Description

Technical Field

[0001] This invention belongs to the field of medical device technology, and specifically relates to a temperature- and humidity-controlled, infection-preventing nursing dressing for spinal trauma that is adapted to extreme environments. Background Technology

[0002] Nursing dressings are classified as Class III medical devices. Their main function is to cover wounds, absorb exudate, promote healing, and prevent infection. Their core functions include protecting wounds, maintaining a moist environment, relieving pain, and reducing scar formation.

[0003] Spinal trauma is a common and high-risk type of injury in clinical practice. When spinal trauma occurs in extreme environments such as deserts, islands, jungles, and plateaus, there is often a lack of professional medical equipment and nursing conditions. The injured person often needs to perform self-rescue alone to avoid rapid deterioration of the spinal trauma site. However, spinal trauma is mostly located on the back of the injured person, which has blind spots and makes it difficult for a single person to accurately apply dressings.

[0004] While existing nursing dressings possess basic functions such as wound protection, exudate absorption, and infection prevention, they suffer from several drawbacks. They are difficult to fit tightly to the curvature of the spine, are prone to insecure fixation and displacement, and cannot be accurately applied and fixed by a single injured person to complete the back spinal injury independently. This severely affects self-rescue efficiency. Furthermore, after application, it is inconvenient to apply pressure to the back spinal injury site to stop bleeding. Even if pressure can be applied, it is easy to apply too much or too little pressure, leading to pressure injury at the spinal injury site or difficulty in effectively stopping bleeding.

[0005] To address the aforementioned issues, designing a temperature- and humidity-controlled, infection-preventing nursing dressing for spinal trauma that is suitable for extreme environments has become a problem we need to solve. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a temperature- and humidity-controlled, infection-preventing nursing dressing for spinal trauma that is adapted to extreme environments.

[0007] To achieve the above objectives, the present invention provides a temperature- and humidity-controlled, infection-preventing nursing dressing for spinal trauma adapted to extreme environments, comprising a dressing layer and an application component; The dressing layer includes a first sealing sheet and a temperature control layer, and a first adhesion layer, a contact layer, an antibacterial layer and an adsorption layer are sequentially disposed between the first sealing sheet and the temperature control layer; The patch assembly is used to assist a single user in applying the patch to the spinal injury site, and the patch assembly is connected to the temperature control layer of the dressing layer; The patch assembly includes a second sealing sheet, a second adhesive layer, a pressure airbag, a connecting sheet, a connecting strip, and an elastic strip.

[0018] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] like Figures 1 to 6 The illustration shows a temperature- and humidity-controlled, infection-preventing nursing dressing for spinal trauma adapted to extreme environments, comprising a dressing layer and an adhesive component; The dressing layer includes a first sealing sheet 1 and a temperature control layer 6. A first adhesion layer 2, a contact layer 3, an antibacterial layer 4 and an adsorption layer 5 are sequentially disposed between the first sealing sheet 1 and the temperature control layer 6. It should be noted that contact layer 3 is made of silicone material to ensure that it does not stick to the wound when in contact with spinal trauma and to keep the wound in a moist environment; It should be noted that the antibacterial layer 4 contains silver ions, povidone-iodine, and chitosan, which are used to inhibit bacterial growth and prevent wound infection. It should be noted that the absorbent layer 5 is a hydrocolloid material that absorbs the exudate produced by spinal trauma, prevents backflow, keeps the wound dry, and provides a recovery environment for the spinal wound. It should be noted that the temperature control layer 6 is made of phase change microcapsule material, which can absorb and store latent heat when heated and release the stored heat when cooled, so as to achieve the effect of temperature control on the spinal injury site. The patch assembly is used to assist a single user in applying the patch to the spinal injury site. The patch assembly is connected to the temperature control layer 6 of the dressing layer. The dressing assembly includes a second sealing sheet 7, a second adhesive layer 8, a pressure airbag 9, a connecting piece 10, a connecting strip 11, and an elastic strip 12.

[0020] The second sealing sheet 7 is disposed on the side of the temperature control layer 6 away from the first sealing sheet 1. The second adhesive layer 8 is disposed on the side of the second sealing sheet 7 away from the temperature control layer 6. The second adhesive layer 8 is fixedly installed on the side of the pressurized airbag 9. The pressurized airbag 9 is fixedly installed inside the connecting piece 10. Multiple connecting strips 11 and elastic strips 12 are provided. Multiple connecting strips 11 are fixedly installed on the outer wall of the connecting piece 10. Multiple elastic strips 12 are fixedly installed inside the connecting strips 11. One end of the elastic strip 12 is fixedly installed on the outer wall of the connecting piece 10. A third adhesive layer 13 is provided on the outer wall of the multiple connecting strips 11 away from the connecting piece 10. A third sealing sheet 14 is provided on the side of the third adhesive layer 13 away from the corresponding connecting strip 11. It should be noted that when a user applies the dressing to a wound on the spine of the back, firstly, the second sealing sheet 7 is peeled off from the temperature-controlling layer 6 and then adhered to the temperature-controlling layer 6. Next, the first sealing sheet 1 is peeled off from the first adhesive layer 2, stopping the first sealing sheet 1 from sealing the first adhesive layer 2 and the contact layer 3. At this point, the user can hold the connecting strap 11 and move the dressing layer to the back position via the connecting piece 10 and the pressure airbag 9. The elastic strip 12 on the connecting strap 11 is deformed, allowing the first adhesive layer 2 to contact the back first. This prevents the dressing layer from contacting the user's back during positioning, avoiding the contact layer 3 from adhering to bacteria from other parts of the user's back. The user can then adjust the position of the dressing layer on the back using the connecting strap 11, adjusting the connecting piece 10 and the pressure airbag 9 until the dressing layer completely covers the wound on the spine. At this point, the third sealing sheet 14 on the outer wall of the third adhesive layer 13 on the connecting strap 11 can be peeled off, and the connecting strap 11 can be pulled (first pull the two connecting straps 11 on the opposite side of the connecting piece 10, then pull the two connecting straps 11 on the same side of the connecting piece 10), so that the connecting strap 11 pulls the elastic strip 12 to deform and straighten, so that the elastic strip 12 stops obstructing the first adhesive layer 2 from contacting the back, allowing the first adhesive layer 2 to adhere to the area around the spinal injury, so that the dressing layer covers the spinal injury and prevents the wound from being exposed. After the elastic strip 12 is straightened, the user can use the third adhesive layer 13 to stick the connecting strap 11 to the front of the body, so as to help the user accurately locate and cover the spinal injury that cannot be seen on the back. This allows the user to align the dressing layer with the spinal injury before applying it, avoiding the situation where the dressing layer is misplaced and needs to be removed and repositioned.

[0021] One end of one of the connecting straps 11 is fixedly connected to a connecting box 16. An air tube 15 is fixedly installed on the outer wall of the pressurized airbag 9. The end of the air tube 15 away from the pressurized airbag 9 passes through the connecting piece 10 and the connecting strap 11 and is inserted into the inside of the connecting box 16. The end of the air tube 15 away from the pressurized airbag 9 is fixedly installed on the outer wall of a connector 17. The connector 17 is located inside the connecting box 16. A duckbill valve 18 is fixedly installed inside the connector 17. An inflatable airbag 19 is fixedly connected to the outer wall of the connector 17. The inflatable airbag 19 is connected to the duckbill valve 18. A support is fixedly installed on the top of the inflatable airbag 19. A connecting sleeve 21 is inserted into the support plate 20, the inflatable airbag 19, and the support plate 20. A pressure plate 22 is fixedly connected to the top of the connecting sleeve 21. The support plate 20 and the pressure plate 22 are slidably connected inside the connecting box 16. An air groove 23 is provided at the connection between the connecting sleeve 21 and the pressure plate 22. An air hole 24 is provided inside the pressure plate 22. A return spring 25 is fixedly installed on the side of the pressure plate 22 near the connecting sleeve 21. The return spring 25 is inserted into the connecting sleeve 21. A support block 26 is fixedly installed on the end of the return spring 25 away from the pressure plate 22. The support block 26 abuts against the inner wall of the inflatable airbag 19. It should be noted that after the dressing layer is applied, the user can press the pressure plate 22, which will move the connecting sleeve 21 and compress the return spring 25 to contract. This will cause the pressure plate 22 to slide along the inside of the connecting box 16 and abut against the support plate 20. After the pressure plate 22 abuts against the support plate 20, the air hole 24 will be sealed by the support plate 20, and the gas cannot flow. At this time, as the pressure plate 22 continues to move, the pressure plate 22 will start to compress the inflatable airbag 19 through the support plate 20 to contract, allowing the gas inside the inflatable airbag 19 to be discharged into the interior of the connector 17 through the duckbill valve 18. Subsequently, the connector 17 will discharge the gas into the interior of the pressure airbag 9 through the air tube 15, causing the pressure airbag 9 to expand and push the dressing layer to conform to the curved surface of the spinal injury, ensuring the fit between the dressing layer and the spinal injury. Furthermore, after the user stops pressing the pressure plate 22, the return spring 25 will push the pressure plate 22 to return to its original position, so that the pressure plate 22 stops adhering to the support plate 20. At this time, the air hole 24 and the air groove 23 are connected through the gap between the pressure plate 22 and the support plate 20. As the pressure plate 22 continues to return to its original position, the pressure plate 22 begins to pull the support plate 20 to return to its original position through the connecting sleeve 21, so that the support plate 20 drives the inflatable airbag 19 to unfold, allowing external gas to be discharged into the interior of the inflatable airbag 19 through the air hole 24, the gap between the pressure plate 22 and the support plate 20 and the air groove 23, so that the inflatable airbag 19 is re-inflated. Then the user can repeat the above steps until the dressing layer is completely adhered to the spinal wound.

[0022] A connecting tube 27 is fixedly connected to the outer wall of the trachea 15. The connecting tube 27 is fixedly installed inside the connecting box 16. A sealing bead 28 and a sealing spring 29 are provided inside the connecting tube 27. The sealing spring 29 abuts against the outer wall of the sealing bead 28. A threaded rod 30 is provided at the end of the sealing spring 29 away from the sealing bead 28. The threaded rod 30 is threadedly connected to the inside of the connecting tube 27. A knob 31 is fixedly connected to the end of the threaded rod 30 away from the sealing bead 28. An indicator 32 is rotatably connected to the connection part between the threaded rod 30 and the knob 31. The indicator 32 is slidably connected to the outer wall of the connecting box 16. A scale 33 is provided on the outer wall of the connecting box 16. It should be noted that when inflating the pressure airbag 9, the operator can rotate knob 31, causing knob 31 to drive threaded rod 30 to move spirally inside connecting tube 27, changing the compression pressure on sealing spring 29. This causes sealing spring 29 to change the compression pressure on sealing bead 28. The movement of threaded rod 30 will cause indicator 32 to slide along connecting box 16, changing the position of indicator 32 on scale 33. Scale 33 and indicator 32 will then coordinate to display the pressure of sealing spring 29 on sealing bead 28, allowing the user to adjust according to the spinal injury. After adjusting the pressure of sealing spring 29 on sealing bead 28, the pressure plate 22 can be pressed to inflate the pressure airbag 9. At this time, the pressure airbag 9 begins to expand, causing the dressing layer to pressurize the spinal injury until the pressure of the pressure airbag 9 on the spinal injury through the dressing layer exceeds the pressure of sealing spring 29 on sealing bead 28. Subsequently, the sealing bead 28, driven by the gas, compresses and contracts the sealing spring 29, stopping the seal on the connecting tube 27. This allows the gas inside the pressurized airbag 9 to escape through the hole between the connecting tube 27, the threaded rod 30, and the knob 31, thereby adjusting and precisely applying pressure to the spinal injury. When the spinal injury is bleeding, the pressure can be increased to stop the bleeding. When the bleeding stops, the pressure can be reduced to avoid obstructing blood circulation or causing pressure injury. At the same time, the pressure of the sealing bead 28 applied by rotating the sealing spring 29 is converted into visible data on the indicator 32 and scale 33, allowing the user to easily know the pressure applied to the spinal injury. This avoids the user manually applying pressure, which could result in excessive or insufficient pressure, and prevents situations where it is inconvenient for a single user to apply pressure to the spinal injury on their back.

[0023] Working principle: When applying a dressing to a spinal injury on the back by a single person, first connect the dressing to the application component. Then, use the application component to precisely position and apply the dressing to the wound. Subsequently, the application component can be used to adjust the pressure of the dressing on the spinal injury and apply pressure to ensure that the dressing adheres to the curved surface of the spinal injury site and applies pressure to ensure that the spinal injury is compressed and hemostasis is achieved. After the spinal injury has stopped bleeding, the pressure on the spinal injury can be reduced to avoid pressure injury. This allows the user to easily apply a dressing to a spinal injury on the back for self-rescue.
