 is fixedly connected to a sleeve 261. An insert rod 262 is slidably sleeved on the inner wall of the sleeve 261. One end of the insert rod 262 is fixedly connected to a limiting plate 264. A tension spring 263 is fixedly connected between the sleeve 261 and the limiting plate 264. The tension spring 263 is sleeved with the insert rod 262. A limiting hole 2551 is opened on the outer wall of the other end of the second gear 255. A guide plate 320 is provided on one end of the clamping plate 300. A toothed groove is opened on the bottom surface of the clamping plate 300. When the clamping plate 300 is inserted from the front end of the slide rail 120 for the second time and dragged to the rear end, after the clamping plate 300 passes the second gear 255, the second gear 255 and the first gear 252 rotate to the position shown in the image. Figure 10 As shown in state d, when transitioning from state d to state a, gear 255 rotates clockwise under the action of compression spring 246, causing the limiting hole 2551 to be inserted and engaged by the insertion rod 262 when passing through it. This causes gear 255 to remain in state c, where neither the two horizontal clamping plates 210 nor the two vertical clamping plates 220 clamp the drainage tube. This allows the drainage tube to recover from its compressed, flattened state to a cylindrical state, gradually recovering from the front end to the rear end. This facilitates the suction of accumulated fluid from the front end of the drainage tube, improving its drainage efficiency.

[0021] A plate 265 is fixedly connected to the outer wall of the second fixing frame 256. One end of the plate 265 is slidably inserted into the limiting plate 264 to limit and support the limiting plate 264 and prevent the limiting plate 264 from rotating. A gripping plate 110 is fixedly connected to the top surface of the fixing plate 100. A gripping plate 310 is fixedly connected to one side of the outer wall of the clamping plate 300 to facilitate gripping of the fixing plate 100 and the clamping plate 300. The number of tooth grooves of the clamping plate 300 is (n+0.5) times the number of tooth grooves on the outer side of the second gear 255, so that the two vertical clamping plates 220 maintain different states after the first and second passage of the clamping plate 300. The distance between the axis of the second cylinder 257 and the axis of the second gear 255 is less than the distance between the axis of the first cylinder 253 and the axis of the first gear 252, which facilitates the reciprocating rotation of the first gear 252.

[0022] Working principle: When in use, insert the drainage tube between multiple horizontal clamps 210 and vertical clamps 220, insert the clamping plate 300 from the rear end of the slide rail 120, hold the gripper 110 to fix the fixing plate 100, and pull the clamping plate 300 forward to move the clamping plate 300 forward. When the clamping plate 300 passes the extrusion unit 200, the guide plate 320 presses the limiting plate 264 to the right, causing the limiting plate 264 to overcome the tension of the tension spring 263 and drive the insertion rod 262 to move to the right, thereby withdrawing from the limiting hole 2551. This allows the insertion rod 262 to release its restriction on the gear 255, and the clamping plate 300 engages with the gear 255. The clamping plate 300 moves forward, causing the gear 255 to rotate. The gear 255 drives the gear 1 252 to rotate reciprocally via the connecting rod 254. The reciprocating rotation of the gear 1 252 causes the two connecting rods 211 to move towards each other. When the two connecting rods 211 approach each other, they cause the two horizontal clamping plates 210 to move towards the middle. When one horizontal clamping plate 210 moves down, it pulls the vertical clamping plates 22 to both sides via the pull rope 243. 0, causing the two vertical clamping plates 220 to move away from each other against the elastic force of the compression spring 246, and the vertical clamping plates 220 and the horizontal clamping plates 210 move the same distance. The two horizontal clamping plates 210 exert lateral compression on the drainage tube. When the two horizontal clamping plates 210 move away from each other, the two vertical clamping plates 220 move towards the center under the elastic force of the compression spring 246, thereby causing the two vertical clamping plates 220 to vertically clamp the drainage tube. When the clamping plate 300 passes the gear 255, it drives the gear 255 to rotate n+0.5 revolutions. The gear 255 drives the horizontal clamping plates 210 and the vertical clamping plates 220 to repeatedly compress the drainage tube, causing the liquid in the drainage tube to surge, thereby clearing the drainage tube. Moreover, when the clamping plate 300 disengages from the gear 255, (such as...) Figure 10 (As shown in state b) The two vertical clamping plates 220 are in a separated state. The vertical clamping plates 220 are pushed towards the middle by the compression spring 246. The vertical clamping plates 220 pull the two horizontal clamping plates 210 apart through the pull rope 243, thereby causing gear one 252 to push gear two 255 through the connecting rod 254, causing gear two 255 to rotate to the position shown in state b. Figure 10 As shown in state a, after the clamping plate 300 passes, the two vertical clamping plates 220 automatically clamp the drainage tube, so that when the clamping plate 300 passes through the slide rail 120 from front to back, multiple squeezing units 200 squeeze the drainage tube horizontally and vertically and then clamp the drainage tube in sequence, thereby squeezing out the liquid originally stored in the drainage tube from the rear end of the drainage tube. Insert the clamping plate 300 again from the front end of the slide rail 120 and drag it to the rear end, so that the clamping plate 300 drives multiple extrusion units 200 to extrude the drainage tube from front to back in sequence. At this time, since the initial state of gear one 252 and gear two 255 is as follows... Figure 10 As shown in state a, after the card plate 300 passes through gear 255, gear 255 rotates n+2 revolutions, causing gear 255 and gear 1 252 to rotate to the position shown in state a. Figure 10As shown in state d, when transitioning from state d to state a, gear 255 rotates clockwise under the action of compression spring 246, causing the limiting hole 2551 to be inserted and engaged by the insertion rod 262 when passing through it. This causes gear 255 to remain in state c, where neither the two horizontal clamping plates 210 nor the two vertical clamping plates 220 clamp the drainage tube. This allows the drainage tube to recover from its compressed, flattened state to a cylindrical state, gradually recovering from the front end to the rear end. This allows the accumulated fluid to be drawn in from the front end of the drainage tube. This achieves the goal of squeezing the drainage tube to clear it while simultaneously squeezing and drawing in the accumulated fluid from the front end, thereby improving the drainage efficiency of the drainage tube.
