Description

Technical Field

[0001] The present invention relates to the technical field of dressing change devices, and particularly to a rapid dressing change device for clinical use. Background Art

[0002] When performing daily care and recovery treatment on patients, it is necessary to perform nursing disinfection on the affected area of the patient to ensure the cleanliness of the affected area, prevent the spread and infection of germs, and reduce the treatment and recovery period of the patient; in hospitals, patients with poor tolerance are often encountered. When cleaning and changing dressings, medical staff usually directly clean the affected area of the patient with alcohol or cleaning solution. Generally, debridement techniques are used, and the affected area of the patient is disinfected by a circular technique from the inside to the outside. Since pain often accompanies the cleaning and disinfection, some are related to the operation techniques of doctors and are easy to touch the wound. In addition, due to pathogenic pain, some patients with poor tolerance will cause random movement. Therefore, secondary injuries are extremely likely to occur. Moreover, during disinfection, due to the random movement of the patient, the disinfection work is more troublesome, the dosage of medicine is likely to increase, resulting in waste, and the dressing change process is relatively cumbersome. Then, it is necessary for medical staff to run to the rinser to rinse the medical utensils manually, which is not time-saving and labor-saving. A rapid dressing change device for clinical use should be designed to solve the problem. Summary of the Invention

[0005] Preferably, a medicine administration component for changing the rotation angle of the rotating block on the support rod is installed between the two connecting rods. After the two sides of the medicine administration component contact the outer ring of the connecting rod, the first gear is attached to the support plate.

[0006] Preferably, the administration component includes a first cylinder suspended on one side of the top of the support plate. A movable block is fixedly installed at the bottom of the first cylinder. The movable block is slidably connected to the support plate. A first chuck is suspended at the bottom of the movable block.

[0007] Preferably, the bottom of the movable block has a rod-shaped structure. A fixed disk is fixedly connected to the outside of the rod-shaped structure. The bottom of the rod-shaped structure is fixed to the first chuck. A second spring is fixedly connected between the fixed disk and the second chuck.

[0008] Preferably, hinge rods are respectively hinged at both ends of one side of the bottom of the fitting plate. A second magnet is fixedly connected to the end of each hinge rod. First magnets are fixedly connected to both ends of the other side of the bottom of the fitting plate. The first magnets and the second magnets are attracted and fixed together with opposite magnetic poles.

[0009] Preferably, a second cylinder is suspended on the other side of the top of the support plate. A fixed block is fixedly connected to the bottom of the support plate.

[0013] Compared with the prior art, the present invention has the following beneficial effects: The elastic ring can be retained between the gauze and the skin. Since the elastic ring has a certain volume, it is convenient to have a gap between the gauze and the skin, facilitating skin respiration, reducing the generation of bacteria at the wound, and ensuring good recovery of the patient's injured area. Therefore, the elastic ring is a disposable object. When removing the gauze for dressing change at the bottom of the gauze, the elastic ring can be pulled out to separate the gauze from the body, improving the dressing change speed. In addition, after the two connecting rods are close to the patient's injured area, the connecting rods are made of rigid material, and when the patient's body shakes due to pain, it can also play a role in pressing the surrounding of the body, thereby preventing the disinfectant from generating a certain gap due to the body shaking and the elastic ring, and the disinfectant gap from entering the wound interior; When the fitting plate is close to the top of the connecting rod, the distance between the fitting plate and the rotating block is relatively short, so the angle between the two connecting rods is relatively large. And when the fitting plate is closer to the bottom of the connecting rod, the angle between the two connecting rods is relatively small. Therefore, the angle between the connecting rods can also be adjusted according to the position height of the fitting plate, facilitating a pair of connecting rods to accurately capture the surrounding of the wound and improving the coverage accuracy of the elastic ring for the wound.

[0016] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0017] Please refer to Figures 1-11, A rapid dressing change device for clinical use, including a push frame 1. A plurality of rollers 3 are installed at the bottom of the push frame 1. Both ends of the top of the push frame 1 are rotatably connected with first lead screws 4. An activity plate 2 is movably connected between a pair of the first lead screws 4. The middle part of one side of the activity plate 2 is rotatably connected with a second lead screw 5. A lifting plate 7 is movably connected to the second lead screw 5. A third lead screw 9 is rotatably connected to the lifting plate 7. A support plate 10 is threadedly connected to the third lead screw 9. A plurality of teeth are arranged on both sides of the support plate 10. The bottom of the lifting plate 7 is slidably connected with a fence 21. A pair of support rods 22 are fixedly connected inside the fence 21. A rotating block 23 is swingably connected to each support rod 22. A connecting rod 31 is fixedly connected to the bottom of the rotating block 23. The top of the connecting rod 31 is slidably connected with an activity disc 26. A third spring 25 is fixedly connected to the bottom of the activity disc 26. A first gear 24 is fixedly installed on the top of the activity disc 26. Each first gear 24 meshes and drives with the teeth on the side of the support plate 10. A snap ring 32 is detachably connected between the bottoms of the two connecting rods 31. First, the physician puts the spare objects used during dressing change on the lower partition of the push frame 1, and then the physician holds the push frame 1 and pushes it to the patient's side. Then, the physician rotates each first lead screw 4 with both hands at the same time. During the rotation of a pair of the first lead screws 4, the activity plate 2 moves towards the outside of the push frame 1 and closer to the patient. Finally, after the activity plate 2 approaches the patient, the rotation of the first lead screw 4 is stopped. Then, the disinfected snap ring 32 is sleeved between the bottoms of the two connecting rods 31. Then, the physician rotates the second lead screw 5 with one hand, so that the lifting plate 7 descends, driving the fence 21 to descend. The fence 21 further drives the two connecting rods 31 to descend, making the two connecting rods 31 close to the edges of the patient's wound. Then, the physician rotates the third lead screw 9, so that the whole support plate 10 descends, making the first gears 24 on both sides of the support plate 10 mesh and drive with the teeth of the support plate 10, compressing the third spring 25 driven by the activity disc 26. When the activity disc 26 gradually approaches the rotating block 23 and becomes shorter, the included angle between the activity disc 26 and the support plate 10 becomes smaller, making it easier for the connecting rod 31 to expand outwards, so that the snap ring 32 generates elastic force after being stressed and adheres around the wound, providing a blocking effect between the wound periphery and the outside. Thus, when the physician disinfects around the wound, the disinfection method still uses the existing debridement and disinfection techniques, disinfecting the skin cyclically in a counterclockwise direction from the inside to the outside around the snap ring 32. Since there is a snap ring 32 around the skin wound, it is difficult for the disinfectant to enter the wound, thereby improving the comfort of the patient during dressing change. Then, the dressing gauze is placed on the wound to end the dressing change work. Specifically as follows: It is worth mentioning that the elastic ring 32 can also be retained between the gauze and the skin. Since the elastic ring 32 has a certain volume, it is convenient for there to be a gap between the gauze and the skin, facilitating skin respiration, reducing the generation of bacteria at the wound, and ensuring good recovery of the patient's injured area. Therefore, the elastic ring 32 is a disposable object. When the gauze is disassembled for dressing change at the bottom of the gauze, the elastic ring 32 can be pulled out to separate the gauze from the body, improving the dressing change speed. In addition, after the two connecting rods 31 are close to the patient's injured area, since the connecting rods 31 are made of rigid material, when the patient's body shakes due to pain, it can also play a role in pressing the surrounding area of the body, thereby preventing the disinfectant from generating a certain gap with the elastic ring 32 due to body shaking, and the disinfectant gap from entering the wound.

[0018] Furthermore, a drug delivery component for changing the rotation angle of the rotating block 23 on the support rod 22 is installed between the two connecting rods 31. After the two sides of the drug delivery component contact the outer ring of the connecting rod 31, the first gear 24 is fitted on the support plate 10; the drug delivery component includes a first cylinder 11 suspended on one side of the top of the support plate 10. A movable block 13 is fixedly installed at the bottom of the first cylinder 11. The movable block 13 is slidably connected to the support plate 10. A first chuck 17 is suspended at the bottom of the movable block 13. A second chuck 18 is meshed and driven at the top of the first chuck 17. The edge of the second chuck 18 extends outwards, and a fitting plate 15 is fixedly installed at its bottom. Both ends of the fitting plate 15 have upwardly turned-up flanges. The flanges of the fitting plate 15 are in contact with the connecting rod 31. If the wound opening is relatively large and the expansion angle between the two connecting rods 31 is relatively large, the elastic ring 32 will generate a reverse elastic force on the connecting rod 31. Therefore, the drug delivery component can be used to prevent the two connecting rods 31 from rebounding. If the connecting rod 31 is to rebound, it is difficult for the connecting rod 31 to accurately fit the wound edge. Due to the flanges at both ends of the fitting plate 15, after the flanges contact the outside of the connecting rod 31, the fitting plate 15 can slide along the outer ring of the connecting rod 31. Therefore, only by controlling the lifting of the fitting plate 15 through the background, the two ends of the fitting plate 15 can be continuously in contact with the outer ring of the connecting rod 31. When the background controls the first cylinder 11 to rise or fall, the movable block 13 will drive the first chuck 17 to fall or rise. The two ends of the fitting plate 15 should not exceed the height of the rotating block 23 to prevent the negative effect of making it difficult for the first gear 24 to contact the side of the support plate 10. Combined with the attached Figure 5 and 6As shown, when the fitting plate 15 is close to the top of the connecting rod 31, the distance between the fitting plate 15 and the rotating block 23 is relatively short, so that the angle between the two connecting rods 31 is relatively large. When the fitting plate 15 is closer to the bottom of the connecting rod 31, the angle between the two connecting rods 31 is relatively small. Therefore, the angle between the connecting rods 31 can also be adjusted according to the position height of the fitting plate 15, which is convenient for a pair of connecting rods 31 to accurately capture the periphery of the wound and improve the coverage accuracy of the elastic ring 32 for the wound.

[0019] The bottom of the movable block 13 has a rod-shaped structure. A fixed disk 20 is fixedly connected to the outside of the rod-shaped structure. The bottom of the rod-shaped structure is fixed to the first chuck 17. A second spring 19 is fixedly connected between the fixed disk 20 and the second chuck 18.

[0020] Further, both ends of one side of the bottom of the fitting plate 15 are respectively hinged with hinge rods 1501. A second magnet 1503 is fixedly connected to the end of each hinge rod 1501. Both ends of the other side of the bottom of the fitting plate 15 are fixedly connected with first magnets 1502. The first magnets 1502 and the second magnets 1503 are attracted to each other with opposite polarities and fixed together. Among them, the doctor can separate the first magnet 1502 and the second magnet 1503, then fold the medical gauze several times after applying medicine and place it at the bottom of the fitting plate 15 (there should be operations before preparation). Then, use one hand to reset the hinge rod 1501, so that the first magnet 1502 and the second magnet 1503 are attracted to each other again, so that the gauze stays at the bottom of the fitting plate 15, simplifying the steps of clinical operation.

[0021] Further, on the other side of the top of the support plate 10, a second cylinder 12 is suspended. The bottom of the support plate 10 is fixedly connected with a fixed block 14. At the bottom of one side of the second chuck 18, a first spring 1801 is fixedly connected. The top of the first spring 1801 is fixedly connected with a fixed hanging ear 1802. The fixed hanging ear 1802 is slidably connected with the second chuck 18. One end of the fixed hanging ear 1802 is fixedly connected with a guide groove 16. The bottom of the second cylinder 12 is fixedly connected with a driving rod. The bottom of the driving rod is slidably connected with the guide groove 16. The bottom of the guide groove 16 is slidably connected with a through block 1601 at the bottom. If the wound is in an inclined state, the doctor can rotate the fitting plate 15 with one hand, so that the fitting plate 15 drives the second chuck 18 to rotate, the second chuck 18 drives the fixed hanging ear 1802 to rotate on one side, the fixed hanging ear 1802 drives the guide groove 16 to rotate synchronously, and the bottom of the guide groove 16 rotates on the through block 1601 (the connection structure diagram of the through block 1601 and the guide groove 16 is not shown in the figure and can be understood as a mortise and tenon connection structure), so that the gauze covers the periphery of the wound. Then, the second cylinder 12 can be driven to descend in the background, so that the second cylinder 12 drives the driving rod to descend, the driving rod drives the guide groove 16 to descend, the first spring 1801 is compressed, the guide groove 16 drives the through block 1601 to descend, and after the through block 1601 contacts the top of the gauze, the gauze is retained on the skin, so that the fitting plate 15 can cope with wounds at various angles and improve the adaptability of the device.

[0022] Further, a second gear 27 is rotatably connected to the bottom of each connecting rod 31. A lifting rack 28 is slidably connected to the bottom of each connecting rod 31 near the second gear 27. The lifting rack 28 and the second gear 27 are in meshing transmission. A through rod 30 is slidably connected between the opposite sides of the bottom of each connecting rod 31. One end of each lifting rack 28 is fixedly connected with a wedge block 29. The other end of the through rod 30 contacts the spring ring 32. The bottom of the lifting rack 28 and the top of the wedge block 29 are in alignment. After the device installs the gauze on the skin and needs to evacuate the scene, when the spring ring 32 is disinfected and placed between the two connecting rods 31, the spring ring 32 will inevitably be stretched. The spring ring 32 should be retained under the gauze. When the spring ring 32 is separated from the device, it has a certain elasticity. In order to avoid secondary infection caused by the spring ring 32 entering under the gauze due to contact with the human hand, the doctor needs to rotate the second gear 27 at the bottom of the connecting rod 31. When the second gear 27 rotates, the lifting rack 28 descends. The descent of the lifting rack 28 drives the wedge block 29 to move towards the inner side of the connecting rod 31, driving the through rod 30 to move between the two connecting rods 31 towards the separation point of the driving spring ring 32.

[0023] Further, both ends of one side of the bottom of the lifting plate 7 are fixedly connected with first placing rods 34, and both ends of the other side of the bottom of the lifting plate 7 are fixedly connected with second placing rods 36. Placing disks are fixedly connected to the bottoms of the first placing rods 34 and the second placing rods 36. A tape reel 33 is detachably connected to one side of the placing disk at the bottom of the first placing rod 34. A movable claw 35 is rotatably connected to the bottom of each first placing rod 34. A handle rod is fixed between the two movable claws 35. A stab cone 37 is arranged at one end of each movable claw 35. The initial position of the tape on the tape reel 33 is at the placing disk at the bottom of the second placing rod 36. After the gauze is installed at the bottom of the fitting plate 15 and the through block 1601 retains the gauze on the skin, the doctor rotates the movable claw 35 with one hand, so that the stab cone 37 contacts the tape reel 33, and cuts the tape between the placing disks fixedly connected to the bottoms of the first placing rod 34 and the second placing rod 36. The cut tape will immediately adhere above the gauze, and both ends of the tape extend beyond the gauze. Therefore, the doctor can quickly fix the gauze around the wound and improve the dressing change speed. As shown in the attachment Figure 10 As shown, there is a certain distance between the movable claw 35 and the tape reel 33 so that after the tape is cut, there is still a small section exposed outside for easy pulling and use next time, and then one end of the tape is adhered to the placing disk at the bottom of the second placing rod 36.

[0024] A control cabinet 8 is fixedly installed on the other side of the movable plate 2. Disinfection boxes 6 are fixedly installed at both ends of one side of the top of the lifting plate 7. The disinfection boxes 6 are connected to spray heads through pipelines (the spray heads are existing devices not shown). The disinfection boxes 6 can disinfect the used supplies in time through the spray heads, improving the portability of the overall device.

[0025] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirits of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
