Description

Technical Field

[0001] The invention relates to the technical field of medical first aid, and in particular to a wound dressing capable of isolating seawater. Background Art

[0002] Seawater-isolating wound dressings are specialized medical dressings designed for use in hypertonic seawater environments. They protect wounds from seawater erosion while promoting wound healing. In naval combat, wounds are highly susceptible to seawater immersion and erosion, increasing the risk of infection. Seawater-isolating wound dressings adhere closely to wounds, reducing the risk of infection.

[0003] Generally speaking, when a person is traumatized, wound dressings need to be applied to the wound for protection and treatment. However, due to the different sizes of the wounds, the number of dressings required is also different. For small wounds, using too much dressing for treatment will result in a waste of dressings. When a large wound occurs in the later stage, there is a high risk of insufficient dressings.

[0004] In summary, how to solve the problem of excessive dressing waste caused by using too much dressing on a small wound has become a technical problem that those skilled in the art need to solve urgently. Therefore, it is necessary to provide a wound dressing that can isolate seawater. Summary of the Invention

[0005] To solve the above problems, the present invention provides a wound dressing that can isolate seawater. By twisting the handle to drive the rotating rod to rotate, the active plate and the driven plate are expanded to an area suitable for the size of the wound according to the size of the wound. The squeezing plate is used to squeeze the recovery fluid in the liquid storage bag onto the dressing layer, thereby realizing the use of the dressing according to the size of the wound of the injured person and reducing the waste of dressing.

[0006] In order to achieve the above object, the technical solution of the present invention is as follows: A wound dressing capable of isolating seawater comprises a box body with an opening at the bottom thereof and a covering assembly for covering the wound surface.

[0007] The box body is provided with a driving component for driving the covering component to rotate and a fixing component for fixing the box body.

[0008] The covering component is provided with a recovery component for recovering the wound surface.

[0009] A storage component for the moist recovery component is provided in the box.

[0010] The covering component is also provided with an extrusion component for extruding the storage component.

[0011] The covering assembly includes a rotating rod and a fixed plate. The fixed plate is fixedly connected to the box body. One end of the rotating rod is rotatably matched with the top wall of the box body. The end of the rotating rod away from the top wall of the box body is rotatably matched with the fixed plate. An active plate is fixedly connected to the rotating rod, and a number of driven plates are rotatably connected between the active plate and the fixed plate.

[0012] The active plate and the driven plate are both provided with sliding grooves, and sliding blocks are slidably fitted in the sliding grooves. The active plate and the driven plate are provided with a first connecting piece on the side close to the top wall of the box body, and a second connecting piece is provided on the side away from the top wall of the box body.

[0013] One end of the first connecting member is rotatably matched with the fixed plate, and the other end of the first connecting member is rotatably matched with the active plate.

[0014] One end of the second connecting member is rotationally matched with the driven plate adjacent to the fixed plate, and the other end of the second connecting member is rotationally matched with the sliding block in the sliding groove of the active plate.

[0015] The technical principle of this solution is as follows: The patient twists the drive assembly, driving the rotating rod within the housing. This rotation of the rotating rod drives the active plate, which is connected to the fixed plate and the sliding block in the active plate's chute via a first connector. It is also connected to the adjacent driven plate and the active plate via a second connector. When the active plate rotates, the first and second connectors act as a transmission, driving the driven plate to rotate and expand relative to the fixed plate. This allows the driven plate to flexibly cover and adjust the wound surface to suit different wound surface requirements.

[0016] The above scheme has the following beneficial effects:

[0017] 1. The present invention realizes a stable and flexible rotation structure of the covering assembly through the first connecting rod and the second connecting member, so that the wounded can adjust the coverage area of ​​the dressing according to the size of the wound, thereby saving dressing and reducing dressing waste.

[0018] 2. The present invention facilitates rapid wound recovery through the provision of a recovery component, and the storage component provides the necessary moist environment for the recovery component. The design of the extrusion component ensures that the liquid in the storage component is evenly and timely released to the recovery component, maintaining its moist state.

[0019] Furthermore, the first connecting member includes a main connecting rod and a plurality of first connecting rods, one end of the main connecting rod is rotationally engaged with the fixed plate, and the other end of the main connecting rod is rotationally engaged with the sliding block in the adjacent driven plate sliding groove.

[0020] One end of each adjacent first connecting rod is rotationally matched with the adjacent driven plate, and the other end of each adjacent first connecting rod is rotationally matched with the sliding block in the adjacent driven plate sliding groove.

[0021] The second connecting member includes a plurality of second connecting rods, one end of each adjacent second connecting rod is rotationally matched with the adjacent driven plate, and the other end of each adjacent second connecting rod is rotationally matched with the sliding block in the adjacent driven plate slot.

[0022] Beneficial Effects: The coordination of the main connecting rod, several first connecting rods, and several second connecting rods allows the driven plate to flexibly expand or contract as the active plate rotates, better adapting to the shape of the wound. This design not only improves the dressing's fit but also prevents it from falling off or shifting during rotation, providing a more stable environment for wound recovery.

[0023] Furthermore, the recovery component includes an elastic dressing cloth, and the side of the driven plate away from the top wall of the box body is fixedly connected to the dressing cloth, and a dry dressing layer is fixedly connected to the dressing cloth.

[0024] Beneficial effects: The dressing cloth in the recovery component is elastic and can fit closely to the wound surface, providing continuous compression and protection for the wound surface, thereby improving the efficacy and use value of the dressing.

[0025] Furthermore, the storage component includes a liquid storage bag, which is fixedly connected to the top wall of the box body, the rotating rod rotates in conjunction with the liquid storage bag, the liquid storage bag is provided with a liquid inlet and a liquid outlet, the liquid outlet is fixedly connected to an infusion pipe, the liquid outlet is fixedly connected to a pressure release valve, and a plurality of through holes are provided on the side of the driven plate away from the top wall of the box body, and the through holes are all connected to the infusion pipe.

[0026] Beneficial effects: The reservoir can store recovery fluid, and the design of the pressure release valve can ensure that the liquid in the reservoir is evenly released under appropriate pressure. The through hole on the driven plate is connected to the liquid outlet, allowing the liquid to directly penetrate into the dressing layer, providing continuous moistening for the wound surface.

[0027] Furthermore, the driving assembly includes a handle, which is rotatably connected to the box body, and one end of the handle close to the box body passes through the box body and is coaxially fixedly connected to the rotating rod.

[0028] Beneficial effects: The wounded can conveniently rotate the rotating rod manually to adapt to the needs of different wound surfaces. The coaxial fixed connection between the handle and the rotating rod ensures the stability and accuracy of the rotation.

[0029] Furthermore, the fixing assembly includes a plurality of fixing straps, one end of each fixing strap is fixedly connected to the box body, and the other end of each fixing strap is fixedly connected to a Velcro.

[0030] Benefits: The fixing strap and Velcro design ensures the dressing remains securely in place on the patient, preventing it from falling off or shifting during movement or activity. The Velcro facilitates adjustment and removal of the fixing strap, improving the dressing's applicability and comfort.

[0031] Furthermore, the extrusion assembly includes a plurality of extrusion rods, one end of each of the extrusion rods is fixedly connected to a sliding block rotatably matched with the first connecting rod, and the other end of each of the extrusion rods is fixedly connected to an extrusion plate.

[0032] Beneficial effects: The extrusion rod and extrusion plate design in the extrusion assembly can automatically squeeze the liquid reservoir as the sliding block slides, ensuring that the recovery fluid in the liquid reservoir can be released onto the dressing layer in a timely manner, thereby improving the automation and use efficiency of the dressing.

[0033] Furthermore, a sealing strip is fixedly connected around the dressing cloth.

[0034] Beneficial Effects: The sealing strip design further enhances the dressing's isolation function, effectively preventing the infiltration of external pollutants such as seawater. It also improves the dressing's sealing and durability, allowing it to maintain its performance over long periods of time in harsh environments.

[0035] Furthermore, a transparent window is fixedly connected to the surface of the box.

[0036] Beneficial effects: The transparent window allows the wounded to observe the condition of the wound and the status of the dressing at any time, and to promptly discover and deal with possible problems.

[0037] Furthermore, the grip is engraved with anti-slip texture.

[0038] Beneficial effect: The anti-slip texture design engraved on the grip enhances the friction and gripping feel of the grip, allowing the wounded to hold the grip more firmly for rotation operations.

[0039] Additional aspects and advantages of the present invention will be set forth in part in the description which follows and, in part, will be obvious from the description which follows, or may be learned by practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0046] The following is further described in detail through specific implementation methods:

[0047] Example 1:

[0048] As attached Figure 1-Figure 5 As shown: A wound dressing capable of isolating seawater comprises a box body 1 with an opening at the bottom thereof and a covering assembly for covering the wound surface arranged inside the box body 1.

[0049] The box body 1 is provided with a driving assembly for driving the covering assembly to rotate and a fixing assembly for fixing the box body 1 .

[0050] The covering component is provided with a recovery component for recovering the wound surface.

[0051] A storage component for the moisturizing recovery component is provided in the box body 1 .

[0052] The covering component is also provided with an extrusion component for extruding the storage component.

[0053] like Figure 2 As shown, the covering assembly includes a rotating rod 4 and a fixed plate 5, the fixed plate 5 is fixedly connected to the box body 1 with bolts, one end of the rotating rod 4 is rotatably matched with the inner top wall of the box body 1, and the end of the rotating rod 4 away from the inner top wall of the box body 1 is rotatably matched with the fixed plate 5, and an active plate 12 is fixedly connected to the rotating rod 4 with bolts, and a number of driven plates 7 are rotatably connected between the active plate 12 and the fixed plate 5.

[0054] Combine Figure 3 As shown, both the active plate 12 and the driven plate 7 are provided with sliding grooves, and sliding blocks 8 are slidably fitted in the sliding grooves. The active plate 12 and the driven plate 7 are provided with a first connecting piece on the side close to the inner top wall of the box body 1, and the active plate 12 and the driven plate 7 are provided with a second connecting piece on the side away from the inner top wall of the box body 1.

[0055] One end of the first connecting member is rotationally engaged with the fixed plate 5 , and the other end of the first connecting member is rotationally engaged with the active plate 12 .

[0056] One end of the second connecting member is rotationally engaged with the driven plate 7 adjacent to the fixed plate 5 , and the other end of the second connecting member is rotationally engaged with the sliding block 8 in the sliding groove of the active plate 12 .

[0057] The first connecting member includes a main connecting rod 6 and a plurality of first connecting rods 9. One end of the main connecting rod 6 is rotationally engaged with the fixed plate 5, and the other end of the main connecting rod 6 is rotationally engaged with the sliding block 8 in the sliding groove of the adjacent driven plate 7.

[0058] One end of each adjacent first connecting rod 9 is rotationally engaged with the adjacent driven plate 7 , and the other end of each adjacent first connecting rod 9 is rotationally engaged with the sliding block 8 in the sliding groove of the adjacent driven plate 7 .

[0059] The second connecting member includes a plurality of second connecting rods 13, one end of each adjacent second connecting rod 13 is rotationally engaged with the adjacent driven plate 7, and the other end of each adjacent second connecting rod 13 is rotationally engaged with the sliding block 8 in the slide groove of the adjacent driven plate 7.

[0060] like Figure 4 As shown, the recovery assembly includes an elastic dressing cloth 15, and the side of the driven plate 7 away from the inner top wall of the box body 1 is bonded to the dressing cloth 15, and a dry dressing layer is bonded to the dressing cloth 15.

[0061] Combine Figure 5 As shown, the storage assembly includes a liquid storage capsule 14, which is fixedly connected to the inner top wall of the box body 1 with bolts, and the rotating rod 4 rotates with the liquid storage capsule 14. A liquid inlet and a liquid outlet are opened in the liquid storage capsule 14, and the liquid outlet is fixedly connected to the infusion pipeline by screws, and the liquid outlet is fixedly connected to the pressure release valve by screws. A plurality of through holes are opened on the side of the driven plate 7 away from the inner top wall of the box body 1, and the through holes are all connected to the infusion pipeline.

[0062] The driving assembly includes a handle 2, which is rotatably connected to the box body 1. One end of the handle 2 close to the box body 1 passes through the box body 1 and is fixedly connected to the rotating rod 4 by a coaxial bolt.

[0063] The fixing assembly includes a plurality of fixing belts 3, one end of each fixing belt 3 is fixedly connected to the box body 1 by screws, and the other end of each fixing belt 3 is adhered with Velcro.

[0064] The extrusion assembly includes a plurality of extrusion rods 10 , one end of each of the extrusion rods 10 is screw-fixedly connected to a sliding block 8 rotatably matched with the first connecting rod 9 , and the other end of each of the extrusion rods 10 is screw-fixedly connected to an extrusion plate 11 .

[0065] The specific implementation process is as follows: first, after being injured, the wounded can cover the wound with the box 1 so that the opening is aligned with the wound surface. Then the wounded can tie the fixing belt 3 to the body and use Velcro to further fix the box 1.

[0066] by Figure 1 and Figure 2For example, after the box 1 is fixed, the injured person can hold the handle 2 and rotate it. When the handle 2 rotates, it will drive the rotating rod 4 to rotate. As the rotating rod 4 rotates, the rotating rod 4 will drive the active plate 12 to rotate.

[0067] Combine Figure 3 As shown, one end of the main connecting rod 6 is rotationally engaged with the fixed plate 5, while the other end of the main connecting rod 6 is rotationally engaged with the sliding block 8 in the slot of the adjacent driven plate 7. One end of each adjacent first connecting rod 9 is rotationally engaged with the adjacent driven plate 7, while the other end of each adjacent first connecting rod 9 is rotationally engaged with the sliding block 8 in the slot of the adjacent driven plate 7. One end of each adjacent second connecting rod 13 is rotationally engaged with the adjacent driven plate 7, while the other end of each adjacent second connecting rod 13 is rotationally engaged with the sliding block 8 in the slot of the adjacent driven plate 7.

[0068] Therefore, when the active plate 12 rotates, it drives the driven plate 7 to rotate via the main connecting rod 6, the first connecting rod 9, and the second connecting rod 13. As the driven plate 7 rotates, the dressing 15 unfolds accordingly. The patient can adjust the unfolding angle of the dressing 15 based on the size of their wound. A dry dressing layer is bonded to the dressing 15.

[0069] Combine Figure 4 As shown, as the dressing 15 is unfolded, the sliding block 8 will slide inward in the sliding groove. As the sliding block 8 slides, the sliding block 8 will drive the extrusion rod 10 to slide inward, and the extrusion rod 10 will drive the extrusion plate 11 to move inward.

[0070] by Figure 2 For example, when the squeezing plate 11 moves inward, the squeezing plate 11 will squeeze the liquid reservoir 14. The liquid reservoir 14 contains recovery fluid in advance. When the squeezing plate 11 squeezes the liquid reservoir 14, the pressure in the liquid reservoir 14 will increase. At this time, the recovery fluid will enter the driven plate 7 through the pressure relief valve and the infusion pipe. Then the recovery fluid can flow through the through hole to the dressing cloth 15, infiltrate the dressing layer, and restore the dressing to a therapeutic effect.

[0071] The dry dressing layer can effectively increase the storage time of the dressing and improve the preservation effect of the dressing. The outflow of the recovery liquid in the liquid storage capsule 14 is adjusted by the squeezing force of the squeezing plate 11, thereby extending the use effect of the dressing.

[0072] The wounded can adjust the unfolding angle of the dressing cloth 15 according to the size of the wound, which is helpful to reduce the waste of dressing.

[0073] Example 2:

[0074] The difference from the above embodiment is that sealing strips (not shown in the figure) are bonded around the dressing cloth 15 .

[0075] The specific implementation process is as follows: the sealing strip can fit tightly with the skin of the injured person, effectively preventing seawater or other pollutants from entering the wound, thereby keeping the wound clean, enhancing the waterproof performance of the dressing layer, and improving the protection effect of the wound in the marine environment.

[0076] Example 3:

[0077] The difference from the above embodiment is that a transparent window (not shown in the figure) is fixedly connected to the surface of the box body 1 by screws.

[0078] The specific implementation process is as follows: the transparent window is fixed on the surface of the box 1, allowing the wounded to directly observe the wound condition through the box 1, thereby improving the wounded's understanding of their own wound recovery condition.

[0079] Example 4:

[0080] like Figure 1 As shown, the difference from the above embodiment is that the handle 2 is engraved with anti-slip texture.

[0081] The specific implementation process is as follows: the anti-slip texture improves the safety of the handle 2, especially in a wet and slippery marine environment, and effectively prevents the dressing layer from being unable to be unfolded due to hand slippage.

[0082] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
