Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a drainage tube suspension and fixation device for a transport bed. Background Technology

[0002] Currently, various drainage tubes are widely used in clinical practice for various diseases. In level three and four surgeries, patients have different types and numbers of drainage tubes inserted to drain accumulated blood, gas, pus, and gastric contents. Observing the amount, color, and nature of the drainage fluid helps determine whether there has been postoperative bleeding and the patient's recovery status. Postoperatively, patients need to be observed in the post-anesthesia recovery room until their condition stabilizes before being returned to the ward. During this period, nurses in the recovery room must closely monitor their vital signs, and proper fixation of the drainage tubes is of paramount importance. Patients in the post-anesthesia recovery room lie on surgical transport beds. Currently, existing transport beds lack corresponding drainage tube fixation devices on both sides, failing to protect the connection between the drainage bag tube and the drainage tube. The connection between the drainage bag tube and the drainage tube is exposed, making it easy for the drainage bag tube and drainage tube to detach when the patient turns over, gets out of bed, or defecates, potentially leading to infection.

[0003] The technical problem this invention aims to solve is to design a suspension and fixing device for the drainage tube of a transfer bed that can protect the connection between the drainage bag tube and the drainage tube. Summary of the Invention

[0004] To overcome the drawback that the connection between the drainage bag tube and the drainage tube cannot be protected, leaving the connection exposed and prone to detachment during patient turning over, getting out of bed, or defecating, thus increasing the risk of infection, this invention provides a drainage tube suspension and fixing device for transport beds that can protect the connection between the drainage bag tube and the drainage tube.

[0005] To solve the above-mentioned technical problems, the present invention proposes the following technical solution: a suspension and fixing device for a drainage tube of a transfer bed, comprising a rounded corner box, a support platform, straps, a first limiting plate, nuts, screws, a guide rail, a connecting rod, a moving column, a sealing cover, a first cylinder, and a second limiting plate.

The rotating pressure plates are connected to each other on both the front and rear sides by a transmission wheel and a flat belt.

[0008] As a further preferred option, a disinfection mechanism is also included for disinfection when replacing the drainage bag. The disinfection mechanism includes a water tank, a movable frame, a piston plate, a water outlet pipe, a short nozzle, and an angled nozzle. The water tank is fixedly connected to both the front and rear sides of the right side of the rounded corner box. The movable frame is slidably connected to the top of the water tank. The movable frame contacts and cooperates with the connecting plate. The piston plate that slides inside the water tank is fixedly connected to the bottom of the movable frame. A water supply channel is opened on the left side of the support platform. The water supply channel is connected to the short nozzle and the angled nozzle. The water outlet pipe is connected to the top left side of the water tank. The water outlet pipe is connected to the water supply channel.

[0009] As a further preferred embodiment, it also includes a fixing mechanism for fixing the drainage tube. The fixing mechanism includes an angled plate, an arched plate, a parallel plate, a limiting rod, and a first return spring. An angled plate is fixedly connected to both the left and right sides of the bottom of the sealing cover. An arched plate is slidably connected to the support platform. Parallel plates are fixedly connected to both the front and rear sides of the top of the arched plate. The parallel plates are in contact with the adjacent angled plates. A first return spring located inside the support platform is fixedly connected between the lower part of the arched plate and the support platform.

[0010] As a further preferred embodiment, it also includes an auxiliary mechanism for assisting in the replacement of the drainage bag. The auxiliary mechanism includes a second cylinder, a connecting plate, a sliding frame, a rotating box, and a limiting cover. The second cylinder is fixedly connected to both the front and rear sides of the left side of the rounded corner box. The telescopic rods of the second cylinders are slidably connected to the left side of the rounded corner box. A connecting plate is fixedly connected to the telescopic rods of the second cylinders. A sliding frame is fixedly connected between the connecting plates. The sliding frame is slidably connected to the left side of the rounded corner box. A rotating box is fixedly connected to the sliding frame. A limiting cover for closing the rotating box is rotatably connected to the left side of the rotating box. A locking component for locking the limiting cover is provided on the right side of the rotating box.

[0011] As a further preferred embodiment, the locking assembly includes a double-ended plate, a limiting column, and a second return spring. The limiting columns are fixedly connected to both the front and rear sides of the right side of the rotating box. The double-ended plate, which is slidably connected to the rotating box, is slidably connected to the limiting column. The right side of the limiting cover has a through hole, and the double-ended plate is inserted into the through hole of the limiting cover. The second return spring is fixedly connected between the limiting column and the double-ended plate that slides on the limiting column.

[0012] As a further preferred embodiment, it also includes a buffer mechanism for cushioning the drainage bag tube when it is pulled. The buffer mechanism includes a second guide frame and a buffer spring. The second guide frame is slidably connected to the lower left side of the rounded corner box. The buffer spring is fixed between the right side of the second guide frame and the inner left wall of the rounded corner box. A limiting component for fixing the drainage bag tube is provided on the left side of the second guide frame.

[0013] As a further preferred embodiment, the limiting component includes a support frame, a fixing block, a connecting frame, a clamping block, and a pressure spring. The support frame is fixedly connected to the left side of the second guide frame, the fixing block is fixedly connected to the left side of the support frame, the connecting frame is slidably connected to the support frame, a pressure spring is fixedly connected between the connecting frame and the support frame, and a clamping block is fixedly connected to the left side of the connecting frame.

[0014] As a further preferred option, both the fixing block and the clamping block are arc-shaped, and the fixing block and the clamping block contact each other to form a hollow cylinder.

[0015] This invention has the following advantages: The rounded corner box and sealing cap work together to protect the connection between the drainage bag tube and the drainage tube, preventing the connection from being exposed and causing detachment and infection. The rotating pressure plate, in conjunction with the support platform, presses the drainage tube firmly, assisting medical staff in changing the drainage bag. This eliminates the need for medical staff to use hemostatic forceps to clamp the drainage tube, reducing the operational steps during drainage bag replacement. Furthermore, by connecting the flat plate to push the moving frame and piston plate upwards, disinfectant in the water tank is sprayed out through short and angled nozzles. Thus, every time the sealing cap is opened, the short and angled nozzles spray disinfectant to disinfect the rounded corner box, reducing the need for disinfection of the drainage tube. To prevent bacterial infection, an arched plate and support platform are used to fix the drainage tube, preventing it from detaching from the rounded corner box. A limiting cover plate and rotating box are used to fix and position the drainage bag tube, aligning it with the drainage tube. Then, a second cylinder drives the connecting plate back to its original position, allowing the drainage bag tube to extend into the rounded corner box, connecting the tube to the drainage tube. This further assists medical staff in changing the drainage bag, and the sealing cover does not need to be opened during replacement, further reducing the risk of bacterial infection. Clamping blocks and fixing blocks are used to further fix the drainage bag tube. When the drainage bag tube is pulled, a buffer spring cushions the pulling force, thus preventing the tube from detaching from the drainage tube. Attached Figure Description

Detailed Implementation

[0031] The present invention will be further described below with reference to specific embodiments. It should also be noted that, unless otherwise explicitly specified and limited, terms such as "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention based on the specific circumstances.

[0032] Example 1: Suspension and fixing device for drainage tubes of transfer bed, refer to Figures 1-4The system includes a rounded corner box 1, a support platform 101, straps 2, a first limiting plate 4, nuts 5, screws 6, a guide rail 7, a connecting rod 8, a moving column 81, a sealing cover 9, a first cylinder 10, and a second limiting plate 11. The support platform 101 is fixedly connected inside the rounded corner box 1. Three straps 2 are installed at the bottom of the rounded corner box 1 to secure it. Each of the three straps 2 has equally spaced insertion holes 3 at its rear. Each of the three straps 2 has a screw 6 installed at its front end, which is inserted into the corresponding insertion hole 3. Nuts 5 are threaded onto each of the three screws 6, and the first limiting plate 4 is rotatably connected to the nuts 5. The rounded corner box 1 has cylinders installed on both the front and rear sides of its upper part. There are two guide rails 7, and a movable column 81 is slidably connected between the two guide rails 7 on the same side. The upper front and rear sides of the rounded corner box 1 are fixedly connected to the second limiting plate 11. The two second limiting plates 11 are each equipped with a first cylinder 10. The telescopic rods of the two first cylinders 10 are in contact with the adjacent movable column 81. The two movable columns 81 have two square notches on their left and right sides. The four guide rails 7 are each equipped with a keyhole. The square notches of the two movable columns 81 are each matched with the lower part of the keyholes of the two adjacent guide rails 7. The left side of the two movable columns 81 is fixedly connected to a connecting rod 8. The connecting rod 8 is equipped with a sealing cover 9. The sealing cover 9 is used to close the rounded corner box 1.

[0033] In use, the rounded corner box 1 is fixed to the transfer bed by the strap 2. The screw 6 is inserted into the corresponding insertion hole 3 of the strap 2, and the first limiting plate 4 is clamped on the screw 6. The nut 5 is connected to the screw 6. Rotating the nut 5 fixes the nut 5 on the screw 6, thereby locking the strap 2. The first limiting plate 4 presses down on the strap 2 to prevent the strap 2 from curling. The drainage tube and the drainage bag tube are inserted into the left and right sides of the rounded corner box 1 respectively. The first cylinder 10 is activated, and the extension rod of the first cylinder 10 is extended to push the moving column 81 upward. The moving column 81 drives the sealing cover 9 upward through the connecting rod 8. When the moving column 81 moves upward to above the keyhole of the guide rail 7, the first cylinder 10 is closed, and the sealing cover 9 is manually rotated outward to open it. Then the drainage tube is inserted into the box. The tubes of the drainage bag and the drainage tube are connected. After the connection is completed, the sealing cover 9 is manually rotated inward. The first cylinder 10 is activated, and the telescopic rod of the first cylinder 10 is controlled to retract and reset. Then the first cylinder 10 is closed. The connecting rod 8, the moving column 81 and the sealing cover 9 move downward and reset due to gravity, closing the rounded corner box 1. This makes the square notch of the moving column 81 fit with the lower part of the keyhole of the two adjacent guide rails 7, which can limit the rotation of the moving column 81 and lock the sealing cover 9. This prevents the sealing cover 9 from being easily opened by unauthorized personnel, which would expose the connection between the tube of the drainage bag and the drainage tube. At the same time, the rounded corner box 1 and the sealing cover 9 work together to protect the connection between the tube of the drainage bag and the drainage tube, preventing the tube of the drainage bag and the drainage tube from detaching.

[0034] Example 2: Based on Example 1, referring to... Figure 1 , Figure 2, Figure 5 and Figure 6 It also includes a pressing mechanism for pressing the drainage tube. The pressing mechanism includes a connecting seat 12 and a rotating pressure plate 13. The top left and right sides of the support platform 101 are fixedly connected to the connecting seat 12, and the rotating pressure plate 13 is rotatably connected to both connecting seats 12. A synchronization component is provided in the middle of the rounded corner box 1. The synchronization component is used to drive the rotating pressure plate 13 to press the drainage tube.

[0035] The synchronization assembly includes a sliding plate 14, a connecting plate 15, a rack 16, a gear 17, a first guide frame 18, and a flat belt 19. The upper part of the rounded corner box 1 is slidably connected to the front and rear sides of the upper part of the sliding plate 1. The upper part of the two sliding plates 14 is sleeved on the adjacent moving column 81. The inner side of the two sliding plates 14 is fixedly connected to the connecting plate 15. The connecting plate 15 is located inside the rounded corner box 1. The left part of the support platform 101 is fixedly connected to the front and rear sides of the first guide frame 18. The two first guide frames 18 are equipped with racks 16. The two racks 16 are fixedly connected to the adjacent connecting plate 15. The left rotating pressure plate 13 is equipped with gears 17 on the front and rear sides. The two gears 17 mesh with the adjacent racks 16. The two rotating pressure plates 13 are connected to each other by a transmission wheel and a flat belt 19 on the front and rear sides.

[0036] When changing the drainage bag, to automatically compress the drainage tube and assist medical staff in changing the drainage bag, when the moving column 81 moves upward, the moving column 81 drives the sliding plate 14 to move upward, the sliding plate 14 drives the connecting plate 15 to move upward, the connecting plate 15 drives the rack 16 to move upward, and the rack 16 drives the left rotating pressure plate 13 to rotate downward through the gear 17. The left rotating pressure plate 13 drives the right rotating pressure plate 13 to rotate downward through the transmission wheel and flat belt 19, so that the rotating pressure plate 13 cooperates with the support platform 101 to compress the drainage tube, assisting in changing the drainage bag. When medical staff change the drainage bag, there is no need for them to use hemostatic forceps to clamp the drainage tube, reducing the operational procedures when changing the drainage bag. When the moving column 81 moves downward, it drives the sliding plate 14 to move downward, which in turn drives the connecting plate 15 to move downward. The connecting plate 15 then drives the rack 16 to move downward, and the rack 16 drives the left rotating pressure plate 13 to rotate upward and reset via the gear 17. The left rotating pressure plate 13 then drives the right rotating pressure plate 13 to rotate upward and reset via the transmission wheel and flat belt 19.

[0037] Reference Figure 1 , Figure 2 , Figure 7 and Figure 8It also includes a disinfection mechanism, which is used to disinfect when changing the drainage bag. The disinfection mechanism includes a water tank 21, a movable frame 22, a piston plate 23, a water outlet pipe 24, a short nozzle 25, and an angled nozzle 26. Water tanks 21 are installed on both the front and rear sides of the right side of the rounded corner box 1. The top of each water tank 21 is slidably connected to a movable frame 22, which is in contact with the connecting plate 15. The bottom of each movable frame 22 is fixedly connected to a piston plate 23, which slides inside the water tank 21. A water supply channel 201 is opened on the left side of the support platform 101, which is connected to the short nozzle 25 and the angled nozzle 26. The top left side of each of the two water tanks 21 is connected to a water outlet pipe 24, which is connected to the water supply channel 201.

[0038] When the sealing cover 9 is opened, in order to reduce bacterial infection of the drainage tube, an appropriate amount of disinfectant is added to the water tank 21. When the connecting plate 15 moves upward, the connecting plate 15 pushes the moving frame 22 upward, and the moving frame 22 drives the piston plate 23 upward, thereby pushing the disinfectant in the water tank 21 into the outlet pipe 24 and the water supply channel 201, and spraying it out through the short nozzle 25 and the angled nozzle 26. In this way, every time the sealing cover 9 is opened, the short nozzle 25 and the angled nozzle 26 will spray disinfectant to disinfect the rounded corner box 1, reducing bacterial infection of the drainage tube. When the disinfectant in the water tank 21 is used up, the piston plate 23 is manually reset downward through the moving frame 22.

[0039] Reference Figure 1 , Figure 2 , Figure 9 and Figure 10 It also includes a fixing mechanism for fixing the drainage tube. The fixing mechanism includes an angled plate 27, an arched plate 28, a parallel plate 29, a limiting rod, and a first return spring 30. An angled plate 27 is fixedly connected to the bottom left and right sides of the two sealing covers 9. Three arched plates 28 are slidably connected to the support platform 101. Parallel plates 29 are fixedly connected to the front and rear sides between the top of the three arched plates 28. The two parallel plates 29 are in contact with the two adjacent angled plates 27. Two first return springs 30 are installed between the lower part of the arched plates 28 and the support platform 101. The first return springs 30 are located inside the support platform 101.

[0040] After the drainage tube is inserted into the rounded corner box 1, to prevent the drainage tube from detaching from the rounded corner box 1, when the sealing cover 9 is rotated outward to open, the sealing cover 9 drives the inclined plate 27 to rotate outward, and then, under the action of the first reset spring 30, drives the arched plate 28 and the parallel plate 29 to move upward, so that medical personnel can insert or remove the drainage tube from the rounded corner box 1. When the sealing cover 9 is rotated inward to close, the sealing cover 9 drives the inclined plate 27 to rotate inward. When the inclined plate 27 contacts the parallel plate 29, it pushes the parallel plate 29 to move downward, and the parallel plate 29 drives the arched plate 28 to move downward. The first reset spring 30 is compressed, and the arched plate 28, together with the support platform 101, fixes the drainage tube to prevent the drainage tube from detaching from the rounded corner box 1.

[0041] Reference Figure 1 , Figure 2 , Figure 11 and Figure 12 It also includes an auxiliary mechanism for assisting in changing the drainage bag. The auxiliary mechanism includes a second cylinder 32, a connecting plate 33, a sliding frame 34, a rotating box 35, and a limiting cover plate 36. The second cylinder 32 is installed on both the front and rear sides of the left side of the rounded corner box 1. The telescopic rods of the two second cylinders 32 are slidably connected to the left side of the rounded corner box 1. The connecting plate 33 is fixedly connected to the telescopic rods of the two second cylinders 32. The sliding frame 34 is fixedly connected between the two connecting plates 33. The sliding frame 34 is slidably connected to the left side of the rounded corner box 1. The rotating box 35 is installed on the sliding frame 34. The left side of the rotating box 35 is rotatably connected to the limiting cover plate 36. The limiting cover plate 36 is used to close the rotating box 35. A locking component is provided on the right side of the rotating box 35. The locking component is used to lock the limiting cover plate 36.

[0042] The locking assembly includes a double-ended plate 37, a limiting column 38, and a second return spring 39. The limiting columns 38 are fixed to both the front and rear sides of the right side of the rotating box 35. The double-ended plate 37 is slidably connected to both limiting columns 38. The double-ended plate 37 is slidably connected to the rotating box 35. The right side of the limiting cover plate 36 has a through hole. The double-ended plate 37 is inserted into the through hole of the limiting cover plate 36. The second return spring 39 is installed between the two limiting columns 38 and the double-ended plate 37 that slides on the limiting columns 38.

[0043] To assist medical staff in changing the drainage bag, the second cylinder 32 is activated, controlling the extension rod of the second cylinder 32 to extend and move the connecting plate 33 to the left. The connecting plate 33 moves the sliding frame 34 to the left, and the sliding frame 34 moves the rotating box 35, the limiting cover plate 36, the double-ended plate 37, the limiting square post 38, and the second return spring 39 to the left out of the rounded corner box 1. Then, the second cylinder 32 is closed, and the double-ended plate 37 is manually moved outward. The second return spring 39 is compressed, thereby unlocking the limiting cover plate 36. Then, the limiting cover plate 36 is opened, and the tube of the drainage bag is placed into the rotating box 35. The limiting cover plate 36 is closed, and the double-ended plate 37 is released. Then, under the action of the second return spring 39, the double-ended plate 37 is moved inward and inserted into the through hole of the limiting cover plate 36, thereby limiting the drainage bag. The limiting cover 36 is locked, and the tube of the drainage bag is fixed and positioned by the limiting cover 36 in conjunction with the rotating box 35, so that the tube of the drainage bag is aligned with the drainage tube. Then, the second cylinder 32 is activated, and the telescopic rod of the second cylinder 32 is controlled to retract, which drives the connecting plate 33 to move to the right and reset. The connecting plate 33 drives the sliding frame 34 to move to the right and reset. The sliding frame 34 drives the rotating box 35, the limiting cover 36, the double-headed plate 37, the limiting square post 38 and the second reset spring 39 to move to the right and reset. This causes the tube of the drainage bag to extend into the rounded corner box 1. When the tube of the drainage bag contacts the drainage tube, the tube of the drainage bag is connected to the drainage tube, which further assists medical staff in changing the drainage bag. Moreover, the sealing cover 9 does not need to be opened when changing the drainage bag, which further reduces the risk of bacterial infection.

[0044] Reference Figure 1 , Figure 2 , Figure 13 and Figure 14 It also includes a buffer mechanism, which is used to buffer the drainage bag tube when it is pulled. The buffer mechanism includes a second guide frame 45 and a buffer spring 46. The second guide frame 45 is slidably connected to the lower left side of the rounded corner box 1. Two buffer springs 46 are installed between the right side of the second guide frame 45 and the inner left wall of the rounded corner box 1. A limit component is provided on the left side of the second guide frame 45. The limit component is used to fix the drainage bag tube.

[0045] The limiting assembly includes a support frame 40, a fixing block 41, a connecting frame 42, a clamping block 43, and a pressure spring 44. The second guide frame 45 is fixedly connected to the support frame 40 on the left side. The fixing block 41 is fixedly connected to the left side of the support frame 40. The connecting frame 42 is slidably connected to the support frame 40. A pressure spring 44 is installed between the connecting frame 42 and the support frame 40. The clamping block 43 is fixedly connected to the left side of the connecting frame 42. The fixing block 41 and the clamping block 43 are both arc-shaped. The fixing block 41 and the clamping block 43 contact each other to form a hollow cylinder.

[0046] To prevent the drainage bag tube from detaching from the drainage tube, manually move the connecting frame 42 to the left. The pressure spring 44 is compressed, and the connecting frame 42 drives the clamping block 43 to move to the left and separate from the fixing block 41. Pass the drainage bag tube through the clamping block 43 and the fixing block 41, release the connecting frame 42, and then, under the action of the pressure spring 44 resetting, drive the connecting frame 42 and the clamping block 43 to move to the right and reset. The clamping block 43, together with the fixing block 41, further fixes the drainage bag tube. When the drainage bag tube is pulled, the buffer spring 46 buffers the pulling force, thus preventing the drainage bag tube from detaching from the drainage tube.
