Detailed implementation manners

[0029] First of all, it should be pointed out that in different described embodiments, the same components are provided with the same reference numerals or the same component names. Among them, the disclosure contained throughout the specification can be meaningfully transferred to the same components with the same reference numerals or the same component names. The positional descriptions selected in the specification, such as up, down, lateral, etc., also refer to the directly described and illustrated drawings and are meaningfully transferred to the new positions when the positions change.

[0030] Example: A surgical nursing dressing change device, please refer to Figures 1 - 7As shown in the figure, it includes a housing 1 and a cover plate 3 rotatably connected to the housing 1 symmetrically left and right. On the lower parts of the left and right outer sides of the housing 1, limiting plates 2 are fixedly connected symmetrically front and back. When the cover plate 3 contacts the limiting plates 2, the limiting plates 2 can support and limit the cover plate 3. It also includes a moving component, a first clamp 51, a fixing plate 6, a fastening bolt 7, an annular plate 8, a mounting ring 9, an iron plate 10, a thickness sensor 11, a return spring 12, an electromagnet 13, a second clamp 14, and a disinfection component. A moving component is arranged inside the housing 1. Fixing plates 6 are fixedly connected symmetrically front and back on the moving component. Fastening bolts 7 are installed at positions where the front and rear fixing plates 6 are close to each other. The fastening bolts 7 can place and limit the gauze. Electromagnets 13 are fixedly connected symmetrically up and down on the left side surfaces of the front and rear fixing plates 6. A first clamp 51 is fixedly connected to the upper left side of the rear inner surface of the housing 1. An annular plate 8 is slidably connected between the front and rear sides inside the housing 1. Two return springs 12 are connected between the rear side of the left side surface of the annular plate 8 and the rear side of the left side surface inside the housing 1. The inner side of the annular plate 8 is rotatably connected to a mounting ring 9 along the circumferential direction. Two iron plates 10 are fixedly connected to the inner side of the mounting ring 9. The right sides of the upper and lower iron plates 10 are in magnetic contact with the upper and lower electromagnets 13 respectively. A second clamp 14 is fixedly connected to the middle of the front side inside the mounting ring 9. Thickness sensors 11 are installed at the tops of the front and rear fixing plates 6. The thickness sensors 11 correspond to the fastening bolts 7. The thickness sensors 11 are electrically connected to the electromagnets 13. The thickness sensors 11 are used to control the electromagnets 13 to cut off the power. Due to the action of the return spring 12, the annular plate 8 drives the second clamp 14 to move leftward through the mounting ring 9. The second clamp 14 pulls out the head end of the spare gauze, so that the fastening bolt 7 drives the spare gauze to rotate and continue to wrap. A disinfection component is arranged between the housing 1 and the electric moving ring 4. When the disinfection component operates, the disinfection component can disinfect the inner side of the used housing 1.

[0031] Please refer to Figure 3 As shown in the figure, the moving component includes an electric moving ring 4 and an electric rotating ring 5. An electric moving ring 4 is horizontally installed inside the housing 1. The electric moving ring 4 is located on the right side of the annular plate 8. An electric rotating ring 5 is installed inside the electric moving ring 4. The inner side of the electric rotating ring 5 is fixedly connected to the front and rear fixing plates 6. The electric rotating ring 5 can drive the fixing plates 6 to rotate.

[0032] Please refer to Figure 6 and Figure 7As shown in the figure, the disinfection component includes an annular nozzle 15, a frame 151, an ultraviolet disinfection lamp 152, a tensioning component, and a hose 156. An annular nozzle 15 is fixedly connected to the right side surface of the electric moving ring 4 along the circumference. The annular nozzle 15 can spray disinfectant liquid to disinfect the inner side of the housing 1. A frame 151 is fixedly connected to the middle of the front side surface of the housing 1. A hose 156 is fixedly inserted through the right side of the front side surface of the frame 151. The liquid outlet end of the hose 156 slidably penetrates through the front side of the housing 1 and is connected to the front side of the annular nozzle 15. A tensioning component is arranged on the frame 151. When the tensioning component operates, the tensioning component can tighten the hose 156 to prevent the hose 156 from loosening and knotting. The upper part of the housing 1 is symmetrically and fixedly inserted with ultraviolet disinfection lamps 152 in the front and back. The ultraviolet disinfection lamps 152 can further disinfect the inside of the housing 1. The tensioning component includes a movable rod 153, a guide wheel 154, and a connecting spring 155. The top and bottom of the frame 151 are slidably inserted with movable rods 153 at equal intervals. The movable rods 153 on the upper and lower sides are arranged staggeredly. The end of the movable rod 153 located inside the frame 151 is rotatably connected to a guide wheel 154. The hose 156 bypasses the guide wheel 154. The guide wheel 154 can tighten and guide the hose 156. A connecting spring 155 is connected between the movable rod 153 and the inner side surface of the frame 151.

[0033] Initially, the hose 156 is externally connected to the disinfectant solution. First, pull the cover plate 3 to swing downward to open it. The cover plate 3 swings downward by ninety degrees and contacts the limit plate 2. The limit plate 2 supports and limits the cover plate 3. Subsequently, twist the fastening bolt 7 off the fixed plate 6, put two rolls of gauze on the front and rear fixed plates 6 respectively, and then twist the fastening bolt 7 back to its original position to limit the gauze. The thickness sensor 11 contacts the gauze, start the thickness sensor 11 to detect the amount of the gauze. Then pull the head end of the rear gauze to move to the first clamp 51 and be clamped, pull the head end of the front gauze to move to the second clamp 14 and be clamped. Subsequently, the patient can pass the upper limb through the housing 1 and place it between the left and right cover plates 3. Then start the electric rotating ring 5 to rotate, driving the fixed plate 6 to rotate. The fixed plate 6 rotates to drive the front and rear gauzes to rotate. The rear gauze rotates and winds around the patient's wound for dressing. At the same time, the rotation of the rear fixed plate 6 drives the iron plate 10 to rotate through the electromagnet 13. The rotation of the iron plate 10 drives the mounting ring 9 to rotate. The rotation of the mounting ring 9 drives the second clamp 14 to rotate. The rotation of the second clamp 14 drives the head end of the gauze to rotate. The second clamp 14 rotates synchronously with the front gauze, and the front gauze will not wind around the patient's wound. The front gauze is the spare gauze. At the same time, start the electric moving ring 4 to move left and right, driving the electric rotating ring 5 to move left and right. The electric rotating ring 5 drives the gauze to move left and right through the fixed plate 6. The left and right movement of the gauze fully dresses the patient's wound. And the fixed plate 6 drives the electromagnet 13 to rotate. The rotation of the electromagnet 13 drives the mounting ring 9 to move left and right through the iron plate 10. The mounting ring 9 drives the annular plate 8 to move left and right. The annular plate 8 causes the return spring 12 to continuously expand and contract. When the patient's wound is being dressed and the rear gauze is used up, the thickness sensor 11 detects that the amount of the rear gauze is insufficient. The thickness sensor 11 controls the electromagnet 13 to turn off through the control module. The electromagnet 13 turns off and stops attracting the iron plate 10. Due to the action of the return spring 12, the annular plate 8 drives the mounting ring 9 to move left to reset. The mounting ring 9 drives the iron plate 10 and the second clamp 14 to move left to reset. The second clamp 14 resets and pulls the head end of the front spare gauze to move left. Subsequently, due to the separation of the electromagnet 13 and the iron plate 10, the rotation of the electromagnet 13 will not drive the iron plate 10 to rotate. The mounting ring 9 stops driving the end of the front spare gauze to rotate through the second clamp 14. At this time, the rotation of the electric rotating ring 5 drives the front spare gauze to rotate through the fixed plate 6 to continue dressing the patient's wound without interrupting the dressing, thus improving the dressing change efficiency. When the dressing of the patient's wound is completed, make the electric moving ring 4 drive the electric rotating ring 5 to move left to reset, turn off the electric rotating ring 5, and the fixed plate 6 stops the sand belt from rotating. The medical staff can then twist the first clamp 51 and the second clamp 14 to loosen the end of the gauze, and the patient can move the upper limb out of the housing 1. In this way, the dressing change is completed. Similarly, when the patient's lower limb needs to be dressed, follow the above operations to pass the lower limb through the housing 1 and place it on the cover plate 3 to complete the dressing.When the spare gauze is also used up, the two rolls of gauze can be placed on the fixing plate 6 again for subsequent use. And the thickness sensor 11 controls the electromagnet 13 to start through the control module, and the electromagnet 13 starts to magnetically fix the iron plate 10 again. After the patient's dressing change is completed, pull the cover plate 3 to swing upward to close it, and start the electric moving ring 4 to move left and right again. When the electric moving ring 4 moves left and right, it drives the annular nozzle 15 to move left and right. When the annular nozzle 15 moves to the right, the annular nozzle 15 drives the hose 156 to move to the right. When the hose 156 moves to the right, it drives the upper and lower guide wheels 154 to move outward. The guide wheel 154 drives the movable rod 153 to move outward, and the connecting spring 155 is compressed. When the annular nozzle 15 moves to the left, the annular nozzle 15 drives the hose 156 to move to the left, and the hose 156 is relaxed. Due to the action of the connecting spring 155, the movable rod 153 moves inward to drive the guide wheel 154 to move inward, and the guide wheel 154 moves inward to tighten the relaxed hose 156 to prevent the hose 156 from being in a relaxed state and causing knots, which affects the left and right movement of the annular nozzle 15, so as to ensure the normal movement of the annular nozzle 15. Then the disinfectant can be discharged into the hose 156. The disinfectant in the hose 156 is discharged into the annular nozzle 15. The annular nozzle 15 moves left and right to spray the disinfectant on the inner side of the housing 1, and the disinfectant disinfects the inner side of the housing 1. At the same time, start the ultraviolet disinfection lamp 152, and the ultraviolet disinfection lamp 152 further disinfects the inside of the housing 1. After the disinfection of the inside of the housing 1 is completed, turn off the ultraviolet disinfection lamp 152, stop discharging the disinfectant into the hose 156, the annular nozzle 15 stops spraying the disinfectant, and turn off the electric moving ring 4, and the annular nozzle 15 stops moving left and right. In this way, the residual bacteria in the housing 1 can be prevented from infecting the next patient, thus ensuring the safety of the patient's dressing change.

[0034] Please refer to Figure 8As shown in the figure, the surgical nursing dressing change device further includes a scraping component installed between the housing 1 and the electric moving ring 4. The scraping component includes a guide rod 16, a scraping plate 161, a compression spring 162, a magnetic rod 163, a collection box 164, and an inclined plate 166. Guide rods 16 are symmetrically and fixedly connected to the front and rear of the top of the housing 1. A scraping plate 161 is slidably connected between the guide rods 16 on the front and rear sides. The scraping plate 161 contacts the inner side of the housing 1. When the scraping plate 161 moves, the scraping plate 161 can scrape off the residual disinfectant liquid on the inner side of the housing 1. Compression springs 162 are symmetrically connected between the upper part of the left side surface of the scraping plate 161 and the inner side of the housing 1. A linear hole 165 is evenly spaced and opened at the bottom of the housing 1. A collection box 164 is fixedly connected to the outer bottom of the housing 1. A liquid outlet is arranged in the middle of the right side of the collection box 164. The collection box 164 can collect the disinfectant liquid. Two magnetic rods 163 are symmetrically and fixedly connected to the middle of the right side surface of the electric moving ring 4. The magnetic rods 163 correspond to the scraping plate 161. The magnetic rods 163 can drive the scraping plate 161 to move. Inclined plates 166 are fixedly connected to both the inner top and the inner bottom on the left side of the housing 1. The inclined plates 166 are on both sides of the electric moving ring 4. When the scraping plate 161 contacts the inclined plates 166, the inclined plates 166 can limit the scraping plate 161.

[0035] When the electric moving ring 4 drives the annular nozzle 15 to move left and right to disinfect the inside of the housing 1, the electric moving ring 4 also drives the magnetic rods 163 to move left and right. When the magnetic rods 163 move to the right and are magnetically in contact with the scraping plate 161, when the magnetic rods 163 move to the left at this time, the magnetic rods 163 drive the scraping plate 161 to move to the left, and the compression springs 162 are compressed. The scraping plate 161 moves to the left to scrape off the residual disinfectant liquid inside the housing 1. The scraped disinfectant liquid flows downward through the linear hole 165 and drops into the collection box 164. The collection box 164 discharges and collects the disinfectant liquid. When the scraping plate 161 moves to the left and contacts the inclined plates 166, the inclined plates 166 limit the scraping plate 161. The magnetic rods 163 continue to move to the left and are disengaged from the scraping plate 161. Due to the action of the compression springs 162, the scraping plate 161 moves to the right to reset. Repeating like this, the scraping plate 161 can continuously move left and right to scrape off the residual disinfectant liquid inside the housing 1. When the electric moving ring 4 is closed, the electric moving ring 4 stops driving the magnetic rods 163 to move, and the scraping plate 161 also stops moving left and right. In this way, it can prevent a large amount of residual disinfectant liquid in the housing 1 from affecting subsequent use, thus ensuring the normal use of the housing 1.

[0036] Please refer to Figure 9 As shown in the figure, the surgical nursing dressing change device further includes a soft pad 17. Soft pads 17 are fixedly connected to the sides of the left and right covers 3 that are close to each other. The soft pads 17 can protect the upper or lower limbs of the patient, so that the upper or lower limbs of the patient can be placed more comfortably.

[0037] When the cover plate 3 swings downward to open, the cover plate 3 drives the soft pad 17 to swing downward outside the housing 1. Then, when the patient passes the upper limb or lower limb through the housing 1 and places it on the cover plate 3, the upper limb or lower limb of the patient contacts the soft pad 17, and the soft pad 17 protects the upper limb or lower limb of the patient. In this way, the upper limb or lower limb of the patient can be placed more comfortably during the dressing change process, thereby improving the comfort of the dressing change.

[0038] Finally, it is necessary to note that the above content is only used to help understand the technical solution of the present invention and should not be construed as a limitation on the protection scope of the present invention; any non-essential improvements and adjustments made by those skilled in the art based on the above content of the present invention fall within the scope of protection required by the present invention.
