[0002] Wound care after interventional surgery often requires medical staff to change the wound dressing regularly to accelerate wound healing and avoid infection.

[0003] The prior art still has the following disadvantages when changing dressings:

[0004] 1. When changing the dressing, medical staff need to remove the original dressing from the wound, then apply alcohol to the wound for disinfection, and apply the new dressing. During this process, the wound is easily exposed to the outside air, which can easily cause the wound to be contaminated with bacteria and viruses, increasing the risk of infection.

[0005] 2. Medical staff need to use trays to carry the necessary medical supplies. However, due to the busy work, especially when facing a large number of patients who need to change dressings, carrying trays full of medical parts will undoubtedly increase their burden and affect their work efficiency.

[0044] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0045] Example 1: Reference Figure 1-Figure 3 , a changer, relates to the technical field of medical devices, and its structure includes a bed 1, and both sides of the bed 1 are provided with movable support plates 2. The two movable support plates 2 are both provided with a lifting plate 3 on the side close to each other through a sliding connection structure such as a slide rail, so that the lifting plate 3 can slide up and down along the movable support plate 2. At the same time, between the two lifting plates 3, two movable beams 9 are slidably connected through a sliding connection structure such as a slide rail, so that the movable beam 9 can slide horizontally between the lifting plates 3.

[0046] Reference Figure 2 and Figure 3In order to realize the lifting and lowering of the lifting plate 3 and the moving beam 9, two rectangular grooves 4 are respectively opened on the side where the two moving support plates 2 are close to each other. In each rectangular groove 4, a threaded rod 5 is rotatably connected, and in each rectangular groove 4, a nut block 6 threadedly connected to the adjacent threaded rod 5 is slidably connected. The two nut blocks 6 are respectively fixedly connected to the adjacent lifting plates 3. Therefore, when the threaded rod 5 rotates, due to the effect of 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 thereto to rise and fall.

[0047] Reference Figure 2 and Figure 3 , a mounting groove 7 is provided at the bottom of the two movable support plates 2, and a plurality of electric rollers 8 are provided 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, so as to adjust the position of the dressing changer. At the same time, a protective plate 40 is fixed at the bottom of the two lifting plates 3, and the protective plate 40 is slidably connected to one side of the adjacent movable support plate 2, and is used to shield the threaded rod 5 in the rectangular groove 4, so as to prevent the threaded rod 5 from causing harm to the patient or medical staff during the lifting process.

[0048] Reference Figure 2 and Figure 4 A bidirectional screw 10 is fixedly connected to one side of the lifting plate 3 through a base. The bidirectional screw 10 is designed to be long enough to pass through the two moving beams 9. The two moving beams 9 are structurally designed to be threadedly connected to the positive and negative thread segments of the bidirectional screw 10 respectively. This means that when the bidirectional screw 10 rotates, due to the action of the positive and negative threads, the two moving beams 9 will move toward or away from each other along the length direction of the bidirectional screw 10. At one end of the bidirectional screw 10, a handle 41 is fixed. The operator can drive the bidirectional screw 10 to rotate by rotating the handle 41, thereby controlling the two moving beams 9 to move closer or farther away from each other to adapt to wound areas of different sizes.

[0049] Reference Figure 2 , Figure 4 , Figure 6 and Figure 7In order to achieve the shielding of the wound position to be replaced with the dressing, a covering structure is designed. Specifically, two grooves 18 are set on the side where the two moving beams 9 are close to each other, and the same first shielding non-woven fabric strip 19 is fixed in the two grooves 18 close to each other in the two moving beams 9. At the same time, a shielding component 20 is fixed at the bottom of the two moving beams 9, and two second shielding non-woven fabric strips 21 are fixed on the side where the two shielding components 20 are close to each other, and the two second shielding non-woven fabric strips 21 are respectively located at the bottom of the two first shielding non-woven fabric strips 19. Therefore, when the two moving beams 9 are unfolded to both sides, the two first shielding non-woven fabric strips 19 and the two second shielding non-woven fabric strips 21 will also be unfolded, and together with the shielding component 20, a replacement space is formed for the later replacement of the dressing. In order to realize the expansion and retraction of the moving beams 9, a bidirectional screw 10 is used as a drive, and the two moving beams 9 are driven to move to both sides or retract to the middle by the rotation of the bidirectional screw 10.

[0050] Specifically, the patient lies flat on the bed 1, and aligns the position of the wound that needs to change the dressing with the center position between the two moving beams 9. Then, the driving device of the bidirectional screw 10 is started to rotate the bidirectional screw 10 and drive the two moving beams 9 to expand to both sides. During the expansion process, the first shielding non-woven fabric strip 19 and the second shielding non-woven fabric strip 21 will also expand and contact the patient's body. Next, the motor is started to drive the threaded rod 5 to rotate and drive the lifting plate 3 and the moving beam 9 connected thereto to move downward until the arc-shaped rubber strip 22 fits the patient's body. At this time, the first shielding non-woven fabric strip 19, the second shielding non-woven fabric strip 21 and the shielding component 20 can cooperate to cover the wound and provide a sterile environment for the subsequent dressing change.

[0051] Reference Figure 4 , Figure 6 and Fig. 9In order to achieve the function of sterilization and disinfection, a sterilization structure is designed. Specifically, two rotating grooves 25 are respectively arranged on the side where the two moving beams 9 are close to each other, and the two rotating grooves 25 are located between the two first shielding non-woven fabric strips 19. In each rotating groove 25, a liquid storage tube 26 is arranged, and a rotating shaft 27 is fixed at both ends of the liquid storage tube 26, and the two rotating shafts 27 are respectively rotatably connected to the inner walls of the two sides of the rotating groove 25. Therefore, the liquid storage tube 26 can swing in the rotating groove 25. On the side where the two liquid storage tubes 26 are close to each other, a plurality of electromagnetic atomizing nozzles 28 are fixed, and the plurality of electromagnetic atomizing nozzles 28 on the two liquid storage tubes 26 are staggered. In this way, when alcohol is injected into the liquid storage tube 26, the electromagnetic atomizing nozzle 28 can atomize the alcohol and spray it evenly into the replacement space, thereby achieving sterilization and disinfection of the replacement space. In order to realize the reciprocating swing of the liquid storage tube 26, a reciprocating swing structure is provided in the two rotating grooves 25, which is used to drive the two liquid storage tubes 26 to reciprocate when the two moving beams 9 move away from each other. At the same time, a liquid injection hose 31 is fixedly passed through the top of the two moving beams 9, and the bottom end of the liquid injection hose 31 is fixedly extended into the corresponding liquid storage tube 26, and the top end of the liquid injection hose 31 extends above the moving beam 9, so as to facilitate the injection of alcohol into the liquid storage tube 26.

[0052] Reference Figure 6 , Fig. 9 and Fig.10 The reciprocating swing structure includes a rotating rod 32 rotatably arranged on the inner wall of one side of one of the rotating grooves 25. A residual gear 33 is fixed on one end of the rotating rod 32, and 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, and the two ends of the torsion spring 29 are respectively fixedly connected to the inner wall of one side of the rotating groove 25 and one end of the liquid storage tube 26. This design is used to drive the liquid storage tube 26 to reset and perform the next swing after completing one swing. In addition, a fixed disk 34 is also fixedly sleeved on the outer wall of the rotating rod 32, and a coil spring 35 is sleeved on its outer wall. One end of the coil 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 groove 25, which is used to drive the rotating rod 32 to reset and perform the next rotation after completing one rotation. A pull rope 36 is wound around the outer wall of the rotating rod 32, located between the residual gear 33 and the fixed disk 34. A fixing block 37 is fixed to one 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 fixed block 37 pulls the rotating rod 32 and the residual gear 33 to rotate through the pull rope 36. Since the residual gear 33 is intermittently meshed with the spur gear 30, the liquid storage tube 26 can be reciprocated by 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 replacement space, thereby sterilizing and disinfecting the replacement space to avoid wound infection when changing the dressing later.

[0054] Reference Figure 4 and Figure 5 In addition, the intelligent dressing changer also includes a storage structure for storing the equipment required for changing the dressing. The storage structure includes two storage boxes 12, and two storage slots 11 are provided on the side where the two moving beams 9 are close to each other, and the two sides of the storage box 12 are respectively slidably arranged in the two adjacent storage slots 11. The inner walls of the two storage boxes 12 close to each other are fixedly embedded with second metal contacts 15. The top inner walls of the four storage slots 11 are fixed with limit blocks 13 extending into the adjacent storage boxes 12, which are used to limit the storage boxes 12 to prevent them from escaping from the storage slots 11. The side of the limit block 13 close to the adjacent second metal contact 15 is fixedly embedded with a first metal contact 14, and the first metal contact 14 cooperates with the second metal contact 15. A magnet 16 is fixed on the other side of the limit block 13, and a magnetic attraction is generated between the two adjacent magnets 16. The bottom of the two moving beams 9 is fixed with an LED light strip 17 to provide lighting for the replacement space. When the first metal contact piece 14 contacts the second metal contact piece 15 , the LED light strip 17 can be powered on, thereby illuminating the wound and providing sufficient lighting conditions for medical staff to change the dressing at a later stage.

[0055] Reference Figure 6 and Figure 7 The shielding component 20 is composed 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, and 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 replacement space from the outside world and provide a sterile environment for subsequent dressing replacement. The non-woven fabric strip 24 has good air permeability and isolation performance, and can effectively isolate the replacement space from the outside world and provide a sterile environment for subsequent dressing replacement.

[0056] Through the above design, the intelligent dressing changer for wound care after interventional surgery can not only sterilize and disinfect the wound before changing the dressing, but also provide sufficient lighting conditions and conveniently store and remove the required dressing changing instruments, greatly reducing the workload of medical staff.

[0057] Example 2: Reference Fig.11 and Fig.12 , based on the improvement of embodiment 1: In addition, a round shaft 38 is fixed to one side of one of the moving beams 9 through a base. A flap plate 39 is rotatably sleeved on the outer wall of the round shaft 38. The size and shape of the flap plate 39 are designed to completely cover and envelop the two moving beams 9, while shielding the gap between the two moving beams 9.

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

[0059] The design of the flap 39 not only enhances the closedness of the sterile environment, but also provides convenience for the patient. For example, after changing the dressing, the patient can eat and drink on the flap 39 to avoid soiling the bed surface or the wound area. At the same time, the flap 39 can also be used as a platform for leg support training to help patients perform rehabilitation training.

[0060] A method for using an intelligent dressing changer for wound care after interventional surgery comprises the following steps:

[0061] S1. The patient lies on the 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, and then the bidirectional screw rod 10 is manually rotated, and the bidirectional screw rod 10 drives the two movable beams 9 to move to both sides, so that the two movable beams 9 are unfolded, and the first shielding non-woven fabric strip 19 and the second shielding non-woven fabric strip 21 are unfolded during the unfolding process. Then, the motor drives the threaded rod 5 to rotate, and the threaded rod 5 drives the movable beam 9 to move downward through the lifting plate 3 until the arc-shaped rubber strip 22 fits the patient's body, and then the first shielding non-woven fabric strip 19, the second shielding non-woven fabric strip 21 and the shielding component 20 cooperate to cover the wound, so as to prevent the wound from being infected with bacteria when the dressing is changed later;

[0062] S2. In addition, when the two moving beams 9 move away from each other, the storage box 12 is moved out of the corresponding two storage slots 11, so that the medical staff can take out the corresponding dressing replacement equipment from the storage box 12, which greatly reduces the workload of the medical staff. The limit block 13 limits the storage box 12 to prevent the storage box 12 from being separated from the storage slot 11, and the cooperation of the first metal contact sheet 14 and the second metal contact sheet 15 can energize the LED light strip 17, so as to illuminate the wound, providing sufficient lighting conditions for the medical staff to change the dressing in the later stage;

[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, and the residual gear 33 is intermittently meshed 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, and the electromagnetic atomizing nozzle 28 can evenly spray the alcohol in the alcohol tank into the replacement space to sterilize and disinfect the replacement space, thereby avoiding wound infection when changing the dressing later;

[0064] S4. After the replacement is completed, the two movable beams 9 are moved 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 swing, and the rotating rod 32 rewinds the pull rope 36 until the two movable beams 9 are fitted together. In order to prevent external bacteria or dust from penetrating into the gap between the two movable beams 9, the flap plate 39 is rotated at this time to cover and shield the two movable beams 9, so that the patient can eat and drink on the flap plate 39 and perform leg support training in the later stage.

[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 conventional means or common knowledge, and will not be elaborated here. Those skilled in the art can make any optional selections according to their needs or convenience.

[0066] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
