[0018] like Figures 1 to 8 As shown, this invention relates to a dermatological wound care device, comprising a wound fixation ring 1, which consists of a rigid fixing arc 101 and a flexible fixing arc 102. The rigid fixing arc 101 is made of a rigid material, and the flexible fixing arc 102 is made of a flexible material. Since different areas of skin have different curvatures, the combination of rigid and flexible materials allows it to adapt to different skin wounds. An adhesive is bonded to the bottom of the rigid fixing arc 101 and the flexible fixing arc 102, fixing the adhesive to the outer periphery of the wound skin. An expansion bladder 2 is located at the top of the wound fixation ring 1. The expansion bladder 2 is a hollow bladder, and a device for injection is connected to the expansion bladder 2. The injection port 16 for the liquid inlet has a one-way flow-limiting valve inside. When injecting liquid, it can be injected through a syringe without a needle. The expansion bladder 2 is also equipped with a ventilation pipe 17 for heat dissipation and ventilation. The ventilation pipe 17 has a filter screen inside to filter dust and other impurities. Two limiting arcs 3 are installed on the top of the fixed hard arc 101 to constrain the edge of the expansion bladder 2. The limiting arcs 3 have a constraining effect on the bottom edge of the expansion bladder 2. One side of the limiting arc 3 is connected to an arc support 4, which supports the expansion bladder 2. The expansion bladder 2 is filled with gypsum powder 5, which mixes with the liquid and hardens quickly.
[0019] To achieve automated dressing, the expansion bladder 2 is equipped with a dressing port 6 that connects to the inside of the wound fixation ring 1. The dressing port 6 is used to input hydrogel dressings; alginate dressings can also be selected depending on the situation. Hydrogel dressings keep the wound moist and promote the dissolution of necrotic tissue, making them suitable for wounds with necrotic tissue. Alginate dressings have strong absorbency and can form a gel on the wound surface, protecting it and promoting healing; they are commonly used for wounds with significant exudation. A fixation seat 19 is located in the central area inside the expansion bladder 2, serving as an auxiliary centering point. The center of the fixation seat 19 is hollow. A connecting tube 7 is located at the center of the bottom of the expansion bladder 2, connecting to the center of the fixation seat 19. A rotating shell 8 is rotatably connected to the bottom end of the connecting tube 7. Multiple air outlet pipes 9 are connected to the bottom end of the rotating shell 8, and these pipes are curved to prevent gas from entering the central area. The hydrogel dressing is dispersed to the outer periphery. The outer periphery of the rotating shell 8 is connected to an annular shell 10. The top of the annular shell 10 is open. Multiple rotating rod structures 11 are connected to the outer periphery of the annular shell 10. The rotating rod structure 11 includes multiple cylindrical sleeves 111. Latex sleeves 112 are connected between the multiple cylindrical sleeves 111. Since the latex sleeves 112 are made of flexible material, they can fall naturally and have a certain bending ability, ensuring that they can contact the wound area on different curved surfaces. A dressing air guiding structure 12 is set between the interior of the rotating shell 8 and the interior of the connecting tube 7. The dressing air guiding structure 12 includes a first air guiding tube 121. The other end of the first air guiding tube 121 is directed to the central area of the rotating shell 8. A propeller 122 is set below the first air guiding tube 121. The outer periphery of the propeller 122 is fixed to the inner wall of the rotating shell 8. When high-speed gas passes through, it will blow the propeller 122 to rotate.
[0020] To achieve automatic tapping massage and assist wound healing, a touch-guided air structure 13 is provided between the interior of the rotating shell 8 and the interior of the connecting tube 7. The touch-guided air structure 13 includes a ring cover 131, which slides in a ring-shaped trajectory with the ring shell 10. The ring cover 131 is connected to a second air guide tube 132. A massage structure 18 is also provided on the rotating rod structure 11. The massage structure 18 includes an outer shell 181 located on the outer periphery of the cylindrical sleeve 111. The outer shell 181 is rotatably connected to the cylindrical sleeve 111. A massage mechanism is installed on the outer periphery of the outer shell 181. The press contact 182 has a rounded end with a cold air vent 183. The massage structure 18 also includes an airflow track 184 on the cylindrical sleeve 111. The airflow track 184 is a spiral structure that guides airflow. The two ends of the airflow track 184 connect the inside of the cylindrical sleeve 111 and the inside of the outer shell 181. Multiple baffles 185 are installed inside the outer shell 181. The airflow track 184 can guide the gas to blow towards the baffles 185, further driving the outer shell 181 to rotate.
[0021] To enable actuation, a three-way valve 14 and an air pump 15 are installed at the end between the dressing air-conducting structure 12 and the touch air-conducting structure 13. The three-way valve 14 connects the air outlet of the air pump 15, the first air-conducting tube 121, and the second air-conducting tube 132. The air pump 15 is a miniature air pump, which is existing technology. A miniature air pump of model PYP528-XA can be used. Through the control of the three-way valve 14, the air pump 15 can be connected to the first air-conducting tube 121 and the second air-conducting tube 132 individually, or simultaneously. The air pump 15 is powered by a mobile power supply (preferably a small button battery), which can be installed on the inflation bladder 2.
[0022] The air pump 15 and the three-way valve 14 are connected in a movable manner, allowing them to be reused and reducing waste.
[0023] Working principle: This embodiment provides a dermatological wound care device. A syringe is used to inject the liquid into the expansion bladder 2 through the injection port 16, and then shake it to mix it evenly. When it is almost set, it is bonded to the outer periphery of the wound with an adhesive. After the settling is completed, the wound can be protected. When dressing is needed, hydrogel dressing is input through dressing port 6. The air pump 15 is controlled by an external control structure to input high-speed gas into the first air guide tube 121. When the gas passes through the rotating shell 8 and the propeller 122, it can drive the rotating shell 8 to rotate, causing the ring shell 10 and the multiple cylindrical sleeves 111 and latex sleeves 112 forming the rod to rotate. Since the latex sleeve 112 is made of flexible material, it can fall naturally and has a certain bending ability, ensuring that it can contact the wound part on different curved surfaces. Combined with the staggered connection of the cylindrical sleeves 111, and the fact that the length of the latex sleeve 112 is less than that of the cylindrical sleeve 111, it is not too soft and can rotate, driving it to spread the hydrogel dressing. When massage is needed, the three-way valve 14 is adjusted, and the control structure controls the air pump 15, which simultaneously inputs high-speed gas into the first air guide tube 121 and the second air guide tube 132. While driving the rotating shell 8 to rotate, the gas enters the interior of multiple cylindrical sleeves 111. The airflow track 184 guides the gas, causing it to blow the air baffle 185, further rotating the outer shell 181 and causing the massage head 182 to rotate, performing tapping massage on the skin. Combined with the high-pressure gas sprayed from the cold air outlet 183, the cold air can be blown onto the wound, providing a cold compress effect and reducing pain.

Those skilled in the art can easily understand the spirit of this invention based on the above embodiments and make different extensions and variations, but as long as they do not depart from the spirit of this invention, they are all within the protection scope of this invention.
