Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical devices, in particular to a sterile operation platform device for burn wound dressing change. BACKGROUND

[0002] Burn is a kind of tissue damage caused by high temperature, electric current, strong radiation or corrosive substances, which can seriously damage muscles, bones, joints and even internal organs. Thermal burns are the most common, caused by direct contact with high-temperature substances. Direct flame burns the skin and mucosa. Scalds caused by hot water, hot soup, hot oil or steam. Contact injury caused by hot metal (molten steel, steel ingot) and high-temperature asphalt.

[0003] In the burn ward, patients with severe burns need to change dressings on their affected areas every day, and even several times a day in the early stage. Each time the burn patient is dressed, a large amount of normal saline is used to flush the pus water on the affected area of the patient, and then debridement is performed, followed by the application of nanometer silver ointment, the application of plaster, the wrapping with gauze. However, during the operation, a large amount of normal saline, iodine, povidone-iodine solution, hydrogen peroxide solution, potassium permanganate solution, benzalkonium bromide solution, sulfadiazine silver cream and other related drugs are splashed on the operation platform at various positions. After treating the patient, the liquid drugs, bandages, dressings and necrotic tissues are scattered, making the cleaning difficult and increasing the risk of infection for the next patient. If the next patient is not completely disinfected before the dressing change operation, it may cause the wound infection of the next patient to worsen, leading to serious complications such as sepsis and sepsis, prolonging the hospital stay and increasing the mortality rate.

[0017] Beneficial effects

[0018] The present invention has the following beneficial effects:

[0019] (1) The sterile operating platform device for changing dressings of burn wounds uses rubber support blocks and elastic bandages for soft bacterial support, quick and stable replacement of elastic bandage padding, convenient quick cleaning of liquid medicines and ultraviolet disinfection, so that cross-infection will not occur when changing dressings for each burn patient. During the dressing change process, the elastic bandage padding can be easily replaced to ensure the hygiene and suitability of the bandage, and the inside of the support platform can be thoroughly disinfected. It constructs a dual protection from both the operation process and environmental cleanliness aspects, effectively blocking the route of cross-infection, providing patients with a safe dressing change environment, avoiding cross-infection between different patients due to dressing change operation and environmental factors, and ensuring that each dressing change is carried out in an infection-free environment.

[0020] (2) The sterile operating platform device for changing dressings of burn wounds limits and fixes the elastic bandage roll, so that the burn patient's arm can be placed on the elastic bandage. The elastic bandage is supported by rubber support blocks and support platforms. Because the arm of the burn patient is often irregularly bent due to swelling or scar contracture, the soft silicone material of the rubber support block can be slightly deformed according to the shape of the arm, filling the gap between the elastic bandage and the skin. This avoids the traditional rigid support platform from being "suspended" and causing the bandage to compress the edge of the wound, causing blisters or friction injuries. When the doctor changes the dressing, the exudate, bloodstains or sloughed necrotic tissue and the sprayed saline, iodine, povidone-iodine solution, hydrogen peroxide solution, potassium permanganate solution, benzalkonium bromide solution, silver sulfadiazine cream and other related medicines are intercepted by the support platform to prevent them from flowing to the ground, reducing the route of cross-infection, and facilitating quick cleaning.

[0021] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0039] Please see Figures 1-11 The present invention provides a technical solution: a sterile operating platform device for changing dressings of burn wounds, including a burn operating platform frame 1, a lifting component 101 is provided inside the burn operating platform frame 1, and a support platform 2 is installed on the outer surface of the lifting component 101. The support platform 2 includes a cleaning component 201, a sealing and sterilization component 3, and a padding and sterilization component 4.

[0040] The bedding material sterilization component 4 includes a bedding material roller frame 401 and a threaded head cover 402. The bedding material roller frame 401 is installed on the outer surface of the sealing and sterilization component 3. The threaded head cover 402 is movably installed on the outer surface of the bedding material roller frame 401. Two movable grooves 403 are opened on the outer surface of the sealing and sterilization component 3. Fixed columns 405 are installed on the inner walls of the two movable grooves 403. Springs 406 are installed on the inner walls of the two fixed columns 405. Movable columns 407 are installed on the top surfaces of the two springs 406. A support rod 404 is installed on the outer surface of the two movable columns 407. A cutter 408 is installed on the bottom surface of the support rod 404.

[0041] The cleaning component 201 facilitates the collection of fluids used for dressing changes on burn wounds, preventing spillage. The sealing and sterilization component 3 facilitates the disinfection and sterilization of the support platform 2. The padding and sterilization component 4 facilitates quick replacement of elastic bandages, and the elastic bandage roll prevents direct contact between the patient's burned skin and the support platform 2. The padding and sterilization component 4 also includes two fixing posts 410 and two springs 411. Two limiting cavities 415 are provided on the outside of the support platform 2. The two fixing posts 410 are installed on the inner surface of the limiting cavities 415. Springs 411 are installed inside each of the two fixing posts 410.

The inner wall of the nail groove 414 is in contact with the outer surface of the fixing nail 413. Through the rubber support block 202 and the elastic bandage soft antibacterial support, the elastic bandage padding can be quickly and stably replaced, and liquid medicines can be quickly cleaned and disinfected with ultraviolet light. This ensures that cross-infection will not occur when changing dressings for each burn patient. During the dressing change process for burn patients, the elastic bandage padding can be easily replaced, ensuring the hygiene and fit of the bandage. At the same time, the inside of the support platform 2 can be thoroughly disinfected. A dual protection is constructed from both the operation process and environmental cleanliness aspects, effectively blocking the route of cross-infection, providing patients with a safe dressing change environment, avoiding cross-infection between different patients due to dressing change operation and environmental factors, and ensuring that each dressing change is carried out in an infection-free environment.

[0042] The lifting assembly 101 includes a lifting cavity 102 and a lifting column 103. The lifting cavity 102 is provided inside the burn operating platform frame 1. The lifting column 103 is movably installed on the inner wall of the lifting cavity 102. A threaded screw 104 is movably installed inside the burn operating platform frame 1. One end surface of the threaded screw 104 is in contact with the outer surface of the lifting column 103. A storage box 105 is movably installed on the outer surface of the burn operating platform frame 1. The lifting column 103 can be raised or lowered within the lifting cavity 102, thereby changing the height of the support platform 2 to accommodate different patients. The storage box 105 is convenient for placing medical instruments used for burn dressing changes.

[0043] The cleaning component 201 includes a liquid storage tank 207 and a rubber support block 202. The liquid storage tank 207 is located inside the support platform 2. The rubber support block 202 is installed on the inner wall of the liquid storage tank 207. The support platform 2 has two flow guide surfaces 203 and two flow guide surfaces 204. The support platform 2 has four flow guide channels 205. A water pipe 206 is installed on the outer surface of the support platform 2. Through the combination of the flow guide surfaces 203, 204, and flow guide channels 205, the flushed wastewater is quickly guided to the bottom of the liquid storage tank 207 for discharge, avoiding wastewater retention or backflow and keeping the operating area clean.

[0044] The sealing and sterilization assembly 3 includes a worm gear 301 and a shielding cover 305. The worm gear 301 is movably installed inside the support platform 2. Connecting plates 307 are evenly distributed on the outer surface of the worm gear 301. A shielding cover 305 is mounted on the outer surface of several connecting plates 307. An ultraviolet lamp 306 is installed inside the shielding cover 305. A rotating column 302 is movably installed inside the support platform 2. A worm wheel 303 is mounted on the outer surface of the rotating column 302. The outer surface of the worm wheel 303 meshes with the outer surface of the worm gear 301. A handle 304 is mounted on the outer surface of the shielding cover 305. The device has two slots 308 inside, and a retaining ring 309 is movably installed on the inner wall of each slot 308. One of the retaining rings 309 has an inlet slot 310 inside. The ultraviolet lamp 306 is powered by the controller. The two retaining rings 309 block the space between the support platform 2 and the shielding cover 305, thereby disinfecting and sterilizing the support platform 2 with ultraviolet light, forming an independent disinfection space, preventing ultraviolet light leakage, ensuring the safety of operators, and efficiently sterilizing the surface of the support platform 2 and the internal air, reducing the risk of cross-infection. It also disinfects and sterilizes the elastic bandage roll of the padding roller frame 401 inside.

[0045] The specific workflow of this invention is as follows: When changing dressings for a patient with an arm burn, water is slowly supplied to the water pipe 206. The water pipe 206 has evenly distributed flow holes, allowing water to flow comprehensively into the storage tank 207 from multiple directions. The water is then guided and cleaned by the first guide surface 203, the second guide surface 204, and the guide channel 205. The combination of these components quickly guides the flushed wastewater to the bottom of the storage tank 207 for discharge, preventing wastewater retention or backflow and maintaining a clean operating area. Finally, the controller controls the ultraviolet lamp 306 to connect... The system includes two retaining rings 309 that shield the support platform 2 and the cover 305, thereby disinfecting the support platform 2 with ultraviolet light, forming an independent disinfection space to prevent ultraviolet light leakage, ensuring the safety of operators, and efficiently sterilizing the surface and internal air of the support platform 2 to reduce the risk of cross-infection. It also disinfects the elastic bandage roll of the padding roller frame 401 inside. The lifting column 103 is raised and lowered in the lifting cavity 102 to change the height of the support platform 2 to accommodate different patients. The storage box 105 is convenient for storing medical devices used for burn dressing.

[0046] The two retaining rings 309 are removed from their corresponding slots 308. One of the retaining rings 309 has an inlet groove 310, which allows it to be unobstructed by the water pipe 206. The handle 304 drives the cover 305 to rotate. The cover 305 drives the worm gear 301 to rotate via the connecting plate 307. The worm gear 301 drives the worm wheel 303 and the rotating column 302 to rotate. Through the self-locking characteristics of the worm wheel 303 and the worm gear 301, the cover 305 is deflected and then enters the water pipe. To fix the elastic bandage, pull the elastic bandage roll under the cutter 408 while pulling the fixing plate 409 by hand. This causes several fixing pins 413 to move out of the pin slots 414. Then, insert one end of the elastic bandage into the outside of the pin slots 414. During the pulling process, the fixing plate 409 drives the movable column 412 to move within the fixing column 410, thereby compressing the spring 411. When one end of the elastic bandage is inserted into the outside of the pin slots 414, the fixing plate 409 is released. The fixed plate 409 is reset by two springs 411, which causes several fixing nails 413 to press one end of the elastic bandage into the nail groove 414. The bandage is then screwed onto the padding roller frame 401 via the threaded cap 402, thus limiting and fixing the elastic bandage roll. This allows the burn patient's arm to be placed on the elastic bandage. The bandage is supported by a rubber support block 202 and a support platform 2 below, as the burn patient's arm is often irregularly bent due to swelling or scar contracture. The 202 soft silicone material can slightly deform to conform to the shape of the arm, filling the gap between the bandage and the skin. This avoids the problem of traditional rigid support tables causing the bandage to compress the wound edges, leading to blisters or abrasions, due to the "suspended" nature of the support table. Furthermore, when doctors change dressings, exudate, bloodstains, or sloughed necrotic tissue, as well as medications such as saline solution, iodine, povidone-iodine solution, hydrogen peroxide solution, potassium permanganate solution, benzalkonium bromide solution, and silver sulfadiazine cream, are intercepted by the support table, preventing them from flowing to the ground and reducing the risk of cross-infection.

[0047] After the burn patient's wound is treated, it is re-bandaged. The doctor presses the support rod 404 by hand. The support rod 404 drives the movable columns 407 at both ends to compress the spring 406 within the fixed column 405, thereby causing the cutter 408 to cut the elastic bandage. The removed gauze and the elastic bandage that was just placed underneath are taken out and placed in the medical waste bin. Water is supplied to the water pipe 206 to rinse the saline, iodine, povidone-iodine solution, hydrogen peroxide solution, potassium permanganate solution, benzalkonium bromide solution, silver sulfadiazine cream and other related medicines sprayed in the storage tank 207. The ultraviolet disinfection operation is repeated to facilitate dressing changes for the next burn patient.

[0048] By using rubber support blocks 202 and elastic bandages for soft, bacteria-resistant support, and facilitating quick and stable replacement of elastic bandage padding, as well as convenient and rapid cleaning and ultraviolet disinfection of liquid medications, cross-infection is prevented during dressing changes for each burn patient. During dressing changes, the elastic bandage padding can be easily replaced, ensuring the hygiene and fit of the bandages, while the interior of the support platform 2 can be thoroughly disinfected. This dual protection, encompassing both operational procedures and environmental cleanliness, effectively blocks cross-infection routes, providing a safe dressing change environment for patients and preventing cross-infection between different patients due to dressing change procedures and environmental factors. This ensures that each dressing change is performed in a sterile environment.
