Description

Technical Field

[0001] This invention relates to the field of medical dressing fixation device technology, specifically a convenient fixation device and method for disposable dressing packs. Background Technology

[0002] In the clinical wound treatment process, dressings are key consumables for protecting wounds and promoting healing. Currently, most disposable dressings commonly used in clinical practice are directly adhered to the patient's wound surface through their own adhesive layer, and then fixed with medical tape.

[0003] However, this type of fixation method has many drawbacks: First, the patient's skin sweats and body position changes frequently during activity, which can easily lead to a decrease in the adhesiveness of the dressing, resulting in loosening and displacement. This makes it impossible to effectively cover and protect the wound, affecting the treatment effect and even potentially causing secondary contamination of the wound. Second, when the dressing is removed, its adhesive layer can easily leave adhesive residue on the skin surface. If not cleaned in time, long-term adhesion can irritate the skin, causing skin allergies, redness, and swelling. In severe cases, it may even induce skin infections around the wound. Third, the removed dressings are often discarded randomly, which not only easily causes medical waste to scatter and pollute the area but may also cause cross-infection due to wound secretions carried by the dressing. At the same time, traditional dressings lack a dedicated storage structure, making them impractical. In view of the above-mentioned shortcomings of existing technologies, there is an urgent need for a device that can solve the problems of unstable dressing fixation, adhesive residue, and inconvenient dressing storage, so as to improve the safety and convenience of wound treatment. Summary of the Invention

[0006] Preferably, the linkage assembly includes a second connecting frame disposed on one side of the two first connecting frames. The two second connecting frames are connected by a linkage rod and are located on one side of a transverse rod. A connector is provided on the transverse rod, and the other end of the connector is sleeved on the linkage rod and rotatably engaged with it. The end of the transverse rod is connected to the middle of the L-shaped frame and is located outside the first connecting frame. A mating rod is sleeved on the top of the L-shaped frame, and the other end of the mating rod is sleeved on the outer side of one of the hinged frames. The other end of the L-shaped frame is sleeved on the end of the linkage rod and rotatably engaged with it. A first crank is provided at the end of the transverse rod away from the L-shaped frame, and the side end of the first crank is connected to the side end of the adjacent first connecting frame. A second crank is provided at the end of the linkage rod away from the L-shaped frame, and the side end of the second crank is connected to the side end of the adjacent second connecting frame. An auxiliary rod is hinged to the other end of the first crank, and the other end of the auxiliary rod is hinged to the other end of the second crank. The two second connecting frames are connected by a support frame.

[0007] Preferably, the scraping assembly includes a linkage bevel gear located at the hinge point between the auxiliary rod and the second crank. A control bevel gear meshes with the side end of the linkage bevel gear. The included angle between the control bevel gear and the linkage bevel gear is 90 degrees. The center of the control bevel gear is rotatably connected to the auxiliary frame. The bottom of the auxiliary frame is connected to the top of the second connecting frame. A control disk is connected to the center of the control bevel gear. An actuating rod is eccentrically hinged to the control disk. The other end of the actuating rod is hinged to the side end of the slide plate. The slide plate is slidably disposed in the sliding groove of the support frame. The other end of the slide plate is located on one side of the actuating frame. Several protrusions are evenly distributed on the top of the other end of the slide plate.

[0008] Preferably, the actuating frame is rotatably connected to a connecting shaft via a coil spring. Both ends of the connecting shaft are connected to the center of a connecting plate. An abutment rod is eccentrically connected to the side end of the connecting plate near the protrusions, and the abutment rod is located between several protrusions. Another connecting plate is eccentrically connected to a mating crank, the other end of which is hinged to one end of a trigger rod. A fixed rod is provided on the side of the support frame away from the first connecting frame. Several scrapers are evenly distributed on the fixed rod. The middle of each scraper is rotatably connected to the fixed rod via a movable shaft. The other end of each movable shaft is hinged to one end of a synchronizing rod. The other ends of several synchronizing rods are hinged to one side of an integrated frame. The middle of the integrated frame is hinged to the middle of the trigger rod. The end of the trigger rod away from the mating crank is hinged to the movable shaft located in the middle. A cleaning plate is provided on the side of the fixed rod away from the protrusions.

[0009] Preferably, the packaging assembly includes a cap located outside the cleaning sheet. The two ends of the cap are respectively hinged to the side ends of adjacent second connecting frames via arc-shaped frames. A gravity balance bar is connected to the side end of the arc-shaped frame. An L-shaped abutment bar is provided on the top of the two first connecting frames. When the second connecting frame is combined with the first connecting frame, the end of the L-shaped abutment bar can abut against the gravity balance bar to seal the cap at the bottom of the first and second connecting frames.

[0010] Preferably, the binding assembly includes a main strap located on the outside of the fixing bracket, and a secondary strap for use with the main strap is provided on the outside of the second connecting frame away from the first connecting frame. The two sides of the secondary strap are connected to the inner side of the corresponding hinge frame through soft plastic rods. The inner side of both the main strap and the secondary strap is provided with an adhesive part, which is a medical-grade pressure-sensitive adhesive layer. The surface of the pressure-sensitive adhesive layer is covered with a release film. The release film is used to protect the adhesiveness of the pressure-sensitive adhesive layer. When in use, the release film can be removed to attach and fix the main strap and the secondary strap to the skin surface.

[0011] Preferably, the fixing bracket, the first connecting bracket, the second connecting bracket, and the support bracket are all made of medical-grade soft plastic, and the side of the fixing bracket, the first connecting bracket, the second connecting bracket, and the support bracket that is in contact with human skin is provided with an anti-slip silicone pad.

[0012] Preferably, the method of using the disposable dressing pack portable fixator includes the following steps:

[0013] S1: After treatment, by controlling the handrail to deflect to one side of the fixed support, the two first connecting frames are driven to deflect around the rotating rod as the axis. Through the cooperation of the swing rod and the telescopic rod, the deflection is achieved. During the deflection, the connecting parts on the transverse rod drive the linkage rod and the two second connecting frames to move synchronously. Through the first and second cranks, under the action of the auxiliary rod, the two second connecting frames and the support frame are deflected and moved closer to the inside of the two opened first connecting frames. Through the work of the L-shaped frame and the cooperating rod, the movement process is stabilized, thereby opening the binding device and dressing pack from one side, so that the first connecting frames and the second connecting frames are combined.

[0014] S2: During the opening process, the auxiliary rod drives the linkage bevel gear to rotate, which in turn drives the control bevel gear meshing with it to rotate, thereby driving the control panel to rotate on the auxiliary frame. Through the eccentrically set toggle rod, the toggle frame is driven to reciprocate in the sliding groove. Through the set protrusion, it can intermittently cooperate with the abutment rod, so that the abutment rod drives the trigger rod to deflect intermittently through the connecting shaft and connecting plate. When the second connecting frame moves closer to the first connecting frame, it will drive several scrapers on the fixed rod to wipe away the residual adhesive residue on the patient's skin. Through the cooperation of the trigger rod and the integrated frame, several scrapers will swing intermittently during wiping to wipe away stubborn adhesive residue, and can be collected by the cleaning plate set on the outside.

[0015] S3: When the second connecting frame and the first connecting frame deflect and come together, the L-shaped abutment rod abuts against the gravity balance bar, thereby driving the cover to cover the bottom of the first connecting frame and the second connecting frame from the outside with the arc frame as the axis.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] This invention avoids the dressing pack from becoming loose or shifting due to skin sweating or changes in body position during use, ensuring that the dressing pack always tightly covers the wound, providing a stable protective environment for wound healing, guaranteeing treatment effectiveness, and avoiding residual adhesive residue that could cause skin allergies or infections, thus improving the safety of wound treatment. Through the encapsulation component, the removed dressing pack can be directly stored in the enclosed space at the bottom of the supporting component without additional manual handling, avoiding problems such as medical waste scattering and cross-infection caused by careless dressing disposal, while also simplifying the operation process and improving the practicality of the device.

[0018] In this invention, the supporting components and linkage components can stably position the dressing pack at the wound site, ensuring the treatment effect, while avoiding skin damage caused by violent tearing and improving the convenience of use.

[0019] In this invention, the scraping component drives several scrapers to oscillate intermittently during wiping, wiping away stubborn adhesive residue. The residue can also be collected by a cleaning plate on the outside, scraping away and gathering it to one side. This avoids residual adhesive residue, which could cause skin allergies or infections, thus improving the safety of wound treatment.

[0020] In this invention, the sealing component allows the removed dressing pack to be directly stored in the closed space at the bottom without additional manual handling, avoiding problems such as medical waste scattering and cross-infection caused by the random disposal of dressings. At the same time, it simplifies the operation process and improves the practicality of the device. Attached Figure Description

[0036] Please see Figures 1 to 13 This invention provides a technical solution: a convenient fixator for disposable dressing packs, including a fixing bracket 1. The fixing bracket 1 has a support component 2 integrally formed on its side for placing the dressing pack. The support component 2 has an installation groove 3. The installation groove 3 has a binding device 4 that is matched and sealed with the disposable dressing pack. One side of the binding device 4 is fixedly connected to the edge of the dressing pack, and the other side can be directly attached to the patient's skin to achieve initial fixation of the dressing pack. The support component 2 has a linkage component 5. The side of the linkage component 5 has a scraping adhesive component 7 for cooperation. The end of the scraping adhesive component 7 has a sealing component 9 for removal. The fixing bracket 1 has binding components 10 on both sides for the patient to wear.

[0037] In this embodiment, as Figures 1 to 6 As shown, the bearing assembly 2 includes hinge frames 21 symmetrically arranged on both sides of the fixed bracket 1. A rotating rod 22 is rotatably connected between the two hinge frames 21. Two first connecting frames 23 are symmetrically arranged on both sides of the rotating rod 22. The two first connecting frames 23 are located between the two hinge frames 21. The ends of the two first connecting frames 23 away from the hinge frames 21 are connected by a transverse rod 24. The binding device 4 is located between the two first connecting frames 23. A swing rod 25 is provided on the outer side of one of the hinge frames 21. One end of the swing rod 25 is sleeved on the rotating rod 22. The other end of the swing rod 25 is hinged to the telescopic end of the telescopic rod 26. The tail of the telescopic rod 26 is rotatably connected to the side end of the fixed bracket 1. The tops of the two first connecting frames 23 on the side away from the hinge frames 21 are connected by a handrail 27.

[0038] The linkage assembly 5 includes a second connecting frame 51 disposed on one side of the two first connecting frames 23. The two second connecting frames 51 are connected by a linkage rod 52 and are located on one side of a transverse rod 24. A connector 53 is provided on the transverse rod 24. The other end of the connector 53 is sleeved on the linkage rod 52 and rotatably engaged with it. The end of the transverse rod 24 is connected to the middle of an L-shaped frame 54 and is located outside the first connecting frame 23. A mating rod 55 is sleeved on the top of the L-shaped frame 54. The other end of the mating rod 55 is sleeved on the outer side of a retaining pin 56 of one of the hinge frames 21. The other end of the frame 54 is sleeved on the end of the linkage rod 52 and rotates with it. The end of the transverse rod 24 away from the L-shaped frame 54 is provided with a first crank 57. The side end of the first crank 57 is connected to the side end of the adjacent first connecting frame 23. The end of the linkage rod 52 away from the L-shaped frame 54 is provided with a second crank 58. The side end of the second crank 58 is connected to the side end of the adjacent second connecting frame 51. The other end of the first crank 57 is hinged with an auxiliary rod 59. The other end of the auxiliary rod 59 is hinged to the other end of the second crank 58. The two second connecting frames 51 are connected by a support frame 60.

[0039] After treatment, by controlling the handrail 27 to deflect to one side of the fixed bracket 1, the two first connecting frames 23 are driven to deflect around the rotating rod 22 as the axis. Through the cooperation of the swing rod 25 and the telescopic rod 26, the deflection is achieved. During the deflection, the connecting rod 52 and the two second connecting frames 51 are driven to move synchronously through the connector 53 on the transverse rod 24. Through the first crank 57 and the second crank 58, under the action of the auxiliary rod 59, the two second connecting frames 51 and the support frame 60 are deflected and moved closer to the inside of the two opened first connecting frames 23. Through the work of the L-shaped frame 54 and the cooperating rod 55, the movement process is stabilized, and then the binding device 4 and the dressing pack are opened from one side, so that the first connecting frames 23 and the second connecting frames 51 are combined, avoiding skin damage caused by violent tearing and improving the convenience of use.

[0040] In this embodiment, as Figures 7 to 12 As shown, the scraping assembly 7 includes a linkage bevel gear 71 located at the hinge point between the auxiliary rod 59 and the second crank 58. A control bevel gear 72 meshes with the side end of the linkage bevel gear 71. The included angle between the control bevel gear 72 and the linkage bevel gear 71 is 90 degrees. The center of the control bevel gear 72 is rotatably connected to the auxiliary frame 73. The bottom of the auxiliary frame 73 is connected to the top of the second connecting frame 51. A control disk 74 is connected to the center of the control bevel gear 72. An actuating rod 75 is eccentrically hinged to the control disk 74. The other end of the actuating rod 75 is hinged to the side end of the slide plate 76. The slide plate 76 is slidably disposed in the sliding groove 77 of the support frame 60. The other end of the slide plate 76 is located on one side of the actuating frame 78. Several protrusions 79 are evenly distributed on the top of the other end of the slide plate 76.

[0041] The actuating frame 78 is rotatably connected to a connecting shaft 80 via a coil spring. Both ends of the connecting shaft 80 are connected to the center of a connecting disc 81. An abutment rod 82 is eccentrically connected to the side end of the connecting disc 81 near the protrusion 79, and the abutment rod 82 is located between several protrusions 79. Another connecting disc 81 is eccentrically connected to a mating crank 83, the other end of which is hinged to one end of a trigger rod 84. A fixing rod 85 is provided on the side of the support frame 60 away from the first connecting frame 23. The fixing rod 85... A plurality of scrapers 86 are evenly distributed. The middle part of each scraper 86 is rotatably connected to a fixed rod 85 via a movable shaft 87. The other end of each movable shaft 87 is hinged to one end of a synchronizing rod 871. The other end of the plurality of synchronizing rods 871 is hinged to one side of an integrated frame 88. The middle part of the integrated frame 88 is hinged to the middle part of a trigger rod 84. The end of the trigger rod 84 away from the cooperating crank 83 is hinged to the movable shaft 87 located in the middle. A cleaning plate 89 is provided on the side of the fixed rod 85 away from the protrusion 79.

[0042] During the opening process, the auxiliary rod 59 drives the linkage bevel gear 71 to rotate, which in turn drives the control bevel gear 72 to rotate, thereby causing the control disk 74 to rotate on the auxiliary frame 73. The eccentrically set toggle rod 75 drives the toggle frame 78 to reciprocate within the sliding groove 77. The protrusion 79 intermittently engages with the abutment rod 82, causing the abutment rod 82 to intermittently deflect the trigger rod 84 via the connecting shaft 80 and the connecting disk 81. When the second connecting frame 51 moves closer to the first connecting frame 23, it drives several scrapers 86 on the fixed rod 85 to wipe away residual adhesive residue on the patient's skin. Through the cooperation of the trigger rod 84 and the integrated frame 88, the scrapers 86 intermittently swing during wiping, wiping away stubborn adhesive residue. The residue can be collected by the cleaning plate 89 set on the outside, scraping away and gathering it to one side, thus avoiding residual adhesive residue and the risk of skin allergies or infections, improving the safety of wound treatment.

[0043] In this embodiment, as Figure 13 As shown, the encapsulation assembly 9 includes a cover 91 located outside the cleaning sheet 89. The two ends of the cover 91 are respectively hinged to the side ends of the adjacent second connecting frame 51 via an arc-shaped frame 92. A gravity balance bar 93 is connected to the side end of the arc-shaped frame 92. An L-shaped abutment bar 94 is provided on the top of the two first connecting frames 23. When the second connecting frame 51 and the first connecting frame 23 are combined, the end of the L-shaped abutment bar 94 can abut against the gravity balance bar 93 to seal the cover 91 at the bottom of the first connecting frame 23 and the second connecting frame 51.

[0044] When the second connecting frame 51 and the first connecting frame 23 are deflected and assembled, the L-shaped abutment rod 94 abuts against the gravity balance rod 93, thereby causing the cover 91 to cover the bottom of the first connecting frame 23 and the second connecting frame 51 from the outside with the arc frame 92 as the axis. This allows the removed dressing pack to be directly stored in the closed space at the bottom without additional manual handling, avoiding problems such as medical waste scattering and cross-infection caused by the random disposal of dressings. At the same time, it simplifies the operation process and improves the practicality of the device.

[0045] In this embodiment, as Figure 1As shown, the binding assembly 10 includes a main strap 101 located outside the fixing bracket 1. The second connecting frame 51 is provided with a secondary strap 102 on the outer side away from the first connecting frame 23, which is used in conjunction with the main strap 101. The two sides of the secondary strap 102 are connected to the inner side of the corresponding hinge frame 21 through soft plastic rods 103. The inner side of both the main strap 101 and the secondary strap 102 is provided with a bonding part 104. The bonding part 104 is a medical-grade pressure-sensitive adhesive layer. The surface of the pressure-sensitive adhesive layer is covered with a release film. The release film is used to protect the adhesiveness of the pressure-sensitive adhesive layer. When in use, the release film can be removed to bond and fix the main strap 101 and the secondary strap 102 to the skin surface.

[0046] By setting a main strap 101 with a fitting part 104 and a secondary strap 102, the injured person can choose to attach or bind the strap to the injured person's body according to the actual situation. The soft plastic rod 103 can adapt to the curvature change, which can not only ensure the fixation is stable, but also avoid skin damage and residual adhesive residue when removing it.

[0047] In this embodiment, as Figures 1 to 7 As shown, the fixed bracket 1, the first connecting bracket 23, the second connecting bracket 51, and the support bracket 60 are all made of medical-grade soft plastic. The fixed bracket 1, the first connecting bracket 23, the second connecting bracket 51, and the support bracket 60 are all provided with anti-slip silicone pads on the side that contacts the human skin. The anti-slip silicone pads can prevent the bracket from sliding when worn, and the medical-grade soft plastic can improve the wearing comfort.

[0048] In this embodiment, as Figures 1 to 13 As shown, a method for using a disposable dressing pack fixator includes the following steps:

[0049] S1: After treatment, by controlling the handrail 27 to deflect to one side of the fixed bracket 1, the two first connecting frames 23 are driven to deflect around the rotating rod 22 as the axis. Through the cooperation of the swing rod 25 and the telescopic rod 26, the deflection is achieved. During the deflection, the connecting rod 52 and the two second connecting frames 51 are driven to move synchronously through the connector 53 on the transverse rod 24. Through the first crank 57 and the second crank 58, under the action of the auxiliary rod 59, the two second connecting frames 51 and the support frame 60 are deflected and moved closer to the inside of the two opened first connecting frames 23. Through the work of the L-shaped frame 54 and the cooperating rod 55, the movement process is stabilized, and then the binding device 4 and the dressing pack are opened from one side, so that the first connecting frame 23 and the second connecting frame 51 are combined.

[0050] S2: During the opening process, the auxiliary rod 59 drives the linkage bevel gear 71 to rotate, which in turn drives the control bevel gear 72 to rotate, thereby driving the control disk 74 to rotate on the auxiliary frame 73. The eccentrically set toggle rod 75 drives the toggle frame 78 to reciprocate within the sliding groove 77. The protrusion 79 can then intermittently cooperate with the abutment rod 82, causing the abutment rod 82 to drive the trigger rod 84 to deflect intermittently through the connecting shaft 80 and the connecting disk 81. When the second connecting frame 51 moves closer to the first connecting frame 23, it will drive several scrapers 86 on the fixed rod 85 to wipe away the residual adhesive residue on the patient's skin. Through the cooperation of the trigger rod 84 and the integrated frame 88, several scrapers 86 will swing intermittently during wiping to wipe away stubborn adhesive residue, which can be collected by the cleaning plate 89 set on the outside.

[0051] S3: When the second connecting frame 51 and the first connecting frame 23 deflect and combine with each other, the L-shaped abutment rod 94 abuts against the gravity balance rod 93, thereby driving the cover 91 to cover the bottom of the first connecting frame 23 and the second connecting frame 51 from the outside with the arc frame 92 as the axis.
