Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to an intelligent dressing changer for wound care after interventional surgery and its usage method. Background Technology

[0002] Post-interventional surgery wound care often requires medical staff to change the dressings regularly to accelerate wound healing and prevent infection.

[0003] The existing technology still has the following shortcomings when changing dressings:

[0004] 1. When changing dressings, medical staff need to remove the old dressing from the wound, then apply alcohol to the wound for disinfection, and then apply a new dressing. During this process, the wound is easily exposed to the outside air, which can easily lead to bacterial and viral contamination, increasing the risk of infection.

[0005] 2. Medical staff need to use trays to carry the necessary medical supplies. However, due to the heavy workload, especially when dealing with a large number of patients who require dressing changes, carrying trays full of medical parts undoubtedly increases their burden and thus affects their work efficiency.

[0006] To address the aforementioned issues, this invention proposes an intelligent dressing changer for wound care after interventional surgery and its usage method. Summary of the Invention

[0007] The purpose of this invention is to address the shortcomings of existing dressing changes, such as the ease with which wounds can become contaminated with bacteria and viruses and the need for medical personnel to carry trays full of medical components. This invention proposes an intelligent dressing changer for wound care after interventional surgery and its usage method.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A smart dressing changer for wound care after interventional surgery includes a hospital bed. Movable support plates are provided on both sides of the hospital bed. Lifting plates are slidably connected to the side of the two movable support plates that are close to each other. Two movable beams are slidably connected between the two lifting plates.

[0010] It also includes two rectangular slots, which are respectively set on the side of the two movable support plates that are close to each other. Each of the two rectangular slots is rotatably connected with a threaded rod, and each of the two rectangular slots is slidably connected with a nut block that is threaded to the adjacent threaded rod. The nut block is fixedly connected to the adjacent lifting plate. The threaded rod and the nut block cooperate to control the lifting of the lifting plate and the movable beam.

[0011] The covering structure, set between two movable beams, is used to cover the wound area where the dressing needs to be changed;

[0012] The sterilization structure, located between two movable beams, is used to disinfect and sterilize the space formed by the enclosure structure.

[0013] The storage structure, located between two movable beams, is used to store and place the corresponding medical components.

[0014] In one possible design, the covering structure includes two grooves located on adjacent sides of two movable beams. A first shielding nonwoven fabric strip is fixed within the two adjacent grooves on the two movable beams. A shielding component is fixed to the bottom of each of the two movable beams. Two second shielding nonwoven fabric strips are fixed to the adjacent sides of the two shielding components, with the two second shielding nonwoven fabric strips located at the bottom of the two first shielding nonwoven fabric strips. When the two first shielding nonwoven fabric strips, the second shielding nonwoven fabric strips, and the shielding components are unfolded, a replacement space is formed for subsequent dressing changes. A bidirectional screw drives the two movable beams to move to both sides, causing them to unfold. During the unfolding process, the first and second shielding nonwoven fabric strips unfold accordingly. Then, a motor drives a threaded rod to rotate, which, through a lifting plate, moves the movable beams downwards until the arc-shaped rubber strip conforms to the patient's body. Thus, the first and second shielding nonwoven fabric strips, along with the shielding components, work together to cover the wound, providing a sterile environment for subsequent dressing changes and preventing bacterial infection of the wound during dressing changes.

[0015] In one possible design, the sterilization structure includes two rotating grooves, each positioned on one side of two moving beams close to each other. The two rotating grooves are located between two first shielding non-woven fabric strips. Each rotating groove contains a liquid storage tube, with rotating shafts fixed at both ends. The rotating shafts are rotatably connected to the inner walls of the rotating grooves on both sides. Multiple electromagnetic atomizing nozzles are fixed on the side of each liquid storage tube close to each other, arranged in an alternating pattern to uniformly spray alcohol into the replacement space. Each rotating groove contains a reciprocating oscillating structure to drive the two liquid storage tubes to oscillate back and forth when the two moving beams move away from each other, ensuring the electromagnetic atomizing nozzles effectively sterilize and disinfect the replacement space. Injection hoses are fixedly inserted through the tops of both moving beams, with the bottom ends of the hoses extending into the corresponding liquid storage tubes and the top ends extending above the moving beams to inject alcohol into the storage tubes.

[0016] In one possible design, the reciprocating oscillating structure includes a rotating rod that rotates on the inner wall of one side of one of the rotating slots. One end of the rotating rod is fixed with a residual gear. A spur gear that intermittently meshes with the residual gear is fixedly sleeved on the outer wall of one of the rotating shafts. A torsion spring is sleeved on the outer wall of the other rotating shaft. Both ends of the torsion spring are fixedly connected to the inner wall of one side of the rotating slot and one end of the liquid storage tube, respectively, for driving the liquid storage tube to return to its original oscillation position. A fixed disc is fixedly sleeved on the outer wall of the rotating rod. A disc spring is also sleeved on the outer wall of the rotating rod. One end of the disc spring is fixedly connected to the outer wall of the rotating rod, and the other end of the disc spring is fixedly connected to the inner wall of one side of an adjacent rotating slot. The disc spring is used to drive the rotation. The rod returns to its original swing position. A pull rope is wound around the outer wall of the rotating rod, and the pull rope is located between the residual gear and the fixed plate. A fixed block is fixed to the end of the pull rope away from the rotating rod, and the fixed block is fixed to the bottom inner wall of another rotating groove. When the two moving beams move away from each other, the rotating rod can be driven to rotate through the cooperation of the fixed block and the pull rope. When the two moving beams move away from each other, the fixed block pulls the rotating rod and the residual gear to rotate through the pull rope. The residual gear and the spur gear mesh intermittently. Therefore, under the action of the residual gear, the spur gear and the torsion spring, the liquid storage tube can swing back and forth. The electromagnetic atomizing nozzle can evenly spray the alcohol in the alcohol tank into the replacement space to sterilize and disinfect the replacement space and avoid wound infection when changing dressings later.

[0017] In one possible design, the storage structure includes two storage boxes. Each of the two movable beams has two storage slots on its adjacent sides. The storage boxes are slidably disposed within two adjacent storage slots on their respective sides. Second metal contacts are fixedly embedded in the inner walls of the two adjacent sides of the two storage boxes. Limiting blocks extending into adjacent storage boxes are fixedly attached to the top inner walls of the four storage slots for limiting the movement of the storage boxes. A first metal contact is fixedly embedded in the side of the limiting block closest to the adjacent second metal contact, and the first metal contact engages with the second metal contact. A magnet is fixed to the other side of the limiting block, and magnetic fields are generated between adjacent magnets. The suction force is used to energize the LED light strips at the bottom of both movable beams, which provide illumination for the dressing change space. The first and second metal contacts are used to energize the LED light strips. When the two movable beams move away from each other, the storage box moves out of the corresponding two storage slots, allowing medical staff to take out the corresponding dressing change instruments from the storage box, greatly reducing the workload of medical staff. The limiting block limits the storage box to prevent it from falling out of the storage slot, and the cooperation of the first and second metal contacts can energize the LED light strips, thereby illuminating the wound and providing sufficient lighting conditions for medical staff to change dressings later.

[0018] In one possible design, both movable support plates have mounting grooves at their bottoms, and each of the two mounting grooves has multiple electric rollers located at the top of the bed to drive the movable support plates to move on the bed. The bottoms of both lifting plates are fixed with protective plates, and the two protective plates are slidably connected to one side of the adjacent movable support plates. The protective plates are used to cover the threaded rods in the rectangular grooves.

[0019] In one possible design, one side of one of the lifting plates is rotatably connected to a bidirectional lead screw via a base, and the bidirectional lead screw passes through two moving beams. The two moving beams are respectively threaded to the positive and negative thread sections of the bidirectional lead screw. A handle is fixed to one end of the bidirectional lead screw for driving the bidirectional lead screw to rotate.

[0020] In one possible design, the shielding component consists of an arc-shaped rubber strip, a non-woven fabric strip, and two vertical rubber strips. The tops of the two vertical rubber strips are fixedly connected to the bottom of the moving beam, and the two ends of the arc-shaped rubber strip are fixedly connected to the two vertical rubber strips respectively. The non-woven fabric strip is located between the arc-shaped rubber strip and the two vertical rubber strips to isolate the changing space from the outside world and provide a sterile environment for subsequent dressing changes.

[0021] In one possible design, one side of one of the movable beams is fixed with a circular shaft via a base. A flip-top plate is rotatably fitted onto the outer wall of the circular shaft. The flip-top plate is used to cover and envelop the two movable beams, blocking the gap between them. By rotating the flip-top plate, the two movable beams are enclosed and shielded, preventing external bacteria or dust from penetrating into the gap between them. This facilitates the patient's eating and leg support training on the flip-top plate later on.

[0022] This application discloses a method for using a smart dressing changer for wound care after interventional surgery, comprising the following steps:

[0023] S1. When the patient is in bed, the electric roller moving device is used to move the patient to the wound. The bidirectional screw is manually adjusted to unfold the moving beam and the first and second shielding non-woven fabric strips on it. Then the motor drives the threaded rod to lower the moving beam. The arc-shaped rubber strip fits the body. The first shielding non-woven fabric strip, the second shielding non-woven fabric strip and the shielding component together cover the wound to prevent infection.

[0024] S2. When the moving beam is deployed, the storage box slides out of the storage slot for easy access to dressing instruments. The limiting block ensures the stability of the storage box. The first metal contact piece and the second metal contact piece contact the LED light strip to provide sufficient lighting for medical staff to change dressings later.

[0025] S3. The unfolding of the moving beam also triggers the intermittent meshing of the residual gear and the spur gear, which drives the liquid storage tube to swing back and forth, and the electromagnetic atomizing nozzle evenly sprays alcohol disinfectant onto the replacement space.

[0026] S4. After changing the dressing, the moving beams are reassembled, the storage box is returned to its place, the coil spring resets the rotating rod, the pull rope is retracted, and the flip-top covers the gaps in the moving beams to prevent bacteria and dust from entering, while also facilitating the patient's diet and leg training.

[0027] Beneficial effects: In this invention, the same first shielding nonwoven fabric strip is fixed in two adjacent grooves, and shielding components are fixed at the bottom of both moving beams. Two second shielding nonwoven fabric strips are fixed on the side of the two shielding components that are close to each other, and the two second shielding nonwoven fabric strips are respectively located at the bottom of the two first shielding nonwoven fabric strips. The bidirectional screw drives the two moving beams to move to both sides, so that the two moving beams unfold. During the unfolding process, the first shielding nonwoven fabric strip and the second shielding nonwoven fabric strip unfold accordingly. The screw rod drives the moving beams to move down through the lifting plate until the arc-shaped rubber strip fits the patient's body. Then, the first shielding nonwoven fabric strip, the second shielding nonwoven fabric strip and the shielding components work together to cover the wound, providing a sterile environment for subsequent dressing changes and avoiding bacterial infection of the wound when changing dressings later.

[0028] In this invention, a residual gear is fixed to one end of the rotating rod, and a spur gear is fixedly sleeved on the outer wall of one of the rotating shafts. A pull rope is wound around the outer wall of the rotating rod, and a fixing block is fixed to the end of the pull rope away from the rotating rod. When the two moving beams move away from each other, the fixing block pulls the rotating rod and the residual gear to rotate through the pull rope. The residual gear and the spur gear mesh intermittently. Therefore, under the action of the residual gear, the spur gear, and the torsion spring, the liquid storage tube can swing back and forth. The electromagnetic atomizing nozzle can evenly spray the alcohol in the alcohol tank into the replacement space to sterilize and disinfect the replacement space, avoiding wound infection when changing dressings later.

[0029] In this invention, the storage box is slidably disposed in two adjacent storage slots on both sides. A second metal contact piece is fixedly embedded in the inner walls of the two storage boxes on their adjacent sides. A first metal contact piece is fixedly embedded in the side of the limiting block closest to the adjacent second metal contact piece. LED light strips are fixed to the bottom of both moving beams. When the two moving beams move away from each other, the storage box moves out of the corresponding two storage slots, allowing medical personnel to retrieve the corresponding dressing change instruments from the storage box, greatly reducing the workload of medical personnel. The limiting block prevents the storage box from detaching from the storage slot, and the cooperation of the first and second metal contact pieces energizes the LED light strip, providing sufficient lighting for medical personnel to change dressings later.

[0030] In this invention, a dressing change space can be quickly created at the wound site where the dressing needs to be changed, and alcohol can be sprayed on the dressing change space in a timely manner to sterilize and disinfect it, providing a sterile environment for subsequent dressing changes and avoiding wound infection during dressing changes.

[0044] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0045] Example 1: Refer to Figures 1-3 This device, relating to the field of medical device technology, comprises a hospital bed 1, with movable support plates 2 on both sides. Lifting plates 3 are mounted on the sides of these two movable support plates 2 that are close to each other via sliding connections such as slide rails, allowing the lifting plates 3 to slide up and down along the movable support plates 2. Simultaneously, two movable beams 9 are slidably connected between the two lifting plates 3 via sliding connections such as slide rails, allowing the movable beams 9 to slide horizontally between the lifting plates 3.

[0046] Reference Figure 2 and Figure 3To achieve the lifting and lowering of the lifting plate 3 and the moving beam 9, two rectangular slots 4 are respectively opened on the side of the two moving support plates 2 that are close to each other. A threaded rod 5 is rotatably connected to each rectangular slot 4, and a nut block 6, threadedly connected to the adjacent threaded rod 5, is slidably connected to each rectangular slot 4. These two nut blocks 6 are fixedly connected to the adjacent lifting plates 3. Therefore, when the threaded rod 5 rotates, due to the threaded connection, the nut block 6 will move along the axial direction of the threaded rod 5, thereby driving the lifting plate 3 and the moving beam 9 connected to it to rise and fall.

[0047] Reference Figure 2 and Figure 3 Each of the two movable support plates 2 has a mounting groove 7 at its bottom, and multiple electric rollers 8 are installed in the mounting groove 7. These electric rollers 8 are located on the top of the bed 1 and are used to drive the movable support plates 2 to move on the bed 1, thereby adjusting the position of the dressing changer. At the same time, a protective plate 40 is fixed to the bottom of each of the two lifting plates 3. The protective plate 40 is slidably connected to one side of the adjacent movable support plate 2 and is used to cover the threaded rod 5 in the rectangular groove 4 to prevent the threaded rod 5 from causing injury to the patient or medical staff during the lifting process.

[0048] Reference Figure 2 and Figure 4 A bidirectional lead screw 10 is fixedly connected to one side of the lifting plate 3 via a base. This bidirectional lead screw 10 is designed to be long enough to pass through two moving beams 9. Structurally, these two moving beams 9 are designed to be threadedly connected to the positive and negative threaded sections of the bidirectional lead screw 10, respectively. This means that when the bidirectional lead screw 10 rotates, due to the action of the positive and negative threads, the two moving beams 9 will move towards or away from each other along the length of the bidirectional lead screw 10. A handle 41 is fixed at one end of the bidirectional lead screw 10. The operator can drive the bidirectional lead screw 10 to rotate by rotating this handle 41, thereby controlling the two moving beams 9 to move closer or further apart to accommodate wound areas of different sizes.

[0049] Reference Figure 2 , Figure 4 , Figure 6 and Figure 7To achieve wound coverage for dressing changes, a covering structure was designed. Specifically, two grooves 18 are provided on the side of the two moving beams 9 that are close to each other, and the same first covering non-woven fabric strip 19 is fixed in the two adjacent grooves 18 within the two moving beams 9. Simultaneously, covering components 20 are fixed at the bottom of both moving beams 9, and two second covering non-woven fabric strips 21 are fixed on the side of these two covering components 20 that are close to each other, with these two second covering non-woven fabric strips 21 located at the bottom of the two first covering non-woven fabric strips 19. Therefore, when the two moving beams 9 unfold to both sides, the two first covering non-woven fabric strips 19 and the two second covering non-woven fabric strips 21 also unfold accordingly, forming a changing space together with the covering components 20 for subsequent dressing changes. To achieve the unfolding and retraction of the moving beams 9, a bidirectional lead screw 10 is used as the drive, and the rotation of the bidirectional lead screw 10 drives the two moving beams 9 to move to both sides or retract towards the center.

[0050] Specifically, the patient lies flat on bed 1, aligning the wound requiring dressing change with the center between the two moving beams 9. Then, the drive mechanism of the bidirectional lead screw 10 is activated, causing it to rotate and drive the two moving beams 9 to unfold to both sides. During this unfolding process, the first and second non-woven fabric covering strips 19 and 21 also unfold and come into contact with the patient's body. Next, the motor drives the threaded rod 5 to rotate, causing the lifting plate 3 and the connected moving beams 9 to move downwards until the curved rubber strip 22 fits against the patient's body. At this point, the first and second non-woven fabric covering strips 19 and 21, along with the covering component 20, work together to cover the wound, providing a sterile environment for subsequent dressing changes.

[0051] Reference Figure 4 , Figure 6 and Figure 9To achieve the sterilization and disinfection function, a sterilization structure was designed. Specifically, two rotating grooves 25 are respectively set on the side where the two moving beams 9 are close to each other, and these two rotating grooves 25 are located between the two first shielding non-woven fabric strips 19. A liquid storage tube 26 is set in each rotating groove 25, and rotating shafts 27 are fixed at both ends of the liquid storage tube 26. These two rotating shafts 27 are rotatably connected to the inner walls on both sides of the rotating groove 25. Therefore, the liquid storage tube 26 can swing within the rotating groove 25. Multiple electromagnetic atomizing nozzles 28 are fixed on the side where the two liquid storage tubes 26 are close to each other, and the multiple electromagnetic atomizing nozzles 28 on the two liquid storage tubes 26 are arranged alternately. Thus, when alcohol is injected into the liquid storage tube 26, the electromagnetic atomizing nozzles 28 can atomize the alcohol and spray it evenly into the replacement space, thereby achieving sterilization and disinfection of the replacement space. To achieve the reciprocating oscillation of the liquid storage tube 26, a reciprocating oscillation structure is provided in both rotating slots 25 to drive the two liquid storage tubes 26 to reciprocate oscillate when the two moving beams 9 move away from each other. At the same time, an injection hose 31 is fixedly inserted through the top of each of the two moving beams 9. The bottom end of the injection hose 31 extends into the corresponding liquid storage tube 26, and the top end of the injection hose 31 extends above the moving beam 9 to facilitate the injection of alcohol into the liquid storage tube 26.

[0052] Reference Figure 6 , Figure 9 and Figure 10 The reciprocating oscillating structure includes a rotating rod 32 rotatably mounted on the inner wall of one side of one of the rotating slots 25. A residual gear 33 is fixed to one end of the rotating rod 32, while a spur gear 30, intermittently meshing with the residual gear 33, is fixedly sleeved on the outer wall of one of the rotating shafts 27. A torsion spring 29 is sleeved on the outer wall of the other rotating shaft 27, with both ends of the torsion spring 29 fixedly connected to the inner wall of one side of the rotating slot 25 and one end of the liquid storage tube 26, respectively. This design allows the liquid storage tube 26 to reset and begin the next oscillation after completing one oscillation. Furthermore, a fixed disc 34 is fixedly sleeved on the outer wall of the rotating rod 32, and a disc spring 35 is sleeved on its outer wall. One end of the disc spring 35 is fixedly connected to the outer wall of the rotating rod 32, and the other end is fixedly connected to the inner wall of one side of the adjacent rotating slot 25, allowing the rotating rod 32 to reset and begin the next oscillation after completing one rotation. A pull rope 36 is wound around the outer wall of the rotating rod 32, between the residual gear 33 and the fixed disc 34. A fixing block 37 is fixed to the end of the pull rope 36 away from the rotating rod 32, and the fixing block 37 is fixed to the bottom inner wall of another rotating groove 25. When the two moving beams 9 move away from each other, the rotating rod 32 can be driven to rotate by the cooperation of the fixing block 37 and the pull rope 36.

[0053] Specifically, the fixing block 37 pulls the rotating rod 32 and the residual gear 33 to rotate via the pull rope 36. Since the residual gear 33 intermittently meshes with the spur gear 30, the liquid storage tube 26 can reciprocate under the combined action of the residual gear 33, the spur gear 30, and the torsion spring 29. The electromagnetic atomizing nozzle 28 can evenly spray the alcohol in the alcohol tank into the dressing change space, thereby sterilizing and disinfecting the dressing change space and preventing wound infection during subsequent dressing changes.

[0054] Reference Figure 4 and Figure 5 In addition, the intelligent dressing changer also includes a storage structure for storing instruments needed for dressing changes. This storage structure includes two storage boxes 12, and two storage slots 11 are provided on each side of the two moving beams 9 that are close to each other. The two sides of the storage boxes 12 are slidably disposed within the two adjacent storage slots 11. Second metal contact pieces 15 are fixedly embedded in the inner walls of the two adjacent sides of the two storage boxes 12. Limiting blocks 13 extending into the adjacent storage boxes 12 are fixedly fixed to the top inner walls of the four storage slots 11 to limit the storage boxes 12 and prevent them from detaching from the storage slots 11. A first metal contact piece 14 is fixedly embedded in the side of the limiting block 13 near the adjacent second metal contact piece 15, and the first metal contact piece 14 cooperates with the second metal contact piece 15. A magnet 16 is fixed to the other side of the limiting block 13, and magnetic attraction is generated between adjacent magnets 16. LED light strips 17 are fixed to the bottom of the two moving beams 9 to provide illumination for the changing space. When the first metal contact 14 comes into contact with the second metal contact 15, the LED light strip 17 is powered on, thereby illuminating the wound and providing sufficient lighting for medical staff to change dressings later.

[0055] Reference Figure 6 and Figure 7 The shielding component 20 consists of an arc-shaped rubber strip 22, a non-woven fabric strip 24, and two vertical rubber strips 23. The tops of the two vertical rubber strips 23 are fixedly connected to the bottom of the moving beam 9. The two ends of the arc-shaped rubber strip 22 are fixedly connected to the two vertical rubber strips 23 respectively. The non-woven fabric strip 24 is located between the arc-shaped rubber strip 22 and the two vertical rubber strips 23, and is used to isolate the changing space from the outside world, providing a sterile environment for subsequent dressing changes. The non-woven fabric strip 24 has good air permeability and isolation performance, which can effectively isolate the changing space from the outside world and provide a sterile environment for subsequent dressing changes.

[0056] Through the above design, this intelligent dressing changer for post-interventional wound care can not only sterilize and disinfect the wound before changing the dressing, but also provide sufficient lighting and convenient storage and retrieval of the necessary dressing change instruments, greatly reducing the workload of medical staff.

[0057] Example 2: Reference Figure 11 and Figure 12 An improvement upon Embodiment 1 is made as follows: One side of one of the movable beams 9 is further secured to a circular shaft 38 via a base. A flip-top plate 39 is rotatably fitted onto the outer wall of the circular shaft 38. The size and shape of the flip-top plate 39 are designed to completely cover and enclose both movable beams 9, while simultaneously concealing the gap between them.

[0058] In actual use, the operator can rotate the flip cover 39 to cover the two moving beams 9, thereby completely covering the two moving beams 9 and the gap between them.

[0059] The flip-top 39 design not only enhances the sealing of the sterile environment but also provides convenience for patients. For example, after changing dressings, patients can eat or drink on the flip-top 39, avoiding soiling the bed or wound area. Simultaneously, the flip-top 39 can also serve as a platform for leg support training, assisting patients in their rehabilitation exercises.

[0060] A method for using a smart dressing changer for wound care after interventional surgery includes the following steps:

[0061] S1. The patient lies on the hospital bed 1. When the dressing needs to be changed, the electric roller 8 drives the movable support plate 2 and the movable beam 9 to move to the patient's wound position. Then, the double-acting screw 10 is manually rotated. The double-acting screw 10 drives the two movable beams 9 to move to both sides, so that the two movable beams 9 unfold. During the unfolding process, the first shielding non-woven fabric strip 19 and the second shielding non-woven fabric strip 21 unfold accordingly. Then, the motor drives the threaded rod 5 to rotate. The threaded rod 5 drives the movable beam 9 to move down through the lifting plate 3 until the arc-shaped rubber strip 22 fits against the patient's body. Then, the first shielding non-woven fabric strip 19, the second shielding non-woven fabric strip 21 and the shielding component 20 work together to cover the wound and prevent the wound from being infected with bacteria when changing the dressing later.

[0062] S2. Additionally, when the two moving beams 9 move away from each other, the storage box 12 moves out of the corresponding two storage slots 11, thereby enabling medical staff to take out the corresponding dressing change instruments from the storage box 12, greatly reducing the workload of medical staff. The limiting block 13 limits the storage box 12 to prevent it from falling out of the storage slot 11, and the cooperation between the first metal contact 14 and the second metal contact 15 can power the LED light strip 17, thereby illuminating the wound and providing sufficient lighting conditions for medical staff to change dressings later.

[0063] S3. In addition, when the two moving beams 9 move away from each other, the fixed block 37 pulls the rotating rod 32 and the residual gear 33 to rotate through the pull rope 36. The residual gear 33 intermittently meshes with the spur gear 30. Therefore, under the action of the residual gear 33, the spur gear 30 and the torsion spring 29, the liquid storage tube 26 can swing back and forth. The electromagnetic atomizing nozzle 28 can evenly spray the alcohol in the alcohol box into the replacement space to sterilize and disinfect the replacement space and avoid wound infection when changing dressings later.

[0064] S4. After the replacement is completed, the two moving beams 9 move closer to each other, and the storage box 12 is stored in the storage slot 11. The coil spring 35 drives the rotating rod 32 to return to its original swing position. The rotating rod 32 rewinds the pull rope 36 until the two moving beams 9 are in contact. To prevent external bacteria or dust from penetrating into the gap between the two moving beams 9, the flip cover 39 is rotated to cover and shield the two moving beams 9, making it easier for the patient to eat and perform leg support exercises on the flip cover 39 later.

[0065] However, as is well known to those skilled in the art, the working principles and wiring methods of the LED light strip 17, the electric roller 8 and the electromagnetic atomizing nozzle 28 are commonplace and are all conventional methods or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0066] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
